WARNINGS CAREFULLY BEFORE INSTALLING AND
SAVE IT FOR FUTURE USE
General Features
The actuators are intended for the operation of various kind of
mixing valves, throttle dampers and ballvalves.

The actuator allows ON/OFF and Floating control use,
operating via contacts.
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 pushbutton (
See Figure 2 d. ).
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
(See Figure 3).
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 reversed with the plug
(See Figure 2 c.) .
• Factory setting: Clockwise (CW) rotation .

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
(Fig. 4) .
• Parallel connection: not possible
• Auxiliary switches: according to terminal connection (Fig. 5) .
• 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.
• When using multi-stranded wire apply a cable ferrule to the
cable end.
Auxiliary switches adjustment (See Figure 2 a. - b.)
Example:
Switching position adjustment
a. to 30° and b. to 70°.
30° : Depress the latch pin (Figure 2 d.) and rotate the adapter
(Figure 2 e.) to the 30° position. Slightly loosen the Phillips
screw in cam wheel a. so that the wheel can be moved by
hand. Rotate the cam wheel a. counterclockwise until the
cam of the microswitch can be seen.
Then tighten-back the Phillips screw in the cam wheel
a. .
70° : Rotate the adapter (Figure 2 e.) 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 cam of the
microswitch 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. ).
WARNING: When calculating the torque required
to operate dampers, it is essential to take info
account all the data supplied by the damper
manufacturer.
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.
