1BMSDirect TUVR03/24/201600:00:0003/24/201610:10:00There was an alignment problem on one side of the sci-tec tracker from sunrise to 10:10 MST that caused the Direct TUVR to read low.
2BMSDirect TUVR12/24/201411:20:0012/27/201414:45:00On 24 Dec, contractors bumped into the side of the Sci-Tec tracker mount which sent the Direct CH1, Direct TUVR, and Direct CUVB2 slightly out of alignment. Data is low and saw tooth shaped during this time due to misalignment.
3BMSDirect TUVR12/23/201411:50:0012/23/201413:20:00Solder joint at outdoor bendix connector broke. Data is bogus during this time.
4BMSDirect TUVR12/28/201311:55:0012/28/201315:59:00Due 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 CH1, NIP #2, CUVA2, CUVB2, TUVR; and the following instruments were un-shaded: Diffuse 8-48, PSP, PIR. The South Sci-Tec tracker for these instruments are protected by UPS, however the battery depleted at 11:55 MST (the power outage started at 6:46 MST)
5BMSDirect TUVR12/21/201310:30:0012/21/201316:22:00Due 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 CH1, NIP #2, CUVA2, CUVB2, TUVR; and the following instruments were un-shaded: Diffuse 8-48, PSP, PIR. The South Sci-Tec tracker for these instruments are protected by UPS, however the battery depleted at 10:30 MST (the power outage started at 7:00 MST)
6BMSDirect TUVR03/15/200400:00:0012/31/200523:59:00The Direct TUVR is experiencing intermittent signal problems, some days its good others its bad. Instrument was permanently removed from service sometime after 6/30/06, however data after 12/31/05 is not available (or should be ignored).
7BMSDirect TUVR12/27/200300:00:0003/10/200410:11:00The Direct TUVR is experiencing intermitten signal problems, some days its good others its bad. On 3-10-2004, the TUVR sensor was shorted from 9:42 to 10:10 MST in an effort to reset the detector.
8BMSDirect TUVR08/12/200305:00:0009/26/200318:00:00The Direct TUVR is experiencing intermitten signal problems, some days its good others its bad.
9BMSDirect TUVR03/13/200200:00:0006/07/200208:08:00The Direct UV is experiencing intermitten signal problems, some days its good others its bad. The instrument was factory serviced and the problem has been corrected.
10BMSDirect TUVR12/02/200110:00:0002/19/200215:01:00The Direct UV is experiencing intermitten signal problems, some days its good others its bad. On 2-19-2002, the TUVR sensor was shorted from 13:00 to 15:00 in an effort to reset the detector. This seemed to solve the problem.
11BMSDirect TUVR06/27/200109:46:0008/08/200110:10:00The direct normal UV was removed from service due to moisture leak. A new fused silica glass window and mount has been fitted by the machine shop to avoid future moisture leaks.
12BMSDirect TUVR05/29/200114:01:0006/22/200115:30:00The direct normal UV was removed from service due to moisture leak.
13BMSDirect TUVR12/13/200013:18:0012/14/200015:00:00The direct normal UV was down due to broken signal cable.
14BMSDirect TUVR11/01/200000:00:0011/06/200013:03:00The direct normal UV is disconnected, instrument is awaiting special mount for Sci-Tec tracker.
15BMSDirect TUVR07/07/200011:00:0007/10/200007:45:00The direct normal UV radiometer was down due to tracker failure.
16BMSDirect TUVR06/21/200009:30:0006/23/200013:24:00The direct normal UV radiometer was down due to tracker failure.
17BMSDirect TUVR06/01/200008:30:0006/01/200010:50:00The direct normal UV radiometer was down due to tracker failure.
18BMSDirect TUVR04/23/200004/24/200008:17:00The direct normal UV radiometer was down due to tracker failure.
19BMSDirect TUVR04/11/200004/12/200008:46:00The direct normal UV radiometer was down due to tracker failure caused by a power failure that occurred on April 11.
20BMSDirect TUVR10/06/199914:00:0010/10/199913:40:00The direct normal UV radiometer was removed from the solar tracker and the signal shorted during the cavity comparisons.
21BMSDirect TUVR03/03/199903/31/199914:44:00The Direct Normal Total Ultraviolet Radiometer (TUVR) s/n 18115 had an intermittent signal problem and was removed for service during this time period. The instrument was sent to The Eppley Laboratory, Inc. for repair and calibration.
22BMSDirect TUVR09/04/199813:30:0009/17/199809:20:00Direct Normal Ultraviolet radiometer was disabled after solar tracker failure. We installed a signal shorting plug (output fixed at 0.00 VDC).
