IC 40 function > Standard operating modes 1 – 12
4.5.6 3-step operation with one or two digital inputs
Operating mode 6
Each of the 4 circuit combinations resulting from DI 1
and DI
2 determines precisely one actuator position:
Each signal change results in a new position setpoint for
the actuator. If the signals overlap (see t2), the actuator
moves to-wards “high”. If the signals do not overlap (see
t5), the actuator moves towards “closed”.
Various modes of operation can be implemented with
this operating mode.
Control via one digital input
DI 2 with no signal:The actuator operates in low/closed
intermittent mode via digital input DI 1.
DI 1 with no signal:The actuator operates in middle/low
intermittent mode via digital input DI 2.
