- Page 1 PCB-120 DC SUBMERISIBLE PUMP CONTROLLER USER’S MANUAL...
- Page 2 When used in a solar panel direct system it provides protection for the pump from over-voltage and over-current conditions and will provide current boosting in low sunlight conditions. PCB-120 SPECIFICATIONS 1 HP Input Voltage 100-180V (open circuit) (Eight Panels in Series Max)
- Page 3 WIRING THE PCB-120 SERIES CONTROLLER The PCB-120 Series controllers are limited to a maximum of eight 17 volt panels connected in series for the 120 volt systems. However, more panels may be connected in parallel. This controller has a 4 position preset input voltage selector switch designed for various solar module arrangements.
- Page 4 ELECTRODE CIRCUIT Switch #1 on the bottom dip switch is the electrode logic circuit. This circuit was designed to be used with three electrodes. A high-water, low-water, and ground electrode. With switch #1 in the ON position it becomes a low water cut-off circuit (well). This keeps the pump from running dry in a low yield well.
- Page 5 Switch #2 in the ON position allows the pump to run when terminals 7 and 8 are connected. This is generally used in conjunction with a float switch or a pressure switch which makes contact to run the pump. Switch #2 in the OFF position allows the pump to run when terminals 7 and 8 are disconnected.

4) Turn the small brass adjusting screw on the "Panel Voltage Adjusting Pot", located on the front of the controller, until the estimated voltage is obtained. 5) Return the panels to their normal position. The pump will then operate at its maximum output. - Page 7 IF THE RED AND GREEN LIGHTS ARE ON, WITH ALL OTHER LIGHTS OFF AND THE PUMP DOES NOT RUN: (IN GOOD SUNLIGHT) 4. Check for proper controller output voltage. Connect a DC volt meter across terminals 2 LD- and 3 LD+ on the large terminal block. If no voltage is indicated, check the fuse.
