5.14.1 Automation interface
WARNING
No function of the external interrupt equipment (emergency stop switch)!
If the emergency stop circuit has been set up using an external interrupt equipment
connected to the interface for automated welding, the machine must be configured for
this setup. If this is not observed, the power source will ignore the external interrupt
equipment and will not shut down!
• Remove jumper 1 on the T320/1, M320/1 or M321 PCB!
These accessory components can be retrofitted as an option > see 9 chapter.
