Remedy Turn off the power and check. Turn off the power and check. An operation panel switch was depressed Turn off the power and check the operation panel. when the power was turned on. Check that all panel cords are normal. Abnormal drop in power supply voltage, or power was turned on again immediately after it was turned off. Turn off the power and check the input voltage. After turning off the power, wait 3 seconds or more before turning it on again. (Refer to "10-13. Checking the input voltage".) Abnormal rise in power supply voltage. Turn off the power and check the input voltage. (Refer to "10-13. Checking the input voltage".) Home position cannot be detected (malfunction of home position sensor), or malfunction of power supply circuit board. Turn off the power and check the connection of home position sensor connector P1. You tried to change the program number Press the RESET switch. Set DIP switch A-8 to OFF when DIP switch A-8 was set to ON. before trying to change the program number. No sewing data available. Replace the PROM with one which contains sewing data. Heat sink of control circuit board is abnormally hot. Turn off the power and clean the air intake port of the box. Malfunction of EEPROM (malfunction of main circuit board). Turn off the power, and turn it back on. If the error continually occurs, contact a qualified service technician. Corrupted EEPROM data, or main PROM version has been upgraded. Press the RESET switch to reset the error. However, the data (memory switches, display and user programs) will be reset to the backup data or initialized. Corrupted EEPROM control information data. Press the RESET switch to reset the error. However, the data (memory switches, display and user programs) will all be initialized. E-F0 E-F1 E-F2 Solenoid short-circuit (malfunction of main circuit board), or power relay is not operating (malfunction of power supply circuit board). Turn off the power and contact a qualified service technician. Bad connection in cable between power Turn off the power and check if connectors P16 is supply circuit board and main circuit board. disconnected. Abnormal current detected in power supply circuit board. Turn off the power and contact a qualified service technician. s Errors generated when optional equipment is connected Code Cause Remedy E-14 Thread breakage detected. Turn the EMERGENCY STOP switch clockwise to release the lock, and then press the RESET switch to reset the error. You can then press the BOBBIN. WIND switch to repeat the sewing. E-15 Air pressure drop error. Turn off the power and check. If drops in air pressure are not being detected, clear all memory settings and then set the memo-1d switch to OFF. E-16 Bobbin thread sensor mechanism error Turn off the power and check. If the bobbin thread amount is not being detected, clear all memory settings and then set the memo-24 switch to OFF.
