DC24V Rolling door motor fault solution

The AC/DC controller in the DC rolling door motor solves the technical problems of DC24V, minimizes the failure rate, and eliminates the user's fear of the low quality of the old DC controller and the controller of other manufacturers. It is the user's latest alternative product, the AC and DC rolling door. Most of the control circuit of the machine is located in the control box, and the main machine only has the power connection line, the failure rate is low, the maintenance is convenient, and the trouble of removing the main machine and the door curtain during maintenance is avoided:

1. Observe whether the 2 fuse tubes on the control box are burned out: if the 15A fuse tube is burned out, the problem may lie in the motor brake part (the load current is too large), at this time the three indicator lights are off; if the 5A fuse tube is burned out , The problem may lie inside the control box.

2. If the two fuses are normal, observe whether the "charging" indicator light is on: not on, indicating that the external power supply (mains 220v) is cut off, and the built-in battery may be undervoltage at this time; if it is on, use the remote control to see Whether the control box emits a corresponding beep, determine whether there is a problem with the remote control handle.

3. If the controller is normal, especially check whether the 7 wire ends in the connector of the power cord of the host are loose or fall out (poor contact).

4. Finally, check whether the wire end of the mainframe terminal box is off. The fastest way is to take a set of normal controllers to connect and determine whether it is a controller problem or a host problem.
