1. Restart.
2. If the error persists, send for a service technician.
3
External RAM error
The microprocessor is unable to read/write from/to a certain memory position in its
internal memory.
This error does not disable any functions.
1. Restart.
2. If the error persists, send for a service technician.
4
5V power supply low
The power supply voltage is too low.
The current welding process is stopped, and cannot be restarted.
1. Turn off the mains power supply to reset the unit.
2. If the error persists, send for a service technician.
5
Intermediate DC voltage outside limits
The voltage is too low or too high. Too high a voltage can be due to severe
transients on the mains power supply or to a weak power supply (high inductance
of the supply or loss of a phase).
The power unit is stopped, and cannot be restarted.
1. Turn off the mains power supply to reset the unit.
2. If the error persists, send for a service technician.
6
High temperature
The thermal overload cutout has operated.
The current welding process is stopped, and cannot be restarted until the cutout
has reset.
1. Check that the cooling air inlets or outlets are not obstructed or clogged with
dirt.
2. Check the duty cycle being used, to make sure that the equipment is not being
overloaded.
8
+24V power supply (cooling unit)
The voltage is too high or too low.
1. Send for a service technician
8
Low battery voltage +3V (in the control panel)
Battery voltage too low. If the battery is not replaced, all stored data will be lost.
This error does not disable any functions.
1. Send for a service technician to replace the battery.
