Safety notes
• The device contains electrical and electronic components and is not allowed to be
disposed of as household refuse. All locally valid regulations and requirements must
be observed.
Product features
Mode of operation
The actuator is connected with a standard modulating signal of DC 2...10 V and travels
to the position defined by the positioning signal. Measuring voltage U serves for the
electrical display of the valve position 0...100% and as slave control signal for other
actuators.
Direct mounting
Simple direct mounting on the ball valve with only one screw. The mounting orientation
in relation to the ball valve can be selected in 90° steps.
Manual override
Manual override with magnet possible (gear disengagement as long as the magnet
adheres to the magnet symbol). The Z-MA magnet for the gear disengagement is
enclosed.
High functional reliability
Adjustable angle of rotation
The actuator is overload protected, requires no limit switches in intermediate positions
and automatically stops when the end stop is reached (at rest).
The rotary actuator can be adjusted beginning with 90° (A – AB = 100%) in 2.5°
increments. The scale corresponds to 25...100% of the kvs value.

Notes
!
• Connection via safety isolating transformer.
• Parallel connection of other actuators possible. Observe the performance data.
