Monitoring output voltage
The output voltage is conducted via a low pass filter (pc-board DP-UFI-BO) to the MAPRO pcb. The voltage
is measured by the Master as well as the Process.
Schematic
If the Master is measuring a voltage >100V, the machine will stop and displays
E06
(secondary overvolt-
age). If the Process should detect a voltage higher that 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 ma-
chine displays the error message
E21
(Output voltage/current).
