PUMP SOLENOID LED STATUS INDICATOR
Refer to
Figure 3-2
. Two solenoids provide a margin of safety if one of the solenoids fails with its contacts closed.
A status two-color indicator LED is located between the two 8A circuit breakers to monitor the condition of the two
solenoids. The LED is normally off when the pump is not operating and becomes green when the pump operates.
When the pump is not operating and the top solenoid has failed the LED will be red. The LED will be green when
the side solenoid has failed.
