ST 3000 Smart Transmitters

About the transmitter

The ST 3000 Smart Transmitter comes in a variety of models for measurement applications involving one of these basic types of pressure:

Differential Pressure

Gauge Pressure

Absolute Pressure

The transmitter measures the process pressure and transmits an output signal proportional to the measured variable over a 4 to 20 milliampere, two-wire loop. Its major components are an electronics housing and a meter body as shown in Figure 1 for a typical differential pressure model transmitter.

ElectronicsHousing

Meter Body

Series and model number data

Honeywell’s line of ST 3000 Smart Transmitters includes these two series designations:

Series 100 Series 900

Each series includes several models to meet various process pressure measurement and interface requirements. Each transmitter comes with a nameplate located on the top of the electronics housing that lists its given “model number”. The model number format consists of a Key Number with several Table selections as shown below.

Key Number M

,S T D 1 2 0 E 1 H 0 0 0 0 0 S 1 CB X X X X

You can quickly identify what series and basic type of transmitter you have from the third and fourth digits in the key number. The letter in the third digit represents one of these basic transmitter types:

A = Absolute Pressure

D = Differential Pressure

F = Flange Mounted

G = Gauge Pressure

R = Remote Seals

The number in the fourth digit matches the first digit in the transmitter Series. Thus, a “1” means the transmitter is a Series 100 and a “9” is a Series 900.

For a complete breakdown of the Table selections in your model number, please refer to the appropriate Specification and Model Selection Guide that is provided as a separate document.

ATTENTION

Be aware that previous vintages of the ST 3000 transmitter with designations of Series 100, Series 100e, Series 600, and Series 900 have been supplied at various times since the ST 3000 was introduced in 1983. While all these transmitters are functionally alike, there are differences in housing and electronics design.

This manual only applies for Series 100, Release 300 and Series 900, Release 300 transmitters furnished with the HART communications option (HART 5 ad HART 6). Release 300 transmitters can be identified by the “R300” designation on the nameplate.

HART Communicator

Transmitter adjustments

Except for optional local zero and span adjustments, the ST 3000 has no physical adjustments. You need a HART communicator to make any adjustments in a ST 3000 with the HART communications option.

Transmitter operator interface

The HART communicator (Model 275 or Model 375) is connected to the loop wiring of the ST 3000 transmitter for direct communication with the transmitter. The hand-held communicator “talks” with a transmitter through serial digital signals over the 4 to 20 milliampere line used to power the transmitter. A request/response format is the basis for the communication operation. The transmitter’s microprocessor receives a communication signal from the communicator, identifies the request, and sends a response message.

Figure 3 shows a simplified view of the communication interface provided by the communicator.

Figure 3 Typical Communication Interface

HART 5 or HART 6?

Model 275 is compatible with HART 5 only; Model 375 is compatible with HART 5 and HART 6.

The HART Communicator Purpose

The communicator allows you to adjust transmitter values, or diagnose potential problems from a remote location such as the control room. You use the communicator to:

Configure: Define and enter the transmitter’s operating parameters.

Monitor: Read the input pressure to the transmitter in engineering units and the transmitter’s output in milliamperes or percent.

Display: Retrieve and display data from the transmitter or the communicator’s memory.

Check current output: Use the transmitter to supply the output current desired for verifying analog loop operation, troubleshooting, or calibrating other components in the analog loop.

Troubleshoot: Check status of transmitter operation and display diagnostic messages to identify transmitter, communication, or operator error problems.

For more specific information, refer to the appropriate Specification and Model Selection Guide. In transmitters with Graphite Gaskets, rating of 50 psi remains unchanged while ratings of 4,500 psi are reduced to 3,625 psi (250 bar). Flange Adapters with Graphite Gaskets have a 3,000 psi rating.

Note 2: To convert bar values to kilopascals (kPa), multiply by 100. For example, 3.5 bar equals 350 kPa.

Considerations for HART communicator Guidelines

When using the communicator to communicate with the transmitter:

Be sure the power supply voltage does not exceed 42 Vdc (30 Vdc for intrinsically safe loops).

Be sure there is at least 250 ohms of resistance between the communicator and the power supply for proper communication.

Refer to communicator product manual for such information as operating limits.

Considerations for Local Smart Meter Option If your transmitter is to be installed and operated with one of the integral smart meter options, please note the Smart meter specifications and operating conditions for the meter located in Appendix A of this manual.

Overview

About this section

This section provides information about installing the ST 3000 transmitter. The topics in this section include:

Mounting the ST 3000 transmitter - various mounting methods are described and can be used depending upon the transmitter type.

Piping the transmitter to the process – connecting the transmitter meter body to the process piping or tank connection.

Wiring the transmitter – connecting the loop wiring and ground conductors to the transmitter, and information is given on connecting local and remote indicating meters to the transmitter.

Mounting ST 3000 Transmitter

Summary

You can mount all transmitter models (except flush mount models and those with integral flanges) to a 2-inch (50 millimeter) vertical or horizontal pipe using our optional angle or flat mounting bracket, or a bracket of your own. Flush mount models are mounted directly to the process pipe or tank by a 1” weld nipple. Those models with integral flanges are supported by the flange connection.

Figure 7 shows typical bracket mounted and flange mounted transmitter installations for comparison.

Dimensions

Detailed dimension drawings for given transmitter series and types are listed in Section 13 in this manual for reference. Note that abbreviated overall dimensions are also shown in the specification sheets for the given transmitter models.

The procedures following assume that the mounting dimensions have already been taken into account and the mounting area can accommodate the transmitter.

Mounting Transmitters with Small Absolute or Differential Pressure Spans

To minimize positional effects on pressure measurement and calibration (zero shift), take the appropriate mounting precautions that follow for transmitters with small pressure spans.

Absolute Pressure and In-line Transmitters

For absolute pressure and inline transmitters you must ensure that the transmitter is vertical when mounting it. You do this by leveling the transmitter side-to-side and front-to-back. See Figure 8 for suggestions on how to level the transmitter using a spirit balance.

Absolute pressure models

CenterSection

ProcessHead

Position spirit balance oncenter section of meterbody only.


In-line models

Mount transmitter vertically to assure best accuracy. Position spirit balance on pressure connection surface of AP body.

Figure 8 Leveling Transmitters

CAUTION

The mounting position of a model STA122 or STA922 Absolute Pressure Transmitter or a model STD110 Draft Range Differential Pressure Transmitter is critical as the transmitter spans become smaller. A maximum zero shift of 2.5 mm Hg for an absolute transmitter or 1.5 in H2O for a draft range transmitter can result from a mounting position which is rotated 90 degrees from vertical. A typical zero shift of 0.12 mm Hg or 0.20 in H2O can occur for a 5 degree rotation from vertical.

Differential Pressure Transmitters

For a transmitter with a small differential pressure span (Model STD110, for example), you must ensure that the transmitter is vertical when mounting it. You do this by leveling the transmitter side-to-side and front-to-back. See Figure 8 for suggestions on how to level the transmitter using a spirit balance. You must also zero the transmitter by following the steps in Table 7 below.

Table 7 Zero Corrects Procedure for Transmitters with a Small Differential Pressure Span

Step Action

1 Attach the transmitter to the mounting bracket but do not completely tighten the mounting bolts.

2 Connect a tube between the input connections in the high pressure (HP) and low pressure (LP) heads to eliminate the affects of any surrounding air currents.




Step Action

3 Connect 24 Vdc power to the transmitter and connect a milliammeter in series in the loop circuit to read the transmitter’s output current. See figure for typical connections.

Flange mounting

Transmitters that are furnished with integral flange connections (models STFxxx), are bolted directly to the process flange connection. Figure 9 shows a typical installation for a transmitter with the flange on the high pressure (HP) side so the HP diaphragm is in direct contact with the process fluid. The low pressure (LP) side of the transmitter is vented to atmosphere (no connection).

To mount a flange mounted transmitter model, bolt the transmitter’s flange to the flange pipe on the wall of the tank.

ATTENTION

On insulated tanks, remove enough insulation to accommodate the flange extension.

Once the transmitter is mounted, the electronics housing can be rotated to the desired position. See Table 6, Step 4 for details.

It is the End User’s responsibility to provide a flange gasket and mounting hardware that are suitable for the transmitter’s service condition.

To prevent degradation of performance in Flush-Mounted Flanged Transmitters, exercise care to ensure that the internal diameter of the flange gasket does not obstruct the sensing diaphragm.

To prevent degradation of performance in Extended Mount Flanged Transmitters, ensure that there is sufficient clearance in front of the sensing diaphragm body.

Piping ST 3000 Transmitter

Piping Arrangements

The actual piping arrangement will vary depending upon the process measurement requirements and the transmitter model. Except for flush, flanged and remote diaphragm seal connections, process connections are made to ¼ or ½ NPT female connections in the process head of the transmitter’s meter body. For example, a differential pressure transmitter comes with double-ended process heads with ¼ NPT connections but they can be modified to accept ½ inch NPT through optional flange adapters. Some gauge pressure transmitters may have a ½ NPT connection that mounts directly to a process pipe.

The most common type of pipe used is ½ schedule 80 steel pipe. Many piping arrangements use a three-valve manifold to connect the process piping to the transmitter. A manifold makes it easy to install and remove or rezero a transmitter without interrupting the process. It also accommodates the installation of blow-down valves to clear debris from pressure lines to the transmitter.

Figure 13 shows a diagram of a typical piping arrangement using a three-valve manifold and blow-down lines for a differential pressure transmitter being used to measure flow.

Transmitter location

Table 10 lists the mounting location for the transmitter depending on the process.

Table 10 Suggested Transmitter Location for Given Processes

Process Suggested Location Explanation

Liquids 1. Below but close to the elevation of the process connection.

2. Level with or above the process connection.

1. This minimizes the static head effect of the condensate.

2. This requires a siphon to protect the transmitter from process steam. The siphon retains water as a “fill fluid.”

Gases Above the gas line The condensate drains away from the transmitter

ATTENTION

For liquid or steam, the piping should slope a minimum of 25.4 mm (1 inch) per 305 mm (1 foot). Slope the piping down towards the transmitter if the transmitter is below the process connection so the bubbles may rise back into the piping through the liquid. If the transmitter is located above the process connection, the piping should rise vertically above the transmitter; then slope down towards the flowline with a vent valve at the high point.

