Ohmic and Conductive Torch Touch Off.
The “T in” screw terminal on the THC TX board is dedicated for conductive/ohmic touch off.
By design the “T in” terminal on the TX board is intended to be used with the Torch Conductive Tip. This conductive
torch tip connection can be used with or without a separate stand alone Ohmic sensor box. By definition the T in
connection on the TX board is CNC12/Acorn Input 9. No need to define an input assignment to input 9 (you won’t
see it in the Wizard Input Definitions menu) as input 9 is only used for conductive Torch Touch Off.
Green LED = Conductive tip is grounded
Red LED = Conductive torch tip is not touching anything.
