<p>Dear network members,<br>
</p>
<p><br>
</p>
<p>We have two turbo pump controllers (Mag Drive 1000, to drive MAG 900 turbo pump) out of order. It shows "Bearing Sensor" "Levitation Fail" onto the display. We swarp a good controller to the system, no error message appear. I guest the fault is come form
the controller itself. However, I contact with Leybold but they said this model is obsoleted, no service can be provide further. <br>
</p>
<p><br>
</p>
<p>Is there any suggestion of company can provide service to repair the controllers? <br>
