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.
S2 CONNECTOR
The S2 connector is used to connect the 9700W wire feed control to a 9700T travel control. In certain
circumstances, it can be interfaced with a PLC or other control interface. Miller Welding Automation can
provide standard connecting cables to be connected to the S2 connector on the 9700W control. If you need
to provide your own cable, it should be fitted with the following:
Amphenol plug 97-3106A-20-27P
Cord Grip 97-3057-1012-1
Pin Connection Details
Connections should be made as shown below.
REMOTE START INPUT (Pins A & B)
Function: When this circuit is completed, the 9700W control will start the programmed sequence. The
process will continue until this contact is removed.
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.
EMERGENCY STOP INPUT (Pins C & D)
Function: When this circuit is opened, the 9700W control will initiate an emergency stop sequence.
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. Logic must be normally closed.
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.
AUX1 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.
REMOTE EMERGENCY STOP OUTPUT (Pins I & J)
Function: When the emergency stop button is pressed, this contact will open. This will prohibit the
operation of the secondary 9629 control.
Electrical: We supply a dry relay contact capable of handling 110VAC at 0.6A.
