Automated Plasma Interface 464
HD3070 Auto Gas I/O
The Interface to the HD3070
®
Auto Gas console is made through use of Single Ended and BCD
(Binary Coded Decimal) inputs. The BCD style of interface allows for exact settings by use of
multiple inputs being active at any time. The active BCD input values are summed together to obtain
the exact set point.
These I/O points are wired in the same fashion as our other Single Ended I/O points. The following
I/O points are supplied for use with the HD3070

HD3070 Part Program Support
The same valve setting data which is used at the Auto Gas setup screen may also be used within a
part program to configure the HD3070
®
for use. This code is used to select the valve and indicate the
valve set point.
Using a EIA-274D G59 code with the following format.
Example: G59 V65 B5
Misc. G Code
Valve Identity
V65 = Preflow Shield Gas - Valve 1
V66 = Preflow Shield Gas - Valve 2
V67 = Cut Shield Gas - Valve 3
V68 = Cut Shield Gas - Valve 4
V69 = Cut Plasma Gas - Valve 5
V70 = Cut Plasma Gas - Valve 6
V71 = Remote Plasma Gas Type
Valve Value
For Valves V65 – V70
A whole integer is used to set the desired percentage value.
For Valve 71
0 = Oxygen
1 = H35/N2
2 = O2
For the example given, the part program code (G59 V65 B5) would set the Autogas Preflow Shield
Gas valve to 5%. Multiple G59 codes can be used to set and adjust the all desired valves.
