Values Description
Operating modes for the opening, closing and STOP
commands.
The commands follow this decreasing order of priority:
STOP
Lock OP (lock open)
Lock CL (lock close)
OP
CL
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 2 contacts used for opening and closing, on the control
board's connector block.
(by default)
Open Cmd: open the obstacle
Close Cmd: close the obstacle on the rising edge of the
command.
STOP Cmd: stop.
Note: if a Lock Open command is given when the No
Passage timing has been activated, it will close when the
following two conditions have been met:
1 Contact Open Cmd: if active, the obstacle opens.
Open Cmd: if inactive, the obstacle closes.
STOP Cmd: stop. When the stop is released, the obstacle
will continue to open if an OP/Lock Open command is still
present, if not the obstacle will close.
Note: there is no CL contact in this mode.
Note: if this mode is used for a reader, it must be ensured
that the latter sends a continuous signal in order for the
obstacle to be kept open for a given time.
Note: this mode is highly recommended for barriers which
arm is Normally Open (tunnel entry, etc.). In this case
effectively, it is mandatory to maintain a continuous opening
command in order to prevent an untimely closing (by
maintenance personnel for example).
Warning: if there is a voltage loss while the obstacle is
open, the obstacle will close when the power comes back if
the OP command is not activated, because – in this mode –
an inactive open command equals a close command.
Step by Step Open Cmd: inversion at each rising edge (i.e., at each
pulse).
STOP Cmd: stop.
Note: neither CL nor reader commands are available in this
mode.
(stop)
(open)
(close)
 the Lock Open command is deactivated,
 the set time has elapsed (or, immediately if there is a
detection on a closing sensor).
