6.10 Plausibility Checks Menu A12

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 the Quick Setup menu A12 and check each setting in the affected
"cluster" submenu.

Explanation of Plausibility Checks
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/pulse/status output, limit switch, local display and flow totalizer). Also their
configured ranges are checked.
When selecting the medium the device checks whether the measurement variables
configured at the device's outputs are still valid (HART variables, frequency/pulse/status
output, limit switch, local display and flow totalizer).
Additionally the configuration of temperature sources and pressure sources is checked.
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/pulse/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.
Checks configuration of temperature sources and pressure sources.
Checks if selected measurement variable is valid. Also checks limit settings for 0% and
100%.
Checks if the binary output/2nd HART variable configured as frequency output, pulse output,
status output or limit switch is valid.
Also checks if the selected measurement variable is available in this context and if its range
is valid.
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 ranges (4mA / 20 mA) are valid.
Checks if the measurement variable configured as 4th HART variable is valid.
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.
Checks if the measurement variables selected on both measurement display pages are
valid. If a bar graph is displayed its ranges are also checked.
If a gas mixture is selected as medium, the device checks if all individual gas components
add up to 100%.
If temperature or pressure data input is provided by HART, the device checks if the "Slot
Number" fits in with the "Capture Command".
