Detection of passage through doors
The programme follows the progression of the user in direction A in front of the successive cells
C4, C5 and C6 (corridor A). Once cell C6 has been freed, passage detection is activated at the
condition that several cells before the obstacle are free (by default : 3 cells : C4, C5 and C6).
The programme follows the progression of the user in direction B in front of the successive cells
C9, C8 and C7 (corridor B). Once cell C7 has been freed, passage detection is activated at the
condition that several cells before the obstacle are free (by default : 3 cells : C7, C8 and C9).
Passage detection through the doors validates the passage, deactivates the passage
authorization and/or decreases the number of authorizations stored. This will result in the
closure of the doors (in NF mode)
The number of cells which must be free before the door in order to validate detection may be
modified via the parameter %MW29:
- %MW29 = 3 (default): this mode avoids deductions and false closures of obstacles but is
suitable for average flows
- %MW29 = 2: this mode is appropriate for better deductions in the event of large flows.
4.2.3.3.
Passage contact
Each time a passage is detected in direction A (B), in all operation modes, a 700 ms impulse is
generated by contact between terminals
X13.7 and X13.8 (X13.17 and X13.18).
The passage contact may be given at two different times following the value of the parameter
%M34:
%M34 = 0 (by default):
the passage contact is given when the entry zone is exited in the
direction of passage. This method maximizes passage flow.
%M34 = 1:
the passage contact is given when the person has passed in the correct direction
and has completely left the PNG, and when the obstacles have been closed. In this event,
authorization storage is not possible as the obstacles have to close after each person.
This method slows down the flow but maximizes control.
