InstructIon and operatIng manual
9.1.9 out 4-20 ma
This routine is only available if the Ain/Aout
card is present� With this card the ICON 2000
is provided with a 4-20 mA analog input and a
4-20 mA analog output�
The 4-20 mA output can be configured to
provide a current proportional to either
“position” or “torque”� The polarity option
allows to reverse the relationship between the
present position or torque and the 4-20 mA
output signal, according to the following
diagrams:

NO to change it, then press yES�
configuration procedure
• Move the local selector to OFF and then
simultaneously press OPEN and STOP� Select

DELAy is correct (from 0 to 255 sec), or press
NO to change it, then press yES�
9.1.10 interlock
The interlock inputs can be used to inhibit the
actuator movement in open or close direction�
The controls are momentary, the inhibit
action continues until the relevant signal is
present� The interlock controls work when the
local selector is in LOCAL or in REMOTE� The
ESD control overrides the interlock controls�
The following options can be configured:
-
Interlock OP:
active when signal is PRESENT, active when
signal is ABSENT, no action (Off)�
-
Interlock CL:
active when signal is PRESENT, active when
signal is ABSENT, no action (Off)�
