OFF
(by default, except for
BL4x)
The obstacle remains mechanically locked, thanks to the
position of the transmission elements between them.
Nevertheless, it is possible to unlock it manually using a
lever or a crank.
ON
(by default for BL4x
only, not adjustable)
The obstacle is unlocked: a pulse is given to take the
transmission elements out of alignment; opening may have
to be effected by hand.
This electrical opening is only available for equipment that
has a reversible motor reduction drive and a frequency
inverter (thanks to the capacities integrated into the control
board and the frequency inverter).
Note
: for BL4x AVR (with automatic opening of the arm in
case of power failure) subjected to great forces (strong winds
or fraud attempts to manually open the arm), the locking pin
might press against the locking clips and prevent the
automatic opening of the lock in case of power failure. This
parameter allows then to give the necessary reversed
impulse to release the lock.
For the BL4x SR (without automatic opening), this parameter
has no effect because the electromagnetic brake will block
the arm in position in any case.
Warning
: this adjustment is incompatible with the "Lock
Closed" command which has priority and will maintain the
obstacle closed.
Exploitation
Operating modes for the opening, closing and STOP
commands.
The commands follow this decreasing order of priority:
STOP (stop)
Lock OP (lock open)
Lock CL (lock close)
OP (open)
CL (close)
The presence sensors and reader inputs are at the same
hierarchical level as OP/STOP/CL => Lock Close has priority
in an opening loop and will work even if something is
detected.
Warning
: The OP command is never interrupted (the arm
always goes to the LSO before accepting the next command)
=> Lock Close will take affect after the obstacle has reached
its LSO.
Note
: Some use modes are incompatible with the operating
mode of the presence sensors (see the table of incompatible
modes, here after).
2 Contacts
(by default)
2 contacts used for opening and closing, on the control
board's connector block.
Open Cmd: open the obstacle
Close Cmd: close the obstacle on the rising edge of the
command.
STOP Cmd: stop.
Note
: A Lock Open command is given if the “No Passage”
timing has been activated, it will close when the following two
conditions have been met:
•
the Lock Open command is deactivated,
•
the set time has elapsed (or, immediately if there is a
detector on a closing sensor).
