General
The S-Drive and Aquavar SPD drive are self-diagnosing controllers. If a problem occurs, observe the Status Code
Indicator Light on the front of the unit. No Status Code Indicator Light means either no or low input voltage (less
than 140Vac).
Danger
Status Code Indicator Light is not a voltage indicator! Always turn off disconnect switch
and circuit breaker and wait 5 minutes before servicing. High voltage may still remain on
controller.
Refer to the status code label on the side of the controller access cover to diagnose system errors.
See the following diagram.
Use the following table to help troubleshoot problems.
No Light
Controller Status Description
Low/No Input Voltage Check the input voltage to the controller. Measure the input voltage
between phases using an AC Voltmeter. This voltage should be
greater than 140Vac for the status indicator light to turn on.
Green Light Codes
Flashes Controller Status Description
Constant Standby Constant Green Light indicates the pump is off. The system is in
Standby mode when there is no flow in the system and the pressure
setting has been reached or the RUN/STOP input is set to STOP (open
switch) between #2 and #1.
Blinking Pump Running Flashing Green Light indicates the pump is running.
Red Flashes Fault Code Restart Action
Constant Replace Controller Controller will not restart. Power must
be reset to clear the fault.
2 Blinks No Water/Loss of Prime Controller will restart automatically
according to the No Water Restart Time
switches (switches 3&4 of bank 2).
3 Blinks Sensor Fault Controller will restart automatically when
the sensor signal is within the valid
operating range.
4 Blinks Pump or Motor Bound Controller will restart automatically 5
times. After 5 faults the power must be
reset to clear the fault.
5 Blinks Short Circuit/Ground Fault Controller will not restart. Power must be
reset to clear the fault.
6 Blinks Input Phase Loss Controller will restart automatically 5 times.
After 5 faults the power must be reset to
clear the fault.
7 Blinks Temperature Controller will restart automatically when
temperature is within the operating range
of the controller.
8 Blinks Over Voltage Controller will restart automatically when
the input voltage is within the operating
range of the controller.
9 Blinks Motor Overload Controller will restart automatically.
