3 Overview

This chapter explains the principle functions of the DISOCONT Tersus system used in conjunction with a Stock

coal feeder.

3.1 What is the DISOCONT Tersus/DT-9?

The DISOCONT Tersus is a versatile family of modular weighing electronics for use with weighing and feeding

systems.

The DISOCONT Tersus performs all weighing and processing functions required for the measuring and feeding

of bulk solids. It is designed for continuous measuring and control tasks as well as discontinuous batching.

Used in conjunction with the specific application software for weighing and feeding tasks, the DISOCONT Tersus

can be used in the following industries:

Power

Steel

Basic Materials

Cement

Food

Chemical.

In connection with the corresponding mechanical equipment, the following systems are supported:

Belt Scales

Weigh Feeders

Solids flow meters (chutes) Solids flow feeders

Loss-in-weight, gain-in-weight feeders

Mass flow meters (Coriolis meters)

Mass flow feeders (Coriolis feeders)

Filling systems.

The Stock DT-9 configuration of the DISOCONT Tersus is a modified version, optimized for feeding coal in pow-

er plant environment. There are two different versions of the DT-9. One is a completely redesigned and updated

version that is used in new installations. The second one uses the same components and software but has been

optimized for use as an upgrade to existing Stock 8085, 196, and 196NT installations. This version uses the

196NT connectors and mounting footprint.

VCU 20103Designed for new installations where backwards compatibility is not required. This version is iden-

tified by the steel mounting frame and screw type electrical connectors. A Touch Screen HMI is always used

when a VCU 20103 is installed.

VCU 20104Designed as a drop in replacement for the 196NT in existing installations. This version is identified

by the brown Amp style electrical connectors. The VCU 20104 can be used with either a Touch Screen HMI or

with an existing 196NT display.

3.3 Measuring PrincipleThe belt weighing system is designed to continuously weigh the amount of material transported on the feeder

belt. The actual weight of material transported is calculated by multiplying the feeder belt load, in lbs/inch, times

the feeder belt speed. The systems used to measure these two values are described below.

Belt Load

The feeder weight signal is generated by two load cells that support a single weigh roller. Two weigh span rollers

are located on each side of the weigh roller to accurately define the length of belt (and amount of coal) being

supported by the weigh roller.

Since the load cells only support half of the weight on the weigh span (each load cell supports 25 percent of thetotal weight) the effective platform length (Leff) is calculated as:

Leff = Lg / 2

Leff = Effective platform length

Lg = Total platform length

Overview



BV-H6411GB, 1221

- 11 -

The microprocessor computes the feeder belt load by repeatedly reading the voltage signal from each load cell

and converting the signal into a digital value (binary number) using an analog to digital (A/D) converter. Each

value is then compared to parameters stored in permanent memory to determine if the signal is within accepta-

ble limits, and if it is, it is stored for use. The same operation is then performed on the other load cell, and the

signals are compared to each other to test their validity. If the signals are determined to be invalid, the feeder is

switched to volumetric operation and the controller uses a simulated belt load calculated from an historical aver-

age stored in memory. If the signals are determined to be valid, the two load cell signals are summed, the tare is

subtracted and the result is multiplied by a scaling factor based on the load cell data specified in P04.01 LC

Characteristic Value and P04.02 LC Rated Capacity to determine the nominal weight of material on the belt. This

nominal value is then multiplied by the three range correction factors (P10.03, P10.04 and P10.05) to determine

the actual weight (QB).

The belt load (Q) is computed from the total weight (QB) as follows:

Q = QB / Leff

Q = Belt load in kg/m

QB = Weight of load on platform in kg

Note: The 196NT parameter 10 Weigh Span Length is the full distance between the two weigh span rollers. The

DT-9 parameter P04.03 Effective Platform Length is half the distance between the two weigh span rollers. For

any given feeder, the value used by the DT-9 should be one half of the value used by the 196NT.

Belt Speed

During normal feeder operation, the belt speed is calculated from the motor RPM rather then being measured

directly. The relation ship between motor speed and belt speed is determined during calibration and is displayed

as P10.02 Pulses per length.

Feedrate Control and Totals

The weigh and speed information is used to calculate the actual feedrate as shown.

