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.
