For initialization using NOM or SUb, the nominal travel/angle of
rotation of the valve must be entered.
The permissible adjustment range depends on the pin position
according to the table for Code 4.
After initialization has been successfully completed, the maximum
nominal travel/angle reached on initialization is displayed.
Select the initialization mode
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!
