Many items will have various malfunctions over time. These are all normal. For a gate, the most common malfunction is that the gate rod sometimes drops and sometimes doesn't. How to solve this? The following article will introduce the relevant content briefly.

First, check if there is electricity and see if the fuse is burned out. If the fuse breaks, then a more comprehensive inspection is needed. If it is found that the motor of the electric gate is running well but still cannot be opened or closed, then measure the blue, green, and gray three limit signal lines to see if there is a short circuit. This is because the automatic stop of the door is sensed by the limit sensors K1 and K2. If both sensors K1 and K2 have a short circuit, it is equivalent to the door being limited at the opening time limit and the closing time limit, causing the inability to be opened or closed.

The most likely problem seems to be a controller issue. Analysis of the fault of the gate controller: When the automatic gate's manual indicator light is on, it is in the automatic state, indicating that the ground sensor is functioning. When in use, it is generally set to the automatic state, that is, the light is on. If the light goes out, it indicates that the ground sensor is not functioning. Another common problem is that the gate cannot operate normally up and down.

There are several main reasons for this situation:

Whether the three-way button is reliably connected to the gate control box, whether the plug wiring of the button is loose, whether the remote control is in the code loss state, and whether the button or the gate control box has any abnormalities;

The gate rod of the automatic gate shakes more significantly at the vertical or horizontal two limit positions. According to experts, the cause of this fault is that the fixing clamp or the screws of the chassis are loose, or the balance spring is broken. The main solution is to check the gate rod of the automatic gate or the fixing situation of the screws, and if it is loose, it should be replaced in time. Another method is to open the chassis door and check if the balance spring has broken. Regarding how to handle the common faults of the gate rod, for automatic gates, if such a situation occurs, they should be replaced immediately.
