Dude you're awesome! You should make some more videos. I have electrical background and just from three of your videos I am able to grasp more of the ts 1 and twos thank you!
Adrian Taylor. Out here in California, the RxR cabinet has a normally closed (N/C) contact that is tied into the TS cabinet (332). Once the train comes it opens up the contact putting a Railroad preemption call to the 2070 controller. Depending on how the traffic engineer has the controller program it will either go into Limited service or four way flash. 🚦🚅🚨😄
We tie the RR wires to a 120VAC relay in the signal cabinet. When the RR triggers it closes the relay to trigger the preemption for the RR crossing. Some RR will park at the intersection so we cycle the non conflicting phases to move traffic during preemption.
I have a tech question... I have an old test board that runs on 120 volt S6 candelabra-base incandescent light bulbs. Those old light bulbs are getting harder to find especially here in California where they are phasing them out. When I tried to replace the incandescent bulbs with LED lamps, the LED's stay on constantly, in a dimly lit state.. They work just fine and go to full brightness when they receive an input from the controller, but instead of turning off, they go back to that dim, constant ON state. My understanding is that in a TRIAC, there is a slight voltage leak that incandescent bulbs don't care about, but LED's apparently do. I tried wiring in load resistors which didn't help. Would you happen to know a work-around for this?
Have you tried moving to a different field terminal? How did you wire in the load resistors? You should have taken one leg of the resistor to the output of the field terminal and the other leg to the AC-. Double check your AC- bars and make sure they're all connected. One last thing.. If you pull the load switch out, does it stay dim?

The load switches with the In and Out are so much better than the potted load switches.
Great videos! Hope you keep making them, even simple stuff is great for those interested in getting into the field. Thanks so much.
Thank you! I'm sorry I'm inconsistent with posts but I usually make these videos on personal time and lunch breaks. I hope to keep it up.
Just saw these today on my job! Thanks
Keep'em coming in.👌👌👌
Also, I wanna know how technicians tie in a intersection with a railroad crossing.
Hope to get one of those videos.

Great video
Thanks!
How about a video explaining the detector rack
Thanks bro
In our traffic controllers we use 24 way load switches for the traffic lights
Essentially a solid state relay.
Very nice, can you cover the 210CMU.

@@streetsmartstraffic I'll give it a try. Thank you!
You’re welcome
Load Switches...the root of most evil in a traffic cabinet!!
Some say they run on smoke, because when you let all the smoke out they don't work anymore.
Is the the EDI 510 not showing output ?
I'd love to be a traffic signal technician
I'm a signals technician in Australia. It can be an interesting job. Hard on the back too.
