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 55) with screw driver
(5 mm) in direction of arrow, thereby observe LED V22 (figure 54).
Start of stepping mode in direction OPEN is set correctly if the LED chan-
ges 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 55) with screw driver
(5 mm) in direction of arrow, thereby observe LED V21 (figure 54).
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 55) with screw driver
(5 mm) in direction of arrow, thereby observe LED V22 (figure 54).
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 55) with screw driver
(5 mm) in direction of arrow, thereby observe LED V21 (figure 54).
End of stepping mode is correctly set if the LED changes from on to off
(see sketch on the left).
