Vehicle Detector and Loop Fault Diagnostics

If HySecurity HY-5A vehicle detector modules are used, the Smart DC Controller has the ability to store and
report detector and loop fault information for performance diagnostics.
If The Smart Touch Controller senses a loop or detector problem:
• The LCD display flashes the name of the affected detector or error and the appropriate alert code.
• The buzzer chirps continuously at regular intervals until the issue is resolved.

Reference
Resolution
The alert indicates an unstable loop
frequency. Check the loop and lead in wires
for problems. Replace them, if necessary.
The alert indicates that the loop and lead in
wires are shorting out. check the wires for
problems. Replace them, if necessary.
The alert indicates the loop wires are loose
or disconnected. Check the wires for
problems. Replace them, if necessary.
The alert indicates the detector is not
communicating properly with the Smart
DC Controller. The alert occurs if the
detector is unplugged or the connection is
unstable. If communication is not re-
established within 30 seconds, the controller
will reset and the message changes to
ERROR 3.
The display indicates the HY-5A detector
malfunction. Check detector for problems.
Replace it, if necessary.
The display indicates the HY-5A detector
malfunction. It alert also works for any
input connected to the terminal strip for
standard box detectors. Check that a vehicle
is not parked on the loop. Also, determine if
the loop is stable. An unstable loop can hold
the detector in a triggered state.
The alert indicates the detector is not
communicating properly with the Smart
DC 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.
