Pumping Alarm Condition – On Primary Power
The controller monitors a "pumping alarm condition" where a pump is called to run and the liquid level continues to rise
and goes above the Alarm Float switch. If a pumping alarm condition occurs three or more of the last five times a pump is
called to run, the pump indicator will blink indicating system components should be checked. Any of the following
conditions could cause a pumping alarm condition:
1) A pump fails to operate
2) The Alarm Float switch stays (mechanically stuck) in the closed (on, or up) position.
3) There is a problem (blocked or leak) in the out-flow plumbing
4) The water in-flow rate is greater than the pump-out rate
5) The Primary Float switch stays (mechanically stuck) in the open (off, or down) position.
A blinking light indicates a component failed and service is required. To assist the service technician the controller will
indicate which component has failed.
