5) LEFT-RIGHT BARRIER (FIG. 3/4)

The EVA.7 normally is provided as right barrier (Fig. 3 A : EVA.7 RIGHT)
Conventionally it is considered right a barrier which seen from the side of the cabinet door, closes the passage by lowering the boom towards right.
However it is possible to reverse the barrier movement and turn a right barrier into a left one by means of few easy operations (Fig. 3 B : EVA.7 LEFT).
If the opening direction reversion is required, proceed as follows. If it is not necessary, go to the next section:
• totally unload the springs by loosening them and unhook them from the anchoring lever "L" (fig. 4)
• remove screws D1 and D2 and fix the extension rod A in the opposite position, on lever V.
• remove and fix the extension lever R in the opposite position.
• fix the springs onto the anchoring lever "L" .
• Fig. 4 shows the different positions of the components shows the differences between a right-hand road barrier and a left-hand one.
ATTENTION: AN INVERSION OF THE OPENING DIRECTION IMPLIES THE MODIFICATION OF THE POS MENU, AS DESCRIBED IN THE
PARAGRAPH "PROGRAMMING OF THE CONTROL UNIT".

6) EMERGENCY MANUAL OPERATION (FIG.5)

Should a power failure occur or in the event of faults in the system, the beam can be released and moved by hand:
• Introduce the customized key in the release lever and turn it clockwise.
• 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.

7) INSTALLATION OF THE OPTIONAL FOUNDATION PLATE VE.P650 (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 VE.P650 plate (ref. S). The brackets must be fitted to the foundation plate by means of 4 screws M12x50 (ref. V).
Check that the foundation plate is perfectly flat (ref. L), then fix the road barrier by means of nuts D and corresponding washers R.
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.

8) SELECTION OF BALANCING SPRINGS AND ACCESSORIES

Two types of springs can be selected, which are different in length: a short spring (364mm - EVA.KM) and a long one (480 mm - standard).
In Table , see the type of springs required according to the length of the beam and the use of accessories.
2 springs, 480mm long, which can be used in most types of installations, are factory supplied.
A 360mm long spring is not supplied with the system and it will be therefore necessary to buy it.
The table hereunder shows the indicative tensioning value (expressed in mm); for a correct balancing of the road beam, see section "Balancing".

* One or more of these accessories: SC.RES, VE.RAST, VE.AM.
** A 7 m long beam can be used only without accessories.

9) HOW TO FIX THE BEAM (FIG.7)

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.
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.
