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:
Flashes Controller Status
No Light Low/No Input Voltage
Flashes Controller Status
Constant Standby/Low Voltage
Green
Blinking Pump Running
Green
Flashes
Controller Status
Controller Action
Constant Controller Error
Red
To clear the fault, turn off
power to the controller, wait
1 minute, turn on power to
the controller. If fault persists
contact installer.
2 Blinks No Water / Loss of Prime
The controller will automati-
cally restart according to the
table shown on the right if
the "DRY RUN RESTART"
switch is set to "CONT."
(Continuous). If the "DRY
RUN RESTART" switch is set
to "5X", the controller will re-
start 5 times. After the 5th No
Water/Loss of Prime Error, the
controller must be manually
reset. If fault persists contact
installer.

Description
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
Description
Constant Green Light indicates the pump is in Standby mode with the pump
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.
Flashing Green Light indicates the pump is running.
RED LIGHT CODES
Description
This information is to be used by professional installers or qualified
personnel only.
Internal controller fault. To clear the fault, turn off power to the controller,
wait 1 minute, turn on power to the controller. If fault persists replace
controller.
This fault can be caused by:
• Water supply level falls below suction inlet of pump.
• Plugged suction.
• Restriction in pipe between pump and pressure sensor.
• Air bound pump – see "Purging System"
• 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 No Water/Loss of Prime Power Calibration. Perform No Water/
Loss of Prime 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 "No Water/Loss of Prime" fault. See Advanced
Settings 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
No Water/Loss of Prime 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.
