Remote Memory Select Inputs (For 28-Pin Receptacle If Present) - Miller Maxstar 400 Owner's Manual

Continued from previous page, Section C.
11 Output Control Reference for pins 5 and 6.
12 Output Welders Chassis = Earth ground. Connected only if common potentials are needed between user equipment and the
welder.
19 Input High Frequency Arc Start Disable = Disables the arc starter from being activated when connected to pin 8.
21 Input Isolated EN Amperage Common = Paired with Pin 22.
22 Input Isolated EN Amperage Command = Paired with pin 21. Sets output amperage value for a Maxstar and the EN amper-
age value for a Dynasty. Value should be between 0.3 to 10V corresponding to the minimum to maximum of the
machine.
25 Input User Controlled Automation Select = Connect to pin 8 to active this mode.
26 Input Isolated EP Amperage Command (Dynasty models only) = Paired with Pin 27. Sets EP(cleaning) output amperage
value. Value should be between 0.3 to 10 volts corresponding to the minimum to maximum of the machine.
27 Input Isolated EP Amperage Common (Dynasty models only) = Paired with Pin 26.
28 Input AC waveform Generation (Dynasty models only) - User controlled polarity(EN or EP), frequency (20-400 HZ) and bal-
ance of an AC waveform. When this pin is not connected to pin 8 the weld output is EN. When this pin is connected to
pin 8 the weld output is EP. Alternating between connection and disconnection at different intervals creates the fre-
quency and balance of the waveform.
All other pins not used.
