The valve has to be applied in 5/2 configuration. To
achieve that position the conversion plate between
spool valve and actuator as shown in the image. Both
ports 2 and 4 of the valve should be visible when
placing the conversion plate on the valve.
8.6.1 Clockwise pump operation
Pressurizing port 1 on the spool valve without
electrically activating the valve will result in a counter
clockwise rotation of the actuator towards "open"
position. This brings the pump in pumping position.
Pressurizing port 1 on the spool valve and electrically
activating the valve will result in a clockwise rotation
towards of the actuator "closed" position. This brings
the pump in CIP position.
Make sure the valve block is connected to the actuator
body in such a way that ports 2 and 4 of the valve block
are connected to ports B and A of the actuator body
respectively.
