Hi, I have a Ptur in Fault with red led on (processor R) but the other two Ptur are ok. Can I replace the Ptur ko with a new Ptur with turbine power on or is recommendable power off the turbine? The replace is play and play?

Thanks

 

Don't mess with a running machine. Its better to do when the machine is not running. Moreover the new IO Pack might need a download too.
