defines the alarm setpoint value for the alarm con-
figured under
. Depending on the type of alarm
defined for the parameter
, this can be either an
absolute alarm value or a deviation alarm value (see
also Section on “Alarms”).

,
defines the offset value for manual reset (= operating
point), if
= 0, i.e. the output signal of the controller
is shifted by
.
Notice
This parameter is only required when the controller
does not use any integral component (integral action
time
).
0.0...100 %
,
defines the offset shift for the process variable in the
display (measured value correction).
Example
The display shows 1
°
C less than the actual
temperature. This can be corrected with an input of
+1
°
C.

Changing this parameter has decisive effects on the
