A,When the human body or objects hinder the operation of the swing arm, the system will continuously detect 1-5 times, 5 seconds each time. If the obstruction is not removed, the system will automatically stop in the normally closed state, and part of the components are in the hibernation state to effectively avoid burning out the original components. Within the specified time, the system automatically returns to normal.

  B,When the system cannot detect the reset signal normally (i.e. the swing arm hitting equipment box), the system will automatically detect 1-5 times, 5 seconds each time. If the reset signal cannot be detected all the time, the swing arm will automatically return to the normal locked state. (This protection function explains: even if the reset optical couple is damaged, the system can still insist on using, will not burn out the circuit or motor phenomenon.)
