values [default setting]
Description
9* Travel/angle range end
(upper x-range value)
20.0 to [100.0 %] of the
nominal range, ESC
Note:
Specified in mm or
angle ° provided Code 4 is
activated.
Upper range value for travel/angle in nominal or operating range
The 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 set point 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)
0.0 to 49.9 % of the oper-
ating range, [No], ESC
Limits travel/opening angle to the entered value (lower limit). The
characteristic is not adapted.
The characteristic is not adapted to the reduced range. See also ex-
ample in Code 11.
11* Travel/angle upper limit
(upper x-limit)
50.0 to 120.0 %, [100 %]
of the operating range,
No, ESC
Limits travel/angle to the entered value (upper limit). The characteris-
tic is not adapted.
Example:
In some applications, it is better to limit the valve travel,
e.g. if a certain minimum medium flow is required or a maximum
flow must not be reached.
The lower limit must be adjusted with Code 10 and the upper limit
with Code 11.
If a tight-closing function has been set up, it has priority over the
travel limitation.
When set to No, the valve can be opened past the nominal travel
with a set point outside of the 0 to 100 % range.
14* Reference variable range
start (w-start)
0.0 to 49.9 %, [1.0 %] of
the span adjusted in
Code 12/13, No, ESC
If the set point w reaches up to the entered percentage at the final
value that causes the valve to close, the actuator is immediately com-
pletely vented (with AIR TO OPEN) or filled with air (with AIR TO
CLOSE). This action always lead to maximum tight-closing of the
valve.
Codes 14/15 have priority over Codes 8/9/10/11.
Codes 21/22 have priority over Codes 14/15.
