Troubleshooting
Fan Belt/Motor Adjustment Fault
Description of Fault
A CATALYST Fan Belt/Motor Adjustment Fault is an indication of power spikes within the CATALYST variable frequency drive. It is typically caused by abnormal mechanical operation of the unit’s fan. A normal operating fan assembly should have all components rotating smoothly without oscillation or vibration, and therefore should not cause power spikes.
A CATALYST Fan Belt/Motor Adjustment Fault will automatically reset if the drive goes an entire 24-hour period without seeing a power spike.
Possible Cause
A CATALYST Fan Belt/Motor Adjustment Fault is typically caused by:
-
Worn, loose, or improperly adjusted belt.
-
Belt alignment issue.
-
Improperly adjusted sheave.
-
Loose or broken motor mount causing the motor to shake.
-
Worn bearings.
