IC 20 function
3.2 IC 20..E connection diagram
See page 70 (Project planning infor-
mation).
See page 76 (Technical data).
3 .2 .1 Continuous control
Following successful modulation
enable via terminal 5(OK), the
actuator reacts to the setpoint
specification (0 (4) – 20 mA,
0 – 10 V) via terminals 17 and 18.
The pre-purge and ignition positions
are controlled via terminals 1 and 2.
3.2.2 2-point step control
Connect voltage to terminals 1 and 3.
Set the DIP switch to 2-point step
control, see page 20 (IC 20..E DIP
switch).
If an input signal is applied to terminal
5(OK), the actuator opens. If no input
signal is applied to terminal 5, the ac-
tuator closes.
Terminals 17 and 18 for continuous
control are not required in the case of
2-point control
