11	SRRL 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.

20	SRRL 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.
21	SRRL 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).
22	SRRL 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.
23	SRRL 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.
24	SRRL 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.
