Pin Connection Details
Connections should be made as shown below.
JOG LEFT (Pins A & B)
Function: When this circuit is completed, the 9700W will jog the wire the same direction as the left arrow if
in a Run screen.
Electrical: You can connect a dry relay contact or an open collector signal, Pin A is high, Pin B is low. Either
one must handle 12VDC at 4mA.
JOG RIGHT (Pins C & D)
Function: When this circuit is completed, the 9700W will jog the wire the same direction as the right arrow
if in a Run screen.
Electrical: You can connect a dry relay contact or an open collector signal, Pin C is high, Pin D is low. Either
one must handle 12VDC at 4mA.
PULSE LOCKOUT INPUT (Pins E & F)
Function: When the control is connected to a power supply with pulse current facilities, it is sometimes
necessary to the wire feed with the current pulsing. When the control is connected to the current
background signal through these connections the wire can pulse with the arc.
Electrical: You can connect a dry relay contact or an open collector signal, Pin E is high, Pin F is low. Either
one must handle 12VDC at 4mA.
AUX2 OUTPUT (Pins G & H)
Function: When the “Arc On” signal has been received by the control, this contact closes, relaying the signal
to anther device to initiate its function. This contact opens during the stop sequence.
Electrical: We supply a dry relay contact capable of handling 110VAC at 0.6A.
EMERGENCY STOP OUTPUT CONTACT (Pins I & J)
Function: When the emergency stop button is pressed, this contact will open up. This will prohibit the
power supply from initiating or maintaining a welding arc.
Electrical: We supply a dry relay contact capable of handling 110VAC at 0.6A.
PULSE LOCKOUT OUTPUT (Pins K & L)
Function: Permits the 9700W to pass a pulse signal to another device. This signal would be used if it is
desired to pulse a third party control. It is not used with Miller Welding Automation 9600 series controlled
equipment. The signal from these pins directly follows the Pulse Lockout Input signal.
Electrical: This is an open collector output, Pin K is high, Pin L is low.
AUX3 OUTPUT (Pins M & N)
