This menu allows the set-up of different functions relevant to
the display itself. The menu driven structure will guide you
through the choice of some functional aspects as the display
language and contrast. Moreover, it is possible to choose in
details what you want to see on the display: one or two lines
with or without bargraph. Inside this menu there is the
possibility of setting a protection password (security) and the
display scaling (linearization type, unit, LRV, URV). Display
revision number available.
This menu allows the parameterization of the process alarm.
The menu driven structure will guide you through the choice of
the fail safe functions such as the saturation limits, the fail level
(upscale or downscale) and the fails safe type which is set as
software at the factory. Software fail safe type means that fail
direction can be set via DD, DTM or display. If hardware is
selected, the software settings are disabled and user has to
use the dip switches on the electronic board.
This menu allows the local calibration of the instrument. The
menu driven structure will guide you through the choice of
pressure sensor trimming (low or high), the output setting (set
to 4 or 20 mA) and at the end you can reset these parameters
(to factory sensor trimming, to user sensor trimming or to
factory output trimming).
This menu allows the set-up of the on-board totalizer. To have
the totalizer running, a flow unit must be selected in advance
and then it must be placed in "run" status. Different modes can
be selected:
Normal: standard totalization for the forward flow rate.
— Batch: this kind of setting can be used on totalizer 1 only.
You need to set a pre-defined value. When totalization
reaches that value, the totalizer will re-start from zero and
the batch number increases by one.
— Forward/Reverse: totalizer 1 will monitor the forward flow,
whereas totalizer 2 the reverse flow.
— Forward – Reverse: the value you will see on the display
by applying this mode is the difference between forward
and reverse flow rate.
— Forward + Reverse: the value you will see on the display
by applying this mode is the sum of forward and reverse
flow rate.
Another important setting is the conversion factor which is to
be used if the totalized unit is not directly related to the scaled
one (i.e. m /h totalized in kg). Conversion factor is basically a
3
multiplier.
User will be able to add/ change/delete the password as well
as to reset all totalizers.
This menu allows you to monitor diagnostics messages related
to pressure variable, output current, output percentage, scaled
output, static and sensor pressure. The menu driven structure
will also guide you through the loop test (set 4 and 20 mA and
set the output value).
This menu gives you all information about the device. The
menu driven structure will show you what is the sensor type,
the hardware and software revisions, the high and low sensor
limits as well as the minimum applicable span.
The last section of this structured and driven menu gives you
the possibility of changing the communication tag and the
MULTI-DROP mode with HART address numbers of the device
From software release rev. 7.2.1 it also allowed to select the
HART revision between HART 5 and HART 7.
