Description
PDC panels control the operation of two pumps. The system includes a primary pump control float switch and an alarm float switch. LED indicators show power ON, pump run status, alarm status, and horn enable/ disable status. Operator pushbutton controls are available to manually run the pumps, to manually test the alarm, to disable or enable the alarm horn, as well as reset the system. Both pumps are individually protected with a manual reset fuse to isolate a failed pump.
When incoming fluid activates the primary pump float switch, the controller will energize one of the pumps. When water level in sump recedes, the pump will turn off when the primary pump float switch drops to the off position. Upon the next pumping cycle, the controller will activate the next pump in sequence providing a pumping redundancy for the system. The controller will continue to alternate pumps on each cycle.
If a pump fails to operate, the alarm will activate and the second pump will be called on to operate.
