Troubleshooting guide
code description reason removal
E 00 no program no welding parameters available for selected
material-wire-gas combination (no reasonable
combination) select other material-wire-gas combination
E 01 thermal overload thermal sensor of power unit measures a too high
temperature let machine cool down in standby (*1)
E 02 mains overvoltage mains voltage too high (24V supply > 36V) check mains voltage and control transformer (*2)
E 03 secondary overcurrent welding current is too high check current sensor
E 04 air cooling error Temp. sensor of the power unit detects that the
unit heats up too fast check fan and air fl ow
E 05 cooling system error fl owrate of the cooling liquid is too low (< 0,3 l/
min)
pump is not working
check connectors of fl ow-meter, level of cooling
liquid and fl owrate (*3)
check fuse SI7 (2,5A) on pc-board DP-MAPRO
E 06 secondary overvoltage Master detects output voltage is too high (>100V) check wiring of power unit
E 07 EEProm checksum error no welding program stored or error during rea-
ding from memory switch the machine off and on again, if necessary
transfer the welding programs to machine again
E 08 wire feed / tacho power consumption of wire feed motor too high
no tacho signal
no CAN-Bus connection between pc-board
MAPRO and pc-board DMR blow out torch package with compressed air
check wire feed unit
check wiring of wire feed motor and pc-board
DMR
E 09 error v/a measuring measuring difference between Master and
Process check wiring of current sensor and pc-board DK-
UFI
E 11 remote-control conn. short circuit between remote control cables check remote control and wiring of remote control
socket
E 12 Communication Process Process is not responding to Master switch the machine off and on again
optionally exchange pc-board DP-MAPRO
E 13 Temp. sensor error Temp. sensor is faulty check resistor value and wiring of the sensor
E 14 Op. voltages error supply voltage is too low (24V supply < 17V) check mains voltage and control transformer (*2)
E 16 primary overcurrent
protection1 power consumption of power unti 1 is too high check MOSFETs and pc-board DCDRV
E 18 overload protection safety shutdown to protect electrical components
temp. sensor is disconnected let machine cool down in standby
check temp. sensor
E 20 Overvoltage sec. Process reports a too high output voltage or no
voltage can be measured check wiring of power unit, especially wiring from
output sockets to pc-baord DP-MAPRO
E 21 Output voltage/current external current/voltage or measure-difference
between Master and Process check wiring of current sensor and pc-board DK-
UFI
E 22 Mains undervoltage 1 power unit 1 reports mains voltage too low check mains voltage, mains recti fi er and pc-board
PWRUP
E 23 Mains overvoltage power unit reports mains voltage too high check mains voltage
E 24 Overcurrent protection2 power consumption of power unti 2 is too high check MOSFETs and pc-board DK-DCDRV
E 25 Power module detection Jumper on pc-board DK-DCDRV have been set
wrong check DIP switch on pc-board DK-DCDRV
E27 no program (DSP) invalid material-wire-gas combination selected
welding programs faulty or not available select other material-wire-gas combination
transfer welding programs to machine again
E 30 Mains undervoltage 2 power unit 2 reports mains voltage too low check mains voltage, mains recti fi er and pc-board
PWRUP
E 31 Communication error Master is not responding to Process switch the machine off and on again
optionally exchange pc-board DP-MAPRO
the display only shows
a “?“ the display doesn‘t get any data to show no CAN bus connection between pc-board DMR
and pc-board DP-MAPRO
