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
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 s witch
DE-S2
,
– If required, switch the motor supply jumpers
on the clamps 2 and 3.

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!
