Overview The MIQ/IC2 module provides two 0/4 ... 20 mA current inputs for the
IQ S
ENSOR N ET . Each current input appears in the measured value
display, the Edit list of sensors overview and the Settings of sensors
and diff. sensors menu.
Each current input is treated like a sensor ("current sensor") by the
IQ S
ENSOR N ET and has a separate setting menu.
On initial commissioning, only current input 1 is registered on the
IQ S
ENSOR N ET . The measured value display indicates the value of the
current at current input 1 in mA.
The correlated measured value (display value) is displayed without any
designation of Unit and Measured parameter and, in the delivery
condition, is identical with the current value (default setting).
After the display values at the measuring range limits have been set
and the Unit and Measured parameter have been specified, the corre-
lated measured value corresponds to the measured value of the sen-
sor, e.g. of a DO sensor:

Activate current input 2 in the Settings of sensors and diff. sensors
menu of current input 1. The setting menus of both current inputs are
identical except for the activation of current input 2.
If the physical input current range is exceeded, OFL is displayed
(measuring range exceeded or undercut).
Note
The general operating principles are given in the system operating
manual or in the component operating manual of the terminal compo-
nents.
