5 - PRODUCT INSTALLATION

5.1 - Installation

ATTENTION !
The installer must ensure that the temperature range shown on
the automation device is suitable for its required installation
position.
Before proceeding with the installation, check the integrity of the pro-
duct and ensure that all the components are in the package.
1. Provide a foundation of adequate dimensions for the fixing plate
of the barrier to be installed (Fig. 4) and prepare one or more tubes
for the routing of electric cables (Fig. 5a).
2. Assemble the anchoring clamps on the anchor plate and fix them
using the 4 bolts supplied.
3. Cast concrete in the foundation trench and position the foundation
plate.
ATTENTION !
Check that the plate is perfectly level and parallel to the opening.

5.2 - Reversal of opening direction

The automation systems for ALT road barriers are factory-set for bar
mounting facing right - looking at the barrier frontally with respect to
the door (Fig. 6a).
If it is necessary to install the bar on the other side, i.e. on the left, like
in figure 6b, carry out the operations indicated below
VERSION ALT3KF
- Open the door, loosen the spring tensioning system and then rele-
ase the springs from the tightening eyelets of the tensioners (Fig. 7
and 8)
- Unscrewing the upper screw, remove the connecting rod between
the motor lever and the balancing lever (Fig. 9)
- Remove the two fixing screws of the articulated joint heads of the
tensioners (Fig. 10)
- Rotate the balancing lever on the opposite side, all the way to the
limit stop (Fig. 11)
- After carrying out this manual manoeuvre (see the procedure for un-
locking the bar, Par. 5.3) rotate the motor lever on the opposite side
and connect the connecting rod to the balancing lever again (Fig. 12),
then restore the transmission drive.
- Screw back in the two fixing screws of the articulated joint he-
ads of the tensioners (Fig. 12) in the positions indicated in Par. 5.6
(ALT324KF Accessories and bar weight balancing) determined ac-
cording to the length of the bar
- Hook up the springs to the tensioner fixing eyelets and, turning by a
few turns, partially restore the tension of the springs (Fig. 13)
- Install the bar in a vertical position and proceed with balancing (next
Par. 5.10), (Fig. 14)
VERSION ALT4K
- Open the door, loosen the spring tensioning system and then relea-
se the spring from the tightening eyelet of the tensioner (Fig. 7 and 8)
- Remove the fixing screw of the top articulated joint head of the
tensioner (Fig. 10)
- After carrying out this manual manoeuvre (see the procedure for
unlocking the bar, Par. 5.3) rotate the balancing lever on the opposite
side (Fig. 11), all the way to the limit stop, and restore the transmis-
sion drive
- Re-tighten the fixing screw of the articulated joint head of the tensio-
34
4. Wait for the concrete to set completely.
5. Unscrew the 4 nuts that keep the base fixed to the clamps and
position the cabinet on the plate (Fig. 5b).
ATTENTION !
It is advisable to install the cabinet with the inspection door fa-
cing the most easily accessible side.
ATTENTION !
Never take down the bar for any reason until it is in a horizon-
tal position and never perform an emergency or manual mano-
euvre if the bar is not installed.
ATTENTION !
The barrier must be equipped with mechanical stops for ope-
ning and closing that prevent the barrier over-travel.
ATTENTION !
On ALT624K, before mounting the boom, make sure that the
countersunk screw that secures the support plate of the boom
is fully tightened (Fig. 14).
ner (Fig. 12) in the position indicated in Par. 5.7 (ALT424K Accesso-
ries and bar weight balancing) determined according to the length of
the bar and of the installed accessories
- Hook up the spring to the tensioner fixing eyelet and, turning by a
few turns, partially restore the tension of the spring (Fig. 13)
- Install the bar in a vertical position (Fig. 14) and proceed with balan-
cing (following Par. 5.10)
VERSION ALT6K
- Open the door, loosen the spring tensioning system and then rele-
ase the springs from the tightening eyelets of the tensioners (Fig. 7
and 8)
- Unscrewing the upper screw, remove the connecting rod between
the motor lever and the balancing lever (Fig. 9)
- Remove the two fixing screws of the articulated joint heads of the
tensioners (Fig 10)
- Rotate the balancing lever on the opposite side, all the way to the
limit stop (Fig. 11)
- After carrying out this manual manoeuvre (see the procedure for un-
locking the bar, Par. 5.3) rotate the motor lever on the opposite side
and connect the connecting rod to the balancing lever again (Fig. 12),
then restore the transmission drive
- Screw back in the two fixing screws of the articulated joint heads of
the tensioners (Fig. 12) in the positions indicated in Par. 5.8 (ALT624K
Accessories and bar weight balancing) determined according to the
length of the bar and of the installed accessories
- Hook up the springs to the tensioner fixing eyelets and, turning by a
few turns, partially restore the tension of the springs (Fig. 13)
- Disassemble the rod support plate (Fig. 14) and reassemble it by
orienting it upwards. Insert it fully onto the square shaft, possibly with
the help of a rubber hammer, lock it firmly in place with the toothed
conical washer and fully tighten the countersunk screw
- Install the bar in a vertical position and proceed with balancing (next
Par. 5.10), (Fig. 14)
