CAUTION
• In cases where the ambient temperature
exceeds 50°C (122°F), use external heatresistant wiring with a maximum allowable
temperature of 70°C (158°F) or above.
• Do not connect cables outdoors in wet weather
in order to prevent damage from condensation
and to protect the insulation.
• Do not splice the cable between the flowtube
terminal and the converter if it is too short.
Replace the short cable with a cable that is the
appropriate length.
• All the cable ends must be provided with round
crimp-on terminals and be securely wired.
• The signal cables must be routed in separate
steel conduit tubes 16 (JIS C 8305) or flexible
conduit tubes 15 (JIS C 8309).
• Always route the power and output signal
cables in separate steel conduit tubes, except
when the power supply voltage is 24 V and

NOTE
Conductors A and B carry the signal from the
electrodes, and C is at the potential of the liquid
(signal common). Shields SA and SB are kept
at the same potentials as the individual electrodes (these are actively driven shields.) This is
done to reduce the effect of the distributed
capacitance of the cable at long cable length.
Note that, since the signals from the individual
electrodes are impedance converted inside the
converter, errors will result if they come in
contact with any other component. Great care
must be taken in the cable end treatment.
(2) Excitation Cable/Power Cable/Output

NOTE
• For excitation and power cables, always use a
crimp terminal with an insulation cover.
• Use crimp tools from the manufacturer of the
crimp terminal you want to use to connect the
crimp terminal and cable.
• Use crimp tools that are appropriate for the
diameter of the cable to be connected.

4.4.3 Precautions for Wiring of Power Supply Cables
When connecting to the power supply, observe the
points below. Failure to comply with these warnings
may result in an electric shock or damage to the
instrument.
WARNING
• Ensure that the power supply is OFF in order to
prevent electric shocks.
•Ensure the protective grounding terminal is
grounded before turning the power on.
• Use insulating sleeve crimp terminals (for 4-mm
screws) for the power supply wiring and protective grounding wiring.
• To prevent electric shocks, ensure the electrical
wiring cover (transparent) is attached.
• Install an external switch or circuit breaker as a
means to turn the powe off (capacitance; 15A,
conforming to IEC947-1 and IEC947-3). Locate
this switch either near the instrument or in other
places facilitating easy operation. Affix a
“Power Off Equipment” label to this external
switch or circuit breaker.
4.4.4 DC Power Connection
When using DC power as the power supply for the
converter, give attention to the following points.
(1) Connecting Power Supply
IMPORTANT
Do not connect power supply with reversed
polarities.
L/+ terminal: connect +
N/– terminal: connect
IMPORTANT
Do not connect power supply with 100 to 240 V
AC or 100 to 120 V DC in the case of a 24 V
power supply version (power supply code 2).
It will give a damage to the converter.
(2) Required Power Supply Voltages
IMPORTANT
When using a 24 V power supply, the specification for the supply voltage is 24 V (–15% to
+20%), but the input voltage of the converter
drops due to cable resistance therefore it must
be used within the following ranges.

IMPORTANT
• As this is a transistor contact (insulated type),
give attention to proper voltage and polarity
when wiring.
• Do not apply a voltage larger than 30V DC or a
current larger than 0.2A in order to prevent
damage to the instrument.
• When input filter constant of the electronic
counter is large in relation to the pulse width,
the signal will decrease and the count will not
be accurate.
• If the input impedance of the electronic counter
is large, an induction noise from the power
supply may result in inaccurate counts. Use a
shield cable or sufficiently reduce the input
impedance of the electronic counter within the
electromagnetic flowmeter pulse output specification range.
• The active pulse output (Optional Code EM)
cannot be used in conjunction with the standard
pulse output.
• When the active pulse output (Optional Code
EM) is selected, do not be short-circuit between
the P+ and P– terminals to avoid damaging the
instrument.
• When the active pulse output (Optional code
EM) is selected, the range of pulse rate must
be set to 2 pps maximum.
• To avoid communication (BRAIN/ HART)
failure, it is recommended to use the shield
cable.

