Vehicle Detector And Loop Fault Diagnostics - HySecurity SwingSmart DC Series Programming And Operations Manual

VEHICLE DETECTOR AND LOOP FAULT DIAGNOSTICS

If HySecurity HY-5B 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 DC Controller senses a loop or detector problem:
z The LCD display flashes the name of the affected detector or error and the appropriate alert code.
z The buzzer chirps continuously at regular intervals until the issue is resolved.

Disconnected loop alert.
HY-5B vehicle detector -
Communications alert.
HY-5B vehicle detector -

Resolution
Alert indicates an unstable loop frequency. Check
loop and lead in wires for problems. Replace
them, if necessary.
Alert indicates that loop and lead in wires are
shorting out. Check wires for problems. Replace
them, if necessary.
Alert indicates loop wires are loose or
disconnected. Check wires for problems. Replace
them, if necessary.
Alert indicates detector is not communicating
properly with Smart DC Controller. Alert occurs if
detector is unplugged or connection is unstable.
If communication is not reestablished within
30 seconds, controller will reset and message
changes to ERROR 3.
Display indicates HY-5B detector malfunction.
Check detector for problems. Replace it, if
necessary.
Display indicates HY-5B detector malfunction.
It alert also works for any input connected to
terminal strip for standard box detectors. Check
that a vehicle is not parked on loop. Also,
determine if loop is stable. An unstable loop can
hold detector in a triggered state.
Alert indicates detector is not communicating
properly with Smart DC Controller. Alert occurs
if detector is unplugged or detector has failed.
To replace detector, press RESET button to clear
error and re-seat detector or install a new one.
