6.10 A12 plausibility checks
When configuring the device, a number of complex "cluster" checks are run internally on the
proposed configuration in order to make sure it is valid. Thus when saving a configuration the
device might raise an error like this: "Failed E01", which indicates an error cluster number.
In this case please consult the indicated cluster number in the following table to find out which
parameters are affected.
You may also want to enter in the quick setup menu "A12 Cluster Checks" and check each
setting in the affected "cluster" submenu.
No. Name
Explanation of plausibility checks
01
Sensor
Configuration /
Fluid
After changing fluid, operating density or operating temperature the device checks whether
the measurement variables configured at the device’s outputs are still valid (HART
®
variables, frequency output, pulse output, status output, limit switch, local display and flow
totalizer). Also their configured ranges are checked.
02
Medium
When selecting the medium the device checks whether the measurement variables
configured at the device’s outputs are still valid (HART
®
variables, frequency output, pulse
output, status output, limit switch, local display and flow totalizer).
Additionally the configuration of temperature sources and pressure sources is checked.
03
Meter Type
When changing the meter type the device will check whether the measurement variables
configured at the device’s outputs are still valid (HART
®
variables, frequency output, pulse
output, status output, limit switch, local display and flow totalizer).
It also checks if the currently selected medium is supported by the new meter type as well
as the configuration of temperature sources and pressure sources.
04
Temperature /
Pressure
Checks configuration of temperature sources and pressure sources.
05
Current output /
primary HART
variable
Checks if selected measurement variable is valid. Also checks limit settings for 0% and
100%.
06
Frequency output /
Secondary HART
variable
Checks if the frequency output/secondary HART
®
variable is valid.
Also checks if the selected measurement variable is available in this context and if its range
is valid.
07
Current input /
Tertiary HART
variable
If the current input is selected to provide temperature or pressure measurement data, the
device checks the configuration of temperature sources and pressure sources.
It also checks if the current input range (4 mA / 20 mA) is valid.
08
Quaternary HART
Variable
Checks if the measurement variable configured as quaternary HART
®
variable is valid.
09
Flow Totalizer
Checks if the measurement variable selected for the flow totalizer (volume flow, standard
volume flow, mass flow) is valid. Also checks configuration of the HART
®
variables, limit
switch and local display.
10
Measurement
Display Pages
Checks if the measurement variables selected on both measurement display pages are
valid.
If a bar graph is displayed its ranges are also checked.
11
Gas Mix Total
If a gas mixture is selected as medium, the device checks if all individual gas components
add up to 100%.
12
HART Catch
Variable
(Temperature /
Pressure)
If temperature or pressure data input is provided by HART
®
, the device checks if the "Slot
Number" fits in with the "Capture Command".
