Programming of Pneumatics

[Ben Piecuch]

I searched and found a couple threads related to this, but no one gave any solid answers. Therefore...

We are trying to use a momentary switch on our control board, to control a pneumatic cylinder. We have tried both single and double solenoids, so far with no luck. What we are attempting to do is this.

The cylinder is in one position (extended or compressed.) The driver hits the momentary switch once, and the cylinder changes position to the opposite extreme and holds. To bring the cylinder back, the driver hits the momentary switch once again, and the cylinder returns and holds.

Pretty simple, but we have run into several issues including hysteresis, the cylinder not returning on the 2nd press of the button, etc... Unfortunately, I'm not the programmer, so I don't have the actual code we've been working with. Does someone out there have a simple way to execute this command?

Thanks,
