What are the common faults of stainless steel expansion door? Do you know how to deal with the common faults of stainless steel electric expansion door? Haifeng stainless steel expansion door manufacturer introduces the common faults of stainless steel expansion door to you here. Don´t panic when you come across this problem. We´ll work it out.
1. Stainless steel electric expansion door cannot be opened or closed
The biggest problem of stainless steel expansion door is that it can´t be opened or closed. If there is such a problem, when repairing the stainless steel expansion door, first check whether there is power supply on the expansion door and whether the safety pipe is burnt. If the fuse is broken, a full inspection must be carried out. Generally speaking, if it can´t be turned on or off, there is a problem with the circuit. Therefore, it is necessary to measure whether the red, white and yellow leads are connected, mainly to see where the three lines are.
2. Trembling of stainless steel electric expansion door during use
In the use of stainless steel expansion door, there are often some buffeting phenomena, sometimes more and more serious. For the occurrence of this problem, the maintenance of automatic stainless steel expansion door is mainly to find out the reasons, such as whether the length of the brake rod is not directly proportional to the spring tension, if the low rod does not vibrate, the lifting rod vibrates, which means that the spring tension is too strong, of course, if the opposite, it means that the spring tension is insufficient, it should be adjusted appropriately.
3. Stainless steel electric expansion door, automatic opening and reversing
Another common problem in the maintenance of automatic stainless steel expansion doors is the automatic reversal of the door opening. The reason for this should be the poor anti-jamming ability of infrared ray, or the wrong action caused by shooting induction. Generally speaking, the way to solve this problem is to code or replace PCB hand. Of course, if there is a problem with infrared, the best way is to replace it to ensure its normal use.
4. The stainless steel expansion door can be opened and closed, but cannot be closed.
If it can be switched, there is no problem with the red, white and yellow wires of the motor, and the signal wire is not short circuited. The main reason is that the limit signal is not sent to the controller or the limit function of the controller is damaged and cannot stop automatically, so it needs to be replaced.
