To fit the beam, follow the instructions below:
• put the rod carrier plate in vertical position.
• fit the beam, ref.1 fig.9.
N.B.: Beams are ambidextrous
• position the “C” support, ref. 2 fig.9, and tighten the six supplied
screws, ref.3 fig.9.
• adjust the mechanical stops, fig. 10 ref.1 and 2.
• adjust the activation cams, fig. 11 ref.1 and 2, of the stroke-
limit microswitches so that they are activated with the rod in
opening or closing position just before their respective
mechanical stops.

INSTALLING AND ADJUSTING THE BALANCING SPRING.
The automated system requires a balancing spring, fig.12 ref.1,
which must be ordered separately (like the beam). The type of
spring to be fitted must be selected according to the length of
the beam and of any installed accessories (see chap.8), selecting
the spring from among those in the price list.
Spring installation and adjustment procedure:
• check if the operator is released: see chap. 6
• remove the tie-rod, fig 12 ref.3.
• while keeping the beam always in vertical position, connect
the spring to the plate, fig.12 ref.2. For quicker installation, we
recommend keeping the open part of the eyelet facing
toward the installer.
• fit the tie-rod, fig. 12 ref.3, into the lower eyelet and in its
securing hole.
• tighten one of the two nuts, fig. 15 ref.4,
until you recover all backlash on the
spring.
• position the beam at 45° and, turning
the nut you have just tightened, pull the
spring until you balance the weight of
the rod in this position.
• tighten the second nut and secure the
whole assembly.
• restore normal operation as in chap. 7.
5. START-UP
• install the electronic control unit, observing the supplied
instructions.
• check if motor connection is correct, in the following steps:
• set the operator to manual operation, see chap.6.
• position the beam at 45°, so that the two microswitches are
not activated.
• re-fasten the operator, see chap.7.
• power up the system and provide a pulse with the start
command. The first manoeuvre to be performed by the beam
must be opening. If the beam starts with a closing cycle, cut
power and reverse the phase wires of the control unit terminals.
• power up again and repeat the check.
• check the efficiency of the limit-switches, checking the status
of the LEDs on the control unit.
6. MANUAL OPERATION
If the barrier has to be moved manually due to a power failure or
malfunction of the automated system, use the release device as
follows:
• cut power to the system with the master-switch.
• open the door on the upright with the supplied coded key.
• fit the special key, located inside the upright, in the release
hole (fig. 13, ref.1) and turn it anti-clockwise for a few turns until
you reach the mechanical stop limit.
Attention:
The mechanical stop limit consists of a flexible ring (fig. 14 ref.
1) which must not be outdistanced in order not to jeopardise
the operation of the release device.
When the system has been released, the beam could remain
in its initial position. Therefore, the beam must be moved in
both directions until the release system is felt to trip.
• open or close the beam manually.
7. RESTORING NORMAL OPERATION
To prevent an involuntary pulse from activating the barrier during
the manoeuvre, cut power to the system before restoring normal
operation.
• open the rear hood of the upright with the supplied coded
