AUTO-SETUP TYPE
STEPS OF AUTO-SETUP
3: Upper seal spring
+
Stroke specified
1) The stem goes down toward the lower-end side by the specified stroke length.
(Auto-setup is interrupted if the valve contacts the seat surface before reaching the specified
stroke length.)
2) The output stem goes up until the valve contacts the seat surface.
(Auto-setup is interrupted if the valve reaches the upper-end before it contacts the seat surface.)
3) The stem further compresses the seal spring upward from the seated position by the set amount.
If no error occurs, the positions reached in step 2) and step 4) are saved as the lower-stop posi-
tion and the upper-stop position, respectively.
Note: If the specified stroke distance cannot be secured, the positions reached in step 1) and step 3)
are saved as the lower-stop position and the upper-stop position, respectively.
4: Lower & Upper seal
springs
1) The output stem goes up until the valve contacts the seat surface.
(Auto-setup is interrupted if the valve reaches the upper-end before it contacts the seat surface.)
2) The stem further compresses the seal spring upward from the seated position by the set amount.
3) The output stem goes down until the valve contacts the seat surface.
(Auto-setup is interrupted if the valve reaches the lower-end before it contacts the seat surface.)
4) The stem further compresses the seal spring downward from the seated position by the set
amount.
If no error occurs, the positions reached in step 3) and step 5) are saved as the upper-stop posi-
tion and the lower-stop position, respectively.

AUTO-SETUP OPERATION DESCRIPTION
• Turn SW-8 to ON to switch from Automatic Operation mode to Manual Operation mode.
(If SW-8 is kept OFF, control by input signal takes priority over Manual operation.
Turn ON to enable the Auto-setup by Manual operation.)
• Press UP/CCW / DOWN/CW button slightly to move the output stem upward/downward.
Stop pressing the button to stop the output stem at the position.
Press the button to move the output stem approx. 2 mm in the middle direction from upper/lower-end side (The moving
distance is no problem with approximate).
• Turn SW-7 ON and OFF to move to Auto-setup mode. The PSP starts determining the stop position with following proce-
dure automatically.
Check the output stem visually as well.
E.g. The valve closes on downward.
1) The output stem automatically moves downward and stops on the valve seat surface.
2) The output stem automatically moves upward and stops at the position of initial setting.
3) Contracts 0.1 mm from seat surface of valve seal surface (contraction can be changed by the PC configurator software).
4) Recognizes the total distance of downward seat position (include contraction) and initial position of upper-end as 100%,
and completes Auto-setup.
5) Turn SW-8 to OFF to switch to Automatic Operation mode. The output stem moves to the position of the signal, if the
input signal is applied. DO NOT touch the output stem and around to not to stuff your fingers and hands.
• Contraction is set to “0.1 mm” for initial.
This can be changed by the PC configurator software or PU-2x with the range of 0.1 to 1.0 mm (0.1 to 0.5 for 1500N) by 0.1
mm.
• Full-closed position can be adjusted by the UP/CCW / DOWN/CW button (operation distance fine adjustment).
Use to re-adjust the closing position by moving the output stem downward from Auto- setup position to stop leaking.
Turn SW-8 from OFF to ON to enable manual operation (If SW-8 is kept OFF, control by input signal takes priority over
Manual operation).
Adjust the position of the output stem by UP/CCW / DOWN/CW button.
Perform the following procedure after position adjustment.
<After completion of lower-end position adjustment>
Turn SW1-5 OFF -> ON -> OFF to set upper-end position newly.
<After completion of upper-end position adjustment>
Turn SW1-6 OFF -> ON -> OFF to set lower-end position newly.
