1. Fault phenomenon: The meter is energized without display and buzzing.
Possible cause: The fuse may be blown, or there is no input without 220V AC, and then the instrument transformer may have been broken by high voltage.
Solution: Replace the fuse, check if there is 220V AC input, check the transformer for burn marks, and replace the special transformer.
2. Fault phenomenon: The instrument is powered on and has a beep, but it is not normal.
Possible cause: It may be caused by unstable AC 220V power supply voltage, or the instrument CPU program is damaged.
Solution: After the 220V AC power supply is stable, the reboot is still not normal, and the CPU may need to be replaced if it is damaged.
3. Fault phenomenon: The meter shows a difference in angle.
Possible cause: The base of the scale body may be unrealistic, and the height of the sensor base is inconsistent after long-term use.
Solution: Re-adjust the angular difference or adjust the height of the base, as shown in the figure:
Nnecttype="rect" gradientshapeok="t" o:extrusio nok="f">
When adjusting, you can check the internal code of the sensor (see Chapter 4 of the manual). Generally speaking, the sum of the internal code values ​​of the six sensors is the weight of the weighing platform. The internal code value of the 1436 sensor should be basically the same, and the maximum difference cannot exceed Value="400" hasspace="False" negative="False" numbertype="1" tcsc="0">400kg, 25 is twice the number 14.
4. Fault phenomenon: The meter shows drift phenomenon.
Possible cause: The insulation performance may be weakened due to the long-term immersion of the digital sensor.
Solution: Prevent the sensor from immersing in water for a long time, and replace the same specification and address sensor. The inspection method is to check the internal code value of each sensor according to the fourth chapter of the manual to determine which sensor has drift.
5. Fault phenomenon: Err 01 is displayed during installation or use.
Possible cause: It may be that the digital sensor No. 01 is faulty or that there is a problem with its line connection or that the contact is poor.
Solution: Carefully check whether the sensor, junction box, and instrument connection are intact, and then look for sensor No. 01. If there is no sensor No. 01, it indicates that the sensor address has been changed. Use the instrument's modified address function (see Chapter 7) to number the sensor address. Change back to the original address number (the original address number is indicated on the certificate for each sensor). If the sensor No. 01 is found, measure whether there is 9-12V voltage between the red and black wires. If there is voltage, it can be judged that the sensor is damaged. It is necessary to replace the sensor with the same specification and address. If there is no voltage, the measuring instrument and Is the red and black connection on the DB9 plug of the junction box connected with 9-12V voltage? If there is any, the connection between the instrument and the junction box is broken. If there is no voltage, the internal power supply of the instrument is damaged and the instrument needs to be replaced.
6. How to judge if a sensor is faulty.
The instrument is turned off, plugged in the modified address plug, and then the meter is connected to the sensor to be determined (only one sensor can be connected).
After the power-on self-test, the number of the connected sensor is displayed. After pressing the input key, the meter displays the load of the sensor.
According to the meter display value, it can be visually judged whether the sensor is faulty. For details, see Chapter 7.
7, how to judge the instrument failure:
An alternate sensor can be directly connected to the meter, plug in the meter calibration head, press the “calibration†button during the power-on self-test of the meter, and directly enter the calibration state. Refer to Chapter 6 of the manual to set the number of sensors to 1, after exiting If the meter displays normal, the meter is not faulty, otherwise the meter will not be normal.
8. Fault phenomenon: The large screen display does not display normal weighing data from the boot.
Possible cause: The connection between the instrument interface and the large screen interface is not uniform.
Solution: Find some parts of the connection manual and the large-screen instructions about the connection interface, and properly connect the interface.
9. Fault phenomenon: The instrument will self-test after booting, and then display "........." crash.
Possible cause: The green and white data lines in the junction box are reversed.
Solution: The power should be disconnected immediately, and the meter should be used to check whether the corresponding color lines of all sensor cables and buses are correct, that is, red to black, black to black, white to white, green to green, and test whether there is any collision between them. Line, you can reconnect.
10. Fault phenomenon: After the meter and computer are connected, the weighing software is run without weighing digital display.
Possible cause: The data cable connected to the instrument and the computer is not connected correctly or the baud rate setting is not uniform.
Solution: Find some parts of the instrument manual and the large-screen instructions about the instrument and computer connection interface, connect the interface correctly, and then check the meter and computer software baud rate settings.
11. Fault phenomenon: After the meter and computer are connected, the running weighing software displays garbled characters.
Possible cause: The baud rate setting of the meter and weighing software is not uniform.
Solution: Check the baud rate set in the meter and computer weighing software separately, and set the settings uniformly.
12, failure phenomenon: After the car is called the platform, the instrument still shows a relatively large stable data.
Possible cause: The limit of the weighing platform is stuck.
Solution: Check the limit of the weighing platform and adjust it to a reasonable position.
13. Fault phenomenon: The boot displays an “Err†error message, and the meter checks each sensor under the modified address state, and the sensor can work normally. Starting from "No. 1", the number of connected sensors is gradually increased. When a certain number of sensors are connected, the instrument will display an "Err" error message.
Possible cause: The meter has insufficient power for the load.
Solution: Replace the meter.
14, fault phenomenon: the instrument has been showing relatively large data after booting, and a large range of flicker.
Possible cause: The voltage is unstable or there is external interference.
Solution: Increase the regulated power supply, the power supply requires a ground wire. If the meter is a metal case, measure the case voltage to see if it is normal and ground the case.
15, fault phenomenon: instrument display FFFF
Possible cause: weighing overload
Solution: remove the overloaded part of the goods and then weighed
