MDM Trouble Report for 2024 Aug 05 Telescope: 2.4m Observer(s): Galayda (MDM Observatory) Instrument: telescope Problem(s) Encountered: Set up the telescope for some engineering work and found that the brakes would not release. Further investigation found that pneumatic systems--brakes & mirror covers-- were nonfunctional through TCS GUI control. Testing mirror cover actuation using the physical switch on the MDC worked correctly. It appears that the J2 5-pin socket on the MDC power supply board had loosened just enough to break contact. Reseating this connector corrected the issue. ------------------------------ Submitted on 2024 Aug 7 [11:49:18]
