UPDATE - BNC Preventative Maintenance Closure & Research Equipment Power Outage
by Voorhis, Mark L. 15 Oct '19

15 Oct '19

Dear BNC User, Issues outside of our control switchboard #1 that supplies power to all the research equipment at the center was not fixed due to a safety interlock failure. This issue has to be fixed in order to safety power down switchboard #1 and fix the original bus duct issues. Purdue Campus high voltage crew and electrical shops are currently trying to figure out how to fix the safety issue to complete repairs to the original bus duct. The inspect and repairs on the other switchboard #2 showed lose grounding connections and several of the main bolts required tighten back to original torque settings. Based on this information we feel that switchboard #1 needs to be shut down again to complete repairs. Our hope is to finish switchboard #1 this week if possible but we am waiting on feedback from the Purdue high voltage crew and electrical shops to see if this is possible. If not then another shutdown for Switchboard #1 requiring to power off all research equipment will be needed. Please note that the building will remain closed till the end of the week to complete our normal preventive maintenance activates. We are sorry for the inconvenience but this issue is outside of our control. I will sent a updated once more information is available. Thank you, Mark Voorhis Building Manager Purdue University Birck Nanotechnology Center Office: (765) 494-3036 [Purdue_University-150_Years_of_Giant_Leaps] www.purdue.edu/giantleaps

NOTICE - BNC EMERGENCY SHUTDOWN OF CLEANROOM OPERATIONS
by Voorhis, Mark L. 12 Oct '19

12 Oct '19

Dear BNC Users, We have been dealing with the serious building controls issue since 10PM yesterday evening with the cleanroom heating system that could shut down our cleanroom research and operation. After detailed investigation and troubleshooting we need to order some unique control valve repair parts that we have not needed since we have open the center 14+ years. We are using contingency plans for our pre heating system to keep the cleanroom operational - but we are on the edge - when outdoor ambient temperatures reach freezing levels where uncontrollable safety sensors can shut down all makeup air systems that is critical to cleanroom operations causing the cleanroom to go super negative. For this reason we plan to shut down research and process in the cleanroom tonight at 12 midnight. Please make appropriate plans to secure your research that is sensitive to airborne contamination. All bulk gases and nitrogen to dry boxes in the center will remain operational with no interruption from now throughout next week. We are sorry for this unscheduled interruption and thank you for your cooperation. Best Regards, Mark Voorhis Building Manager Purdue University Birck Nanotechnology Center Office: (765) 494-3036 [Purdue_University-150_Years_of_Giant_Leaps] www.purdue.edu/giantleaps
