1. Check if the power supply is working properly
When you find that the system is not working properly, you should check
whether the system power is normal or not:
 Whether the working indicator on the device is blinking;
 Whether the input power voltage is correct;
 Whether the power wiring is open or short;
 Whether the power socket is firmly connected; whether the input voltage
fluctuates too much.
2．System detection sensitivity is reduced
In general, most of the faults that cause the detection sensitivity of the system
to decrease are caused by mutual interference and suppression between the systems,
and interference caused by metal objects or electrical equipment near the detection
antenna. Take measures to remove metal objects and electrical equipment near the
device, and keep them away from the equipment as far as possible. For the test
method, see section 5.6.6 Noise Detection. If you cannot get the device away from
the interference source, you need to put a magnetic ring on the interference source
until the device works normally.
3. Not able to search out all gates
Check that all gates are wired correctly and the input and output terminals are
reversed.
4. The system does not alarm
When detecting the label, if the alarm light is not flashing or there is no alarm
sound, the following operations can be performed for troubleshooting:
 Check if the antenna wiring port is loose or detached.
 Check whether the alarm light and buzzer are well connected and whether
the alarm light and buzzer are damaged. Acousto-optic alarm detection
can be carried out for the non-alarm gate separately. For the test method,
see section 5.6.9 Acousto-optic Alarm.
