Slide out control

I'll try again since the basic question is still; does anyone know what is the normal method for detecting the position of the slide-out especially the IN position. From what I have already described, there is obviously a lock-out in play here that prevents starting when the control perceives a condition of slide out. Again, the slide is not out, in fact, it is in and manual locks are in place. I want to troubleshoot this issue and would like a place to start. I have opened the slide-out control box. Some relays, integrated circuit components, etc. I don't see any obvious adjustment pots. The control was made for HR by Todd Engineering, but a quick internet search shows no commercial product they sell for RV slide-outs. If nothing turns up here, I may try to contact them and see if anybody has a clue.
