VEHICLE DETECTOR AND LOOP FAULT DIAGNOSTICS
Vehicle Detector and Loop Fault Diagnoscs
If HY5B vehicle detector modules are used, the SmartDC Controller has the ability to store and report
detector and loop fault informaon for performance diagnoscs.
If the SmartDC Controller senses a loop or detector problem:
• The LCD display ashes the name of the aected detector or error and the appropriate alert code.
• The buzzer chirps connuously at regular intervals unl the issue is resolved.
Table 13. HY5B Vehicle Loop Detector Faults and Errors
Alert or Error
# LCD Descripon Advisory Resoluon
ALERT 7 FREQ SHIFT FAULT HY5B vehicle detector –
Abnormal frequency change
alert.
The alert indicates an unstable loop
frequency. Check the loop and lead-in wires
for problems. Replace them, if necessary.
ALERT 8 LOOP SHORTED HY5B vehicle detector –
Loop is shorted.
The alert indicates that the loop and lead-
in wires are shorng out. Check the wires
for problems. Replace them, if necessary.
ALERT 9 LOOP OPEN HY5B vehicle detector -
Disconnected loop alert.
The alert indicates the loop wires are
loose or disconnected. Check the wires
for problems. Replace them, if necessary.
ALERT 10 I²C BUSS ERROR HY5B vehicle detector -
Communicaons alert.
The alert indicates the detector is not
communicang properly with the SmartDC
Controller. The alert occurs if the detector
is unplugged or the connecon is unstable.
If communicaon is not re-established
within 30 seconds, the controller will reset
and the message changes to ERROR 3.
ALERT 11 DETECTOR FAULT HY5B vehicle detector -
Malfuncon alert.
The display indicates the HY5B
detector malfuncon. Check detector
for problems. Replace it, if necessary.
ALERT 12 ON TOO LONG Detector input triggered too
long –
More than ve minutes.
The display indicates the HY5B detector
malfuncon. The 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.
