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 tem-
perature
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 pc-board LSW
E 04
air cooling error
Temp. sensor of the power unit detects that the unit
heats up too fast
check fan and air hardening lime
E 05
cooling system error
flowrate of the cooling liquid is too low (< 0,3 l/min)
pump is not working
check connectors of flow-meter, level of cooling liquid and
flowrate (*3)
check fuse SI7 (2,5A) on pc-board DP-MAPRO
E 06
secondary overvoltage
Master detects output voltage is too high
exchange power unit
E 07
EEProm checksum error
no welding program stored or error during reading from
memory
transfer 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 MAPRO and 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 pc-board LSW and pc-board DK-UFI
E 10
torch socket / cable
short circuit of torch control cables or between torch
switch wires and welding potential
check torch control cables and torch interface
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 defective
check resistor value and wiring of the sensor
E 14
Op. voltages error
supply voltage is too low (< 17V)
check mains voltage and control transformer (*2)
E 16
primary overcurrent
protection1
power consumption of power unti 1 is too high
exchange power unit
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
exchange power unit
E 21
Output voltage/current
external current/voltage or measure-difference between
Master and Process
exchange power unit
E 22
Mains undervoltage 1
power unit 1 reports mains voltage too low
check mains voltage and mains rectifier
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
exchange power unit
E 25
Power module detection
Jumper on pc-board DK-DCDRV have been set wrong
check junper J1, J2 on pc-board DK-DCDRV
E27
no program (DSP)
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 and mains rectifier
E 31
Communication error
Master is not responding to Process
switch the machine off and on again
optionally exchange pc-board DP-MAPRO
