Shaded area indicates plasma interface assembly connections.
Plasma interface assembly other J3 and J4 connection points:
• J3-5 (+) and J3-6 (–) – Alternate Nozzle Contact. An optically isolated signal that indicates nozzle is in ohmic contact with work.
Ohmic contact is represented by a logic 1.
• J3-7 through J3-12 – Reserved for future use.
• J3-13 and J3-14 – Protective earth ground.
• J4-1 (+) and J4-2 (–) – Available 24 VDC, 500 mA maximum
• J4-7 and J4-8 – Pierce Complete signal used by power unit to time transition from pierce gas flow to cut gas flow. User enters this
time delay into THC. Output signal.
• J4-9 through J4-14 – Reserved for future use.
