Function
for single or double acting actuators,
air is vented from actuator or actuator is blocked if input signal < 3.9 mA
Shut-off point
Setable to 0...20 % of signal
(when the value falls below the set value, the positioner immediately sets the valve to the
closed position)
Travel
Angle of rotation
60 ° nominal range for attachment to linear actuators in acc. with DIN/IEC 534
120 ° nominal range for attachment to rotary actuators in acc. with VDI/VDE 3845
Used range is 25...100 % of nominal range
Adjusted speed
Can be adjusted separately for each direction as a 0...200 second ramp
Time-out monitoring
Range 0...200 sec
(monitoring parameter for control until the deviation reaches the tolerance band)
Travel limit
Min. and max. limits, freely configurable within 0...100 % of total travel
