<p style="margin-top:0; margin-bottom:0">Hello,</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">The Torus had a second fast dump maybe an hour ago due to similar LCW issues.</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">There was also a controlled ramp down of the Solenoid at the same time due to a high PT8620. I'm having trouble going online via remote desktop from dsgcontrols1 (seems to be an RSLinx problem, in process of debugging)
so I haven't been able to verify that PT8620 going over its high interlock limit caused the controlled ramp down yet.</p>

<p style="margin-top:0; margin-bottom:0">Best regards,</p>

<p>Aside from both magnets doing a fast dump (which is new) from the data it looks like the manifold fix in November actually worked as there was a peak (~3:30) that previously would have caused the solenoid to dump and the second (~4:00) was what finally caused
the dump but since it was much more severe (loss of pressure) it took down both magnets.</p>
