4.2.3.4.
Locking of the card reader
The card reader receives a piece of information which locks it in some circumstances.
The contacts between exits
X13.9 and X13.10 (X13.19 and X13.20)
are activated in direction A
(B) in order to inform that the PNG is occupied. A jumper allows use of an NO or NF contact.
The reader is locked in direction A (B) in the following situations:
1.
Evacuation
mode
2.
Free
mode direction A (B)
3.
Locked
mode direction A (B)
4.
Passage in progress direction B (A) in
free
or
controlled
mode
5.
Passage in progress direction A (B) without reader storage
6.
Opposite direction
fraud
7.
According to the initialization, intrusion (pre-alarm) direction A (B)
Note:
The reader is not locked in the event of "tailgating" fraud so that the user does
not have to walk back to present his ticket.
4.2.4.
Safety on obstacle closing
During the door closing movement, if the closing
limit switch is not reached before the end of the time-out
%TM10 (4 sec by default), the obstacles will reopen during a time-out %TM11 (2 sec by default) and then
close again.
This sequence is permanently activated if the closing limit switch is never reached.
4.2.5.
Safety on obstacle opening
If there is a presence in the safety zone when the doors are closed and they have to reopen, they will
remain closed while the safety zone is not free.
Once the safety zone has been freed, the doors will open if opening command is still active and after a
short time-out (%TM13) (0.3 sec by default).
4.2.6.
Safety zone
The safety zone always consists of the CS cell, placed between mobile glass and
safety bands
installed
on fixed glass. These bands consist of transmitter and receiver cells. This is an optional equipment.
Warning
: If the safety bands are not installed on the PNG fixed glass, entrances X13.15 and
X13.16 must be shunted.
It is possible to add other cells to the safety zone during the PNG configuration procedure: C6, C7, C13
and/or C14 (DIP2 to DIP5 of word 2)
If the doors are open, any presence in this safety zone will keep the doors open.
If the doors are closed, any presence in this safety zone will prevent the doors from opening.
4.2.7.
Variable speed controller management
The opening command is transmitted by the PLC to the variable speed controller through a binary variable.
The activation level for this variable may be selected during the configuration procedure:
- DIP 1 of word 3 = 0:
if the variable is activated at 1, the variable speed controller will receive an opening command
- DIP1 of word 3 = 1:
if the variable is activated at 1, the variable speed controller will receive a closing command.
The choice of this DIP’s position is depending on the type of the variable speed what is installed in the
PNG and on his activation mode. The appropriate position of the DIP is fixed by the factory.
