I/O DESCRIPTIONS Analog Input #1: Analog Input #1 reads the 4-20 ma signal from the level probe. Analog Output #1: Analog Output #1 is a 4-20 ma output signal that is equivalent to the input level signal. This output is used to interface to PLC plant control systems. Analog Output #1 is an electronically repeated level input signal. It does not have direct interface to the microprocessor and therefore cannot be calibrated. Analog Output #2: Analog Output #2 is a 4-20 ma output that controls motorized liquid feed valve #1. Analog Output #3: Analog Output #3 is a 4-20 ma output that controls motorized liquid feed valve #2. Digital Input #1: Switched input, connected to the high level shutdown float switch or to an electronic level switch. If this input is energized, it is OK to run. If this input is de-energized, a high level shutdown is indicated on the screen and Digital Output #7 is de-energized. Digital Output #1: Alarm output When an alarm condition occurs, the alarm output is turned off. On in normal mode. Digital Output #2: Low level alarm output. When in the recirculator mode, this output is energized on low level alarm. Off in normal mode. Digital Output #3: Liquid feed solenoid #2 when in the following modes: Intercooler. Accumulator. Surge Drum. Recirculator. Vent solenoid when in the transfer system mode. Energized when feeding liquid or venting. Off when not feeding liquid or venting. 6

Digital Output #4: Liquid feed solenoid #1 when in the following modes: Intercooler. Accumulator. Surge Drum. Recirculator. Hot gas solenoid when in the transfer system mode. Energized when feeding liquid or hot gas. Off when not feeding liquid or hot gas. Digital Output #5: Liquid transfer solenoid/pump output. Energized when transferring. Off in normal mode. Digital Output #6: High level alarm. Energized when in alarm. Off in normal mode. Digital Output #7: High level shutdown. This output is wired directly to Digital Input #1 and is not controlled by the microprocessor. Therefore if the high level shutdown float switch trips, this output trips immediately. An external timer is required to prevent false trips to the compressors. 7

INTERCOOLER, ACCUMULATOR, SURGE DRUM & RECIRCULATOR OPERATION LEVEL CONTROL: The diagram below shows a vessel with liquid in it. A level probe reads the level and transmits the signal to the controller. The controller determines the level in comparison to the desired set-point, and if lower than set-point, energizes the liquid solenoid until the liquid level reaches the set-point. Once set-point is reached, the liquid solenoid is turned off. The signal from the level probe needs to have offset calibration so that the indicated level is the same as the actual level. A calibration screen allows the operator to input a (+/-) variable to correct the level input signal. The level value is then displayed on the operator interface and is also made available on Analog Output #1 as a 4-20mA signal and transmitted through the serial communications port. Level probe Solenoid Liquid The control algorithm is a simple servo feedback loop incorporating Proportional control as shown in the following diagram. 8

Level probe Liquid make-up Solenoid Analog in Controller Digital out The analog value is read from the level probe and compared to the set-point entered by the operator. If the level is at set-point or higher, the output remains off and the solenoid is closed. If the level drops below the set-point plus dead band, the output is turned on and the solenoid is opened. The output remains open until the level reached the set-point. A small dead-band is placed at set-point (1%) so that the solenoid cannot chatter. An example would be if the operator set the desired level at 40%. The solenoid would close at 40% and open at 39%. If there is a High Level Alarm, the liquid feed solenoid is de-energized. The liquid feed solenoid stays closed after a High Level Alarm until the level drops below the operating level. Once below the operating level, the liquid feed solenoid is re-energized under control of the liquid level control set-point. When the OFF mode is selected, the liquid feed solenoid is closed and remains closed until the ON is selected and the level is below set-point. When there is a Low Level Alarm the liquid feed solenoid continues to operate to get the vessel level back to normal operating level. Dual liquid make-up solenoids can be employed to optimize for full load and part load conditions. The two solenoids can be the same size or one larger than the other. The software would be configured so that the solenoids would be energized in a two-stage configuration. Using the previous example, where the set-point is at 40%, solenoid #1 would open when the level drops to 39%. Solenoid #2 would open when the level dropped to 34%. At this point, both solenoids are open and feeding liquid to the vessel. When the level begins to rise, the #2 solenoid would shut off at 35% and the #1 solenoid would shut off at 40%. If there is a High Level Alarm, the liquid feed solenoids are de-energized. The liquid feed solenoids stay closed after a High Level Alarm until the level drops below the operating level. Once below the operating level, the liquid feed solenoids are re-energized under control of the liquid level control set-point. 9

