3.5 Protective Functions

The machine’s each power supply PCB is equipped with an overcurrent protection circuit

designed to cut off the output of each power supply when they go ON.

While the signals RMT1 and RMT2 from the main controller PCB are used to turn on the

output of each power supply PCB, if 3VB stops from the composite power supply PCB be-

cause of a fault in the high-violate output or melting of the fuse, all outputs of power will be

cut.
