Troubleshooting Error Codes
The status light which is visible through the cover label is used to indicate the system status i.e. running, stopped or
faulted. When faulted, the status light will be Red. The error code is the number of flashes followed by a 1 second
pause. The number of flashes can be from 2 to 9. The error code will be repeated until the fault is cleared. The
following describes the various errors:

7: TROUBLESHOOTING
NO LIGHT
Flashes Controller Status Description
No Light Low/No Input Voltage Check the input voltage to the controller. Measure the voltage between
L1 and L2 using an AC Voltmeter. This voltage should be between 196 and
265 VAC.
No light can also be caused by leaving a jumper in the programming position
(covering the two right-most pins just above the DIP switches).
GREEN LIGHT CODES
Flashes Controller Status Description
Constant Standby/Low Voltage Constant Green Light indicates the pump is in Standby mode with the pump
Green stopped. The system is in Standby mode when there is no flow in the system
and the pressure setting has been reached.
It is also possible the system is in a Low Voltage condition when the line
input voltage is between 85-190 VAC.
Blinking Pump Running Flashing Green Light indicates the pump is running.

2 Blinks Dry Well This fault can be caused by:
• Water supply level in well falls below suction inlet of pump.
• Plugged suction screen.
• Restriction in pipe between pump and pressure sensor.
• Air bound pump – see “Purging System”
• Incorrect setting of “MAXIMUM SPEED” switch. Be sure to set the
“MAXIMUM SPEED” switch to 80 Hz when using mismatched pumps
(water ends) and motors.
• Incorrect setting of “MOTOR OVERLOAD SETTING (SFA)” switch.
Ensure the Motor Overload Setting (SFA) Switch is not set higher than the
Service Factor Amps (SFA) listed on the motor nameplate.
• Need for Dry Well Power Calibration. Perform Dry Well Power Calibration
as described in ADVANCED SETTINGS section.
In systems where the motor operates at less than Service Factor Amps the
controller may show a false “dry well” fault. See Dry Well Sensitivity Section.
If problems persists, please verify supply capacity.
The controller will automatically restart according to the chart below.
Dry Well Fault Reset table:
Fault 1 (Start Point) - resets after 1 minute
Fault 2 - resets after 10 minutes
Fault 3 - resets after 20 minutes
Fault 4 - resets after 30 minutes
Fault 5 - resets after 60 minutes and every 60 minutes thereafter
Dry well can be reset by pressing both pushbuttons at the same time
or by turning off the power. A fixed, 1 minute, restart time is also
available. See ADVANCED SETTINGS section.
To clear the fault, turn off
power to the controller, wait
1 minute, turn on power to
the controller. If fault persists
replace controller.
The controller will
automatically restart according
to the table shown on the right.
If fault persists contact installer.
