System


This setting enables system messages transmitted via LPB to be suppressed at the
connected operator unit.


Delivery of the alarm to the OCI can be delayed in the basic unit by setting a delay.
This ensures that unnecessary notifications of a service center resulting from short-time
errors (e.g. temperature limiter cut out, communication error) can be prevented.
It is to be noted, however, that errors occurring for a short period of time, and
reoccurring constantly and rapidly, will also be filtered.

Range of action of changeover

The range of action of central changeover can be defined.
This applies to the following types of limitation:
• Optg mode changeover
• Summer changeover (when selecting ”Central“ on setting line 6621)
Entries:
• Segment: Changeover takes place with all controllers in the same segment.
• System: Changeover takes place with all controllers in the entire system (in all

segments). The controller must be located in segment 0!
