Error message
Possible cause
Remedy
Err 20
Coolant
The flow quantity of the torch coolant
has fallen below the permissible
minimum -> the coolant flow is dirty or
cut off because the tube package has
been unsuitably installed
The flow quantity of the torch coolant
has fallen below the permissible level
Check coolant level and refill if necessary
• Check coolant level in the reverse cooler
• Check coolant lines for leaks and kinks
• Check that the coolant inlet and outlet on
the plasma torch is not blocked
Reset error via robot interface (reset error)
Err 22
Excess temperature in coolant circuit
Coolant temperature exceeded
The temperature of the coolant is too
high
• Check coolant level in the reverse cooler
• Check temperature nominal value on the
cooling unit
Reset error via robot interface (reset error)
Err 23
HF choke excess temperature
High frequency blocking inductor
excess temperature
The excess temperature of the high
frequency blocking inductor has
triggered
• Allow equipment to cool down
• Adjust processing cycle times if
necessary
Reset error via robot interface (reset error)
Err 51
Error in emergency stop circuit
(interface for mechanised welding)
• Check the external shut-down equipment
• Check plug-in jumper JP 1 on PCB
T320/1
NOTE
If the industrial bus interface is connected error messages are output via the respective
interface. It may occur that error messages output from the power source and the
interface differ.
Please note the relevant documentation of the accessory components.

7.3.1
Interface for mechanised welding
WARNING
No function of the external shut-down devices (emergency stop switch)!
If the emergency stop circuit has been realised using an external shut-down device via
the interface for mechanised welding, the device must be set for this setup. If this is not
observed, the power source will ignore the external shut-down devices and will not shut
down!
• Disconnect jumper 1 on PCB T320/1 (Tetrix) or M320/1 (Phoenix / alpha Q)!
