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 toothed belt runs exactly parallel to the door.
The door actuator with rope 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: Please make sure during installation that the adjusting
Ill. 3a
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 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).
