the 37 pin Control Signal connector to the I/O common (pin 28 or pin 32). See
Appendix B, Electrical &
Data Connections for connection details.
1. Connect weldhead 2 to the 4 pin Standard Air Valve Driver Output Connector.
2. Connect Weldhead 1 to the 8 pin Weld Head Connector.
3. Connect the Dual Weldhead Input (pin 13 on the 37 pin connector) to the I/O common (pin 28
or 32 on the 37 pin connector).

schedules will fire alternately with the Footswitch input. Do not use the RS-232 commands or
the Binary Schedule Select inputs to change weld schedules when Dual Weldhead operation is
active.
