HANDLING CAUTIONS
This chapter describes important cautions regarding
how to handle the transmitter. Read carefully before
using the transmitter.
The EJA-A Series pressure transmitters are thoroughly
tested at the factory before shipment. When the
transmitter is delivered, visually check them to make
sure that no damage occurred during shipment.
Also check that all transmitter mounting hardware
shown in Figure 2.1 is included. If the transmitter was
ordered without the mounting bracket or without the
process connector, the transmitter mounting hardware
is not included. After checking the transmitter, repack
it in the way it was delivered until installation.

2.1 Model and Specifications
Check
The model name and specifications are indicated on the
name plate attached to the case. If the reverse operating mode was ordered (reverse signal), ‘REVERSE’
will be inscribed in field *1.
(b) When storing the transmitter, repack it as nearly
as possible to the way it was packed when
delivered from the factory.
(c) If storing a transmitter that has been used,
thoroughly clean the chambers inside the cover
flanges, so that no measured fluid remains in it.
Also make sure before storing that the pressuredetector and transmitter section are securely
mounted.
2.4 Selecting the Installation
Location
The transmitter is designed to withstand severe
environmental conditions. However, to ensure stable
and accurate operation for years, observe the following precautions when selecting an installation location.
2-1
IM 01C21D01-01E
2. HANDLING CAUTIONS
(a) Ambient Temperature
Avoid locations subject to wide temperature
variations or a significant temperature gradient. If
the location is exposed to radiant heat from plant
equipments, provide adequate thermal insulation
and/or ventilation.
(b) Ambient Atmosphere
Avoid installing the transmitter in a corrosive
atmosphere. If the transmitter must be installed in a
corrosive atmosphere, there must be adequate
ventilation as well as measures to prevent intrusion
or stagnation of rain water in conduits.
(c) Shock and Vibration
Select an installation site suffering minimum shock
and vibration (although the transmitter is designed
to be relatively resistant to shock and vibration).
(d) Installation of Explosion-protected Transmitters
Explosion-protected transmitters can be installed in
hazardous areas according to the types of gases for
which they are certified. See Subsection 2.9
“Installation of Explosion Protected Type Transmitters.”
2.5 Pressure Connection
WARNING
• Instrument installed in the process is under
pressure. Never loosen the process connector
bolts to avoid the dangerous spouting of
process fluid.
• During draining condensate from the pressuredetector section, take appropriate care to avoid
contact with the skin, eyes or body, or inhalation of vapors, if the accumulated process fluid
may be toxic or otherwise harmful.
The following precautions must be observed in order to
safely operate the transmitter under pressure.
(a) Make sure that the two process connector bolts are
tightened firmly.
(b) Make sure that there are no leaks in the impulse
piping.
(c) Never apply a pressure higher than the specified
maximum working pressure.
2.6 Waterproofing of Cable
Conduit Connections
Apply a non-hardening sealant to the threads to
waterproof the transmitter cable conduit connections.
(See Figure 6.4.2a, 6.4.2b and 6.4.2c.)
2.7 Restrictions on Use of Radio
Transceiver
IMPORTANT
Although the transmitter has been designed to
resist high frequency electrical noise, if a radio
transceiver is used near the transmitter or its
external wiring, the transmitter may be affected
by high frequency noise pickup. To test for such
effects, bring the transceiver in use slowly from a
distance of several meters from the transmitter,
and observe the measurement loop for noise
effects. Thereafter, always use the transceiver
outside the area affected by noise.
2.8 Insulation Resistance and
Dielectric Strength Test
Since the transmitter has undergone insulation resistance and dielectric strength tests at the factory before
shipment, normally these tests are not required.
However, if required, observe the following precautions in the test procedures.
(a) Do not perform such tests more frequently than is
absolutely necessary. Even test voltages that do not
cause visible damage to the insulation may degrade
the insulation and reduce safety margins.
(b) Never apply a voltage exceeding 500 V DC (100 V
DC with an internal lightning protector) for the
insulation resistance test, nor a voltage exceeding
500 V AC (100 V AC with an internal lightning
protector) for the dielectric strength test.
(c) Before conducting these tests, disconnect all signal
lines from the transmitter terminals. Perform the
tests in the following procedure:
• Insulation Resistance Test
1) Short-circuit the + and – SUPPLY terminals in the
terminal box.
2) Turn OFF the insulation tester. Then connect the
insulation tester plus (+) lead wire to the shorted
SUPPLY terminals and the minus (–) leadwire to
the grounding terminal.
3) Turn ON the insulation tester power and measure
the insulation resistance. The voltage should be
applied short as possible to verify that the insulation resistance is at least 20 MΩ.
4) After completing the test and being very careful not
to touch exposed conductors disconnect the
insulation tester and connect a 100 kΩ resistor
between the grounding terminal and the short2-2
IM 01C21D01-01E
2. HANDLING CAUTIONS
circuiting SUPPLY terminals. Leave this resistor
connected at least one second to discharge any
static potential. Do not touch the terminals while it
is discharging.
• Dielectric Strength Test
1) Short-circuit the + and – SUPPLY terminals in the
terminal box.
2) Turn OFF the dielectric strength tester. Then
connect the tester between the shorted SUPPLY
terminals and the grounding terminal. Be sure to
connect the grounding lead of the dielectric strength
tester to the ground terminal.
3) Set the current limit on the dielectric strength tester
to 10 mA, then turn ON the power and gradually
increase the test voltage from ‘0’ to the specified
voltage.
4) When the specified voltage is reached, hold it for
one minute.
5) After completing this test, slowly decrease the
voltage to avoid any voltage surges.

