The first entry of the IVT model code designates the electrical standard used. a) Equipment designed to the North American standards is compliant with Article 501 and

505 of the National Electrical Code (NEC) and has been evaluated by Underwriters Laboratories. The NEC version of the LubriMist® Model IVT has a UL/CUL Listing to Class I, Division 2, Groups B, C, D temperature code T4 and alternately Class I, Zone 2, Group IIB + H2, T4

b) Where electrical installations require European standards, the LubriMist® Model IVT Oil Mist Generator is available to ATEX II 3G EEx nC IIC T4.

• Inlet Power: The LubriMist® Model is available for connection to either 115 or 230 VAC single-phase power. The purchaser specifies supply voltage. Refer to the model code sheets for options available for specific voltages and construction.

• Labeling: Designates the language used in the operator interface to display messages.

• Oil Reclamation: For installations using the patented LubriMist® Closed Loop Oil Mist Systems. The oil reclamation option includes equipment to reclaim the oil from the return mist header when closed loop technologies are used. The Oil Mist Reclamation option includes a motor driven centrifugal coalescer to strip the oil from the return mist stream. A pneumatic driven pump returns the collected oil into the IVT Oil Mist Generator bulk supply reservoir. A high-level alarm switch is provided. For a complete description see Optional Equipment under the PRODUCT DESCRIPTION section of this manual. • Cabinet Accessories: Several accessories are available when certain environmental and ambient conditions can be expected. These options are recommended where aggressive or extreme site conditions exist. The options are designed to improve operational reliability and reduce long term maintenance. Cold and warm ambient options are available for locations where extremely hot or cold ambient temperature may be encountered. Air purging is recommended where extremely corrosive atmospheres may be encountered. For a complete description see Optional Equipment under the PRODUCT DESCRIPTION section of this manual.

Mist Outlet Valve Assembly The oil mist-generating head uses compressed air to produce a small droplet of oil (1-3 micron). The oil droplets are suspended in the air and are discharged into a distribution-piping network. The piping system then supplies the oil mist to user machinery for bearing lubrication. A specially designed outlet-switching valve controls the flow of mist out of the IVT. The switching valve is pneumatically controlled. As the air supply to either mist head is opened to supply air to its associated mist-generating head, main or auxiliary, the switching valve automatically closes the outlet of the unused generator and opens the outlet of the one being used to generate the oil mist. The generated oil mist exits the top of the IVT cabinet through a 2” pipe. The mist outlet pipe is sealed as it exits the top of the IVT cabinet.

Air Heater Control and Cutout Sensors

The heater manifold extends into the oil reservoir to a point below the oil level. As oil is drawn into the mist generator head, the oil passes through a drilled port in the heater manifold. In this manor, the air heater element not only heats the air, but also heats the oil being generated into oil mist. A type K thermocouple senses the air temperature as it enters the mist generator to provide the temperature control and high – low alarm signal. A second type K thermocouple is installed in the air stream as it exits the air/oil heater manifold to function as a high temperature heater cutout. The IVT controller maintains the air temperature of the main oil mist generator. The controller produces a DC voltage output signal to control a solid state non-arcing relay for switching power to the heater element. A separate controller and solid state relay is used for controlling temperature for the auxiliary unit. The heater element is interlocked through the IVT controller with the low air pressure alarm. The heater is inoperable if the regulated air pressure is set lower than the low alarm set-point. This ensures that air is flowing over the element before power is applied.

Oil Supply Transfer Pump and Control The IVT Oil Mist Generator has a maximum bulk oil reserve capacity of approximately 75 gallons (US) / 284 liters. A pneumatically operated pump transfers the oil from the bulk compartment to the main or auxiliary mist generator reservoir as need. Control for the main oil mist generator is maintained automatically. As oil mist is generated and dispensed out of the IVT, the oil level in the mist generating reservoir drops. The IVT controller receives a signal from a level switch when oil level drops to a determined level. The controller then energizes a DC voltage solenoid operated air valve, which in turn starts the pump. The pump fills the reservoir until the switch contacts signal the controller to de-energize the air solenoid valve. The oil level switch assembly has a second level switch contact to provide a low level alarm signal. Both switches are hermetically sealed reed switches. An interlock is provided through the IVT controller that makes the air heater element inoperable while a low-level alarm is active. The switch assembly mounts through the top of the reservoir. The oil level for the auxiliary unit is manually maintained.

Main Oil Mist Generator Controller

The IVT Oil Mist Generator includes instrumentation to monitor its operation. The operation of the main oil mist generator and the auxiliary oil mist generator are independent, and are energized through separate disconnect switches. In the main oil mist generator ten process variables are monitored. If any monitored variable exceeds a predetermined high limit, or decreases below a predetermined low limit, a fault signal is provided. The monitored operating variables are: • Incoming Supply Air Pressure • Regulated Air Supply Pressure (Main Oil Mist Generator Head) • Air Temperature (Air / Oil Heater In The Main Mist Generator Head) • Oil Supply Pressure (When Oil Pump “On” To Verify Operation) • Bulk Oil Reservoir Oil Level • Bulk Oil Reservoir Oil Temperature • Mist Header Pressure • Mist Density • Low Oil Level (Main Oil Mist Generator Supply) • Ambient Temperature (No alarms are associated with the Ambient Temperature Sensor)

The IVT solid-state controller provides all monitoring and control functions. Segregation of power voltage (>30 VAC / 60 VDC) and control voltage (<30 VAC / 60 VDC) is provided by separate enclosures. All components in the power voltage enclosure are none arcing. The enclosure is a stainless steel NEMA type 12 enclosure. Power connections for the air/oil heater element and the red and green status lights are made in the power voltage enclosure. Both circuits are fused. Power to the heater is switched on/off using a non-arcing solid state relay. Switching between the red and green status lights is done using a relay with hermetically sealed contacts. A transformer located in the power voltage enclosure provides 24VAC supply to the low voltage controller. The control voltage enclosure contains microprocessor controlled P/C circuitry for polling the input signals of all peripheral sensors, transmitters and thermocouples. The input signals are interpreted by the microprocessor to perform control and alarm function for the IVT Oil Mist Generator. User accessible keypad and liquid crystal displays are accessible from the front operator compartment. All circuits in and connected to the control voltage enclosure are non-incendive.

Bulk Oil Reservoir Level Transmitter The oil level in the bulk supply reservoir is gauged using a level transmitter. The transmitter consists of a 316SS float that travels the length of the sensor tube. The sensor tube houses a circuit string of resistors and magnetically operated reed switches. There is a switch and resistor every ½ inch along the length of the tube. The circuit containing the resistors and switches is the same length as the measured range. As the level inside the reservoir varies, the magnetic float moves up or down the tube. When oil is added to the reservoir the float rises to the top of the stem. The float moves down the stem as oil is consumed. As the float moves, switches open/close thereby changing the resistance in the circuit. The two-wire transmitter converts this resistance change to a 4-20 mA current signal corresponding to fluid level. Resolution of the transmitter is ½ inch (proportional to the spacing of the sensor switches). The level transmitter is connected to the IVT controller with a flexible cord. Through the controller, the level transmitter monitors the level in the bulk oil reservoir and gives a high and low level alarm.

Mist Pressure Transducer A solid state pressure transducer is used to monitor the pressure of the mist distribution system. This variable is referred to as Mist Pressure. The mist pressure transducer is mounted on top of the bulk supply reservoir. It is a two-wire 4-20 mA output pressure transducer. The mist pressure transducer is connected to the IVT controller with a flexible cord. Through the controller, the transducer monitors the mist header pressure and gives a high and low alarm signal.

Bulk Oil Reservoir Oil Temperature Sensor A type K thermocouple monitors the temperature in the bulk oil reservoir. The thermocouple connects to the IVT controller with a flexible cord and monitors the oil temperature in the bulk oil reservoir. High and low alarms are active when the oil temperature is not within a prescribed operating range.

Mist Density Sensor The LubriMist® monitor is a proprietary sensor manufactured by Lubrication Systems Company. The mist monitor is a solid state device that detects fluctuations in oil mist density. The LubriMist® oil mist monitors user selectable sensitivity adjustment provides continuous on-line monitoring of the oil mist density in the supply header, allowing oil mist users to optimize oil consumption without over or under lubricating machinery. Continuous monitoring is accomplished through the IVT controller. Once the oil mist flow reaches the detector, the LubriMist® monitor will automatically respond to changes in oil / air ratio. In operating the LubriMist® monitor, it is important to understand that although any given out-put reading may correspond to a quantitative oil/air ratio, the LubriMist® monitor does not make a mass measurement of the amount of oil suspended in the air. The out-put signal range of 0-100 percent mist density, represents a change in the ability of a light beam to penetrate the oil mist sample as it passes between a light source and a light detector. A mist density reading of zero indicates that no or a very small amount of oil mist is present, thereby allowing the light to easily reach the photo detector. As the oil/air ratio increases, the small oil particles reflect and block the light from the detector causing a change in the mist density reading. When the light can no longer penetrate the photo optical bench, the LubriMist® monitor reads 100%. The LubriMist® monitor is designed to detect and respond to changes in oil/air ratio. The LubriMist® monitor is connected to the controller with a flexible cord. Alarms for high and low mist density annunciate when the monitor detects an opacity reading outside of preset operating set-points.

