General description, see page 13 (Operating modes).
3 .5 .1 2-point operation
Operating mode 1
In idle state (DI 1 with no signal), the actuator is in “low”
position (“low” position may also be 0° = “closed” posi-
tion).
If a signal is applied to digital input DI 1, the actua-
tor moves to “high” position within running time t
1
.
When the signal at digital input DI 1 drops, the actuator
moves back to “low” position within running time t
2
.

If the signal at digital input DI 1 is deactivated before
“high” position is reached, the actuator moves directly to
“low” position within the percentage time of t
2
.
The actuator operates in high/low (high/closed) inter-
mittent mode.
Possible parameter sets for this operating mode:
P68017, P68018 and P68019, see page 45 (Param-
eter sets).
