Fan monitoring can be triggered in devices with a power greater than 7.5 kW (eliminated from V5.0 onwards)
Eliminated from:
StateLine / HighLine with firmware version V05.01 or higher
Behaviour of the new version?
This function restriction is eliminated with the above-mentioned firmware version.
Which products are affected?
8400 StateLine / HighLine with a power > 7.5 kW and with FW < 05.01
What happens?
'Fan error' is entered into the Logbook.
When does the problem occur?
In a worst case scenario, the fan monitoring can be triggered causelessly in devices with powers from 7.5 kW.
Possible diagnostics?
Control the fan via fan running noises
Short-term measures / recommendations?
Deactivate response to fan failure (C00566)
Evaluation:
If the fan really fails, the inverter will switch off due to overtemperature after a while of being under load. This will not permanently destroy the inverter.
