The safety beams for that motor are pulse type (governed) beams not relay based. Which limits there usefullness as a controller. They are a two piece unit, one transmits and one recieves. These beams are brand specific, ie they will not work with other brands. I keep these in stock, but you can get them on ebay. When I have used pe beams in an observatory I usually use them to detect the scope in the parked position rather than trying to detect if the scope is obstructing the roof, the former works 100% the latter works some of the time.
There is only one sectional operator that I know (my business goes through around 800 garage door operators per annum, so I check out a lot of different brands) of that uses seperate input commands for up and down, but in my opinion is a piece of crap. Which is why I use a seperate motor controller.
