While the M1 variant is a general-purpose model, specific sub-classes like the L818F-NM1 include a sleeve platen for working on tubular areas like cuffs and hems. Common Error Codes & Troubleshooting
Inspect the mechanical linkages connected to the trimming knife under the needle plate. Ensure they move freely.
Turn off the power, manually rotate the handwheel to make sure the needle is moving freely, and ensure the needle is in the upper position. Restart the machine. If the problem persists, check the needle position sensor connection on the motor. 2. ERR 4 - Limit Error (Feed Limit)
Wiring for the thread trimmer or foot lifter solenoid is damaged. Check for short circuits. 12V Power Failure
While some errors are unavoidable, many can be prevented with regular care. Keeping your L818FM1 in top condition is the most effective way to avoid the frustration of unexpected downtimes. This involves several key practices. First, perform a daily check of the . Always run the machine for a few minutes to circulate the oil before you begin working at full speed. Second, keep the machine clean. Regularly remove lint and thread debris, paying special attention to the bobbin case area and around the sensors . Dirty sensors are a common cause of detection errors. Finally, listen to your machine. Unusual noises or a feeling of resistance when turning the handwheel are early signs of mechanical trouble. Addressing these symptoms immediately can prevent major errors like main motor overload . siruba+l818fm1+error+list+2021
: Check your power voltage and ensure the machine head isn't jammed or short-circuited. E2: High Power Voltage or Excess Inertia
Below is a detailed error list and troubleshooting guide applicable to the Siruba L818FM1 electronic servo system.
The printed on your control box (e.g., Ho Hsing, Qixing)
Excessive current is flowing, usually caused by severe mechanical resistance or an electrical short within the motor. Troubleshooting: While the M1 variant is a general-purpose model,
Trace the solenoid cables back to the control box to ensure secure connections. Mechanical Troubleshooting and Maintenance Protocols
The machine isn't receiving enough power. Check if you have too many machines on one circuit or if your power supply is unstable.
Verify that multiple high-draw machines are not sharing a single, overloaded extension cord or circuit breaker.
The automatic presser foot lifter sensor or the auto-lifter solenoid is drawing unusual current, or the analog pedal sensor is uncalibrated. Resolution: Turn off the power, manually rotate the handwheel
Most error codes arise from preventable mechanical or electrical issues. Implement these maintenance practices to minimize disruptions:
: Turn off the machine, unplug it from the wall, wait 30 seconds, and restart it to clear temporary glitches.
Ensure that cables running under the table oil pan are clamped away from moving linkages. Vibrations can chafe wire insulation, creating intermittent grounds that display as communication or encoder failures.
