As you select different points on the graph, the record number in the far left of the bottom
portion will change. A record represents one sample period of time. The actual counts
for this detector is listed next.
There are 16 possible alarms per detector. The first 8 alarms are based on the
Background Average, and the next 8 are based on the Truck Present Average. A ‘1’ in
any row in the Alarms box represents the level of alarm in that column.
The next box represents the photo-eye image from the photo-eyes. A ‘1’ in a column
represents that photo-eye being blocked, and a ‘0’ represents the photo-eye unblocked.
The leftmost digit is photo-eye number 1.
The last box lists the alarm number (1-8 and 11-18), the counts from the detector (and the
summed counts over time for alarms greater than 1 or 11), and the alarm point for each
alarm. Obviously, a count greater than its alarm point is an alarm condition.
