Troubleshooting
Refer to previous “Attention” statements before performing service or
troubleshooting.
If trouble is experienced in the operation of the motor, assure that:
•
The bearings are in good condition and operating properly.
•
There is no mechanical obstruction to prevent rotation in the
motor or in the driven load.
•
The air gap is uniform. (Consult manufacturer for specifications).
•
All bolts and nuts are tightened securely.
•
Proper connection to drive machine or load has been made.
In checking for electrical trouble, assure that:
