Use a multimeter to measure whether the power board transistor M5 malfunctions?

Use a multimeter to measure whether the power board transistor M5 malfunctions? If there is any problem: change the transistor of the same model. Use a multimeter to measure the plug 4 and 5 of the socket CZ6 on the power board in the control box, and the exchange voltage should be 63V.

 

Inspect whether the signal line connection between the main control board and the power board is reliable. If not abnormal: remove the embroidery frame. Use the resistance file of a multimeter to check whether there is a short circuit between the wire-deduction magnet lead and the frame (resistance is 0): Inspect each wire-deduction magnet in tu, and replace it. The accurate resistance value should be 10; or more.

 

Use a multimeter to measure the DC voltage of pins 2 high speed embroidery machines price and 3 of the socket CZ3 on the power supply board in the control box should be 90V u0026 plusmn; 10%. Inspect whether the connection between the buckle magnet and the power board can be reliably connected: check to make the connection reliable. If it is not accurate: Check whether the plug-in department is superior in battle; exchange the power board.

 

ufeffReflective methods and processing steps for embroidering machine thread deduction: Inspect whether the main control board has a wire-cut signal input, can the wire-cut indicator L32 (KX) be lit? If L32 (KX) does not light up, it indicates that there is a problem with the control board (no signal input): exchange the main control board.
