Several self-check methods when the automatic door cannot be opened and closed normally
There are two situations when an automatic door cannot be opened and closed normally. The automatic door always stays closed and cannot be opened, the other is that the automatic door always stays open and cannot be closed.
The first type: the situation that the door moves but cannot be closed. The reason is that the sensor has a door opening signal input, that is, there are interference objects within the sensor's sensing range, such as direct sunlight, moving objects, and Stabilize the light source, etc. You can test whether the automatic door cannot be closed due to the interference signal of the sensor by disconnecting the sensor signal line.
The second type: The automatic door is always open. The cause of this automatic door failure may be that the sensor is damaged. The door opening signal is always input to the automatic door controller. It may be that the automatic door remote control or the mode switch is adjusted to the open state. If an access control system is installed, the relay of the access control system may be damaged. In addition, the automatic door cannot be opened and closed normally, you can also refer to the following automatic door maintenance methods to solve:
Reason 1
The top of the door leaf is in contact with the beam
Method: Adjust the gap between the door leaf and the beam
Reason 2
The door leaf is in contact with the ground rail
Method: Adjust the height of the door leaf
Reason 3
Method: Re-place the door leaf into the track
Reason 4
The door leaf is not vertical
Method: adjust the position of the ground rail
Reason 5 The sensor is faulty or not connected to the hub
Method:
1. If the sensor fails, replace it with a new one
2. Check whether the sensor is connected to the hub
Through the above analysis, it should basically be able to solve the automatic door failure that the automatic door cannot open and close normally. In the actual automatic door maintenance, it should be simple to complex, first eliminate the automatic door failure with simple reasons, and then gradually troubleshoot other failures.
