Make sure that the track rollers can be turned easily
by hand.
4.5.5 Mounting the lock section
Fig.
a
, Page A20. Position the lock section (67) in
the door frame and secure it against toppling over.
When inserting the section, check groove and spring
connector between the sections for proper fit.
Fig.
b
Screw the lock section to the bottom sec-
tion (44) below on the external hinges (48), then
mount the upper tandem wheels (56) in the same
way as for the bottom section (44). When screwing,
observe the permissible torque of 10 Nm.
4.5.6 Mounting the lock (optional)
Mount the lock set to the lock section according to the
illustrations.
Fig.
a
, Page A21. Insert the lock plate (72) with the
cover plate (71) from the outside into the rectangular
hole on the lock section (67), then screw it in place
with the lock set (73, 76) from the inside by means of
the screws (S1).

b
Push the outer handle (70) through the holes
of the lock (the rotating arm must point upwards) and
screw the outer handle (70) together with the inside
handle (78) from the inside by means of the
screw (S2).

Insert the bolt bar (80) into the bolt catch (79).
Fig.
d
Insert the other end of the bolt bar (80) into
the rotating arm (77) and fasten the bolt catch (79) to
the lock section by means of the screws (S10). In do-
ing so, observe the permissible torque of 10 Nm.
4.5.7 Mounting the middle section(s)
Position the middle section(s) (86) in the door frame
and mount them in the same way as for the lock sec-
tion or bottom section.
4.5.8 Mounting the top section
Position the top section (87) in the door frame and
secure it against toppling over. Screw the top sec-
tion (87) to the section below on the external
hinges (48).
Fig.
a
, Page A22. For both the left and right side of
the top section (87), prepare a roller block (88R/88L)
with a track roller (90R/90L) by screwing both to-
gether hand-tight with the screws (S5; S12).

When installing a NovoPort drive, the
outer ring of the upper track roller (90R/90L) or
(105R/105L for HL) must be dismantled on the drive
side.
Take the track roller into your right hand. Place a
screwdriver between rib and tooth of the track roller.
Turn the track roller to the right to loosen the outer
ring and to pull it off.
Fig.
d
Using the screws (S10), mount a preas-
sembled roller block (88) on the left and right of the
top section (87). In doing so, observe the permissible
torque of 10 Nm.
Fig.
e
For hand operation and NovoPort drive: Posi-
tion the centre of the track roller in a way that it is
centrally aligned with the inner edge of the tail end.
Observe that the track roller must be positioned by
approx. 25 mm to the top when operating the system
with a ceiling pull drive.
4.5.9 Mounting the middle hinges
Fig.
a
, Page A23. After the assembly of the indi-
vidual door leaf sections (44;67;86;87), mount the
middle hinges (48) using the screws (S13). In doing
so, observe the permissible torque of 10 Nm.

Tensioning the torsion springs
4.6.1 Tensioning the torsion springs
Hazardous tensioned springs!
WARNING
Springs are under high torque and can
release large forces when being ten-
sioned or when being relieved from ten-
sion.
•
Wear suitable personal protective
equipment when tensioning the
springs or when relieving them from
tension.
Fig.
a
, Page A24. For tensioning the torsion spring
shaft (35R/35L), use both tensioning bars (92) and
tension the spring (35R/35L) into the direction of the
arrow. Generally, the spring is to be tensioned from
the bottom to the top. The number of tensioning re-
volutions is specified on the type plate. Both springs
must be tensioned with the same number of tension-
ing revolutions. The number of tensioning revolutions
can be determined at the tensioned spring according
to Fig.
b
.
Fig.
b
Once you have reached the respective num-
ber of tensioning revolutions, firmly tighten the spring
clamping head screws (S11).
Fig.
c
Once the spring has been tensioned, check
the garage door for correct function. Also check
whether there is enough tension on the pull cords
when the door is open. Only after the function check,
pull the R-pin (97) with mounting lug to unlock the
spring fracture detection function.
NOTICE
Potential triggering of the spring
fracture detection function caused by
loose pull cord!
If the door is closed, at least 2 safety
windings must remain on the cable
drums.
Fig.
d
In case of a spring fracture, the R-pins (97) for
the spring fracture detection function must remain on
the door. Suspend each of the R-pins (97) on the left
and right side of the angle frame (1L/1R).
