stusviews Posted April 21, 2016 Posted April 21, 2016 This is the voltage flow when the I/O Linc relays are Off (N/O not connected to COM. N/C connected to COM). Power enters at the left. The actuator (not shown) is connected to the COM terminals. This is the voltage flow when the I/O Linc relays are On (N/O connected to COM. N/C not connected to COM). The polarity to the actuator is reversed. With one I/O Linc On and the other Off, both actuator wires are connected to the positive wire only or the negative wire only in which case the actuator is actually not connected to the power supply at all.
jerlands Posted April 22, 2016 Posted April 22, 2016 Got it! One IOLinc needs to be On in order for power Off to actuator. Jon...
stusviews Posted April 22, 2016 Posted April 22, 2016 That's it. Both I/O Lincs Off move the actuator to it's extended position and both I/O Lincs On move it to the the retracted position (you can reverse that action by swapping the COM wires to the actuator). The limit switches on the actuator cut off power automatically when the extended or retracted limit is reached. To stop the actuator at an intermediate position, set one I/O Linc to On and the other to Off. Which is On and which is Off doesn't matter as long as they're not both in the same state, On or Off.
jerlands Posted April 22, 2016 Posted April 22, 2016 It took me a while but I see now It does go against some instinct I have for On to do that Jon...
stusviews Posted April 22, 2016 Posted April 22, 2016 The only reason that On retracts and Off extends the actuator in the schematics is because I like to start with red (+) at the top and the I/O Lincs in the Off position. That's easily corrected by reversing the polarity of the source or the polarity of the actuator
jerlands Posted April 22, 2016 Posted April 22, 2016 I was referring more to the power off state but I understand your point about extension and retraction. Jon...
Killzone1023 Posted April 22, 2016 Author Posted April 22, 2016 Thanks everyone for the input. I think I bit off a little more than I can chew after reading some of your responses. When you have to google what things are it may be over your head. Lol I since have spoke to some one dif forum and found the exact way to accomplish my goal Without using a actuator or wiring diodes. I may try this in the future, if my new idea doesn't quite work the way I want. @stusviews your idea seems the simplest and if this new thing does not work I'll be doing exactly what you said and will upload pics of finished product. Thanks again
