Can you have a selector switch engage one set of directional valves on a machine that can have 2 automated cart dampers which share a motor?
Basically the first position on the switch means no set of valves are on, the second position for cart dumper 1 and the third position for cart dumper 2?
Here is a picture of the system:
The 3 4 contact block is a KA2 N.O contact and the 1 2 contact block is a KA3 N.C contact.
The joystick on the left is what energizes either the up solenoid or down solenoid of either machine 1 or machine 2. The selector is placed there to prevent all solenoids from being on at one time.