Feedrate (I) = Belt load (Q) x Belt Speed (V)

The feeder control accepts a feedrate set point from the source selected using parameter P03.02 Feedrate Set-

point . This signal is compared with a computed feedrate derived from measured weight and speed signals to

generate the system error signal which is used to adjust the speed of the motor. Compensation for system stabil-

ity is provided in the software using parameters P11.01 P-Component KP and P11.02 I-Component TN. These


33/458

Overview

BV-H6411GB, 1221

- 12 -



calculations are repeated periodically and at each iteration, the actual feedrate is multiplied by the time interval

to calculate the totalizer increment. Separate totals are kept for gravimetric and volumetric operation.

3.4 Operating Modes - Remote

The Remote Operating Mode is provided for normal operation, with the feeder feeding coal under control of the

plant control system. The source for the Start/Stop signal is designated by P03.01Feeder Start and the source

for the feedrate setpoint is designated by P03.02 Feedrate Setpoint. Analog feedback signals are generated

based on the entries to parameter block 14 Analog Outputs. Digital feedback signals (relay outputs) are generat-

ed based on the entries to parameter block 16 Digital Outputs.

While in the Remote Operating Mode, the feeder can use one of three systems to generate the required belt

speed set point.

Details for the different modes can be found in the appendix.

3.4.1 Gravimetric

Gravimetric Mode is the normal mode of operation. The feed rate is calculated using the belt speed and the ac-

tual belt load, and is controlled by the feed rate demand signal supplied by the plant control system. Parameter

P03.05 Maximum Feedrate, corresponds to the maximum demand signal and the minimum feed rate is set by

parameter P03.06 Minimum Feedrate. Parameter P02.05 Nominal Flow Rate should always match parameter

P03.05 Maximum Feedrate. The system can be set to produce an error if the demand signal is outside to normal

range.

3.4.2 Volumetric

Volumetric Mode is used when an error is detected in the weighing system. The actual feed rate is calculated

using the belt speed and an assumed belt load based on the average value over the last several hours, and is

controlled by the feed rate demand signal supplied by the plant control system. Parameter P03.05 Maximum

Feedrate, corresponds to the maximum demand signal and the minimum federate is set by parameter P03.06

Minimum Feedrate. Parameter P02.05 Nominal Flow Rate should always match parameter P03.05 Maximum

Feedrate. The system can be set to produce an error if the demand signal is outside to normal range.

3.4.3 Volumetric Control

Volumetric Control Mode is a variation of the gravimetric mode that is used when the feeder weigh system is

working correctly but the material on belt switch indicates that the belt is empty. The displayed feedrate and the

customer feedback signal is still based on the actual material being fed and the gravimetric total is still beingincremented but the belt speed is determined as if the feeder were in volumetric mode. This mode is used to

prevent the feeder from running to maximum belt speed when material flow is lost.

3.5 Operating ModesOFF/Maintenance

The OFF/Maint mode is is provided so that the feeder can be isolated from the plant control system during

startup, calibration and other maintenance operations. In this operating mode, the plant start/stop and demand


34/458

Overview



BV-H6411GB, 1221

- 13 -

signals are ignored and feedback signals are not generated. The feeder must be in OFF/Maint mode before a

system calibration can be performed. When the feeder is operated in the OFF/Maint mode, the belt speed is set

based on the value of parameter P02.16 Maintenance Speed. This is an open loop signal calculated as a per-

centage of the full scale signal to the motor speed control (see parameters P11.04 Lower Limit, P11.05 Upper

Limit and P01.06 Controller Magnitude Offset).

In OFF/Maint mode belt can be started via the buttons on the VHM, via the Local key on the 196NT keyboard or

a digital input as defined by P15.25 DI: Local Start .

4 DT-9 Setup

This section describes the startup process when a new feeder is installed or when an existing DT-9 is replaced.

CAUTION

Installing the DT-9 in a feeder that uses the Stock Load Cell Amplifier

Installing the DT-9 in a feeder that uses the Stock Load Cell Amplifier will dam-

age the DT-9. The old style Load Cell Amplifier must be replaced with the new

version before the DT-9 can be used.

CAUTIONDO NOT connect a normal Ethernet cable to X96 (red RJ45 connector).

This connector uses normally unused wires in the CAT 5 cable to provide power

to the touch screen display. Failure to follow this warning may result in damage

to the DT-9 or to the attached network device.

HINT

The weigh span is specified using parameter P04.03 Effective Platform

Length.

This parameter is the distance between the weigh roller and either one of theweigh span rollers. This is one-half the value used by the 196NT, which is the

distance between the weigh span rollers.

