9.3.2 Adding and replacing IQ sensors
Inactive datasets of
IQ sensors
If an IQ sensor is removed from the system, its settings remains stored
in the DIQ/S 182 XT-4-MOD as an inactive dataset. A dataset contains
the following information:
 Serial number of the IQ sensor (and, with it, the type of sensor)
 Display position
 All sensor settings
 All characteristics of the link with an output.
If no suitable inactive dataset is available, a newly connected IQ sensor
is recognized and added automatically.
Note
The DIQ/S 182 XT-4-MOD can display and administrate up to four
main measured parameters. If necessary, an inactive dataset has to be
erased to be able to add a new sensor.
Note
The current calibration data of the IQ sensor is always stored in the
sensor. If an IQ sensor is connected that is ready for operation and
calibrated, this can be used immediately without the need for
recalibration.
Note
To erase inactive datasets, see page 5-3.
If an IQ sensor is connected to the system when an inactive dataset is
present, the following cases are possible:
Case 1:
The serial number of the
IQ sensor is identical with the
serial number of an inactive
dataset. The connected IQ sensor is
automatically assigned to the
inactive dataset and starts to
operate again.
Example: Maintenance or repair.
This mechanism ensures that all
IQ sensors retain their settings
and links if an IQ sensor was
removed for maintenance, or if
the system was temporarily
switched off.
