(If a battery system is used and the polarity is reversed, damage to the controller will result). Check for proper panel, controller, and/or battery voltage with a volt meter. A quick look at the indicator lights will verify power from the panels going to the controller (red) and power from the controller going to the pump (green). If the over-voltage fault light (yellow) is on, the controller will not turn on. This indicates the incoming voltage is too high for the voltage setting selected on the six-position dip switch. Check the chart and select the proper switch. If the red light is on and the green wires at the terminal block and make For an additional pump test, connect LD-, this will bypass the controller direct. light is not, disconnect the float switch sure switch #5 is off and switch #6 is on. a jumper wire across terminals 5 PV- and 6 and will allow the pump to run panel IF BOTH THE RED AND GREEN LIGHTS ARE ON 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: 3. 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. ) Note: If no voltage is seen at terminals 6 (LD-) and 7 (LD+) then: 6. 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 1-4 and turn switch #6 on and #5 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.
