I'm building a device that uses a rotary actuator(RA) to rotate a part180 degrees. I have a 5 port, 2 position air control valve that I wish to use to direct the air to the actuator. The control valve(CV) is actuated by a 24vdc signal. I can signal the right side of the CV and get air to the rotary actuator causing the RA to rotate CCW. If I send the signal to the left side of the CV the RA rotates CW. The RA has two position sensor switchs. One that closes at full CW and one that closes at full CCW (or at 0 degrees and 180 degrees).
I attempted to wire up the device and when I applied power the RA kept shuttling CW/CCW/CW/CCW. Very impressive but not the desired action.(If anyone very needs to build an air powered wind shield washer let me know, I have the circuit all worked out).
I have a 24vdc signal coming from a clamp solenoid on the main part of the machine. What I need, is a 24 VDC DPDT switch or relay that when the clamp solenoid receives the unclamp signal, the DPDT switch or relay closes one set of contacts allowing current to go to one side of the CV and when it receives the next unclamp signal the DPDT Switch or relay opens the first set of contacts and closes the second set of contacts allowing the current to the other side of the CV. This action of opening one set of contacts and closing the other with just 1 24vdc signal is what I am trying to work out.
I any of you know of a simple and bullet proof way to accomplish this, please let me know.
Thanks Greg Postma
