12.1 Preparations for troubleshooting

Supply lines of linked system components can be closed for maintenance pur-
poses. These must be reopened after the device is put back into service.

NOTE

Event list:

The software keeps an event list with up to 1000 events in chronological order
(specification of date). The event list provides information about incorrect be-
havior, refer to 9.6.3.

The export of event data to a special data carrier (memory stick) is possible after
consultation with Service. The exported data can be sent to the manufacturer for
fault analysis, refer to CSV Export, 9.6.1.

Events are: Start, Stop, Ignition, Insufficient cooling air, Calibration
