P6
*
Reference variable
[4...20 mA]
SRLO/SRHI
For split-range operation
SRLO
– low range 4 to 11.9 mA
SRHI
– high range 12.1 to 20 mA
P7 *
w/x
[>>] /<>
Direction of action of the reference variable w to the travel/rota-
tional angle x (increasing/increasing or increasing/decreasing).
P8
Gain K
P
30/[50]
On initializing the positioner, the gain is set to the selected value.
If the positioner hunts, the Kp value can be reduced. The positioner
must be then re-initialized afterwards.
P9
*
Pressure limit
ON/[OFF]
The signal pressure can take on the same pressure as the supply air
at the maximum [
OFF
] or, in the case that the maximum actuator
force can damage the valve, the pressure is limited to approx.
2.4 bar.
P10
*
End position w <
[ON]/OFF
Lower tight-closing function:
If w reaches up to 1 % towards the final value that causes the valve
to close, the actuator is immediately completely vented (with
ATO
-
Air to open) or filled with air (with
ATC
- Air to close).
P11
*
End position w >
ON/[OFF]
Upper tight-closing function:
If w reaches up to 99 % towards the final value that causes the valve
to open, the actuator is immediately completely filled with air (with
ATO
- Air to open) or vented (with
ATC
- Air to close).
P14
Info w Initialized
Not initialized
Indicates the internally adjusted set point (adjusted set point in 0 to
100 % according to the settings in P6 and P7).
Press to display external set point (applied set point in 0 to
100 % according to the 4-20 mA signal).
Displays external set point in 0 to 100 % according to the 4-20 mA
signal.
P15
Start
initialization
The initialization process can be interrupted by pressing .
The control valve moves to its fail-safe position
After a power supply failure during initialization, the positioner
starts with the settings from the last initialization (if possible).
P16 *
Start
zero calibration
The zero calibration process can be interrupted by pressing . The
positioner returns to closed-loop operation.
Note: A zero calibration cannot be started when error code E1 ex-
ists.
After a power supply failure during zero calibration, the positioner
starts with the settings from the last zero calibration.
P17
Manual mode Press or to enter set point.
