[. . . ] 9. ) High water cut-off circuit with adjustable set points. 11. ) Pre-adjusted panel voltage settings from a DIP switch. (OPTIONAL) 7/19/1999 2 13. ) Reversible logic for electrode circuit. 14. ) Reversible logic for the remote cut-off switch WIRING THE PC SERIES CONTROLLER CAUTION: Reverse polarity on a battery system or a panel system capable of producing over 10 amps will damage the controller. WIRE TERMINAL DESCRIPTION WITH DIP SWITCH #6 OFF: High water cut-off (tank fill-up) 1) LO LOW WATER LEVEL SENSOR turns the pump off. (Mount an E-1s electrode 2" above the ground sensor. ) 2) HI HIGHWATER LEVEL SENSOR turns the pump off. (Mount an E-1s brass electrode at the desired turn-off point. ) WITH DIP SWITCH #6 ON: (Low water cut-off) 1) LO LOW WATER LEVEL SENSOR turns the pump off. (Mount an E-1s electrode 2" above the ground sensor. ) 2) HI HIGH WATER LEVEL SENSOR turns the pump on. (Mount an E-1s brass electrode below the static water level at the desired turn-on point. ) 3) GN GROUND OR COMMON WATER SENSOR must be in the water RS- at all times. [. . . ] The pump will then operate at its maximum output. 7/19/1999 4 TROUBLESHOOTING PUMP DOES NOT RUN 1. Check wiring diagrams for proper connections. Check for proper panel voltage with a volt meter. A quick look at the indicator lights will verify power coming from the panels going to the controller (red), power from the controller going to the pump (green) and overcurrent turn-off (yellow). If the red light is on and the green and yellow light is not, make sure the switch is on, disconnect the remote switch wires and electrode wires, if used, and turn switch #5 and #6 off. If the green light is still not on disconnect the pump wires, LD- and LD+. If the green light does not turn on then check voltage on LD- and LD + with a volt meter to confirm no output voltage. For an additional pump test, connect a jumper wire across terminals 5 PV- and 6 LD-, this will bypass the controller and will allow the pump to run panel direct. Note: You must have full or almost full sun for this test to be valid. Make sure the proper voltage selector switch is turned on for your panel or battery arrangement. Note: If the incoming voltage is lower than the set point voltage, the controller will not turn on. IF THE RED AND GREEN LIGHTS ARE ON, WITH YELLOW OFF AND THE PUMP DOES NOT RUN Note: To verify power coming out of the controller, connect a DC volt meter across terminals 6 LD - and 7 LD + . If 12 volts or more is coming out then: 1. Check the splice above the pump for proper connections. Check for a broken wire leading to the pump. (With an ohmmeter set on the R x I scale check between the two pump wires. Meter reading should be between . 5 and 50 ohms. If the resistance is higher than this, disconnect the pump at the splice above the pump and check again. ) 7/19/1999 5 IF NO VOLTAGE IS SEEN AT TERMINALS 6 LD- AND 7 LD, THEN: 1 Make sure the switch is turned on. Check to see if the water level is above the top electrode when the low water cut-off circuit is being used, or below the bottom electrode when the high water cut-off circuit is being used. (To bypass all remote switching circuits, disconnect wires from terminals 3 and 4 and turn switch #5 and #6 off). Check the controller for proper adjustment. If the voltage setting on the controller is higher than the incoming voltage, the controller will not turn on. Check to see if the float switch, if used, is functioning properly.
