🔴 ALARM-02 on NikMann edgebanders

Any of the asynchronous motrs is overheated!

🔍 What Does ALARM-02 Mean?

When ALARM-02 is triggered on NikMann edgebanders, it means that a motor used in one of the processing units—such as the pre-milling, glue spreading, end trimming, corner rounding, or buffing units has reached a temperature above the safe operating threshold. This is usually caused by overload, insufficient cooling, poor ventilation, or mechanical resistance within the motor.

Asynchronous motors are widely used in NikMann machines due to their reliability and efficiency. However, if these motors operate under stress or for prolonged periods without rest, they can overheat. To prevent permanent damage, the system uses thermal sensors (often PTC thermistors) to monitor motor temperature in real time.

🖥 What Happens on the HMI?

If you are on the HOME SCREEN when ALARM-02 is triggered, the HMI (Human-Machine Interface) will automatically switch to the ALARMS SCREEN. This screen provides:

If you are not on the HOME screen, you can manually access the alarm status by navigating to the “ALARMS” screen from the main menu.

⚠️ Causes of Overheating

Common reasons for asynchronous motor overheating include:


✅ Troubleshooting ALARM-02

  1. Shut Down the Machine Safely

    • Turn off the main power and wait for all moving parts to stop.

  2. Let the Motor Cool

    • Wait 15–30 minutes to allow the affected motor to cool naturally.

  3. Inspect Cooling Fans and Vents

    • Ensure air inlets and cooling fans are clean and functioning properly.

  4. Check for Mechanical Resistance

    • Inspect moving components of the motor (e.g., belts, pulleys, cutter heads) for binding or debris.

  5. Restart the Machine

    • Once everything is clean and the motor is cool, power on the machine.

  6. Reset the Alarm

    • Go to the ALARMS screen and follow the instructions to reset ALARM-02.
