Creation of a complete operating instruction manual for the entire end product
These instructions are only intended to be used by the end-product manufacturer. They should not
be given to the operator of the end product. The factual information contained within may be used
as a basis when creating the end-product manual.
The warning and danger notices are best suited for use in the end product's manual. However it is
not sufficient to simply follow these notices. You should also carry out an internal risk assessment
for your end product. This can then be used as the basis for the safety notices in your manual.
These installation instructions do not contain all information required to safely operate the end
product. They only describe the installation and operation of the drive as partially completed ma-
chinery.
The instructions are intended for the technicians responsible for manufacturing an end product and
not for the operators of the end product.

MEGAMAT XS Description
73115 4.0 13
4. Description
The MEGAMAT XS drive is an electrically driven motor that is responsible for moving the end
product in a linear direction. This adjustment is created by the in and out movement of a stroke
pipe. The movements of the MEGAMAT XS drive are controlled using a control unit or a double
drive which is connected to a DewertOkin handset.
The different drive models vary according to their:
•output performance,
•the mounting of the stroke pipe.
We reserve the right to make unannounced technical changes in the course of our continual
product improvement process!
4.1 Components
The main components of the MEGAMAT XS drive are the motor and the stroke pipe. The stroke
pipe is protected by the drive housing when it is retracted. Mounting fixtures are located at the
outer end of the stroke pipe and at the opposite end of the drive. They are used to mount the drive
in the end product.

4.1.1 Stroke pipe options
There are two types of stroke pipes available for different types of applications. The stroke pipe can
be screwed onto the spindle screw or it can be mounted unattached. The drive only exerts pushing
force when the stroke pipe is mounted loosely (unattached). The motions of the drives for these
two versions are shown in the following illustrations.
CAUTION
If the stroke pipe is unattached, then the end product must be designed to prevent the
stroke pipe from coming out during operations. This can be accomplished by imple-
menting a fixed end-stop mechanism (refer to the "Safety notices to observe during
installation" in the "Installation" chapter).

6. Installation
6.1 Safety notices to observe during installation
Basic safety rules must be followed in order to ensure that the end product can be continually op-
erated in a safe manner. These rules must be observed while using the end product and while in-
stalling the drive.
6.1.1 Ensuring operational reliability during installation
The safety and reliability of the end product containing the DewertOkin drive can be ensured by us-
ing the proper construction methods described below.
Avoiding fatigue fractures
CAUTION
Drives that are incorrectly installed can undergo fatigue fractures which then create a
risk of injury.
•Install the drive in the end product so that it is properly aligned. This will help pre-
vent shear stress.
•Do not position the drive at a slanted angle when installing it in the end product. A
slanted angle between the intended direction of movement of the end product and
the drive's direction will create shear stress and could lead to a fatigue fracture.
•Be sure to install the drive so that it can always move freely in all operative states.
•You should never screw the stroke pipe into the drive.
Avoiding a pinching hazard
CAUTION
When designing your product, you should take the drive adjustment movement into
account with passive safety mechanisms and with the appropriate safety notices in
your operating instructions.
•Installation methods for ensuring passive safety: Install the MEGAMAT XS drive so
that none of the positions where shear and pinch hazards exist are accessible ex-
ternally.
When preparing safety notices for the operator, Make sure that your operating instructions inform
the user of these safety points.

Installation MEGAMAT XS
18 73115 4.0
Avoiding an over-extension of the stroke pipe (when mounted unattached)
CAUTION
There must be a fixed mechanical end stop built into the end product for MEGAMAT XS
drive models where the stroke pipe is not attached to the spindle screw. If no fixed me-
chanical end stop exists, the stroke pipe can over-extend. This can cause malfunctions,
personal injury, and damage to the drive system.
Avoiding an overrun of the stop point with the end product
Your end product should contain mechanical end stops. These will limit the drive movement and
significantly increase operational safety. DewertOkin recommends that you build such mechanical
end stops into your end product.
If, for technical or cost reasons, you choose not to use end stops, then we strongly recommend the
use of an additional safety limit switch whenever the DewertOkin drive is being used for at-risk
functions. A safety limit switch will protect the drive from a critical failure and overrun in the event
that the top end switch malfunctions.
The safety end switch shuts the drive down as soon as the normal end switch is passed over.
The safety end switch is integrated directly into the drive and does not require any additional in-
stallation. The drive may take up an extra 23 mm when installed with the safety limit switch.
6.2 Installation procedure
NOTICE
Mount the drive in its unloaded position within your end product.
The drive must either be completely retracted or extended at its end position.
Damage to the drive can only be avoided if the drive is installed in its unloaded position. This
ensures safe installation.

CAUTION
You should never screw the stroke pipe into the drive. A stroke pipe that has been
screwed into the drive can result in fatigue fractures.
5 If the stroke pipe clevis (C) does not align exactly with the gear clevis (E), the stroke pipe may
be unscrewed out of the drive by no more than a half turn.
CAUTION
The stroke pipe may only be turned one half rotation out of the drive. Do not rotate the
stroke pipe further out. An over-rotation can lead to unsafe operations.
6 Attach the stroke pipe (C) using a mounting bolt (D) to the fitting (B).
7 Secure the mounting bolt (D) with the safety clip (A).
8 Now connect the drive to the control unit or the double drive. Ensure that the electrical connec-
tion cable cannot be pulled out.
If the hand switch will be used to control two drives, you must first connect both drives electri-
cally to each other (for example, over a control unit). Then you can connect the handset.
6.2.2 Electrical connection
CAUTION
Electrical components should be connected or disconnected only when the mains
power cord and the battery plug (when present) are unplugged.
WARNING
Only the following personnel are qualified to work on the power cord or to replace the
power cord:
•someone who has completed training in electronic motor assembly,
•someone with equivalent qualifications, or
•someone who has successfully completed the appropriate DewertOkin training pro-
gram.
You should only work on the power cord when you are qualified to do so. Otherwise, a
properly qualified person should be found for this task.
NOTICE
There is a delay after the supply voltage is applied before the device actually turns on.
Wait at least 15 seconds before initial commissioning.
