1BMSDownwelling CG412/21/201307:00:0012/21/201316:22:00Due 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.
2BMSDownwelling CG403/02/201313:06:0003/02/201318:24:00Due 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)
3BMSDownwelling CG405/26/201206:15:0005/26/201207:12:00Due 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.
4BMSDownwelling CG409/08/201108:23:0009/08/201109:38:00Due 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.
5BMSDownwelling CG405/07/201105:55:0005/09/201107:58:00There 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

16BMS010548Downwelling CG405/25/200610:50:0005/25/200611:10:00Sci-Tec tracker #2 tracker was down due to power shutdown for installation of new SRRL equipment lift. The following instruments were UNSHADED: Diffuse CM22, Diffuse UVB-1 and the CG4.
17BMS010548Downwelling CG401/11/200614:17:0001/31/200623:59:00The CG4 was using miscalculated K-factors, during this time frame the downwelling irradiance could be off by about +/-10 W/m2. The incorrect factors were: K0=-3.37; K1=0.081; K2=1.01. The correct factors should have been: K0=-3.37; K1=0.0765; K2=1.008.
18BMS010548Downwelling CG411/05/200506:37:0011/07/200509:19:00Sci-Tec Tracker #2 was down due to a power outage on 11/4/2005 at 23:14 MST. Tracker failed to automatically reposition when power was restored on 11/5/2005 at 5:02 MST, due to failed internal battery. The following instruments were UNSHADED: Diffuse CM22, Diffuse UVB-1 and the CG4. The AOCS was not pointing at the SUN.
19BMS010548Downwelling CG407/23/200510:16:0007/25/200507:07:00Sci-Tec Tracker #2 rotated the wrong direction and hung up on the signal cables, due to a scheduled NREL power outage on 7/23/2005 at 5:33 MST. The following instruments were UNSHADED: Diffuse CM22, Diffuse UVB-1 and the CG4.
20BMS010548Downwelling CG407/10/200505:56:0007/11/200508:00:00Sci-Tec Tracker #2 rotated the wrong direction and hung up on the signal cables, due to a momenatary power loss. The following instruments were UNSHADED: Diffuse CM22, Diffuse UVB-1 and the CG4.
21BMSDownwelling CG401/07/200211:25:0003/14/200209:21:00Due to a shortage of diffuse trackers the CG4 had to be removed from service temporarily, to allow for another instrument to be calibrated under the shading ball. The Net Infrared, Downwelling Infrared, and Case Temperature for the CG4 have been forced to read zero to indicate that it's out of service.
