Description Access
Level
0 0 – 4
Number of Sites
Total number of loop sites
1 0 or
1 – 255
Maximum Presence Time
The time in minutes after which
continued loop activation
generates a vehicle presence
loop fault.
0 = disable the loop DFM
2 0 or
1 – 255
Maximum Absence Time
The time in hours after which
continued loop deactivation
generates a vehicle absence loop
fault.
0 = disable the loop DFM
3 0 or
1 – 32
Loop Pair Fault Detection
Threshold
The number of consecutive
vehicle detections counted on
either the upstream or the
downstream loop to cause a loop
pair fault to be generated.
0 = loop pair fault algorithm
disabled.
VCC -
4 0 or
1 - 32
Loop Pair Fault Clearance
Threshold
The number of (not necessarily
consecutive) vehicle detections
counted by both upstream and
downstream loops that must be
exceeded to cause a loop pair
fault clearance to be generated.
0 = loop pair fault algorithm
disabled.
