Siruba+l818fm1+error+list+2021 ((better))

Introduction The Siruba L818FM1 is a high-speed, direct-drive, four-thread overlock sewing machine widely used in industrial garment manufacturing. Known for its energy efficiency and low noise, it is a staple in many production floors. However, like any sophisticated electromechanical device, it is prone to specific error codes—especially models manufactured or updated in 2021.

If you are seeing a blinking light or an alphanumeric code on your Siruba L818FM1’s control panel, you are likely dealing with a system error. This is your definitive guide to diagnosing, understanding, and resolving the most common fault codes reported for this specific model year. siruba+l818fm1+error+list+2021

| Error Code | Display Message | Probable Cause | Recommended Solution | |------------|----------------|----------------|----------------------| | | Motor Overload | Servo motor current exceeds 150% of rated value; fabric jamming under presser foot. | Remove fabric jam. Reset the machine. Check for thread entanglement in the hook area. | | E-005 | Encoder Signal Loss | Loose connection between motor encoder and main PCB (Printed Circuit Board). | Inspect encoder cable (CN7 connector). Re-seat the connector. Replace encoder if damaged. | | E-007 | Needle Up/Down Position Error | Needle positioning sensor (magnetic or photoelectric) is dirty or misaligned after 2021 firmware update. | Clean sensor area with compressed air. Run the “Needle Position Auto-Tuning” from the hidden service menu (Press and hold P + S for 5 sec). | | E-010 | Communication Error (Panel to CPU) | Loose ribbon cable between control panel and main control box. Common after vibration. | Turn off power. Remove and reattach the flat ribbon cable. Check for bent pins. | | E-012 | Low Voltage (Under-voltage) | AC input voltage drops below 180V. Brownout condition. | Use a voltage stabilizer. Check wall outlet (should be 200-240V). Do not share circuit with heavy machinery. | | E-015 | Over-voltage | AC input exceeds 260V or regenerative voltage from motor braking is too high. | Install a line reactor or surge protector. Check for faulty brake resistor (40-50 ohms). | | E-018 | Thread Trimmer Solenoid Jam | Solenoid for automatic thread trimmer fails to retract within 0.3 seconds. | Lubricate trimmer mechanism with silicone oil. Check solenoid coil resistance (should be 25-30 ohms). | | E-021 | Presser Foot Lift Solenoid Error | Presser foot lifter solenoid stuck or open circuit. | Manually lift presser foot to check mechanical binding. Test solenoid voltage (24VDC). Replace solenoid. | | E-030 | Digital Tension Motor Limit Error (2021 specific) | The tension control stepper motor over-rotated or hit a physical stop due to thread dust buildup. | Clean thread tension disks. Run “Tension Calibration” from panel: Parameter P-65->1, then confirm. | | E-033 | Main PCB Overheat | Internal temperature of control box exceeds 85°C (185°F). | Clean ventilation fan filter. Move machine away from heat source (steam iron stations). Allow 30 min cool down. | | E-040 | Synchronizer Signal Fault | Timing belt between upper shaft and synchronizer has slipped or broken. | Remove top cover. Check synchronizer belt tension. Replace belt (Part# SIR-818-BT). | | E-045 | Safety Switch Activated | Looper cover or front safety door is open while machine is running. | Close all safety covers. Check magnetic reed switch continuity. Bypass only for testing. | | E-050 | EEPROM Data Corruption | Factory settings lost due to electrical spike or firmware glitch. | Reset to factory defaults: Power off, then press and hold “RESET” + “S” while turning on. Re-enter all P-values. | | E-099 | General System Fault | Multiple conflicting errors. Often a dying main capacitor on the power board. | Call certified Siruba technician. Replace main filter capacitor (450V, 220µF). | How to Access Error History on the L818FM1 (2021 Panel) Unlike older models, the 2021 L818FM1 stores the last 10 errors in non-volatile memory. This is crucial for intermittent faults. If you are seeing a blinking light or

Understanding these codes is critical because ignoring them can lead to thread breakage, needle damage, motor failure, or even total shutdown of your production line. In 2021, Siruba released a firmware update (v2.1.4) for the L818FM1 series, which introduced new error codes related to the digital tension control system and the servo motor encoder. While earlier models had simpler codes (e.g., Er01, Er02), the 2021 version includes more granular warnings for preventative maintenance. Therefore, if you own a machine manufactured or upgraded in 2021, this list is specifically tailored to your control panel’s logic.

Each entry includes the error code , display message , probable cause , and recommended solution . | Remove fabric jam

If you see or E-005 persistently after re-seating cables, call an authorized Siruba service center. Attempting to replace the main PCB without static protection can permanently damage the machine. Conclusion: Mastering the Siruba L818FM1 in 2021 The Siruba L818FM1 remains one of the most reliable industrial overlockers, but the 2021 models introduced a new layer of digital diagnostics. By understanding this siruba+l818fm1+error+list+2021 , you can reduce unplanned downtime from hours to minutes.
