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
four-core cables are used for wiring. Keep
conduits or flexible tubes watertight using
sealing tape.
• Ground the remote flowtube and the converter
separately.
• Cover each shield of the signal cable with vinyl
tube or vinyl tape to avoid contact between two
shields or between a shield and a case.
• When waterproof glands or union equipped
waterproof glands are used, avoid tightening
the glands with an excessive torque.
• In case of 24V power supply version, it comes
with a plug. Use this plug to cover the unused
wiring port when wiring the instrument with only
one, four-core cable.
• Be sure to turn power off before opening the
cover.
• Before turning the power on, tighten the cover
securely.
• The terminal box cover is locked by the special
screw. In case of opening the terminal box
cover, use the hexagonal wrench attached. For
handling the locking screw, refer to Figure
4.4.1.
• Be sure to lock the cover by the special screw
using the hexagonal wrench attached after
installing the cover. For handling the locking
screw, refer to Figure 4.4.12.
• Explosion protected types must be wired in
accordance with specific requirement (and, in
certain countries, legal regulations) in order to
preserve the effectiveness of their explosion
protected features.

CAUTION
• As crimp terminals A, B, SA, SB and C have
their own electrical potentials, securely insulate
them so as not to come in contact with one
another.
• To prevent a shield from coming in contact with
another shield or the case, cover each shield
with a vinyl tube or wrap it in vinyl tape.

4. WIRING
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.

WARNING
Before wiring with external instruments, be sure
to turn off the power supply for AXFA14
converter and any external instruments.
Pulse Output
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 DO+ and DO– 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.
Connect the AXFA14 terminal to external instruments,
giving attention to the following points.

NOTE
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 FOUNDATION 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 parameters. If you turn the power off immediately after
the parameters are set, the settings will be
canceled.
6.2 Parameter Lists
Parameter lists are comprised of the following items.
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 flowmeter is ordered, the nominal size and meter factor
will be set upon shipment from the manufacturing 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.

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.

display unit.

Spanish
[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” 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.
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.
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. 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 9 Decimal point position: 3 digits
9 < Flow Span 90 Decimal point position: 2 digits
90 < Flow Span 900 Decimal point position: 1 digit
900 < Flow Span Decimal point position: no
digits (i.e., no decimal point)

[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.
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.
• 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 F20: DO
Function or F21: DIO 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

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: AlmHH/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 instantaneous flow
rate exceeds 100% of the range, transition to the next
range is carried out automatically. Status output is carried
out upon range switching.
When range switching is carried out in response to external
status input, status output is performed in the form of an
answerback to indicate the range currently being used.
Based on the external status input, the instantaneous flow rate
indication is forcibly set to 0% (i.e., 4 mA), and both totalization
and pulse outputs are halted. This setting has precedence over the
output signal whenever an alarm occurs. When the 0% signal lock is
canceled, the instantaneous flow rate is restored in accordance with
the time constant originally set using B20/C11: Flow Damping.
Automatic zero adjustment is carried out in response to
external status input. For more details regarding automatic
zero adjustment, refer to Chapter 9: Operation.
The totalization display value is preset or reset to zero in
accordance with the external status input. The preset value is
determined using D21: Ttl Set Val Lower and D22: Ttl Set
Val Upper.
In case that “Start” is selected for D20: Total Execution, the
count for totalization starts from the preset value.
This function allows the switching of 2 ranges in response
to status input for a single direction only.

