1What the error means
Fan malfunction. The fan is not working properly, and without cooling, over-temperature and reduced output will follow.
On the display or in the monitoring software it appears as FS 70.
2Possible causes
- Blocked by dust or a foreign object
- Worn bearing
- Fault in the fan's supply circuit
3What to do
- Clean the fan and the heat sinks.
- Check whether it turns freely.
- If it does not run, it needs to be replaced — otherwise overtemperature will follow.
