Drive Fault
Description of Fault
A CATALYST Drive Fault Alarm is generated when the variable frequency drive (VFD) experiences a fault. An alarm will be annunciated following a 5-minute delay (adjustable). The exact nature of the drive fault will be annunciated through the Drive Fault point. During a Drive Fault, the fan will remain non-operational until the drive fault is cleared. The onsite Drive manual may be used as a reference in diagnosing and resolving the fault.
A CATALYST Drive Fault Alarm will automatically reset when the Drive Fault is cleared remotely through the eIQ Platform or locally at the drive.
Possible Causes
A CATALYST Drive Fault is typically caused by:
-
Protective measures to prevent drive or unitary damage.
-
