14. TABLE OF ERROR CODES 14. TABLE OF ERROR CODES DANGER Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall outlet before opening the face plate of the control box. Touching areas where high voltages are present can result in severe injury. If a malfunction should occur with the sewing machine, a buzzer will sound and an error code will appear in the display window. Follow the remedy procedure to eliminate the cause of the problem. Code E-13 E-20 E-21 Cause Machine specification select connector is not connected properly. Problem with machine motor stopping, or synchronizer connection error. Machine motor operation error. Remedy Turn off the power and check if connectors P3 is disconnected. Turn off the power, and then turn the machine pulley to check if the machine has locked up. Check the synchronizer connection. Check if connectors P11, P12 and P13 are disconnected. Turn off the power and check the ground wire connection. E-30 E-31 Data is outside possible sewing area due to enlargement ratio setting. Stitch pattern data overlaps the sewing area when area limiting is active. Press the RESET switch, and then set the enlargement ratio again. Press the RESET switch, and then reset the memory switches "30" and "31" or enlargement ratio. E-32 The data format of the user program (% or After changing the setting of DIP switch A-6, clear mm) does not match the setting of DIP all memory settings. (Refer to "10-16. Clearing all switch A-6. memory settings".) E-40 Length of a stitch exceeds 10 mm. E-41 Abnormality in the sewing data. E-42 Invalid program number specified. Press the RESET switch, and then set the enlargement ratio again. If programming a new sewing data, repeat the procedure from the beginning. Press the RESET switch and specify a correct number.
