Dc motor reversing with my computer and relays.
I found another forum in here talking about dc motor reversing but lost it. I am working on a small project. Running a 90vdc motor with controller off a computer using control relays. I have the operation functioning with a DPDT switch. I want to be able to start my computer energizing a 3.3v or 12v control relay. Which will send my lift up til it hits a switch. When that switch is mated it signals another relay to complete the down motion of the lift when the computer is turned off. In the last operation I was wanting to put a digital timer for about 1 minute to verify that I have not just reset computer. I have drawn a drawing of my setup I would like but just dont know how to wire relays and switches to make this happen. Any help would be awesome. The drawing was done in word. Might have to zoom in on picture document. Thanks for everything , hopefully some one can help me.
