10) BALANCING (FIG.8)
For a good operation of road barrier, the beam must be suitable balanced by the spring.
To check the correct balancing, proceed as follows. Mechanically release the road barrier through the release key.
• The road beam, correctly balanced at approx. 45°, 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.
• In table 1 of the "indicative tensioning" column, measures (expressed in millimeters) are shown. To obtain a tensioning value near to optimal, these
measures must be added to the spring length in rest position.
For example: In the event of a road beam 5.5m long, with installed accessories, the 364mm spring should be tensioned until a length of 416mm
(364+52), while the 480mm spring should be tensioned at a length of 618mm (480+138).
When two 480mm springs are used, the tensioning value of the two springs must be the same.
11) HOW TO ADJUST THE MECHANICAL STOPPERS (FIG.11)
After the motor stop, the inertial movement of the beam is blocked thanks to adjustable mechanical stoppers.
By taking Fig.11 as a reference:
• Loosen locking screws V1 and V2.
• Tighten/loosen the mechanical stoppers F1 and F2 until the desired activation position is obtained.
• Fix screws V1 and V2.
