Dear all,
Im working on a project for my niece who has CP. Basically where I live I can't get my hands on a Bruan UVL wheelchair lift. So I built one. I basically got a 12v KTI hydraulic pump (dual double action)so it has both up/down, in/out function. I got all parts together and succeeded in getting the basic operation required. However my skills lack in electrical setup. So I would like to put limit switches to control certain points. Like when to stop when it is fully out, in stow position and in van level position. My question is how to wire the switches. Where does it get its power from. I don’t want to start messing with the main control wiring. Also when this is fixed in place and the limit switch works and stops the lift when it is out. How do I get it to work again and go down or up if I technically have given a stop function. Doesn't make sense to me. So I'd appreciate all the help I can get. Thanks in advance
