(please also refer to the Installation Instructions supplied with

the DEWERT control units).

Please bear in mind that installing mechanical

limit stops into your end product considerably

increases the safety standard.

In conjunction with the (), it is

absolutely imperative that mechanical limit stops are installed in your

end product at the , in order

to prevent mechanical damage to the drive system.

Attention!

The version of the drive system with loose nut seat a fixed

mechanical stop in the end product in order to prevent the stroke tube from being

pulledout. This could otherwise damage the drive system.

MEGAMAT 2requires

For technical reasons or to save costs, mechanical limit stops are not always provided.

In safety-critical drives we therefore recommend using an additional safety limit switch

which in the event of a defective top limit switch protects against dangerous excess

travel and failure. The safety limit switch puts the drive permanently out of action as

soon as any overshooting of the regular limit switch takes place. The safety limit switch

is integrated directly into the drive and does not require any additional fitting. However

this can increase the fitting dimension of the drive by 23 mm.

Caution!

Only ever connect or disconnect electrical components when they are voltage-free.

Installation errors - e.g. as a result of tolerances in the fitting - can have a considerable effect

on the disengagement forces of the GQR. Incorrect installation can bringt about a significant

increase in the disengagement forces, thereby causing them to considerably exceed the

specification.

is not the case, additional lateral forces act on the drive unit. A significant increase in the

withdrawal forces can occur as a result of the fittings being misaligned by 1° and more. A

fitting position of almost 0° is ideal.

Recommended arrangement of the fittings

Recommendation

Besides precise alignment of the fittings, we recommend using only one fixing bracket at

either side of the fittings. This measure reduces the risk of a misalignment of the two fixing

brackets which would cause the drive unit to tilt. Fittings with two fixing brackets can be

used, but these must be precisely aligned to ensure that the withdrawal force does not

increase.

Fix the bracket on the one side to utilize the elongated hole. This permits any possible diffe-

rences in length between the fitting dimension of the drive and your application to be appro-

priately adjusted. : the elongated hole (c) should offer at least 2mm play.

5.Operation

For drawing up the Operating Instructions for the end product, you can use the specialist

information described herein. Please bear in mind that these instructions are intended for

you as a specialist and not for the possibly non-technically trained operator of the end

product.

units.

If you have acquired adrive system with mechanical release, please note the

following:

A enables you to move the drive manually in an emergency.

Actuate the mechanical release and move the drive into the desired position.

Once the ER or GQR is released and the drive system is restarted, the clutch

automatically re-engages. The drive system is ready to be operated again.

The is available as either a quick release for continued use (”GQR”,

see page 11, 12) or as an emergency release only (”ER”, see page 10), i.e. to be used only

in an emergency.

The electric adjustment drive is not intended for use by small children

or the unsupervised infirm.

The electric adjustment drive is not a toy for children to play with.

Attention!

Caution: Depending on version, it is possible that theapplication could lower

itself under its own weight. If application is not possible to sink down

with own weight, you must press down the right side of application.

procedure. Engagement or partial engagement of the clutchcan destroy the ER

system.



Before actuation the drive or corresponding furniture component must be load-free.

The emergency release (ER) is not designed for continued use and should

therefore only be used in an emergency.

The actuating mechanics are directly connected to the housing, attaching a

Bowden cable is not possible.

The disengaging lever must be fully actuated throughout the entire adjustment
