motor unit output shaft at the centre.

4.4. ASSEMBLY SEQUENCE

Begin installation with the garage door closed and the operator
released (see section 8).
1. Determine the position of the operator shaft as follows:
a– single section outward swinging garage door (fig. 8)
When the door is closed, the axis of rotation of the drive shaft
must be about 10 cm lower than the axis of rotation of the door.
The telescopic arms must be attached as close as possible to
the point where the door arm is fixed.
b– double section garage door (fig. 9)
When the door is closed, the axis of rotation of the drive shaft
must be about 10 cm below the axis of rotation of the door
hinge. (a).
The telescopic arms must be attached as close as possible to
the point where the hinges are fixed to the door. (b).
c– garage door with horizontal guides (fig. 10)
The axis of rotation of the drive shaft must be halfway between
the two bearings.
The telescopic arms must be attached as close as possible to
the point where the upper and vertical guides meet.
2. Fix the back plate to the reinforcement ribbing of the door pa-
nel using suitable screws for the door's structure. It is advisable
to use nuts and bolts.
Position the back plate in such a way that the end with
the reference marking "E" is facing upwards. This reference
marking indicates the point at which the control unit is to be
positioned.
The back plate has a series of Ø 8mm holes which, when it is
fixed, allow the operator to be installed at various heights.
Check that the fixing position of the back plate allows the
operator to be installed in accordance with the previously
determined shaft position.
In double operator installations, both shafts must be aligned
at the same height.
3. Fix the operator to the back plate using the nuts and bolts
provided, as shown in fig. 11.
4. Weld the upper telescopic arm fixing brackets in the position
described in the instructions for the specific type of garage
door.
In the case of curved arm installation, the brackets can be
welded directly to the existing door arms.
5. Fix the outer profiles of the telescopic arms to the brackets using
the pins and the nuts and bolts provided, as shown in fig. 11.
6. Fit the transmission shafts firmly onto the drive shaft and cut
them to size as shown in figs. 6 and 7.
If limit switches are used (not for Slave), first fit the cams as
shown in fig. 11.
7. Mount the brackets on the transmission shafts and fasten
them to the door panel using screws, taking care to maintain
perfect alignment.
8. Tighten the grub screws on the transmission shaft bushings.
Open the garage door and adjust the length of the telescopic

arms as follows:
a– straight arms (fig. 12)
Cut the outer profile at the position of the transmission shaft.
(a). Push the inner profile of the telescopic arm into the outer
profile and cut off at the position of the rotation pin. (b).
a– curved arms (fig. 13)
Place the telescopic arm in position as shown in figure 13. Cut
the outer profile of the telescopic arm at point a. Cut the
inner profile at point b.
Leave a gap of about 1 cm at the ends of both profiles.
10. Fit the inner profile of the telescopic arm to the transmission
shaft and weld securely.
4.5. ADJUSTING THE COUNTERWEIGHTS
On completing mechanical installation, check whether the door
has become unbalanced by the weight of the operator and ac-
cessories. If necessary, change the counterweights.
For optimum balancing, the door should remain in equilibrium in an
intermediate position (45°) with the operator released.
Also check that the door opens and closes smoothly without jerky
or irregular movements.
5. MOUNTING GEARED MOTOR UNIT
Depending on requirements, the geared motor unit can be moun-
ted in two different ways:
• With the drive shaft at the top (fig. 14)
The card support is fixed to the geared motor by means of 4
bolts which engage with nuts inserted in the guides.
Fastening the gearmotor in this way enables you to next install
the encoder.
• With the drive shaft at the bottom (fig. 15).
The card support is fixed to the electric motor cap by means of
4 screws.
Fastening the gearmotor in this way does not enable you to
next install the encoder.
The cover is designed for both applications (note that in the two
cases the release device is located in different positions).
6. START-UP
6.1. CONNECTING ELECTRONIC CARD
Before carrying out any operation on the control unit (connec-
tions, programming, maintenance), be sure to switch off the
power supply.
Follow points 10, 11, 12, 13 and 14 of the GENERAL SAFETY OBLI-
GATIONS.
As shown in fig.3, prepare the conduits and make the electrical con-
nections between the control unit and the chosen accessories.
Always route the power cables separately from the control and
safety cables (pushbuttons, receivers, photocells, etc.). Use sepa-
rate sheaths to avoid electrical disturbance.
Follow the instructions provided with the control unit and program
it according to your requirements.
6.2. CHECKING DIRECTION OF ROTATION
1. Turn off the power supply to the system.
2. Move the door manually to its half open position.
3. Lock the operator (see section 9)
4. Turn the power supply back on.
5. Send an open signal (START) and check that this causes the
door to open.
If the door closes, invert the electric motor phase wires on the card
terminal block (brown and black wires).
In the double operator installation, connect the same colour wires
to the COM, OP and CL terminals on the control card and the
courtesy light card. If you have to invert the wires, invert them on
both motors.
6.3. ADJUSTMENT OF LIMIT SWITCHES (not for Slave)
• Open the door as far as required, then turn the cam until it just
trips microswitch FCA (fig. 11).
• Close the door, then turn the cam until it just trips microswitch
FCC (fig. 11).
If you are using a control unit with deceleration, advance
the activation of the microswitches.
• Tighten the screws on the cams.
6.4. MOUNTING COVER
• Fasten the cover in place by tightening the four screws at the
sides.
• Push the 2 plastic caps onto the side slots on the cover not used
by the operator shaft.
• Push the plastic cap onto the unused front slot on the cover for
gaining access to the release system.
7. TESTING THE AUTOMATION SYSTEM
Thoroughly test operation of the automation system and all acces-
sories connected to it.
Give the customer the page entitled "User's Guide" and demon-
strate how the automation system is used.

8. MANUAL OPERATION

The operator is equipped with an emergency release device that
can be operated from inside the garage. On request, a lock can
be fitted to the door panel to allow the release device to be ope-
rated from outside.
