LIMIT SWITCHES REGULATIONS
It’s possible to adjust the limit switches
position, both the mechanical
(placed inside the barrier)
and electrical ones
(easily accessible,
as they are placed under the superior
cover).
N.B. When one of the mechanical end-
stroke switches is repositioned, it is
necessary to relocate the
electronically controlled one
accordingly, and then repeat the stroke
selecting procedure
