Remedy

 

 

 

1.

Turn off the power and then back on again.

 

 

E-55

Stitch no. error (Exceeds 700 stitches.)

 

* The zigzag pitch, front tack pitch and rear tack pitch will

 

 

 

be automatically doubled and the error will be cleared.

 

 

 

 

2.

If an error still occurs after 1. is carried out, turn off the

 

 

 

 

 

power and initialize the parameter settings.

 

 

E-59

Sewing data error

Turn off the power and initialize the parameter settings.

 

 

 

 

Turn off the power.

 

 

 

 

1.

Turn the pulley by hand and check if the upper shaft locks

 

 

E-62

Needle up error during operation

 

or not.

 

 

2.

If an error still occurs after 1. is carried out, check that

 

 

 

 

 

 

 

 

 

connector P3 on the main P.C. board is properly

 

 

 

 

 

connected.

 

 

 

 

1.

Turn off the power.

 

 

 

 

2.

Turn the pulley by hand and check if the upper shaft locks

 

 

E-63

Needle down error during operation

 

or not.

 

 

3.

If an error still occurs after 1. is carried out, check that

 

 

 

 

 

 

 

 

 

connector P3 on the main P.C. board is properly

 

 

 

 

 

connected.

 

 

 

 

1.

Turn off the power.

 

 

 

 

2.

Turn the pulley by hand and check if the upper shaft locks

 

 

E-64

Timing signal error during operation

 

or not.

 

 

3.

If an error still occurs after 1. is carried out, check that

 

 

 

 

 

 

 

 

 

connector P3 on the main P.C. board is properly

 

 

 

 

 

connected.

 

 

 

 

1.

Turn off the power.

3.

Check that the pins of machine motor harness connector

 

 

 

 

 

CN7 are inserted correctly.

 

 

E-74

EEPROM error

Turn off the power and replace the main P.C. board.

 

 

 

 

1.

Turn off the power.

 

 

E-80

Communication ready error

2.

Check that there is data in the main circuit board ROM.

 

 

3. Check that the ROM chips of the main P.C. board are

 

 

 

 

 

properly connected. (Check position, orientation, lead

 

 

 

 

 

clinching.)

 

 

 

 

1.

Turn off the power.

 

 

E-81

Communication error

2.

Check that there is data in the main circuit board ROM.

 

 

3. Check that the ROM chips of the main P.C. board are

 

 

 

 

 

properly connected. (Check position, orientation, lead

 

 

 

 

 

clinching.)

 

 

 

 

1.

Turn off the power.

 

 

 

 

2.

Turn the pulley by hand and check if the upper shaft locks

 

 

 

 

 

or not.

 

 

E-90