4.1 Setup Notes

This section is a general description of the feeder setup process. This process can be performed using either

the touch screen HMI or a PC loaded with the EasyServe software. Section Operation Using the Touch

Screen HMI [ 39] describes the Touch Screen HMI and Section Operation Using EasyServe [ 49] de-

scribes EasyServe.

Events (Error conditions) are usually defined using three parameters. The first, which is usually hidden by

default, defines the input signal that initiates the event, the second specifies the delay between the time

when the error is detected and the time when the event is generated, and the third, specifies the type of

event that is generated (A, W1, W2 or IG). In most cases, the Event (error) can be disabled by setting the

type of event to IG.

The DT-9 has 15 digital inputs (DI 1 through DI 15) and 13 digital outputs (DO 1 through DO 13). Each is

assigned to a specific function, and wired to the appropriate external device. These assignments are hidden

and should not be changed. See chapter Default I/O Pointsfor a list of the default assignments.


37/458

DT-9 Setup

BV-H6411GB, 1221

- 16 -



The DT-9 has one analog input (AI 1) and two analog outputs (AO 1 and AO 2). AI 1 is normally used as the

customer demand signal, AO 1 is normally used to control the motor speed control and AO 2 is normally

used as the customer feedback signal. These assignments are hidden and should not be changed.

The DT-9 has four slots for auxiliary analog I/O cards (channels A10-A13). These channels are not normallyused. Contact Stock engineering if special analog I/O signals are required.

4.2 Startup and Functional Check

This procedure verifies that the feeder and its controls are operating properly, simulates feeder trip conditions,

and checks the principal input/output connections.

1. Apply power to the feeder.

2. Insure that the feeder is in OFF/Maint mode and that the touch screen HMI is set to the home screen.

3. Set the feeder parameters as described in section Setup Parameters [17].

4. Interpret event messages, if any, and correct faults.

5. Unbalance the load cells by engaging the calibration weight on one side of the weigh roller. The display

should indicate volumetric mode. Unbalance each load cell in order to check both sides, then remove the

calibration weight(s).

6. Press and maintain the Jog>> button to verify that belt travel is in the in correct direction.

7. Run the feeder in LOCAL mode by pressing the Run>> button. The feeder will operate at the maintenance

speed programmed in P02.16 Maintenance Speed. Check the motor speed for stability.

8. Run the feeder in LOCAL by pressing the Run>> button. Set the Belt Drive Motor (Run Enable) switch to the

STOP position. The feeder should stop and the display should show a IL01 Event: Run Disabled error mes-

sage. Acknowledge the event and return the Belt Drive Motor switch to its normal position.

9. Stop the feeder and deflect the material-on-belt limit switch paddle to simulate a loaded belt. Run the feeder

in the LOCAL mode to verify that the feeder trips. If it does not, check the adjustment of the paddle switch

cams.

10. Check the event display or the event line on EasyServe. They should both show a WM12 Event: Coal on

Beltalarm message with a time stamp. Acknowledge the event and return the coal-on-belt paddle to its nor-

mal position

11. Calibrate the feeder as described in section Calibration [20].

12. Align the analog inputs and outputs as described in section Analog Trim Function [27].

13. Hang the calibration weights. Produce or simulate a feeder start permissive. Check feedrate and feedback

linearity by applying demand signals of 100, 75, 50, and 25 percent. Compare each demand signal applied

to the feedback signal output. Compare the demand feedrate setpoint (service value 4) with the measured

feed rate of the feeder for each signal.

14. Energize the feeder in the REMOTE mode and deflect the discharge pluggage alarm (or touch the discharge

pluggage sensor with a metal rod). After the preset delay in P15.10, the feeder should be de-energized. If

the feeder does not trip, check the adjustment of the cams for the paddle switch or the sensitivity setting of

the sensor according to the procedure in the original equipment manual.


38/458

15. Check the event display or the event line on EasyServe. They should both show a WM07 Event: Discharge

Pluggage alarm with a time stamp. Acknowledge the event and return the discharge switch to its original

state.

16. Return the feeder to REMOTE operation.

4.3 Setup Parameters

The microprocessor controller is tailored to specific feeders and customers needs by the setup parameters.

Feeder-specific physical dimensions must be entered as well as user-selectable display modes and set points.

These values are stored in permanent memory and are only entered once. See section Parameters [ 59] for a

complete list and description of the parameters.

