Introduction
Thank you for choosing our JM.3T 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.
1. General information
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. 2).
- it has to be possible to open and close the door by pulling
and pushing horizontally its top edge (fig.2).
- manual moves must be smooth and regular.
PTC.3: Pre-assembled track, with 8 mm belt, 2.5m max
height
PTC.4: Pre-assembled track, with 10 mm belt, for doors with
2.5 m max height
PTC.L4: Pre-assembled track, with 10mm belt, for doors
with 3.5 m max height

2. Installation
a) Place the track on a flat surface and lay it as shown in
Fig.3
b) Referring to Fig. 4a, 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.
If PTCL.4 track is used, also brackets F, as shown in Fig.
5, should be used. In this case, pay attention to position
of washers R2, which must be placed between bracket F
and plate P.
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.
If the space available is reduced, the track can be installed
by turning it by 90° with respect to the gear motor base,
as indicated in Figure 7b. In the "DX" position, the power
supply cable hampers the track and should be therefore
disconnected from the control unit and reconnected by
using the alternative cable gland.
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) temporarily fix the opening and closing mechanical stop-
pers, at beginning and end (Optional - art. PTC.STOP) 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 K, 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 (Fig.14). 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
The gear motor is equipped with a control unit with a memo-
risation 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 me-
chanical stoppers, cf. Fig.13a/b.
