3 | BMS | | Direct LI-190 | 11/22/2022 | 00:00:00 | 11/23/2022 | 23:59:00 | Due 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. |
4 | BMS | | Direct LI-190 | 08/22/2022 | 00:00:00 | 08/25/2022 | 08:03:00 | Due 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. |
5 | BMS | | Direct LI-190 | 08/21/2022 | 00:00:00 | 08/21/2022 | 23:59:00 | Due 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). |
6 | BMS | | Direct LI-190 | 03/09/2019 | 08:40:00 | 03/09/2019 | 13:01:00 | Due 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. |
7 | BMS | | Direct LI-190 | 01/17/2017 | 07:15:00 | 01/17/2017 | 08:56:00 | Due 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. |
8 | BMS | | Direct LI-190 | 05/02/2015 | 09:00:00 | 05/02/2015 | 18:53:00 | Due 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. |
9 | BMS | | Direct LI-190 | 12/21/2013 | 07:00:00 | 12/21/2013 | 16:22:00 | Due 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. |
10 | BMS | | Direct LI-190 | 12/05/2013 | 09:00:00 | 12/16/2013 | 09:30:00 | The 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. |
11 | BMS | | Direct LI-190 | 03/02/2013 | 08:06:00 | 03/02/2013 | 18:24:00 | Due 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. |
