SW1-4 : OFF

SW1-4 : ON

To fine-adjust the position of the output stem:
Press [UPPER] or [LOWER] button to move the output stem 
upward or downward.
The output stem keeps moving while the button is pressed and 
stops as the button is released.

Press [UPPER] or [LOWER] button once to move the output 
stem upward or downward by the specified distance.

Moving Distance (approx.)

Setting

0.05 mm

Standard EX-factory setting

0.02 mm

Selected on PU-2x

0.1 m

Selected on PU-2x

For example, when the moving distance is set to 0.05 mm, 
pressing the button 10 times moves the output stem by approx. 
0.5 mm.

To complete the fine adjustment:
<Lower-end side>
Turn SW1-5 from OFF to ON, then to OFF again to newly set 
the lower-end position.
<Upper-end side>
Turn SW1-6 from OFF to ON, then to OFF again to newly set 
the upper-end position.

To complete the fine adjustment:
<Lower-end side>
Turn SW1-5 from OFF to ON, then to OFF again to newly set 
the lower-end position.
<Upper-end side>
Turn SW1-6 from OFF to ON, then to OFF again to newly set 
the upper-end position.

Note) 

 

In Manual Operation mode, an alarm will not be triggered even if the output stem is locked. 
Thus, perform button operation carefully while watching the scale markings at 1-mm intervals, and DO NOT move the 
output stem to an extent that will compress the seal spring by more than 1 mm.
Basically, it is safe to move the output stem by the factory-set amount (spring contraction amount can be specified when 
ordering; 0.1 mm if not specified).

 

DEADBAND SETTING

Deadband can be configured on PU-2x or via Modbus communication. 
Refer to “13.8. Basic setting” for details.

Standard EX-factory setting: 0.3% *

 

RESTART LIMITING TIMER

Restart limiting timer can be configured on PU-2x or via Modbus communication. 
Refer to “13.8. Basic setting” for details.
Standard EX-factory setting: 1.5 sec. *

* The standard EX-factory setting will be applied unless otherwise specified when ordering.
