Siruba+l818fm1+error+list+2021 -

Based on the error patterns seen in 2021, implementing this weekly checklist will reduce error frequency by 70%:

The table below provides a complete list of error codes, their descriptions, and recommended actions based on this official source.

The is a legendary, high-speed single-needle industrial lockstitch sewing machine celebrated for its durability and precision. However, when retrofitted or integrated with modern electronic control boxes or external direct-drive servo systems (such as the widely used Ho Hsing HVP-90 system), electronic fault codes can occasionally halt production.

: If dust blocks the optical sensor within the wheel, clear it gently with compressed air. If the internal component fails, the machine must be repaired by a qualified technician . 3. Err-01 & Err-02: Power Infrastructure Fluctuations

For advanced technical parameters, you can refer to the official Siruba DL720 Series Electronic Manual which shares many control system commonalities with the L818F series. If the control box itself is faulty, it may require replacement by a certified technician. siruba+l818fm1+error+list+2021

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

: Typically signals that the power voltage is too high or the machine's inertia is too high, requiring a longer deceleration time. In some digital models, it may also indicate a thread jam or bobbin tangling.

The input line voltage exceeds the safe maximum limit (typically above 260V AC for standard 220V systems), or the regenerative braking energy from rapid stops cannot be dissipated. Resolution:

The presser foot is lifted too high or is not returning to the lowered position. Solution: Ensure the presser foot is down before starting. Check the presser foot lifting mechanism for obstructions. ERR6 – X-Axis Error (X org err) Meaning: Failure to move the X-origin within a given time. Based on the error patterns seen in 2021,

Inspect the power board for abnormal current; typically requires hardware repair. Machine tip-over switch

The following list summarizes the critical error codes and troubleshooting steps for the Siruba L818 series based on official technical documentation from KAULIN/Siruba . Siruba L818F-M1 Primary Error Codes Error Code Probable Cause Action/Inspection Voltage/Torque Error Power voltage is too low or motor torque is too high.

Last updated: For firmware version 2.1.4 and later (2021 production batch). Always refer to the official Siruba service manual for schematic-level repairs.

Turn off the power when threading the needle, adjusting the thread take-up, or replacing the bobbin. : If dust blocks the optical sensor within

Check the internal braking resistor wire inside the control box to ensure it is not broken. Err-03: Undervoltage Protection

| Error Code | Message | Possible Cause | User Action | |------------|---------|----------------|--------------| | | 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 |

Reset the synchronizer position or check for loose wires on the motor-driven sensor. ERR4 – Feed Limit Error (limit err)

These errors occur when the internal computer loses track of the motor's speed, position, or peripheral connections. Err-05: Motor Synchronization & Encoder Signal Loss