For gas measurement, use a condensate leg and drain at the low point (freeze protection may be required here). See Appendix C for some suggested freeze protection solutions.

ATTENTION

Care must be taken when installing transmitters on hot processes. The operating temperature limits for the device (as outlined in Table 3) must not be exceeded. Impulse piping may be used to reduce the temperature of the process that comes into contact with the transmitter meter body. As a general rule there is a 56C drop (100F) in the temperature of the process for every foot of 1/2" uninsulated piping.

General piping guidelines

When measuring fluids containing suspended solids, install permanent valves at regular intervals to blow-down piping.

Blow-down all lines on new installations with compressed air or steam and flush them with process fluids (where possible) before connecting these lines to the transmitter’s meter body.

Be sure all the valves in the blow-down lines are closed tight after the initial blow-down procedure and each maintenance procedure after that.



Installing flange adapter

Table 13 gives the steps for an optional flange adapter on the process head.

ATTENTION

Slightly deforming the gasket supplied with the adapter before you insert it into the adapter may aid in retaining the gasket in the groove while you align the adapter to the process head. To deform the gasket, submerse it in hot water for a few minutes then firmly press it into its recessed mounting groove in the adapter.

Table 13 Installing Flange Adapter

Step Action

1 Insert filter screen (if supplied) into inlet cavity of process head.

2 Carefully seat Teflon (white) gasket into adapter groove.

3 Thread adapter onto 1/2-inch process pipe and align mounting holes in adapter with holes in end of process head as required.

4 Secure adapter to process head by hand tightening 7/16-20 hex-head bolts.

4— Installation - Wiring ST 3000 Transmitter

Wiring ST 3000 Transmitter

Summary

The transmitter is designed to operate in a two-wire power/current loop with loop resistance and power supply voltage within the operating range shown in Figure 15. When option LP (lightning protection) and/or remote smart meter are selected, the voltage drop for these options must be added to the basic transmitter voltage of 10.8 V to determine VXMTR and RLOOP MAX. Additional consideration is required when selecting intrinsic safety barriers to insure that the barriers will supply VXMTR MIN including the required 250 ohms (typically within the barriers) for digital communications.

Transmitter Parameters:

RLOOP MAX = The maximum loop resistance (barriers plus wiring) that will allow proper transmitter operation.

Therefore, RLOOP MAX = (VSUPPLY MIN – VXMTR MIN) 21.8 mA

Where, VXMTR MIN = 10.8 V + VLP + VSM

VLP = 1.1 V, lightning protection option, LP

VSM = 2.3 V, remote smart meter (Please note that VSM should only be considered if a remote smart meter will be connected to the transmitter.)

Each transmitter includes an internal ground terminal to connect the transmitter to earth ground. A ground terminal can be optionally added to the outside of the electronics housing. While it is not necessary to ground the transmitter for proper operation, we suggest that you do so to minimize the possible effects of “noise” on the output signal and provide additional protection against lightning and static discharge damage. Note that grounding may be required to meet optional approval body certification. Refer to Section 3, CE Conformity (Europe) Notice for special conditions.

Optional lightning protection (option LP) can be ordered for transmitters that will be installed in areas highly susceptible to lightning strikes. Figure 17 shows the 5-screw terminal block used when the lightning protection option is ordered.

Barriers can be installed per manufacturer’s instructions for transmitters to be used in intrinsically safe applications.

Wiring connections

The procedure in Table 14 shows the steps for connecting loop power to the transmitter. For loop wiring and external wiring diagrams, refer to the installation drawings presented in Section 13. Detailed drawings are provided for transmitter installation in non-intrinsically safe areas and for intrinsically safe loops in hazardous area locations.

ATTENTION

All wiring must comply with local codes, regulations, and ordinances.

If you will be using the transmitter in a hazardous area, be sure to review the hazardous location reference data included in Appendix D of this manual before wiring and operating the transmitter.

Approval body requirements

If your transmitter was ordered with Table III option 3N for self-declared approval per 94/9/EC (ATEX4), you must use a power supply that includes a voltage limiting device that will keep the voltage to the transmitter from exceeding 42 Vdc. You can achieve this by using a battery as the supply or one of these voltage limiting means.

Double wound mains transformer per BS 3535 or equivalent.

An adequately rated zener diode whose voltage is not significantly higher than the rated voltage.

An adequately rated semiconductor voltage regulator.



Lightning protection

When your transmitter is equipped with optional lightning protection (option LP), you must connect a wire from the transmitter to ground as shown in Figure 17 to make the protection effective. We recommend that you use a size 8 AWG (American Wire Gage) or (8.37mm2) bare or green covered wire.

ElectronicsHousing

Figure 17 Ground Connection for Lightning Protection.

Process Sealing

The ST 3000, Series 100, 100e, 600, and 900, Smart Pressure Transmitters are CSA certified as “Dual Seal” devices in accordance with ANSI/ISA–12.27.01–2003, Requirements for Process Sealing between Electrical Systems and Flammable or Combustible Process Fluids.

Explosionproof Conduit seal

Transmitters installed as explosionproof in a Class I, Division 1, Group A Hazardous (Classified) Location in accordance with ANSI/NFPA 70, the US National Electrical Code (NEC), require a “LISTED” explosionproof seal to be installed in the conduit, within 18 inches of the transmitter. Crouse-Hinds® type EYS/EYD or EYSX/EYDX are examples of “LISTED” explosionproof seals that meets this requirement.

Transmitters installed as explosionproof in a Class I, Division 1, Group B, C or D Hazardous (Classified) Locations do not require an explosionproof seal to be installed in the conduit.

ATTENTION

Installation should conform to all national and local electrical code requirements.

WARNING

When installed as explosionproof in a Division 1 Hazardous Location, keep covers tight while the transmitter is energized. Disconnect power to the transmitter in the non-hazardous area prior to removing end caps for service.

When installed as nonincendive equipment in a Division 2 Hazardous Location, disconnect power to the transmitter in the non-hazardous area, or determine that the location is non-hazardous prior to disconnecting or connecting the transmitter wires.

Overview

About this section

This section tells you how to establish communications with the ST 3000 and make initial checks of the transmitter’s settings and configuration using a HART hand-held communicator. This section includes these topics:

Verifying that the HART communicator contains the proper software version for communicating the ST 3000 transmitter.

Making proper connections of the HART communicator to the ST 3000 transmitter.

Begin communications between the transmitter and the communicator.

Make initial checks to the transmitter, such as checking factory set configuration, verify write protect option and failsafe direction, and change if necessary.

Establishing Communications

Software compatibility

You need to make sure your HART communicator contains software that is compatible with the ST 3000 HART transmitter.

To check software revision contained in the communicator:

1. Turn on the communicator and access the “Offline” menu.

2. Press “4” to select the Utility menu.

3. Press “5” to select Simulation mode.

4. The Manufacturer menu appears. Select “Honeywell”.

5. Select Model “ST3000”.

6. View the software revisions available for the selected model.

The software versions that are compatible with the ST 3000 HART Release 300 Smart Transmitter are:

ST 3000 HART 5 Version: Dev v2 (Device version 2) DD v1 (Device Description version 1)

ST 3000 HART 6 Version: Dev v4 (Device version 4) DD 2 (Device Description version 2)

ST3000 HART 6 Advanced Diagnostics Version: Dev v5 (Device version 5) DD v1 (Device Description version 1)


5— Getting Started - Establishing Communications

Upgrading HART communicator software

The memory module in the HART communicator is programmed with device descriptions for specific HART-compatible devices. These device descriptions allow the communicator to recognize and “talk to” the compatible devices. If you find that your communicator does not contain the necessary application software and device descriptions, contact your Honeywell sales representative about upgrading your communicator. See also the product manual that was supplied with your communicator for further information.



Connecting the communicator

You connect the hand-held communicator directly to signal terminals on the transmitter’s terminal block or at any convenient location in the 4 to 20 milliampere loop wiring. (Polarity of the communicator connection does not matter.)

WARNING

When the transmitter’s end-cap is removed, the housing is not explosionproof.

Figure 18 shows typical communicator connections across loop wiring to a ST 3000 transmitter.

Starting communications

Once you connect the communicator to the transmitter, you are ready to start communicating with the transmitter. The procedure in Table 15 outlines the steps for starting communications with an ST 3000 transmitter without an assigned tag number.

Table 15 Starting Communications with Transmitter

Step Action

1 Turn on communicator. The communicator runs a self-test check then determines if it is connected to a transmitter.

2 If you receive a communication error message (No Device Found), check the following:

Loop resistance: Is there a minimum of 250 ohms resistance between the communicator and the power supply?

Power supply: Is power applied? Is there greater than 11 volts at the transmitter? Are you within the operating area shown in Figure 15?

Correct any problems, then try communicating again.

If the message, or any other error message, appears again, refer to Section 11 – Troubleshooting for probable cause.

3 If the transmitter is reporting any status messages, which will be displayed at this time, refer to Section 11 – Troubleshooting for more information.

When the “Online” display—similar to the one below—appears, you have established communications with the transmitter.

4 After reviewing the transmitter data, press EXIT which takes you back to the “Device setup” display.

Transmitter write protection option

The ST 3000 transmitters have a transmitter security option, also known as a “write protect option,” which is jumper-selectable. When the write protect option is ordered, transmitters are shipped with a default jumper position for read-only. This means that the transmitter’s configuration database can not be overwritten. To allow read/write access, the jumper can be moved to the read/write position. When the write protect option is not ordered access is read/write. If you do want to change the jumper position, refer to the procedure in Section 8. Figure 19 below shows the location of the write protect jumper on the PWA. Note that if the SL (SIL option) has been specified in the model number and the user intends to operate the device in the safety mode, then the write protect jumper must be in the write protect position.

