Detailed Answer
Mining remote control signal-loss protection: on communication interruption (out of range/obstruction), the receiver automatically cuts output and stops equipment within 1 second (safety-critical underground). Lideral LD series watchdog + signal-loss protection; signal recovery requires re-operation. Complex underground environment makes signal-loss protection the core against loss of control.
