DV_LO_LIM ROUT - RCAS -
CAS - AUTO -
MAN - OOS
Entry of the limit value for the lower control deviation. If the
controlled variable undershoots the setpoint value by this value,
then the warning DV_LO_ALM is output.
User input:
Range and unit of PV_SCALE
Factory setting:
-3402823466 x 10
38
Note!
If the setting for the end of the scale is changed in the PV_SCALE
parameter this value should be modified accordingly.
DV_LO_PRI ROUT - RCAS -
CAS - AUTO -
MAN - OOS
Specifies the action taken when the lower control deviation
(DV_LO_LIM) is undershot.
User input:
0
The violation of the limit value for the lower control deviation is not
evaluated.
1
No notification if the limit value for the lower control deviation is
violated.
2
Reserved for block alarms.
3-7
The violation of the limit value for the lower control deviation is
output as a user notice with the appropriate priority (3 = low
priority, 7 = high priority).
8-15
The 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).
Factory setting:
0
FF_GAIN MAN - OOS Entry of the disturbance gain for the feedforward control.
Factory setting:
0
Note!
The disturbance gain is multiplied by the disturbance variable
(FF_VAL) and the result is added to the calculated manipulated
variable.
FF_SCALE MAN - OOS Definition of the measuring range (lower and upper limit), the
physical unit and the number of decimal places for the
disturbance variable (FF_VAL).
Factory setting:
0...100%