Figure 19 Write Protection and Failsafe Direction Jumper Location

Failure mode (Failsafe) alarm jumper

ST 3000 transmitters are shipped with a default failsafe direction of upscale. This means that the transmitter’s output will be driven upscale (maximum output) when the transmitter detects a critical status.

You can change the direction from upscale to downscale (minimum output) by cutting jumper W1 on the transmitter’s PWA. If you do want to change the jumper position, refer to the procedure in Section 8. Figure 19 shows the location of failure mode alarm jumper on the PWA.



Local smart meter display indications

If your ST 3000 transmitter is equipped with the smart meter option, you can check the status of all the indicators on the local smart meter LCD display by cycling power to the transmitter. The meter runs a brief self-test whenever power is applied to the transmitter. All the display indicators are lit during the self-test as shown in Figure 20. (Note that the display may revert to dashes (– – –) after the self-test until the transmitter initializes all its functions.)

About this section

This section introduces you to ST 3000 transmitter configuration. It identifies the parameters that make up the transmitter’s configuration database and provides procedures for entering values/selections for the given configuration parameters.

This section also provides an overview of the HART communicator, including data on menus and keyboard, descriptions of display selections and symbols, and information on making changes using the communicator.

6— Configuration - Configuration Overview

Configuration Overview

About configuration

Each ST 3000 transmitter includes a configuration database that defines its particular operating characteristics. You can use a communicator to change selected parameters within a given transmitter’s database to alter its operating characteristics. This process of viewing and/or changing database parameters is called “configuration.”

Figure 21 shows a graphic summary of the configuration process.

HARTCommunicator

Figure 21 Summary of Configuration Process

Transmitter configuration can be accomplished both on-line— with the transmitter powered up and connected to the communicator, or off-line— where you enter the configuration in the communicator and then store it in memory for later downloading to the transmitter

Communicator and ST 3000 transmitter memories

As shown in Figure 22, both the communicator and the ST 3000 transmitter have working memories. They serve as temporary storage areas for data exchanged between them during communications.

The transmitter also has a nonvolatile memory that is the permanent storage area for a backup copy of all the data held in the working memory. Nonvolatile memory retains its data even if the transmitter loses power.

The communicator has a second temporary storage area called the off-line memory (memory module or data pack). It serves as a permanent storage area for a saved configuration database. The memory module or data pack supports the communicator’s SEND function to restore a saved configuration database to a transmitter. Figure 22 shows the working relationship between communicator and transmitter memories during communications.

Figure 22 Communicator and ST 3000 Transmitter Memories

Copying transmitter configuration into nonvolatile memory

When setting up or configuring a ST 3000, whether you are changing one value or a configuration database, all configuration data must be copied into the transmitter’s non-volatile memory to ensure the security of the data.

Normally, thirty seconds after a value is changed, the transmitter automatically copies it from the transmitter’s working memory into nonvolatile memory. But, if you change a value and power is interrupted to the transmitter before the change is copied to nonvolatile memory, you will lose the data in the working memory and it will not be saved in nonvolatile memory.

Therefore, when data is sent (downloaded) to the transmitter, be sure power to the transmitter is not interrupted before it can be copied to nonvolatile memory.

ATTENTION

Since the engineering units affect the value of LRV and URV, it is recommended that you send the changed PV unit to the transmitter and then verify and change as required the values of LRV and URV.

6— Configuration - Range Values— Setting PV URV and PV LRV


Range Values— Setting PV URV and PV LRV You can set the LRV and URV by either keying in the desired values through the communicator keypad or applying the corresponding LRV and URV pressures directly to the transmitter.

Procedure for keying in LRV and URV

Table 20 gives the procedure for keying in the range values for a sample 5 to 45 inH2O range. (If inH2O is not the unit being used, follow the procedure in Table 19 to change it.)

ATTENTION

ST 3000 Smart Transmitters are factory calibrated with inches of water ranges using inches of water pressure referenced to a temperature of 39.2˚F (4˚C).

For a reverse range, enter the upper range value as the LRV and the lower range value as the URV. For example, to make a 0 to 50 psi range a reverse range, enter 50 as the LRV and 0 as the URV.

When setting the range using applied pressures (procedure in Table 21), the URV changes automatically to compensate for any changes in the LRV and to maintain the present span (URV – LRV). When entering the LRV with the keypad (in Table 20), the URV does not change automatically.

If you are using the applied pressure method and must change both the LRV and URV, always change the LRV first.

Pressure transfer function— Selecting Output Conformity

Output form options

You can select the transmitter’s output to represent either a straight linear calculation, or a square root calculation for flow measurement applications using a differential pressure type transmitter. Thus, we refer to the linear or the square root selection as the output conformity or the output form.

The procedure in Table 23 shows how to select the desired Output conformity.

Table 23 Selecting Output Conformity

Step Action



3 Select “PV xfer fnctn.”

4 Select either Linear or Square root, then press ENTER.

5 Either:



About square root output

For differential pressure transmitters measuring the pressure drop across a primary element, the flow rate is directly proportional to the square root of the differential or pressure drop. The ST 3000 transmitter’s output is automatically converted to equal percent of flow when its output conformity is configured as square root.

You can use these formulas to manually calculate the percent of flow for comparison purposes. (Note: This formula assumes that LRV = 0.)

∆P

Span • 100 = %P

Where, ∆P = Differential pressure input in engineering units

Span = Transmitter’s measurement span (URV – LRV)

%P = Pressure input in percent of span

Therefore, %P100 • 100 = % Flow

And, you can use this formula to determine the corresponding current output in milliamperes direct current.

(% Flow • 16 mA) + 4 mA = mA dc Output


EXAMPLE: If you have a differential pressure transmitter with a range of 0 to 100 inches of water with an input of 49 inches of water, substituting into the previous formulas yields:

49100 • 100 = 49%

49%100 • 100 = 70% Flow, and

70% • 16 + 4 = 15.2 mA dc Output

Square root dropout

To avoid unstable output at readings near zero, the ST 3000 transmitter automatically drops square root conformity and changes to linear conformity for low differential pressure readings. As shown in Figure 29, the point is near 0.5% of input for ST 3000 transmitters.

6— Configuration - PV damping— Adjusting Damping Time


PV damping— Adjusting Damping Time You can adjust the damping time to reduce the output noise. We suggest that you set the damping to the smallest value that the system can accept.

ATTENTION

The electrical noise effect on the output signal is partially related to the turndown ratio of the transmitter. As the turndown ratio increases, the peak-to-peak noise on the output signal increases. You can use this formula to find the turndown ratio using the range information for your transmitter.

Turndown Ratio = Upper Range Limit

(Upper Range Value – Lower Range Value)

EXAMPLE: The turndown ratio for a 400 inH2O transmitter with a range of 0 to 50 inH2O would be:

Turndown Ratio = 400

(50 – 0) = 81 or 8:1

The procedure in Table 24 outlines how to adjust the damping time.

5 When the desired selection is highlighted, press ENTER.


6 Either:



6— Configuration - Poll addr— Selecting Poll Address


Poll addr— Selecting Poll Address You can select the poll address for the transmitter that determines certain communications characteristics.

HART communications protocol provides for communications to multiple HART devices connected on the same loop (multidrop mode). In a multidrop mode, each device in the loop must be given a unique address.

For HART 5, a device with a poll address of 1 through 15 is identified as being in multidrop mode. Communication between the communicator and the devices takes place digitally, with the analog output remaining constant (fixed at 4 mA average).

A device with a poll address of 0 (zero) will provide a 4 to 20 mA analog output as well as receive requests and respond to commands from the HART communicator.

For HART 6, analog output mode is a separate menu item (Loop Current Mode). Poll Addresses may be set from 0 to 63.

The steps in Table 26 show how set the poll address of the transmitter. ST 3000 transmitters are shipped from the factory with poll address 0.

Overview

About this section

This section identifies typical start-up tasks associated with several generic pressure measurement applications. It also includes the procedure for running an optional analog output check.


Performing an analog output check

Start up procedures for the different types of pressure transmitters in various applications, such as

DP transmitter in a flow measurement

DP transmitter in a pressure measurement

DP transmitter in a liquid level measurement applications

GP transmitter in pressure or liquid level measurement applications

AP transmitter in a pressure measurement

DP transmitter with remote diaphragm seals in a liquid level measurement application

ATTENTION

All procedures in this manual assume a transmitter poll address of 0 (zero). See Section 6, for information about poll address.


7— Start-up - Start-up Tasks

Start-up Tasks

About start-up

Once you have installed and configured a transmitter, you are ready to start up the process loop. Start-up usually includes

Applying process pressure to the transmitter,

Checking zero input, and

Reading input and output.

You can also run an optional output check to “wring out” an analog loop prior to start-up.

Procedure reference

The actual steps in a start-up procedure will vary based on the type of transmitter and the measurement application. In general, you use the communicator to check the transmitter’s input and output under static process conditions, and make adjustments as required, before putting the transmitter into full operation with the running process.

Choose the applicable procedure to reference in this section from Table 28 based on your type of transmitter and the measurement application. The reference procedure will give you some idea of the typical tasks associated with starting up a transmitter in a given application.

** These applications also apply for GP and AP type transmitters equipped with remote seals. However, you can only confirm that input pressure correlates with transmitter output in processes using remote seal connections.


7— Start-up - Running Analog Output


Running Analog Output

Background

You can put the transmitter into a constant-current source mode to check out other instruments in the loop such as recorders, controllers, and positioners. Using the communicator, you can tell the transmitter to change its output to any value between 4 mA (1V or 0%) and 20 mA (5V or 100%) and maintain that output. This makes it easy to verify loop operation through the accurate simulation of transmitter output signals before bringing the loop on line. Note that the constant-current source mode is also referred to as the output mode.

ATTENTION

The transmitter does not measure the input or update the output while it is in the constant-current source mode.

Procedure

The procedure in Table 29 outlines the steps for using a transmitter in the constant current source mode.

