iCON iSOLAR 4” PDP Instruction Manual
8a. Trouble shooting – cont.
The motor does not know specifically why it is unable to run. Its internal programming is
intended to protect the pump should it be unable to operate within its safe duty range.
External factors such as insufficient flow (water starvation, excessive head/torque, or
other blockages) can also cause the motor to shut down so check entire system to ensure
the issue is not related to valving or piping etc.
V3 Controller
The controller does not directly contribute to the behaviour of the motor once it is running.
Rather the controller monitors the power available from the solar array and adds a greater
level of protection by allowing various control inputs (low level float and discharge pipe
pressure switch or destination float.
Section 7a, Pages 17 and 18 explains the start and stop procedures. The LED’s on the
display provide visual indication as to the operational state of the controller/motor.
•
Check there is enough power at the controller (available Voltage and Amperage)
•
Check for loose or poor DC voltage connections
•
Check the inputs to the solar controller
To isolate the inputs - bridge the TWL (closed). Leave WWL open.
To eliminate the V3 iSOLAR controller as a possible cause of any unusual behaviour,
have a suitably qualified person connect the energy input from the solar array (DC) or
from a 240V AC power source directly to the motor.
