MDM Trouble Report for 2025 Nov 24 Telescope: 2.4m Observer(s): Eric Galayda (MDM Observatory) Instrument: telescope Problem(s) Encountered: Weather station was hung. Simple power cycle appears to have resolved this issue. I think. Pneumatic leak was obvious in the dome, noted by the loud sound of blowing air. Traced it to the declination brake line. Found the failure at the caliper-end connector. Tony replaced this and all is well. The funnest one of the day: the 2.4m TCS PC was dead when I arrived this morning. Testing indicated likely to be a failed PSU. Got a similar (not exact) spare from the summit and it essentially works . There are issues however: 1) The resolution on one of the monitors is incorrect, leading to fuzzy and blown up graphics for the TCS GUI (left monitor only). 2) The graph display for MaximDL no longer appears--I suspect it is opening off the filed of view for the monitor. I believe at least item 1) may be related to the wrong PSU being used currently: it only provides connection for a 4-pin ATX12V processor connector instead of a 8-pin EPS12V connector. I have 2 spare PSUs being shipped (delivery expected tonight) and will install the correct PSU tomorrow. Hopefully this will resolve at least the resolution issue, if not resolve both issues. If the issue with the guide plot for MaximDL persists, I will contact the vendor and ask how to find the graph display (unless someone knows how to find a program's sub-window that is off the monitor's FOV?). Regardless, things should be good to go for tonight, which is the most important thing at the end of the day. One final issue: the flat lamp was not working when tested. Found a loose connection and rewired it. ------------------------------ Submitted on 2025 Nov 24 [16:10:46]
