[. . . ] If you need to change the voltage set point the "panel voltage adjusting pot" will allow you to do so. CAUTION If you change the voltage setting using the adjusting pot, it will change the set points on all 4 selector switches.

[. . . ] 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. This is generally used in conjunction with a float switch which breaks contact to make the pump run. 12/6/1999 4 CONTROLLER ADJUSTING PROCEDURE CAUTION: THIS PROCEDURE SHOULD ONLY BE PREFORMED BY A QUALIFIED SOLAR ELECTRIC TECHNICIAN. THIS PROCEDURE IS NOT NECESSARY IF STANDARD 16. 5 TO 17 VOLT SOLAR MODULES ARE BEING USED. This procedure will not work on a centrifugal type pump such as an SCS submersible. The purpose of this procedure is to adjust the voltage of the PV array to its peak power point and thus obtain the maximum water delivery from the pump. This procedure should be performed with the panels at their normal operating temperature at mid-day. With the system installed and pumping water, turn the panels away from the sun until the pump flow rate is reduced by approximately 50%. If this is not possible then shade the panels slightly until you have obtained the same results. This puts the controller in a current boosting mode so this adjustment can be made. (LD+ and LD-) Turn the small brass adjusting screw on the "Panel Voltage Adjusting Pot", located on the front of the controller, until the highest possible voltage is obtained. (If this controller is used on a Jack Pump system using a flywheel, there will be a slight delay from the time you make an adjustment to when a change in voltage will be noticed. ) Return the panels to their normal position. With the system installed and pumping water, turn the panels away from the sun until the pump flow rate is reduced by approximately 50%. If this is not possible then shade the panels slightly until you obtain the same results. (PV+ and PV-) Estimate the proper voltage by multiplying the voltage rating of the panel's times the number of panels connected in series and deduct 20%. = 103 Volts - 20% x (103 Volts) = 82 Volts 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. 3. 4. 5. 12/6/1999 5 TROUBLESHOOTING PUMP DOES NOT RUN If the pump does not run, first make sure the on/off switch is in the up position. The red light (indicating power in) and the green light (indicating power out) are the only ones that should be on. All other lights indicate that the controller has been turned off for a specific reason. If the solar panel wires are reverse polarity the controller will short to ground. CAUTION: system or a high amperage panel system is used and the polarity damage to the controller will result.
