Connection examples
Connection example 1 (three-way valve)
• Operation with single-phase alternating current (three-step control)
• Final switch-off via switch DE-S1 (limitation in closing direction "CLOSED") and DE-S2 (limit-
ation in opening direction "OPEN"), load-dependent
NOTE!
If you want to operate the actuator with only two torque switches DE-S1 and DE-S2, the associ-
ated valve must be designed to accept the forces of the actuator.
Refer to the documentation for the valve. If required, contact your manufacturer!
Connecting the actuator
– Connect the grounding conductor of the
connecting line (green/yellow wire) to the
grounding conductor clamp
– N of connecting line to clamp 1.
– Control line extending actuator stem
"CLOSED" to clamp 11.
– Control line retracting actuator stem
"OPEN" to clamp 14.
– Insert jumpers; from clamp 10 to clamp 3
and from clamp 13 to clamp 2.

Testing the actuator
– Use a three-step controller to control the actuator.
– Use an isolated screw driver to operate the
switching rolls of the switch and check
whether the switch actually does deactivate
the motor:
With extending actuator stem ->
upper switch DE-S1 ,
With retracting actuator stem ->
lower switch DE-S2 ,
– If required, switch the motor supply jumpers
on the clamps 2 and 3.
