SYSTEM TROUBLESHOOTING GUIDE
SYMPTOM
POSSIBLE CAUSE
CORRECTIVE ACTION
Water flow rate is not as
high as expected .
Motor/Pump is running backwards .
Switch two of the three wires leading from the controller to the
3-phase motor .
Pump capacity cannot supply the demand .
Use pump with higher flow rating (if head requirement is still
satisfied) .
Temperature in the controller is too high . If the
controller’s heat exchanger becomes too hot,
the controller will reduce the output frequency
to the motor to lower the power consumption .
Make sure there is at least 4 inches of room around the controller for
movement of air . Avoid direct sunlight . Reduce ambient temperature
below 104°F (40°C) . Increase input voltage if below 230 VAC .
Pump capacity cannot supply the demand .
Use pump with higher flow rating (if head requirement is still
satisfied) .
Excessive pressure
fluctuations .
Waterlogged tank .
Check tank for bladder damage . Replace if necessary .
Reset the tank pre-charge pressure (should be 70% of pressure
switch/transducer setting) .
Pressure tank is too small for flow rating of the
pump .
Use larger tank (4 gal . tank minimum) .
Motor runs continuously
with no flow demand .
Leak in the household or outdoor plumbing .
Check for leaky faucets, valves and/or pipe fittings and repair .
Leak in the pitless adapter .
Re-seat the pitless adapter . Replace seal as needed .
Drive will not come out of
standby mode
Bad pressure switch
Check continuity across pressure switch terminals and replace if
necessary
Loose pressure switch wire connection or
broken wire
Check pressure switch wire connections on display board and at
pressure switch . Check wire for continuity .
Drive is in switch control mode and transducer
is hooked up backwards .
Check to ensure transducer brown lead is connected to S1 and blue
lead is connected to S2 terminals . Change control mode from switch
to transducer .