Table 29 Using Transmitter in Constant-Current Source (Output) Mode

Step Action

1 Connect communicator across loop wiring and turn it on. If possible, locate communicator where you can also view receiver instrument in control loop. If you want to verify loop calibration, connect a precision milliammeter or voltmeter in loop to compare readings.

If you cannot empty tank, then go to Step 3.

If you can empty tank, then go Step 4.

3 Key in LRV that is equal to empty tank pressure. See Section 6.7 in this manual for details on keying in a range value.

Go to Step 7.

You can use this formula to calculate LRV in inH2O.

LRV = (H2 x Sf) x –1

H2 = Height of fixed reference leg in inches.

Sf = Specific gravity of remote seal fill fluid.

The LRV calculation must be multiplied by –1 since pressure in on the low side of the meter body.

EXAMPLE: If H2 equaled 12 feet and the fill fluid was silicone oil, substituting into the formula yields: LRV = (12 ft x 12 in x 0.94) x –1 LRV = –135.36 inH2O

ATTENTION

The specific gravity of silicone oil fill fluid (DC200) is 0.94 and fluorolube fill fluid (CTFE) is 1.84.

At “Process variables” display, read 0% output for corresponding empty tank pressure plus reference pressure H2. Check that milliammeter reading is 4 mA (0%) output.

7 If you cannot fill tank, then go to Step 8.

If you can fill tank, then go Step 9.

8 Key in URV that is equal to full tank pressure. See Range Values in Section 6 for details on keying in a range value.

Go to Step 12.

You can use these formulas to calculate URV in inH2O.

Span = H1 x SL

H1 = Height of variable head in inches.

SL = Specific gravity of measured liquid.

URV = Span + LRV

EXAMPLE: If H1 equaled 10 feet, the measured liquid was water, and the LRV equaled –135.36 inH2O; substituting into the formulas yields:

Span = 10 ft x 12 in x 1.00 Span = 120 inH2O

URV = 120 inH2O + –135.36 inH2O URV = –15.36 inH2O

8— Operation - Changing Default Failsafe Direction and Write Protect Jumpers

Changing Default Failsafe Direction and Write Protect Jumpers

Default failsafe direction

Transmitters are shipped with a default failsafe direction of upscale. This means that the transmitter’s output will be driven upscale (maximum output) when the transmitter detects a critical status.

The upscale failsafe action will drive an analog transmitter’s output to 20.8 mA or a downscale action will drive its output to 3.8 mA.

The HART communicator parameter PV AO Alrm Typ identifies the failsafe direction of the transmitter. The parameter indicates failsafe action as either Hi (upscale) or Lo (downscale).

Write protect option

Transmitters are shipped with a default jumper position for read and write access. This means that the transmitter’s configuration database can be overwritten.

Procedure

The procedure in outlines the steps for cutting the failsafe jumper and/or repositioning the write protect jumper on the transmitter’s Printed Wiring Assembly (PWA). Figure 39 shows the location of the jumpers on the PWA of ST 3000 Release 300 transmitters.

ESD HAZARD

The nature of the integrated circuitry used in the transmitter’s PWA makes it susceptible to damage by stray static discharges when it is removed from the transmitter. Follow these tips to minimize chances of static electricity damage when handling the PWA.

Never touch terminals, connectors, component leads, or circuits when handling the PWA.

When removing or installing the PWA, hold it by its edges or mounting bracket only. If you must touch the PWA circuits, be sure you are grounded by staying in contact with a grounded surface or wearing a grounded wrist strap.

As soon as the PWA is removed from the transmitter, put it in an electrically conductive bag or wrap it in aluminum foil to protect it.



Figure 39 Location of Failsafe and Write Protect Jumpers on PWA

Table 38 Changing Default Failsafe Direction

Step Action

1 Turn OFF transmitter power. Loosen end-cap lock and unscrew end cap from electronics side of transmitter housing.

2 If equipped with a local smart meter, carefully turn smart meter counterclockwise to remove it from PWA mounting bracket and unplug cable from connector on back of meter assembly.

3 Loosen two retaining screws and carefully pull mounting bracket and PWA from housing.

Using the retaining clip, unplug flex tape connector and 2-wire power connector from PWA, and remove PWA. See figure.

Connectors

Retaining Clip

PWAElectronicsHousing




ATTENTION

The PWA board has components on both sides. The failsafe jumper is located on the side with the most components, which is also the same side as the flex tape and power connector pins.

4 With the PWA component side (from which you unplugged the flex tape and power

connectors) facing you and referring to Figure 39, locate

Failsafe jumper (W1). If you want to change the failsafe action from upscale to downscale, cut jumper in half with a small wire cutter.

5 Reverse steps 2 and 3 to reassemble mounting bracket and PWA in transmitter housing.

ATTENTION

Be sure to orient local smart meter for proper viewing through end-cap window. You can rotate the meter mounting orientation in 90 degree increments.

6 We recommend that you lubricate end-cap O-ring with silicon grease such as Dow Corning

#33 or equivalent before you replace end cap.

7 Turn ON transmitter power.

Table 39 Changing Write Protect Jumper

Step Action

1 Turn OFF transmitter power. Loosen end-cap lock and unscrew end cap from electronics side of transmitter housing.

2 If equipped with a smart meter, carefully turn smart meter counterclockwise to remove it from PWA mounting bracket. Move the smart meter to one side in order to gain access to the write protect jumper. Refer to Figure 39.

3 Reposition the write protect jumper as required. See Figure 36 for jumper positions.

4 Reverse step 2 to reassemble smart meter if applicable.

ATTENTION

Be sure to locate smart meter for proper viewing through end-cap window. You can rotate the meter mounting in 90 degree increments.

5 We recommend that you lubricate end cap O-ring with silicone grease such as Dow Corning #33 or equivalent before you replace end cap.

6 Replace end cap.

10— Maintenance - Introduction

10— Maintenance

Introduction

About this section

This section provides information about preventive maintenance routines and replacing damaged parts. The topics covered in this section are:

Preventive maintenance of the meter body barrier diaphragms and process piping to the transmitter.

Replacement of damaged parts such as the transmitter PWA and meter body.

Preventive Maintenance

Maintenance routines and schedules

The ST 3000 transmitter itself does not require any specific maintenance routine at regularly scheduled intervals. However, you should consider carrying out these typical inspection and maintenance routines on a schedule that is dictated by the characteristics of the process medium being measured and whether blow-down facilities or purge systems are being used.

Check piping for leaks.

Clear the piping of sediment or other foreign matter.

Clean the transmitter’s pressure chambers including the barrier diaphragms.

Inspecting and Cleaning Barrier Diaphragms Depending on the characteristics of the process medium being measured, sediment or other foreign particles may collect in the process head cavity/chamber and cause faulty measurement. In addition, the barrier diaphragm or diaphragms in the transmitter’s meter body may become coated with a residue from the process medium. The latter is also true for external diaphragms on flange mount and remote seal type transmitters.

In most cases, you can readily remove the process head or heads from the transmitter’s meter body to clean the process head cavity and inspect the barrier diaphragm or diaphragms. For flange mount and remote seal diaphragms, you may only need to run a purge line in the tank to rinse off the face of the diaphragm.

Procedure

The procedure in Table 43 outlines the general steps for inspecting and cleaning barrier diaphragms. You may have to modify the steps to meet your particular process or transmitter model requirements. Figure 42 shows an exploded view of a DP transmitter’s meter body for reference.


10— Maintenance - Inspecting and Cleaning Barrier Diaphragms

Table 43 Inspecting and Cleaning Barrier Diaphragms

Step Action

1 Close all valves and isolate transmitter from process. Open vent in process head to drain fluid from transmitter’s meter body, if required.

ATTENTION

We recommend that you remove the transmitter from service and move it to a clean area before taking it apart.

2 Remove nuts from bolts that hold process head or heads to meter body. Remove process heads and bolts. See Figure 41.

3 Remove O-ring and clean interior of process head using soft bristle brush and suitable solvent.

4 Inspect barrier diaphragm for any signs of deterioration or corrosion. Look for possible residue and clean if necessary.

If diaphragm is dented, has distorted convolutions or radial wrinkles, performance may be affected. Contact TAC for assistance.

5 Replace O-ring.

ATTENTION

We recommend that you install a new O-ring whenever a process head is removed for cleaning.

The process head for a GP or an AP transmitter with single-head design has two O-ring grooves. A large one which is 2 inches (50.8 mm) in diameter and a small one which is 1.3 inches (33 mm) in diameter as shown in the following illustration. On high pressure model STG180, GP transmitters, use the small O-ring in the smaller/inner groove. On other models of GP and AP transmitters, use a large O-ring in the larger/outer groove. Never use both O-rings together.

Larger O-ring groove for lower pressure applications

11— Calibration - Introduction

11— Calibration

Introduction

About this section

This section provides information about calibrating the transmitter’s analog output and measurement range. It also covers the procedure for resetting calibration to default values as a quick alternative to measurement range calibration.


How to calibrate the transmitter’s analog output circuit using the communicator

How to perform a two-point calibration of the transmitter

How to perform a correct reset to return the transmitter calibration to its default values.

Overview

About calibration

The ST 3000 Smart Transmitter does not require recalibration at periodic intervals to maintain accuracy. If a recalibration is required, we recommend that you do a bench calibration with the transmitter removed from the process and located in a controlled environment to get the best accuracy.

Before you recalibrate the transmitter’s measurement range, you must calibrate the transmitter’s analog output signal. See Table 47 for procedure.

You can also use the communicator to reset the calibration data to default values, if they are corrupted, until the transmitter can be recalibrated. See Table 46 in this section for details.

ATTENTION

All procedures in this manual assume a transmitter poll address of 0 (zero). See page 74 for information about poll address. HART 6 transmitters have a separate menu item for switching to analog output mode.

Equipment Required

ATTENTION

Depending upon the calibration you choose, you may need any of the following test equipment to accurately calibrate the transmitter:

Digital voltmeter or milliammeter with 0.02% accuracy or better

HART hand-held communicator

Calibration-standard pressure source with a 0.02% accuracy

250 ohm resistor with 0.01% accuracy or better.


