Fault I: After power on, the led controller fault light (ERROR) flashes, the point light source is off, and there is no animation effect output?
Answer: The controller does not read the card correctly and does not output a valid control program. The possible reasons are:
(1). The SD card is empty and there is no file
(2). SD card program file name error
(3) The SD card is not formatted as required before copying the effect file
(4). The effect file in the SD card does not match the lamp chip and controller model, you need to contact the manufacturer to recreate the effect file
(5). Test after replacing the new SD card to rule out the possibility that the SD card is broken
Fault Ⅱ: After power-on, the led controller indicator is normal and there is signal output, but the point light source has no effect change?
Answer: There are generally the following reasons for this situation:
(1). Check whether the signal line of the lamp and the controller are properly connected
(2). The signal of the external control lamp has an in/out direction, check whether the control signal enters from the signal terminal of the first lamp
(3). Check whether the selected model when making the effect file *.led in the SD card is consistent with the chip used by the current lamp
(4). The luminaire and the controller must share the same ground, that is, the GND of the luminaire and the GND of the controller must be connected together
Fault Ⅲ: After the controller is connected to the lamp, the effect changes, but the lamp flickers, and the controller indicator shows normal?
Answer: (1). The ground wire between the controller and the lamp is not connected
(2) The power supply voltage of the lamp is insufficient
(3). The effect made in the SD card is wrong, and the lamp chip selected when making the effect does not match the chip of the actual lamp
(4). The distance between the controller and the headlight is long (distance> 10 meters), and the signal transmission is unstable
Fault Ⅳ: After power-on, the controller and some of the lamps in the front work normally. Starting from a certain lamp, the lamps in the rear are abnormal?
Answer: In this case, the latter part of the lamps fails to receive the signal normally, and the reasons are usually as follows:
(1). Individual lamp IC failure or damage to the signal line before and after the lamp, generally replace the first non-lighting lamp in the abnormal position or the lamp in front of it.
(2). When writing the program, the number of point light sources is less (for example, 9000 are actually used, and only 8000 are written in the program), so there is no animation effect in the latter part, and you need to contact the manufacturer to rewrite the program
Fault Ⅴ: After power-on, the controller works normally, and the lamp changes position abnormally, which is different from the designed video screen effect?
Answer: This situation is caused by the inconsistency between the order of installation of lights and the designed wiring diagram. It is necessary to adjust the order and position of the installation of lights according to the designed wiring diagram, or input the actual arrangement of lights. Reprogram the program on the computer
Trouble Ⅵ: After power-on, the point light sources can change normally, but how many individual point light sources display colors are different from others?
Answer: This situation is generally due to damage to one of the three chips of the lamp beads R, G, and B, which causes the display to be lacking in color. You only need to replace the problematic point light source.
Problem Ⅶ: SD card cannot be formatted when copying programs?
Answer: (1). First confirm whether the protection switch on the side of the SD card has been unlocked, and the direction of unlocking is the gold needle end of the SD card.
(2). The protection lock has been opened as required, but it still cannot be formatted. In this case, the SD card reader is broken. Please replace the SD card reader.
(3). If the above operation still cannot solve the formatting problem, please replace the SD card and retest
