DIMENSIONS
Fig.3: Box overall dimensions (mm)
Fig.4: Motor overall dimensions (mm)
Fig.5: Overall dimensions of the installation. The minimum
clearance between a rotation pin and the pier is 60 mm.
In the table of Fig.5, the minimum dimensions required for
the box and the lower profile of the door leaf are shown in
the various release versions. Dimension B is the clearance
between the release and the cover.
INSTALLATION
HOLE AND FITTING OF THE BOX
Dig a foundation hole with indicative dimensions shown in
Fig.6.
Make sure that the centre of the hole is aligned with the
rotation axis of the gate leaf (sectioned line).
Provide for an adequate water drain (Fig.1 ref.17), and pre-
pare the entrance of the cable duct (Fig.1 ref.16).
Water accumulating inside the box is however to be avoid-
ed. Possibly provide for a draining pipe connected to the
nearest drain.
Make sure that the rotating axis of the gate leaf (fig.5 ref. R)
is perfectly vertical and that the box is perfectly flat.
Fix the box with cement.
WELDING OF THE GATE LEAF
Carry out a careful welding of the rotation bracket onto the
entire profile of the gate leaf (Fig.7).
It is possible to avoid welding directly onto the gate leaf by
providing an adequate C bracket to be inserted between
the gate leaf and the rotation bracket (Fig.8).
In addition to the standard installation shown in Fig. 9, the
system can be also positioned as shown in Fig. 10, if the
gate leaves are installed internally.
MOTOR INSTALLATION
Before installing the motor, keep in mind that:
The motor can be assembled onto either right or left gate
leaf.
With reference to Fig. 9, a SX leaf is the leaf on the left,
while a DX leaf is the leaf on the right.
The gate leaf features a 10° hydraulic braking during clo-
sure and 20° hydraulic braking during opening.
Preparation of right and left motors.
With reference to Fig.11, for left motors:
1 Hydraulically release the motor by loosening the V re-
lease screw.
2 Completely turn the output shaft clockwise, until it reach-
es the closed position.
With reference to Fig.12, for right motors:
1 Hydraulically release the motor by loosening the V re-
lease screw.
2 Completely turn the output shaft anti-clockwise, until it
reaches the closed position.
The motors can be also electrically moved to the closed po-
sition by temporarily connecting them to the control unit.
Placing the motors in the box
The operations are similar for either gate leaves:
1 Open the gate leaf so as to facilitate the access to the
box.
2 By referring to Fig.13, lock the bush B on the drive shaft
by means of the grain G.
3 Place the motor inside the box.
On the bottom of the box, a track matching the grove on
the motor is provided.
The motor is correctly positioned inside the box by sliding
the motor onto this track until it clicks.
4 Close the gate leaf until it reaches the gate stop.
5 By loosening the grain G, the bush slides on the motor
shaft, thus connecting the motor shaft to the drive shaft,
Fig.13b.
To perfectly align the drive shaft, the motor shaft might
be slightly rotated.
6 Fix the grain G to lock the bush in the working position,
Fig.13c.
7 Tighten the hydraulic release screw, if previously backed
off.
WIRE CONNECTIONS
For the electric connections of the automatic system and to
adjust the operating modes, see the Operating Instructions
of the control unit.
The motor is supplied with a special pre-cabled, four pole
cable marked as follows:
BLACK: RUN
GREY: COMMON
BROWN: RUN
YELLOW/GREEN: EARTH
Fig.16 shows cabling to be provided for a standard instal-
lation. Before laying the cables, check the type of cabling
required for accessories actually used.
Key of components:
1 SUBWAY geared motor
2 Photocells
3 Key selector or digital keypad
4 Flashing warning beacon
5 Antenna
6 Control unit
7 Electric lock
*
*The installation of the electric lock is mandatory in models
with hydraulic lock or in any case for gate leaves wider than
2.5 m
IMPORTANT: Keep the power cable detached from the
auxiliary ones.
ADJUSTMENT OF THE THRUST FORCE
The operator is equipped with an anti-crash device (by-
pass valves) for the regulation of the thrust on the gate leaf
when it hits an obstacle. Once the obstacle has been re-
moved, the gate carries on its movement for the operating
time preset by the control unit.
With reference to Fig.17:
- Remove the two screws V.
- Remove the protection cap of valves.
- By using a 6mm Allen key, proceed to the thrust regula-
tion.
- There are two adjustable valves, one regulates thrust in
the opening phase (Open), the other regulates thrust in
the closing phase (Close).
- According to the motor positioning (SX-Left/DX-Right)
the opening and closing valves are reversed. Fig. 18
shows the differences between the two positions.
- By turning the valve towards +, the thrust force of the
gate leaf is increased. By turning it the opposite direction
(- ) thrust decreases.
WARNING! This adjustment influences the safety level of
the automatic system.
