Scott,
I've only got a traction print here with me, hope it's about the same...
"seems to me that DC, and DO will both be picked at the same time as soon as the door open limit makes and puts the 2 side of the line on terminal 36. both relays would have to be picked, since the cpu is outputting DCF to close the doors, then the door open limit makes and since DOF is shorted, DO would pick up, but, the cpu would not have any way of knowing that D0 relay was also picked, it can not tell that the DOF triac is shorted"
Hmm, lets' see....DOF triac is shorted, so any time the Door Open Limit is made, DO relay picks...ok...And on this print, DOX is in parallel with DOF, so you get that one in, too..
DOX n/c is in series with the DC relay coil, so when the doors start to close, as soon as the door open limit closes, DOF and DOX pick due to triac DOF being shorted, and DOX n/c opens, dropping the DC relay. So DC and DO aren't in at the same time
Do I get a star on my forehead?
