1BMSDirect LI-19009/29/202312:40:0009/29/202313:55:00Due to an NREL-wide power outage caused by Xcel Energy, The following BMS instruments were not pointing at the sun during this time: Direct CHP-2, NIP, DR02, RG780, TWC, LI-201, LI-190; and the following instruments were un-shaded: Diffuse SR25, CM22-1, CG4.
2BMSDirect LI-19012/01/202212:08:0012/01/202213:01:00Due to BMS middle sci-tec backup battery replacement (which requires soldering), The following BMS instruments were not pointing at the sun during this time: Direct CHP-2, NIP, DR02, RG780, TWC, LI-201, LI-190; and the following instruments were un-shaded: Diffuse SR25, CM22-1, CG4. However automatic substitution was enabled for the CHP1-2, SR25, and CM22-1.
3BMSDirect LI-19011/22/202200:00:0011/23/202223:59:00Due to BMS middle sci-tec failure, The following BMS instruments were not exactly pointing at the sun during this time: Direct CHP-2, NIP, DR02, RG780, TWC, LI-201, LI-190; and the following instruments were just barely shaded: Diffuse SR25, CM22-1, CG4. On 11/23/2022, 11/22/2022 data for CHP1-2, NIP, SR25, and CM22-1 were replaced with primary measurements from south tracker. Note that data on 11/23/2022 were automatically substituded at the logger during middle tracker replacement.
4BMSDirect LI-19008/22/202200:00:0008/25/202208:03:00Due to BMS middle sci-tec failure, The following BMS instruments were not pointing at the sun during this time: Direct CHP-2, NIP, DR02, RG780, TWC, LI-201, LI-190; and the following instruments were un-shaded: Diffuse SR25, CM22-1, CG4. However automatic substitution was enabled for the CHP1-2, NIP, SR25, and CM22-1.
5BMSDirect LI-19008/21/202200:00:0008/21/202223:59:00Due to BMS middle sci-tec failure, The following BMS instruments were not pointing at the sun during this time: Direct CHP-2, NIP, DR02, RG780, TWC, LI-201, LI-190; and the following instruments were un-shaded: Diffuse SR25, CM22-1, CG4. On 9/14/2022 data for CHP1-2, NIP, SR25, and CM22-1 were replaced with primary measurements from south tracker (which were also reconstucted).
6BMSDirect LI-19003/09/201908:40:0003/09/201913:01:00Due to a scheduled NREL/SRRL power outage, to install power meters on the SRRL building, The following BMS instruments were not pointing at the sun during this time: Direct NIP, LI-201, LI-190, NIP RG780, TWC, DR02; and the following instruments were un-shaded: CG4.
7BMSDirect LI-19001/17/201707:15:0001/17/201708:56:00Due to a tripped GFCI powering the Sci-Tec tracker, The following BMS instruments were not pointing at the sun during this time: Direct CHP1 #2, NIP, DR02, LI-201, LI-190, NIP RG780, TWC; and the following instruments were un-shaded: Diffuse CM22 #1, CMP11, CG4.
8BMSDirect LI-19005/02/201509:00:0005/02/201518:53:00Due to a snagged signal cable on the Sci-Tec tracker, 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, CMP11, CG4.
9BMSDirect LI-19012/21/201307:00:0012/21/201316:22:00Due 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.
10BMSDirect LI-19012/05/201309:00:0012/16/201309:30:00The Direct LI-190 quantum sensor had been relocated to a new tracker. It was later discovered that between approx 9:10 and 9:40 MST of every day that the ventilator mounted on a different tracker (to the south) is shading the Direct quantum sensor for this brief period of time. Instrument will be relocated on a cloudy day. Instrument was swapped with the LI-201 on Dec 16. The LI-201 will be relocated later.
11BMSDirect LI-19003/02/201308:06:0003/02/201318:24:00Due 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 LI-190. This instrument was NOT mounted on a BMS Sci-Tec tracker at the time, so it was NOT protected by UPS.
