Operating Instructions 967 - 02.0 - 11/2016 119
2203 DA stepper card 2 step
losses
• Check for stiff movement
2255 DA stepper card 2 overload • Check for stiff movement
3100 AC-RDY timeout,
intermediate circuit voltage
did not reach the defined
threshold in the specified
time
• Check the mains voltage
• If the mains voltage is OK,
replace the control
3101 High voltage fault, mains
voltage, longer duration
>290 V
• Check mains voltage, if
nominal voltage is
continuously exceeded:
stabilize it or use a
generator
3102 Low voltage failure
(2
nd
threshold) (mains
voltage <150 V AC)
• Check the mains voltage
• Stabilize the mains voltage
• Use generator
3105 U24 V short circuit • Disconnect 37-pin plug;
if error persists, replace
control
• Test inputs/outputs for
24 V short circuit
3106
U24 V (I
2
T) overload
• One or several magnets
defective
3107 Pedal not connected • Connect analog pedal
3109 Operation lock • Check tilt sensor on
machine
6353 Internal EEprom
communication error
• Switch off the control, wait
until the LEDs are off and
then switch on again