11— Calibration - Calibrating Analog Output Signal


Calibrating Analog Output Signal You can calibrate the transmitter’s analog output circuit at its 0 and 100% levels by using the transmitter in its constant-current source mode. It is not necessary to remove the transmitter from service.

The procedure in Table 47 shows the steps for calibrating the output signal for a transmitter in the analog mode.

ATTENTION

You can calculate milliamperes of current from a voltage measurement by using the following equation:

dc milliamps = 1000 x voltage

resistance

Table 47 Calibrating Output Signal for Transmitter in Analog Mode

Step Action

1 Connect communicator across loop wiring and turn it on.

See Figure 30 in Section 7 for sample test equipment hookup.

ATTENTION

Be sure the accuracy of the resistor is 0.01% or better for current measurements made by voltage drop.

Field device output 20.000 mA equal to reference meter? 1 Yes 2 No

If not equal, select No, press ENTER, then key in new meter value. (Returns to “Enter meter value” prompt until field device output equals reference meter.)

If equal, select Yes, press ENTER.

Prompt notifies you that the field device will be returned to its original output.

Calibrating Range The ST 3000 Smart Transmitter has two-point calibration. This means when you calibrate two points in the range, all the points in that range adjust to that calibration.

The procedure in Table 48 and Table 49 shows the steps for calibrating a differential pressure (DP) type transmitter to a range of 0 to 200 inH2O for example purposes. This procedure assumes that the transmitter is removed from the process and located in a controlled environment.

ATTENTION

You must have a precision pressure source with an accuracy of 0.02% or better to do a range calibration. Note that we factory calibrate ST 3000 Smart Transmitters with inches of water ranges using inches of water pressure referenced to a temperature of 39.2˚F (4˚C).

11— Calibration - Resetting Calibration


Resetting Calibration

Background

Every ST 3000 transmitter is factory-characterized. The characterization process calculates a mathematical model of the performance of the transmitter’s sensors and stores that data in the transmitter’s memory. Small residual errors result from the sensor data acquisition and modeling process. These errors can be eliminated through calibration, using either a zero offset or a span correction.

A Corrects Reset returns the zero and span calibration factors to their default values. The transmitter calculates its output based on the characterization equation alone, without any compensation for the residual errors.

A typical zero offset correction is less than 0.1 inches of water (based on a 400 inH2O range) and a typical span correction is less than 0.2% regardless of the range of calibration (down to the point where specification turndown begins). Typical performance of a 400 inH2O transmitter with Corrects Reset can be expressed as:

Accuracy = 0.2% + (0.1”/span”) • 100%

By calibrating the zero, the typical performance will be 0.2% or better.

For transmitter ranges other than 400”, the initial zero offset will be scaled by the ratio of the Upper Range Limit to 400. For example, for a 100 psi transmitter, the initial zero offset can be expressed by:

0.1” • 2768/400 = 0.7” or 0.025 psi.

Please note that these are typical values, not hard specifications.

13— Troubleshooting - Interpreting Messages


Interpreting Messages Most of the diagnostic messages that can be displayed on the communicator are listed in alphabetical order in Table 57 along with a description and suggested action to be taken.

Table 57 Diagnostic Message Interpretation Table

Message Possible Cause What to Do

Char PROM Fault Characterization PROM is not functioning correctly.

Replace meter body.

Corrects Reset All calibration “CORRECTS” were deleted and data was reset to default values.

Recalibrate transmitter. See Section 10.

DAC Diode Fault Digital to Analog Converter (DAC) fault.

Replace electronics module (PWA).

Device Disconnected Previously established communication with a transmitter has been lost. Could be a transmitter or loop failure.

Try communicating again.

Check that transmitter’s loop integrity has been maintained, that communicator is connected properly, and that loop resistance is at least 250Ω.

Electronic Fault Electronics module is not functioning properly.

Replace electronics module. Do not SAVE data.

Excess Span Corr SPAN correction factor is outside acceptable limits. Could be that transmitter was in output mode.

Check input pressure and be sure that it matches calibrated range value.

Check meter body.

Do a URV CORRECT procedure.

Excess Zero Corr ZERO correction factor is outside acceptable limits. Could be that INPUT was incorrect or transmitter was in output mode during a CORRECT procedure.

Check input pressure and be sure that it matches calibrated range value.

Check meter body.

Do an LRV CORRECT procedure.

In multidrop mode The transmitter poll address is not 0 (zero). You have tried to change the analog output of a transmitter that is in multidrop mode.

HART 5: Change “HART mode” of transmitter to analog by changing poll address to 0.

HART 6: Enable Loop Current Mode

In Output Mode Transmitter is operating as a current source.

Exit output mode (Loop test)-. Perform Master reset, (or cycle power).

13— Troubleshooting - Interpreting Messages


Message Possible Cause What to Do

Invalid Database Transmitter database was incorrect at power-up.


Verify database configuration, Manually update non-volatile memory with each parameter.

M.B. Overload

OR

Meterbody Fault

Pressure input is two times greater than URL of transmitter.

Check range and, if required, replace transmitter with one that has a wider range.

Meter body may have been damaged. Check the transmitter for accuracy and linearity. Replace meter body and recalibrate, if needed.

No DAC Temp Comp No temperature compensation data exists for calculations.

Effect will be minor degradation of ambient temperature influence specifications. Replace electronics module (PWA).

No Device Found No response from transmitter. Could be transmitter or loop failure.


Check that transmitter’s loop integrity has been maintained, that communicator is connected properly, and that loop resistance is at least 250Ω.

NOTICE: Upgrade 275/375 software to access new Xmtr functions. Continue with old description?

You have connected to a device that has a newer revision of device description than what is in the communicator.

Get updated device description for the transmitter installed in the communicator.

Note: You can continue communicating with the transmitter, but will not have access to full transmitter functions.

NVM Fault Transmitter’s nonvolatile memory fault.


HART5: PAC Fault

HART6: Flow Control Fault

Operating System Flow Control Fault

Replace electronics module (PWA)

HART5: N/A

HART6 (Advanced Diagnostics for ST 3000 Release): Operating Voltage Less Than 10V

Voltage available at the connection terminals to the device is less than 10 Volts.

Check power supply and check that transmitter’s loop integrity has been maintained and that loop resistance is at least 250Ω.

PROM Fault Transmitter Programmable Read Only Memory (PROM) fault


RAM Fault Transmitter Random Access Memory (RAM) fault.


Sensor Over Temp Meter body temperature is too high. Accuracy and life span may decrease if it remains high.

Take steps to insulate meter body from temperature source.

Suspect Input Input data seems wrong. Could be a process problem, but it could also be a meter body or PWA problem.

Put transmitter in output mode. Diagnostic messages should identify where problem is. If no other diagnostic message is given, condition is most likely meter body related.

Check installation and replace meter body if condition persists.

13— Troubleshooting - Clearing Critical Status


Clearing Critical Status After a critical failure has been diagnosed and corrected the critical status must be cleared from the transmitter. This can be done by performing a master reset using the communicator.

A master reset causes a hardware reset of the transmitter, which actually is the same as cycling the power to the transmitter.

Table 58 outlines the steps for resetting the transmitter.

Table 58 Resetting the Transmitter

Introduction

About this section

This section describes the integral smart meter options available with the ST 3000 Release 300 HARTtransmitter.

Procedures are given for setting range values of the transmitter using the smart meter pushbuttons.

You can use the meter pushbuttons or the HART communicator to set up the smart meter display to indicate transmitter PV output.

Typical smart meter indications are given as well as examples and descriptions of possible error codes displayed on the smart meter.


Appendix A— Smart Meter Reference - Introduction

Smart meter option

Depending upon your transmitter model, you can equip the ST 3000 transmitter with the Smart Meter option (option SM). This new integral smart meter is designed for ST 3000 Release 300 Transmitters and provides functionality not available with other smart meter designs.

The smart meter provides an LCD local interface that displays both analog and digital indications of the transmitter output and can be configured to display pressure in user-selected engineering units.

There are three meter option types:

Display Update Rate

Meter Display at High and Low Temperature Extremes

The rated temperature limits for the local meter are listed above and are true in that no damage to the meter will occur over these temperatures, however the readability of the LCD is affected if taken to these temperature extremes:

The LCD will turn black at some temperature between 80 to 90 C (176 and 194 F), rendering the display unreadable. This effect is only temporary, and normally occurs at 90 C (194 F).

At low temperatures, the update rate of the display is lengthened to 1.5 seconds due to the slower response time of the display. At -20 C (-4 F) the display becomes unreadable due to slow response of the LCD. This is also only temporary and normal readability will return when temperature returns above -20 C (-4 F).


Appendix A— Smart Meter Reference - Setting Range Values (Local Zero and Span)

Setting Range Values (Local Zero and Span)

Local zero and span option

ST 3000 Release 300 transmitters are available with optional local zero and span adjustments. This option is for applications that do not require a HART communicator nor digital integration with our TPS system.

About local adjustments

You must apply equivalent zero and span pressures to make the local zero and span adjustments. This is similar to LRV correct and URV set using the HART communicator. We recommend that you calibrate the transmitter before setting up the meter for custom engineering units.

The procedure in Table A-4 shows the steps for setting the range values to applied pressures using local zero and span adjustments. See Figure A-2 for typical local adjustment setup details.

ATTENTION

All procedures in this manual assume a transmitter poll address of 0 (zero). See Section 6, for information about poll address.

After making any adjustments to the smart meter, keep the transmitter powered for at least 30 seconds so that the new meter configuration is written to non-volatile memory. If power is turned off before 30 seconds, the changes may not be saved so that when the transmitter power is restored, the meter configuration will revert to the previous settings.

Table A-4 Setting Range Values Using Local Zero and Span Adjustments

Step Action

1 Turn OFF transmitter power. Loosen end-cap lock and remove end-cap from terminal block side of electronics housing.

2 Observing polarity, connect a milliammeter across positive (+) and negative (–) TEST terminals.

ATTENTION

If you have the smart meter with local zero and span adjustment option, you may use the smart meter in place of the milliammeter.

