I think there is some documentation in the big white Master Electrical binder (upstairs in the cabinets). But if one of the circuit boards has gone bad, then the whole system might be DOA. </div> <div><br> </div> <div>The control boards are all under the layout on that distribution panel that feeds each block (not in the main dispatch panel; that just contains the flashing LED indicators).</div> <div><br> </div> <div>The only thing the small relay does is to flash the LED indicators. I can't remember if you pull the relay out if all the indicators just stay lit when a block is occupied (and not flash), or if they don't light at all. I'd have to look at that. </div> <div><br> </div> <div>I do remember that the entire block system is fed by the common rail. So if there's a break leading back to the detector boards, it might knock out the whole system. I'd have to look. But as I remember it was a confusing system because of how intertwined it is with existing track power. </div> <div><br> </div> <div>If no one else wants to tackle it, I could take a look. But it might be time to think about a replacement system. <br> <br> <div><span class="Apple-style-span" style="-webkit-tap-highlight-color: rgba(26, 26, 26, 0.296875); -webkit-composition-fill-color: rgba(175, 192, 227, 0.230469); -webkit-composition-frame-color: rgba(77, 128, 180, 0.230469); ">-Wayne</span></div> <div><span class="Apple-style-span" style="-webkit-tap-highlight-color: rgba(26, 26, 26, 0.292969); -webkit-composition-fill-color: rgba(175, 192, 227, 0.230469); -webkit-composition-frame-color: rgba(77, 128, 180, 0.230469);"><br> </span></div> </div> <div><br> On Mar 24, 2016, at 9:40 PM, ACCRS HO Scale <<a href="mailto:accrs-ho@mail.accrs.org">accrs-ho@mail.accrs.org</a>> wrote:<br> <br> </div> <div><span>Message From: Gary Lewis <a href="mailto:glgslewis@comcast.net">glgslewis@comcast.net</a></span><br> <span></span><br> </div> <div> <meta name="Generator" content="Microsoft Word 14 (filtered medium)"> <style></style> <div class="WordSection1"> <p class="MsoNormal">Folks,<o:p></o:p></p> <p class="MsoNormal">There were a reasonable number of folks running trains last Friday night. However, it became difficult to track them when the occupancy light system went dead. Not being an electrical whizz-bang, I don’t have a clue as what component caused the problem. Garran thought it might be a relay, but then the question was “do we have any spares”? Bottom line is that we need someone with knowledge about the system to troubleshoot it and get it back on line. Do we have any volunteers? It’s surprising how difficult it is to dispatch trains blind! <o:p></o:p></p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">Gary <o:p></o:p></p> </div> </div> <div><span>_______________________________________________</span><br> <span>Accrs-ho mailing list</span><br> <span><a href="mailto:Accrs-ho@mail.accrs.org">Accrs-ho@mail.accrs.org</a></span><br> <span><a href="https://mail.accrs.org/cgi-bin/mailman/listinfo/accrs-ho">https://mail.accrs.org/cgi-bin/mailman/listinfo/accrs-ho</a></span><br> </div> </body> </html>
