Thanks Tyler, Pablo for coming in the hall and did the best you can do.</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
The controlled power on Solenoid is in place and will be in place till we complete the solenoid checks first.</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Once we are satisfied and completed, we shall move the controller power to the torus MPS (Krister will do that when we complete the work on Solenoid).</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
The MPS (both) are locked and tagged by Krister. He will be available to do that independent of us.<br>
I will let you know once we are ready to start checks. You can remotely clear the interlocks before you start from home just to check.</div>
