Re: Mulit-postioning with pnuematics this year?
We are using one double solenoid and one single and can stop the cylinder at almost any location. It does not stop instantly but there is very little creep after the switch is released.
We have a three position rocker switch wired to both solenoids.
When pushed to the right, the switch opens the double solenoid in the extend direction and opens the vent on the single solenoid to allow the cylinder to move. When released, the rocker goes to the center position which closed the single solenoid and the cylinder stops.
When the switch is pushed to the left, the same things happen only the other side of the double solenoid opens to retract the cylinder.
By simply tapping the rocker, the cylinder can be stepped up or down to an infinite number of positions.
We originally thought we needed two separate switches, one to select the direction on the double solenoid, and one to release the exhaust air through the single - but the electronics team found a way to do it with one switch.
