1BMSGlobal 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.

7BMSGlobal Normal05/08/201308:29:0005/09/201312:59:00The global normal signal cable was being replaced during this time. Data is bogus.
8BMSGlobal Normal05/06/201318:30:0005/06/201321:30:00The global normal signal cable is breaking and reporting bogus data during this time.
9BMS910056Global 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.
10BMS910002Global 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.

13BMSGlobal 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.
