Each valve switching position isrepresented by a square.

The number of squares corresponds

to the number of switching positions.

Lines indicate the flow path,arrows show the direction of flow.

Shut-off positions are identified in theboxes by lines drawn at right angles.

The connections (inlet andoutlet ports) are shown by lineson the outside of the box.

Each current path must be

connected to the positive+ 24 V rail via a terminal.

Each current path must be

connected to the negativeO V rail via a terminal.

External elements, such as

switches, sensors andsolenoids are connectedvia one terminal per unit.

The connection point for+ 24 V and 0 V is to be