Oil Supply Pressure Transducer A solid state pressure transducer is used to monitor the operation of the oil transfer pump when the automatic oil fill feature is energized (see Oil Supply). When the level switch in the main oil mist generator reservoir initiates the fill cycle, the pressure transducer confirms that pump operation has started. When the oil transfer pump is cycling, its operation is monitored. The oil pressure transducer is mounted in a manifold at the oil pump outlet. It is a two-wire 4-20 mA output pressure transducer. The oil pressure transducer is connected to the IVT controller with a flexible cord. Through the controller, the transducer monitors the oil pressure when the auto fill sequence is active and gives a high and low level alarm. If a pressure alarm is detected, the alarm remains active after the fill cycle is complete.

Auxiliary Oil Mist Generator

The IVT includes an auxiliary or spare oil mist generator. The auxiliary unit is provided for use when maintenance or repair operations are being performed on the main oil mist generator. A power switch is located in the operator panel for removing electrical power to the auxiliary unit when it is not in service. The auxiliary unit is equipped with a mist generating head with air / oil heater (see Mist Generating Head With Air/Oil Heater). A type k thermocouple and a solid state PID type controller provide heater control. A second type k thermocouple connected to the controller is used for high temperature alarm and cutout. The fused input AC voltage is connected to a local terminal strip in a NEMA 12 electrical enclosure. Distribution from the terminal strip is made to power the controller and heater element. The controller produces a DC voltage output signal to a solid state non-arcing relay for switching power to the heater element. A second solid state relay is wired to open the air heater element supply power if the controller detects a high temperature condition. An alarm indicator on the operator interface of the controller indicates when an alarm condition has been detected. Acknowledgment of the alarm is required before heater operation is resumed. The heater element on the auxiliary unit is interlocked with a low air pressure switch. The heater is inoperable if a low regulated air pressure condition exists. This ensures that airflow is established before power is applied to the element. The low air pressure switch is explosion proof.

Oil Mist Reclamation The Oil Mist Reclamation option is used when LubriMist® Closed Loop Oil Mist systems are being installed. LubriMist® Closed Loop Oil Mist Systems uses the same principles to apply oil mist for machinery lubrication as non-closed loop oil mist systems. However when closed loop systems are installed, after the oil mist has been applied, the oil is continually reclaimed for reapplication to the serviced rotating machinery. As the oil mist flows through the rotating equipment bearings and bearing housings, a part of the oil mist coalesces into liquid oil. A lesser amount of oil remains suspended in the air as it vents from the bearing housing. This is often referred to as Stray Mist. User equipment items are equipped with oil collection containers to collect the liquid oil that is manually pumped into the return mist header. The stray mist is collected into a return mist header as it vents from the bearing housing. The return mist header is connected to the Oil Mist Reclamation Unit.

An oil over flow connection is located on the right side of the reservoir. This connection allows oil to be drained away should the reservoir be overfilled. It is located above the high-level switch position. The Oil Mist Reclamation unit is a self-contained unit that mounts onto the rear of the IVT Oil Mist Generator cabinet. The returning stray mist is stripped of its oil by an electric motor driven rotating coalescer. The returning air is vented from the unit to atmosphere. The coalesced oil is collected in an integral receiving reservoir. A pneumatic driven transfer pump transfers the liquid oil to the IVT bulk oil reservoir for reuse. The reservoir is equipped with a liquid level gauge to monitor the oil level in the reservoir. A bulls-eye sight glass is located at the reservoir bottom to check for contamination. A high-level alarm switch interlocks with the controller in the IVT main oil mist generator to provide a system alarm. A separate output signal is provided to interlock with the motor driver control circuit.

Bulk Oil Supply The LubriMist® IVT Oil Mist Generator has an integral 75-gallon oil supply reservoir. Prior to commissioning the system, the bulk oil reservoir must be charged with a fresh clean supply of oil. Oil may be pumped directly from drums or other bulk supply source through a supply hose. A clean 10-micron (nominal) oil filter should be used while filling the bulk supply reservoir. To fill the reservoir, follow these steps. Reference the diagram on the next page for clarification. 1) Fill the bulk oil reservoir

a) Open the operator compartment door. Verify that the Drain valves for the bulk oil reservoir, the main oil mist generator reservoir and the auxiliary oil mist generator are in the closed position. Valves are closed when their handles are rotated to the full clock-wise position. Valves should have drain plugs installed and secure.

b) Locate the bulk oil reservoir fill cap. The cap is located to the right of the spin-on oil filter. Loosen and unscrew the oil fill cap and set aside. Note that the cap is connected to the reservoir with a chain to discourage misplacing.

c) Check the end of the oil fill hose for contamination. Clean away any dirt and grit that may be in or on the hose end nozzle. Insert the hose into the fill connection and fill the reservoir. Initial fill should be a minimum of 55-gallon drum.

IF more than one 55-gallon drum of oil is used to fill the bulk oil supply reservoir, monitor the oil level gauge. DO NOT OVER FILL.

The reservoir will hold approximately 75 gallons maximum. Overfilling will result in oil overflowing out of the fill connection and onto the ground.

WARNING

d) Once filling is complete, remove the oil supply hose and reinstall the oil fill cap. The cap

is threaded and seals with an o-ring. Care should be taken to ensure proper thread alignment and engagement. The cap needs only to be firmly tightened by hand. The oil hose should be wiped clean and stored in a manor to avoid contamination. It will be needed in the future for refilling the oil reservoir.

Do not use pliers or any other hand tool to grip and tighten the oil fill cap. Tighten hand tight. DO NOT OVER TIGHTEN.

2) Prime the oil transfer pump. The oil transfer pump is pneumatically operated and must be

primed with oil. Before priming the pump check the spin on oil filter to ensure that it is tight. a) To prime the oil transfer pump, open the air supply valve (center) by turning the handle to

the full clock-wise position. b) Hold the air toggle valve in the OPEN position and adjust the air pressure regulator to

start the pump. The center regulator supplies air pressure to the oil transfer pump. As the air pressure increases the oil transfer pump will start to operate. The pumps operation will produce a “clicking” sound from within the IVT’s mechanical compartment. Once the pump is primed the cycle rate will suddenly decrease and slow down.

c) Once the pump has primed, hold down the air toggle valve and while adjusting the air pressure regulator, set the pump cycle speed between 160 and 200 cycles per minute. Maximum oil fill rate to the main oil mist generator is at 200 cycles per minute. Once the pump speed has been set, release the air toggle valve, leaving the air pressure setting as is.

Do not exceed 200 cycles per minute while priming or performing final adjustment of the pump speed. The maximum continuous pump speed is 200 cycles per minute. Over speed may damage the pump.

Starting The Model IVT Oil Mist Generator CAUTION: For IVT Oil Mist Generators equipped with either the Warm Ambient Option (Cabinet cooling) or Cold Ambient Option (Air Preheating and Cabinet Heating) or the for ATEX constructions, refer to the respective start-up instruction prior to starting the IVT Oil Mist Generator. The interior of the cabinet must be conditioned prior to energizing the IVT Oil Mist Generator.

Prior to start-up recheck all connections and insure that all fittings are tight and electrical connections are properly made. Insure that the oil mist distribution system, reclassifies and application point connections, vents and drains are properly installed. Verify that the equipment and systems used to maintain the air supply is in proper working order and that these supplies are turned on at the unit air inlet connection. The LubriMist® Model "IVT" oil mist generator features a programmable solid state controller that monitors and controls operating variables. Pre-set factory values are preprogrammed and installed into the system both for control and alarm set points. No adjustments to the factory set points are necessary during start-up. See Reading Alarm And Control Set Points in the section titled OPERATING GUIDE for a listing of the factory default values for each operating variables. Start-up of the LubriMist® Model IVT is very simple and requires only a few operator initiated actions. The steps for starting-up of the Model IVT oil mist generator are: 1. Turn ON the inlet air supply. 2. Turn ON the electrical power. 3. Set the mist header pressure. 4. Depress the “CLEAR” key. These four steps are further discussed below: 1. TURN ON THE INLET AIR SUPPLY.

1.1. Locate the purchasers’ inlet air supply block valve installed in the supply instrument airline between the compressed instrument air source and IVT inlet air connection. The valve should be full opened position.

1.2. Open the door the IVT operator compartment. Locate and open the air block valves to the main oil mist generator. Valves are open when the handles are rotated to the full clock-wise position. Note that when the air supply is opened to the main oil mist generator, the mist outlet valve will automatically operate. The mist outlet valve is pneumatically operated and requires no operator action. The outlet to the main oil mist generator will be opened. The auxiliary oil mist generator outlet will be blocked. For additional information regarding the mist outlet valve operation, see Mist Outlet Switching Valve in the section titled AUXILIARY OIL MIST GENERATOR of this manual.

