Selecting the
Direction of
Operation
• With normally-closed valves, "direct-acting" means that with a 0 Vdc signal input, the valve
is closed.
• With Normally-open valves, "direct-acting" means that with a 0 Vdc signal input, the valve
is open.

Control
Check the wiring for proper connections.
NOTE: The valve body assembly determines the complete assembly action.
Table 3. Table 4.
Setting the Stroke Limit Control
Setting the Sequence Control
The rotary switches LO and UP can be
used to apply an upper and lower limit
to the stroke in increments of 3% up to
a maximum of 45%.
The rotary switches LO and UP can be used
to determine the starting point (Start) or the
operating range of a sequence (Span).
