Alarm output signal
An alarm output signal is available.
Output transistor status indicates pump operation.
Output signal is activated if:
•
Stop (input signal 0.5 V - 2 V)
•
Stop (because of an alarm) (input signal 2 V - 10 V)
Output signal is not activated if:
•
Pump fault.
•
Running (input voltage < 0.5 V) (interpreted as cable break).
