is a high-speed, single-needle lockstitch machine renowned for its precision in handling thin to medium-thick fabrics. However, even the most reliable industrial equipment can encounter technical interruptions. Understanding the 2021-era error codes and troubleshooting protocols is essential for maintaining production efficiency and machine longevity. Understanding Core System Errors
The L818 series remains a staple for workshops due to its balance of speed and durability.
Most "Ex" errors are caused by loose cables at the back of the control box or motor.
Remove sources of electromagnetic noise or check for high-frequency input signal errors. E8 / ERR17 Position detector error
Internal memory error. Often requires turning the machine off and back on after a few minutes. If it persists, the control board may need service. Counter Set to Zero siruba+l818fm1+error+list+2021
Many 2021 units shipped with a more sensitive Hall sensor. After a few months, the magnet on the handwheel weakens or shifts. Re-calibrate using the manual “Needle Positioning” mode (Parameter P-15: Adjust needle up/down angle to 145° and 325° respectively).
: Frequent thread breakage can be caused by incorrect threading, improper tension, or using the wrong type of thread.
The input voltage supply to the control box exceeds the maximum safe threshold, or there is a surge in the power line. Action Steps: Power off the machine immediately.
Likely 2021-specific considerations
The hum of the garment factory was a symphony knew by heart, but today, his lead performer—the Siruba L818F-M1
Proactively managing these core systems will keep your industrial production lines running efficiently while preventing costly component replacements.
: Ensure the synchronizer unit attached to the handwheel hasn't slipped out of position.
Triggered when the machine or motor is physically locked. This may be caused by a bird's nest of thread or an object stuck in the motor pulley. E7 (Communication Error): Understanding Core System Errors The L818 series remains
The incoming voltage is too high. This can damage the control box; use a voltage stabilizer if this persists. 2. Motor & Mechanical Blockage Errors (E3, E4, E6) If the needle stops mid-stitch, look for these codes:
Machine is overloaded, thread is tangled in the hook, or the feed dog is hitting the needle plate. Solution: Turn off the power. Clear any tangled thread in the bobbin area. Check if the feed dog is free to move. Restart the machine. ERR5 – Clamp Position Error (clamp err)
Do not operate the machine without the proper safety shields (eye guards) in place.
