Monitoring welding voltage
The output voltage is measured via X19 of the pc-board DK-MAPRO. As well as the Master and the Process
(DSP) are measuring the output voltage independently.

If the Master is measuring a voltage higher than 100V, the machine will stop and displays
E06
(secondary
overvoltage). If the Process should detect a voltage higher than 100V, the machine will stop and displays
E20
(Overvoltage secondary).
If no voltage can be measured at all, then machine will stop and displays also
E20
.
Possible reasons could be:
- disconnected measuring wires (red and blue)
- loose connection of the connectors
- interchanged wires (red with blue)
If the Master is measuring another voltage than the DSP, the machine will stop and displays
E09
(V/A measuring
error).
If the Process is measuring an output voltage >60V when the machine is not welding (standby), the machine dis-
plays the error message
E21
(Output voltage/current).
