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)
8	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.
9	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.
10	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.

21	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.
22	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.
23	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).
