1BMSDirect NIP (unit 1)12/21/201307:00:0012/21/201316:22:00Due to a scheduled NREL power outage, to upgrade campus electrical infrastructure, The following BMS instruments were not pointing at the sun during this time: Direct NIP #1, LI-201, LI-190, NIP RG780, TWC; and the following instruments were un-shaded: Diffuse CM22, CUV4, CG4. The Middle Sci-Tec tracker for these instruments were temporarily put on a secondary UPS which failed immediately.
2BMSDirect NIP (unit 1)03/02/201313:06:0003/02/201318:24:00Due 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)
3BMSDirect NIP (unit 1)05/26/201206:15:0005/26/201207:12:00Due 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.
4BMSDirect NIP (unit 1)09/08/201108:23:0009/08/201109:38:00Due 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.
5BMSDirect NIP (unit 1)05/07/201105:55:0005/09/201107:58:00There 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
6BMSDirect NIP (unit 1)04/15/201106:43:0004/15/201106:50:00There was a planned power outage for SRRL construction activities that started at 6:11 MST. 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.

15BMS31137E6Direct NIP (unit 1)11/05/200506:37:0011/07/200508:10:00Sun 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.
16BMS31137E6Direct NIP (unit 1)07/23/200510:16:0007/24/200509:01:00Sun 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.
17BMS31137E6Direct NIP (unit 1)07/16/200500:00:0007/18/200507:46:00The 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.
18BMS31137E6Direct NIP (unit 1)06/06/200515:00:0006/07/200511:45:00A BORCAL instrument was mistakenly connected in parrallel with the NIP. Direct irradiance profile was distorted during this time.
19BMSDirect NIP (unit 1)06/19/200213:00:0006/26/200211:03:00A Global Pyranometer (to be calibrated in a BORCAL) was mistakenly connected in parallel with the NIP during this time period. This caused the NIP to read too low during sunny conditions and too high during very cloudy conditions.
20BMSDirect NIP (unit 1)08/01/200000:00:0010/31/200023:59:00SRRL BMS was undergoing upgrade and reinstallation on the new instrument deck during this time. To keep a continuos data set for BMS, Direct NIP data from SRRL BSRN was used. Note: The BSRN Direct and Diffuse Trackers failed on Aug 5, 6, 17, 18. BMS Diffuse and Direct data on those 4 days were set to missing values (-99999).
