1BMSGlobal Normal12/30/202112:33:0012/30/202116:39:00The 2-axis tracker failed under high wind conditions and is facing in a north east position, data from the following instruments should not be used until repaired:: Global Normal CMP22, SP-Lite2, LI-200R, WISER. Tracker was power cycled after the wind died down to force it resume normal tracking operations.
2BMSGlobal Normal12/15/202108:00:0012/16/202108:25:00The 2-axis tracker failed under high wind conditions and is facing in a north east position, data from the following instruments should not be used until repaired:: Global Normal CMP22, SP-Lite2, LI-200R, WISER. Tracker was power cycled the following day (with sun sensor disconnected) to force it resume normal tracking operations. Sun sensor is now connected and it seems to be working.
3BMSGlobal Normal09/17/202115:13:0009/23/202107:55:00For an experiment, the 1-axis and 2-axis trackers were placed in a 40-degree South Fixed Tilt, this affects the following instruments: Global Normal CMP22, SP-Lite2, LI-200R, WISER; Global 1-Axis CMP22, SP-Lite2, LI-200R, WISER

8BMSGlobal Normal07/28/201800:00:0007/30/201809:30:00The global normal tracker was not working during this time, data for the Global Normal CMP11 and LI-200R should not be used. Problem Unknown.
9BMSGlobal Normal07/22/201800:00:0007/23/201808:45:00The 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. Power cable had come unplugged to AC adapter. AC adapter was relocated to prevent future unplugging.
10BMSGlobal Normal02/21/201700:00:0002/22/201709:15:00The 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.
11BMSGlobal Normal02/17/201700:00:0002/17/201713:00:00The 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.

24BMSGlobal 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.
25BMSGlobal 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.
