6. PARAMETER DESCRIPTION
6.1 Parameters
With the exception of parameters that were specified
by the customer upon ordering, all of the internal
parameters will initially be set to default values.
Actions such as the modification of display details can
then be carried out whenever necessary.
For F OUNDATION Fieldbus protocol, please refer to IM
01E20F02-01E.
For PROFIBUS PA protocol, please refer to IM
01E20F12-01E.
IMPORTANT
Make sure to keep the instrument’s power on at
least for 30 seconds after you set the param-
eters. If you turn the power off immediately after
the parameters are set, the settings will be
canceled.
NOTE
In order to ensure that correct flow rate data can
be acquired, it is crucial that the nominal size,
flow rate span, and meter factor of the combined
remote flowtube are set. In cases where a
remote flowtube is ordered at the same time as
the AXFA14, or where the AXF integral flowme-
ter is ordered, the nominal size and meter factor
will be set upon shipment from the manufactur-
ing plant, and these will not require additional
setting. If the AXFA14 is ordered separately, the
default value will be set for the meter factor;
accordingly, it will be necessary to change this
setting to the meter factor indicated on your
remote flowtube data plate.
If a flow rate span was specified upon ordering,
this will be set before shipment. If this is not the
case, however, it will be necessary for the
appropriate value to be set by the user.
