P7
w/x
>> /<> [>>]
Direction of action of the reference variable w to the travel/rotational
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.
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
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).
This action always lead to maximum tight-closing of the valve.
P11
End position w >
ON/ [OFF]
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).
This action always lead to the valve being completely opened.
P12
Switching point A1
0 to 100 % [2 %]
Software limit value A1 is displayed or can be changed in relation to
the operating range (steps of 0.5 %).
P13
Switching point A2
0 to 100 % [98 %]
Software limit value A2 is displayed or can be changed in relation to
the operating range (steps of 0.5 %).
P14
Info w Display only, indicates the reference variable applied in 0 to 100 %
corresponding 4 to 20 mA.
P15
Start
initialization
The initialization process can be interrupted by pressing the rotary
pushbutton. The control valve moves to its fail-safe position.
Over parameter code
P0 , the fail-safe position can be canceled
again and the positioner then starts with the original setting.
Also after a power supply failure, the positioner starts with its orig
-
inal setting.
P16
Start
zero calibration
The zero calibration process can be interrupted by pressing the ro
-
tary pushbutton. The control valve moves to its fail-safe position.
Over parameter code
P0 , the fail-safe position can be canceled
again and the positioner then starts with the original setting.
Also after a power supply failure, the positioner starts with its orig
