SSV7 Troubleshooting
NO POWER TO THE DISPLAY
Power point is faulty; test power point with known working appliance, if the power point is operational,
check the controller with another power point and if there is still no display then send the controller for
repair.
PIPE/ROOF SENSOR FAULTS
The following are error messages caused by pool or roof sensor faults;
SENSOR DISCONNECTED OR OPEN CIRCUIT
Sensor cable unplugged from controller, cable damaged, bad cable join.
SENSOR SHORT CIRCUIT OR REVERSED
Sensor cable or cable join polarity is incorrect, the figure 8 wire has a white stripe to indicate the positive
side; the positive side of the wire should be wired to the right hand side when viewing the screws with
the figure 8 cable entry at the bottom of the plug. If the cable has been joined ensure no polarity reversal
occurs.
ISOLATING SENSOR FAULTS
Swap the sensor locations; simply put the pipe sensor in the roof socket and the roof sensor in the pipe
socket. If the fault moves from pipe to roof or vice versa then you can be certain that there is a sensor
fault. If the fault remains the same then the controller will need repairs.
For sensor open circuit faults, check for damage to the cable and repair if required. If no damage can be
found replace the sensor. If the cable runs underground or inspection is not possible then cut the sensor
from near the end of the cable and strip back the wires and join them, if the controller reports a short
circuit then the cable is fine, and you may replace the sensor end if re-routing a new cable is not possible.
For sensor short circuits, if the controller reports an open circuit when the cable is unplugged then
attempt reversing the cable polarity, replace the sensor if reversal is unsuccessful then the controller
requires repair, if the controller reports a short circuit while the cable is unplugged then the controller
requires repair.
