Position 0
DIP 1
Set value input: voltage, V or current, mA?
current, mA
voltage, V
DIP 2
Set value input starting at 0 V / 0 mA or
2 V / 4 mA?
2-10 V / 4-20 mA
0-10 V / 0-20 mA
DIP 3
Analogue output starting at 0 V / 0mA or
2 V / 4 mA?
2-10 V and / or
4-20 mA
0-10 V and / or
0-20 mA
DIP 4
Direction of control action: valve closed with
drive spindle extended or retracted?
Drive spindle retracted
→
valve closed
Drive spindle
extended →
valve closed
DIP 5
Current position of the actuator is saved as
additional switching position "2EZ-1". See
wiring diagram, page 21.
from 0 to 1 →
save "2EZ-1"
= 2%
DIP 6
Current position of the actuator is saved as
second additional switching position "2EZ-1".
See wiring diagram, page 21.
from 0 to 1 →
save "2EZ-2"
= 98%
DIP 7, 8, 9
These 3 DIP switches define the function:
linear / split range / 11-point / inverted

DIP 12
Starts initialization run.
Set back to 0 after initialization
(s. section 8.5.2)
from 0 to 1 →
starts initialization run
N↔S
Selects normal or safety mode
position "S"
= safety mode
position "N"
= normal mode
