Exhaust in Solenoids

In the opposite position (activated), it reverses the cylinder action by sending pressurized air through port B to fill cylinder end B, while simultaneously emptying cylinder end A by connecting port A to an exhaust port.

We tested it out, and we have no control over any of the valves, even though we used the same code mentioned above and the solenoids are lighting up...
