Troubleshooting Guide

In the worse environment where the interference is very strong, the device cannot be installed. We can provide a special customized
motherboard to complete this project!
6. Common Malfunction Analysis
No.
Conclusion
Fault Phenomenon
Analysis and Solution
1
Hardware Malfunction
System not start
Check whether the fuse is burn and the power voltage is 110v or 220v, change the
power supply unit
2
Hardware Malfunction
No transmitter signal
Listen carefully to check whether the transmitting antenna has a soft vibration
when transmitting, or use an inductive electric pen to test whether there is an
electromagnetic field around the antenna. If not, it may be a malfunction of the
transmitting motherboard. Change the master board.
3
Hardware Malfunction
No alarm: no alarm even if the label is placed very close
(label should be good and tested on other system)
See if the indicator light is under normal work or not, check if the connection cables
include 9pin cable, 5pin cable, and network cable are firmly connected. Fix each
connection socket.
4
Hardware Malfunction
Red light Indicator
Factory Reset
5
Power Problem
The noise value is too high, the sensitivity is low, and
there are occasional false alarms.
Check if the power supply connect the ground wire
6
Power Problem
Two channels use the same power supply, one channel
High sensitivity, but low sensitivity in other channel
Check if the position of the neutral line and the fire line are opposite. Change the
power connection, or set in our software @ Slope: Rising to Falling in parameter
settings
7
No Detect Tags
Observe the indicator light on master board, the lower row
of indicators is fully illuminated
Check if there are tags nearby, move the soft label 1.5 meter away, move the large
tags 2.0 meter away
8
False Alarm
There are large metal objects around the antenna (such as
metal shopping carts, lockers, umbrella racks, etc.). Metal
objects close to the antenna cause distortion of the
detection signal, increase the noise value, reduce the
detection distance, and cause interference to the antenna.
Remove large metal objects until false positives are eliminated
9
False Alarm
There are a lot of spotlights and fluorescent lamps near the
antenna. and false alarm when turned on
The starter of spotlights and fluorescent lamps is close to 58KHZ, which interferes with
the antenna. Replace the starter for spotlights and fluorescent lamps
10
False Alarm
There are asynchronous magnetic and magnetic devices
around the antenna. When it is out of sync with other
aeromagnetic devices, system false alarms are easy to
occur.
Increase sensitivity and synchronize by software debugging
11
False Alarm
Soft labels or hard labels are too close to the antenna.
When the label on the checkout counter or clothing store
closet is too close to the antenna, a system false alarm will
occur.
The additive effect of the tag signal, moving the tag to a greater distance
