Hi Jonas Klein, if you want to change how sensitive the separation is, it is best to check the milk separation settings and the udder health settings in Horizon, or contact your Lely advisor because the available adjustments can depend on the A4 setup and software version.

thanks for your reply. So far my robot only separates bloody milk automatically. 

Is there a way to separate milk with e.g. a conductivity higher than 85 automatically?

Dear Jonas Klein, to say kindly probably not. The Astronaut A4 does not support setting a fixed conductivity threshold for automatic milk separation. If you want to change how sensitive the system is, you can review the udder health and milk separation settings in Horizon with your Lely advisor, but you cannot configure a specific conductivity value such as 85 for automatic separation. I could be wrong, but for us it was not possible at least.
