1	SRRL BMS		Direct LI-201	03/02/2013	13:06:00	03/02/2013	18:24:00	Due to a scheduled NREL power outage, to upgrade campus power capacity, 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. The Sci-Tec tracker for these insruments are protected by UPS, however the battery depleted at 13:06 MST (the power outage started at 8:06 MST)
2	SRRL BMS		Direct LI-201	05/26/2012	06:15:00	05/26/2012	07:12:00	Due to a planned power outage for SRRL electrical work, the following BMS instruments were not following the sun: NIP #1, RG780 NIP, LI-201, TWC Photometer and the following instruments were not shaded CM22, CUV4, and CG4.
3	SRRL BMS		Direct LI-201	09/08/2011	08:23:00	09/08/2011	09:38:00	Due to a planned power outage for SRRL construction activities, the following BMS instruments were not following the sun: NIP #1, RG780 NIP, LI-201, TWC Photometer and the following instruments were not shaded CM22, CUV4, and CG4.
4	SRRL BMS		Direct LI-201	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

Unfortunately, the UPS powering the Sci-Tec trackers failed due to bad/old batteries at 6:43 MST. The following BMS instruments were not point at the sun for this brief period of time: CH1, NIP #2, NIP #1, LI-201, NIP RG780.
6	SRRL BMS		Direct LI-201	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.
7	SRRL BMS	PYHR100	Direct LI-201	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.
8	SRRL BMS		Direct LI-201	12/15/2009	09:40:00	12/15/2009	10:00:00	The Sci-Tec #2 tracker collided with another empty Sci-Tec tracker. The following instruments were unshaded: CM22, CUV4, CG4; and the following instruments were not pointing at the sun: NIP #1, NIP RG780, LI-201.
9	SRRL BMS		Direct LI-201	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.
10	SRRL BMS	PYHR100	Direct LI-201	07/30/2009	12:45:00	07/30/2009	23:59:00	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.
11	SRRL BMS		Direct LI-201	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.
12	SRRL BMS	PYHR100	Direct LI-201	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).
13	SRRL BMS	PYHR100	Direct LI-201	05/08/2006	08:30:00	05/08/2006	15:30:00	The LICOR sensor was signal was erratic and very large (up to 6000 W/m^2). Cause is unknown, however there may have been patching for BORCAL 2006-01 occuring on that day.
14	SRRL BMS	PYHR100	Direct LI-201	11/05/2005	06:37:00	11/07/2005	08:10:00	Sun Follower III tracker was down due to a power outage on 11/4/2005 at 23:14 MST. The following instruments were NOT pointing at the SUN: NIP #1, NIP RG780, CUVB2, LI-201.
15	SRRL BMS	PYHR100	Direct LI-201	07/23/2005	10:16:00	07/24/2005	09:01:00	Sun Follower III tracker was down due to a scheduled NREL power outage on 7/23/2005 at 5:33 MST. The following instruments were NOT pointing at the SUN: NIP #1, NIP RG780, CUVB2, LI-201.
16	SRRL BMS	PYHR100	Direct LI-201	07/16/2005	00:00:00	07/18/2005	07:46:00	The Sun Follower III tracker was hung up on cables, due to a research NIP removal that occured earlier in the week. This instrument was not pointing at the sun during this time.
17	SRRL BMS	PYHR100	Direct LI-201	01/01/2004	00:00:00	09/23/2008	14:00:00	The LI-201 has been having a moisture leak that has been gradually getting worse over time. Instrument was removed from service on 9/3/2008 @ 13:50 MST so that it could be disassembled and dried. Listed start date is approximate. Instrument was returned to service 9/23/2008 @ 14:00 MST, however instrument needs to be re-calibrated, since the annual calibrations on the unit were resulting in calibration factors that were artificially high (to compensate for moisture leak).
