4.1. Locking
The
locking mechanism (70)
is activated by an
electromagnet (71)
with positive security (locked under
voltage).
When the obstacle approaches its closed position, the
locking sensor (75)
is activated by detection of a
vane (76)
. The electromagnet then moves the lock 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)
.
The Fire Detection signal on the power board (see wiring diagrams) opens the obstacle in the selected
direction and allows free passage.
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 lock (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).
(*)
This option is not available on SL93x because the flow direction is not controlled
.
