THC_TX Features
THC_TX has connections for arc voltage measurement and torch to part touch detect. The analog arc voltage
may be supplied as 0 to -10V connected to the ANLV terminal. The plasma cutter must have a divided arc voltage output
to get 0 to -10V input. Typically, the divider ratio is 50:1 or 40:1. The analog inputs measure voltage that is negative with
respect to THC_TX and work table ground.
The touch detect input is activated when the TIN terminal is connected to THC_TX and work table ground.
