When 03 years of contact excavator, is in a Kato 820-1 apprenticeship, there is a failure to excavate a machine, display alarm prompt, after the call to the machine repair master repair, I know that many excavators have a set of hidden "password", input this set of password, to see a lot of monitoring data excavators, This is like a long time ago DOS boot order, no one told you, you may not guess this lifetime.
Well, nonsense, I don't say much. In those years, every time I opened a brand model, I noticed and collected a way to enter the excavator computer.
1, Kato
Japanese machine in this respect is quite concealed, -R before the CAG model, when the work of the display display a OK, or the alarm prompt, you do not enter the computer system even the engine speed of how much do not know, let alone hydraulic pump pressure and other sensor data.
Kato -1, -2, -3, into the computer version:
As shown in the picture, first at the same time hold down the right lower corner of the K, L two keys do not hear the sound, and then press A, D, J can go into the system (really do not know when the Japanese are in the design, how do you think, why if ADJ? " Is it homophonic? After entering, it is all English (don't understand the dictionary, do not press, long time no operation will automatically exit), in fact, the data is some engine speed, pressure before and after the pump, the alarm record before the excavator, various sensor data, and the computer version and other information. (here we can't find the picture after entering it, who can take a picture on the excavator.)
Kato -R, -V, -6 entered the computer version:
As shown in the picture, first hold the top of the wrench on the top (after hearing the drop of a sound in about two or three seconds), in order to press E key idle key (auto slow) P key A key (the process press the hand of the wrench must hold down all the time), in fact, it is the lower right lower right key, the 4 keys can release the hand of the wrench key. As soon as the bottom confirmation key (menu) can enter the interface (this is how much you do not want to let you know, to design such a complex method of entry), in the future is also English, a variety of data, for the people who buy two phones, it is a little useful, there is a real working time of the excavator, so you can join. Test.
2, Kobelco
Kobelco -8 and -6 have different ways to enter the excavator computer, and here only -8 (super eight is the same).
Kobelco is relatively simple, a lot of people know that, when the key is in the turn off, hold the key in the middle of the first row do not loose hands, and then open the key power, it is OK.
After the Kobelco machine entered the computer version, nothing to see, a variety of invisible data, also can see the working time of the excavator (this seems to be able to change), buy two mobile phones can refer to, and Kobelco excavator eight to the super eight from the computer system version of the excavator can be seen, leading to the current eight to exceed eight You need to change the computer for the excavator.
3, Komatsu
Komatsu -6, -7 and -8 have different ways of entering the excavator computer.
Komatsu -6 model enters the excavator computer's method is: holds down the set key and the key after the monitor does not put, can enter.
Komatsu -7 models are: hold down the up button, and press 1, 2, 3, and keys.
Komatsu -8 is to hold down 4 keys and put them in 1, 2 and 3 keys in turn.
It is also a variety of data, including average fuel consumption, GPS data, pump pressure and pressure data of various solenoid sensors.
4, Sumitomo and Cath
Friends and Keith are the same as the same, so the way to get into the computer version of the machine is: when the electric door is in the ON file, the screen will enter the monitoring page after holding the horn key + rabbit key for 3 seconds.
Sumitomo A5 has an interesting function after entering the computer.
After setting up the password, people who do not know the password can not start the device.
5, Hitachi
Hitachi's direct injection machine and electronic injection machine are two ways to enter the excavator computer: direct injection 3G and -1 and previous models.
Start with the key to OFF and turn off the engine.
First press the SET switch, and then hit the key door to ON. When the screen is lit, loosen the SET.
Because this display screen is relatively small, the data you display can not be read without comparing the data.
After entering, press DISPLAY SELECT to display the selector switch, and the diagnostic item data will appear in turn. They are also basic data, such as working hours, engine speed, pressure of front and rear pumps and pilot pressure of each action.
Hitachi EFI (-3) first hit the key to OFF and shut down the engine.
Press the button on the upper right corner of the monitor keyboard and ring the key door to ON. After the screen skips "SYSTEM STARTING", the key can be loosened.
5, Carterpillar
Carterpillaralso wants to split the model, among which the AB model is the most complex.
The starting steps are as follows:
(1) when the warning switch is pressed, the power mode selection switch 17 is pressed until the power mode III indicator shines, and the warning elimination switch 36 and the power mode selection switch 17 are immediately unlocked.
(2) press the warning to remove the switch 36 until the warning is cleared and the indicator is flashing.
(3) the digital mode has now been completed, and the first number (power conversion pressure) will be displayed in the digital display. If the power mode selection switch 17 is too long to press, the digital display will continuously change the displayed number in the order of 8 functions.
Later Carterpillar model, can be directly through the screen menu into the computer system, but the need for password, the customer with the password 0001, display Chinese, repair the password FFF2, English interface, (D2 model is different passwords).
6, Sany from the menu bar, and there are 2 kinds of passwords.
The most common is: 31868
Each factory will enter the excavator computer design is very concealed, that is to let everyone do not change the data at will, if curious, go in and see it, once the data changes, it can be troublesome!
