8-2 Error Diagnosis and Troubleshooting
Publication 825-UM001B-EN-P January 2001
Cause of the warning may be:
•
Unbalanced mains
•
Defective motor winding
•
Defective contacts
Actions
If the installation can be shut down without loss of production or without affecting safety:
•
Switch off the installation
•
Search for the fault and repair it
If it is important to keep the operation running:
•
Continuously monitor the level of ACTUAL VALUES ASYM…%
•
If the alarm level continues to rise, measures should be taken so that the installation
can be shut down quickly.
•
If the alarm level remains steady in the region of the set alarm threshold, it is
permissible to wait until the next planned interruption in operation to locate and
repair the fault.

EXAMPLE
Asymmetry
Faults in the motor or the installation can develop and lead to the set threshold being rapidly
exceeded. When this occurs and the related threshold is reached, the following responses
occur:
•
LED lights
•
LCD:
•
The assigned output relay picks up
ATTENTION
!
While the alarm is on (red LED flashing), the alarm function cannot
be disabled (refer to page
).