Note: In any given application, the majority of the DT-9 parameters are either not used, or fixed by the design of

the feeder and cabinet. These parameters can be viewed using EasyServe in expert mode (default password

7353) but should not be changed.

The controllers will come preprogrammed from Stock Equipment Company but if changes are needed, there aretwo ways to do this:

Using EasyServe Software (See section Parameters [59])

Using the Touch Screen HMI (See Section The 'Setup' Screen [42])

4.3.1 Commonly Changed Parameters

The following is a list of parameters that are commonly changed during startup. Their values should be recordedfor future reference. See section Parameters [ 59] for a complete list and detailed descriptions.

P-No. P-Name Actual

The following parameters set the feedrate associated with a 100 % demand signal (usually 20 mA). They must

always be set to the same value. See project specific documentation for the correct value.

P02.05 Nominal Flow Rate

P03.05 Maximum Feedrate

The following parameter is the belt speed associated with the nominal (maximum) feedrate and the nominal

material density. It is calculated as:

P02.05 Nominal Flow Rate) / (300 X Nom. Density X P04.10 Load cross section

Inputs are in lbs/hour, lbs/cubic ft and square feet. Results are in inches/sec.

P02.06 Nominal Speed

The following parameter sets the minimum feedrate clamp. See project specific documentation for the correct

value.

The following parameter selects the text string displayed on the top line of the touch screen HMI.

P02.03 Scale Name

The following parameters select the units and formats that are used to display the various feeder information on

the display.

P02.01 Language

P02.02 Units

P02.07 Display Formats

P02.08 Flow Rate Units

P02.09 Counter 1 Unit



The following parameter selects the demand signal to the motor speed control when the feeder is running in

local mode. It is normally set to 50 %.

P02.16 Maintenance Speed %

The following parameter specifies the length of belt that is supported by the load cells. It must be set to the dis-

tance between the first weigh span roller and the central weigh roller (one half the distance between the weigh

span rollers). See project specific documentation for the correct value.

P04.03 Effective Platform Length

The following parameter specifies the characteristics of the motor tachometer. See project specific documentati-

on for the correct value.

P04.09 Tachometer: Pulses per Rev P/rev

The following parameter specifies the area under the leveling bar. See project specific documentation for the

correct value.

P04.10 Load cross section

P07.02 sets the maximum time between Belt Motion Monitor (BMM) pluses and P07.03 selects the type of event

that is generated when this limit is exceeded. Set P07.03 to IG if a BMM is not installed. See project specific

documentation for the correct values.

P07.03 Event: Belt Motion Monitor A / W1 / W2 / IG

The following parameter specifies the distance between the calibration probe bosses. See project specific

documentation for the correct value.

P10.01 Calibration Probe Span

The following parameter specifies the actual value of the calibration weigh. This value is stamped on the weight.

P10.08 Calibration Weight

The following parameters specify the cleanout conveyor duty cycle. Set P13.02 to zero to run the cleanout con-

veyor continuously.

P13.02 CleanOut ON Time Hours

P13.03 CleanOut OFF Time Hours

The following parameters control the Loss of Material on Beltevent. Setting P05.14 to A causes the feeder trip

(stop the feeder) when the coal on belt signal is lost during normal operation. Setting P05.14 to W1 or W2 will

produce a warning. P05.13 sets the delay between the time that the signal is lost and the time that the event is

generated (This is normally set to one second). Set P05.14 to IG to disable this feature.

P15.13 Loss of Flow Trip Delay

P15.14 Event: Loss of material A / W1 / W2 / IG

The following parameters are used to control the Level/Temperature Sensor event. The Level/Temperature

Sensor input is normally connected to either a flow monitor in the downspout or a temperature switch at the

feeder discharge. Setting P15.21 to A causes the feeder trip (stop the feeder) when the coal flow monitor indi-

cates a loss of flow in the downspout. Setting P15.21 to W1 or W2 will produce a warning. P15.20 sets the delay

between the time that the signal is detected and the time that the event is generated. Set P15.20 to 100 lbs for a

quick response. Set P15.21 to IG to disable this feature. See project specific documentation for the correct valu-

e.

P15.20 Level/Temperatur Sensor Delay

P15.21 Event: Coal Flow A / W1 / W2 / IG

The following parameters specify the Ethernet communications address. The default values should not be

changed unless the DT-9 is connected to a local network.