3 Loosen end-cap lock and remove end-cap from PWA side of electronics housing to expose

local zero and span assembly or smart meter with zero and span adjustments.

Step Action

4 Turn ON transmitter power and let it warm up for a few minutes. Using an accurate pressure source, apply desired zero equivalent pressure to transmitter.

ATTENTION

For differential pressure transmitters, apply pressure to the high pressure head for positive range values or vent both heads to atmosphere for zero. If zero is to equal a negative value, apply the equivalent pressure to the low pressure head. For example, if zero is to equal –10 inH2O, you would apply 10 inH2O to the low pressure head and vent the high pressure head for the zero adjustment.

5 Check that milliammeter reading is 4 mA.

If reading is less or greater than 4 mA, Then go to Step 6.

If reading is correct, go to Step 7.

ATTENTION

If you have the smart meter with local zero and span adjustment option, you may substitute the smart meter readings for the milliammeter readings. For example, with zero input pressure applied assume that the meter reads 4 inH2O instead of 0 inH2O. In this case, the meter reading is greater than 0 (or 4 mA).

6 d) Press and hold ZERO button on local zero and span assembly or smart meter.

ATTENTION

The smart meter readings revert to the default unit of percent (%) during this operation. If the error code Er0 appears on the display, you are working with a model STD110 transmitter that does not support the local zero and span adjustments.

e) Press Decrease button once to complete this function.

The smart meter display goes blank for a 1/2 second and then returns reading 0%.

f) Check that milliammeter reading equals 4 mA and release ZERO button.

ATTENTION

If milliammeter reading doesn’t change, be sure you are not working with a model STD110 transmitter that ignores local adjustments. The smart meter readings return to the set engineering units after you release the ZERO button.

If zero correction is + or – 5% of upper range limit, the CHECK STATUS indicator will be displayed. If range setting is intentional, disregard status message.

7 Using an accurate pressure source, apply pressure equivalent to desired upper range value to

transmitter.

ATTENTION

For differential pressure transmitters, apply pressure to the high pressure head and be sure that the low pressure side is vented to atmosphere.

If the applied pressure produces an output of greater than 200%, the meter display will flash O-L and the 200% value during this interim step.



Step Action

8 Check that milliammeter reading is 20 mA.

If reading is not exactly 20 mA, Then go to Step 9.

If reading is correct, go to Step 10.

ATTENTION

If you have the smart meter with local zero and span adjustment option, you may substitute the smart meter readings for the milliammeter readings. For example, with URV input pressure applied, assume that the meter reads 396 inH2O instead of 400 inH2O. In this case, the meter reading is less than 100% (or 20 mA).

9 a) Press and hold SPAN button on local zero and span assembly or smart meter.

ATTENTION

The smart meter readings revert to the default unit of percent (%) during this operation. If the error code Er0 appears on the display, you are working with a model STD110 transmitter that does not support the local zero and span adjustments.

b) Press Increase button once to complete this function.

ATTENTION

If the error code Er4 appears, you are trying to set a SPAN value that is outside acceptable limits for your transmitter. Readjust applied pressure to be within acceptable range limits and repeat this procedure. The smart meter display goes blank for a 1/2 second and then returns reading 100%.

c) Check that milliammeter reading equals 20 mA and release SPAN button.

ATTENTION

If milliammeter reading doesn’t change, be sure you are not working with a model STD110 transmitter that ignores local adjustments. The smart meter readings return to the set engineering units after you release the SPAN button.

10 Wait 30 seconds so that changes are copied to the transmitter’s non-volatile memory.

11 Remove applied pressure and turn OFF transmitter power.

12 Replace end-cap on PWA side of electronics housing and tighten lock.

13 Remove milliammeter from TEST terminals and replace end-cap and tighten lock.

14 Turn ON transmitter power and check smart meter reading, if applicable.

Figure A-2 Typical Setup for Setting Range Values Using Local Zero and Span Adjustments.

Configuring Smart Meter Using Pushbuttons The smart meter can be set to show the PV output in engineering units that are appropriate for your process application. You can select an available engineering unit or enter a custom one including upper and lower display limits settings for the smart meter’s digital readout using buttons on the face of the meter.

Using the Smart Meter

Follow these guidelines when configuring the smart meter:

If you initiate a command with the HART communicator at the same time a button is pressed on the smart meter, the smart meter will respond to the command it receives last. In other words, the last command wins.

In most cases, you can press and release a button for one-shot operation, or press and hold a button for continuous, 1/2 second, repetitive operation.

Active setup field will begin to flash at one second rate if next action is not initiated within one second. And, if no action is taken within 30 seconds, the setup function will time out and the meter will return to its previous state.



Transmitter Output Conformity and Smart Meter Configuration

Normally when using a differential type transmitter, you can select the transmitter’s output to represent a straight linear calculation or a square root calculation for flow measurement applications. This linear or square root output parameter selection is called output conformity or output form. (See Section 6 for more details on output conformity.)

When configuring the smart meter to display the transmitter output measurement, there are certain rules to keep in mind which are dependent on the output conformity selection. These rules are described in the following paragraphs.

The output conformity setting of the transmitter restricts the engineering units you can select for the smart meter display.

When the transmitter is configured for an output conformity of LINEAR, you can select only pressure type engineering units. (See Table A-5.)

When the transmitter is configured for an output conformity of SQUARE ROOT, you can select only flow type engineering units GPM and GPH.

The percent and custom engineering units can be selected regardless of output conformity configuration.

EUC mH2O †

GPM * Square Root EUD

GPH * Square Root EUE

Custom † Linear or Square Root EUF

* These selections have indicators on smart meter display. † Use stick-on labels provided for other engineering units.



Additionally, the output conformity setting restricts the setting of the lower and upper display limits to represent transmitter’s 0 to 100% output.

If you select pressure type engineering units, you cannot set the lower or upper display limits. These values are automatically set when you select the engineering units.

You can set only the upper display limit when the transmitter is configured for SQUARE ROOT output conformity. The lower display limit is fixed at zero (0) for a transmitter in square root mode and cannot be changed.

You can set both the lower and upper display limits when you have selected custom engineering units (EUF) and the transmitter output conformity is set to LINEAR.

When setting the lower and upper display limits, if you let either the lower or upper display limit setting time out (after thirty seconds), the meter will discard the newly set values and will revert to its previous settings. The meter forces you to set both limits by automatically initiating the next limit setting, either lower or upper, depending upon which limit you set first.

If you change the transmitter’s output conformity, you must reconfigure the smart meter as outlined in Tables A-6, A-7 and A-8 or Table A-9. See also “Meter/transmitter interaction” in this appendix.

Selecting Engineering Units

The procedure in Table A-6 outlines the steps for selecting the desired engineering units for a smart meter using its local adjustments on the face of the meter. You will be selecting the unit of measurement that you want the smart meter to indicate during normal operation.

WARNING

When the transmitter’s end-cap is removed, the housing is not explosionproof.

To set the lower and upper display limit values for the meter display perform the procedures in Tables A-7 and A-8. Also note that in each procedure you must:

First set the magnitude range for each display value. This enables the multiplier (K) on the display for indicating larger ranges (greater than 19999 and shifts the decimal point of the digital display left or right depending on the precision you want to show for that value).

Next set the display value. This procedure sets the display limit of the meter to represent minimum and maximum transmitter output (0% and 100 % output).

Note: Magnitude range and display values are set for both upper and lower (if applicable) display limits.

During normal operation the display range of the meter digital readout is 19,990,000 and is automatically ranged to provide the best precision possible for the digits available up to 1/100th of a unit.

ATTENTION

Please read through the entire procedure before beginning.



Setting Lower Display Values

The procedure in Table A-7 outlines the steps for setting the lower display limit to represent the 0 percent (LRV) output of the transmitter.

ATTENTION

For example purposes, the procedures in Tables A-7 and A-8 assume that the lower value is to be set at 0 and the upper value is to be set at 19,990,000 for a CUSTOM unit in a transmitter with a LINEAR output, and the transmitter’s present output is exactly 50 percent.

Setting smart meter display using the HART communicator

Using the Hart Communicator to Configure the Smart Meter Display

You can select an available engineering unit or enter a custom one including upper and lower limit settings for the smart meter’s digital readout using the HART communicator. Use the procedure in Table A-9 to setup the smart meter display with the HART communicator.

Transmitter Output Conformity and Smart Meter Configuration

Normally when using a differential type transmitter, you can select the transmitter’s output to represent a straight linear calculation or a square root calculation for flow measurement applications. This linear or square root output parameter selection is called output conformity or output form. (See Section 6 in this User manual for more details.)

When configuring the smart meter to display the transmitter output measurement, there are certain rules to keep in mind which are dependent on the output conformity selection. These rules are described in the following paragraphs. Refer to Table A-5 also for meter set up restrictions.

1. The output conformity setting of the transmitter restricts the engineering units you can select for the smart meter display.

When the transmitter is configured for an output conformity of LINEAR, you can select only pressure type engineering units. (See Table A-5.)

When the transmitter is configured for an output conformity of SQUARE ROOT, you can select only flow type engineering units GPM and GPH.

The percent (%) and custom engineering units can be selected regardless of output conformity configuration.

2. Additionally, the output conformity setting restricts the setting of the lower and upper display limits to represent transmitter’s 0 to 100% output. The table below shows the restrictions on setting display values for given engineering units and output conformity selections.

Linear No (set automatically) No (set automatically)

EU0, EUD, EUE,and EUF

Appendix C – Freeze Protection of Transmitters - Possible Solutions/Methods

Appendix C – Freeze Protection of Transmitters

Problem

When water is present in the process fluid and ambient temperatures can fall below the freezing point (32°F/0°C), pressure transmitters and their piping require freeze protection. Transmitters may also require continuous heating, if the process fluid is tar, wax, or other medium which will solidify at normal ambient. However, uncontrolled steam or electric heating, in addition to wasting energy, can cause errors and accidentally destroy the transmitter.

