1. Immediately Disconnect Power and Activate Emergency Stop Protection
Upon detecting an overload alarm (OL1/OL2), abnormal temperature rise, or severe vibration, immediately press the emergency stop button to disconnect the main power supply.
This prevents motor burnout, transmission system damage, or electrical component breakdown, avoiding further damage.
2. Quickly Troubleshoot the Root Cause of the Overload
🔍 Mechanical Inspection (5–10 minutes)
Is the Load Exceeding Limits?: Remove excess fabric to ensure it does not exceed the equipment's rated capacity (e.g., 250kg for Hongshun HSCW-0071).
Is the Transmission System Blocked?: Manually rotate the machine to check the rollers, chains, and bearings for flexibility, and remove any foreign objects or lint clogging them.
Circulation Pump and Nozzles: Clean the filters and nozzles to ensure smooth dye liquor flow.
🌡️ Electrical and Temperature Control Testing (5 minutes)
Use an infrared thermometer to check the motor casing temperature. If it exceeds 70℃, cool it down to below 50℃.
Use a multimeter to initially measure the motor insulation resistance. If it is below 0.5MΩ, there may be moisture or winding aging, requiring professional handling.
3. Natural Cooling and System Reset
Cooling Time Control:
Mild Overload: Cooling can be completed within 30 minutes after power failure;
Severe Overheating: Requires 1–2 hours of natural heat dissipation. Forced air cooling or water spraying is prohibited.
After cooling, clear the overload alarm code on the PLC or touchscreen interface and reset the control system.
4. Phased Trial Run, Gradual Loading
10-minute no-load trial run: Observe whether the current, sound, and vibration are normal.
Phased load recovery to restore production: First, load 50% and run for 15 minutes; then increase to 80% load and run for another 15 minutes; after confirming there are no abnormalities, restore to 100% full load operation.
