This manual is also suitable for

64-TW-DF

D+H KA 34 is a chain drive designed for controlling turning sash windows. It features a force and positioning control system to ensure evenly and reliable opening and closing. The drive's dual chain design distributes force evenly across the window sash, making it suitable for wide windows. It supports integration with smoke vent systems and daily ventilation systems, thanks to its compatibility with D+H smoke and heat vent control panels.

Application

Chain drive KA-TW-DF is a special type of chain drive KA 32-BSY, with which two drives are

combined in one tube for doubling the force. The force is evenly distributed on the window

wing by this special structural shape, which leads to trouble-free closing, especially in case

of particularly wide wings. The drive has a force/ and positioning control. This control will

ensure, that the drive will OPEN and CLOSE evenly and reliable. In case of failure of one part

of the drives, e.g. by parting of a cable or overload, the other part of the drives will be

automatically switched off. Turning sash windows can be electrically remote controlled with

this drive. The drive is suited for using in smoke vent systems as well as for daily ventilation.

D+H offers a wide range of smoke and heat vent/ and ventilation control panels for triggering.

Guarantee

You will get 2 years guarantee for all D+H products from date of verified handing over of the

system up to maximal 3 years after date of delivery, if mounting and starting has been carried

out by a D+H authorized distributor.

D+H guarantee is expired, in case of connection of D+H components on external systems or

mixing of D+H products with parts of other manufacturers.

! IMPORTANT ! Safety Notes

1.We recommend, that mounting of the drive is carried out by a D+H-distributor, whose

qualification and experience is ensured by regular in-house training.

2.Inspection and maintenance has to be carried out according to D+H-maintenance

instructions.

Repair of the drive unit is to be carried out exclusively by D+H.

D+H-warranty and functioning guarantee is only valid in case of operation on D+H -

smoke vent/ and ventilation control panels according to current regulations, which must

be observed.

3.Observe maximum pressure load of chain (see page 3)!

4.Only suited for inside mounting. Use always rain detectors, if danger of rain.

5.Observe enclosed red safety slip!

6. Danger of violent pressure within reach!

Attention!

Both the „Soft Close“ potentiometers must be turned in

same position on both sides of the drives.

Adjusting of Locking Pressure (soft-close)

(only KA 64-TW-DF)

Locking pressure will be reduced 20mm before the chain is completely retracted, so that possible

different wing projections must not be compensated. Locking pressure can be infinitely increased

up to approx. 2x 250N, if factory-set locking pressure of approx. 2x 130N should not be sufficient.

1.Pull out blind rivet. Stick in screw driver

and turn to the right to increase locking

pressure.

2.Put blind rivet in again after adjustment.
