When installing and using the DICTAMAT 50 BK-Z with revolving toothed
belt make sure to observe all information and advice of this manual. Du-
ring the installation we recommend to wear protective gloves to prevent
any risk of getting hurt by sheet edges.
The casing of the spring rope pulley may never be opened as the released
spring can cause major injuries. If the spring rope pulley should for some
reason no longer work properly the complete device has to be replaced!
It has also to be assured that the spring rope pulley, the radial damper
and the idler pulley are protected in order to prevent fingers being
trapped (protection cover!).
The closing speed has to be adjusted at the radial damper so that the
door can easily be stopped by hand at every position, making sure
nobody will be endangered.

C) Installation of the DICTAMAT 50 BK-Z
1) Determination of the
Installation Position
Ill. 3a
With the DICTAMAT 50 BK-Z the spring rope pulley can be installed
either on the left or right side of the door. Usually the radial damper
LD 50 is installed beside the spring rope pulley (see ill. 3a and 3b). In
case of space problems there can be exchanged e.g. the positions of
the radial damper and the idler pulley.
The closing direction determines the position of the spring rope pulley.
With a DICTAMAT 50 BK-Z the door always closes towards the spring
rope pulley. I.e. when it is mounted on the right, the door closes to the
right. The same applies when the spring rope pulley is mounted on the
left side of the door.
The damping direction shown below has to be observed when in-
stalling the radial damper according to point C2!
Ill. 3b

IMPORTANT: When choosing the fixing point of the rope of the spring rope pulley, you have to make
sure the working travel of the spring rope pulley allows the complete travel of the door!

In addition to the installation positions shown on the previous page, it
is also possible to fix the toothed belt above the rail. Depending on the
structural conditions on site also other installation positions are possible.
The only thing you have to pay attention to is that all components of the
DICTAMAT 50 BK-Z are properly arranged to each other.

Ill. 4
Depending on the mounting situation it is also possible to fix the spring
rope pulley above the revolving system. For this type of installation you
need an extra idler pulley (part no. 701011) for the rope. This is not
included in the standard delivery. Please keep in mind that the shown
installation positions are just examples which may vary accoding to the
structural conditions.

2) Assembling and
Installing the Radial
Damper, Determining
the Damping Direction
The radial damper LD 50 offers many different possibilities of installation,
depending on the available space.
1. Step: Fixing the mounting brackets to the radial damper
- Determine at which position the brackets shall be screwed to the radial
damper.
Possible mounting positions: horizontal or vertical
The adjacent illustrations show some examples.
In case the included brackets should not be enough, there are additional
fixing accessories available.
- Screw the brackets to the radial damper (4 screws TORX T20 are
included, max. tightening torque 2 Nm).
2. Step: Fixing of the toothed belt disc
- Deciding on the damping direction (the default toothed belt disc has a
freewheel in one direction)
- Check in which direction the toothed belt disc damps (just put it on the
axis and test)
- After having decided on the damping direction (= rotating direction of
the damper during closing), fix the toothed belt disc on the axis of the
radial damper according to the illustration 7. Keep also in mind the
illustrations 3a and 3b.

DICTAMAT 50 BK-Z
C) Installation of the DICTAMAT 50 BK-Z - cont.
Generally the spring rope pulley and the radial damper are installed
below the rail either on the right or left rail end. Depending on the type
of rail it is sufficient to fix the brackets with M5 screws and nuts. If ne-
cessary you can place some washers in the rail.
Further possibilities are the installation on the wall or ceiling. Usually
spring rope pulley and radial damper are installed beside each other
(see ill. 3a and 3b of point C1).
The idler pulley is then installed on the opposite side of the door. Please
make sure the revolving belt runs exactly parallel to the door. The door
actuator with belt tensioner is fixed more or less at the middle of the door.
If you prefer it, you can exchange the position of the radial damper and
the idler pulley.
IMPORTANT: During installation please make sure that the adjusting
screw of the radial damper stays accessible once mounted (see ill. 8).
Place the ends of the toothed belt in
the casing of the door actuator with
belt tensioner (see adjacent ill. 9a).
For this purpose loosen all screws as
shown in ill. 9b and open the tensioner.
On the left side you can jam the loose
end by means of a Ø 3 mm pin. You
have to fold over the belt and return
the loose end into the tensioner. Now
place the 3 mm pin between both sides
of the toothed belt (see ill. 9c).

Before finally tensioning the revolving toothed belt, you have to check
again whether the toothed belt is perfectly aligned. If necessary, once
more align the LD 50 radial damper, the idler pulley and the door actuator
by means of the oblong holes.
For tensioning the toothed belt the belt tensioner may be open or closed.
But you have to make sure that the attachment screw (see ill. 11a) has
been removed before.
The toothed belt is tensioned by means of the internal hexagon SW 5.
Turn it until the toothed belt has the desired tension. The tension shouldn't
be either too soft or too strong. With a too soft tension the toothed belt
still sags. Is it tensioned too much, this causes high friction which will
reduce the closing force. When you have achieved the desired tension,
make sure no tooth is visible in the hole (see ill. 11b). Now screw in the
attachment screw.
6) Tensioning of the
Revolving Toothed Belt
Depending on the installation (ill. 3a and 3b), the Kevlar rope is either
directly fixed to the door or a wheel hanger, as shown in ill.10a or 10b.
To reduce friction on the wheel hanger, please make sure that the rope
of the spring rope pulley always pulls straight and the wheel hangers
don't become wedged. The optimum would be if the rope was aligned
with the X axis of the door.

D) Installation of the DICTAMAT 50 BK-Z on Double-
Leaf Doors
Function: The door actuator for the second door leaf is fixed to the
other part (upper or lower, ill.12) of the belt so that the second door leaf
is moved automatically by the revolving belt.
Installation:
Fix the door actuator for the second door leaf (Ill. 13) approximately
in centre of the second door leaf. The position has to be choosen so
that the clamping plate is at the height of the revolving belt it has to be
attached to.
Unscrew the clamping plate and position the toothed belt so that it is
plced between the two screws. Now put back the clamping plate and
tighten it.
IMPORTANT: The door actuator for the second door leaf has to be the
last to be mounted, when the belt is already tensioned.
2) Fixing of the Second
Door Leaf
With a DICTAMAT 50 BK-Z you can also move double-leaf doors.
Requirements:
- Simultaneous opening/closing of both door leafs (central closing!)
- Both leafs have the same dimensions.
- The force according to point E1 is sufficient for the double-leaf door.

Open the door completely (max. opening 1.5 m). There have to be
left at least 1.5 windings of rope on the spring rope pulley. The spring
is pretensioned by the tensioning screw SW 17 that is accessible from
both sides in the direction of the arrows "spannen" = tensioning (ill. 14a
- 14c). Maximum pretension: 2, 4 respectively 5 revolutions depending
on the used spring rope pulley (see table below)!
Releasing: in case the spring had been tensioned too much, the preten-
sion can again be reduced by turning the tensioning screw against the
direction of the arrow.
The diagram below (ill. 15) indicates the closing force of the spring rope
pulley in relation to the pretension and the door width.
