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 at 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 o󰀨set 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 o󰀨set FPGA The o󰀨set 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 o󰀨 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 Conguration primary The measured bus voltages are not
matching the actual conguration.
- check wiring at X17 of the DRV
- check conguration resistors on DRV
for details see page 55
E30-05 Conguration machine The data of the machine conguration
could not be read or is corrupted.
Switch the machine o󰀨 and on again, con-
tact Lorch Service if necessary.
E30-06 Conguration software The actual software is not compatible to
the machine hardware.
Re-program the machine with the correct
software.
E30-07 Conguration 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 o󰀨 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 o󰀨 and on again
- check the at 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
󰀨rom 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 at 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)
