Flow Transducers
Flow transducers are connected to return lines one through eight as well as the
facility water inlet line. The transducers monitor the flow rate of the cooling fluid
returning from your application and the facility water flow. Flows are displayed
on the controller's Operators Loop. If any flow rate drops below the setpoint,
entered in the controller's Setup Loop, a flow error message appears and a flow
alarm sounds.
NOTE:
If the setpoint is set to zero, the flow alarm is disabled.
Low Fluid Level Safety
If the reservoir fluid level drops to 20 gallons, a fault message is displayed on
the controller, the TROUBLE LED illuminates, and a remote signal alarm is
generated. The alarm has to be reset once the fault is cleared. If the level
drops below 16 gallons, the alarm sounds and the pump is de-energized.
Autorefill
The unit has a nominal evaporation rate of up to 2.5 gallons per day. Ensure
the autorefill system is installed.
If the reservoir fluid level drops below 20 gallons, the autorefill solenoid will
activate and fill the reservoir to approximately 22.5 gallons.
Emergency Off (EMO)
A guarded red mushroom shaped push-button switch with twist-to-reset is
provided in the front of the unit to turn off the unit in case of an emergency. The
button head is engraved with EMO in large white filled letters.
Activation of the EMO button will remove power from the main contactor coil
stopping operation of the unit.
Resetting of the EMO button will not restart the unit. After all hazards have
been removed and the EMO is reset, the unit must be reset by pushing the
PUMP ON button on the control panel.
