Heatsink temperature sensor error

¿Qué significa H10 ?

The sensor for detecting the heatsink temperature is indicating undefined values. This prevents accurate monitoring of the heatsink's thermal status, potentially leading to overheating if not addressed.

• Failure of the heatsink temperature sensor (e.g., NTC thermistor) itself, providing an out-of-range resistance value.
• Broken or loose wiring connection between the heatsink temperature sensor and the control board.
• Corrupted input or processing circuit on the control board for the temperature sensor signal.
• External electromagnetic interference (EMI) affecting the low-voltage sensor signal wiring.

1. 1

   Completely power cycle the drive (disconnect all power, wait 5 minutes) to reset the internal monitoring circuits.

2. 2

   Using a multimeter, measure the resistance of the heatsink temperature sensor directly at its terminals (e.g., X12.1, X12.2) and compare with the manufacturer's specified resistance-temperature curve (e.g., 10kOhm at 25°C).

3. 3

   Inspect the wiring from the heatsink temperature sensor to the control board for any breaks, loose connections, or signs of heat damage.

4. 4

   Check for any significant sources of EMI near the drive that could be affecting sensor wiring. Ensure proper grounding of the drive chassis and shielded cabling.

5. 5

   If available, use diagnostic software to monitor the raw temperature sensor reading to determine if the reported value is consistently out of range or erratic.
