The elevator will automatically shut down after being idle for a long time.

The reasons and solutions of automatic closing of elevator doors without moving for a long time are as follows:

1, due to the wear or improper adjustment of the switch contacts of the safety touch panel or the failure of the elevator door system caused by the door light curtain, it is often the case that the door cannot be closed automatically or clamped after opening. In this case, it is important to check whether the safety touch panel switch is intact and whether the door light curtain is effective.

2. If the elevator door cannot be closed automatically after it is opened because the door opening button in the car is stuck or the elevator button outside the hall is not released or pressed, check whether the door opening button in the car is open, which means that the door opening button is stuck. If the elevator button outside the hall gets stuck, it will stay on. So when the elevator button outside the hall is not lit on time, it means that the elevator button outside the hall cannot be closed automatically.

3. Bad limit switches in the door system will also lead to door closing failure. Common reasons are that the limit switch at the door opening terminal does not act or the limit switch at the door closing terminal does not reset.

4. The failure of the control panel of the door system will also lead to the failure of closing the door. Different manufacturers use different doors and control panels, but all manufacturers have related indicator lights on the door crane control panels, and it can be judged whether there is a fault in the door crane panel through the indicator lights on the door crane panel.

5. The failure of the mechanical part of the portal crane control system is also the main factor causing the door failure, such as the broken door chain or belt, or the broken wire rope, and the serious wear of the door roller on the door hanging plate, which will cause the elevator to fail to close or open the door.

6. Damage to the door motor will also cause the elevator door to fail to open or close. Usually, the probability of damage to the door motor is small.