When the OFF mode is selected, the liquid feed solenoids are closed and remains closed until the AUTO mode is selected and the level is below set-point. When there is a Low Level Alarm, the liquid feed solenoids continue to operate to get the vessel level back to normal operating level.. Level probe 2 Solenoids Liquid MOTORIZD LIQUID FEED VALVES A variable motorized valve can be substituted for a liquid make-up solenoid. The variable valve has the advantage of feeding liquid at full flow or part load. Motorized valves eliminate the liquid hammer effect from solenoids. True P-I-D control can be used with the motorized valve where only the proportional part of the P-I-D control can be used with the solenoid. The microprocessor controller outputs a 4-20mA signal to drive the valve. Level probe P-I-D Liquid make-up motorized valve Analog in Controller Analog out 10

The analog value is read from the level probe and compared to the set-point entered by the operator. The software is configured so that the valve opens proportional to the difference in level from set-point. An example would be if the operator set the desired level set-point at 40%, the valve closed set-point at 0% difference and fully open set-point at 10% difference. If the level is at set-point or higher, the analog output remains at 4 ma which drives the motorized valve closed. If the level drops below set-point, each 1% drop, opens the valve 10%. When the vessel level drops to 30%, the valve is at 20 ma and is fully open. Level probe Motorized valve Solenoid Liquid A solenoid must be included with the motorized valve. The reason for the solenoid is that it acts as a back-up safety device in case the motorized valve sticks open or fails operate. The controller will close the solenoid when the level reaches the SOL OFF DIFF set-point, regardless of the motorized valve position. In addition, some valves may not close during a power failure, allowing liquid to continue to flow into the vessel, possibly over filling it. The solenoid assures liquid shutoff. The software, under normal operation, would energize the solenoid when the AUTO mode is selected and de-energized when the OFF mode is selected. If there is a high level alarm the solenoid is de-energized. If there is a High Level Alarm, the liquid feed solenoid is de-energized. The liquid feed solenoid stays closed after a High Level Alarm until the level drops below the operating level. Once below the operating level, the liquid feed solenoid is re-energized. The motorized valve then takes over control of the liquid level. When the OFF mode is selected, the liquid feed solenoid is closed and remains closed until the AUTO mode is selected. The motorized valve is also driven closed when the OFF mode is selected and remains closed until the AUTO mode is selected. 11

When there is a Low Level Alarm, the liquid feed solenoid and motorized valve continue to operate to get the vessel level back to normal operating level. When the vessel level rises to the Liquid Transfer ON set-point, the transfer pump/solenoid output is energized. When the vessel level drops to the Liquid Transfer OFF set-point, the transfer pump/solenoid output is de-energized. Two motorized valves can be incorporated where they can be set up as a two stage system. Level probe motorized valves Liquid Operation is similar to the previous example, except that valve #1 operates from 0 to 10% deviation from set-point. Valve #2 would operate from 10% to 20% deviation from set-point. 12

TRANSFER SYSTEM OPERATION LEVEL CONTROL: The diagram below shows a transfer vessel with liquid in it. A level probe reads the level and transmits the signal to the controller. The controller determines the level in comparison to the transfer set-points and decides whether to begin liquid transfer, end liquid transfer or wait. The signal from the level probe needs to have offset calibration so that the indicated level is the same as the actual level. A calibration screen allows the operator to input a (+/-) variable to correct the level input signal. The level value is then displayed on the operator interface and is also made available to be transmitted through the serial communications port. Vent Solenoid Level probe Hot Gas Solenoid Transfer Solenoid Liquid When the vessel is not in the transfer mode, the outputs are in the following states: o Vent solenoid = open o Hot Gas solenoid = closed o Transfer pump/solenoid = off/closed When the level in the vessel rises to the Liquid Transfer ON set-point, the following sequence occurs: o Close Vent solenoid o Time delay = 3-5 seconds o Open Hot Gas solenoid o Time delay = 5-10 seconds o Energize transfer pump/solenoid. 13

When the level in the vessel drops to the Liquid Transfer OFF set-point, the following sequence occurs: o De-energize transfer pump/solenoid. o Time delay = 5-10 seconds o Close Hot Gas solenoid o Time delay = 3-5 seconds o Open Vent solenoid. When the OFF mode is selected, the vent solenoid remains open and the Hot gas and transfer outputs are turned off. 14
