POSITIONING THE MECHANICAL LIMIT SWITCH
The mechanical limit switch must be adjusted so that both during opening
and closing it stops the carriage run before the mobile leaf hits any other
component.
It is also used by the electronic control unit to get the leaf limit points.
When adjusting the opening mechanical limit switch, take into account that
except for the set-up manoeuvre and for the first manoeuvre after a power
failure, at the end of the opening the mobile leaf stops about 5 mm before
coming into contact with the limit switch.
To adjust the limit switch, loosen the 2 fastening screws, move the limit switch
to the desired position, then fully tighten the 2 screws again.

ANCHORING THE LEAVES TO THE CARRIAGES AND ADJUSTING THEM
!
Unscrew the two front screws "A" of every carriage and remove the movable part "C"
!
Secure the disassembled mobile part “C” on the door at the distance shown in the figures from 9 to 12 depending on the type
of automation.
!
Now hang the leaf to the automation, matching the two carriage parts, then screw the "A" screws into their seats without
tightening them.
!
Adjust the height of the leaf by means of the control screw "B" and fully tighten the two "A" screws.
!
Adjust the leaf horizontally by means of the eyelets "E" provided in the movable part of the carriage.
!
To ensure the correct operation of the automated equipment, it is important that the mobile leaf is perpendicular to the
transom.
!
Adjust the height of the retaining runner operating the adjustment screw (D) so that the runner touches the top inner profile of
the transom without applying pressure.
!
Then manually move the leaf and check that there are no frictions at any point, otherwise adjust again the retaining runner.
