Safety notes

The damper actuator is not allowed to be used outside the specified field of applica tion,

especially in aircraft or any other form of air transport.

• Assembly must be carried out by trained personnel. Any legal regulations or regulations

issued by authorities must be observed during assembly.

• The device may only be opened at the manufacturer‘s site. It does not contain any parts

that can be replaced or repaired by the user.

• The cable must not be removed from the device.

• When calculating the required torque, the specifications supplied by the damper

manufacturers (cross section, design, installation site), and the air flow conditions must

be observed.

• The device contains electrical and electronic components and is not allowed to be disposed

of as household refuse. All locally valid regulations and requirements must be observed.

Modulating damper actuator AC/DC 24 V, 20 Nm

Product features

Mode of operation The actuator is controlled by means of a standard control signal DC 0 ... 10 V. It opens to the

position dictated by this signal. The measuring voltage U allows the damper position (0 ... 100%)

to be electrically indicated and serves as a follow-up control signal for other actuators.

Simple direct mounting Simple direct mounting on the damper spindle with a universal spindle clamp, supplied with

an anti-rotation strap to prevent the actuator from rotating.

Manual override Manual operation is possible with the self-resetting pushbutton (the gearing latch remains

disengaged as long as the pushbutton is pressed).

Adjustable angle of rotation Adjustable angle of rotation with mechanical end stops.

High functional reliability The actuator is overload-proof, requires no limit switches and automatically stops when the

end stop is reached.

media of heating, cooling and airconditioning

systems (e.g. in fresh air/

exhaust air ducts). Designed for locking on control and display systems.

Additionally, the device can be supplied with a passive temperature sensor

e.g. PT100, PT1000, NTC10k etc.

Mounting Advice

The sensor is directly mounted to the ventilation duct by means of a

mounting flange or by screws.

Please also note our general remarks in our INFOBLATT THK.

Electrical connection

The devices are constructed for the operation of protective low voltage

(SELV). For the electrical connection, the technical data of the

corresponding device are valid. Specially with regard to passive sensors

(e.g. PT100 etc.) in 2wire

conductor versions, the wire resistance of the

supply wire has to be considered. Probably, the same has to be

compensated by the following electronics. Due to the selfheating,

the wire

current affects the accuracy of the measurement. Thus, the same should

not exceed 1mA.

Application Notice

Due to air circulations dirt and dust particles can be piled up in the

course of time on the sintered filter which is protecting the sensor.

Thus, the function of the sensor can be affected. After having

dismantled the filter, the same can be cleaned by blowing it out with oilfree

and filtered compressed air, superclean

air or nitrogen or by

washing it out with distilled water. If the filter is too dirty, the same

should be replaced.

Refrain from touching the sensitive humidity sensor. Any touch of the

same will result in an expiration of the warranty.

When using the sensor in aggressive gases, an early recalibration or a

change of the humidity sensor can become necessarily. Such a

recalibration or a probable sensor change do not come under the

general warranty.
