Hello Julia,<br>
<br>
We had our pump go out in 2014 and decided to replace it with a
different manufacturer's pump and controller. Our STS DRIE is a
legacy tool with limited support, so we decided to start upgrades
ourselves.<br>
<br>
We went with a Edwards STPA1303CV pump and SCU800 controller with
associated cables and vent valve. The total price was a lot less
than the STS OEM solution and we were able to get it in days rather
than months. This pump is a 1300L/s rather than the older 900L/s,
but we see no difference in processes, the throttle valve takes care
of that. We did have to create a custom interface for the
controller to the STS DRIE, but this was because we did not want to
cut the cable and just use a plug in replacement. We used something
like this part below for the interface:<br>
<br>

<br>
The DRIE computer is sending a signal to start the pump and looking
for feedback that the pump is at 100% speed. Our engineer got all
this installed and we have been running for the past 4 years without
any pump issues. We may still have the old MAG DRIVE 1000
controller on a shelf, I'll take a look later. The good news is
there is a path forward.<br>
<br>
Best Regards,<br>
Brent<br>

<p class="MsoNormal">Hi Julia,<o:p></o:p></p>

<p class="MsoNormal">Sorry to hear about your Leybold Mag Drive
turbo controller. I have been dreading the day our (last) Mag
drive 1000 dies. I acquired one as backup a few years ago but
the drive in use died and was not able to be repaired. So we
are down to our last one and its currently in use.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have spent some time looking at the
control signals and the good news is that I think you can
interface a different pump controller. We were under the
impression for a long time that the interface was something
special and required a $100k STS retrofit (that included the
new turbo and controller). I’ve gotten as far as
understanding the Leybold interface and making some notes on
how I think it operates. I have been planning on figuring out
how to install a replacement controller that can utilize the
existing STS interface signals but I haven’t started that.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If you get to the place where you just have
to put on a different turbo, I would be happy to share what
I’ve generated.<o:p></o:p></p>

The controller (MAG.DRIVE 1000) for the turbo pump wont
