PUMP SOLENOID LED STATUS INDICATOR
Refer to
Figure 3-2
. Two identical solenoids provide a margin of safety in the event that one of the solenoids fails
with its contacts closed. A two-color status indicator LED is located between the 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.
