• Turn the release lever anti-clockwise until the beam is released and it can be opened and closed by hand.
• To reset the automatic operation, turn the lever clockwise until the beam is released. Reset the initial position.
6) INSTALLATION OF THE OPTIONAL FOUNDATION PLATEVE.PS (FIG.6)
After preparing the cable laying (mains power supply, accessories, etc.), place the foundation plate keeping to dimensions indicated.
Brackets to be cemented are supplied with the system (ref. A). The brackets must be fitted to the foundation plate by means of nuts (B)
and corresponding washers C.
Check that the foundation plate is perfectly flat (ref. F), then fix the road barrier by means of nuts D and corresponding washers E.
Notes: the special shape of the slots on the bottom of the barrier cabinet, allow to adjust finely the position of the barrier.
It is suggested to leave 30 mm of threaded bar out from the foundation plate, a bigger length could generate an interference with the
spring, a smaller length does not ensure the proper fixing of the barrier.
7) POSITIONING OF THE SPRING AND ACCESSORIES (FIG.7)
According to the length of the beam and the type of accessories installed, before tensioning the spring, the correct point to hook the
spring to the lever must be selected.
The correct hooking point ("A", "B" and "C"), must be selected by taking account of table 1, according to the beam length and the type
of accessories to be installed.
8) HOW TO FIX THE BEAM (FIG.8)
Any accessories for the beam (protection edges, lights, pneumatic safety edges, rack, etc. ) are installed before fitting the beam. See
relevant instructions.
Fit the beam to plate P by using bracket S and both the 6 screws with the corresponding washers, and plate T.
Apply the removable plastic cover C.
9) BALANCING (FIG.10)
For a good functioning of the barrier it is necessary that the boom is balanced by means of the balancing 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.
10) HOW TO ADJUST THE MECHANICAL STOPPERS FIG.13
After the motor stop, the inertial movement of the beam is blocked thanks to adjustable mechanical stoppers.
By taking Fig.13as a reference:
• Release the barrier so that the boom can be operated manually.
• Loosen the lock grain G
• Tighten/loosen the mechanical stop until the desired activation position is reached
• Tighten the lock grain
Should an opening direction reversion is required, the position of the stoppers must be inverted.
• Tighten the fitting screw V of the cam.
