14 Error-, warning- and info-messages
The control DAC
basic
or DAC
classic
has got three groups of messages. In the following table this three groups are
described.
Error
Switch off the control and eliminate the problem .
Eliminate the state that caused to the warning. The control will normally worked.
Information push the OK-button
Further working should be possible. It could be that only only emergency run features are
possible.
Fehler- bzw. Info- Beschreibung
Sewing motor encoder plug (Sub-D,
9 pin) not connected.
- Insert the encoder lead into the control unit. Use the
right interface.
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
Sewing motor turning in the wrong
direction
- Replace encoder
- Check that the motor plug is in the right place and
change if necessary
- Check wiring in the machine distributor and change if
necessary
- Test motor phases and check for value
-Eliminate sluggish movement in the sewing machine
- Change the Encoder
- Reset the control unit
- Check the machine sub class ( t 51 04)
Errors in the reference movement
- Change the encoder
- Eliminate sluggish movement in the sewing machine
Excess sewing motor current,
internal current increase >25A
- Eliminate sluggish movement in the sewing machine
Position not reached (for thread
cutting, turning round etc. )
- Check controller settings and if necessary change,
mechanical changes to the machines, e.g. thread
cutter setting, belt tension etc.)
- Check the thread lever up position (Position 2)
AC RDY timeout , intermediate
circuit voltage has not reached the
defined threshold in the given time.
- Check mains voltage
- If mains voltage OK, replace control unit
High voltage error, mains voltage
>290V for some time
- Check mains voltage, if rated voltage exceeded
permanently - stabilise or use generator
Low voltage failure (2nd threshold)
(mains voltage < 150V AC)
- Check mains voltage
- Stabilise mains voltage
- Use generator