Possible Solutions/Methods

Solution

These two basic solutions are possible:

Eliminate the need for heating the transmitter by keeping the freezable process fluid out of direct contact with transmitter.

Control the steam or electric heat to prevent overheating on warm days while protecting against freeze-ups under the coldest conditions.

The following paragraphs in this appendix describe a number of methods for implementing both solutions.

Sealing liquid method

The simplest and least costly method is to use a sealing liquid in the transmitter meter body and its impulse piping to the process. The small contact (interface) area between the sealing liquid and the process fluid reduces the mixing of the two fluids.

You should select a sealing liquid that has a greater specific gravity than the process fluid to inhibit mixing. It also must have freezing and boiling temperatures compatible with the range of temperatures existing at the site, including the heated interface.

WARNING

The user must verify the compatibility of any sealing liquid with their process fluid.

A reliable sealing liquid is a 50/50 percent (by volume) solution of ethylene-glycol and water. This solution has a specific gravity of 1.070 at 60°F (15°C), a freezing temperature of –34°F (–36°C), and a boiling temperature of +225°F (+106°C) at atmospheric pressure. Conventional antifreeze liquids for automobile coolant systems such as Prestone and

Zerex are solutions of ethylene-glycol with some rust inhibitors and possibly leak sealants added; they may be used in place of pure ethylene-glycol.

Another sealing liquid, used in many chemical plants, is dibutylphalate an oily-type liquid with a specific gravity of 1.045 at 70°F (21°C). It has a boiling point 645°F (340°C) and does not freeze so it can be used down to about –20°F (–30°C).

Figures C-1 and C-2 show typical piping installations for this method. The process fluid must be heated above its freezing point. This is frequently done by lagging in (insulating) the connecting nipple, shut-off valve and “T” connector with the process piping. Where the process piping itself requires heating, a steam or electric trace is run around their components with consideration given to the boiling point of the sealing liquid.

Figure C-2 Piping Installation for Sealing Liquid with Specific Gravity Lighter Than Process Fluid.

The installation should be checked every 6 to 12 months to verify that the sealing liquid is at its required specific gravity.



Purging

Purging air or water purges are commonly used to prevent viscous materials from clogging the impulse lines to pressure, level, or flow transmitters. The bubbler system, using a constant-air flow regulator, is particularly common on open tank liquid level applications. No heating of impulse lines or transmitter is required, but normal precautions are required to keep water out of the air supply system.

Gas applications

We must not overlook the possibility of condensate freezing in impulse lines to transmitters measuring gas flow or pressure. Although these components could be heated similar to water and steam applications, the simplest and best approach is to install transmitters so that they are self draining. This means that the impulse lines are connected to the lowest point in the transmitter meter body and the piping is sloped downward at least one inch per foot. (Side-connected transmitters with vent-drains at a lower point in the meter body must be regularly checked to assure condensate removal.) If the transmitter is located below the process taps (not recommended), piping must still run downward from the transmitter to the drain point and then up to the process as shown in Figure C-3. Steam or electric heating of the drain point will prevent pipe rupture due to freezing.

Transmitter

Figure C-3 Piping Installation for Gas Flow.

Mechanical (diaphragm) seals

Diaphragm seals on the impulse lines provide the most expensive, yet broadest application of all the methods. Similar in principle to the liquid seals, diaphragm seals eliminate the possibility of seal liquid carry-over into the process fluid. This eliminates the need for periodic maintenance checks to assure full and equal liquid seal legs. Welded diaphragm seals with special fills permit temperatures from –34° to 600°F (–36° to 315°C) at the process interface which can therefore be steam or electrically heated to assure viscosity of tars and similar high-freezing point fluids under the coldest conditions.

You must be careful to specify large enough diaphragms to accommodate expansion and contraction of the fill fluid under varying temperatures without overextending the diaphragm into its stiff area. In general, conventional diaphragm seals are satisfactory for pressure ranges above approximately 75 psig with special large diameter elements required for low pressure or differential pressure measurements.

You can lag (insulate) impulse lines and diaphragm seals with the process piping, but this practice is only common with liquid level applications involving highly viscous materials unsuitable for 1/2-inch impulse



lines. Use a tank-mounted flanged seal in such installations. Otherwise, it is more desirable to keep the capillary lengths short, the transmitter accessible for maintenance, and (for flow applications) the normal 3-valve manifold assembly close to the transmitter for normal service checks. Thus, the impulse lines, valving and diaphragm seals with 1/2-inch connections would be electrically or steam traced, with high temperature steam permitted without damage to the transmitter. Figures C-4 and C-5 show typical piping layouts.

The impulse piping, 3-valvemanifold, and upper flangesof the metal diaphragm sealsmust be insulated and, whererequired, also heated byelectric or steam.

Electric heating

Most transmitters will withstand higher temperatures at their process interfaces (bodies) than at their electronics. Normally, it is impractical to heat transmitter bodies above 225 to 250°F (107 to 121°C) without radiant and conducted heat exceeding the rating at the electronics (normally 200°F/93°C). Prefabricated insulated enclosures with integral heating coils and thermostats set at 200°F (93°C) can assure viscosity of fluids which freeze below 180°F (82°C) while assuring safe transmitter operation. For water or similar lower-temperature mediums, the control can be set at 50°F (10°C) to save energy and call for heat only when temperature and wind conditions require.

Systems can be engineered for uncontrolled, continuous electric heating to prevent water freezing at 0°F (–18°C) and 20 mph wind velocity, while not exceeding 225°F (107°C) at the transmitter body at 90°F (32°C) ambient and zero wind velocity. The operating costs in energy for these systems usually exceed the high initial cost of the thermostat systems. Never attempt to maintain freeze points above 100°F (38°C) without thermostat controls since the Btu required to prevent freezing will normally exceed the body temperature rating under opposite extremes.

Although systems are available with hollow bolts replacing the normal transmitter body bolts and containing electrical heating elements and thermostats, certain precautions are required with such arrangements. Some transmitter meter body bolts are too small to accept the available thermostats. Also thermostat settings should not approach the body temperature limit because the heat gradient across the meter body can be such that limits are exceeded adjacent to the heating elements even when the thermostat setting is lower.

Electrical heating systems are available in explosionproof ratings for Class I, Group D, Division I and II installations.

The possibility of electric supply failure must be considered. For this reason, we recommend using alarm devices with manual acknowledgment and reset. Figures C-6 and C-7 show typical piping installations.

Steam heating

Steam heating is perhaps the most common, yet potentially the most damaging method of protecting transmitters from freeze-ups. Since steam is generated for use in the overall process operation, it is considered an available by-product. The most important point to remember when steam heating transmitter meter bodies is the temperature of the steam that will be used and its pressure. We recommend that you review the next paragraph Superheated steam considerations to get a better understanding of the temperature problem with steam heating. In brief, do not assume that 30 psig steam is 274°F (134°C) and cannot damage a transmitter rated for 250°F (121°C). With steam heating, as with electrical, you should use insulated transmitter body housing, impulse piping and valves.

It is common practice to use conventional steam traps on all steam heating systems. They permit live, superheated steam to enter the heating coils and piping down to the trap. You should also use conventional steam traps with lower pressure desuperheated steam which cannot overheat the transmitter under warm-day conditions. If the heating pipes are not carefully installed to eliminate low spots and trapped condensate in the piping, they could freeze at low temperatures.

All steam traps require a periodic maintenance program. Dirt, scale, and water softeners will cause traps to stick or jam which result in their either blowing steam continuously or not blowing steam, allowing condensate freeze-up in cold weather. When steam traps are used for cold-weather freeze protection of water lines, a thermostat controlled steam supply valve, which will shut off the steam at ambient temperatures higher than 50°F (10°C), will save steam and prevent overheating.

A more general solution is offered by a specialized type of trap which throttles condensate flow based on its temperature. This backs up hot water in the radiator within the insulated transmitter enclosure, assuring temperatures no higher than the saturated steam at the reduced pressure. Models are available to set the condensate temperature from about 70° to 200°F (21° to 93°C). They must be located within 6 to 12 inches



(15 to 30 cm) of the transmitter body and, like all steam traps, they also require periodic maintenance. The engineering of this type system is more complex than electric systems since the amount of heat loss upstream of the CTV valve under varying conditions will determine the location of the steam/water interface. It could occur within the heater coil or further up the steam line, thus affecting the heating efficiency within the insulated enclosure. Therefore, steam control of materials which freeze or become too viscous above 100°F (38°C) should probably not be attempted without some experimenting with the specific piping layout used.

Uncontrolled steam heating, even with the best pressure regulation and desuperheating of steam, should not be used to maintain transmitter temperatures above 100°F (38°C), since this type of fixed Btu input must either over or under-heat under normal ambient swings.

As with electric heating, there are many types of commercial steam heating units available such as radiant heaters, hollow meter body studs or just tubing lagged to the impulse piping and transmitter body. The same precaution applies to the use of hollow studs as on the electrical versions.

Figures C-8 and C-9 show typical piping installations. Table C-1 summarizes the temperature ranges for the various freeze protection systems.

Superheated steam considerations

We must remember that the temperature of steam is 212°F (100°C) only at the normal atmospheric pressure of about 14.7 pounds per square inch absolute (psia). If the pressure of steam is increased above 14.7 psia, the temperature of the steam is also increased. For example, if we have steam at 30 pounds per square inch gage (psig), the steam temperature is 274°F (134°C).

On industrial flow and pressure measurement applications, we may be required to use steam to heat the impulse piping to the flow or pressure transmitter, as well as the transmitter itself. For these applications, we must verify the temperature of the heating steam used. As an example, assume that steam at 100 psig saturated (338°F/170°C) is to be reduced to 30 psig pressure for the heating system. Too frequently, it is assumed that this pressure reduction will result in steam at 274°F (134°C), the temperature of saturated steam at 30 psig. Wrong! A reduction of the steam pressure will not appreciably decrease the initial steam temperature.