2. TURN ON THE ELECTRICAL POWER. Before turning on the electrical power, insure that all user provided connections are securely fastened and that covers to all electrical enclosures and junction boxes are tightly secured. Once the system's electrical power is turned on, the solid state control system will power up to monitor current operating conditions by interpreting peripheral input signals. As preset critical alarm conditions are cleared the solid state system controls all of the dependent power systems. The solid state control used in the IVT incorporates built-in safety cutouts for the power circuits (heaters and solenoids). When the power is first turned on, only the air solenoid will be energized to start the oil transfer pump. For a further discussion of how all of the unit alarms are interlocked and displayed see "LOCAL ALARMS, INDICATORS AND READOUT". The LubriMist® Model IVT oil mist generator is equipped with electrical devices that interrupt

the electrical power to either the main oil mist generator or the auxiliary oil mist generator. This commissioning procedure is to start the main oil mist generator. IMPORTANT: The LubriMist® Model IVT oil mist generator is equipped with electrical devices that interrupt the electrical power to either the main oil mist

Page 61: Manual IVT

LubriMist® Model IVT Oil Mist Generator Page 60 of 221

generator or the auxiliary oil mist generator. THIS COMMISSIONING PROCEDURE IS TO START THE MAIN OIL MIST GENERATOR. Note that the power switch arrangements for the NEC and ATEX models are different. 2.1. Locate and energize the electrical power supply at the source. The supply circuit should

be protected with a suitable current limiting device for the service. For additional information regarding voltage and amperage ratings for the IVT Oil Mist Generator see Electrical Power Connection in the section titled INSTALLATION of this manual.

2.2. From the IVT operator panel, locate the power switch. • NEC models are equipped with separate ON – OFF power switches for the main and

auxiliary oil mist generators. The main oil mist generator power switch is located at the top of the panel, directly above the air supply block valve servicing the main oil mist generator.

• ATEX models are equipped with a three-position selector switch ( I-O-II ). The switch is located at the top of the operator panel. The switch center position is the OFF position ( I-O-II ). To energize the main oil mist generator the selector switch should be placed in the full counter clock-wise position. ( I-O-II )

2.3. Now turn on the power to the main oil mist generator. The air solenoid valve will open and start the oil transfer pump. The main oil mist generator reservoir will begin to fill with oil. The rising level in the reservoir can be monitored in the oil level gauge. The low oil level alarm will clear as the level rises above the oil reservoir low-level switch. The oil level will continue to rise until it reaches the pre-set operating control level switch. The air solenoid valve then de-energized once the level rises to the normal operating oil level. A fixed position level switch located in the main oil mist generator reservoir maintains this level.

3. SET THE MIST HEADER PRESSURE. Note that with the electrical power ON and no air passing through the system, the IVT controller indicates alarm conditions for: • Low regulated air pressure. • Low mist pressure. • Low air temperature. • Mist Density Also note that the air / oil heater is de-energized. The heater will not turn on until the low regulated air pressure alarm is cleared. This is to insure that airflow through the air heater is established before the heating element is energized. For a further information regarding all unit alarms and their set-points, see the section titled OPERATING GUIDE of this manual. 3.1. Find the display keypad located on the operator panel and locate the button labeled

"Mist Pressure". Depress the mist pressure button. The control system display now reads "Mist Pressure is 0".

3.2. From the IVT operator panel, locate the air pressure regulator for the main oil mist generator. It is located directly under the air block valve for the main oil mist generator. To increase the mist pressure, the knob on the air filter/pressure regulator is turned in a clockwise direction. To decrease the mist pressure, turn the knob in a counter clockwise direction. Depress the "Mist Pressure" key and monitor the mist pressure as air pressure regulator adjustments are made. Continue to make adjustments with the air pressure regulator until the proper mist pressure is achieved and maintained.

As the regulated air pressure increases and exceeds its low alarm set point the regulated air pressure alarm will clear and the air / oil heater energizes. The air temperature will increase to the normal heater control setting. If the supply air is cooler than the low temperature setting, the low air temperature alarm will clear as the air temperature rises above the low alarm setting.

Once the mist pressure is set, and the mist generator is operating, the mist density reading will increase and clear the low alarm condition. The mist density output reading increases as the oil flows through the heater manifold in air / oil heater and increases in temperature. For

Page 62: Manual IVT

Mist Density Sensor

Operation It is important to recognize that although any given output reading may correspond to a quantitative oil/air ratio, the oil mist sensor does not make a quantitative mass measurement of the amount of oil in the mist. The output signal range of 0-100% represents the ability of a light beam to penetrate the oil mist as it passes between a light source and a light detector. A mist density reading of ZERO indicates that no or very little mist is present; the light has easily reached the detector. As the oil/air ratio increases, the oil mist particles block the light from the detector causing a change in the mist density reading. When light can no longer penetrate through the oil mist particles and reach the light sensor, the monitor reads 100%. The mist density sensor detects and responds to changes in oil/air ratio. However, variations in oil type, grade, viscosity, and regulated air supply pressure to the mist generating head all influence the size of the mist particle created by the generator. This also affects the instrument reading. Other factors that effect particle size distribution and the mist density reading are oil temperature, air temperature and oil level. Before making adjustments, the IVT Oil Mist Generator should be in service and operating normally for a minimum of one hour prior to making sensitivity adjustments or changes in alarm set points. This period allows the oil output to stabilize and the mist sensor internal surfaces to become wetted with oil. Since the mist sensor does not measure the absolute quantity of oil in the mist, it is recommended that a “consumption test” be made if you are striving to achieve a specific oil/air ratio. Lubrication Systems Company recommends that the air oil ratio be adjusted to achieve an oil/air ratio of 0.65 cubic inches of oil / hour / SCFM airflow. For information regarding calibration services, contact Lubrications Systems Company.

Location Of The Mist Density Sensor The mist density is located on top of the bulk oil reservoir. See the product description for the mist density sensor.

Sensitivity Adjustments The mist density monitor is equipped with a user selectable sensitivity adjustment. This feature allows the instrument to adapt to a diverse range of lubricating oils and over a broad range of oil/air ratios. To access the sensitivity adjustment feature, remove the screw-on cover to the electrical enclosure of the sensor unit. Located adjacent to the wire terminals in the detector is a series of electronic dipswitches. Separate switches are provided for 1) low 2) medium and 3) high mist density settings. All units are shipped with the mid sensitivity switch (#2) in the “ON” position. Note the switch #4 interrupts power to the LED light array and should always remain in the ON position.

The signal from the level switch and nine standard / two optional sensors is fed into conditioning circuits of the controller. The conditioning circuit signal is interpreted and scaled by the program to produce gauge values. See "Reading Unit Operating Conditions" on how to check operating conditions. The program performs an ordered series of control set point checks for the maximum and minimum values of each monitored function. If the current value exceeds a maximum setting (high alarm) or is less than a minimum setting (low alarm), the IVT controller recognizes the fault condition and locally identifies the alarm. The Model "IVT" locally identifies and indicates a fault condition in three ways. They are: 1) individual panel indicators, 2) fault message readout on the liquid crystal display and, 3) red and green externally mounted unit status lights.

Page 96: Manual IVT

LubriMist® Model IVT Oil Mist Generator Page 95 of 221

LED Panel Indicator Lights

Red and green enunciator lights are provided to indicate the operational status of all operating variables. When the green LED is illuminated normal operation is indicated. The red LED indicates a fault or system failure. Enunciators are provided for air temperature, oil level (main oil mist generator reservoir), supply air pressure, regulated air pressure (main oil mist generator), oil mist pressure, oil supply pressure and mist density.

Liquid Crystal Display In addition to individual status indicators, the IVT controller utilizes a display to monitor an alarm condition. The display is directly above the local panel alarm indicators. See Item 2, Figure 17. When an operating variable reaches an established gauge alarm setting, the alarm function is identified on the display. Provided there is only one alarm condition the controller will identify the current alarm. When the alarm condition is corrected and normal operation resumes, the display will continue to identify the alarm until the display is cleared. This feature is very important in identifying trouble alarms that may fluctuate between normal and alarm condition.

Red And Green External Status Lights LubriMist® Model IVT is equipped with large, highly visible red and green lights that show normal operation (green) or indicate when an alarm has occurred (red). The unit status lights change from green-on to red-on if any alarm condition is detected. The lights remain red-on / green-off until the CLEAR key is pressed twice and all settings are back to normal. Pressing the CLEAR key the first time clears the alarm message. Pressing the CLEAR key a second time reset s the status lights from red-on / green-off to green-on / red-off.

When changing the light bulbs in the RED and Green status lights, ensure that proper replacement bulbs are used. FAILURE TO DO SO MAY CHANGE THE TEMPERATURE CLASSIFICATION AND RESULT IN A HAZARDOUS CONDITION FOR CERTAIN EXPLOSIVE GAS GROUPS.

