8.2 Maintenance Overview
Electrical components require minimum attention and service. The
components that require service are the proximity switches on the intensifier
assembly, and the optical relay switch in the control panel.
8.2.1 Proximity Switch Service
If the pump quits pumping water, the proximity switch may need to be
replaced. Check the LED lights on the switch.
Symptoms of a failed proximity switch are (1) the LED lights do not change
state (indicating not sensing the piston) or (2) the LED lights are continuously
flashing. Replace the switch when failure occurs.
