•DIP2 - Control signal:
ON: inverse
OFF: direct
•DIP3, 4 - Range setting:
See the table
•DIP5 - Control signal:
ON: I (mA)
OFF: U (V)
Note.
During changing position of DIP1 is performed calibration proces.
The actuator turns into left and right position. During proces leave
the button for manual control in position AUTO.
• Operation to set the DIP switches
