NOTICE:
Equipment damage!
If the microprocessor calls for a pump to start and water does not flow, the evaporator may be
damaged catastrophically. It is the responsibility of the installing contractor and/or the
customer to ensure that a pump will always be running when called upon by the chiller controls.
When going from Stop to Auto, the EWP relay is energized immediately. If evaporator water flow
is not established in 4 minutes and 15 seconds, the CH530 de-energizes the EWP relay and
generates a non-latching diagnostic. If flow returns (e.g. someone else is controlling the pump), the
diagnostic is cleared, the EWP relay is re-energized, and normal control resumed.
If evaporator water flow is lost once it has been established, the EWP relay remains energized and
a non-latching diagnostic is generated. If flow returns, the diagnostic is cleared and the chiller
returns to normal operation.
NOTICE:
Equipment Damage!
Do NOT enable/disable the chiller by removing water flow or equipment damage can occur.
In general, when there is either a non-latching or latching diagnostic, the EWP relay is turned off
as though there was a zero time delay. The relay continues to be energized with:
A Low Chilled Water Temperature diagnostic (non-latching) unless also accompanied by an Evap
Leaving Water Temperature Sensor Diagnostic.
or
A Loss of Evaporator Water Flow diagnostic (non-latching) and the unit is in the AUTO mode, after
initially having proven evaporator water flow.
Note:
If pump control is used for freeze protection then the pump MUST be controlled by the
CGAM CH530 control. If another method of freeze protection is used (i.e. glycol, heaters,
purge, etc) then the pump may be controlled by another system.
Chilled Water Pump Control - Field Supplied Dual Pumps
CH530 can provide pump control for two customer-supplied pumps, as long as the pump contactor
coils 1A9 and connect the pump fault feedback signals 1A12 are properly connected.
In this situation, the unit will leave the factory with Evaporator Pump Control (EVPC) = No Pump
Control (Pump Request Relay) (NPMP) and Evaporator Pump Fault Input (EVFI) = Installed
(INST).When the contactors and pumps are set up in the field, the CH530 Service Tool (TechView)
must be used to reconfigure to Evaporator Pump Control = Dual Pump Fixed Speed and Evaporator
Pump Fault Input = Not Installed or Installed depending on how the fault feedback wire is
connected. It is strongly recommended to install the Fault Input if possible as the controls will “hot-