NOTE
Multiple ranges setting
Parameters from F30 to F41 are used with the
automatic multiple ranges and the multiple
ranges switching via an external status input.
The followings will describe the setting method
for each range.
The multiple ranges use the following parameters:
[B23: Flow Span] Setting of the flow rate span
(Setting of the forward No.1 range)
[F30: Forward Span 2] Setting of the forward No.2
range
[F31: Forward Span 3] Setting of the forward No.3
range
[F32: Forward Span 4] Setting of the forward No.4
range
[F33: Reverse Span 1] Setting of the reverse No.1
range
[F34: Reverse Span 2] Setting of the reverse No.2
range
[F40: Auto Range Hys] Setting of the automatic
multiple ranges hysteresis width.
[F41: Bi Direction Hys] Setting of the forward/
reverse flow measurement hysteresis width
Multiple Ranges Setting 1:

When the instantaneous flow rate exceeds 100% of
the range, transition to the next range (up to four
ranges) is carried out automatically. Furthermore,
when the flow is in reverse, the reverse range is
automatically selected.
Range switching can be confirmed according to the
status of the DO and DIO status output terminals.
Refer to Table 6.4.1: Status Output for Automatic
Multiple Ranges Switching for details of status
output conditions for each range.

[J21: Rate Limit] Setting of the rate limit value
This parameter is used in situations where sudden
noise cannot be eliminated by increasing the
damping time constant.
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.
Rate limit values are set using a percentage of the
smallest range. The range of deviation per one
calculation cycle should be input.
[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.

If “21.6mA or more” has been set for G21:4-20
mA Alarm Out, 21.6mA or more will be output
upon an alarm occurrence, regardless of the
high limit setting.
[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.

Determining rate limit value and dead time
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.
(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.
[J24: T/P Damp Select] Setting of damping operation

The nominal size unit, nominal size and meter
factor have been properly set upon shipment
from the manufacturing plant. Do not change
these parameters.

[C22: High MF] Setting of the high-frequency meter
factor
[C23: Low MF (EDF)] Setting of the low-frequency
meter factor for enhanced DF (i.e., enhanced dual
frequency excitation)

(1) Confirm that the meter factors indicated on
your AXF integral flowmeter’s data plate has
been set to the parameters.
(2) The meter factors are crucial in ensuring that
the electromotive force is correctly in proportion to the flow velocity and are determined
at the manufacturing plant by actual-flow
calibration.
For the hardware configuration of the AXF
integral flowmeter, see the user’s manual of the
AXF Integral Flowmeter [Hardware Edition] (IM

WARNING
Be sure to set parameters as “Protect” on the
write protect function after finish of parameter
setting work.
Under extremely rare case, the infra-red
switches may respond unexpectedly in such
conditions as sticking ball of water or extraneous
substances on the surface of display panel glass
according to the principle of infra-red switch
operation.
Its probability rises in such cases as sticking rain
water by storm or other similar situation and
washing up work near flowmeter installation
place.
Either to illuminate or stop illuminating the infrared switches by the flashlight may cause the
mis-reaction.
In case of BT200, the parameters are displayed
in English only.
Even if the language with the exception of English
is selected at B10/H30: Language, the parameters are displayed in English upon BT200.

WARNING
Be sure to set parameters as “Protect” on the
write protect function after finish of parameter
setting work.
Under extremely rare case, the infra-red
switches may respond unexpectedly in such
conditions as sticking ball of water or extraneous
substances on the surface of display panel glass
according to the principle of infra-red switch
operation.
Its probability rises in such cases as sticking rain
water by storm or other similar situation and
washing up work near flowmeter installation
place.
Either to illuminate or stop illuminating the infrared switches by the flashlight may cause the
mis-reaction.
Refer to Chapter 6 “Menu P: Parameter Protection Items” and section “10.2.2” how to use the
write protect function in detail. This menu in the
275 is located at [Hot key] → [2 Wrt Protect

