9 Error, warning and information messages
The DAC
eco
control unit contains three groups of messages that are divided as follows:
Serious error
Turn off the control unit and correct the error.
Eliminate the condition that caused the warning and the control unit will continue to work normally.
Press OK
You can continue to work; only emergency running properties may be available.
The messages are visualised via LED2. The coding is displayed via LED2
flashing every 0.5 seconds. The flashing sequence is then interrupted for two seconds and
repeated.
Error or information description
- Check the tilt sensor on the machine
Low voltage warning (1st threshold)
(mains voltage < 180V AC)
- Check mains voltage
- Stabilise mains voltage
- Use generator
Pedal position is not in position 0
- When switching on the control unit, take foot off
pedal
Sewing motor encoder plug (Sub-D,
9-pin) not connected.
- Insert the encoder lead into the control unit. Use the
correct interface.
- Eliminate sluggish movement in the sewing machine
- Eliminate sluggish movement in the sewing machine
Sewing motor error
Sewing motor plug (AMP) is not
connected.
- Check the connection and if necessary plug in.
- Test sewing motor phases (R= 2.8 Ohm, high-
resistance compared with PE)
- Replace sewing motor
- Replace control unit
Sewing motor insulation error
- Check motor phase and PE for low-resistance
connection
- Replace sewing motor
High voltage error, mains voltage
>290V for some time
- Check mains voltage, if rated voltage exceeded
permanently - stabilise or use generator
EEprom communication error
- Check the connection of the Mach ID
- Turn off the control unit, wait until LEDs are off,
restart
No valid data on external EEprom
- Check the connection of the Mach ID
- Turn off the control unit, wait until LEDs are off,
restart
- Update software
Low voltage failure (2nd threshold)
(mains voltage < 150V AC)
- Check mains voltage
- Stabilise mains voltage
- Use generator
Sewing motor turning in the wrong
direction
- Replace encoder
- Check that the motor plug is in the correct place and
change if necessary
