Code designation cause remarks
E13-01 Temperature sensor diodes After a certain time, no rise of the tem-
perature could be measured.
Sensor faulty or disconnected (loose
connection)
-check sensor and its connection at DRV
-check wiring between DRV (X6) and
MAPRO (X7)
- check flat ribbon cable between DRV and
MAPRO
for details see page 46
E13-02 Temperature sensor primary modules
E14-00 Supply undervoltage The 16V supply voltage of the MAPRO is
too low (<12V)
-check mains supply
-check wiring between NEFI, control trans-
former, DRV and MAPRO
-check fans
for details see page 54
E15-00 Current offset Contact problem between MAPRO and
shunt resistor or shunt wires not con-
nected
-check shunt and its wiring
-check torch and central connector (trigger
wires to power cable)
-replace shunt resistor if necessary
for details see page 51
E15-01 Current offset FPGA The offset voltage across the shunt resis -
tor is too high.
E18-01 Overload The power unit was overloaded (unusual
operation from the characteristic). An E01
is likely to appear in this condition.
Let the machine cool down (in case of E01),
switch off and on again.
for details see page 50
E22-03 Undervoltage Startup During startup the bus voltage didn’t
reach the minimum limit of 390V DC.
-check mains and bus voltage
-check wiring between DRV (X6) and
MAPRO (X7)
for details see page 48
E25-01 OCV generator Startup No open circuit voltage could be meas-
ured during startup.
-check for short circuits at the output
sockets
- check wiring of power unit and DC0x (X2)
- check between DC0x (X2) and MAPRO
(X5)
-check LorchNet-Remote
-check torch and central connector
for details see page 51
The start contact at the LorchNet-Remote
interface was active during switching on
of the machine.
E25-02 OCV generator No open circuit voltage could be meas-
ured when switching to MMA or TIG
E27-00 No program or missing process Welding programs are not present or
missing.
reprogram the machine, exchange MAPRO
if necessary
E30-04 Configuration primary The measured bus voltages are not
matching the actual configuration.
-check wiring at X17 of the DRV
- check configuration resistors on DRV
for details see page 55
E30-05 Configuration machine The data of the machine configuration
could not be read or is corrupted.
Switch the machine off and on again, con -
tact Lorch Service if necessary.
E30-06 Configuration software The actual software is not compatible to
the machine hardware.
Re-program the machine with the correct
software.
E30-07 Configuration VRD The VRD voltage setting was changed
(reprogrammed).
This is only a status message in the list of
the last error codes to indicate that the VRD
voltage setting was changed.
E31-04 Communication FPGA-DSP The FPGA doesn’t recoginze any activity
of the DSP.
Switch the machine off and on again, if the
error is permanently, the MAPRO should be
exchanged.
E31-05 Communication primary DSP Malfunction in the communication be-
tween the primary DSP on the DRV and
the DSP of the MAPRO.
- Switch the machine off and on again
- check the flat ribbon cable between
MAPRO and DRV
E31-06 Communication primary DSP Startup When switching on the machine, there
was no signal received by the MAPRO
ffrom the primary DSP (DRV).
E32-01 Overcurrent FPGA A primary input current >80A was meas -
ured.
-check secondary diodes
-check primary modules
-check wiring between DRV (X6) and
MAPRO (X7)
- check the flat ribbon cable between
MAPRO and DRV
for details see page 56
E32-04 Overcurrent IPmax A primary input current >60A was meas -
ured.
E32-02 Timeout When driving the power unit, after some
time a zero-crossing (polarity change) of
the current could not be detected.
-check wiring between DRV (X6) and
MAPRO (X7)
