MOUNTING THE "INDUSTRIAL"
After having cemented the base in the required position, as shown in Pic. 2, fix the mod.
INDUSTRIAL barrier in place by means of the supplied bolts, using a N° 27 setscrew wrench.
Now mount the boom arm. This must be carried out in four phases.
1 - Having removed the casing, insert the boom arm coupling links into the drive shaft and set
them in a horizontal position using the relative wrench.
2 - Assemble the two halves of the rod using the supplied nuts and bolts and a N° 8 setscrew
wrench (Pic. 3).
3 - Insert the boom arm into the boom arm coupling links (Pic. 4).
4 - Definitively fix the boom arm by tightening the four nuts on to the supplied bolts with a N°
17 setscrew wrench. Now apply the boom arm and plug.
The electric actuator is the irreversible type and needs no external locking system to maintain
an efficient closing position.

ELECTRICAL SAFETY DEVICES
The INDUSTRIAL limit switches and motor are already connected up to the electronic control
panel.
Only the wiring of a push-button panel, the flashing light and, naturally, the supply voltage
have to be connected up.
People and objects must be protected from crushing as a result of an inadvertent command,
so at least a pair of photoelectric cells or a sensor positioned below the barrier boom is
obligatory.
BOOM ARM BALANCING
When ordering the mod. INDUSTRIAL barrier, always specify the boom arm length in order to
obtain the correct number of counterweights.
LIMIT SWITCH SETTING
Normally the barrier is supplied to you with the limit switches already set to allow optimum
barrier movement.
If the base plate has not been cemented in on a level plane, the boom might be not perfectly
horizontal or vertical, with the result that the aesthetic appearance of the installation is poor.
To prevent this, the mechanical travel of the boom arm can be modified by means of the limit
switches, using two N° 9 wrenches.
Now adjust the electric limit switches by means of pawls "A" (Pic. 5) mounted on the disk,
using a N° 10 setscrew wrench to slacken the bolts that lock them on the same.