8. OPERATION VIA HART COMMUNICATOR
8.4.3 Self-diagnostic
The self-diagnostic function of the AXFA14 is explained in Section 6.5 “Alarm Functions.”
The HART configuration tool can be used to run
self-diagnostics on a device and check for incorrect
data settings.
(1) Using DD
The Self test and Status commands are available for
self-diagnostics. When Self test is run, the display unit
shows an error code and alarm message if the device
detects any illegal parameter settings or functional
faults.
• Procedure to call up the Self test display
Device Setup → Diag/Service → Test → Self test
If no error is detected, “Self test OK” is displayed on
the configuration tool.
If the specific diagnostic item is known for the check,
you can directly call up the item by using the Status
command.
The status is categorized from 1 to 7.
Show an example below to confirm the status of Status
group 1.
• Procedure to call up the Status display
Device Setup → Diag/Service → Status → Status group 1
If no error is detected, “Off” is displayed on the
configuration tool.
If there is an error, “On” is displayed on the configuration tool, and a countermeasure for that error is
necessary.
Example of display: Span > 10 m/s On
Span < 0.3 m/s Off
TTL > 10000 p/s Off
TTL < 0.0001 p/s Off
4-20 Lmt Err Off
The HART configuration tool diagnoses at each
communication.
When an improper operation is performed, the error
message is displayed.
(2) Using DTM
The Device Status commands are used for
self-diagnostics. When Device Status is run, the
display unit shows an error code and alarm message if
the AXFA14 detects any illegal parameter settings or
functional faults.
If no error is detected, “Status: Normal” is displayed
on the configuration tool.
If the specific diagnostic item is known for the check,
you can directly call up the item by using the Diagnostic List in the Device Status display.
The Diagnostic List is categorized to Device Status,
Hardware Failure, Transducer Status, Diag Status, and
Configuration.
If no error is detected, color symbol which shows
Normal State is displayed on top of the error message.
If color symbol which shows Error State is displayed,
there is an error and a countermeasure for that error is
necessary.
The HART configuration tool diagnoses at each
communication.
When an improper operation is performed, the error
message is displayed.
8.4.4 HART Specific Functions
Trim Analog Output
This function is used to adjust the analog output at
4 mA and 20 mA with the D/A trim or Scaled D/A trim.
(1) D/A trim
Connect a calibration digital ammeter, and then
enter the read value of the ammeter for each output
of AXFA14.
• Procedure to call up the D/A trim display
DD Device Setup → Diagnosis/Service →
Adjustment → D/A trim
DTM Calibration → D/A trim
T0808.EPS
(2) Scaled D/A trim
The output is adjusted by using a voltmeter or
other types of meters with 0 to 100% scale.
Example using a voltmeter:
4 mA DC → 1 V
20 mA DC → 5 V
Connect this meter, and enter the read value of the
meter for each output of AXFA14.
• Procedure to call up the Scaled D/A trim

8. OPERATION VIA HART COMMUNICATOR
IMPORTANT
The D/A trim should be executed only at single
range mode. If the D/A trim is executed at Bi
direction mode, it is possible that the current
output becomes 108%.
IMPORTANT
When “D/A trim” or “Scaled D/A trim” is carried
out, the warning message “83: Fix Cur Wng” is
displayed on the display unit.
CAUTION
The output adjustment function can match the
4mA and 20mA output to the reference meter
such as a voltmeter. In the output adjustment, it
is necessary to use the calibrated voltmeter and
resistance.
Fixed Current Output
This feature can be used to output a fixed current for
loop checks.
In the case of using DD
Call up the test output parameter (Loop test) and select
the output signal.
• Procedure to call up the display
DD Device Setup → Diagnosis/Service →
Test → Loop test →
→ 4mA Output a 4mA DC signal
→ 20mA Output a 20mA DC signal
→ Other Set a desired output signal value
→ End Exit
T0806.EPS
In the case of using DTM
Call up the test output parameter (Loop test) and select
either manual test or auto test, and set the current
value.
• Procedure to call up the display
DTM Diag and Service → Output Test →
Loop test →
→ Manual Test Set the current value or % value at
Test output value, then click the Start
button.
→ Auto Test Set the interval and rate of change of
current output at Auto Test Setting,
then click the Start button.
T0807.EPS
Burst Mode
AXFA14 continuously sends the data via HART
communication when the burst mode is set on (any one
of PV, % range/current, or process vars/crnt). The data
is sent intermittently as a digital signal at 3 times a
second.
The burst mode is set as follows.
(1) Setting the data to be sent
• Procedure to call up the display
DD Device Setup → Detailed setup
→ HART output → Burst option
DTM Confi guration → HART → Burst option
T0810.EPS
Select the type of data to be sent from the following
options:
- Instantaneous flow rate (PV)
- Output in % and current output (% range/current)
- Instantaneous flow rate, totalization value* and
current output (Process vars/crnt)
* “Totl,” “Reverse Totl” or “Dif Totl”
(2) Setting the burst mode
• Procedure to call up the display
DD Device Setup → Detailed setup →
HART output → Burst mode
DTM Confi guration → HART → Burst mode
T0811.EPS
Then, select “On” at the menu to start the burst
mode.
To release from the burst mode, call up the burst
mode display, and set to “Off.”
The default setting is “Off.”
Multidrop Mode
When set in the multidrop mode, up to 15 field devices
in a single communications line can be connected. To
activate multidrop communication, the address of the
field devices must be set to a number from 1 to 15.
This deactivates the 4 to 20 mA analog output, fixing it
to 4 mA. Burn out is also disabled.
Note that the accuracy for multidrop mode is different
from that for other modes. Refer to Chapter 11:
Outline.
The multidrop mode is set as follows.
(1) Setting the polling address
• Procedure to call up the display
DD (HART 5) Device Setup → Detailed setup →
Output condition → HART output →
DTM (HART 5) Confi guration → HART →
→ Poll addr Enter the number from 1 to 15
T0812.EPS

