state-of-the-art chiller protection. The system controls cooling load within the set point plus and minus the dead band by sensing the water or brine temperature and regulating the inlet guide vane via a mechanically linked actuator motor, and regulating VFD (variable frequency drive) speed if the compressor is powered by a variable speed drive.

Sensors Controls Outputs PRESSURE TRANSDUCERS — Pressure transducers measure and control the pressures in the unit. These electronic sensors deliver 0 to 5 VDC. The transducers can be calibrated through the controller. The pressure transducers are connected to the IOBs. See Table 6. EVAPORATOR/CONDENSER WATER PUMP — The controller can regulate an optional evaporator/condenser water pump.
SCREENS — The Human Machine Interface includes the following screens: • Welcome screen • Home screen, which displays the main parameters • Menu screens for navigation • Data/configuration screens, which list the parameters by type • Operating mode selection screen • Password entry and language selection screen • Parameter modification screen • Time schedule screen If the interface is not used for a long period, it goes into screensaver mode and displays a black screen.
When a start-up mode is selected, a status screen displays the progress of the start-up sequence (Fig. 18). Messages — The Set Point screen, On/Off screen, User Login screen, and Main Menu screens described in the next sections may display status messages at the bottom of the screen. See Table 9.

The control then waits until the oil pressure (OIL PRESS VERIFY TIME, operator-configured, default 40 seconds) reaches a maximum of 18 psi (124 kPa). After oil pressure is verified, the control waits 40 seconds for oil prelube, and the compressor start relay energizes to start the compressor.

If decreased capacity is needed, the control first tries to decrease VFD TARGET SPEED if it has not reached the minimum VFD speed; if the minimum VFD speed has been reached, the control decreases IGV TARGET POSITION instead. See Fig. 35. From the compressor relay closed point to the end of ramp loading, the VFD TARGET SPEED is the configured VFD start-up speed.

If the DEMAND LIMIT SOURCE exceeds the ACTIVE DEMAND LIMIT by 5% or less, capacity will be inhibited. If the DEMAND LIMIT SOURCE exceeds the ACTIVE DEMAND LIMIT by more than 5%, capacity will be decreased. Alternatively, the limit may be applied by by AUTO DEMAND LIMIT INPUT, an optional 4 to 20 mA input.
at any time. If the controller is replaced, one opportunity before the first start-up with the new controller is provided to set COMPRESSOR ONTIME and TOTAL COMPRESSOR STARTS to the last readings retained with the prior controller. The chiller also maintains a start-to-start timer and a stopto-start timer. These timers limit how soon the chiller can be started and are displayed on the system overview (home) and RUN TIMES screens.
PIC5 control system to allow PIC5 control for the water pumps and cooling tower fans (high speed and low speed). The cooling tower fans are controlled by the pressure difference between condenser and evaporator and entering water temperature of condenser. The objective is to maintain the entering condenser water temperature in the optimal range.

Oil Filter Alert — This function is active only in an oil pump control test. If the oil pump is forced to ON and after 10 seconds, if the pressure differential between oil pump pressure and oil discharge pressure is lower than the threshold set in the Oil Filter Pres Diff field, the filter needs to be replaced and the dedicated alert 160 is reported until the oil pressure differential is higher than the alert threshold plus 2 psig. Then set the Oil Filter Change Done option to YES manually.
A manual reset must be run from the main menu via the ALARMRST menu, item RST_ALM. Once the alarm has been corrected or reset, all information regarding solved alarms is stored in the Alarm History. See Appendix A, page 94. Alert Codes — Table 16 lists PIC 5 alert codes. These are automatically reset when the situation returns to normal.
