After being analyzed and processed by the control module, it is transmitted to the communication module, and then the signal is transmitted to the designated monitoring point via the output terminal 11 inside the communication module. After the monitoring point receives the fault signal, it will send out a warning signal, which is received by the receiving terminal 12 and retransmitted to the inside of the control module.
