In fact, many minor problems can be avoided, as long as more attention is paid in practical application. This paper briefly introduces the matters that should be paid attention to in the maintenance of elevator advertising machine display screens in indoor buildings:
1. Choose a stable voltage environment. Because the advertising machine display screens are placed in public places, although they are all indoors, the unstable voltage may also cause equipment damage.
Therefore, the installation environment of building elevator advertising machine display screen must have a stable voltage, and must not share a power supply with high-power equipment such as elevator power supply.
If you choose a place with unstable voltage, it is easy to cause the advertising machine to work unsteadily, or even burn the advertising machine display screen, causing unnecessary trouble.
2. Ensure ventilation and heat dissipation. In the process of using the advertising machine display screen, it is not allowed to block the ventilation holes and speaker sound holes on the housing of the elevator advertising machine display screen in the building, nor to place it near the radiator, power supply or any equipment that affects its normal ventilation.
3. Close the work. If the advertising machine display screen of building elevator doesn't work for a long time, please open the anti-theft lock to turn off the 220V power supply and let the advertising machine display screenstand completely.
4. Do not disassemble and repair by yourself. Don't disassemble or repair the advertising machine display screen of the building elevator by yourself to avoid high voltage electric shock or other dangers. Please ask professional maintenance personnel to complete all maintenance work.
