: The control module detected a massive spike in current, usually because the motor is trying to force its way through a physical restriction. Step-by-Step Fix :
I can provide specific adjustments or parameters tailored exactly to your workshop's layout. Share public link
: Check oil levels daily. Ensure the oil is above the "L" line on the gauge. Change the oil after the first month and every four months thereafter. Secure Connections
Motor failures that persist after checking cable connections.
The Siruba L818FM1 is a high-speed, single-needle, lockstitch machine with an automatic thread trimmer. Its error system is designed to alert operators of mechanical jams, electrical faults, or parameter issues. siruba l818fm1 error list work
Check if the motor encoder connector has fallen off or is loose. Safety Switch Active
If your L818FM1 is equipped with a digital motor control box, errors usually refer to the motor, not the machine head: : Speed control unit or pedal sensor error.
The machine head may be tilted back or the safety switch is damaged/misaligned. Ensure the machine head is properly seated in the table. General Troubleshooting Steps
The is an industrial lockstitch sewing machine designed for light to medium fabrics. Unlike modern fully electronic machines, the L818 series often uses external control boxes or simple direct-drive motors, meaning errors typically manifest as mechanical failures or specific motor controller codes. Common Error Codes (Electronic Control) : The control module detected a massive spike
: Industrial machines require frequent needle changes; always ensure the needle is pushed up as far as it can go in the clamp. How to fix a jammed Industrial Sewing Machine
When components are replaced or sensors misalign, adjusting the internal parameters may be necessary to clear faults.
A valuable diagnostic method for machines experiencing communication issues involves testing the machine's behavior with and without the position sensor connected. If the machine continues to run but cannot detect its position or regulate its speed when the sensor is disconnected, it is highly probable that the primary issue lies with the sensor itself or its associated circuitry.
If you need further help maintaining your sewing equipment, let me know: Ensure the oil is above the "L" line on the gauge
Ensure the machine is not on a circuit with too much load. 6. ERR33 - Air Pressure Low
If the sensor is misaligned, it may need to be readjusted. 2. ERR4 - Limit Error (Feed Limit Error)
