I am using a unit that has board issues that negate drive unit. I am just using it to lift up and down in a fixed position. When I start it, it goes through tests and comes back with a wrench. It has gate on display when I try to throttle. Won't go up and down. I don't know what the two dots below the lift diagram on the control panel mean. Left one stays lit green after startup, but the right one blinks orange and then goes off. I am loading a pic. I will try to load a slo mo of startup sequence. Which one is showing correctly? What are those dots? How do I cheat the gate check? Which unit in back is in charge of this gate clearance? Can I install a jumper? How do I load a pic? I don't know how to pull a fault code, if possible on this model?
