10.4.3.2 Errors
When an Error or Alarm occurs, always check the controller log messages. The log mes-
sages will provide more details about the failure and the history of events leading up to the fail-
ure. From the log messages, you can determine the specifics about the cause of the failure to
correct the underlying problem.
Eliminate errors and faults in compliance with work safety rules. Troubleshooting only by
qualified and trained staff.
More information about error and alarm messages, causes, remedy and clearing errors can
be found in the WorkBench online help and in KDN.
