1 - Remove the springs, the
spring tensioners and the threa-
ded bars.

5.10 - Balancing

To balance the bar proceed as follows:
- disconnect the power supply and release the bar as described in
paragraph 5.3
- open the barrier door (Fig. 7)
- move the bar manually, keeping its opening angle at approximately
45°
- check that the balancing of the bar opened to an angle of 45° is en-
sured, i.e. the springs must be able to correctly balance the weight
of the bar (Fig. 17)
- if the bar balance is not ensured, bring the bar back to a vertical po-
sition and work the tensioners to increase or decrease the tension of
the springs until the bar reaches a stable balanced condition at 45°

3 - Screw in the new threaded
bars: the short bar 1 and the
long bar 3.
ATTENTION !
Stretch the springs progressively so that both can equally con-
tribute to balancing
- tighten the tensioner lock nuts to prevent them from becoming loo-
se during normal operation and lock the bar again
- restore the power supply and check that the automation system is
working properly
- Restore factory setting for 8 mt barrier
We recommend to check the correct balance every 6 months or
every 50,000 opening/closing cycles