6. PARAMETER DESCRIPTION
6. PARAMETER DESCRIPTION
6.1 Parameters
With the exception of parameters that were specified
by the customer upon ordering, all of the AXFA11’s
internal parameters will initially be set to default
values. Actions such as the modification of display
details can then be carried out whenever necessary.
IMPORTANT
Make sure to keep the AXFA11’s power on at
least for 30 seconds after you set the parameters. If you turn the power off immediately after
the parameters are set, the settings will be
canceled.
6.2 Parameter Lists
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 setup. In cases where a
remote flowtube is ordered at the same time as
the AXFA11, the nominal size and meter factor
will be setup upon shipment from the manufacturing plant, and these will not require additional
setting. If the AXFA11 is ordered individually, the
default value will be setup 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 is 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 up by the user.
Parameter lists are comprised of the following items.

Description
Describes the parameter content.
The default value (as setup upon plant shipment).
If marked “(*)”, it indicates that the appropriate
setting has been made in accordance with
ordering information and data for a remote
flowtube to be combined.
The position of the decimal point within the data
range and also the allowed relocation range in
terms of places of decimals.
The units corresponding to the data range.
This item defines the range of data to be set for
numeric parameters and also defines selection of
data for selection-type parameters.

6.4 Parameter Description
(1) Menu B: Easy Setup items
Those parameters with a high frequency of use have
been grouped together in Easy Setup. All basic
functions can be controlled using only the parameters
from this block. Parameters from Menu B share
identical names with those from other menus; however,
modification of one such parameter will result in the
other being automatically modified.

[B20: Flow Damping] Setting of the damping time
constant
→ This setting is linked with that of parameter C11.
The damping time constant should be modified to
suppress an output fluctuation or to change the response time. This time constant has an effect on analog
output and on the flow rate display (i.e., actual instantaneous flow rate, %, current value), and in addition, it
also affects pulse output and totalization. However,
when “No Damping” has been set for J24: T/P Damp
Select, there will be no effect on pulse output or
totalization.
*Time constant: The time required for the output to
reach 63.2% from 0%.
[B21: Base Flow Unit] Selection of flow units for the
flow rate span
→ This setting is linked with that of parameter C40.
This parameter selects the flow units for the flow rate
span. (In case of mass flow, the setting of density is
also required. Refer to C46: Mass Flow Density
for more details.)

[B22: Base Time Unit] Selection of time units for
the flow rate span
→ This setting is linked with that of parameter C41.
This parameter selects the time units for the flow rate
span; however, if “m” or “ft” has been selected for the
flow rate units, “/s” is automatically set for this
parameter.
[B23: Flow Span] Setting of the flow rate span
→ This setting is linked with that of parameter C42.
The span can be set for the forward flow rate in the
range 0 to 32,000 (although this does not include 0). The
units set using B21/C40: Base Flow Unit and B22/
C41: Base Time Unit will be displayed at this time.
NOTE
If the flow rate units, time units, and flow rate
span are specified upon ordering, these parameters will be setup before shipment; however, if
this is not the case, it will be necessary for the
appropriate values to be set up by the user.
NOTE
Flow rate span is the value for instantaneous
flow rate that corresponds to a current output of
20 mA. The following factors should be taken
into consideration when deciding on the flow rate
span.
• In the case of applications with large variations
in flow rate, the maximum flow rate should be
set. If a flow rate in excess of the flow rate
span was to occur, output would be possible
up to an upper limit of 108%, and beyond this,
error would occur. Note that the same applies
to pulse output and totalization.
• In the case of applications that have a relatively stable flow rate, a flow rate span of 1.5 to
2.0 times larger than the normal flow rate may
be considered suitable.
• The flow rate to be adopted should - upon
conversion to flow velocity - correspond to a
value within the range of 0.1 to 10 m/s. (0.3 to
10 m/s for size 1100 mm or larger) The flow
velocity can be confirmed using sizing data or
with parameter C44: Velocity Check, and in
the latter case, the value obtained when span is
converted to flow velocity will be displayed.
• Regardless of the position of the decimal point,
the largest value that can be set on the display
unit is 32,000. Furthermore, it is not possible to
set a number of 4 or greater for the highestorder digit. Similarly, if 3 is set for this highestorder digit, it will not be possible to set a

