Three Common Faults and Handling Methods of Dynamic Weighing Scales

2025-02-12

I. The touch - screen of the dynamic weighing scale has no response after power - on

Check whether the power supply is normal and whether the power switch is damaged.

Check whether the earth - leakage switch in the electrical box has tripped.

Check whether the switching power supply itself is damaged.

Check whether the 24V circuit is short - circuited and whether the fuse is blown.

Check whether there are quality problems with the touch - screen itself.

II. All three belts of the conveyor line do not roll

Measure whether the 24V voltage output by the switching power supply is normal.

Check whether the communication between the touch - screen and the PLC is normal. (There is an option called "PLC - IO port" in the "System Settings" of the "Main Menu" on the touch - screen. It is used to check the communication between the touch - screen and the PLC, and can check whether there is a communication fault.)

III. A single section of the conveyor belt of the conveyor line does not work

Check whether the timing belt is damaged or jammed.

Check whether the conveyor belt is blocked by foreign objects.

Check whether the connection terminals of the motor are loose or fallen off.

Use the replacement method, swap the motor driver and the motor to see whether it is a driver problem or a motor fault.
