Check the input voltage to the controller. Measure the input voltage be-
tween phases using an AC Voltmeter. This voltage should be greater than
140Vac for the status indicator light to turn on.
GREEN LIGHT CODES
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).
Flashing Green Light indicates the pump is running.
ORANGE LIGHT CODES
Constant Orange Light indicates the system input voltage is low. For 230V
units, the orange light will be indicated when the input voltage is between
140Vac and 170Vac. For 460V units, the orange light will be displayed
when the input voltage is between 140Vac and 310Vac.
Blinking Orange Light indicates the No Water/Loss of Prime Fault is dis-
abled and the pump/motor is running. For details see 2 Blinks under Red
Light Codes.
RED LIGHT CODES
Internal controller fault. The controller may be internally damaged. Verify
the error by turning power off, waiting 5 minutes then apply power. If the
error persists, replace controller.
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.
• Deadheaded pump, pump running against a closed valve.
• Filling long irrigation lines on start-up**
• Incorrect setting of Motor Overload Setting switches.
In systems where the motor operates at less than Service Factor Amps
the controller may show a false No Water/Loss of Prime fault. Reduc-
ing the motor overload setting will eliminate the false readings.
If problem persists, please verify supply capacity.
The controller will automatically restart according to the No Water Restart
Time switches.
** Controllers with software revision A3 or later allow the user to disable
this function by holding down both push buttons for 5 seconds while the
pump/motor is running. While the no water/loss of prime function is dis-
abled, the status LED will blink orange while the pump/motor is running.
To re-enable the function, hold down both push buttons for 5 seconds
while fault is disabled and the pump/motor is running.
It is not recommended to keep the No Water/Loss of Prime fault disabled
after the system has been primed. Doing so can result in damage to the
pump.
