    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
