Detector & Loop Fault Diagnostics
If HySecurity HY-5A mini detector modules are used, the Smart Touch Controller has 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 will flash the abbreviation for the affected detector (ELd – ioLd – ooLd – SLd)
then it will flash the appropriate Alert Code (ALE_) to disclose the nature of the problem and the buzzer will
chirp.
Loop detector freq change alert ALE7 2 chirps/sec every 15 seconds
Loop shorted or open alert ALE8 2 chirps/sec every 15 seconds
Loop detector failed alert ALE9 2 chirps/sec every 15 seconds
Loop detector active >5 minutes AL12 2 chirps/sec every 15 seconds
Loop detector comm. alert AL10 2 chirps/sec every 15 seconds
Loop detector function alert AL11 2 chirps/sec every 15 seconds
Loop detector failed Err3 3 chirps/sec once per minute
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 Smart Touch Controller by downloading from the RS232 communications
port. Optional HySecurity “START” software, a PC computer, and a special download cable are required to
retrieve and read this data (see bottom of page 29).
Frequency:
Knowing the exact frequency of a loop can be useful as a diagnostic tool, and verifying that the loop frequency
is stable is also very valuable information. To view the actual loop frequency of a specific vehicle detector, go
to the setting for that detector, then switch the selection to 1 and press the menu button. The display will flash
between [F_xx] which are the high digits, then the low digits of the loop frequency counter. For example: [F_05]
+ [3413] would represent a frequency of 53,413 Hertz. The highest digit will probably be only a single digit
because loop frequency is usually a five-digit number, between 20,000 to 80,000 Hertz.
Changing the Loop Frequency:
HY-5A detectors can never crosstalk. If for any reason, you want to manually change the loop frequency,
change the menu selection to a flashing 4 and then press the Select button. Each detector has a choice of four
frequencies. To exit, press the Menu button and the controller will perform a reset and tune to the new
frequency setting.
Call Strength Level:
Knowing the strength level of a detector call is valuable because it provides information about how well the loop
is actually “seeing” a specific vehicle. For example, it may be useful to check to see if the loop is easily
detecting the middle of a high bed semi-truck. The strength of a detector call can be displayed in real time, on a
scale of 1-7. As indicated in the table below, when a detector’s menu setting is set to 2, and the menu button is
pressed, the LCD display will read [LE_x]. If the call strength is level 4 or less, consider increasing the
sensitivity level, by adjusting the rotary switch on the HY-5A detector.
