Functions of the PFCU

The PFCU is used to monitor the fan box.

The PFCU performs the following functions:

• Monitors the operating status of the fans and indicates the current status of the fan box through the LEDs
• Communicates with the GSCU and reports the working status of the fan box
• Detects the temperature of the fan box and collects temperature data through a temperature sensor
• Provides Pulse-Width Modulation (PWM) control signals for fan speed adjustment
• Reports the operating status and alarms of the fan box through the LEDs
