Chapter 11: Malfunction & Troubleshooting
1.
Malfunction description: No display and no buzz after power on.
Possible Reason: Maybe the fuse is broken, or no power source, or the transformer
inside crashes because of high voltage.
Solution: Change a new fuse, check the electricity, or check the transformer.
2.
Malfunction description: Abnormal display and buzz.
Possible Reason: Maybe the electricity is not stable, or CPU is broken.
Solution: re-boot after the voltage is stable, if the situation is the same maybe the CPU
has to be changed.
3.
Malfunction description: it shows there are different corners.
Possible Reason: Maybe the base of the balance is not so solid, and sensors are not on
the same level after a long time.
Solution: Re-adjust the different corners or adjust the height of the sensor base.

Adjust the balance according to inner code of sensors (see section 4). Generally
speaking, the sum of all the numbers is the weight. Inner code of
①④③⑥
are
basically the same, the difference can be no more than 400kg, the value of
②⑤
are as
twice as
①④
.
4.
Malfunction description: it shows that there is data floating.
Possible Reason: maybe sensors are affected with damp; the function of insulating
becomes weaker.
Solution: Protect sensors from constant water effect. Replace the sensor with the same
specification and address. Find detailed instruction in section 4, checking the inner
code of each sensor can help to find the right one which causes data floating.
5.
Malfunction description: it displays Err 01 while installing or working.
Possible Reason: maybe No. 1 sensor is broken or the connection is too poor.
Solution: check the connection among sensors, junction box and indicator. Search for
No. 1 sensor, if no NO. 1 sensor is found, that means the address is modified. Set the
address back to the original setup via the indicator according to the eligibility mark
(see section 7). If No.1 sensor is found, please test the voltage between the red wire
and black wire. If there is a 9-12V voltage, it is concluded that the sensor is broken;
replace the broken one. If there is no voltage, test the voltage between the red wire and
the black wire on the DB9 plug that is used to connect the indicator and junction box.
If there is a 9-12V voltage, the connecting wire is broken. Otherwise the indicator is
broken.