MODBUS COMMUNICATION The LubriMist® Model IVT is equipped with a Modbus interface and software to allow for sophisticated automatic data exchange with a host computer. The interface implements the standard Modbus protocol originally developed by Gould Modicon and widely used as a control and monitoring of automated equipment. Additional information on Modbus can be obtained at the Modbus User’s Webster (www.modbus.org). Detailed specifications for the Modbus protocol can be found at www.modicon.com/techpubs/toc7.html. Please note that the information contained in this section is not intended as a Modbus tutorial (refer to the above sources for such information) but explains in detail only those aspects that are particular to the IVT Oil Mist Generator. Also, the particular host computer, host computer software, and transmission medium. Please also note that the interface software used to communicate with the IVT Oil Mist Generator in this document uses Modscan, developed and distributed by Win-TECH. Modscan utilizes the standard Windows Multiple-Document-Interface, (MDI), architecture for displaying Modbus data to the user. Additional information on Modscan can be obtained at (www.win-tech.com). The Modbus interface uses the same data communications port described in Remote Communication And Alarm and much of the installation information is applicable.

Overview The Modbus feature allows the intelligent IVT controller to communicate in a sophisticated and automatic way with a supervisory or monitoring host computer. Modbus is a “master-slave” system. The IVT is designed to act as a “slave” with the host computer acting as the “master”. The host computer is responsible for initiating all communication with the slave. The slave is responsible for responding to the particular and varied requests sent by the master. Modbus is a very versatile communication protocol and the IVT implements a very rich set of Modbus features. All operating conditions of the IVT are available to be read via the Modbus. The usefulness and overall capability of the Modbus system depends mostly on the particular host computer and host computer software and the capabilities thereof. The following sections explain how to install and configure the Modbus feature and how it implements the particular functions of Modbus.

Installation Installing and configuring the Modbus feature must follow the steps outlined below and explained in the sections following.

1. Enable Modbus communication via the dipswitch. 2. Connect the IVT to the host computer through an RS232 RS422/485 converter. 3. Configure the Modbus feature via the IVT control panel. 4. Configure the Modbus software (Modscan) on the host computer.

Serial Data Port – RS-422 The serial communication port can be connected to the serial port of most computers or other serial Data Communication Equipment. An RS-232 RS-422/485 interface converter is required to link to the IVT communication port. The RS-232 RS-422/485 interface converter must be installed in a safe (non-hazardous) location. It is recommended using (B & B Electronics converter, Model 4WSD9R). Setup in RS-422 mode, ECHO OFF, For a 4 wire or 2 wire configurations. Refer to figures 1 and 2 below.

Configuring The IVT Oil Mist Generator A number of settings must be configured into the IVT Oil Mist Generator for Modbus communication to work properly. Most of these settings must also be configured into the software of the host computer, see Configuring The Host Computer. Before the configuration can begin, the following information will be needed:

• The particular Modbus slave address to be used by this IVT unit (a number from 1 to 247) • The mode to be used for communication (RTU or ASCII) • The parity to be used for communication (None, Even, Odd, Mark or Space) • The number of Stop Bits (1 or 2) • The serial speed to be used for communication (300, 1200, 2400, 4800, 9600 or 19,200

bps) It is recommended that this information be documented in a readily accessible location for future reference. Once this information is known, follow these steps to enter it into the IVT Oil Mist Generator:

1. Press the SET key followed by the ENTER key. 2. Unique Unit Numbers should be used if there is more than one IVT connected to the

same host computer. Use the INC and DEC keys to select a unique unit number, and press the ENTER key. If only one IVT is connected to a host computer, simply press the ENTER key again to skip over the Unit Number (it does not affect Modbus communication).

3. The Modbus slave address should now be displayed (001 is the default). If there is more than one IVT connected to the host computer different slave addresses must be used. If it is not as desired, use the INC and DEC keys to set the Modbus slave address from 1 to 247. Press the ENTER key to save the address.

4. The Modbus Transmission Mode should now be displayed (RTU and ASCII). If it is not as desired, use the INC and DEC keys to toggle the mode between RTU and ASCII. Press the ENTER key to save the mode. (RTU is the default and Recommended)

5. The Modbus Parity should now be displayed. If it is not as desired, use the INC and DEC keys to toggle the parity mode between None, Even, Odd, Mark or Space. Press the ENTER key to save the parity mode. (EVEN is the default and Recommended)

6. The number of Stop Bits should now be displayed. . If it is not as desired, use the INC and DEC keys to toggle between 1 and 2. Press the ENTER key to save.

7. The Serial Speed should now be displayed. If it is not as desired, use the INC and DEC keys to select among the available speeds. Press the ENTER key to save the speed. (9600 Baud Rate is the default and Recommended).

Once ENTER key is pressed after setting the Serial Speed the display screen sequence continues to set other system features that do no effect Modebus communication. Press the CLEAR key to return to Run-Time screen and normal operation. The IVT Oil Mist Generator software is now ready to begin Modbus communication.

Configuring The Host Computer The host computer must be configured according to the specific instructions outlined below for the Modscan screen to send and receive data to the IVT Oil Mist Generator. (See Configuring The IVT Oil Mist Generator): Please note if another host computer Modbus software is to be used all settings must be the same in the IVT Oil Mist Generator as they are in the host computer. Failure to enter the correct parameters will cause a communications error.

The Modscan screen can be customized in many different configurations, but for the purpose of this document, only 2 will be covered.

1. Breakdown of each Function Code and it’s HEX Addresses. 2. Viewing the IVT’s values in real time.

Before number 1 can be analyzed, below is a brief description on the Function Codes and the HEX Addresses.

Function Codes There are the four Function Codes that are utilized by the IVT controller program. In that, there are 52 different parameters in the IVT program that can be read by Modscan. Each of the 52 parameters is broken down into their specific Function Codes (01---04). Function Code description Explanation 01 Coil Status has 6 Digital outputs 02 Input Status has 9 Digital inputs 03 Holding Register has 24 Setpoints 04 Input register has 13 Analog inputs To view a particular parameter or a range of parameters select the function code under the (MODBUS Point Type) in the Modscan screen. In the Address (HEX) box select the start address; in the length box select the amount of parameters to be polled. See figure 3

Page 118: Manual IVT

LubriMist® Model IVT Oil Mist Generator Page 117 of 221

Note; for the purpose of this procedure assume that 0001 is used in the Address (HEX) box and 1 in the length box. Hex Address Base 16 (Hexadecimal) digits 0 thru 9 and A thru F. A represents 10, B represents 11, C-12, D-13, E-14 and F-15. Each number occupies a place value. When F is reached, the value goes to 0 and 1 is added to the next place value, so 10 would be 16 and so on. The original designers of Modbus used 1 as the starting value of Coils, Inputs and Registers, reserving 0 for another use. That is why in the procedure that follows, Address (HEX) 0001in the Modscan screen, will represent 00 in the message frame, 0002 represents 01, 0003- 02, 0004-03 and so on. Refer to figure 4.

(also known as the Slave Address). 2) Modbus point type or function code ---- selecting 01 (Coil Status) from the Modscan screen will determine which values or parameters will be viewed. This is where the function code shows up in the message frame. 3) Data sent---will consist of 2 sets of data ([00] [00]), ([00] [01]), the first two sets of numbers [00] [00] are the address (hex), meaning (Mist tank level, Air heater, Air pre-heater, etc). Remember: In the Modscan screen Address (hex) 0001 means 00 in the message frame, 0002—01, etc. Only one output status value can be polled at anyone time using this format, to view a value, type in the address in the Modscan screen address (hex) box. See Coil Status addresses below. The second set of numbers [00] [01] are the (length). In Coil Status, only one value can be polled at a time, it is recommended to leave the length at 1 when working in Coil Status for this format. 4) Cyclical Redundancy Check--- CRC [fd] [ca], is a number assigned by the computer and cannot be changed by the user. Function code 01—in Modscan screen the address (hex) and the length cannot exceed 11 Or an error will occur in the receiving information from the IVT in the form of ([01] [81] [00] [40] [50]), the [81] being the error code. Coil Status Addresses;There are only 6 addresses (HEX) available in coil status.

