Working principle
Firstly input the load curve table of the crane into the memory through the programmer, and then set various working condition parameters through the function of the man-machine dialogue window of the panel, and the host can work. It collects the signal from the weight sensor, and after the signal is amplified, it is converted into a digital signal by the A/D converter, and sent to the microprocessor CPU for calculation; After the comparison process, the relevant data is displayed, and on the other hand, compared with the preset limit values of weight, amplitude, angle, etc. in the instrument, when it exceeds 90% of the rated weight, it is issued. Sound and light warning. When the rated weight exceeds 100%, an audible and visual alarm is issued. When the voltage exceeds 105%, the control signal is output, and the control circuit that the crane runs in the dangerous direction is automatically disconnected, but the safety direction is allowed to operate, thereby achieving the purpose of safety
protection.
