TABLE OF CONTENTS

The door should be counterbalanced.
If this is not done then additional
measures must be taken, such as
unwinding protection, to guarantee
proper operation. In the case of DKA
drives unwinding protection is
standard! Non-movable or stuck
doors must be repaired. Doors, door
springs, cables, pulleys, retainers and
rails are under extreme tension in
such situations and this can lead to
serious injuries.

Do not attempt to loosen, move or
realign the door yourself.
Contact your maintenance service.

Suitable protective clothing should be
worn during maintenance or installation
of the door opener. This includes safety
glasses, back supporting belt, and
protective gloves. When installing or
maintaining a door opener no jewellery,
watches or loose clothing may be worn.
When working from ladders or on
extended platforms the corresponding
safety procedures must be followed.

To avoid serious injuries resulting from
getting tangled or caught in the
mechanisms, all ropes and chains,

which are connected to the door,
must be removed before installing the
door opener.

During installation and connection of the
electrical supply the local building and
electrical regulations must be followed.
Power cables may only be connected to
a properly earthed network.

This system must not be installed in
damp or wet rooms.

Work on the door opener may only be carried
out by one (1) person working on his own.

When working on the door opener all
the local safety regulations must be
observed. Installation of this device
must be done according to EN12453.

The force on the closing door edge
must not exceed 150 N(15kg). If the
closing force is set to more than 150N
then the corresponding additional
safety accessories must be installed
(see "Installation of safety appli­cations"). The force must never be
set to move a stuck door.

Too high a force leads to faults in the
proper operation of the reversing system
or to damage to the door.

To remind all operators of the safety
procedures the corresponding warning
sign should be attached beside the
operating control unit.

To avoid damage to the door all the
blocking devices should be deactivated.
If however the blocking devices must
remain in operation an unlatching switch
can be installed.

The three-switch block, main dis­connecting switch and all other
control devices must be installed
within view of the door and out of
reach of children. Children should not
be allowed to operate switches or the
remote controller. Misuse of the door
opener can lead to serious injuries.

The door opener may only be
operated if the operator can see the
whole door area, if it is free from
obstacles and the door opener is
properly adjusted. No one may pass
through the door while it is moving
and children must not be allowed to
play in the vicinity of the door.

Before carrying out repairs or re­moving the covers on the door
opener, it is essential to ensure that
no one can inadvertently start the
drive by installing a lockout device or
disconnecting the cables.

This symbol means "Caution" and stands in front of safety advice intended to avoid
personal injury or material damage. Please read such advice carefully. The door drive is of
course designed and tested for safe operation. It is however only possible to guarantee this
if the following safety instructions are accurately followed during installation and operation.

This symbol is intended to advise that if the respective instruction is not followed serious

personal injury or material damage can occur.

GENERAL INFORMATION

5

The drive may only be installed:

If the details on the rating plate on the drive correspond with the mains voltage.
If the drive is undamaged
If the ambient temperature is between 0 and 40°C
If the installation height is not more than 1000m above sea level
If the type of protection has been appropriately selected.

Output shafts and mounting surfaces are to be thoroughly cleaned to remove the corrosion protection agent (use standard
commercial solvent). To avoid material damage the solvent must not get onto the sealing edges of the rotary shaft seals.
Abrasive agents must not be used.

To avoid shaft breakages and hence serious or fatal injuries it is essential to note the following during mounting:

The precondition for suitable dimensioning of the shaft with respect to its fatigue strength is stress-free installation and an
immovable bearing device for the gearbox support as well as any additional or essential supporting bearings in each
direction as supplied by the user.

The machine frame and force introduction points are to be designed with respect to construction and strength according to
the bearing forces which arise. The gearbox housing with two bearings and all the other bearing points are located on a
common, stable framework on which the bearing surfaces have been machined in one operation. Thereby the installer
must ensure that any deformation of the frame under load will not have any negative influences on the shaft load. The
screws may only be fully tightened once the gearbox has been accurately aligned. Installation in damp rooms or in the open
air is only permitted following agreement with the manufacturer. If the drives are stored for a lengthy period of time it is also
necessary to discuss this with the manufacturer.

PREPARATORY MEASURES

Before starting the installation work make sure that all the

necessary safety measures have been implemented.

1. Installation

Place machine down on smooth mounting plate or aligned slide rails and tighten fixing
screws uniformly.

Make sure beforehand that:

The drive is not damaged or sticking
The drive has been reprepared after a lengthy storage period
The supply line is switched off and safeguarded against being switched on again
(VDE regs.) (VDE = German assoc. of electronic engineers)
The connections have been made properly
The turning direction of the geared motor is correct
All motor protection devices are active
No other danger sources exist

NEC LIMIT SWITCH WITH ILLUSTRATION

Limit switch setting:

The limit switch is delivered in a non-adjusted state. It has two all-purpose cams which each consist of an operating
limit switch and a safety limit switch (black and yellow cams) and potential-free contacts (grey, white and blue
cams). The design of the new cams significantly simplifies the setting of the end positions, since both the end
position as well as the respective safety limit switch can be set in one movement.

The limit switch configuration is explained in the illustration above. Move the door in "dead-man" state to the
end position to be set and place the adjusting screwdriver into the stud screw for coarse setting as shown in
the right-hand picture. Set the all-purpose cams for the corresponding end positions (BLACK for UP and
YELLOW for DOWN) so that the microswitch is almost actuated.

Note: Take note of the approach direction of the cam to the microswitch. Tighten the screw thus
safeguarding the cam from turning.

Now turn the fine setting screw on the operating limit switch until the limit switch is actuated. Check the end
position in travel operation. For re-adjustment purposes the door should always be travelled about 0.5 m
away from the respective end position.

In the normal situation it is not necessary to separately set the safety limit switch since delayed switching of
the safety limit switch is guaranteed due to the special shape of the actuating noses on the all-purpose
cams. This means it is unimportant from which side the microswitch is actuated. However in the normal
case the safety limit switch should be actuated about 10 cm after the normal end position has been
reached. It is possible to alter this switching point at any time by means of the "Safety limit switch - fine
setting" (see picture at top right).

Repeat the procedure for the other end position. If the safety limit switch is actuated an error is displayed
optically in the case of GAROG processor controllers. Don't forget that after finishing the setting work the
coarse setting screws must be tightened up so that the limit switch cannot move during door operation. The
cams in the supplementary contacts, which can be overrun, can only be adjusted with the coarse setting
screw.

Two freely-adjustable changeover contacts
(grey and blue cams) are fitted to plug-in terminals.
A third switch is set as a pre-limit switch (white cam).
