Excavator abnormal high temperature alarm, the reason is actually a fuse.
A digger failed to find the cause of the high temperature malfunction of the excavator and tossed the whole machine over and over. Finally, it was discovered that a fuse was burned. Are you crashing in this situation? Recently, Mr. Ya'an's Master Wang had gone through a rough repair process. When he finally found the cause of the accident, he was almost laughed at.
The story happened one evening when Mr. Wang was about to leave work. Suddenly, the cab Rang "toot beep" and the high temperature warning lamp was on the dashboard. Check carefully, the water temperature is normal, the refueling door is invalid, and there is nothing unusual in getting out of the ring.
What shall I do? Call for help. When Mr. Wang described the trouble to the maintenance master, the teacher decided that it was a circuit fault and suspected that the water temperature sensor was broken. Then the master telephones long distance to guide the maintenance, a lot of places have been checked, and finally the water temperature sensor has been pulled out, the result of opening the key or the alarm. Because it is already dark, we can only wait for the teacher to repair it tomorrow.
The second day, early in the morning, I tried to strike a fire with an anxious mood. The result was that the high temperature alarm was always "toot beep", and it was not a face to face. By 10 a.m., the night's rescue star finally climbed up the mountain. The electrician came to work. The circuit, sensors and computer boards were searched all over the time, and all components were found to be good. After a while, the electrician: is the circuit board broken?
The electrician decided to try the circuit board for other excavators. At this time, Mr. Wang said, "the electric fan doesn't turn either. The fan is connected to the line from the small side lamp in the driver. Can it be that the fuse is broken?"
As a result, the electrician was checking, and the fuse was broken. After changing the fuse, everything was normal: the alarm disappeared, the refueling was normal, the small fan buzzed up again! This is the turn to the electrician master: No, the line and the GPS position is a line, do not have to give the bank the line should be null and void... In any case, finally repaired, and delayed the construction period of one day, the electrician chew for a day, finally spent 300 yuan for a small fuse, he was all angry.
Here, the lesson of money is to warn colleagues: circuit failure first check the fuse! Although this is understood by primary school disciples, they are often left behind by professional teachers.
