Error code Description
Err 3 Overvoltage
Err 4 Over heating
Err 6 Internal fault, secondary voltage over the limit.
Err 8 Maximum overheat time, machine doesn’t cool down fast enough. Only machine
shutdown and restart removes error.
Err 61 Water connection, water cooled gun connected without cooler.
COO Ler Cooler error:
- Cooling liquid over- / under pressure state
- Overheated alarm
BuS Err Communication between panel and power source isn’t possible
Err rSt System error, machine makes reset itself.
