How the threshold works when using digital inputs
NOTE:
Refer to ‘ Notes about the Digital I/O interface ’ on page 69 for further information about the digital
inputs.
When the counting process is disabled (i.e. when the door is closed), people remaining anywhere in the detection
area will be counted as IN, and the counter will be amended accordingly.
When the counting process is enabled (when the door is open), every person already within the door threshold
line and the portion of detection area facing the door, will be counted as OUT if they leave the detection area;
again, the counter will be amended accordingly.
WARNING!
The commutation time of digital inputs is extremely important because any propagation delay in the
signal may affect severely the precision of the counting.
The digital inputs should enable the PCN-1001 as soon as the door starts opening and should
disable it after the door is closed completely.
