22.2 Setting start and end of stepping mode via DUO limit switching (option)
Start and end of stepping mode can also be set via external switches
(use potential-free contacts).
Direction OPEN, first normal operation then stepping mode .
Run valve in direction OPEN to the desired start of stepping mode.
.
Press down and turn setting spindle K (figure AM) with screw driver
in direction of arrow, thereby observe LED V22 (figure AL).
Start of stepping mode in direction OPEN is set correctly if the LED changes
from off to on (see sketch on the left).
Direction CLOSE, first normal operation then stepping mode
.
Run valve in direction CLOSE to the desired start of stepping mode.
.
Press down and turn setting spindle G (figure AM) with screw driver
in direction of arrow, thereby observe LED V21 (figure AL).
Start of stepping mode in direction CLOSE is set correctly if the LED changes
from off to on (see sketch on the left).
Direction OPEN, first stepping mode then normal operation
.
Run valve in direction OPEN to the desired end of stepping mode.
.
Press down and turn setting spindle K (figure AM) with screw driver
in direction of arrow, thereby observe LED V22 (figure AL).
End of stepping mode is correctly set if the LED changes from on to off (see
sketch on the left).
Direction CLOSE, first stepping mode then normal operation .
Run valve in direction CLOSE to the desired end of stepping mode.
.
Press down and turn setting spindle G (figure AM) with screw driver
in direction of arrow, thereby observe LED V21 (figure AL).
End of stepping mode is correctly set if the LED changes from on to off (see
