Please bear in mind that installing mechanical

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
(b)
(a)
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.

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.

any time, also in the loaded state.
Thread the Bowden cable fully through the groove in the

The tension of the Bowden cable should be too tight, otherwise this could result
in unintentional disengagement or cause the clutch in the GQR's gear system to
slip which in turn can lead to damage.
In order to ensure that the GQR functions correctly, a release travel of 5.5mm ±
1mm be maintained to enable actuation of the Bowden cable.
The Bowden cable must now be tested to ensure that it is in perfect working order.
The GQR system is designed as a standard feature to be used for applications in the
