4 DMS1.1 / DM1.1 / DML1.1 Proportional Actuators
Electrical connections via safety isolating transformer
• In order to make the electrical connections, loosen screw (Figure 1 a.)
and remove the cover.
• Actuator wiring diagram according to terminal connection (Figure 4).
• Parallel connection according to terminal connection (Figure 6).
• Auxiliary switches according to terminal connection (Figure 7).
• Feedback potentiometer not possible.
• The electrical installation work should be carried out by a qualified
electrician.
• Wrong connections can damage the equipment. Check the connections
before energizing the power supply.
• Local accident prevention regulations should always be adhered to when
installing the actuators.
• The actuator moves about slightly while it is working so it is important to
use flexible leads for the electrical connections.
Auxiliary switches adjustment (See Figure 2 a. - b.)
Example:
Switching position adjustment a. to 30° and b. to 70°.
30°: Depress the manual button (Figure 2 e.) and rotate the adapter (Figure 2 f.)
to the 30° position. Slightly loosen the Phillips screw in the cam wheel a. so
that the wheel can be moved by hand. Rotate the cam wheel a.
counterclockwise until the switch button can be seen. Then tighten-back
the Phillips screw in the cam wheel a..
70°: Rotate the adapter (Figure 2 f.) in the same manner as before to the
70° position. Slightly loosen the Phillips screw in the cam wheel b. so that
the wheel can be moved by hand. Rotate the cam wheel b. clockwise until
the switch button can be seen. Then tighten-back the Phillips screw in the
cam wheel b..
Factory setting of auxiliary switches
The two auxiliary switches a. and b. are factory set at the to approximately
10° CW (a.) and 80° CW (b.).