The first two sets of numbers are the same as the previous. 1) The device ID (01) 2) The Function code (01). 3) Data Received---Has 2 sets of numbers a [01] and [02]. The [01] represents the number of bites of value status being received (black field), meaning for every single digit added to the length in the Modscan screen the value status received (black field) will increase by two, except in function codes 01 (Coil Status) and 02 (Input Status) in this format. Only one value can be polled at a time, so it is recommended to leave the length at 1 when working in Coil Status 01 in this format. The [02], is the value status of the address being polled. The status of the address being polled doesn’t necessarily mean it is going to come back in the form of a 1 or 0, on or off. It can also come back in the form of Odd # or Even #, but break down those numbers in binary form and they will be 1 or 0. From the IVT, here’s how it breaks down. Even # or O = N.O. normally open --- OFF Odd # or 1 = N.C. normally closed --- ON 4) Cyclical Redundancy Check--- CRC, is a number assigned by the computer and cannot be changed by the user.

bites of value status being received (black field), meaning for every single digit added to the length in the Modscan screen the value status received (black field) will increase by two, except in function codes 01 (Coil Status) and 02 (Input Status) in this format. Only one value can be polled at a time, so it is recommended to leave the length at 1 when working in Input Status 02 in this format. The [80] is the value status of the address being polled. The status of the address being polled doesn’t necessarily mean it is going to come back in the form of a 1 or 0, on or off. It can also come back in the form of Odd # or Even #, but break down those numbers in binary form and they will be 1 or 0. From the IVT, here’s how it breaks down The status of components in the Input Status is the opposite of the Coil Status. Even # or 0 = N. C. normally closed or ON Odd # or 1 = N. O. normally open or OFF

To poll a single value, type in the address in the Modscan screen address (hex) box. See Holding Register addresses below. The second set of numbers [00], [01] are the (length). In Function Code (03) the length can have up to 24 polling places, which will give a hex value of [18], in the sent message frame. Note: In order to poll all 24 Holding Register Address values, the length has to be set at 24 and the Address (HEX) has to be set a 1. The Holding Register Addresses can only be polled in consecutive order. Meaning either from the beginning of the string, anywhere in the middle or the end of the string can be polled. Trying to poll random Holding Register Addresses cannot be done. Example; (02 air temp., 07 supply air press., 09 reg. air press.), cannot be polled as a string. 2) Cyclical Redundancy Check--- CRC, is a number assigned by the computer and cannot be changed by the user. Function code 03—in Modscan screen the combined address HEX and the length cannot exceed 25 Or an error will occur in the receiving information in the form of ([01] [83] [00] [41] [30]), the [83] being the error code.

Message frame being received Holding Register, Function code 03, Refers to the setpoints from the IVT ([01] [03] [02] [07] [cf] [fa] [20]). 1) Device I.D. in Modscan screen has to be the same as the IVT location

2) In the Modscan screen Modbus point type & Function code are the same thing

3) Data Received, consisting of length and the status being polled

4) Cyclical Redundancy Checking or CRC

[01] [03] ([02]) ([07] [cf]) [fa] [20] The first two sets of numbers are going to be the same as the previous. 1) Is the device ID 01. 2) The Function code 03. 3) Data Received---Has 3 sets of numbers a [02] and a [07] [cf]. The first set of numbers [02] represent the number of bites of the value status being received (black field), meaning for every single digit added to the length in the Modscan screen two bites of data will be received, so if the length is 1 in the Modscan screen, a [02] is sent back in the message frame being received (black field). If the length in the Modscan screen were 2 the data sent back would be [04], if it were 3 then it would be [06] and so on. The second set of numbers is the value being polled in HEX, Example [07] [cf] in hex is 1999 in decimal, and this is the number identifier for that particular IVT. If the length were 2, in the Modscan screen, from the statement previous, the data received would be [07] [cf] [00] [78]. It would send back the first 2 sets of values in the Holding Registry from Address (HEX) 0001 which are (LubriMist Unit Number meaning [07] [cf] in HEX or 1999 in decimal, and Air Temp. Control Setpoint meaning [00] [78] in HEX or 120 in decimal. So if the length were set at 24, then all the values would be received from the IVT controller, in the black field. Refer to figure 5.

Input Register Function Code 04, Refers to the analog inputs For a description of the input registers refer to (Input Register Addresses) below. In this example, Address (HEX) 0002 and a length of 1 are used. Note; The Air Pre-heater Enable temp. Address (HEX) 0001 is not always used in an IVT. So if it were used in the Input Register function code 04 below for this example an erroneous value of 65078 for the (Air Pre-heater Enable temp.), would be given. By using Address (HEX) 0002 Bulk Oil Reservoir Level, a reasonable value can be ascertained. Message frame being sent, [01] [04] [00] [01] [00] [01] [60] [0a] 1) Device I.D. in Modscan screen has to be the same as the IVT location

To poll a single value, type in the address in the Modscan screen Address (HEX) box. See Input Register addresses below. The second set of numbers [00], [01] are the (length). In the Function Code 04 the length can be up to 13, which will give a [0d] in the sent massage frame. (0d hex = 13 in decimal) Note: The length has to be a 1 in order to poll only 1 address. 4) Cyclical Redundancy Check--- CRC, is a number assigned by the computer and cannot be changed by the user. Function code 04—in Modscan screen the address HEX and the length cannot exceed 14. Or an error will occur in the message frame being received in the form of ([01] [84] [00] [43] [00]), the [84] being the error code.

The first set of numbers [02] represent the number of bites of the value status being received (black field), meaning the length in the Modscan screen is 1 so a [02] is received in the message frame (black field). If the length in the Modscan screen were 2 the data received would be [04], if it were 3 then it would be [06] and so on. The second set of numbers is the value being polled in HEX, Example [00] [44] = 68 in decimal, this is value that’s received for the Bulk Oil Reservoir Level. (This would be in gallons) If the length were 2 in the Modscan screen and the starting HEX Address were 02, then from the previous statement. The data received would be [00] [44] [00] [46]. The first two bites of data [00] [44] bulk Oil Reservoir Level would have a decimal value of 68 in gallons and the second set of data bites [00] [46] would be the Ambient Temp. with a decimal value of 70 (this would be degrees in Fahrenheit). 4) Cyclical Redundancy Check--- CRC, is a number assigned by the computer and cannot be changed by the user.

General Information All Modbus transmitted values consist of one or more 16-bit binary “words”. These are used in various ways to represent the particular item or value as determined by the message context. The format used for Coil Status or Input Status is explained first followed by that for Holding Registers or Input Registers. Coil Status or Input Status is transmitted in what is sometimes called a “packed-bit” format. This refers to the fact that the individual status values are “packed” into the individual bits of a larger 16-bit data word. Specifically, the individual bits are arranged in increasing numeric order, according to their data address, and starting at bit number zero.

High byte of 16-bit value Low byte of 16-bit value 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 S15 S14 S13 S12 S11 S10 S9 S8 S7 S6 S5 S4 S3 S2 S1 S0 S0 = Status bit transmitted with lowest address number … S15 = Status bit transmitted with highest address number Note that if a particular transmission request involves less than 16 individual status addresses, then the upper bits will be unused. The Modbus specification allows for many more than 16 status bits to be transmitted at one time using multiple 16-bit words but the IVT Oil Mist Generator has no need to ever transmit more than ten (10) at one time. Holding Registers or Input Registers are transmitted as 16-bit words with one analog numeric value per word. The format used is what is referred to as “twos-complement” integer form. Each 16-bit value is treated as a 15-bit integer with a 1-bit sign. This allows for the transmission of negative numbers for those registers that may need to represent values below zero. Fifteen integer bits plus sign allow for numeric values in the range –32768 to +32767.

These values are transmitted as “twos-complement” integer numbers. This is a standard method used in computers to represent signed integers. The following table shows how common values would be represented in twos-complement form.

16-bit Twos-Complement Representation Signed Decimal

Number Binary Decimal Hexadecimal -32,768 1000000000000000 32768 8000 -32,767 1000000000000001 32769 8001

Although this representation may appear strange at first, it is useful and numerically correct because simple addition and subtraction yield correct results and it is the most commonly used format for that reason. The actual values transmitted for a given analog input or set point are an exact replica of what is seen on the control panel in the selected units (English or metric) with an implied decimal point where applicable. For example, those values with two digit positions to the right of the decimal point would be transmitted as a numeric value of one hundred times (100x) the reading seen on the control panel. So the value 123.45 would be transmitted as 12,345 and the host software will need to scale accordingly. Note that this only affects those data values representing metric units of Bars such as supply air pressure, regulated air pressure and supply oil pressure and their related high and low alarm set points. It does not apply to any values when using English units since all are displayed with no digits to the right of the decimal point.

Bulk Oil Supply Reservoir

General Description and Use: The IVT Oil Mist Generator console includes an integral bulk oil supply reservoir. As oil is consumed during the normal process of providing oil mist lubrication to the serviced equipment the volume of oil in the bulk oil reservoir will decrease. The decrease in volume is monitored in two ways. An oil level sight glass is located behind the front cabinet door. The operating level can easily be check and monitored from this location. Second, the bulk oil reservoir is equipped with an oil level transmitter that is interfaced with the IVT controller. Additional information on read outs and remote monitoring can be found elsewhere in this manual. .

Commission The Auxiliary Oil Mist Generator Before oil can be added to the bulk oil supply reservoir, the main oil mist-generating unit must be shut down and the auxiliary unit must be commissioned. This being because the air space above the oil levels in the bulk oil reservoir and the main oil mist generator is common. During normal operation, mist flows from the main oil mist generator into the bulk oil reservoir before exiting the IVT Oil Mist Console. This feature provides an oil mist purge on the bulk oil reservoir and keeping it clean. Instructions for changing from the main to the auxiliary oil mist generator can be found in the section of titled AUXILIARY OIL MIST GENERATOR.

