8400 StateLine, HighLine and TopLine: FW version = 13.00.00.00
Response of the new version?
Fan ON at T=60°C, fan OFF at T=55° instead of previously T=59°
Which products are affected?
8400 StateLine, HighLine and TopLine: FW version ≤ 13.00.00.00
What happens?
If the internal device temperature is around T=60°, the internal fan and the heatsink fan apparently keep switching on and off.
When does the problem occur?
Every time the internal device temperature reaches T=60°, the fans are switched on and already switch off at T=59°.
Diagnostics options?
The "Fan on/off" status can be diagnosed on the basis of the noise response.
Short-term measures/recommendations?
None.
Evaluation:
Toggling between the states of fan ON and fan OFF does not have a negative impact on the cooling response. The functionality of the inverter is not influenced.
