Thermal cycle alarm over use of the machine.
1) Machine is connected to automatic equipment and its usage is more than the maximum. 2) The machine has poor cables and the output voltage drop in these cables is consistent. 3) Wrong calibration of the machine.”
1) Check the name plate maximum usage levels in term of current voltage and duty cycle 2) Check the accessory cables and torch. 3) Check the calibration or replace the main con- trol board.”
ALL
Err: 90
Pre-charge alarm
1) Power transistor broken. 2) Electrolytic capacitors broken. 3) Missing connection of the DC BUS to the invert- er board. Auxiliary connection between inverter board and interface board not well connected."
