Function
for single or double acting actuators, air is vented from actuator or actuator is blocked in
case of an electrical power failure
Shut-off function
If the setpoint goes below the set value, the positioner immediately moves the actuator to
the closing position. Range: 0...20% of positioning signal.
Travel
Angle of rotation
Used range 25...120 ° (rotary actuators
optionally 270°)
25...60 ° (linear actuators)
Stroke time
Range 0...200 seconds, individually configurable for each
direction
Dead band time limit
Range 0...200 seconds (monitoring parameter for control until the deviation is within the tol-
erance band)
Stroke limiting
Min. and max. limits,
freely configurable within 0...100% of total travel (> 20 %)
Air supply
Instrument air
free of oil, water and dust to DIN/ISO 8573-1
pollution and oil contents according to Class 3

Caution: Do not exceed the max. operating pressure of the actuator!
Air consumption
< 0.03 kg/h (0.08 scfm) (independent of supply pressure)
