Error
code
Explanation Description of possible fault
E11 Processor interference The processor experiences interference, gen-
erates errors and needs to be reset. Comes
from interference from the mains or other
disruptive equipment. Try resetting the elec-
tronics by keeping the RESET button pressed
for two seconds.
E13
Restart protection tripped Operating fault when starting up the machine.
Check the starting operation in the manual.
The Start/Stop knob must be in the position
"Stop" before the key is turned.
E14
Earth fault Earth fault on motor side. May be due to
jammed or damaged motor cable or motor
breakdown. Check the motor and its connec-
tions.
E15 Overvoltage If the mains voltage (volts) is higher than per-
mitted, the converter is disconnected. Occurs
rarely.
E16 Mains undervoltage Main voltage (volts) is too low for the time
being. May be due to lightning or a loose
contact in the cables. Could occur if someone
connected to the mains is using a powerful
welder. Check the cables and connections.
E21 Overheating Temperature too high in the electronics. See
item E 08. May also be due to having poor
mains voltage and the current being too high
which generates heat in the electronics. Venti-
late the cabinet and turn the machine off for a
while with the door open.
E24
Phase fault One of the incoming phases is missing.
Check the fuses, cables and connections.
8888 Processor failure Contact service if this is the case. The con-
verter must be reset.