Adding Oil To The Bulk Oil Reservoir Once the main oil mist generator has been removed from service and the auxiliary oil mist generator has been started oil can be added to the bulk oil reservoir. Oil may be pumped directly from drums or other bulk supply source through a supply hose. A clean 10-micron (nominal) oil filter should be used while filling the bulk supply reservoir. To fill the reservoir, follow these steps.

a) Open the operator compartment door. Verify that the Drain valves for the bulk oil reservoir, the main oil mist generator reservoir and the auxiliary oil mist generator are in the closed position. Valves are closed when their handles are rotated to the full clock-wise position. Valves should have drain plugs installed and secure.

b) Locate the bulk oil reservoir fill cap. The cap is located to the right of the spin-on oil filter. Loosen and unscrew the oil fill cap and set aside. Note that the cap is connected to the reservoir with a chain to discourage misplacing.

c) Check the end of the oil fill hose for contamination. Clean away any dirt and grit that may be in or on the hose end nozzle. Insert the hose into the fill connection and fill the reservoir. Initial fill should be a minimum of 55-gallon drum.

While filling the bulk oil supply reservoir, monitor the oil level gauge. DO NOT OVER FILL.

The total reservoir capacity is approximately 75 gallons maximum. Overfilling will result in oil overflowing out of the fill connection and onto the ground.

WARNING

d) Once filling is complete, remove the oil supply hose and reinstall the oil fill cap. The cap

is threaded and seals with an o-ring. Care should be taken to ensure proper thread alignment and engagement. The cap needs only to be firmly tightened by hand. The oil hose should be wiped clean and stored in a manor to avoid contamination. It will be needed in the future for refilling the oil reservoir.

Take care when installing the oil fill cap. Ensure that threads are clean prior to installing. Take care to ensure that threads are started straight and that no cross threading occurs when installing. Do not use pliers or any other hand tool to grip and tighten the oil fill cap. Tighten hand tight. DO NOT OVER TIGHTEN.

Commission The Main Oil Mist Generator Once filling of the bulk oil reservoir is complete, remove the auxiliary oil mist generator from service and commission the main oil mist generator. Instructions for changing from the auxiliary to the main oil mist generator can be found in the section of titled AUXILIARY OIL MIST GENERATOR.

Auxiliary Oil Mist Generator

General Description and Use: The IVT Oil Mist Generator console includes an integral auxiliary oil mist generator. The auxiliary unit is provided for use when maintenance or repair operations are being performed on the main oil mist generator

IMPORTANT: The auxiliary oil mist generator is intended for intermittent use only. When operated for purposes other than to perform routine maintenance or repair of the main oil mist generator, it should be checked at the beginning of every shift for proper operation.

The auxiliary oil mist generator is operator accessible from the operator panel. The controls for the auxiliary oil mist generator are located on the right side of the operator panel. A separate electrical power switch is provided in the NEC configuration of the IVT Oil Mist Generator. In the ATEX version the three-position selector switch switches power from the main to the auxiliary oil mist generator. Reference the descriptions in the Operator Panel section of the PRODUCT DESCRIPTION for additional information. A low air pressure switch is located in the mechanical compartment. Mist pressure and reservoir oil level gauges are provided to locally monitor the mist pressure and reservoir oil level once the unit has been placed into operation. A plugged reservoir drain valve is provided for draining and cleaning the reservoir as needed. Just as the main oil mist generator, the auxiliary oil mist generator includes an integral air oil heater. The heater controls are accessible from the operator panel. Also located on the operator panel are two manually operated toggle valves for filling the auxiliary oil reservoir from the bulk oil supply tank.

The Right side mechanical compartment encloses the air oil heater, the mist-generating head, the low air pressure switch and the air temperature sensors. The heater element is interlocked with the low air pressure switch and is inoperable if the regulated air pressure is less set less than 10 PSIG. This ensures that airflow is established before power is applied to the element. A regulated air pressure gauge is mounted on the mist generator head to indicate the regulated air pressure being supplied to the mist generator. A manual reservoir fill port and a non-adjustable pressure pop off valve are also provided. The oil mist discharge is automatically switched between the main and auxiliary oil mist generator as the air supplies are adjusted.

Auxiliary Oil Mist Generator Start-Up Using the auxiliary oil mist generator is made possible by following only a few simple steps. 1) Check the reservoir oil level and fill if necessary. The reservoir is normally filled from the bulk

oil reservoir using the air operated oil transfer pump. Filling the reservoir is accomplished by manually opening and holding BOTH toggle valves in the open position. The toggle valves have lever type handles with spring return. The valves will revert to the closed position if they are not manually held in the open position. This is to prevent inadvertent overfilling

IMPORTANT: The air supply valve to the auxiliary oil mist generator should be opened prior to filling the reservoir. This will operate the mist outlet valve and allow the air volume in the reservoir to vent through the mist outlet as the oil fills the reservoir space. Also ensure that the reservoir drain valve is closed and the plug secure.

Pulling UP or pressing DOWN on the valve lever opens the valves. The toggle valve located toward the left supplies air pressure to the oil transfer pump. The toggle valve located on the right opens the pump discharge to the auxiliary oil mist generator reservoir. Open and hold the air and oil toggle valves in the OPEN position. When the AIR toggle valve is opened, the transfer pump will start to operate and the oil passes through the oil filter. If the OIL toggle valve is not held in the open position, the oil pressure opens the check valve located on the main oil mist generator reservoir and begins to fill the main oil mist generator reservoir. When the OIL toggle valve is held in the open position, the check valve spring pressure forces the oil to flow through the Oil toggle valve to fill the auxiliary oil mist generator reservoir. While filling, monitor the oil level in the oil level gauge. The reservoir should be filled to approximately 2/3 full.

CAUTION: Do not overfill the auxiliary oil mist generator reservoir. An air space must be maintained above the oil level for mist generation and flow between the mist generator and the mist outlet. If your system includes auto drain legs allowance must be made to collect the return oil volume.

The oil transfer pump speed should be limited to approximately 200 cycles per minute. Adjusting the air pressure regulator to the oil transfer pump controls the pump speed. If the pump fails to operate, ensure that the air supply block valve is in the open position. Pump speed increases when the air pressure regulator knob is turned clock-wise. The pump speed decreases when the regulator knob is adjusted in the counter-clock wise direction. When the auxiliary oil mist generator is initially filled from a dry reservoir, the fill time to 2/3 full is approximately 10 minutes. The pump discharge rate at 200 cycles per minute is approximately 0.71 GPM (2.9 liters per minute).

IMPORTANT: The main oil mist generator may be allowed to continue to operate while the auxiliary oil mist generator is allowed to fill. If the main unit is allowed to operate, place the air pressure regulator for the auxiliary oil mist generator in the closed or full counter-clock wise position prior to opening the supply air valve. Failure to do so may result in a high mist pressure condition.

2) Turn OFF the electrical power to the main oil mist generator

a) The electrical power switch is located in the top of the operator panel. Separate power switches are provided for the main and auxiliary oil mist generators in NEC configured units. The main oil mist generator switch is located on the left side. Move the switch to the OFF position.

b) For ATEX configured units, power is supplied through a three-position selector switch. To turn power OFF to the main oil mist generator move the selector switch to the center position.( I O II )

3) Turn OFF the air supply to the main oil mist generator. a) Adjust the air pressure regulator to the closed position. Turning the adjustment knob on

the air pressure regulator in the full counter clockwise position places it in the closed position. The mist pressure will bleed to zero.

b) Close the air supply block valve to the main oil mist generator. If the air supply to the auxiliary unit is ON, the mist outlet valve will operate to close the mist outlet to the main oil mist generator.

4) Turn ON the air supply to the auxiliary oil mist generator and adjust the mist pressure. The air supply block valve must be in the open position. Turning the air pressure regulator adjustment knob makes adjustments to the mist pressure. Turning the knob in the clock-wise direction increases mist pressure. Turning it in the counter-clock wise direction decreases the mist pressure. Monitor the mist pressure gauge as adjustments are made. Normal mist pressure setting is 20 inches of water / 50 m BAR.

5) Turn ON the electrical power to the auxiliary oil mist generator a) The electrical power switch is located in the top of the operator panel. Separate power

switches are provided for the main and auxiliary oil mist generators in NEC configured units. The auxiliary oil mist generator switch is located on the right side. Move the switch to the ON position.

b) For ATEX configured units, power is supplied through a three-position selector switch. To turn power ON to the auxiliary unit move the selector switch to the right position.( I O II )

Once the auxiliary oil mist generator has been commissioned, check the air oil heater for operation and proper set point.

Operation Once the auxiliary oil mist generator has been placed in operation, maintenance and repair to the main oil mist generator can be performed. The main oil mist generator should be placed back in service as soon as possible. If the auxiliary oil mist generator remains in operation for an extended time period, it should be monitored to ensure that the oil level, air temperature and mist pressure is maintained. As oil is consumed, refilling the reservoir can be done with the unit in full operation by holding both toggle valves in the open position while monitoring the rising level in the oil level sight glass. Reference step no. 1 above.

