ROUT - RCAS - CAS - Entry of the limit value for the upper control deviation.
AUTO - If the controlled variable exceeds the setpoint value by this value, then the
MAN - OOS warning DV_HI_ALM is output.
User input:
Factory default:
2
If the setting for the end of the scale is changed in the parameter PV_SCALE
this value should be modified accordingly.
ROUT - RCAS - CAS - Specifies the action taken when the upper control deviation (DV_HI_LIM) is
AUTO - exceeded.

Factory default:
ROUT - RCAS - CAS - Alarm status display for the lower control deviation, including details of the
AUTO - time of the alarm (date, time) and the value that triggered the alarm.
MAN - OOS The controlled variable is below the setpoint value by more than the value
specified in the parameter DV_LO_LIM.

In addition the active block alarm can be acknowledged in this parameter
group.

Description
Range and engineering units of PV_SCALE
+ INF
Note!
= Violation of the limit value for the upper control
deviation is not evaluated.
= No notification if the limit value for the
upper control deviation is infringed.
= Reserved for block alarms.
= Violation of the limit value for the upper 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 upper control
deviation is output as a critical alarm with the
appropriate priority (8 = low priority, 15 = high priority).
