Caretaker Ultra Flex 2 8-Port Controller PCB
The Controller PCB has all the connection points for the Direct Burial Cable, Pressure Switch Assembly, Rotary Switch, L.E.D., and Transformer. The Controller PCB communicates with the Sensor PCB to let the system know when to switch stations. If the L.E.D. does not flash on power up, the Conroller PCB is damaged.
