Automatic adaptation:
AIR TO OPEN:
On completing initialization, the direction of action remains in-
creasing/increasing (ää), a globe valve opens as the mA signal
increases.
AIR TO CLOSE:
On completing initialization, the direction of action changes to
increasing/decreasing (äæ), a globe valve closes as the mA
signal increases.
Lower range 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 lower x-range value (Code 8) and the
upper x-range value (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 lower and upper x-range values.
Value is displayed or must be entered.
The characteristic is adapted. See also the example in Code 9!
Upper range value for the travel/angle of rotation in the nominal
or operating 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.
Limitation of the travel/angle of rotation downwards to the en-
tered value, the characteristic is not adapted.
The characteristic is not adapted to the reduced range. See also
example in Code 11.
