1BMSGlobal Normal LI-200R02/21/201700:00:0002/22/201709:15:00The global normal tracker was not working during this time (pointed toward ground), data for the Global Normal CMP11 and LI-200R should not be used. Corroded connector was found at battery, replaced connector which restored 18 VDC to tracker.

5BMSGlobal Normal LI-200R02/04/201700:00:0002/06/201709:00:00The global normal tracker was not working during this time (pointed toward ground), data for the Global Normal CMP11 and LI-200R should not be used.
6BMSGlobal Normal02/04/201700:00:0002/06/201709:00:00The global normal tracker was not working during this time (pointed toward ground), data for the Global Normal CMP11 and LI-200R should not be used.
7BMSGlobal Normal LI-200R01/06/201700:00:0001/17/201713:50:00The global normal tracker has been having occasional tracking problems on various days during this time frame, data for the Global Normal CMP11 and LI-200R may be affected.
8BMSGlobal Normal01/06/201700:00:0001/17/201713:50:00The global normal tracker has been having occasional tracking problems on various days during this time frame, data for the Global Normal CMP11 and LI-200R may be affected.
9BMSGlobal Normal LI-200R12/01/201613:00:0012/05/201612:26:00When the LI-200R was first installed the data logger output was accidentally set to sample instead of average during this time, so data was 1-minute samples instead of 1-minute averages, as a result data will disagree with other instruments during cloud passage.
10BMSGlobal Normal LI-200R12/01/201613:00:0012/14/201608:44:00When the LI-200R was first installed the calibration factor at 45 degrees was used instead of the preferred 0 degrees for global normal:CF@45=91.575 W/mē/mV; CF@0=91.707 W/mē/mV.
11BMS140840Global Normal07/04/201600:00:0007/05/201614:00:00The LICOR LI-2020 tracker is not working during this time, data should not be used during this time.
12BMS140840Global Normal01/17/201600:00:0001/18/201615:30:00The LICOR LI-2020 tracker is not working during this time, data should not be used during this time.
13BMS140840Global Normal09/21/201500:00:0009/21/201514:20:00The LICOR LI-2020 tracker is not working during this time, instrument is facing northward/downward.
14BMS140840Global Normal08/12/201512:00:0008/28/201514:00:00The LICOR LI-2020 tracker for the Global Normal CMP11 has failed. Instrument is pointed in a somewhat southeasterly direction. Tracker was replaced on 8/28/2015.
15BMS920056Global Normal09/12/201400:00:0009/15/201409:15:00The CM21 was found on 9/12/2014 with moisture inside the inner and outer dome. Instrument was removed from service on 9/15/2014 at 08:53 MST and replaced with the calibration spare (it was due to be swapped out anyway).
16BMSGlobal Normal05/08/201308:29:0005/09/201312:59:00The global normal signal cable was being replaced during this time. Data is bogus.
17BMSGlobal Normal05/06/201318:30:0005/06/201321:30:00The global normal signal cable is breaking and reporting bogus data during this time.
18BMS910056Global Normal08/16/201100:00:0008/16/201112:10:00Solar tracker was not tracking the sun and was fixed in an easterly direction. Tracker was reset at approx. 12:10 MST.
19BMS910002Global Normal03/06/201110:43:0003/09/201112:11:00Signal is negative or bogus during this time. Bendix connector at instrument was re-seated which seemed to fix the problem.
20BMSGlobal Normal09/05/201000:00:0009/07/201009:11:00The LICOR tracker for the Global Normal CM-21 was not functioning during this time. Data is bad.
21BMSGlobal Normal12/16/200214:43:0012/17/200210:57:00The J-Box on the BMS Radiometer Tower was being replaced, data from this instrument is missing or bogus.
22BMSGlobal Normal11/01/200000:00:0011/07/2000The LI-COR LI-2020 Solar Tracker is powered by a PV panel with backup battery, however the charging cycle does not work correctly. Therefore the battery does not recharge after cloud cover and the tracker stops. The battery has to be (manually) swapped with another charged battery, until the problem is corrected.
