8 Troubleshooting and fault elimination

You can recognize immediately whether a fault has occured by
display elements or status information (chapter 8.1).

The faults can be analysed by using the history buffer (chapter 8.2)
and the list in chapter 8.3. This list helps you to eliminate the faults.

8.1 Troubleshooting

8.1.1

Display at the controller

During operation without operating module two LED at the unit
front indicate the operating status.
