Ramsey Electronics RR1 manual

Wow that was fast! 20 steps for something as neat as this may not seem like a lot, but we are almost done building the kit!

Take a moment to go back through the steps you’ve completed and check the orientation of all the installed devices before plugging in the power. This will help you to avoid damaging any critical components by accident when you fire-it-up the first time (note: we are trying to avoid the “fire” in fire-it-up). Make sure to check all the capacitors for proper orientation, the micro-controller IC, as well as the rectifier diode and VR1.

‰21. The IR LED wiring offers you a bit of flexibility to custom match the RR1 to your application. You will need to determine how long of a wire you will actually need to fit the job at hand and then cut it to length. The 8 foot piece of wire that is supplied with the kit is more than enough for most of the common component cases available today (we didn’t want to include an entire 1000 foot spool with every kit either!). Leaving the wire length at 8 feet, even if you only need 4, may be a good idea. Take any extra wire and neatly coil it into a loop. You never know when someone will get the urge to re-arrange and you’ll need to extend the wire.

‰22. Trim both the red and black hook-up wires on each end to 1/4”. Tin all four ends with solder to prevent them from fraying.

‰23. Cut the 1/8” piece of heatshrink in half and slide a piece onto one end of the red wire. On the same end, slide the other piece onto the black wire. These will keep the leads of the IR LED from shorting together later.

‰24. Bend the leads of the IR LED outward in a slight ’Y’ formation to give yourself some space between the two leads to solder the hook-up wires.

‰25. Attach the IR LED to the hook-up wire by soldering the black wire to the Cathode (K) and the RED wire to the Anode (A). Use the end with the 1/8” heat shrink tubing in place so you can slide them over the junctions later. Look at the LED diagram of D1 for clarification if needed. A pair of needle-nose pliers work well to make small loops in the wire ends to slide the IR LED leads through. After you slide the leads through the loops, tighten them down so the IR LED leads are held in place for soldering.

‰26. Trim back the excess IR LED lead wire for a nice, clean assembly and slide the heat shrink tubing up and over the leads to the base of the IR LED. You may need to trim any sharp edges off of the solder joint before the tubing will slip over.

‰27. Install the other end of the Black wire into the J1 terminal jack closest to the corner (labeled BLACK) and the Red wire into the other hole (labeled RED). Use a small screwdriver to gently tighten the down screws.

FINISHED!!! Now we are ready to begin testing our handiwork!
