Description
Nominal valve travel or opening angle must be entered for nominal
(NOM) or substitute (SUb) initialization.
The possible adjustment range depends on the pin position from the
table for Code 4.
Code 5 is generally locked until Code 4 is set to No, i.e. after a pin
position has been entered, Code 5 can be configured.
Indicates maximum travel/angle reached during initialization after
initialization has been successfully completed.
Select the initialization mode
MAX:
Travel/angle of the closure member from the CLOSED
position to the opposite stop in the actuator.
NOM: Travel/angle of the closure member measured from the
CLOSED position to the indicated OPEN position.
MAN: Manually selected range
SUb:
Substitute calibration (without initialization)
Direction of action of the set point w in relation to the travel/angle x
Automatic adaptation:
AIR TO
On completing initialization, the direction of action
OPEN:
remains increasing/increasing (ää). A globe valve
opens as the set point increases.
AIR TO
On completing initialization, the direction of action
CLOSE:
changes to increasing/decreasing (äæ). A globe valve
closes as the set point increases.
Lower range value for travel/angle in nominal or operating range
The operating range is the actual travel/angle of the valve and is
limited by the lower travel/angle range value (Code 8) and the up-
per travel/angle range value (Code 9).
Usually, the operating range and the nominal range are identical.
The nominal range can be limited to the operating range by the low-
er and upper x-range values. The value is displayed or must be en-
tered.
The characteristic is adapted. See also the example in Code 9.
