1. Immediately Disconnect Power and Activate Safety Protection
If an overload alarm is detected (e.g., PLC displays "Overload," driver reports OL1/OL2) or abnormal temperature rise/vibration, press the emergency stop button to disconnect the main power supply.
Do not force a restart to prevent motor burnout or damage to transmission components.
2. Investigate the Cause of the Overload and Address it Accordingly
🔧 Mechanical System Inspection
Check for overloading: Remove excess fabric to ensure it does not exceed the equipment's rated capacity (e.g., maximum 250kg for the HSCW-0071 model).
Check if the drive chain is too tight, if the bearings are stuck, or if the rollers are blocked by foreign objects. Manually rotate the machine to confirm smooth rotation.
Check if the circulating pump is clogged, if the filter is accumulated scale, and clean foreign objects from the nozzles and pipelines.
🌡️ Electrical and Temperature Control System Testing
Use an infrared thermometer to check the temperature of the motor and reducer casing. If it exceeds 70℃, allow it to cool naturally to below 50℃ before resuming operation.
Measure the motor insulation resistance with a multimeter. If it is below 0.5MΩ, the windings may be damp or aged, requiring professional repair.
3. Reset the System and Gradually Restore Operation
After the equipment has cooled down and the fault has been eliminated, reconnect the power.
Clear the overload alarm code on the PLC or touchscreen interface and reset the control system.
Run the system under no-load for 10 minutes and observe whether the current, vibration, and sound are normal.
After confirming that there are no abnormalities, gradually restore production by loading the fabric in stages: 50% → 80% → 100%.
