Each day part and shift must have a start and end time. You can set the
definitions to any time periods that you want to track. Time definitions
must always have an earlier start time than end time.
1. DAY PART Time Definitions
• 8 day parts
• Start (mm:ss)
• End (mm:ss)
2. SHIFT Time Definitions
• 4 shifts
• Start (mm:ss)
• End (mm:ss)
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:
1. Enter the timer configuration menu, see above.
2. Select 6 Configure Timer > 1 Detection Type .
3. Change the value of the desired detector to Presence or
Pulse .
Threshold Minimum and Maximum
You can set the timer to ignore abnormally long or short events that
would skew average data.
Perform the following procedure to change the minimum or maximum
thresholds:
1. Enter the timer configuration menu, see above.
2. Select 6 Configure Timer > 2 Threshold MIN or 3
Threshold MAX .
3. Change the value of the desired detector to a new value:
• The range for minimum threshold is 0 to 9 seconds.
Any event that is shorter than the threshold is ignored
by the timer in averaging.
• The range for maximum threshold is 2 to 9 minutes.
Any event that is longer than the threshold is ignored by
the timer in averaging.
