TYPE A LIMIT SWITCH (16)
For installation on the rack, refer to picture 18 and proceed as follows:
Position the magnet holding brackets
A3(16)
on the rack
A5(16)
at the two ends of the gate
A4(16)
in the gate closed
and gate open position. With reference to the sensor
A1(16)
positioned on the board, fit the magnets
A2(16)
on the
brackets
A3(16)
in horizontal position
(18)
in correspondence to
A1(16)
.
N.B.:The magnets must be at least 9 mm from the gearmotor casing (16).
NOTE:
The limit switch marked
"SX"
must be secured in correspondence to the gate-open position and the one
marked
"DX"
in the gate-closed position
(20 - 21)
.
To ensure this condition in applications where the motor is
installed on the "left" (20) invert the motor power cables.
Note with reference to Figure 20

TYPE B LIMIT SWITCH (17)
For installation on the rack, refer to picture (19) and proceed as follows:
1- insert the nuts
B17(19)
in the hexagonal seats on the magnet holder
B10(19)
;
2- insert the grub screw and nut
B11(19)
in the magnet holder
B10(19)
making sure that it protrudes towards the
rack
B12(19)
by at least 1-1.5 mm;
3- insert the adjusting screw and nut
B16(19)
in the hexagonal seat of the magnet holder
B10(19)
;
4- assemble the bracket
B13(19)
using the screws provided
B14(19)
and insert the grub screws
B15(19)
.
6- continue fitting the rack, aligning the modules one after another; to properly secure the modules, use a piece of
rack of about 150 mm to allow for tooth timing
(14)
. Once the last module has been secured, cut off the
protruding part with a saw.
7- when all the modules have been fitted, manually carry out various gate opening and closing manoeuvres to
check that it slides smoothly without friction;
8- lower the operator by turning the 4 adjusting screws
A(8)
and lock the gearmotor leaving a clearance of 2 mm
between the pinion and the rack
(15)
to ensure that the weight of the gate does not negatively affect the gearmotor
shaft.
Each automated device kit for sliding gates contains two sets of limit switches: one to identify the stopping point of the
gate during opening and closing, and one to identify the starting point of the deceleration phase during opening and
closing.
For the TYPE A limit switches, the opening limit switch is identified by the symbol SX and the closing limit switch by
the symbol DX.
For the TYPE B limit switches, each limit switch is supplied with the magnet already fitted, identified by the letter "O"
for opening and "C" for closing.
