First, the common fault causes and maintenance methods of LCD screen elevator:
LCD screen lifters have extremely wide range of applications, in different application environments, LCD screen regulators have different functions. Then the common causes of LCD screen elevator damage are as follows:
1. The power supply voltage is unstable, which is the main reason for damaging the elevator.
2. Excessive load is the main reason for the failure of the elevator motor.
3. The working time is too long, and the temperature of the circuit board of the elevator is too high due to poor heat dissipation.
Second, about the wiring requirements of LCD screen elevator:
LCD screen regulator, is the best match for LCD screen, with it, LCD screen can be hidden in the middle of the table, the desktop can be more neat. LCD screen regulators have been widely used in conference rooms, offices and other places. Below, I will introduce to you what are the requirements for the wiring of LCD screen lifters?
1. First make it clear that each LCD screen regulator has at least one VGA signal cable and one three-core power plug. The power cord can be connected in series with multiple function power strips as the power supply of the LCD screen regulator, and the VGA signal line is the unique display of the LCD screen.
2. The central control control needs to deploy a three-core control line, and the display screen elevator can connect the machine in series through its own RS485 interface, and then through the machine coding to control each controller and realize the lifting function of the elevator.
3. Each LCD screen elevator will come with a hand control line and hand control button, remote control line. One remote control can lift multiple LCD screen lifters.
4. If the display elevator needs to connect the motor with the LCD screen, it is necessary to add a countertop socket, and the socket signal line and the distributor connection can realize the function of multiple advances.
Third, the detection method of LCD screen elevator is as follows:
1. From the appearance, whether the power supply diode of the elevator is scorched and blackened and deformed. In the event of insurance failure, the damaged elevator is often visible from the outside.
2. Test whether the motor is lifted and lowered, check whether the circuit has electricity, if there is electricity, see if the positioning switch can bounce up, if the switch does not bounce up, it means that the positioning switch is broken.
