OVERALL DIMENSIONS AND POSITIONING
- The barrier movement mechanism is easily adaptable to provide
right-hand or left-hand closing (as seen from the barrier side). See
instructions for changing the opening side.
- For safe use, it is necessary to provide suitable space for the
automatism access panel opening (P) and to be able to activate the
unblocking key (CH) for the emergency manoeuvre.
- Secure to the flooring takes place using an anchoring counter
plate equipped with suitable anchor bolts to embed in the jet of
concrete.
The following table summarises the main overall barrier

SAFE OPERATING CONDITIONS:
To operate the barrier:
- Affix the adhesive band with reflective strips onto the barrier arm,
to highlight it;
- Install a fixed support at the end of the barrier;
- Install a system of photocells, as shown in the figure, to prevent
the automatic re-closing system from intervening during the transit
of persons or vehicles;
- Check that, in the open and closed positions, the barrier is easily
visible both during the day and at night. Add suitable additional
lighting where necessary;
- Install a flashing light to activate during barrier movement
(optional)
ADJUSTING THE LIFTING FORCE GENERATED BY THE
SPRING
- After switching off the power supply, access the barrier
automatism through the opening in the panel (P).
- With the use of a CH32 fixed spanner, loosen the lower nut and,
by turning the stainless steel stem by hand, the following occurs:
in a clockwise direction, the length of the threaded bar increases
(the preload increases and counterbalances a longer or heavier
arm).
in an anti-clockwise direction, the length of the threaded bar
decreases (the preload decreases and counterbalances a shorter
or lighter arm).
- Once adjustment is complete, tighten the counter-nut using the
fixed spanner.
!
It is strictly forbidden to adjust the spring so
that the force to overcome to stop it is greater
than 15 kg (150N)
MODIFYING THE BARRIER CLOSING DIRECTION
(RIGHT/LEFT)
NOTE, THE CORRECT DIRECTION OF THE BARRIER IS WHEN
THE MOTOR PISTON IS EXTENDED, THE BAR IS RAISED!
The barrier is supplied with the closing as requested (right/left) (as
seen from the barrier side).
If the direction of access is to be inverted, the barrier is fully
reversible and with simple operations, it is possible to readapt it,
following the instructions below.
- Disconnect power to the barrier, lock the switch with the key and
open the hatch (P) and the head cover (C).
- Lighten the load on the spring as explained in the chapter
“Adjusting the lifting force generated by the spring”, turn the
stainless steel stem until the threaded bar disappears.
- Remove the fasteners from the ends of the electrical piston
(threaded lock pin and pin).
-
Reposition the arm of the automatism on the other side, first
securing it at the base and then at the top, inserting the pin in the
eyelet, and reloading the spring preload.
- Adjust the spring as already described.
!
The spring still remains slightly preloaded. In
the extraction phase, pay attention to the
danger of crushing due to the unexpected
extension of the spring as highlighted by the
affixed adhesive.
