Description
Note: Codes with marked with an asterisk (*) must be enabled with Code 3 prior to configuration.
7*
Direction of action w/x
[ää]
äæ
ESC
Direction of action of the reference variable w in relation to the
travel/angle of rotation x (increasing/increasing or in
-
creasing/decreasing).
Automatic adaptation:
AIR TO OPEN: After initialization, the direction of action remains
increasing/increasing (ää), a globe valve opens as the
reference variable increases.
AIR TO CLOSE: After initialization, the direction of action
changes to increasing/decreasing (äæ), a globe valve
closes as the reference variable increases.
8*
Travel/angle range start
(lower x-range value)
0.0 to 80.0 [0.0] % of the
nominal range
Specified in mm or angle ° provided
Code 4 is set
ESC
Starting value for the travel/angle of rotation in the nominal or
operating range.
The operating range is the actual travel/angle of the control
valve and is limited by the travel/angle range start (Code 8) and
the travel/angle range end (Code 9).
Usually, the operating range and the nominal range are iden-
tical. The nominal range can be limited to the operating range
by the travel/angle range start and end. Value is displayed or
must be entered.
The characteristic is adapted.
See also the example in Code 9.
9*
Travel/angle range end
(upper x-range value)
20.0 to 100.0 [100.0] % of
the nominal range
Specified in mm or angle ° provided
Code 4 is set
ESC
End value for the travel/angle of rotation in the nominal or oper
-
ating range. Value is displayed or must be entered.
The characteristic is adapted.
Example: The operating range is modified, for example, to limit
the range of a control valve which has been sized too large. For
this function, the entire resolution range of the reference variable
is converted to the new limits. 0 % on the display corresponds to
the adjusted lower limit and 100 % to the adjusted upper limit.
10*
Travel/angle lower limit
(lower x-limit)
[No]
0.0 to 49.9 % of the
operating range
ESC
Limitation of the travel/angle of rotation downwards to the en
-
tered value.
The characteristic is not adapted.
See also example in Code 11.
