SSEMBLING THE BOOM
Then assemble the barrier arm in three phases as follows:
1 - Following components must be assembled before final installation:
rod and rod support, by means of the four allen screws as supplied,
and a 6 mm allen key (for better identification see figures 3 - 10).
2 - The barrier is supplied with the balancing spring decompressed so
the barrier arm and its attachment must be inserted, in vertical
position, into the barrier arm fixing attachment.
3 - Install the rod and fasten with the allen screw as supplied, by means
of a 8mm allen key, and insert the caps.
The gear unit is irreversible so no kind of external locking device is
necessary to keep the barrier in securely closed position.

DJUSTING THE BALANCING SPRINGS
No balancing springs are generally supplied to you with the barrier.
It is therefore necessary to buy balancing springs of the kind and
number corresponding to the length and kind of the boom, and to the
kind and number of installed accessories.
If the boom tends to drop too quickly when the operating device is
released, adjust the balancing springs in the following way:
1 - When the gearmotor is blocked, lift the boom operating the electric
commands, until it reaches its vertical position.
2 - After having interrupted the power supply to the motor, screw
clockwise the ring nut for the balancing unit adjustment, thereby
increasing the compression degree of springs during the movement.
Use the second ring nut to block the first one.
To check the boom is balanced perfectly, release the gearmotor and
move the boom by hand. The boom should slightly tend to rise (Pic. 4).

IMIT SWITCH SETTING
Normally the barrier is supplied to you with the limit switches already set
to allow optimum barrier movement.
If the base plate has not been cemented in on a level plane, the boom
might be not perfectly horizontal or vertical, with the result that the
aesthetic appearance of the installation is poor.
To avoid this, it is possible to alter the trajectory of the boom by adjusting
the mechanical and electrical limit switches (Pic. 5):
1 - With the barrier up, use a no. 19 hexagonal wrench to loosen the
retaining nuts (A) and a no. 8 Allen key to loosen or tighten the
countersunk screws (B) for setting the mechanical limit stops so as
to delimit the arc described by the barrier boom.
2 - Having done this, the limit switches now have to be set so as to
determine the electrical operation of the motor for the new trajectory
described by the boom. To do this, you must use a no. 3 Allen key to
release the two limit switch adjusting cams (C). Once the boom is
positioned in accordance with the mechanical stop, you need only to
rotate the cam involved so as to trip the limit switch.
3 - Once this is achieved, retighten the cam.
NB: If during operation there is no slow down movement, please note
that this cannot be necessarily caused by the control panel failure.
In fact, the absence of the slow down movement can be caused by
the incorrect adjustment of the electrical limit switch cams.
Especially when the barrier is opening (or closing) and the slow
down electrical limit switch is pressed, if the other slow down limit
switch has not been released, the slow down movement does not
operate. In order to eliminate this problem it is enough to increase
the distance between the two cams.
