DIN	Date	Beamline	Status	Duration	Group	Description	Resolution
475	11/09/04	16-ID	Open	2 hr 53 min	ASD-SI	BLP unable to search/secure D-station. Pneumatic Door # 2 open/close LEDs both off and door close button will not activate door closure.	16-ID-D Pneumatic Door # 2 switches required repair. Beamline Operations restored following APS Management approval.
478	11/12/04	24-ID	Open	18 min	ASD-VAC	BP requested opening the BIV on mezzanine. Confirmed that vacuum pressures were OK and opened BIV valve at 17:34.
479	11/10/04	09-ID	Open	46 min	ASD-VAC	BP reported a Serious fault at 1700. BP was trying to open the shutter when fault occurred. Suspected Serious fault #160 (P9CMS1_NOSWITCH) but due to APS network being DOWN (15:57-17:13) - could not confirm what fault occurred. Called Roy Emerson -PSS came to beamline. After network restored - we checked EPICS and saw Serious fault #160 (P9CMS1_NOSWITCH) - Roy reset the fault. Shutter was cycled a number of times without a problem (after fault reset). Fault cleared & shutter opened at 17:46 pm. Roy recommended VACUUM group check out shutter. Trey Leng inspected and will replace seals during Machine Intervention. Submitted Work Request 16308.
