Note:
Time definitions must always have an earlier Start Time than End Time. If the End Time is a value smaller
than Start Time, it is assumed to occur the next day. Ex. Start = 6:00, End = 2:00 means Start 6:00 am,
End time 2:00 in the morning the following day.
Detection Type
Because each vehicle detector can be a presence type or pulse type detector,
you must ensure that the timer is configured for the correct type.
Note:
The default detector type is presence. If you do not have any pulse type detectors you should not need to
change these settings.
Perform the following procedure to change the detector type:
