Adjusting The Limit Switches - RIB NORMAL Manual

NORMAL INSTALLATION
B
ASSEMBLING THE NORMAL BARRIER
After having cemented the fixing base in the position you prefer, fix the NORMAL unit, using
the nuts supplied and a setscrew wrench n. 19.
Then fit the boom following the four steps below.
1 - Turn the release crank until you reach the stop in order to fit the boom in the horizontal
position (springs shall be under tension).
2 - Insert the boom hub in the bush you have fitted in one of the holes on both sides of the
column and then lock it to the reduction gear with the screw TSPEI 10x90.
3 - Working from the ground, insert the U-plate on the boom with the four screws M8x110.
4 - Fix the boom by using a n. 13 wrench to tighten the four M8x110 bolts to the four nuts
and then apply the plugs to its ends.
Afterwards, substitute the hexagonal plug of the superior portion of the reduction gear unit with
the plug supplied to release the oil pressure, by using a setscrew wrench n. 24.

ADJUSTING THE LIMIT SWITCHES

The barrier is normally supplied to you with its electric limit switches already adjusted to allow
an Ideal movement of the boom.
If the base plate has not been cemented correctly on level, the boom may not be perfectly
vertical, therefore producing a poor aesthetic result for the system. In order to avoid this, you
can modify the vertical position of the boom adjusting the mechanical stopper screw with two
wrenches n. 17.
The electric limit switches can be adjusted, modifying the position of the pawls A mounted on
the disk. To do so, unloose the bolts that fix the pawls to the disk with a wrench n. 10.
ADJUSTING THE SAFETY CLUTCH
To adjust the safety clutch, use a ring nut wrench n. 30-32, release the ring nut E and tighten
the ring nut D clockwise, in order to increase the power transmitted by the motor to the boom.
Make sure the boom stops and slightly resists movement when it comes down. Block the ring
nut E again when you have finished the adjustment.
