9 TROUBLE SHOOTING
Please read this section before calling for help.
If you call for help, please refer to the model and serial numbers.
IF THE CONTROLLER MUST BE REMOVED FOR REPAIR OR REPLACEMENT –
Remove the wires and flexible conduit from the controller and remove the CONTROLLER ONLY.
LEAVE THE JUNCTION BOX IN PLACE.
9.1 If The Pump Doesn’t Run
Most problems are caused by wrong connections (in a new installation) or failed connections, especially
where a wire is not secure and falls out of a terminal. Please follow these instructions before calling for
help.
The
System ON
light will indicate that system is switched on and power is available. This indicates that
the connection to the power source is probably correct. It indicates that VOLTAGE is present. There may
not be sufficient power to start the pump, but it should attempt to start at intervals of about 1 minute.
Pump attempts to start every 60-90 seconds but doesn’t run
The controller makes a slight noise as it tries to start the pump. The pump will start to turn or just vibrate
a little.
1. There may be insufficient power reaching the controller. A solar-direct (non-battery) system
should start if there is enough sun to cast a slight shadow. A battery system should start if the
supply voltage is greater than 22V (24V system) or 44V (48V system).
2. If the pump was recently connected (or reconnected) to the controller, it may be running in
reverse direction due to wiring error. See Section 4.7. Running in reverse may cause the impeller
to unscrew from the shaft.
3. If the motor shaft only vibrates and will not turn, it may be getting power on only two of the three
motor wires. This will happen if there is a broken connection or if you accidentally exchanged one
of the power wires with the ground wire.
4. The pump or pipe may be packed with sediment or debris.
PUMP OVERLOAD
This red light indicates a serious fault. The motor cannot turn freely due to a
mechanical cause or a short circuit. To attempt to restart the pump, disconnect the power for at least 8
seconds.
9.2 Inspect The System
Many problems can be located by simple inspection. No electrical experience is required for this.
Inspect the solar array
1. Is it facing the sun? (See solar array orientation, Sections 3.4 and 3.5.
2. Is there a partial shadow on the array? If only 10% of the array is shadowed, it can stop the
pump!
Inspect all wires and connections
1. Look carefully for improper wiring (especially in a new installation).
2. Make a visual inspection of the condition of the wires and connections. Wires are often chewed
by animals if they are not enclosed in conduit (pipe).
3. Pull wires with your hands to check for failed connections.
