The installation of the VE.RAST interferes with the use of the SC.RES and vice

PREPARATION OF A RIGHT-HAND OR
LEFT-HAND ROAD BARRIER
If it is necessary to modify the opening direction of the road
barrier from right-hand to left-hand, or viceversa, proceed
as follows:
• totally unload the spring and unhook it from the anchoring
lever "L"
• remove the limit switch disc (fig.7 ref F)
• loosen the lock ring nut (fig.7 ref G)
• remove the spring anchoring lever (fig.7 ref L) and place
it opposite the previous position
• check alignment (fig.7 ref R) between the fitting plate "P"
and the anchoring lever "L"
• taking Fig. 8 as a reference, invert the position of the
mechanical stoppers "F1" and "F2". Loosen the cor-
responding lock grains before loosening the stoppers
(see paragraph ADJUSTENT OF MECHANICAL STOP-
PERS)
• hook the spring in the new position. Fig. 9 shows the
differences between a right-hand road barrier and a left-
hand one.
• in the control unit, invert the wires of motor, as well
as SWC limit switch (closing limit switch) and SWC-R
limit switch (closure braking limit switch).
EMERGENCY MANUAL OPERATION
Should a power failure occur or in the event of faults in the
system, the beam can be released and moved by hand:
• Introduce the customized key in the release lever and turn
it clockwise.
• Turn the release lever clockwise until the beam is released
and it can be opened and closed by hand.
• To reset the automatic operation, turn the lever anti-
clockwise until the beam is released. Reset the initial
position.

For a good operation of the road barrier, the beam must be
suitably balanced by the spring.
To check the correct balancing, proceed as follows.
• Check that the spring is correctly hooked to the lever (see
table 1).
• Mechanically release the road barrier through the release
key.
• The road beam, correctly balanced, should remain still in
any position:
- if it tends to open, reduce the spring tension
- if it tends to close, increase the spring tension
The spring tension can be adjusted by tightening (anti-
clockwise rotation) or loosening (clockwise rotation) the
spring by hand. Once the spring tension is adjusted, lock
it by moving the nut "D" in contact with cap T.
MOVEMENTS AND OPERATING TIME
During opening as per Fig. 11:
Starting from the closing position "C", the beam starts its
opening until it reaches the "SWO-R" point, where the ope-
ning limit switch triggers. The opening speed can be adjusted
through the control unit.
The beam moves for the remaining space (as shown in Fig.11)
at a reduced speed, for a time preset by the control unit.
Therefore, the barrier reaches point A, by completing the
opening movement.
During closure, as per Fig. 12:
The beam starts moving from the opening point "A" and stops
at "SWC-R " point, when the braking limit switch triggers. The
closing speed can be preset through the control unit.
After activation of the braking limit switch, the braking cycle
starts, ending only when the closing limit switch "C" trig-
gers.
The control unit checks the activation of the "SWC" limit
switch and it is able to automatically offset any changes due
to different weather conditions, for example.
The braking angle shown in Fig.12 is fixed at around 25°.
