7 OPERATING THE PUMP
This explains the function of the switch and the indicator lights on the pump controller.
SWITCH
POWER ON/OFF
(PUSH ON / PUSH OFF)
When switched off/on, it resets all system logic.
INDICATOR LIGHTS
SYSTEM (green)
The controller is switched on and the power source is
present. In low-power conditions, the light may show even if
there is not enough power to run the pump.
PUMP ON (green)
Motor is turning.
PUMP OVERLOAD (red)
See Troubleshooting section.
SOURCE LOW (red)
— not used in pool systems
The water source dropped below the level of the low-water
probe (or a probe connection failed). After the water level
recovers, the pump will restart, but this light STAYS ON until
the sun goes down or until power is interrupted or the
POWER button is reset off/on.
TANK FULL (red) —
not used in pool systems
Pump is turned off by action of the remote float switch circuit.
This circuit may also be actuated by a manual switch, timer,
thermostat, etc. Re-label it if necessary.
BATTERY SYSTEMS ONLY:
BATTERY LOW (tank light flashes)
Battery systems only
– battery voltage fell to 22V or 44V,
and has not yet recovered to 26V or 52V.
Starting the pump
Be sure there is not a closed valve or other obstruction in the water line. Switch on
the array disconnect switch in the junction box, and press the power switch on the controller. Leave the
switches on at all times, unless you desire to have the system off.
A solar-direct pump should start under the following conditions
1. clear sunshine at an angle of about 20° or more from the surface of the solar array
2. cloudy conditions, if the sunshine is bright enough to cast a very slight shadow
When sunshine is insufficient
In daylight, when sunshine on the array is too weak for the pump to
run, it will attempt to start about every 90 seconds. During each attempt, you will hear a slight noise in
the controller.
When pump runs slowly under very low sun conditions
In weak sun, the pump may spin slowly without moving much water. This is normal.
