ROUT - RCAS - CAS - Specifies the action taken if the lower control deviation (DV_LO_LIM) is not
AUTO - reached.

Factory default:
MAN - OOS Entry of the disturbance gain for the feedforward control.
Factory default:
2
The disturbance gain is multiplied by the disturbance variable (FF_VAL), the
result is added to the calculated actuating variable.
MAN - OOS Definition of the measurement range (lower and upper limit), the physical unit
and the number of decimal places for the disturbance variable (FF_VAL).
Factory default:
ROUT - RCAS - CAS - Display and entry of the value and status of the disturbance variable.
AUTO -
User input:
MAN - OOS
ROUT - RCAS - CAS - Entry of proportional gain factor. K

MAN - OOS
Factory default:

If the value 0 is specified for this parameter then the status of the parameter
OUT changes to BAD.
ROUT - RCAS - CAS - Releases or restricts the access authorisation of a fieldbus host system on
AUTO - the field device.
MAN - OOS
ROUT - RCAS - CAS - Alarm status display for the upper pre alarm limit value (HI_LIM), including
AUTO - details of the time of the alarm (date, time) and the value that triggered the
MAN - OOS alarm.

In addition the active block alarm can be acknowledged in this parameter
group
Description
= Violation of the limit value for the lower control
deviation is not evaluated.
= No notification if the limit value for the
lower control deviation is violated.
= Reserved for block alarms.
= Violation of the limit value for the lower control
deviation is output with the appropriate priority
(3 = low priority, 7 = high priority) as a user notice.
= Violation of the limit value for the lower control
deviation is output as a critical alarm with the
appropriate priority (8 = low priority, 15 = high priority).
