VEHICLE DETECTOR AND LOOP FAULT DIAGNOSTICS
Table 13. HY5B Vehicle Loop Detector Faults and Errors
Alert or Error
# LCD Descripon Advisory Resoluon
ERROR 3 DETECTOR FAILED HY5B vehicle detector -
Communicaon failed. The
SmartDC Controller will
behave as if the detector is
triggered, usually holding
the gate fully open.
The alert indicates the detector is
not communicang properly with the
SmartDC Controller. The alert occurs if
the detector is unplugged or the detector
has failed. To replace the detector, press
the RESET buon to clear the error and
re-seat the detector or install a new one.
Even if the loop problem self-heals, historical data about detector/loop performance and a log of
Alerts, Faults and Errors can be retrieved from the SmartDC Controller by downloading from the RS232
communicaons port or the USB port. HySecurity's free S.T.A.R.T. soware, a laptop computer, and a
special download cable or USB cable are required to retrieve and read this data.
Loop Health:
The HY5B monitors loop health which is comprised of loop noise, loop step changes and loop reference
changes. Loop health readings accumulate throughout a 24-hour period and the accrued readings are
posted to the Event Log each day at midnight. Aer midnight, the loop health baseline resets to its highest
value of 777.
Example of an HY5B Event Log posng:
Event log:
02/09 EVENT – CLD Loop Health: noise 5, step 6, ref 7.
Loop Presence:
Loop presence is dependent on “disturbance eect” of the enre vehicle. Presence determines how long
to hold the “memory” of a staonary vehicle on a loop before it is forgoen and ignored. Set the presence
of the loop:
LONG (default) lasts about 20 hours dependent on call strength and sensivity seng. The HY5B tunes out
the “disturbance eect” when a vehicle is staonary on a poron of the loop, but keeps the undisturbed
(unaected) poron of the loop operaonal.
INFINITE never drops the call. The INFINITE seng requires a certain amount of signal strength. A
“threshold” is maintained and it will hold the call forever. The loop connected to an HY5B with this seng
may become nonfunconing.
