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.
CONTROLLLER ADJUSTING PROCEDURE
CAUTION: A QUALIFIED SOLAR ELECTRIC TECHNICIAN SHOULD ONLY PREFORM THIS
PROCEDURE. 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. It is only for positive displacement type pumps.
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.
(Option 1) For Panel voltage adjustment at the maximum power point.
1. 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. This
puts the controller in a current boosting mode so this adjustment can be made.
2.
Connect a DC volt meter to the pump side of the controller. (LD+ and LD-)
3.
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.)
4.
Return the panels to their normal position. The pump will then operate at
its maximum output.
(Option 2) For estimated panel voltage adjustment.
1) 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.
2) Connect a DC volt meter to the panel side of the controller. (PV+ and PV-)
3) Estimate the proper voltage by multiplying the voltage rating of the panel’s
times the number of panels connected in series and deduct 20%.
Example:
8-60 Watt panels @ 17.1 Volts ea. = 137 Volts - 20% = 110 Volts
