Fixing of the limit switch bracket on versions
with inductive limit switch
The limit switch bracket must be fixed as described below for the
RB250 and RB500 versions that utilise the inductive limit switch.
1.
Manually place the leaf in the open position leaving at least
2-3 cm from the mechanical stop.
2.
Slide the bracket along the rack in the opening direction until the
corresponding LED switches off, as in fig. 13. Then bring the brack-
et forward by at least 2 cm and secure it to the rack with the appro-
priate dowels.

Manually place the leaf in the closed position leaving at least 2-3 cm
from the mechanical stop
4.
Slide the bracket along the rack in the closing direction until the cor-
responding LED switches off. Then bring the bracket forward by at
least 2 cm and secure it to the rack with the appropriate dowels.
The ideal distance of the bracket for inductive limit switches
is between 3 and 8 mm as indicated in fig. 14.
!
In order to prevent the weight of the leaf from affecting the
gearmotor, it is important that there is a play of 1÷2 mm between
the rack and the pinion as shown in Figure 10.
8.
Slide the leaf, using the pinion as a reference point for the fastening the
other elements of the rack.
9.
Cut away the exceeding part of the rack.
10.
Open and close the gate several times and make sure that the rack is
aligned with the pinion with a maximum tolerance of 5 mm. Moreover,
check that the play of 1÷2 mm has been respected along the entire
length between the pinion and the rack.
11.
Thoroughly tighten the two fixing nuts of the gearmotor making sure it
is well fastened to the ground. Cover the fixing nuts with the relative
caps as shown in figure 11.

the limit switch bracket on versions with inductive limit switch”):
• Manually place the leaf in the open position leaving at least 2-3 cm
from the mechanical stop.
• Slide the bracket along the rack in the opening direction until the lim-
