Hi Valery,</div>
<div dir="ltr" style="font-family: Aptos, Aptos_MSFontService, -apple-system, Roboto, Arial, Helvetica, sans-serif; font-size: 12pt;">

<div dir="ltr" style="font-family: Aptos, Aptos_MSFontService, -apple-system, Roboto, Arial, Helvetica, sans-serif; font-size: 12pt;">
When you get a chance can you please double check the temperature interlock limits for RICH S1?</div>
<div dir="ltr" style="font-family: Aptos, Aptos_MSFontService, -apple-system, Roboto, Arial, Helvetica, sans-serif; font-size: 12pt;">

<div dir="ltr" style="font-family: Aptos, Aptos_MSFontService, -apple-system, Roboto, Arial, Helvetica, sans-serif; font-size: 12pt;">
During today’s work, the interlock limits got overwritten to all zeros. </div>
<div dir="ltr" style="font-family: Aptos, Aptos_MSFontService, -apple-system, Roboto, Arial, Helvetica, sans-serif; font-size: 12pt;">
Marco M. found a screenshot of what the limits used to be so that’s what we used, but it seems like they’ve changed since that screenshot (hence his recent logbook entry about increasing the limit from 35 C to 39 C). </div>
<div dir="ltr" style="font-family: Aptos, Aptos_MSFontService, -apple-system, Roboto, Arial, Helvetica, sans-serif; font-size: 12pt;">

<div dir="ltr" style="font-family: Aptos, Aptos_MSFontService, -apple-system, Roboto, Arial, Helvetica, sans-serif; font-size: 12pt;">
Thanks, </div>
