2. Installation
a) Place the track on a flat surface and lay it as shown in Fig.3
b) Referring to Fig. 4, align both ends of the tracks and fit them with
the two plates P, by using the eight M6X16 screws, the nuts D
and the washers R.
c) Make sure that the belt is correctly tensioned. If necessary, it
can be adjusted through nut D, as shown in Fig.5.
The correctly tensioned belt keeps its position along the entire
track, without bending, but still resilient at a slight pressure by
hand.
d) Move the drive carrier (Fig.6) until the pulley housing (ref. S of
Fig. 7) touches the motor shaft pin (ref. P of Fig. 7)
e) Fix the track to the basis of the gear motor, as per Fig.7. Fit
the track to the basis of the gear motor, with the five D4,8x38
screws.
f) Fit the hooking bracket S to wall (Fig.8) or ceiling (Fig.9). Mark
the two fitting points corresponding to the centre of the door.
Hook the track to the bracket and fix it by means of nuts M and
washers R. Rest the gear motor body on the floor.
If there is not enough space to use the bracket S, the track can be
fixed directly to the ceiling through the holes shown in Fig.10.
g) Position the fitting brackets to ceiling by means of the special
housings in the track, near the gear motor (Fig.11) and fix them by
means of screws M and nuts D. Two fitting brackets for mount-
ing to ceiling are supplied with PTC.4 and PTC.L4 tracks. They
must be fitted near the joining point of the tracks.
h) By using a ladder, hoist the gear motor (Fig.12), mark the fitting
points of the brackets, drill the holes and fix the gear motor by
means of screws and screw anchors suited to the material.
i) temporarily fix the opening and closing mechanical stoppers, at
beginning and end of track, by using the screws K, as highlighted
in Fig.13a. At the end of the adjustment phase of the automatic
system, the stoppers will be positioned more precisely and firmly
fixed to the track between the 2 screws X, while drilling two holes,
as indicated in Fig. 13b.
Note: while making the holes, take care not to drill the stoppers as well.
l) Connect the driving rod A to the drive slide by means of the
M6x20 cylinder head screws and the self-tapping nut. The rod
movement should not be obstructed. Fix the bracket S to the
door so that, with closed door, the rod A is in an almost vertical
position. Shorten the drive rod A, if required.
In the event of heavy doors, it is recommended to use both upper
and front holes.
m) Insert the cord in the release lever and in the knob. Make a knot
as indicated in the detail of Fig.14.
n) Apply the warning sticker supplied to the door:
3. How to store the opening and closing positions in memory
The gear motor is equipped with a control unit with a memorisation
function of the opening and closing positions. The memorisation
procedure is described in instructions supplied with the control
unit and requires the positioning of the mechanical stoppers, cf.
Fig.13.
4. How to regulate speed
On the transformer, two faston terminals are provided, indicated
as F1 and F2 in Fig.15.
Faston F1 (white) regulates the opening and closing speed of the
door and can be preset on three voltage positions:
JM.3:
• 20V: for sectional and balancing doors
• 28V: for sectional doors only
• 35V: for sectional doors only (8.9 m/1')
JM.4:
• 20V: for sectional and balancing doors
• 28V: for sectional doors only
• 35V: for sectional doors only (8.9 m/1')
12
Faston F2 (red) must not be moved from 20V position.
WARNING!: The adjustment of the door movement speed af-
fects the safety level of the automatic system.
Comply with regulations in force.
5. Accessories (optional)
JM.CB Emergency Battery Kit:
It permits the operation of the automatic system in the event of
power failure.
The kit is composed of: battery charge card, 2 batteries at 12V,
fitting bracket, screws and cables.
The batteries must be installed on the upper part of the gear motor
basis, as per Fig.16.
To connect batteries, please refer to specific instructions.
Note: Once installed, the batteries protrude from the track upper
profile by approx. 10mm.
JM.PP Cord Manual Control:
It permits the control of the automatic system from indoor by means
of a cord, thus avoiding the installation of a keyboard. The kit is
composed of: micro-switch group, cord control with knob, spring
and cables (Fig.17)
For the installation, please refer to specific instructions.
Fig.19 shows the cord in working position.
6. Manual operation from outdoor
In sectional doors, the system can be released also from outdoor
by using item JM.SF (Fig.19).
A. Insert the metal cable in the slide, as indicated in Figure 19.
B. Fit the adjuster on the bracket and insert the sheath.
C. Fix the other end of the cable to the release device. The figure
shows an example of connection to the garage door handle
AU.MS.
N.B.: Any type of cord release device can be used under the
condition that the release stroke is of at least 15 mm.
If the device is able to keep the lever in the release position (e.g.
AU.MS) it would be easier to cut the hooking lever, as shown in the
detail of Fig. 19. In this way, by moving the handle in the original
position, the automatic operation is reset.
7. Assembling onto balancing doors
Overhead door with balanceweights (fig.20): these doors need the
special arm art. AU.C25.
In order to assemble it make sure that:
• the arm is fixed to the top edge of the door.
• the arm is levelled.
The civil liability policy, which covers possible injuries to people or
accidents caused by defects in construction, requires to use original
Benincà accessories.
