a)
Prerequisites
The
MEGAMAT 4 drive system
is only intended for use with corresponding DewertOkin
control units.
I
n this connection please also follow the installation instructions supplied with the
accompanying control unit.
b)
Quick release “GQR”
If you have acquired a
MEGAMAT 4
drive system with
quick release „GQR“
, please note
the following:
Ÿ
To ensure that the function of the “
mechanical quick release, GQR
” is reliable and
remains in the same constant quality, the actuator has to be completely clean. We
therefore recommend an optical check (see chapter 5b) or eventually cleaning
including a final check of the quick release and the integration in the service plan of
the application.
Ÿ
A
quick release „GQR“
enables you to move the drive manually in an emergency.
Ÿ
Actuate the
quick release „GQR“
and move the drive into the desired position.
Caution:
Depending on version, it is possible that the application 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.
Ÿ
When restarting the drive system following actuation of the
quick release „GQR“
,
this automatically re-engages. The drive system is now ready for operation.

Attention!
Ÿ
The electric adjustment drive is not intended for use by small children
or the unsupervised infirm.
Ÿ
The electric adjustment drive is not a toy for children to play with.
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.
Please note:
GQR (Quick Release) features a high quality gear system which can be actuated at
Ÿ
any time, also in the loaded state.
Ÿ
To allow actuation, a suitable commercially available
Bowden cable (2)
is provided.
This is fastened in the
Bowden cable receptacle (1)
(not part of the supply
package).
Thread the Bowden cable fully through the groove in the
Bowden cable
Ÿ
receptacle (1)
and into the cable bolt at the top, then secure the Bowden cable in
place with the
locking pin (3)
.
The tension of the Bowden cable should
not
be too tight, otherwise this could result
Ÿ
in unintentional disengagement or cause the clutch in the GQR's gear system to
slip which in turn can lead to damage.
The
Bowden cable fixture (1)
must be pulled until it meets the end stop (all the
Ÿ
way up) in order to ensure that the GQR functions properly. The clutch on the GQR
opens with a pull force of 110 N or greater. The pull force must not exceed 250 N;
otherwise the GQR can be damaged.
A
spring (4)
must be built into the Bowden cable mechanism to prevent damage to
Ÿ
the GQR and to ensure proper function.
The Bowden cable must now be tested to ensure that it is in perfect working order.
Ÿ
Attention!
The GQR system is designed as a standard feature to be used for applications in the
drive's push
direction
. When actuating the GQR, it is therefore important to ensure that
the manual adjustment takes place in the
intended direction only
.
Non-observance can cause the GQR to sustain damage
.
Moreover, another standard feature of the GQR is the trap protection for emergencies.
Non-designated actuation of the trap protection (operating the quick release
without actuating the Bowden cable in the opposite direction to the designated
direction) leads to increased wear and premature failure of the system.
Please draw attention to this in your operating instructions
.
