Computer sewing equipment maintenance and maintenance methods

1. A reasonable working environment for computer sewing equipment. First of all, do not install the equipment in a place with strong electric noise or high-frequency welding. The strong electric noise will affect the equipment or cause the equipment to not work normally.

2. It is advisable to keep the indoor temperature of 5-35℃ in the workshop, too high or too low temperature will affect the normal operation of the equipment.

3. Humidity will cause short circuit inside the machine. The relative humidity should be kept at 45-85%, and it should not be installed with sewing equipment with water vapor.

4. Dust easily corrodes the circuit board, so the equipment should be kept clean, and the workshop should also be kept clean.

5. A stabilized power supply (power supply bureau or installation of a stabilizer) must be used, with grounding function (if the power supply must be cut off, the machine must be shut down first). For example, it is strictly forbidden to put a live wire on the 380V three-phase four-wire three-phase live wire, and then use a neutral wire as the 220V power supply as the power cord of the computer sewing equipment. This often causes frequent equipment accidents or crashes. (The main reason is that the voltage is too high or too low). Maintenance personnel often don't pay attention to this, and desperately adjust the equipment, which causes a lot of unnecessary trouble. In fact, only the power supply is stabilized, and the equipment will return to normal immediately.

6. Any computer sewing equipment must be maintained under the rated voltage of the power supply bureau, and no more than ±10%. Excessive or insufficient will affect the equipment not working normally, but the power supply must be greater than the power consumption of the sewing machine.

6. The machine should avoid direct exposure to the oblique outdoor sunlight. The temperature generated by the light on the machine head will easily burn the display, and the light on the rack will easily burn the chip in the main machine and cause major accidents, so the sun can shine in. The workshop has a door and curtains.

8. Turn off the power during thunder and lightning, because lightning will directly affect the normal operation of the equipment.

Use computer sewing equipment correctly

Boot sequence: peripherals (power switch)-display-host.

Shutdown sequence: host-display-peripherals.

Do not switch the machine frequently, otherwise the current will easily impact the hardware, and the computer will suddenly shut down when it is working, which may damage the computer.

When shutting down, you must turn off the startup switches of all running programs, and then exit in the normal order, otherwise the system will easily be damaged and cannot be started.

Power supply hardware and software status

After turning on the device, the operator should observe the self-inspection of the equipment, and do not touch the computer (host) during the self-inspection; click on each system of the equipment to view the operation of the equipment.
