MY Temperatur Drop Alarm: Related to Fan Work On Tues (7/18/2023)

Received another Low MAJOR (red) Alarm Handler alarm similar to what RyanC reported overnight.  Attached are relevant trends.  The chiller looks operational; MY VEA temperature sensors took a step down on Tues morning (correlating with Tues Maintenace Fan lubricating), and the MY VEA is now a full 10degF lower since Tuesday's fan work.  Although it's only a mid-station, I will still send a text to Bubba (I reckon due to the drop is equalizing below the LOW alarm setting, this alarm will be ongoing until temperatures raise or the alarm settings are changed).
