READ THIS INSTRUCTION SHEET AND THE SAFETY WARNINGS CAREFULLY BEFORE INSTALLING
AND SAVE IT FOR FUTURE USE
GENERAL FEATURES
The actuators are intended for the operation of air dampers
in HVAC systems. The universal adapter allows them to
be mounted directly on the damper spindle where they are
secured with the locking device supplied.
MODE OF OPERATION
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.
INSTALLATION AND ADJUSTMENT
Installation
Attach the actuator to the damper spindle by means of
the adapter and secure the locking device with the screws
provided.
Angle of rotation limiting
An angle-of-rotation/working range of less than 90° can
be limited mechanically by repositioning the adapter in
5° steps as required. The adapter is released by simply
pressing the adapter clips on the lower side of the actuator.
Selecting the direction of rotation
• In order to reverse the direction of rotation (CW/CCW),
loosen screw and remove the cover.
• The direction of rotation can be changed by switching
microswitch c.
• 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.
Setting Span and OFFSET
The potentiometers O and S help to match control signals
Y1 and Y2 to any make of controller.
WARNING:
When calculating the torque required to operate dampers, it is essential to take info account all the data supplied
by the damper manufacturer.
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.
The integrated circuits in the actuator are sensitive to static electricity. Take suitable precautions.
WIRING
Electrical connections via safety isolating
transformer
• In order to make the electrical connections, loosen screw
and remove the cover.
• Actuator wiring diagram: according to terminal
connection.
• Parallel connection: according to terminal connection.
• Auxiliary switches: according to terminal connection.
• 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
Example: Switching position adjustment a. to 30° and b.
to 70°.
30°: Depress the manual button and rotate the adapter 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 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.
