Tight Shut 0% 0 to 45.0
Control at 0% On, Off
Dead Angle 0% 0.0 to 45.0 %
Tight Shut 100% 55.0 to 100
Control at 100% On, Off
Dead Angle 100% 55.0 to 100.0 %
Description
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.
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.
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.
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.
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.
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.
