Automatic
Sensitivity
Boost
The Automatic Sensitivity Boost causes the sensitivity
to increase following initial detection. This feature is useful
to prevent dropout when detecting high-bed vehicles.
The sensitivity returns to its normal setting after the vehicle
exits the loop. The decimal point on the ULTRAMETER™ display
indicates ASB is on.
Infinite presence mode causes the output to remain in detect
as long as the vehicle remains on the loop. Normal presence
mode causes the output to reset after 5 minutes. Do not use
Normal presence mode for reversing loop applications.
The Detect-On-Stop™ (DOS
®
) feature requires that a vehicle
must come to a complete stop over the loop for a minimum of
1-2 seconds before Output B activates. DOS
®
will not function
if in Loop Fault mode. Do not use DOS
®
feature for reversing
loop applications.
Output B is configurable for four possible modes.
In Pulse on Entry/Exit mode, Output B will be activated for
approximately 500ms when a vehicle is entering or exiting
the detection zone. In B same as A, relay B has the same
output as relay A. In Loop Fault mode, the relay will trigger
if a loop fault occurs.
The Fail Safe setting causes the ULT-PLG to activate the
presence output in the event of a loop failure. The Fail Secure
setting will cause the ULT-PLG not to activate the presence
output in the event of a loop failure. Do not use Fail Secure
for reversing loop applications.
DIP switches 2 and 1 are used to assign the loop operation
frequency. The primary purpose of the Frequency Setting
is to allow the installer the ability to set different operating
frequencies for multi-loop installations and is recommended
to prevent crosstalk/interference from multiple loops.
