Bus power supply enables the bus system to be powered directly by the individual
controllers (no central bus power supply). The type of bus power supply can be
selected.
Off
No bus power supply via the controller.
Automatic
The bus power supply (LPB) via the controller is automatically switched on and off
depending on the power requirements of the LPB.
The display shows whether the controller currently supplies power to the bus:
Off
Bus power supply via the controller is currently inactive
On
The bus power supply via controller is currently active. At the moment, the
controller supplies some of the power required by the bus.

6610 Display system messages
6612 Alarm delay
This setting enables system messages transmitted via LPB to be suppressed at
the connected operator unit.
Delivery of an alarm to the OCI and alarm relay can be delayed in the basic unit by
setting a delay.
This ensures that unnecessary notifications to a service center resulting from short-
time errors (e.g. temperature limiter cut out, communication error) can be
suppressed.
It is to be noted, however, that errors occurring for a short period of time, and
reoccurring constantly and rapidly, will also be filtered.
