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
In the event of a recoverable error, the safety output switches to the OFF state and the
protective field status to the “Interrupted” status.
As soon as you have eliminated the cause of the error, the safety output switches back
to the ON state and the protective field status to the “Free” status.
The following errors are classified as recoverable errors:
•
Invalid signal for monitoring case switching
•
No CANopen data were received or the CANopen data received do not meet the
specifications. To enable valid CANopen data to be received again, the NMT status
must be set to operational by the NMT master.
•
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
In the event of a configuration error, the safety output switches to the OFF state and the
protective field status to the “Interrupted” status.
You need to check the configuration in Safety Designer and, if necessary, reconfigure
the device.
Device error
Device errors are serious errors where the safety output switches to the OFF state,
the protective field status to the “Interrupted” status, and the device goes into the
interlocked state.
Once the cause of the error has been rectified, you need to restart the device.
