Programming Established Alarm And Control Set Points The LubriMist® Model IVT Oil Mist Generator is shipped with standard preset values for each of the monitored variables. However established control and alarm set points can be established to meet particular operating needs. All established set points are made with the key pad located in the operator compartment. . By pressing the [SET] and any key sequence any of the control or alarm settings can be changed. Any number of operating variables may be changed, and they may be addressed in any order. Exiting can be done at any time and will effect only those settings that have been "entered" while in the program mode. Pressing the ENTER key logs a value into memory. The controller will only accept new values that are between the factory established high and low settings. The programming mode therefore, allows the to establish a narrower alarm band around a set point within the minimum and maximum allowable values. The following table lists the range within which the can set limits to suit operating variables.

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 indicators, 2) fault message readout on the liquid crystal display and, 3) red and green externally mounted unit status lights.


Page 95 of 221

LED 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 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.

WARNING

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. Liquid Crystal Display Identifies Any Fault Condition And The Current Operating Condition.

Data and Event Log Within the operating program of the IVT controller, the microprocessor polls all operating variables at a specified time interval. All input signals are then scaled according to the selected unit of measure and then posted into the Data Log. As data is posted and accumulated, the result is a historical record of how the IVT Oil Mist Generator operated over the time. Once the data table is full, the most aged record is dropped and the most recent record is added. The data log contains a maximum of 2043 records posted at one-hour intervals. The data log is accessible through the serial data port. Additionally, an Event Log is also generated and held in memory. The event log is a record of all alarms, adjustments and reset events. The all events are posted chronologically, and recorded with a date – time stamp. The event log is also accessible the serial data port. For additional information see Event the section titled LOCAL ALARMS, INDICATORS AND READOUT. The IVT data communication port transmits an ASCII data string when an address character is received. The address to send characters are as follows. 1. To transmit the EVENT LOG, send address character “e” to RX input 2. To transmit the DATA LOG, send address character “d” to RX input

Page 111 of 221


Page 112 of 221

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 ’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 . 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. 2. 3. 4.

Enable Modbus communication via the dipswitch. Connect the IVT to the host computer through an RS232 ÍÎ RS422/485 converter. Configure the Modbus feature via the IVT control . 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 ÍÎ RS-422/485 interface converter is required to link to the IVT communication port. The RS-232 ÍÎ 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 has 24 Setpoints 04 Input has 13 Anaputs 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 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, D13, 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 s, 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. Disconnect button Address (HEX) & Length

Figure 3 Message frame In the Modscan screen there will be 2 sets of numbers in the shaded areas called the (Message Frame). The first set of numbers will be in a light gray area and the second set of numbers will be in a black area, these are the default colors for the Modscan screen. See figure 4

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.

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 s or Input s. 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.

0 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 s or Input s 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 s that may need to represent values below zero. Fifteen integer bits plus sign allow for numeric values in the range –32768 to +32767. 15 S

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. Signed Decimal Number -32,768 -32,767 -1 0 1 32,766 32767

16-bit Twos-Complement Representation Binary Decimal Hexadecimal 1000000000000000 32768 8000 1000000000000001 32769 8001 1111111111111111 65535 FFFF 0000000000000000 0 0000 0000000000000001 1 0001 0111111111111110 32766 7FFE 0111111111111111 32767 7FFF

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 anaput or set point are an exact replica of what is seen on the control 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 . 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

Page 128 of 221


Page 129 of 221


Page 130 of 221

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. 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 clockwise 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.

WARNING

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

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 . The controls for the auxiliary oil mist generator are located on the right side of the operator . 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 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 . Also located on the operator 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.


Page 135 of 221

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 es 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).

Ensure That The Air Supply Block Valve For The Oil Transfer Pump Is In the Open Position

Open The Auxiliary Oil Mist Generator Air Supply Block Valve Before Filling The Reservoir. Use The Air Pressure Regulator To Limit The Oil Transfer Pump Cycle Speed To 200 Cycles Per Min. The Right Toggle Valve Opens Oil Flow Into The Auxiliary Oil Mist Generator Reservoir The Left Toggle Valve Controls The Air Supply To The Transfer Pump Monitor Oil Level In The Oil Level Gauge. Fill To 2/3 Full. Ensure That The Drain Valve Is Closed And Plugged.


Page 136 of 221

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 . 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 . 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 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 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 s 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.

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 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. b) For ATEX configured units, power is supplied through a three-position selector switch. To turn power OFF to the auxiliary unit move the selector switch to the center position.( I O II ) 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 . The volume of oil mist is proportioned to each bearing or application point by the reclassifier. With the air by 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.

Air Pressure Regulator To Control Auxiliary Oil Mist Generator Mist Volume

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 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.

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 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 by) 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. Oil Flow Valve

4. The AIR BY- 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- 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- 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

Air By- Valve

IMPORTANT: The oil / air ratio or mist density is reduced by opening the air by valve. However, oil output is not affected.

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.

Page 150 of 221

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 by 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 151 of 221

e) Check and 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.

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, 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.

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. 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, 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. See table in IVT Operating Instruction Manual section CONTROLLING THE MIST for part numbers, mist head sizes and replacement instructions.
