Hi All. I bought a radio remote system where the remote has an A and B button. It i s a momentary for both buttons on the key fob and the receiver box has two relays A and B.
Press Remote A and Relay A latches. Press Remote A again and Relay A un-latches.
Same for B button and B relay.
I want to use this as a gate opener using an old C-Band dish positioner tha t is rated for 2000-lbs max at 36vdc and 18" travel. I am using a 12v car b attery (solar panel charging) and a 18A Boost controller for the 36vdc and that part all works fine when I am holding wires to the battery.
The positioner has two cams inside for actuating two cherry limit switches that can be NO or NC (three tabs) at each end of the stroke. One cam/switch for fully out and one for fully closed.
I can set the thing up mechanically so that the gate is fully open or fully closed when each switch trips.
I am having trouble designing the wiring to use button A to open the gate t hen button B to close it. I do not want to have to press A to get it starte d then wait until it is fully open and then press A again to un-latch the A relay as I think the limit switch can do that.
But I am stuck with just where and how to open the 12v with the limit switc h so that it will still start up when button B is pressed to close the gate .
Could someone please help me out with a schematic on how to do this?
Thanks
