3. 설정 지침

Follow these steps to set up your DEVMO HW-585 fan controller:

1. 전원 연결: Connect a DC 12V power supply to the blue screw terminal labeled "-12V+" on the board. Ensure correct polarity.
2. 팬 연결: Connect your 4-wire PWM fans to the white headers labeled FAN1, FAN2, and FAN3.
3. 온도 프로브: Connect the included temperature probe to the dedicated white connector on the board. Position the probe in the area where temperature monitoring is required (e.g., near a CPU heatsink).
4. 부저 연결: Connect the buzzer to the connector labeled "BEEP". This will enable audible alarms for fan stall conditions.
5. DIP 스위치 구성: Configure the DIP switches (labeled 1-5) according to your desired operating parameters. Refer to the "Operating Instructions" section for detailed settings.

4. 사용 설명서

The DEVMO HW-585 controller's behavior is configured using the 5-position DIP switch block. Each switch controls a specific function:

딥 스위치 기능:

• TFL (Switch 1): Controls the minimum PWM setting for FAN1.
  
  • 에: FAN1 minimum PWM is 40%.
  • OFF : FAN1 minimum PWM is 20%.
• TP1, TP2 (Switches 2, 3): These switches, used in conjunction with the temperature probe, define the temperature control zones (accelerating temperature and full-speed temperature).
  

  TP1	TP2	Accelerating Temperature	Full Speed Temperature
  끄다	끄다	35도	45도
  ON	끄다	40도	55도
  끄다	ON	50도	70도
  ON	ON	60도	90도

  When the detected temperature is below the accelerating temperature, the fan will operate at its minimum rotation speed. When the temperature exceeds the full-speed temperature, the fan will operate at full speed. Between these two temperatures, the fan speed will gradually increase.
• BF1, BF2 (Switches 4, 5): These switches activate the stall alarm function for FAN1 and FAN2 respectively. If a fan connected to a corresponding open channel (ON) stops rotating, the controller will trigger an alarm with sound (via the buzzer) and light (via an onboard LED). The alarm will automatically clear once the fan resumes rotation.
  
  • 에: Stall alarm enabled for the corresponding fan.
  • OFF : Stall alarm disabled for the corresponding fan.

6. 유지관리

The DEVMO HW-585 fan controller is designed for reliable operation with minimal maintenance. To ensure continued performance:

• 깨끗하게 유지하십시오: Periodically inspect the board for dust accumulation. If necessary, gently clean with a soft brush or compressed air. Ensure power is disconnected before cleaning.
• 연결 확인: Regularly verify that all power, fan, temperature probe, and buzzer connections are secure. Loose connections can lead to intermittent operation or malfunction.
• 환경 조건: Operate the controller within its specified temperature and humidity ranges to prevent damage. Avoid exposure to moisture or extreme temperatures.

7. 문제 해결

If you encounter issues with your DEVMO HW-585 controller, consider the following troubleshooting steps:

• No Fan Movement:
  • Verify the 12V DC power supply is correctly connected and providing power.
  • Ensure fans are properly connected to the FAN headers.
  • Check DIP switch settings (TFL, TP1, TP2) to ensure the fan is not set to a very low minimum speed or a high temperature threshold that has not been met.
  • Test fans directly with a 12V source to confirm they are functional.
• Fan Stall Alarm (Buzzer/LED):
  • If the alarm activates, check the fan connected to the corresponding channel (FAN1 for BF1, FAN2 for BF2).
  • Ensure the fan is not obstructed and can rotate freely.
  • Verify the fan's RPM is above the minimum stall alarm threshold (700-800 rpm).
  • If the alarm is unwanted, set the corresponding BF1 or BF2 DIP switch to OFF.
• Incorrect Temperature Response:
  • Ensure the temperature probe is securely connected and positioned correctly to measure the desired temperature.
  • Review the TP1 and TP2 DIP switch settings to confirm the correct temperature zones are selected.
  • Check the temperature probe for any physical damage.
• 간헐적 작동:
  • 모든 배선을 점검하여 느슨한 연결이나 손상이 없는지 확인하세요.
  • Ensure the power supply is stable and provides sufficient current for all connected fans.
