Spring Positioning; Shaft Fastening; Balancing; Configuration Parameters Of Shaft Movement - Beninca DIVA.3 Manual Del Usuario

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) SPRING POSITIONING

Based on the length of the shaft, before proceeding with spring tensioning, the correct coupling point must be chosen of the spring on the lever.
The correct coupling point, ("A", "B" and "C"), must be chosen in table 1 based on the length of the shaft.
The presence of a passive edge or the light diffuser does not influence the coupling point.

9) SHAFT FASTENING

Possible accessories for the shaft should be installed before fastening the shaft, consult the specific instructions.
Then, fasten the shaft to plate P using the shaft S and the 6 screws V1 with relevant washers R, also using the small plate T (Fig.8).
Apply the two gaskets G1 and G2
Apply the plastic cover casing C, using the 4 V2 screws.

10) BALANCING

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 (see Fig.9).
• 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.

11) CONFIGURATION PARAMETERS OF SHAFT MOVEMENT

The CP.DIVA control unit allows complete control of shaft movement.
During the opening phase (Fig.10):
On start-up of the opening manoeuvre, the shaft is brought to the standard manoeuvre speed, set by the parameter FSTO. The acceleration time is
adjusted by the TACC parameter.
The barrier opens at the standard speed when the point set in the TSMO parameter is met, therefore the deceleration phase begins as set in the TDEC
parameter that brings the shaft to execute the slowing phase set by the SLDO parameter. At the end of the SLDO phase, the barrier slows in opening.
During the closure phase (Fig.11):
On start-up of the closure manoeuvre, the shaft is brought to the standard manoeuvre speed, set by the parameter FSTC. The acceleration time is ad-
justed by the TACC parameter.
The barrier closes at the standard speed when the point set in the TSMC parameter is met, therefore the deceleration phase begins as set in the TDEC
parameter that brings the shaft to execute the slowing phase set by the SLDC parameter. At the end of the SLDC phase, the barrier slows in closure.
Note: for graphic representation needs, the TACC and TDEC phases have an important role in the manoeuvre, especially with low values, the TACC and
TDEC phases are not noticeable.

12) HOW TO ADJUST THE MECHANICAL STOPPERS

After the motor stop, the inertial movement of the beam is blocked thanks to adjustable mechanical stoppers. See Fig.12 as a reference:
• Release the barrier so that the boom can be operated manually
• Loosen the lock nut G
• Tighten/loosen the mechanical stop until the desired activation position is reached
• Tighten the lock nut.