In our example, we were talking about saturated steam in the main header from the boiler. But modern industrial boilers cannot afford to let waste heat go up the stack. After reaching the boiling point in the drum, the steam flows through a series of pipes in the second pass of the flue gas exit, extracting additional heat energy and being raised to a temperature higher than the saturation temperature at the same pressure. This is superheat and, depending on boiler design, it may amount to 50 to 300°F (10 to 149°C) above the saturated steam temperature. It also permits packing more heat energy in a given size pipe for transmission from the process. Thus, in the typical application, the problem of steam heating is compounded by the additional superheat in the main header.

Specifically, when steam is reduced in pressure, it retains about the same latent heat or the same Btu’s/pound at the reduced pressure. Therefore, in our example, steam at 100 psig and 338°F (170°C) when reduced to 30 psig steam will have a temperature of 306°F (152°C) or a loss of only 32°F (18°C).

This steam temperature can only be reduced by using a desuperheater. This device mixes cold water with the superheated steam to reduce its temperature by removing Btu’s per pound of water (steam). It is also possible to use temperature controlled steam traps, which actually allow the steam to condense to water and therefore reduce its temperature to a pre-set value.

Table C-2 lists the various values of steam pressure, saturated steam temperatures at these pressures, degrees of superheat added to the saturated steam and finally the actual temperature of each when it is reduced to 30 psig steam.

Appendix D —Hazardous Area Classifications

Introduction

Reference information

Information is provided to clarify the Hazardous Location installation requirements in North America and internationally. An explanation of the applicable enclosure classification systems is also provided.

North American Hazardous Location Standards

NEC and CEC electrical codes

Installation of electrical apparatus within hazardous (classified) locations of the United States is conducted under the provisions of the National Electrical Code (NEC), ANSI/NFPA 70, Article 500, and within Canada under the provisions of the Canadian Electrical Code (CEC) C22.1, Part 1, Section 18.

Classes

Hazardous (classified) locations, in both the United States and Canada, are categorized into one of three classes:

Class I - Presence of flammable gases or vapors may be present in quantities sufficient to produce explosive or ignitable mixtures

Class II - Presence of combustible dusts, powders or grains

Class III - Presence of easily ignitable fibers or flyings

Divisions

The classes listed above are further categorized based upon the level of risk present:

Division 1 - Locations in which hazardous concentrations of flammable gases or vapors - or combustible dust in suspension – are continuously, intermittently or periodically present under normal operating conditions.

Division 2 - Locations in which flammable gases or vapors are present, but normally confined within closed containers or systems from which they can escape only under abnormal or fault conditions. Combustible dusts are not normally in suspension nor likely to be thrown into suspension.

Examples

Given the criteria above, the following examples are made:

Class III, Division 1 - A class III, Division 1 location is a location in which easily ignitable fibers or material processing combustible flyings are handled, manufactured or used.

Class III, Division 2 - A Class III, Division 2 location is a location in which easily ignitable fibers are stored or handled.


Appendix D —Hazardous Area Classifications - North American Hazardous Location Standards

Group classifications

Flammable gases, vapors and ignitable dusts, fibers and flyings are classified into groups according to the energy required to ignite the most easily-ignitable mixture within air. Group classifications are as follows:

Class I Group Classifications

Group A - Atmospheres containing acetylene. Group B - Atmospheres containing hydrogen, fuel and combustible process gases

containing more than 30 percent hydrogen by volume, or gases or vapors of equivalent hazard.

Group C - Atmospheres such as ethyl ether, ethylene, or gasses or vapors of equivalent hazard.

Group D - Atmospheres such as acetone, ammonia, benzene, butane, cyclopropane, ethanol, gasoline, hexane, methanol, methane, natural gas, naphtha, propane or gases or vapors of equivalent hazard.

Class II Group Classifications

Group E - Atmospheres containing combustible metal dusts including aluminum, magnesium, and their commercial alloys, and other metals of similarly hazardous characteristics.

Group F - Atmospheres containing combustible carbonaceous dusts including carbon black, charcoal, coal or other dusts that have been sensitized by other materials so that they present an explosion hazard.

Group G - Atmospheres containing combustible dusts not included in Group E or F, including flour, wood, grain, and other dusts of similarly hazardous characteristics.

Methods of protection

The following table summarizes available methods of protection for use in the given locations.

Pressurized Type Z Division 1 & 2 Keeps flammable gas out

Nonincendive NI Division 1 & 2 No arcs, sparks or hot surfaces under normal conditions



Temperature classification

Equipment intended for installation directly within the hazardous (classified) location must also be classified for the maximum surface temperature that can be generated under normal or fault conditions as referenced to either 40 °C or the maximum operating ambient of the equipment (whichever is greater). The maximum surface temperature must be less than the minimum autoignition temperature of the hazardous atmosphere present. The temperature shall be indicated in identification numbers as listed in Table D-1.

Intrinsically safe apparatus parameters

Vmax = Maximum safe voltage which can be applied to the apparatus terminals.

Imax = Maximum safe current which can be applied to the apparatus terminals.

Ci = Unprotected capacitance in the apparatus which can be considered present at the terminals.

Li = Unprotected inductance in the apparatus which can be considered present at the terminals.




Associated apparatus parameters

Isc = Maximum output current which can be delivered to the hazardous (classified) location. This current is the maximum from a single channel.

*Vt = Maximum output voltage which can be delivered to the hazardous (classified) location. This voltage is the maximum across any combination of terminals of a multiple channel configuration.

*It = Maximum output current which can be delivered to the hazardous (classified) location. This current is the maximum through any combination of terminals of a multiple channel configuration.

Ca = Maximum capacitance which can be connected to the apparatus.

La = Maximum inductance which can be connected to the apparatus.

*CSA does not recognize these parameters at this time

Entity concept

Under entity requirements, the concept allows interconnection of intrinsically safe apparatus to associated apparatus, not specifically examined in such combination. The criteria for interconnection is that the voltage (Vmax) and current (Imax), which intrinsically safe apparatus can receive and remain intrinsically safe, considering faults, must be equal to or greater than the voltage (Voc or Vt) and current (Isc or It) levels which can be delivered by the associated apparatus, considering faults and applicable factors. In addition, the maximum unprotected capacitance (Ci) and inductance (Li) of the intrinsically safe apparatus, including interconnecting wiring, must be less than or equal to the capacitance (Ca) and inductance (La) which can be safely connected to the associated apparatus. If these criteria are met, then the combination may be connected and remain intrinsically safe. Both FMRC and CSA define the entity parameters as listed in Tables D-2, D-3 and D-4 below:

International Electrotechnical Commission (IEC) Classifications

IEC Classification of hazardous locations

The IEC has established a number of recommendations applying to the construction of explosion protected electrical apparatus identified. These recommendations are found within IEC 79-0 through 79-15 and 79-28.

For all EC countries as well as various neighboring countries (CENELEC member states), the European Standards EN 50 014 to EN 50 020 and EN 50 039 apply for the construction of explosion protected electrical apparatus. They were established on the basis of the IEC Recommendations, however in comparison they are much more detailed.

Zones

Defined within IEC 7-10, Hazardous locations are categorized into three zones:

Zone 0 - Explosive gas atmosphere is present continuously, or is present for long periods.

Zone 1 - Explosive gas atmosphere is likely to occur in normal operation.

Zone 2 - Explosive gas atmosphere is not likely to occur in normal operation and, if it does occur, it will exist for a short period only.

Groups

Flammable gases, vapors and mists are classified into groups according to the energy required to ignite the most easily ignitable mixture within air. Apparatus is grouped according to the atmospheres it may be used within as follows:

Group IIC - Atmospheres containing acetylene, hydrogen, fuel and combustible process gases or vapors of equivalent hazard.

Group IIB - Atmospheres such as ethyl ether, ethylene, or gasses or vapors of equivalent hazard.

Group IIA - Atmospheres such as acetone, benzene, butane, cyclopropane, ethanol, gasoline, hexane, methanol, methane, natural gas, naphtha, propane or gases or vapors of equivalent hazard.

Appendix D —Hazardous Area Classifications - Enclosure Ratings

Enclosure Ratings

NEMA and IEC Recognition

The NEMA (National Electrical Manufacturer’s Association) enclosure classifications are recognized in the US. The IEC Publication 529 Classifications are recognized throughout Europe and those parts of the world that use the IEC standards as a basis for product certifications. The following paragraphs provide a discussion of the comparison between NEMA enclosure type numbers and IEC enclosure classification designations.

IEC Classifications

IEC Publication 529, Classification of Degrees of Protection Provided by Enclosures, provides a system for specifying the enclosures of electrical equipment on the basis of the degree of protection provided by the enclosure. IEC 529 does not specify degrees of protection against mechanical damage of equipment, risk of explosion, or conditions such as moisture (produced for example by condensation), corrosive vapors, fungus, or vermin.

IEC Designations

Basically, the IEC designation consists of the letters IP followed by two numerals. The first characteristic numeral indicates the degree of protection provided by the enclosure with respect to persons and solid foreign objects entering the enclosure. The second characteristic numeral indicates the degree of protection provided by the enclosure with respect to the harmful ingress of water.

NEMA Standards

NEMA Standards Publication 250, Enclosures for Electrical Equipment (1000 Volts Maximum), does test for environmental conditions such as corrosion, rust, icing, oil, and coolants. For this reason, and because the tests and evaluations for other characteristics are not identical, the IEC enclosure classification designations cannot be exactly equated with NEMA enclosure type numbers.

Table D-4 provides an approximate conversion from NEMA enclosure type numbers to IEC enclosure classification designations. The NEMA types meet or exceed the test requirements for the associated IEC classifications; for this reason the Table cannot be used to convert from IEC classifications to NEMA types.

Annunciation of a primary seal failure per ANSI/ISA–12.27.01 is electronic and is displayed in various forms based on the type of communication used for the particular transmitter. Failure of the primary seal is considered a Critical Failure. Based on testing annunciation of primary seal failure will occur in 7 hours or less.

The transmitter’s 4-20 mA output will be driven to the selected failsafe direction – upscale or downscale.

The transmitter’s digital output (DE, HART, Fieldbus) will display any of the following responses which could indicate a primary seal failure as well as other meter body faults.
