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.
TROUBLESHOOTING
PUMP DOES NOT RUN
If the pump does not run, first make sure the on/off switch is in the up
position. Then look at the row of lights to check the status of the system. 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.
1. Check wiring diagrams for proper connections. If the solar panel wires are
connected in reverse polarity the controller will short to ground. CAUTION: If a
battery system or a high amperage panel system is used and the polarity is
reversed, damage to the controller will result. This is not covered under
warranty.
If the motor polarity is reversed on a brush type motor the motor will simply
run backwards. If the polarity is reversed on an SCS brushless DC motor, a diode
in the motor will block any current flow. The result would be an open circuit
and this will not damage the motor.
2. Check for proper panel and controller voltage and current. If a DC volt and
amp meter is available, the best way to test for proper power is to check input
voltage and current and output voltage and current. This will indicate where to
start looking for the problem.
If a volt and amp meter is not available then a quick look at the indicator
lights will verify voltage coming from the panels going to the controller (red)
and power from the controller going to the pump (green). The other three lights
will also indicate the controller being turned off for low voltage (yellow),
over-current (orange) or a remote switch turn-off (amber).
If the red light is on and all other lights are off use a DC volt meter to check
for the correct open circuit voltage. Typical open circuit voltage ranges from
18 to 20 volts per panel. Multiply this per panel open circuit voltage times the
number of panels wired in series. Check to see if this calculated voltage
corresponds to the measured voltage.
For an array short circuit current test, disconnect the array wires from the
controller and short the wires together through a DC amp meter. Check this
current against the short circuit current rating of the solar panels. The
current in a series string should be the same as the rating for a single panel.
If the current in a string is low, run the same test for each individual panel
to identify the defective one.
3. Check for proper panel voltage set point. Make sure the proper panel
voltage selector switch is on for your panel arrangement. (Switches 4-6 on the
bottom, dip switch.) Note: if the incoming voltage is lower than the set point
voltage, the controller will not turn on.
