VEHICLE DETECTOR AND LOOP FAULT DIAGNOSTICS
Table 13. HY5B Vehicle Loop Detector Faults and Errors
Alert or Error
# LCD Description Advisory Resolution
ERROR 3 DETECTOR FAILED HY5B vehicle detector -
Communication 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 communicating 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 button 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
communications port or the USB port. HySecurity's free S.T.A.R.T. software, 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. After midnight, the loop health baseline resets to its highest
value of 777.
Example of an HY5B Event Log posting:
Event log:
02/09 EVENT – CLD Loop Health: noise 5, step 6, ref 7.
Loop Presence:
Loop presence is dependent on “disturbance effect” of the entire vehicle. Presence determines how long
to hold the “memory” of a stationary vehicle on a loop before it is forgotten and ignored. Set the presence
of the loop:
LONG (default) lasts about 20 hours dependent on call strength and sensitivity setting. The HY5B tunes out
the “disturbance effect” when a vehicle is stationary on a portion of the loop, but keeps the undisturbed
(unaffected) portion of the loop operational.
INFINITE never drops the call. The INFINITE setting 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 setting
may become nonfunctioning.
