(g). 1 - Angle of rotation limiting - Not possible
2 - Releasing the adapter - Not possible
(h). Adjusting control signals
The actuators are controlled by a 0...10 VDC or 0...20 mA
signal. The motor stops running when the damper end-stop or
actuator end-stop is reached. For manual operation of the
damper the gearing is disengaged by means of the self-
resetting button (See Figure 2 e.).
WARNING: When calculating the torque required
to operate dampers, it is essential to take info
account all the data supplied by the damper
manufacturer.

Installation and adjustment

Figure 3: Mounting Instructions
Installation
Attach the actuator to the damper spindle by means of the
adapter and secure the locking device with the screws
provided.
Selecting the direction of rotation
• In order to reverse the direction of rotation (CW/CCW),
loosen screw (See Figure 1 a.) and remove the cover.
• The direction of rotation can be changed by switching
microswitch c (See Figure 2c).
• Factory setting: Clockwise (CW) rotation.
Control Signal Adapting
By switching microswitch d1 to ON position, the control signal
Y1 or Y2 will be adapted to the chosen angle of rotation (See
figure 2d).
Setting Span and OFFSET
The potentiometers O and S help to match control signals Y1
and Y2 to any make of controller (see figure 5).

Wiring
WARNING:
• The electrical connections for the actuators must
be executed in accordance with the relevant legal
requirements.
• In order to avoid any personal injury or damage
to the equipment or other property, always
isolate the power supply before commencing
any work on the electrical wiring.
• In order to avoid danger to property, it is important
for the equipment to be used solely for which it is
intended.
WARNING: The integrated circuits in the actuator
are sensitive to static electricity. Take suitable
precautions.

Electrical connections via safety isolating
transformer
• In order to make the electrical connections, loosen screw
(Fig. 1 a.) and remove the cover.
• Actuator wiring diagram: according to terminal connection
(Fig. 4).
• Parallel connection: according to terminal connection (Fig. 6).
• Auxiliary switches: according to terminal connection (Fig. 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.
