Truck scale in the use of the process there will be some failure, then the truck scale in the event of failure should we how to deal with? Xiaobian find several common truck scale failure and maintenance methods to share with you.

1, the instrument does not return to zero

Phenomenon: there is a truck scale, empty scale, the instrument does not return to zero. After zero, after a heavy car, car under the scale, the instrument’s indication is still not back to zero.

First check the gap around the scale body whether there is foreign body stuck, both sides of the scale body and the seams are there are deposits (such as truck scale weighing concrete, coal and other easy to throw the material users often appear this situation); After the cause of the instrument to perform a zero calibration. If the problem still exists, you have to check the instrument behind the nine-pin plug, if there is loose or oxidative rust corrosion, first with a simple brush cleaning, and then tighten the plug. If there is still a problem, check the cable lines, especially the lines.

2, small load normal, large load smaller

Phenomenon: There is a truck scale, all the normal self-test, empty scale display value is zero, when the weighing load hours the instrument shows normal, and on the large load, the instrument display value is smaller than the actual value.

First of all to check the electronic truck scale body at the bottom of whether there is a foreign body to withstand the scale body. This phenomenon, indicating the possibility of damage to the instrument or sensor is very small, usually the electronic truck scale scale body at the bottom of a foreign body to withstand the scale body, because in the small load, the scale body contact with foreign body, in the large load, the scale body There is a certain down, when the vehicle driving to the scale table, the scale body at the bottom of the connection with the foreign body, by the top force, can not really reflect the weight. Due to foreign objects to withstand the scale body instead of a part of the sensor load, so that the display becomes smaller. In this case, as long as the electronic truck scale scale body at the bottom of the foreign body can be resolved to solve the problem.

3, the instrument shows (owed) load

Phenomenon: There is a truck scale, empty scale, the weighing display instrument shows (owed) load.

First check the instrument, check the instrument parameters, with a small amount of weight for a standard calibration. Failure is still there, then check the junction box is damp, whether the wiring board Weld or rust, the terminal whether there is loose or string. Failure to solve the case, you can determine a (a few) only sensor damage. First power off the instrument, the load cell cable from the junction box from the wiring board, each time a sensor, and then boot to see the instrument display values. Here to note is that the instrument shows the value after the other sensor is still connected before the power. Check the damaged sensor, if the display value returned to normal, you can determine the fault sensor.

4, according to the instrument error prompted to find fault

Now the electronic instrument has a self-troubleshooting function. If a fault occurs, the instrument will usually display “E number” indicating an error. We can analyze the problem according to the error statement in the instrument manual. This is what is commonly referred to as the “code diagnostic method”.

As the electronic truck scale is installed in the wild or open areas, the probability of failure is high and cause a lot of causes of failure, and sometimes there will be several fault phenomena at the same time, so we ask us in the truck scale failure, Analysis, inspection, conditioning. Electronic truck scale fault handling is a more complex work, requiring the staff to have both theoretical knowledge, but also practical skills, in dealing with truck failure, you can use a variety of methods, careful analysis of the cause of the failure, a detailed examination may occur Failure of the link, in order to quickly and accurately troubleshooting.
