4.1. Locking
The
locking mechanism (70)
is activated by an
electromagnet (71)
with positive security
(locked under voltage).
When the obstacle reaches its closed position, the
locking sensor (75)
is activated by
detection of a
vane (76)
. The electromagnet then moves the bolt into hole (77a) of
plate (77)
,
locking the rotor (12). Locking is maintained by the electrical circuit between the
hold magnet
(72)
and the
contact plate (73)
.
NON-RETURN OPTION (for TBV model only)
: During the opening in one direction, if the
obstacle is forced to open in the other direction, the electromagnet (68) moves the non-return
bolt (69) into hole (77b) of plate (77) , locking the rotor (12).
The correct movement continues as soon as this reverse force is removed (without putting the
equipment out of service).
