We are unable to swap the RICH cRIOs to utility power as planned, so the RICH cRIOs will lose power during the outage and interlock sensor monitoring will<strong></strong> be lost.<br></div><div><strong><br></strong></div><div><em><strong>However, RICH's N2 supply is NOT dependent on power and N2 flow will remain continuous during the power outage.</strong></em><br></div><div><strong><br></strong></div><div>When clean power is restored and ODH monitoring is re-enabled, we will be able to access the Hall and confirm all cRIOs and sensors are functioning correctly.<br></div><br><div>Best regards,<br></div><div>Tyler</div></div><br></div></div><br>_______________________________________________<br>Dsg-rich mailing list<br>Dsg-rich@jlab.org<br>https://mailman.jlab.org/mailman/listinfo/dsg-rich<br></div></div></body></html>
