The categories differ in regards to the method of troubleshooting, and the measures
required to restore the safe multibeam scanner to normal operation.
The safe multibeam scanner creates an entry in the message history for each error.
Recoverable error
For a recoverable error, all safety outputs switch to the OFF state.
As soon as you have eliminated the cause of the error, the safety outputs switch back to
the ON state.
The following errors are classified as recoverable errors:
•
Invalid signal for monitoring case switching
•
Contamination error (front screen)
•
Supply voltage to the safe multibeam scanner too low
•
Ambient light intensity exceeds the ambient light immunity of the safe multibeam
scanner
Configuration error
For a configuration error, all safety outputs switch to the OFF state.
You need to check the configuration in Safety Designer and, if necessary, reconfigure
the device.
Device error
Device errors are serious errors where all safety outputs switch to the OFF state and the
device switches to the locking state.
Once the cause of the error has been rectified, you need to restart the device.
