General operating problems
7.4.1
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!
7.5
Vent coolant circuit
Coolant tank and quick connect coupling of coolant supply and return are only fitted in machines
with water cooling.
To vent the cooling system always use the blue coolant connection, which is located as deep as
possible inside the system (close to the coolant tank)!
