code designation reason removal
E 08 M04 Motor 2 overcurrent
(only at DMRPP)
PushPull-motor draws too much cur-
rent
– check PushPull-torch and -motor
– check motor current (*4)
M05 Tachometer motor 1
(only at DMRPP)
– tacho signal of wire feed motor is
missing or bad
– wire feed motor is not running
– check wiring of the tacho
– check wiring of the motor, exchange
motor if necessary
M06 Tachometer motor 2
(only at DMRPP)
– tacho signal of PushPull motor is
missing or bad
– PushPull motor is not running
– wrong PushPull torch type selected
– wrong PushPull torch type selected
– check PushPull torch and wiring of
the PushPull
M07 EEProm access
(only at DMRPP)
no access to EEProm memory (hard-
ware)
switch the machine off and on again,
exchange pc-board DMRPP if neces-
sary
M08 EEProm checksum
(only at DMRPP)
data in EEProm memory wrong/cor-
rupted (software)
– switch the machine off and on again
– re-program the DMRPP
– exchange pc-board DMRPP if neces-
sary
M09 Remote-control conn.
(only at DMRPP)
start contact (remote control interface
DMRPP) was closed during switching
on the machine
check remote control and the wiring of
the remote control socket/interface
M10 Torch connection
(only at DMRPP)
– start button (torch trigger switch)
was pressed during switching on
the machine
– too high voltage on the torch button
wires (short circuit between torch
button wires to welding potential or
motor wires.)
check torch and torch control wires
M12 Calibration error
(only at DMRPP)
calibration of the PushPull torch was
unsuccessful
– check torch and torch control wires
– check pressure lever of wire feed
unit and of PushPull torch
– insert the wire
M13 Machine ID unknown
(only at DMRPP)
the internal power source id couldn’t
be recognized
(unknown power source)
– switch the machine off and on again
– reprogram (flash) the DMRPP or ex-
change it if necessary
M14 Thermal overload
(only at DMRPP)
the temperature of the lower pc-
board DMRPP-P is too high
let the pc-board cool down when the
machine is switched off
M15 Wire end detection
(only at DMRPP)
wire-end sensor has detected no wire
(wire spool empty)
!!! this error message is not active/
implemented !!!
at all sub messages Mxx of the DMRPP: see also hardware details on page 56
E 09 Error v/a measuring – too high output signal from current
sensor VAC
– voltage measuring difference be-
tween Master and Process
– check current sensor VAC and its
wiring
– check pc-board DP-UFI-BO and its
wiring
see page 50 and page 55 for
details
E 11 Remote-control conn. – start contact was closed during
switching on the machine
– short circuit between remote con-
trol cables
check remote control and wiring of
remote control socket
see page 58 for details
E 12 Communication Process Process is not responding to Master switch the machine off and on again,
exchange pc-board MAPRO if neces-
sary
