![]() For my relays, this was blue and yellow (I'm afraid I don't have the relays present to check the numbered markings). Try connecting your 12V PSU to the relays two power leads such that you can hear it click.As for the relays, it is possible that the wiring harnesses are not color coded the same even if your purchased the same relay set.You'll want to do this to set the limits once your shades are up, but in the meantime it at least lets you know power is working. If after a few seconds, the motor sounds three beeps, it will go into a programming mode where you can set the limits of the rotation. If you still cant get any life out of the motor, try pressing and holding the set button hidden in the non-rotating side of the motor friction ring.The Rollertroll motors have an internal rotation counter and if you are at the end of the rotation, reversing power should get the motor to at least show some signs of life.If it doesnt, try reversing the connection to the motor and the power supply.I would try connecting the motor directly to one of the 12V PSUs to see if it turns normally without the complication of the relays.Try each component individually: make sure the motor is powered by the 12V PSU on its own and make sure the relay is powered by the 12V PSU on its own.There is an error in the digram: the white wire on my wire harness is normally open, not normally closed.I don't have a direct answer for you but I do have a few suggestions: I have to admit, this was the most complicated part of the endeavor. I'm sorry to hear that you're having difficulty with the wiring. Keep length in mind though and always test before you commit anything to drywall. Ethernet is cheap, easy to run and should be more than adequate for powering your motors. With one ethernet cable, you can pass power to four motors. If you are placing multiple motors near each other in a bank of windows, you might consider using ethernet to gang together different motors. The last thing you want is for your shade to somehow catch the wires and rip them out of the motor. Route the two motor wires through the mourning bracket and out of the way of any rotations. Make sure your mounting is level or your shades won't hang properly. If your distances are longer, RollerTrol suggests metal electrical conduit. I found enough inconsistency that I had to try several different pipes each time. I would probably take a motor mount to your home center and test the fit though. As for tubing, if your window distances are shorter (4' or less), SCH40 PVC pipe works rather well. The RollerTrol motors ship with mounting brackets that screw to your window frame and mount via a small metal flange. Mounting Mounting the motor is rather straightforward. I used automotive relays as they were easy to wire but certainly overkill. Any 12V SPDT relay should be more than adequate. 12V DC 2A Power Supply Relays Because we will be wiring both supplies to the motor at the same time, we need a way to break the circuit. I happen to have a bunch of 12V adapters around, so we're going to just use what is on hand. More advanced hobbyists can probably wire up a polarity reversing switch that only needs one supply. My solution will require two supplies for each shade. INSTEON Micro Module Power Supply Any 12V DC, 2A power supply will do. INSTEON does offer a dry-contact relay module, the I/O Linc, but you would need two I/O Lincs to control a single shade (one to control up, the other to control down). ![]() The only cumbersome thing is that the relays operate at 120V AC, not the 12V DC we need for the motors. ![]() One relay responds to an UP command, the other to the DOWN command. INSTEON recently released a new module, the Micro Open/Close controller which is essentially a dual-relay module. DC Motors Controller My home is controlled with INSTEON so, naturally, I have come to an INSTEON automation solution. They even have an included rotation counter so that the up and down limit on your shade is managed by the motor itself. The motors require 2A 12V DC power and can be reversed just by changing polarity. What you will need: Motors Tubular motors from are affordable (at least in the world of tubular motors for shades), relatively quiet and easy to work with. ![]()
