The so-called pseudo-fault refers to the failure of the machine is not caused by damage to their components but due to improper use caused by the difficulties or can not be used. Automatic door pseudo-failure is the most common failure of automatic door leaf stop running, automatic door stop switch, automatic door running noise is not smooth, automatic door feeling sluggish.

 

Today, the use of medical automatic doors gradually universal, due to the use of induction control system, can automatically open and close the door, which greatly facilitates our daily life, of course, it will also have a breakdown, there will often be some false failure situation , Here are some of the following situations and how to deal with:

 

The first false phenomenon

 

Medical automatic door leaf No matter whether someone passes by, it will keep on and off on its own.

 

1, there may be moving objects into the sensing range of the sensor, such as pedestrians, vehicles, flags and even shaking shadows;

The company is located in:
 

2, Probably sensing the detection range of the probe is too downward adjustment, when the door is about to close, the probe also sensed the activities of the door fan, the detection sensor mistakenly believe that there are moving objects, so that the door opens again;

 

3, the sensor may be fixed on the beam plate jitter phenomenon, so that the probe along with jitter, resulting in non-stop switch door.

 

The second kind of false failure phenomenon

 

Medical automatic door leaf loud at run time, most of these failures appear in the automatic doors have been used for a long time.

 

1, take the door leaf spreader for a long time to run a certain amount of wear and tear, such as the appearance of only minor wear and tear, you can clean the track and go round, you can give the wheel bearings add a little lubricant, but can not give Track and plastic go round the oil, because easy to attract dust after oiling, will make the wheel damage faster;

 

2, some metal connectors are loose, just re-reinforcement can be;

 

3, the activities of the door leaf and fixed the door there is the phenomenon of grinding 檫 noise;

 

4, the lower part of the guide system damage, will result in a large sound phenomenon, so, need to be replaced;

 

5, the beam in the initial construction did not do well, or resonate with the ceiling of the upper part of the phenomenon.

 

The third pseudo-fault phenomenon

 

Medical automatic doors do not move, you should have a look at this time for it to be charged.

 

1, take a look at the activities of the door whether the phenomenon of mopping the floor, if this phenomenon, the door is very difficult at start-up, the main controller will think there are obstacles and self-locking protection to stop the door leaf movement;

 

2, take a look at the door spreader part of the wheel is not off from the track down, if this phenomenon, the door will not go.
