Description
Note: Codes with marked with an asterisk (*) must be enabled with Code 3 prior to configuration.

Initialization mode (init
mode)
- continued -
MAN2: Manual setting 2 · For all globe valves with unknown
nominal range (OPEN and CLOSED position) · The
positioner determines travel/angle of rotation between
the manually selected OPEN (100 %) and the manually
selected CLOSED position (0 %)
SUB: Substitute calibration · To replace a positioner while the
plant is running, with the least amount of disruption to
the plant
KP: Fine tuning of the input filter · The valve moves through
its entire valve range.
NP: Zero calibration · The zero point is recalibrated.
NOTICE The valve moves briefly from the operating point
to the closed position!

Direction of action of the set point in relation to the valve position
ää
: Increasing/increasing: a globe valve opens as the set
point increases.
äæ
: Increasing/decreasing: a globe valve closes as the set
point increases.
The direction of action is adapted to the change in closed direc-
tion as follows:
ATO: AIR TO OPEN · After initialization, the direction of ac-
tion remains increasing/increasing (
ää
), a globe valve
opens as the mA signal increases.
ATC: AIR TO CLOSE · After initialization, the direction of ac-
tion changes to increasing/decreasing (
äæ
), a globe
valve opens as the mA signal increases.

Lower travel/angle range
value
(lower x-range value)
[0.0] to 80.0 % of the nom-
inal range · ESC
Specified in mm or angle°,
provided Code 4 is acti-
vated.
Lower range value for the travel/angle of rotation in the oper-
ating range.
Nominal range and characteristic are automatically adapted.
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
upper travel/angle 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.
