Fault Description.
This information is to be used by professional installers or qualifi ed
personnel only.
This fault can be caused by:
• High ambient temperature. The maximum ambient temperature rating
is 122ºF (50ºC).
• Low ambient temperature. The minimum ambient temperature rating
is 0ºF (-18ºC).
Check for a fan failure. The fan will turn on when the temperature inside
the controller reaches 140ºF (60ºC). The fan will also 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 fi lter 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 1 minute. Remove the three motor
wires from the terminal block. Using an ohmmeter, measure the
resistance from phase to phase. A disconnected or broken wire will be
indicated by a high resistance reading (20 ohms or higher).
