5) PREPARING THE BARRIER FOR RIGHT OR LEFT (FIG.4)
If the opening direction reversion is required, proceed as follows. If it is not necessary, go to the next section:
• Entirely unload the spring by loosening it and unhooking it from the "L" anchoring lever
• with reference to Fig. 4, invert the position of the "F1" and "F2" mechanical stoppers. Before loosening the stoppers, back-off the related locking
grains (see section HOW TO ADJUST THE MECHANICAL STOPERS)
• unlock the geared motor (see "Manual Operation") insofar as to render the L hooking lever idle.
• according to the length of the road barrier arm and accessories used, choose the correct hooking position, as indicated in paragraph "Positioning of
the spring and accessories".
• hook the spring in the new position. Fig. 4 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).
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. 5).
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. 6)
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) MOVEMENTS AND WORK TIMES (FIG. 7)
During the closing manoeuvre:
The bar starts from point "A" and arrives at the point "C" of intervention of the slowing limit stop with a speed that may be set by the control unit.
The braking cycle starts from the intervention of the slowing limit stop and concludes exclusively with the intervention of the closing limit stop in point
"D", since the control unit checks when the limit stop "D" is reached and is able to compensate automatically any variations due, for example, to different
climatic conditions. The braking angle is fixed and corresponds to about 25°.
During the opening manoeuvre:
The bar starts from point "D" and arrives at the point "B" of intervention of the opening limit stop with a speed that may be set by the central control unit.
The bar covers the braking space when opening in a time defined by the control unit.
The bar then arrives at point A, completing the opening movement.
The regulations of the limit stop cams, of the trimmers and of the dip-switches must be carried out referring to these operating principles.
9) REGULATING THE LIMIT STOP CAMS
The regulation of the limit stop cams allows:
Cam A Anticipate or delay the start of the slowing phase in opening (Fig.7- point "B").
Cam C Regulate with precision the stopping point in closing (Fig.7 - point "D").
Note: Before activating the closing limit stop (Fig.8 - D), the cam C starts the slowing phase, activating the slowing limit stop (Fig.8 - C).
With reference to Fig.8:
• Slacken the cam fixing screw V.
• Bring the opening or closing cam into the desired position.
• Tighten the cam fixing screw V.
10) REGULATING THE MECHANICAL STOPS
The inertial movement of the bar after the motor stops is blocked using the adjustable mechanical stops shown in Fig.9.
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.9:
• Slacken the blocking dowel
• Tighten /unscrew the mechanical stop until the desired position of intervention is obtained
• Tighten the blocking dowel
