MAX: Maximum range of the control valve, the travel/angle of
the closure member from the CLOSED position to the
opposite stop in the actuator.
NOM: Nominal range of the control valve, the travel/angle of
the closure member measured from the CLOSED position
to the indicated OPEN position.
MAN: Manual adjustment: upper x-range value
SUb: No self-adjustment (emergency mode)
ZP: Zero calibration
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:
On completion of initialization, the direction of action remains in-
creasing/increasing (ää), a globe valve opens as the mA signal
increases.
AIR TO CLOSE:
On completion of 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 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 set lower limit and 100 % to the set upper limit.