Air / Oil Heater Operation And Temperature Adjustment. The auxiliary oil mist generator is equipped with an integral air oil heater. This is the same as the heater assembly installed on the main oil mist generator reservoir. A separate solid state controller controls the heater element for the auxiliary oil mist generator. See the section titled Auxiliary Oil Mist Generator in the PRODUCT DESCRIPTION section for further description of the heater and its controls.

IMPORTANT: The heater element controls are interlocked with the low air pressure switch. The heater remains inoperable until the regulated air pressure increases above 10 PSI. This is to ensure that airflow over the element has been established before electrical power is applied. To check the regulated air pressure, open the right side mechanical compartment door to view the regulated air pressure gauge. The gauge is mounted on the right side of the mist generating head body.

Readout and parameter management is performed through the LED display and membrane panel key switches. When the power is shut off, or in case of power failure, control parameters are saved in non-volatile memory. The components are specified for operation from –40 to +180° F / -40 to +82° C) The controller is a dual thermocouple unit with solid state relay voltage drive outputs for control and alarm functions. The control uses type K thermocouples. The temperature control thermocouple provides the signal for switching the electrical power via a solid state relay. A second type K thermocouple is used for a high temperature alarm and heater cutout.

Controller Operation The control begins operation as soon as power is applied and shows the process temperature display. The control output (SSR1) will be fully ON if the temperature of the control thermocouple (#1) is below the programmed bandwidth, fully OFF above the programmed bandwidth and proportional within the bandwidth. If the temperature of the cutout thermocouple (#2) is below the programmed cutoff Set-point, the cutout output (SSR2) will be ON. If the temperature of the #2 thermocouple is above the programmed cutoff Set-point, SSR2 will be OFF. If the temperature of thermocouple #2 falls below the programmed Low Alarm Set-point, the “Ξ” LED on the front panel will be illuminated. If either thermocouple sensor becomes open circuited, the display will read “EEEE” and both SSR outputs will be held in OFF until the problem is corrected. If the regulated air pressure switch contacts are OPEN (low pressure), the HEAT and CUTOFF outputs will be held OFF. When the regulated air pressure exceeds 10 PSIG, these outputs function normally.

Programming And Changing Set-points

The default control set point for the auxiliary air / oil heater is 120° F / 49° C. The high temperature cutout is preset at 140° F / 60° C. The low temperature alarm setting is 100° F / 38° C. All temperature settings can be viewed or changed by following the following procedure. Push the SET key once. The display will show the current process control setpoint and the rightmost digit will display “1”. The UP and DOWN arrow keys will adjust the process control setpoint between the limits of 100F and 140F (or equivalent degrees C, if F/C parameter is set to C). Pushing SET again will advance to the next parameter, but if no key is pushed for 10 seconds, the control will automatically return to the temperature display and control screen. Push the SET key again. The display will show the current BANDWIDTH and the rightmost digit will display “b”. The UP and DOWN keys will adjust the bandwidth between the limits of 0.5F and 20.0F (or equivalent degrees C, if F/C parameter is set to C). Bandwidth is the effective gain of the controller. A small bandwidth will approach on-off type control while a large bandwidth will

accommodate thermal systems with more time lag. Pushing SET again will advance to the next parameter, but if no key is pushed for 10 seconds, the control will automatically return to the temperature display and control screen. Push the SET key again. The display will show the current temperature cutoff setpoint and the rightmost digit will display “2”. The UP and DOWN arrow keys will adjust the temperature cutoff setpoint between the limits of 100F and 190F (or equivalent degrees C, if F/C parameter is set to C). Pushing SET again will advance to the next parameter, but if no key is pushed for 10 seconds, the control will automatically return to the temperature display and control screen. Push the SET key again. The display will show the current alarm setpoint and the rightmost digit will display “3”. The UP and DOWN arrow keys will adjust the alarm setpoint between the limits of 60F and 100F (or equivalent degrees C if F/C Jumper is ON). Pushing SET again will advance to the next parameter, but if no key is pushed for 10 seconds, the control will automatically return to the temperature display and control screen. Push the SET key again. The display will show the current temperature display units and the rightmost digit will display “U”. The UP and DOWN arrow keys will toggle the display units between FAH and CEL. Pushing SET again will advance to the temperature display and control screen, but if no key is pushed for 10 seconds, the control will automatically return to this screen anyway.

. The air / oil heater will now resume control at the new control and alarm settings.

Switching From The Auxiliary Oil Mist Generator To The Main Oil Mist Generator. Once the main oil mist generator has been serviced or repaired, it should be put back in service. 1) Turn OFF the electrical power to the auxiliary oil mist generator The electrical power switch is

located in the top of the operator panel a) Separate power switches are provided for the main and auxiliary oil mist generators in

NEC configured units. The auxiliary oil mist generator switch is located on the right side. Move the switch to the OFF position.

2) Turn OFF the air supply to the auxiliary oil mist generator. a) Adjust the air pressure regulator to the closed position. Turning the adjustment knob on

the air pressure regulator in the full counter clockwise position places it in the closed position. The mist pressure will bleed to zero.

b) Close the air supply block valve to the auxiliary oil mist generator 3) Commission the main oil mist generator as described in the section titled COMMISSIONING

in this manual.

Mist Outlet Switching Valve The Model IVT Oil Mist Generator console is equipped with a pneumatically operated switching valve that automatically connects the mist outlet of either the main or auxiliary oil mist generator to the mist outlet pipe. When the air pressure is being supplied to the main oil mist generator the mist outlet is open to the main oil mist generator and closed to the auxiliary unit. When the auxiliary oil mist generator is operating the mist outlet valve automatically opens to the discharge of the auxiliary oil mist generator and blocks the outlet to the main oil mist generator. If air is being supplied to both the main and the auxiliary units, both outlet connections are open and both units discharge mist into the distribution header system.

IMPORTANT: The main and auxiliary oil mist generators should not be operated in parallel. The fail open design is intended to safe guard against unintentional improper switching between the main and auxiliary oil mist generator. Failure to properly follow instructions may result in a high mist pressure condition.

The valve uses the supply and regulated air pressure being supplied to the main and auxiliary mist generators to operate. The following operating sequence assumes the air block valves are closed and the air pressure regulator adjustments are at zero for both oil mist generators. 1) When the main oil mist generator air block valve is opened, the air pressure signal down

stream of the valve increases to the supply pressure setting (150 PSI maximum). Air pressure is applied to the bottom of the main air cylinder, moving the valve poppet UP, thus opening the mist outlet to the main oil mist generator. As the regulated air pressure setting increases, air pressure is applied to the top of the auxiliary air cylinder. The air cylinder moves the valve poppet to the auxiliary unit discharge DOWN and presses it against the seat.

Adjusting Air / Oil Ratio LubriMist® Vortex oil mist generation technology allows for maximum control and adjustment of oil mist properties. There are four basic controls for adjusting the oil output of the mist generator.

1. The AIR PRESSURE REGULATOR is used to adjust the volume of air flowing into the Vortex chamber, which in turn controls oil mist volume. The air pressure regulators are located on the operator panel. The volume of oil mist is proportioned to each bearing or application point by the reclassifier. With the air bypass valve (described below) closed, the air pressure regulator setting must be high enough for oil mist production. Regulated air pressure should be adjusted to maintain proper mist pressure. Since changes in regulated air pressure affect the volume of oil mist produced, it also affects oil consumption. Separate air pressure regulators are provided for the main and auxiliary oil mist generators.

2.

Lubrimist

The AIR / OIL HEATER controls the temperature of the oil as it is being converted from a liquid into oil mist particles. Because oil viscosity has a definite influence on oil mist generation, increasing and decreasing the oil temperature effects a change in the mist density as the oil temperature is varied. Generally, when the air / oil heater is operating, the oil temperature runs approximately 10-12° F (5-7°C) cooler than the air temperature. An increase in temperature will increase oil output. Decreasing the temperature will cause the oil output to also decrease. See Programming User Established Alarm And Control Set Points in the OPERATING GUIDE section of this manual for instruction on changing set points for the main oil mist generator. Adjusting the heater controls for the auxiliary oil mist generator is covered in the AUXILIARY OIL MIST GENERATOR section of this manual.

Use Auxiliary Oil Mist Generator Control Panel To Manage Auxiliary Air / Oil Heater Setpoint

IMPORTANT: The oil/air ratio or mist density is also dependent on the characteristics of the oil, oil temperature and supply air temperature. Density decreases with lower temperatures and higher oil viscosity.

Page 146: Manual IVT

LubriMist® Model IVT Oil Mist Generator Page 145 of 221

3. The OIL FLOW VALVE controls oil mist density (oil/air ratio). Its normal position is fully

closed. By turning it counter-clockwise (opening the bypass) the mist density can be reduced when leaner density oil mist is desired. It should not be opened more than three turns. Adjustments to the oil flow valve do not affect oil mist pressure. The oil flow valve is located on the front of the mist generating head body. Separate mist generating heads are provided for the main and the auxiliary oil mist generators.

