3: PLC Input 1. Short this pin with Pin1 (GND) to trigger an ac-
tion.
4: PLC Input 2. Short this pin with Pin1 (GND) to trigger an ac-
tion.
5: Weld Ready. Pull this pin up to high (+12V) by connecting it
with Pin 2 (+12V). Signal will go low (0V), when weld is ready.
6: Alarm. Pull this pin up to +12V by connecting it with Pin 2
(+12V). Signal will go low 0V, when alarm has occurred.
7: PLC Output 1. Pull this pin up to +12V by connecting it with
Pin 2 (+12V). Signal will go low 0V, when this output has been
enabled.
8: PLC Output 2. Pull this pin up to +12V by connecting it with
Pin 2 (+12V). Signal will go low 0V, when this output has been
enabled.
Note: If you choose to use the software E-STOP alarm as one
