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

Description
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.
