MDM Trouble Report for 2011 Dec 14 Telescope: 2.4m Observer(s): Murphy, Santana (Ohio University) Instrument: R4K Problem(s) Encountered: When power cycled off the generator and back onto the electrical grid, there was an apparent failure of the airbag controller and/or the airbags themselves. The three telescope hard point values make no sense whatsoever, (very far from the 30 value we want) and there are a series of error messages on the monitor: dgh error 1 in read_dgh_response '?1 NOT READY' ... plus many more errors of a similar nature. We also stopped hearing the usual sequence of clicking sounds from the airbags at that point. ------------------------------ Submitted on 2011 Dec 15 [2:05:16]
