MDM Trouble Report for 2002 Nov 6

Telescope: 2.4m
Observer(s): Monique Aller (University of Michigan)
Instrument: Wilbur + MODSPEC

Problem(s) Encountered:
I had two (minor) problems during the night. First, I 
had the guider PC die twice. That is it completely refused
to respond to any commands on the keyboard. The first time
it would beep when I hit a key. The second time it
died, it did not even beep when I hit keys. (Also, shortly
before the second time it died I was shocked on the handpaddle,
which may or may not have caused the failure.) Both times I
was only able to fix the problem by turning off the PC and
restarting it. This seemed to fix the problem both times.
The other minor problem I had was when I went to one of
my sources. The telescope went to the position, and I could
see the object on the guide television. The telescope refused
to admit that it was there, however, and after a couple of
minutes of  Moving  appearing on the TCS screen, it printed
the message  Dec Encoders Not Responding . At this point I
hit the stop button on the xtcs window and then resent the
coordinates and hit go. This time, although there was another
lengthy delay of  Moving , even though the telescope was looking
at the source, it eventually seemed to accept that it was on
the source. This problem did not repeat itself during the night,
and was probably a minor glitch.