IM 01E20C02-01E
(2) Activating the multidrop mode
About the procedure to call up the Polling display,
please refer to the User’s Manual of each configuration tool.
NOTE
When the same polling address is assigned for
two or more field devices in multidrop mode,
communication with these field devices is
disabled.
(3) Communication when set in the multidrop mode
1. The HART configuration tool searches a field
device that is set in the multidrop mode when
the HART configuration tool is turned on.
When the HART configuration tool is connected
to the field device, the polling address and the
tag will be displayed.
2. Select the field device, and then communication
with it is possible. The communication speed is
slow in this case.
3. To communicate with another field device, turn
off the power once and then turn it back on, or

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.
For F
OUNDATION Fieldbus protocol, please refer to IM
01E20F02-01E.
For PROFIBUS PA protocol, please refer to IM
01E20F12-01E.
9.1 Pre-operation Zero
9. ACTUAL OPERATION
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.
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
measurement 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.

IM 01E20C02-01E
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.

•Removing and installing cover are necessary
for setting switches. Perform removing and
installing of the cover as described in section
10.1.2.1 and 10.1.2.3.
• To preserve the safety, do not touch the
electrical circuit and the cables except the
setting switches.
10.2.1 Setting of Burnout Switch
The burnout function sets the direction of current
output in situations where the CPU has become
damaged. Upon shipment from the manufacturing
plant, the burnout direction is set to High (i.e., 25 mA);
however, in cases where the optional code C1 has been
specified, the output direction will be set to Low
(i.e., 0 mA).
Modification of the burnout direction must be carried
out using the setting switch from the amplifier’s CPU
board (i.e., Switch 1) (See Figure 10.2.1).

10.2.2 Setting of Write Protect Switch
By setting the write protect function to “Protect” it is
possible to prevent the overwriting of parameters.
Write protection can be carried out using either the
hardware switch on the CPU board (i.e., Switch 2) or
software parameter settings. If either of these items is
set to “Protect,” the overwriting of parameters will be
prohibited.

• On the amplifier’s CPU board, the burnout
setting switch (i.e., Switch 1) and the write
protect switch (i.e., Switch 2) are located
adjacent to each other. Accordingly, special
care should be taken when making switch
settings.
• In the case of Fieldbus communication type,
burnout setting swich is not applied.

• If the hardware switch is set to “Protect,” it will
not be possible to overwrite parameters;
furthermore, this condition will be maintained
until the switch is set to “Enable.”
• In the case of Fieldbus communication type,
write protect setting switch is always be set as
“Enable”.
For more details regarding usage of the write protect
function and the software’s parameter switches, refer to
“Chapter 6: Parameter Description” in this user’s
manual.
