plasma mode, pin 9 output is low, and the relay works for following purposes:
1. auto/manual signal, change from flame mode pin 21 to plasma mode pin 5.
2. arc voltage/capacitance switch signal, change to arc voltage mode after breaking DC24VG.
3. plasma arc strike output of CNC cutting controller is connected.
