Structural Characteristics
- Standard FSC rack slot modular structure.
- Dual axial fans installed side by side inside module frame.
- Front side air filter for dust filtration.
- Rear monitoring PCB collects fan speed signal and outputs fault alarm.
- Quick locking mechanism enables fast module removal and replacement.
- Airflow direction aligns with FSC rack internal thermal path.
Working Principle 24VDC power supplies dual brushless fans. Both fans rotate simultaneously to generate airflow through rack electronic modules. Tachometer sensors detect rotation speed of each fan independently. If one fan stalls or speed drops below threshold, the monitoring circuit triggers fan fault alarm and sends fault signal to FSC controller. The remaining fan continues cooling operation to maintain rack temperature.
Installation Requirements
- Insert FC-FANWR-24R module into designated fan slot of FSC rack.
- Confirm airflow direction matches FSC rack cooling requirement.
- Complete protective earth connection for module frame.
- Verify fault signal wiring to FSC controller.
- Clean air filter before power energization.
- Perform fan operation and fault simulation test after installation.
Usage Notes
- Cut off module power before removing fan module.
- Clean air filter regularly to avoid airflow blockage.
- Check fan noise and vibration during routine inspection.
- Replace module immediately when fan fault alarm is triggered.
- Do not block air inlet and outlet during system operation.
- Keep cabinet free of oil mist and corrosive gas.
