MDM Trouble Report for 2023 Jun 24

Telescope: 1.3m
Observer(s): John Thorstensen (Dartmouth)
Instrument: Templeton direct

Problem(s) Encountered:
Everything worked, but when I went to fill the dewar in the
early morning hours I heard a high-pitched alarm sound coming
from the 1.3m generator.  I looked at the control panel (door
on NE side) and found the illuminated gauges blinking (and 
also a blinking red light, if I remember correctly).  

There is a three-position dial switch on the panel that 
says AUTO and OFF (and something else; run? test?). It was
on AUTO. I switched it to OFF and the alarm stopped immdiately.
I then turned it back to AUTO, and the alarm did not resume, so
I seem to have cleared the problem, at least for now.
