Cooler Pump Fault
P.32 — Pump 1 Fault
P.33 — Pump 2 Fault
Criteria for Trip
— The criterion is tested whether the units are
ON or OFF. This alarm will be generated if the cooler pump
interlock opens. When starting the pump, the control must read
an open circuit for 3 consecutive reads. If the pump is operating
and the circuit opens, the alarm will be generated immediately.
Action to be Taken
— The pump and machine will be shut
down. If there is another pump available, the control will start
that pump, restart the machine and clear the alarm. If no other
pump is available, the unit will remain OFF.
Reset Method
— Manual.
Possible Causes
— If this condition is encountered, check the
following items:
• Check the interlock wiring circuit.
• Check for a control signal to the pump controller.
• Check the cooler pump contactor for proper operation.
• Check control voltage for proper voltage. On 208-volt
systems, be sure the proper tap on TRAN1 is utilized.

Hi

turns out its the flowswitch!
they both sit on the same alarm !!!!p32-33
no seperate alarm for the flow!
i was wondering, this electronic flowswitch sends a signal via a resistor to a discreet input(ch15b) .
could this input be bridged??
thx for response
