General Information - Beninca JM.3 Manual Del Usuario

Thank you for choosing our JM.3/JM.4 ratiomotor.
All items in the wide Benincà production range are the result of twenty-years' experience in the automatism sector and
of continuous research for new materials and advanced technologies.
We are, therefore, in the position to offer highly reliable products that due to their power, effectiveness and useful life,
fully satisfy the final user's requirements.
All our products are covered by warranty.
Possible injury to people or accidents caused by defects in construction are covered by a civil liability policy drawn up
with one of the major insurance companies.
The system has been studied to motorize sectional doors.
To be applied onto balancing doors, a special fitting arm is required (item AU.C25).
In any case, following conditions will have to be observed:
- the distance between the door highest point and the ceiling must be at least 40mm (fig. 1).
- it has to be possible to open and close the door by pulling and pushing horizontally its top edge (fig.1).
- manual moves must be smooth and regular.
The gear motor is available in two versions:
JM.3 (600Nm) and JM.4 (1200Nm) to which the following tracks can be matched (fig.2):
PTC.3: Pre-assembled track, with 8 mm belt, 2.5m max height, for JM.3 only
PTC.4: Pre-assembled track, with 10 mm belt, for doors with 2.5 m max height, for JM.3 and JM.4
PTC.L4: Pre-assembled track, with 10mm belt, for doors with 3.5 m max height, for JM.3 and JM.4
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 pres-
sure 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 mounting 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) Fix the opening and closing mechanical stoppers, at both ends of the track, as shown in Fig.13. The position of the
stoppers will be adjusted during the final adjustment of the automatic system.
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.
