[labnetwork] Fw: Implementing Lock-out/Logins on AJA Phase II J sputter system

[Shepard, Jeremiah J]

We interlock out PVD Sputtering systems via the Process Cooling Water flow meter.  We interrupt that signal with a simple contact closure so the system sees no water flow and will not start up.  Once it is "enabled" we close that contact via IP addressable relay, and the system sees the water flowing again.  (we never interrupt the water in reality, just the signal to the controller)  This has been working quite well for us, hope this helps.

Hi Mark. If not the computer, how about just the monitor? Or instead of the plasma gas line, how about the vent valve?

Subject: Implementing Lock-out/Logins on AJA Phase II J sputter system


Hello all,

We have an AJA Phase II J sputter tool that we need to implement our "Login" system on.

The system allows for  a open /closed circuit at 24v or 115v.

Most all of the sputter system is 230v. I do not want to have to power up the computer each time for someone to login and be able to use the tool.

At this point I believe that my best option is to have an electronic valve in the main plasma gas line as all gasses are routed through a single line.

I am looking for suggestions if anyone has a similar system in place on an AJA.

Thank you,



Mark Hofheins
