I’m looking to do a similar thing that you’re doing: have toggle switches to control front/left/rear jacks and do away with controller and touchpad (I’m using LevelMatePRO for levelling). I also want to be able to retract the jacks individually, not all together. I actually want to go a bit further and hook this up to my panned “smart rv” system: all controlled via iPad or cellphone, but that’s another topic altogether.
I got stuck at a campground with no power to the touchpad and applied 12v to front/left/rear valves to raise them bypassing the controller/touchpad. I’m still trying to determine the underlying problem for that one.
I’m just wondering why there is a dump valve. By applying 12v to each of the valves they retracted beautifully, I never applied 12v to the dump valve.
Do you happen to have a hydraulic schematic that shows all 4 valves and how they are hooked up in combination with the pump? Is the dump valve there to bypass the pump when raising the jacks?
I’ve attached a screenshot of a PG manual I found which indicates that the dump valve should be energized when raising the jacks. Note the text by “Pin 4”: “...Output to dump valve. Energized with +12vdc when the "retract all jacks" button is pushed
...”. Maybe that will speed up the raising of the jacks?
here’s the URL for the document:
In your case I think the “roadside rear leg” DPDT toggle switch should be wired as follows:
- Pole 1: send 12v to “roadside rear leg” solenoid valve both on “up” and on “down” (pin 5)
- Pole 2: on “up” (raise) send 12 v to dump solenoid valve (pin 4); on “down” (lower) send 12v to motor solenoid. (Pin 3)
This way you have 3 toggle switches with “up/down” controlling front/left/right jacks independently.
