Description
WARNING
This fault can be caused by:
• Electrical failure of the motor
• Electrical failure of wiring between controller and motor.
• Miswiring of motor cable.
Verify the error by turning power to controller off for 1 minute and then on.
If error persists, motor and wiring between controller and motor must be
checked. Turn power off and wait 5 minutes. See Section 5 Insulation
and Winding Resistance Tests for details.
This fault can be caused by:
• High ambient temperature. The maximum ambient temperature
rating is 122º F (50º C).
• Low ambient temperature. The minimum ambient temperature
rating is -4º F (-20º C).
Check for a fan failure. The fan will turn on when the temperature
inside the controller reaches 140º F (60º C). The fan will turn on for
1 second each time the controller starts the motor. If the fan never
turns on, check fan connections and replace as needed. Ensure that
the external fan intake filter is not blocked or clogged. It can be
removed for cleaning and replacements are available.
This fault can be caused by:
• Disconnected or broken wire between the controller and motor.
Verify the error by turning power to controller off for 1 minute and
then on. If error persists, motor and wiring between controller and
motor must be checked. Turn power off for 5 minutes. See Section 5
Insulation and Winding Resistance Tests for details.
This fault can be caused by:
• Pressure 20 PSI below set point for 30 seconds. May be a broken
pipe or tripped pressure relief valve. If 20 PSI or more pressure
drop for 30 seconds is normal for the system, switch the low pressure
cut-off protection off or change system to prevent the pressure drop.
