Direction of action of the reference variable w to the travel/rotational
angle x (increasing/increasing or increasing/decreasing).
On initializing the positioner, the gain is set to the selected value.
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.
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.
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.
Software limit value A1 is displayed or can be changed in relation to
the operating range (steps of 0.5 %).
Software limit value A2 is displayed or can be changed in relation to
the operating range (steps of 0.5 %).
Display only, indicates the reference variable applied in 0 to 100 %
corresponding 4 to 20 mA.
Manual adjustment, refer to section 7.9.
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.
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
original setting.
