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.
Case 2:
The type of sensor is identical
with the type of sensor in an
inactive dataset (or several
inactive datasets), but the serial
numbers differ. Operator intervention is required
here. The connected IQ sensor
can:
– be assigned to the inactive
dataset (or one of the inactive
datasets).
Example: Replacing an
IQ sensor.
Make sure that the substitute
sensor has at least the
software status of the inactive
IQ sensor.
– be included as a new module
in the list of the sensors.
The operating sequence to do
this is described below.
