EFd 13
The voltage for motor calibration is out of limits
Perform motor calibration (motor plate 2R pressure lever must be open),
replace motor, replace LSTMAG20 PC board Cause:
Remedy:
EFd 14
Fault in the wirefeed system (overcurrent in wirefeeder drive, motor
blocked)
Arrange the hosepack in as straight a line as possible. Check inner liner and
contact tip; check contact pressure on 2-roller drive; possibly remove any
wire entanglements on the motor plate 2R; check motor current in open cir-
cuit (≤1,0A at 10m/min), if motor current is too high replace motor Cause:
Remedy:
EFd 80
Fault in the wirefeed motor (break in circuit)
Check motor plug, replace motor Cause:
Remedy:
EFd 81
Fault in the wirefeed system (overcurrent in wirefeeder drive)
Arrange the hosepack in as straight a line as possible. Check inner liner and
contact tip, check contact pressure on 2-roller drive; observe duty cycle of
the device; check motor current in open circuit (≤1,0A at 10m/min), if motor
current is too high replace motor Cause:
Remedy:
EFd 83
Short circuit in wirefeeder motor or on LSTMAG20 PC board
Unplug motor; start function test; if there is no error EFd 83 replace motor,
otherwise replace LSTMAG20 PC board Cause:
Remedy:
EFd 84
Fault on the PC board, no command is send to the motor
Check 24V motor power supply, replace PC board Cause:
Remedy:
to0<TMP>
Overtemperature on the PC board LSTMAG20 (secondary circuit), <TMP>
is the temperature indicator
Allow power source to cool down, check air filter and clean if necessary,
check that fan is working Cause:
Remedy:
to2<TMP>
Overtemperature on power source secondary circuit, <TMP> is the temper-
ature indicator
Allow power source to cool down, check air filter and clean if necessary,
check that fan is running Cause:
Remedy:
to3<TMP>
Overtemperature on the PC board LSTMAG20 (motor controller), <TMP>
stands for temperature indicator
Allow power source to cool down, check air filter and clean if necessary,
check that fan is working Cause:
Remedy:
to6<TMP>
Overtemperature on the PC board LSTMAG20 (voltage doubler), <TMP> is
the temperature indicator
Allow power source to cool down, check air filter and clean if necessary,
check that fan is working Cause:
Remedy:
