IC 40 function > Standard operating modes 1 – 12
4.5.9 2-point operation with switchover of the
running
times
Operating mode 9
Digital input DI 1 functions as a pulse input.
The actuator operates in high/low (high/closed)
intermittent mode via digital input DI 1.In idle state (DI 1
with no signal), the actuator is in “low” position (“low”
position may also be 0° = “closed” position).
The running times are switched over via DI 2.
Switchover of the running times may also occur during
movement of the actuator.
This function can also, for instance, be used for fast
movement to the pre-purge position, with
correspondingly slow running time for burner operation.
Possible parameter set for this operating mode: P
68025, see page 54 (Parameter sets).
