1BMSDirect NIP RG78012/21/201307:00:0012/21/201316:22:00Due 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 RG78003/08/201308:00:0003/11/201307:55:00The RG780 filter was not covering the NIP during this time. Most likely left open during a cleaning event.
3BMSDirect NIP RG78003/02/201313:06:0003/02/201318:24:00Due 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)
4BMSDirect NIP RG78005/26/201206:15:0005/26/201207:12:00Due 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.
5BMS17837E6Direct NIP RG78010/14/201108:37:0010/17/201108:46:00The RG780 filter was not covering the NIP during this time. Most likely left open during a cleaning event.
6BMSDirect NIP RG78009/08/201108:23:0009/08/201109:38:00Due 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.
7BMSDirect NIP RG78005/07/201105:55:0005/09/201107:58:00There 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
8BMSDirect NIP RG78004/15/201106:43:0004/15/201106:50:00There 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.
9BMSDirect NIP RG78003/18/201100:00:0003/18/201107:57:00The 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.
10BMS31355E6Direct NIP RG78010/30/201000:00:0011/01/201011:27:00The 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.
11BMS17837E6Direct NIP RG78006/10/201006:20:0006/11/201007:40:00The RG780 filter was not covering the NIP during this time. Most likely left open during a cleaning event.
12BMSDirect NIP RG78012/15/200909:40:0012/15/200910:00:00The 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.
13BMS17837E6Direct NIP RG78007/30/200912:45:0007/30/200923:59:00The 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.
14BMS17837E6Direct NIP RG78005/25/200610:50:0005/25/200611:26:00Sun 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).
15BMS17837E6Direct NIP RG78011/17/200506:51:0011/17/200508:32:00The RG780 filter was not covering the NIP during this time. The Filter Wheel had moved sometime before sunrise to the half open position, most likely caused by a bird sitting on the wheel.
16BMS17837E6Direct NIP RG78011/05/200506:37:0011/07/200508:10:00Sun 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.
