When the Cooler Pumps Sequence is configured, the cooler pump output will be energized when the chiller enters an ON mode. The cooler pump output is also energized when certain alarms are generat- ed. The cooler pump output should be used as an override to the external pump control if cooler pump control is not utilized. The cooler pump output is energized if a P.01 Water Exchanger Freeze Protection alarm is generated, which provides addition- al freeze protection if the system is not protected with a suitable antifreeze solution Circuit/Compressor Staging and Loading To configure this option with the Navigator displayThe dual chiller control algorithm has the ability to delay the start of the lag chiller in two ways. The Lead Pulldown Time parameter Lead Pulldown Type, LPUL is a one-time time delay initiated after starting the lead chiller, before checking whether to start an additional chiller. This time delay gives the lead chiller a chance to remove the heat that the chilled water loop picked up while being inactive during an un- occupied period. The second time delay, Lead/Lag Delay Lag Start Timer, LLDY is a time delay imposed between the last stage of the lead chiller and the start of the lag chiller. This pre- vents enabling the lag chiller until the lead/lag delay timer has expired Page Table 25 - Dual Master Chiller Control Parameters for Parallel Applications with Navigator Display Table 27 - Dual Slave Chiller Control Parameters for Parallel Applications with Navigator Display Table 29 - Dual Master Chiller Control Parameters for Series Applications with Navigator Display Default 1.0 F SPACE TEMPERATURE RESET - The control system is also capable of temperature reset based on space temperature SPT. An accessory sensor must be used for SPT reset 33ZCT55SPT. The Energy Management Module EMM is also required for temperature reset using space temperature Fig. 19 - Leaving Chilled Water Temperature Control Fig. 20 - Return Water Temperature Control Load Profile100 a30-4066 100 a30-4478Fig. 21 - Return Water Reset Fig. 22 - Space Temperature Reseta30-4479 a30-4481Fig. 23 - 4 to 20 mA Temperature Reset ResetSwitch Controlled Current Based - If using 2-step de- mand limit control, an energy management module must be installed. One-step demand limit control does not require the energy management module. Four parameters for 1-step switch control must be configured. For 2-step control, five parameters must be configured. The parameters are the type of Demand Limit Selection Demand Limit Type Select, DMDC, the setting for Switch Limit Set Point 1 Switch Limit Setpoint 1, DLS1, the setting for Switch Limit Set Point 2 Switch Limit Setpoint 2, DLS2, the Current Limit Select Current Limit Select, CUR.S, and the Compressor Current limit at 100% signal, Current Limit at 100%, CUR.F mA Demand Limit Signal Fig. 24 - 4 to 20 mA Demand Limit CapacityLimit DemandAlarm Control Fig. 25 - 4 to 20 mA Demand Limit Compressor CurrentTable 32 - Daylight Savings Time Configuration Fig. 26 - Alarm Routing ControlDESCRIPTION STATUSTable 33 - Capacity Control Overrides Override #14 Slow Change Override - This override pre- vents compressor stage changes when the leaving temperature is close to the control point and slowly moving towards it System Check PRE-START-UPTable 34 - 30XW Compressor Nominal Capacity Operating Limitations START-UPTable 35 - Temperature Limits for Standard Units Pressure DropEvaporator Flow Rate Pressure Drop Evaporator Flow RatePressure Drop Evaporator Flow RateFig. 30 - 30XW325-400 Evaporator NIH Flange A30-4693Drop PressureCondenser Flow Rate Pressure DropPressure Drop Condenser Flow RateFig. 34 - 30XW150-200 Condenser NIH Flange Fig. 35 - 30XW325-400 Condenser NIH FlangePressure Drop Condenser Flow RatePressure Drop Condenser Flow RateDual Chiller Sequence of Operation - With a OPERATIONTable 37 - 30XW Operating Modes 3, 5 of the month.
