Siruba L818FM1 Error List 2021: The Complete Troubleshooting Guide for Industrial Overlock Machines

Thread Breakage (E-01)

  1. Check thread tension: Ensure thread tension is set correctly according to the machine's manual.
  2. Inspect thread guides: Clean and lubricate thread guides, and replace any worn or damaged components.
  3. Verify thread routing: Ensure thread is routed correctly through the machine's thread guides and take-up levers.

1. Error Code Table (common codes for 2021 firmware)

| Error Code | Message | Possible Cause | User Action | |------------|---------|----------------|--------------| | E-01 | Motor overload | Thread tangled, material jam | Remove fabric/thread, restart | | E-03 | Needle position sensor error | Sensor dirty/misaligned | Clean sensor, recalibrate | | E-05 | Foot lift solenoid failure | Solenoid stuck or disconnected | Check wiring, replace solenoid | | E-07 | Thread trimmer error | Knife stuck, magnet switch fault | Clean trimmer mechanism | | E-08 | Low voltage (under 180V) | Power supply unstable | Check mains voltage | | E-10 | Main motor encoder fault | Encoder disconnected/damaged | Replace encoder board | | E-12 | Control panel communication lost | Cable loose or panel faulty | Reconnect panel cable | | E-15 | Overcurrent | Short in motor or driver | Cycle power; if persists, service |

Needle Breakage (E-02)

  1. Check needle alignment: Ensure needles are properly aligned and seated in the needle bar.
  2. Inspect needle condition: Replace damaged or worn needles with new ones.
  3. Adjust needle size: Verify needle size and type are suitable for the fabric being sewn.

1. E-030 (Digital Tension Motor Limit Error)

The 2021 model introduced a digital stepper motor for thread tension. Dust from high-speed overlocking (especially on denim or canvas) jams the motor. Fix: Weekly cleaning of the tension unit with a brush and setting P-65 to “2” to increase tolerance margin. siruba+l818fm1+error+list+2021

Siruba L818Fm1 Error Code List (Applicable to 2021 Firmware)

| Error Code | Meaning | Likely Cause & Solution | | :--- | :--- | :--- | | E-01 | Machine head locked / overload | Thread tangled in hook, foreign object in rotary hook, or mechanical seizure. Turn off power, clean hook area, and check for free rotation. | | E-02 | Motor position signal error | Faulty synchronizer or encoder. Check the position sensor near the handwheel. | | E-03 | Overvoltage (power supply) | AC input voltage too high. Use a voltage regulator. | | E-04 | Undervoltage | AC input voltage too low. Check power source and cables. | | E-05 | Overcurrent | Motor short circuit or driver board failure. Stop immediately; service required. | | E-06 | Motor overspeed | Control board failure. Turn off machine, restart. If persists, replace control box. | | E-07 | EEPROM (memory) error | Settings corrupted. Reset to factory defaults via panel (see manual). | | E-08 | Communication error (panel to control box) | Loose flat cable between panel and main box. Reconnect securely. | | E-09 | Needle up/down position not found | Magnet on handwheel missing or sensor faulty. | | E-10 | Presser foot lift motor error (if equipped) | Foot lift solenoid stuck or jammed. | | E-11 | Thread trimmer solenoid error | Trimmer stuck or solenoid coil open circuit. | | E-12 | Winding stop sensor error | Bobbin winder mechanism faulty or sensor disconnected. | Siruba L818FM1 Error List 2021: The Complete Troubleshooting