number of 2 or greater for the next digit to the
right, regardless of the position of the decimal
point.
Example: A value of 333.33 is represented by
the character string 33333, and since
this exceeds 32000, it cannot be set.
In such a case, the value 333.3
should be set instead.
[B24: Flow Decimal Pnt] Setting of the decimal
point position for the instantaneous flow rate
→ This setting is linked with that of parameter C43.
This parameter sets the position of the decimal point
for instantaneous flow rate values in terms of the
number of digits. When set using “Auto”, the decimal
point position will be automatically determined in
accordance with the setting value for B23/C42: Flow
Span as shown below.
Flow Span 9Decimal point position: 3 digits
9 < Flow Span 90 Decimal point position: 2 digits
90 < Flow Span 900 Decimal point position: 1 digit

[B31: Total Scale] Setting of the totalization scale
→ This setting is linked with that of parameter D11.
The flow rate is totalized in individual counts in
accordance with this parameter’s setting. If 0 is
selected, it indicates that the totalization function is not
to be used.
NOTE
If a totalization scale is specified upon ordering,
this parameter is set up before shipment; however, if this is not the case, it will be necessary
for the appropriate value to be set up by the
user.
When an item other than “Auto” is set, the selected
number of digits for the decimal point position is used.
With the decimal point removed, 6 digits are available
for the instantaneous flow rate value, and display is
possible up to 999,999. If an overflow occurs as a
result of the setting adopted for decimal point position,
the warning 84: Disp Over Wng will be displayed to
provide notification of this condition.

[B30: Total Unit] Setting of units for totalization
scale
→ This setting is linked with that of parameter D10.
This parameter selects the flow rate units for use in
totalization.
NOTE
• By setting the totalization scale, the totalized
value is displayed on the display unit. The
totalization scale is determined in accordance
with the settings of B30/D10: Total Unit and
B31/D11: Total Scale.
• The maximum value that can be displayed is
99999999, and if this is exceeded, the value 0
is counted once again. However, counting
stops at 99999999 when the totalization switch
function is used.
• If multiple ranges are being used, the flow rate
span for the smallest range becomes the
standard for the D13: Total Low Cut setting
value.
• Totalization for the reverse flow rate and for the
differential flow rate is carried out only when
“Fwd/Rev Ranges” is selected for F10: SO1
Function or F11: SO2 Function.
• The totalized units are indicated on the display
unit when B31/D11 is 0.001, 0.01, 0.1, 1, 10,
100, or 1000. In the case of other setting
values, the totalized units are not indicated.

Status output is carried out when the forward internal
totalized value reaches or exceeds the totalization switch value.
The totalization switch value is determined using D23: Ttl
Switch Lower and D24: Ttl Switch Upper.
Status output is carried out when the instantaneous flow rate
equals or falls below the low flow rate limit (L), or when it equals
or exceeds the high flow rate limit (H). These limit values are
determined using G10: Low Alarm and G11: High Alarm.
Status output is carried out when the instantaneous flow rate
equals or falls below the low-low flow rate limit (LL), or when it
equals or exceeds the high-high flow rate limit (HH). These limit
values are determined using G12: Low Low Alarm and G13:
High-High Alarm. To output “HH/LL Alarm” as an alarm, set
G33: Alm-HH/LL to “Yes”.
When flow is in the reverse direction, switching to the reverse
range is carried out automatically, measurement is performed,
and status output is carried out.
This function ensures that when the

This parameter is used to force current output to
0%(i.e., 4mA) in the vicinity of 0% and setting for the
current (4 to 20mA) output low cut is made using a
percentage of the smallest flow rate span. However, the
low cut function will be terminated if this parameter is
set to 0%.

[J20: Flow Direction] Setting of the flow direction
Upon shipment from the manufacturing plant, the
system is setup such that flow in the same direction, as
shown by the direction of the arrow mark on the
flowtube, will be measured as forward flow; however,
this parameter can be used to set “Reverse” so that
flow in the opposite direction to the arrow mark will be
treated as forward.
Note: This function does not apply to measurement in
both the forward and reverse directions, although this can be setup using by selecting
“Fwd/Rev Ranges” from either F10: SO1
Function or .

