End Stop Behav.
Menu / parameter Value range Description
Device Setup / End Stop Behav.
Tight Shut 0% 0 to 45.0 The shut-off value is a percentage of the working range from which the 0 % position is approached.
Once the specified position limit value is reached, the actuator moves into the 0% end position.
Control at 0% On, Off Use this parameter to set the end position behavior. If the parameter is activated, the 0 % position is
controlled. Otherwise, the actuator moves into the 0 % mechanical end position.
Dead Angle 0% 0.0 to 45.0 % Use this parameter to cut off the unusable range of the valve flow characteristic curve from the point of
view of control.
The dead angle is a percentage of the working range to which the valve is moved if the input signal is
4.16 mA.
Note
If the parameter is changed, the switching points of the binary feedback opposite the valve area which
had possibly been previously adjusted will shift.
Tight Shut 100% 55.0 to 100 The shut-off value is a percentage of the working range from which the 100 % position is approached.
Once the specified position limit value is reached, the actuator moves into the 100 % end position.
Control at 100% On, Off Use this parameter to set the end position behavior. If the parameter is activated, the 100% position is
controlled. Otherwise, the actuator moves into the 100% mechanical end position.
Dead Angle 100% 55.0 to 100.0 % Use this parameter to cut off the unusable range of the valve flow characteristic curve from the point of
view of control.
The dead angle is a percentage of the working range to which the valve is moved if the input signal is
19.84 mA.
Note
If the parameter is changed, the switching points of the binary feedback opposite the valve area which
had possibly been previously adjusted will shift.
