6) MANUAL AND EMERGENCY MANOEUVRES
In the event of a power cut or of abnormal operation, it is possible to release the bar and move it by hand (Fig. 6).
Using the key provided:
• To release the bar, turn the key in a clockwise direction until you fell a certain resistance.
• To restore the automatic movement of the bar, turn the key in an anti-clockwise direction until it is blocked.
7) BALANCING (FIG. 7)
For good operation of the barrier it is fundamental for the bar to be suitably balanced by the action of the spring. To check this, proceed as follows:
• Ensure that the spring is fixed to the correct point of the lever (see paragraph 2).
• Mechanically release the barrier using the release key.
• The correctly balanced bar must stay still in whichever point it is positioned:
- if it tends to open, decrease the tension of the spring
- if it tends to close, increase the tension of the spring
The tension of the spring may be regulated by manually screwing (anti-clockwise rotation) or unscrewing (clockwise rotation) the spring itself. Once
you have regulated the spring tension, block it, screwing down the nut “D” until it makes contact with the cap T.
8) REGULATING THE MECHANICAL STOPS (FIG.8)
The inertial movement of the bar after the motor stops is blocked using the adjustable mechanical stops shown in Fig.8.
After having regulated the opening/closing limit stop cam, bring the respective closing mechanical stop into contact with the lever. The opening mechani-
cal stop is of the damped type.
With reference to Fig.8:
• Slacken the blocking dowel
• Tighten /unscrew the mechanical stop until the desired position of intervention is obtained
• Tighten the blocking dowel