[J21: Rate Limit] Setting of the rate limit value
䊉 This parameter is used in situations where sudden
noise cannot be eliminated by increasing the
damping time constant.
䊉 In situations where step signals or sudden noise
signals caused by slurries or the like are entered, this
parameter is used to set the standard for determining
whether an input corresponds to a flow measurement
or noise. Specifically, this determination is made
using upper and lower rate limits and using the dead
time.
䊉 Rate limit values are set using a percentage of the
smallest range. The range of deviation per one
calculation cycle should be input.
䊉 Signal processing method:
A fixed upper and lower limit value is setup with
respect to the primary delay response value for the
flow rate value obtained during the previous sampling, and if the currently sampled flow rate is
outside these limits, then the corresponding limit is
adopted as the current flow rate value. In addition, if
signals which breach the limits in the same direction
occur over multiple samples (i.e., within the dead
time), it is concluded that the corresponding signal is
a flow rate signal.

(1) In comparison with the previous value at (a), it is
determined that the signal is in excess of the rate
limit value and the response becomes 1%. However, the actual output applies damping, and
therefore the output turns out to be as indicated by
the solid line.
%
[J22: Dead Time] Setting of dead time
This parameter sets the time for application of the rate
limit, and if a value of 0 is set, the rate limit function
will be terminated.
NOTE
Determining rate limit value and dead time
Rate limit value:
Determines the level for output
fluctuation cutoff. For example,
if this is set to 2%, noise above
2% will be eliminated as shown
in the diagram.

output fluctuation width. If noise

(2) Subsequent flow values within the dead time zone
correspond to signals of post-damping flow value
+ rate limit value (1%).
(3) Since input signals do not return to within the rate
limit value during the dead time, it is determined at
(c) that this signal is a flow rate signal.
(4) The output signal becomes a damped curve and
compliance with the step signal begins.
Three seconds after determination of a flow rate
signal in the above figure, a level of 63.2% is
reached.

8.1.1 Interconnectwion between AXFA11 and HART Communicator
The HART Communicator can interface with the AXFA11 from the control room, the
AXFA11 site, or any other wiring termination point in the loop, provided there is a minimum
load resistance of 230 between the connection and the receiving instrument. To communicate, it must be connected in parallel with the AXFA11, and the connections must be nonpolarized. Figure 8.1.1 illustrates the wiring connections for a direct interface at the AXFA11
site. The HART Communicator can be used for remote access from any terminal strip as well.

9. ACTUAL OPERATION
After you have installed the flowtube into the process
piping, wired the input/output terminals, set up the
required parameters, and performed a pre-operation
zero adjustment, the magnetic flowmeter should output
an accurate flow signal from its terminals as soon as
flow of the fluid to be measured begins. This section
describes zero adjustment and the corresponding
procedures.
9.1 Pre-operation Zero Adjustment
Zero adjustment is carried out to ensure that the output
for zero flow is 0% (i.e., 4 mA). Although adjustment
to zero is performed at the manufacturing plant prior to
shipment, this procedure must be carried out once
again following the installation of piping in order to
match the magnetic flowmeter to its operating conditions.
9. ACTUAL OPERATION
This section describes the zero adjustment procedure
using display unit switches from the converter and
using the external status input; accordingly, one of
these methods should be selected and implemented.
IMPORTANT
• Zero adjustment should be carried out before
actual operation. Note that setting and update
functions cannot be carried out during this
procedure (i.e., for approximately 30 seconds).
• Zero adjustment should only be carried out
when the flowtube has been filled with fluid and
the fluid velocity is completely zero by closing
the valve.
• Each time that the fluid being measured is
changed, it will be necessary for zero adjustment to be carried out for the new fluid.
9-1
IM 01E20C01-01E
9.1.1 Zero Adjustment Using Display Unit Switches
This section describes the procedure for zero adjustment using the display unit switches.
(For more details regarding setting methods using these switches, refer to Chapter 5: Basic
Operating Procedures.)
The parameters for zero adjustment are B50/M10: Auto Zero Exe (and either of these
can be used to carry out this procedure). For more details regarding these parameters, refer
to Chapter 6: Parameter Description.
The parameter M10: Auto Zero Exe will be used in the following description.
