26	BMS		Photometer TWC	07/12/2011	22:57:00	07/13/2011	07:40:00	Due to a tripped GFCI outlet at SRRL the following instruments were without power during this time: TWC & POM-01 Photometers, Direct CUVA2 & CUVB2, and the PGS100. The readings are either zero or bogus and should not be used. GFCI was tripped due to Eppley venitlators which were water logged by thunderstorm.

30	BMS		Photometer TWC	05/07/2011	05:55:00	05/09/2011	07:58:00	There was a planned power outage for SRRL construction activities that started at 5:18 MST. Unfortunately, the backup generator provided to SRRL was providing bad power to the UPS powering the Sci-Tec trackers, therefore the UPS failed at 5:55 MST. Unfortunately, when normal AC power was restored at 11:45 MST, the Sci-Tec trackers had lost all their configuration due to UPS cycling on and off during the outage, therefore were not tracking. The tracker settings were restored on May 9 at 7:58 MST. The following BMS instruments were not pointing at the sun during this time: Direct CH1, NIP #2, NIP #1, LI-201, NIP RG780, CUVA2, CUVB2, TWC; and the following instruments were un-shaded: Diffuse 8-48, PSP, CM22, CUV4, PIR, CG4

32	BMS		Photometer TWC	04/15/2011	06:11:00	04/15/2011	06:50:00	Due to a planned power outage for SRRL construction activities, the following BMS instruments were down: TSP-1, TSP-700, UVSAT, UVSBT, CUVA1, CUVA2, CUVB1, CUVB2, UVB-1, 501A, MS210W, SPN1, TSI-880, PGS-100, POM-01, TWC, EFM-100.
33	BMS		Photometer TWC	03/18/2011	00:00:00	03/18/2011	07:57:00	The Sci-Tec #2 tracker was jammed on the shading plate. The following instruments were unshaded: CM22, CUV4, CG4; and the following instruments were not pointing at the sun: NIP #1, NIP RG780, LI-201, TWC Photometer.
34	BMS	0001	Photometer TWC	10/30/2010	00:00:00	11/01/2010	11:27:00	The Sci-Tec #2 tracker was apparently not working during this time. The following instruments were unshaded: CM22, CUV4, CG4; and the following instruments were not pointing at the sun: NIP #1, NIP RG780, LI-201, TWC.
35	BMS		Photometer TWC	12/09/2009	12:11:00	12/09/2009	14:22:00	Due to a power outage at NREL, followed by bad power, the SRRL tracker UPS shutdown. The following BMS instruments were not pointing at the sun: Direct CH1, NIP1, NIP2, NIP-RG780, LI201, TWC500, CUV4; and the following instruments were unshaded: 8-48, CM22, PSP, CUV4, PIR, CG4.

37	BMS		Photometer TWC	11/15/2008	14:02:00	11/15/2008	14:32:00	Due to a planned power outage at SRRL, the following BMS instruments were not pointing at the sun: Direct CH1, NIP1, NIP2, LI201, TWC500, CUV4.
38	BMS	0001	Photometer TWC	09/30/2008	14:18:00	10/01/2008	15:00:00	The TWC photometer was not properly aligned with the sun after being relocated to the Sci-Tec tracker. Shims were added on 10/1/08 to improve alignment.
39	BMS		Photometer TWC	12/22/2007	08:41:00	12/22/2007	11:24:00	Due to a scheduled SRRL/Mesa Top power outage on 12/22/2007, the TSP-1, TSP-700, All Global UVA and UVB, and the TWC Photometer were without power, therefore data is either bad or bogus.
40	BMS	0001	Photometer TWC	05/25/2006	10:50:00	05/25/2006	11:26:00	Sun Follower III tracker was down due to power shutdown for installation of new SRRL equipment lift. The following instruments were NOT pointing at the SUN: NIP #1, NIP RG780, CUVB2, LI-201, TWC (500nm).
41	BMS		Photometer TWC	01/08/2004	00:00:00	12/21/2005	14:53:00	TWC Photometer was down due to detector failure. Detector and filter was replaced and the unit was returned to service. A new Vo calibration constant will need to be generated on the next clear day.
42	BMS		Photometer TWC	12/13/2000	07:21:00	12/15/2000	09:46:00	The 500nm Photometer was disconnected for repair. The instrument had been giving noisy signal at night between midnight and sunrise, and high voltage output (up to 13.5 V) at approx. 7:30 MST (almost every day), which caused the datalogger to put out missing values (-99999) due to over-ranging. This was caused by broken or loose connections in the instrument cable and depending on the position of the tracker the wires supplying power to the instrument shorted with the wires carrying the signal from the instrument. This wire has been repaired are re-oriented to help prevent future damage.
43	BMS		Photometer TWC	11/01/2000		08/23/2001	12:00:00	An incorrect calibration factor of 0.487 W/mē/nm/mV was in the datalogger during this time period. The correct factor should have been 0.388 W/mē/nm/mV. This data was repaired on 6-14-2002, a correction is NOT required.
