Need assistance with "Bed Wash" VTC250D/50 with a Mazatrol Matrix Nexus 2

Hi folks!

After spending a career in front of Fanuc based machines, I am now tasked with learning the Mazak. I have a few questions and will break them up into separate entries here. First off, the machine is a VTC250D/50 and the controller is a Mazatrol Matrix Nexus 2. I attended Mazak’s school in Cincinatti, but it was very very superficial.

My last question (for tonight LOL) is about the "bed wash". The machine is only 3 months old. When it was first installed, I could have sworn that I saw that big "line loc" coolant nozzle behind the bed gush coolant to keep the area behind the bed free of chips, etc. I noticed today that it is no longer flowing coolant. We've had some work done by Mazak repair and I'm not sure if they turned something off and didn't turn it back on, or if an operator (deliberately or not) has turned something off.

I understand that that is supposed to be automatic when the machine is running. Is there a manual valve, or electronic switch somewhere that I am missing? Maybe a parameter?

Many thanks!

Mark
