Electronic Expansion Valve (EXV) Board —

Electronic Expansion Valve (EXV) Board —

The 30XW150-325 units have one EXV board. The 30XW350,400 units have one EXV board per circuit. See Fig. 10. The board is responsible for monitoring the suction gas temperature and economizer gas temperature thermistors. The board also signals the main EXV and economizer EXV (ECEXV) motors to open or close. The electronic expansion valve board responds to commands from the MBB and sends the MBB the results of the channels it monitors via the LEN (Local Equipment Network). See below for DIP switch infor- mation. See Tables 6 and 7 for EXV inputs and outputs.

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 To configure this option with the Navigator display Circuit/Compressor Staging and LoadingThe 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.

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.