4. The AIR BY-PASS VALVE controls mist pressure without effecting oil output. Its normal position is fully closed, but by turning it counter clockwise more air will be added to the oil mist leaving the generator. This essentially dilutes the air / oil ratio by adding more air. Without reducing the regulated air pressure setting, adjusting the air by-pass valve increases mist pressure and reduces the oil/air ratio. Velocity of mist through the distribution lines and reclassifiers will also increase when this valve is opened. The air by-pass valve is located on the right of the mist generating head body. Separate mist generating heads are provided for the main and the auxiliary oil mist generators

Changing The Mist Generating Capacity A qualified person should make replacement of parts. The IVT Oil Mist Generator is designed to provide oil mist lubrication for systems over a wide range of oil mist flow requirements. The IVT package can easily be set up to service oil mist systems with mist capacity requirements from 1.2 to 30 SCFM. The mist generators of the same capacity are always installed in the main and auxiliary mist units. When system flow requirements change due to the addition or deletion of mist application points, the mist generating capacity of the IVT Oil Mist Generator must be verified. If necessary a new mist generator insert kit can be easily installed to keep up with the new mist generating requirements. The IVT Oil Mist Console is shipped as one of four different mist-generating capacities. The four different capacities are listed in the table below. Reference Tag Detail For NEC Model IVT and Tag Detail For ATEX Model IVT in the UNIT IDENTIFICATION AND LABELING section of this manual for additional information.

ROUTINE MAINTENANCE Whenever equipment is provided with pure (dry sump) oil mist lubrication, it is important to insure constant, uninterrupted operation of the oil mist lubrication systems. If a malfunction occurs, early detection and corrections are important. The daily operation of the oil mist system for the process operator has been reduced to checks of the IVT Oil Mist Generator and lubricated equipment and to emergency procedures in the event of a major malfunction. Except for emergencies, routine adjustment of the oil mist generator is not required. Each oil mist system, once installed and balanced, supplies a constant amount of oil mist to a number of lubrication points. Any change in the oil mist pressure or in the regulated air pressure (load pressure) from the initial set points is an indication that some component has failed. Minor adjustments that might offset the failure symptoms may lead to more serious problems before detection and corrections can be made. Keeping system adjustments to a minimum is intended to make the oil mist systems more reliable and to insure proper operation. It is not meant to discourage the natural troubleshooting initiative of the process technician. Operators should be familiar with "Model IVT Operating Guide", knowing how to read gauge values and alarm settings before attempting these procedures.

1) DAILY OIL MIST GENERATOR CHECKS

a) Check mist header pressure setting @ 20 inches H2O / 50 m BAR

b) Check low mist pressure alarm setting (Factory setting is 10 inches H2O / 25 m BAR

c) Check high mist pressure alarm setting (Factory setting is 30 inches H2O / 75 m BAR

Low pressure may indicate a leak in system, reclassifiers removed from the system or broken lines.

High pressure may indicate plugged mist fittings of an open bypass valve.

Surging pressure may indicate an oil pocket in the distribution header or inlet air pressure not constant.

d) Check regulated air pressure and the supply air pressure. This regulated air pressure is preset and should not be adjusted to regulate mist header pressure.

Generator will not operate properly below 10 PSIG - 0.7 BAR regulated air pressure.

Supply air pressure should be approximately 20 PSIG – 1.5 BAR) above the regulated air pressure.

e) Check for proper air temperature setting (Factory setting is 120° F - 49° C).

f) Check oil level in the main generator reservoir.

g) Check general unit condition for leaks, broken gauges, etc. and repair as needed.

2) WEEKLY CHECKS

a) Check all control and alarm set points.

b) Clean inside of generator console and correct any leaks.

3) MAINTENANCE CHECKS

The following maintenance procedures should be performed at least on a semi-annual basis to help insure proper system operation. If your “IVT” is installed in an extremely dusty or humid environment or if you are concerned about the quality of your compressed air supply, the maintenance schedule should be accelerated. Consult with the nearest LSC office/service center for further discussion and recommendations.

a) Change oil filter element (P/N 77-500-487).

b) Inspect and clean the oil suction screen (P/N LS0205120).

c) Replace air filter element (P/N 77780352).

d) Inspect and thoroughly clean the interior of the oil mist generator reservoirs.

Page 152: Manual IVT

LubriMist® Model IVT Oil Mist Generator Page 151 of 221

e) Check and verify operation of the high and low set points of all alarms.

f) Check the operation of the remote alarm circuit if one has been installed.

g) Make an overall assessment of the “IVT” and mist distribution system and correct obvious deficiencies and problems.

SOLUTION

LOW MIST DENSITY Oil Mist Density is below Low Alarm Setting – Oil Mist quality has been compromised. (10%)

1. Turn mist inspection valve. Visually inspect oil mist quality. 2. Check oil level in mist tank. Confirm Oil Supply Level alarm on front of keypad is

not in active. Verify that the operating oil level is in the normal operating range. Loss of oil results in loss of oil mist production.

3. Press Air Temp key. Confirm air temperature is at control set point (120°F - 49°C). If customer assigned values replace factory values: To check control setting press key combination Set, Air Temp. When finished, press the Clear key to return to normal operating mode. Note: Decline in Air Temperature will cause the oil viscosity to increase resulting in a decrease in mist production.

4. Confirm mist head oil flow valve has not been adjusted further than 3 turns. See mist head adjustment screw locations below. Closing the oil flow valve increases the oil mist output. Note: Excessive adjustment to this valve may compromise the oil mist heads ability to produce quality oil mist.

5. Confirm mist head air bypass valve is not over adjusted. Note: Excessive adjustment to this valve may over dilute the oil mist with clean air. Closing the air by-pass valve decreases dilution. Note that adjustments using the air bypass valve varies mist pressure.

6. Check the oil suction screen for obstruction. • Switch to Auxiliary Unit. See instructions located on interior of IVT cabinet

door. • Open the left IVT cabinet door. Locate oil suction screen holder on the side

of the mist head. Remove the oil suction screen and clean thoroughly, reinstall when through.

Note whether customer assigned values have been programmed to the replace the factory values. Press the key combination Set, Mist Pres. to read the low alarm setting. Press the Clear key to return to normal operating mode.

2. If the mist pressure is near the Low Alarm Setting (10in H2O – 25mBar) check the oil mist header systems for broken mist lines or pipes and IVT oil mist generator for leaks.

3. Verify that the regulated air pressure has not been changed from the original setting established at commissioning. When adjustments are made, the EVENT LOG records the event. See the section titled Event Log under LOCAL ALARMS, INDICATORS AND READOUT in the Installation and Operating Manual for instruction on how to access the event log. If it is determined that the regulated air pressure has been changed, and that the Low Mist Pressure alarm is due the change in regulated air pressure correct the setting. Adjust the air regulator to achieve 20in H2O oil mist pressure, ensuring not to exceed 65PSI – 4.48Bar Regulated Air Pressure. If regulated pressure does not increase with adjustments to air regulator. The air regulator is defective and should be replaced (LSC part no. 77780127).

4. If adequate mist pressure cannot be achieved with a functional air regulator, the capacity of the mist head has been exceeded. This situation occurs when the mist system is expanded to service additional equipment and bearings. If the oil mist system has been expanded, verify that the mist head vortex size is adequate for the service load. If the mist generating capacity has been exceeded, the vortex cartridge will need to be replaced to next larger size. See table in IVT Operating Instruction Manual section CONTROLLING THE MIST for part numbers, mist head sizes and replacement instructions.

HIGH MIST PRESSURE Oil Mist Header Pressure is above High Alarm Setting (30in H2O – 75mBar)

1. Confirm supply air ball valve for Auxiliary unit is closed. Main Unit and Auxiliary Unit cannot be operated at the same time.

2. Check for plugged reclassifiers. Paraffin based oils can develop a wax buildup through reclassifiers as the ambient temperature drops below freezing. Please refer to oil manufacturers product data sheet for oil specifications.

3. Check the oil mist distribution header and branch lines for sags or low points that can collect oil and obstruct the mist flow. Mist pipe blockages will result in a surging mist pressure

4. Verify that the regulated air pressure has not been changed from the original setting established at commissioning. When adjustments are made, the EVENT LOG records the event. See the section titled Event Log under LOCAL ALARMS, INDICATORS AND READOUT in the Installation and Operating Manual for instruction on how to access the event log. If it is determined that the regulated air pressure has been changed, and that the High Mist Pressure alarm is due the change in regulated air pressure correct the setting. Decrease the regulated air pressure to achieve 20in H2O oil mist pressure, ensuring not to decrease below 10PSI – .69Bar. If regulated pressure does not decrease with adjustments to air regulator. The air regulator is defective and should be replaced (LSC part no. 77780127). Note: Oil mist generating head will not produce oil mist with a regulated air pressure below 10PSI - .69Bar

5. If adequate mist pressure cannot be achieved while maintaining the minimum regulated air pressure, the system oil mist flow requirement is less than the minimum operating capacity of the mist head. This situation occurs when the mist system is reduced and equipment is removed from the system. If the oil mist system has been downscaled, verify that the mist head vortex size is correct for the service load. If the mist generating capacity is over capacity, the vortex cartridge will need to be replaced to next smaller size.
