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-professional operator of the end product.
a) Prerequisites
The MEGAMAT P drive system is only intended for use with corresponding DewertOkin
controls.
In this respect please also refer to the Installation Instructions supplied with the controls.
Caution!
For Your Own Safety!
Before using the crank (see page 5/8), you have to cut the connection of the main circuit
connection and the motor cable of the drive to the control mechanisms. Unforeseen
setback of the crank may cause danger of injuring and/or may damage the drive.
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.
b) Mechanical release functions (quick release)
If you have acquired a MEGAMAT P drive system with mechanical release, please note the
following:
ŸTo 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 5d) or eventually cleaning
including a final check of the quick release and the integration in the service plan of
the application.
ŸA mechanical release enables you to move the drive manually in an emergency.
Ÿ Actuate the mechanical release 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 Once the GQR is released and the drive system is restarted, the clutch
automatically re-engages. The drive system is ready to be operated again.
The MEGAMAT P is optional available as a quick release for continued use (GQR, see
page 10 and 11), i.e. to be used only in an emergency.
c) Electrical Connection
In the Operating Instructions to be issued by you, point out to the operator that if leads, in
particular the connection lead, are driven over they could sustain damage. Mechanical
loads should also be avoided.
When routing the leads make sure that they:
Ÿcannot get caught up or trapped,
Ÿare not subjected to mechanical loads (i.e. do not pull, apply pressure or bend),
Ÿcannot get damaged in any other way.
Make sure that the cables, in particular the connection lead, are fastened to the final
product with adequate strain relief and kink protection and that suitable constructional
measures prevent the connection lead from trailing on the floor when the final product
is being moved.
d) Crank operation
In the event of a power failure it is possible to reset the drive via crank operation. Insert
1)
crank (8) into the hexagonal (SW10,DIN ISO272) receptacle at the rear end of the drive.
Turning crank (8) resets the drive.
Attention: Crank operation is only permissible provided cable (4) is insulated from the
control unit! After operating the drive manually the crank (8), must be
immediately removed from the drive. Otherwise damage could be incurred
due to the crank being turned on subsequent movement of the drive.
1) not presently available in the DewertOkin - product range
Recommended arrangement of the fittings
Besides precise alignment of the fittings, we recommend using only one fixing bracket (a) 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. The actuator must always be fixed, so that it
is restrained, but adequate free to move on its mountings. The actuator must be fixed in such
a way that it is protected from twisting and deformation in all positions. Fittings with two fixing
brackets (b) 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. Recommendation: the elongated hole (c) should offer at least 2mm play.
(a) (b) (c)
e) Dismantling
Operate the furniture to travel to the home position, then insulate the drive from the
DewertOkin controls. When removing security clip (3, 5) and BEK bolts (2, 6), it is
important to support the drive, as this is released instantly!
