MDM Trouble Report for 2010 Jan 29

Telescope: 2.4m
Observer(s): Julie Skinner (Dartmouth College)
Instrument: echelle

Problem(s) Encountered:
I opened for a little under an hour after the humidity dropped below the limit.
However, shortly after opening the mirror airbag computer registered that the
airbags not working properly.  Bob and I tried to troubleshoot over the phone,
but were not able to solve the problem.  No breakers were flipped, we never lost 
power as far as I know, no lights on the box on the mirror cell.

Error messages on airbag computer:
Sensor unit x did not respond. - Shut down system!
serialio error 1 in read_dgh_echo '$1'
dgh error 6 in send_dgh_command 1,2
dgh error 6 in write_enable_dgh_unit unit 1,2
dgh error 6 in reset_dgh_unit unit 1,2
...and 73 more errors...
