1. Using high-quality LED light-emitting tube, high height, low light decay, large horizontal and vertical viewing angles.
2. The ink color is leveled*, the contrast is very high, the display color is uniform, and the picture is clear.
3. The surface of the cabinet is treated with the anti-corrosion technology of the shipbuilding industry to effectively ensure the service life of the display screen.
4. The wiring inside the box and the terminal of the cable are directly fixed on the terminal block, and the screen body has stable and safe performance during long-term work.
5. The cabinet + bracket structure can be used, the whole screen splicing has a high flatness, and the magnetic column adsorption method is adopted at the same time.
Display installation instructions and precautions
1) Steps to install the display box
*Step: Open the upper cover of the outer packaging of the box, remove the pearl cotton, and move out of the box.
The second step is to disassemble the anti-static tape and check the appearance of the cabinet for damage.
The third step is to open the back cover of the box and check whether all the screws, cables, and power cords are loose or fall off.
2) Precautions during installation
a. When moving the box, please handle with care, and put a protective layer (paper or carpet) on the ground to prevent
Bumps, scratches, drops, etc.
b. When installing the box body, it is not allowed to knock the box body with iron hammers or other iron objects, or kick the box body with feet.
Way of construction.
Detection of the power supply system of the display screen (distribution cabinet, switching power supply in the cabinet)
A. Check whether the live wire L, the neutral wire N, and the ground wire FG are short-circuited.
B. Check whether the neutral wire N and the ground wire FG are short-circuited, and the resistance value should be ∞.
C. Check whether the receiving board +5V power supply and GND (30~50Ω) are short-circuited with the ground wire FG, live wire L, and neutral wire N. The resistance value should be ∞.
D. Check whether the receiving board GND and ground wire FG, live wire L, and neutral wire N are short-circuited. The resistance value should be ∞.
E. Check whether the output +5V and GND of each power supply are short-circuited, and the resistance should be 30-50Ω.
Pay attention to the problem of display installation.
1) After the display screen is installed, take measures to prevent lightning strikes on the screen body. The main power distribution input terminal is connected to a lightning arrester.
2) Live work on the display screen is strictly prohibited (especially 220V input and output ports).
3) The sending system does not support hot plugging, so you must unplug the power cord before plugging in the wires between various devices.
4) During the hoisting process of the display box, it must be firmly fixed before hoisting. At the same time, it prevents the box from colliding during the hoisting process and causing damage to the display product.
5) During the installation process, workers must take safety measures (wear safety helmets, safety belts and other protective products).
6) When disassembling the control system board and other equipment, pay attention to anti-static (with anti-static gloves) 4. The wiring inside the box and the terminal of the cable are directly fixed on the terminal block, and the performance of the screen is stable and safe during long-term work. .
