2) Fasten the geared motor (axis in the chosen position) to the support
base "
A
", with the night light facing towards the top, using the two
previously removed screws and lock nuts.
3) The telescopic arm fastening brackets "
G
" can either be welded to
the fixed frame of the garage door (reinforce the welding area if the
metal sheet is less than
2,5 mm
thick) or fixed to the frame/wall using
two M8 bolts. At this point slide the tube "
H
" between the arms of the
bracket "
G
" and fasten down (don’t over tighten) using the supplied
M8 x 25 screws and lock nuts.
To guarantee correct operation the tube "
H
" with its straight arm
inserted must be able to move within a minimum space of
20 mm
between the door arm "
C
" and the counterweight housing "
L
". If the
available space is inferior you will have to use a curved arm.
4) Place the tube "
H
" (with the arm "
R
" inserted) parallel to the counter-
weight housing "
L
" and measure the distance "
W
" between the end
of the motor shaft "
S
" and the internal part of the straight arm "
O
"
as shown in the drawing. Subtracting
63 mm
from the distance "
W
"
will give you the overall length of the motor shaft extension tube (fig.
2,3). Follow the same procedure to measure the cutting length for the
other extension tube. Remember to file down the sharp edges after
cutting.
5) Position the support brackets "
M
" (fig.9) at the same height as the
geared motor axis and drill two
Ø4 mm
holes with which to fix the
bracket to the garage door framework.
6) Assemble the
316/GLOTG
group (fig.2-3) motor shaft extension tubes,
threaded joints and relative supports and then fasten down the support
tubes using the supplied
4,8 x 16
self-tapping screws.
7) Measure the distance between the motor axis "
P
" and the axis of the
telescopic arm hinge hole "
Q
" with the garage closed "
x
" and with
the garage door open "
Y
". Cut the tube "
H
" and straight arm "
R
" to
the minimum measured size (minus a play of
2 cm
).
Remember to file down the sharp edges after cutting.
Reassemble and fasten down
the arms using the supplied
M8 grub screws.
8) Drill the extension tube as
follows:
- Make sure that the garage
door is closed and the
geared motor is free;
- Using a
Ø10 mm
drill bit make
a hole in the centre of the joint
"
N
" (fig.2-3) which passes half
way through the tube.
- Insert the
Ø10x50
elastic pin
halfway through the tube.
- Open the garage door and drill
the joint from the other side then
allow the elastic pin to outcrop
the same distance on both sides
of the joint.
9) Check that the door is well balanced by manoeuvring it manually.
The weight of the motor means you will have to increase the counter
weights by
4-5 kg
on each side.
Compensate the counter weights until the garage door is perfectly
balanced.
Fitting the motor laterally
Once you have decided upon the correct assembly diagram follow points
1,2,3 and 7 of the previous paragraph. In this case there are two motor
supports and they should be fixed to the extreme right and left of the
garage door maintaining a distance of
65mm
from the counterweight
housing as shown in the drawing.
Insert the threaded joint of the telescopic
arm directly into the threaded shaft of the
motor, push it well in, and fasten down
using the supplied grub screw.
Check that the door is well bal-
anced by manoeuvring it manually.
The weight of the motor means you
will have to increase the counter
weights by about
10kg
on each
side.
Compensate the counter weights
until the garage door is perfectly
balanced.
Fitting the manual release cord
(fig.6)
- Position the setting support bracket "
d
" about
100 mm
above the
garage door lock (in line with it) and fasten down using 2 rivets.
- Mount the setting screw "
C
" with its relative nut and lock nut (one for
each motor) and leave a space in order to allow adjustment later.
- Carefully insert the spring mechanism "
G
" into its seat on the base
"
H
" so that the tab "
F
" moves the lever "
L
" (fig.6a) while it rotates and
then fasten down using the two 4,8 x 13 self-tapping screws "
I
".
If the unit has been correctly assembled you will be able to tighten
down the two screws without them interfering with the rotation of the
spring mechanism.
The spring mechanism moves the lever "
L
" into the release position
when the cord "
N
" (fig.6b) is pulled.
- Mount the spring "
M
" by inserting its hook "
P
" into the opening "
Q
"
(fig. 6b) and fasten the other end "
R
" using the 4,8 x 13 self-tapping
screws "
O
".
- Insert the cord "
N
" through the hole on the spring mechanism and then
into the corresponding hole on the base "
H
". Work out the required
length of the sheath "
E
" and insert the cord. Use a little oil or grease
to extend the lifetime of the cord.
- Pass the cord through the setting screw "
C
" and fasten down using the
screw "
B
" of the lock "
A
" after having tightened the cord and having
wound half a turn around the screw.
The M8 serrated washer placed below the screw will fasten the cord
into position.
- The manual release mechanism is working correctly when a
90°
rota-
tion of the door handle corresponds to the alignment of the marker
tab "
S
" (fig.6b). The spring mechanism cannot go past this mechani-
cal stop. Use the setting screw "
C
" if any ulterior adjustments are
required.
- In certain cases the spring "
M
" could develop too much force and
pull back the handle of the lock "
A
". If this occurs you may remove
the spring "
M
" (it is not always required) the handle will now remain
in the released position.
Adjusting the travel limit
- Move the door manually to about
50 mm
from the completely open
position.
Release the cam and rotate it until
the microswitch trips.
- Carry out several trial rotations to
make sure it is functioning cor-
rectly.
- To adjust the cam "
A
" you may
also insert a flat nosed screw-
driver into the slit "
B
" and then
rotate the cam in either direc-
tion.