INSTALLING IMPULSE PIPING
5.1 Impulse Piping Installation
Precautions
5.1.2 Routing the Impulse Piping
(1) Process Pressure Tap Angles
If condensate, gas, sediment or other extraneous
material in the process piping gets into the impulse
piping, pressure measurement errors may result. To
prevent such problems, the process pressure taps must
be angled as shown in Figure 5.1.2 according to the
kind of fluid being measured.
The impulse piping that connects the process outputs to
the transmitter must convey the process pressure
accurately. If, for example, gas collects in a liquidfilled impulse piping, or the drain of a gas-filled
impulse piping becomes plugged, the impulse piping
will not convey the pressure accurately. Since this will
cause errors in the measurement output, select the
proper piping method for the process fluid (gas, liquid,
or steam). Pay careful attention to the following points
when routing the impulse piping and connecting the
impulse piping to the transmitter.
NOTE
• If the process fluid is a gas, the taps must be
vertical or within 45° either side of vertical.
• If the process fluid is a liquid, the taps must be
horizontal or below horizontal, but not more
than 45° below horizontal.
• If the process fluid is steam or other condensing vapor, the taps must be horizontal or above
horizontal, but not more than 45° above horizontal.

Piping)
(2) Tightening the Process Connector Mounting Bolts
After connecting the impulse piping, tighten the
process connector mounting bolts uniformly.
(2) Position of Process Pressure Taps and
Transmitter
If condensate (or gas) accumulates in the impulse
piping, it should be removed periodically by opening
the drain (or vent) plugs. However, this will generate a
transient disturbance in the pressure measurement, and
therefore it is necessary to position the taps and route
the impulse piping so that any extraneous liquid or gas
generated in the leadlines returns naturally to the
process piping.
• If the process fluid is a gas, then as a rule the
transmitter must be located higher than the process
pressure taps.
• If the process fluid is a liquid or steam, then as a
rule the transmitter must be located lower than the
process pressure taps.
5-1
IM 01C21D01-01E
5. INSTALLING IMPULSE PIPING
(3) Impulse Piping Slope
The impulse piping must be routed with only an
upward or downward slope. Even for horizontal
routing, the impulse piping should have a slope of at
least 1/10 to prevent condensate (or gases) from
accumulating in the pipes.
5.2 Impulse Piping Connection
Examples
Figure 5.2 shows examples of typical impulse piping
connections. Before connecting the transmitter to the
process, study the transmitter installation location, the
process piping layout, and the characteristics of the
process fluid (corrosiveness, toxicity, flammability,
etc.), in order to make appropriate changes and
additions to the connection configurations.
(4) Preventing Freezing
If there is any risk that the process fluid in the impulse
piping or transmitter could freeze, use a steam jacket or
heater to maintain the temperature of the fluid.
Note the following points when referring to these
piping examples.
• The transmitter impulse piping connection is shown
for a vertical impulse piping connection configuration in which the direction of connection is either
upwards or downwards.
• If the impulse piping is long, bracing or supports
should be provided to prevent vibration.
• The impulse piping material used must be compatible with the process pressure, temperature, and
other conditions.
• A variety of process pressure tap valves (main
valves) are available according to the type of
connection (flanged, screwed, welded), construction
(globe, gate, or ball valve), temperature and
pressure. Select the type of valve most appropriate
for the application.
NOTE
After completing the connections, close the valves
on the process pressure taps (main valves), the
valves at the transmitter (stop valves), and the
impulse piping drain valves, so that condensate,
sediment, dust and other extraneous material
cannot enter the impulse piping.

6.1 Wiring Precautions
IMPORTANT
• Lay wiring as far as possible from electrical
noise sources such as large capacity transformers, motors, and power supplies.
• Remove electrical connection dust cap before
wiring.
• All threaded parts must be treated with waterproofing sealant. (A non-hardening silicone
group sealant is recommended.)
• To prevent noise pickup, do not pass signal
and power cables through the same ducts.
• Explosion-protected instruments must be wired
in accordance with specific requirements (and,
in certain countries, legal regulations) in order
to preserve the effectiveness of their explosionprotected features.
• The terminal box cover is locked by an Allen
head bolt (a shrouding bolt) on CENELEC and
IECEx flameproof type transmitters. When the
shrouding bolt is driven clockwise by an Allen
wrench, it is going in and cover lock is released, and then the cover can be opened by
hand. See Subsection 9.4 “Disassembly and

7.3 Starting Operation
7.5 Venting or Draining Transmitter Pressure-detector Section
After completing the zero point adjustment, follow the
procedure below to start operation.
Since this transmitter is designed to be self-draining
and self-venting with vertical impulse piping connections, neither draining nor venting will be required if
the impulse piping is configured appropriately for selfdraining or self-venting operation.
1) Confirm the operating status. If the output signal
exhibits wide fluctuations (hunting) due to periodic
variation in the process pressure, use BT200 to
dampen the transmitter output signal. Confirm the
hunting using a receiving instrument or the integral
indicator, and set the optimum damping time
constant. See Subsection 8.3.3 (3), “Damping Time
Constant Setup.”
2) After confirming the operating status, perform the
following.
If condensate (or gas) collects in the transmitter
pressure-detector section, the measured pressure may
be in error. If it is not possible to configure the piping
for self-draining (or self-venting) operation, you will
need to loosen the drain (vent) screw on the transmitter
to completely drain (vent) any stagnated liquid (gas).
However, since draining condensate or bleeding off gas
gives the pressure measurement disturbance, this
should not be done when the loop is in operation.
IMPORTANT
• Remove the BT200 from the terminal box, and
confirm that none of the terminal screws are
loosened.
• Close the terminal box cover and the amplifier
cover. Screw each cover in tightly until it will
not turn further.
• Two covers are required to be locked on the
CENELEC and IECEx Flameproof type transmitters. An Allen head bolts (shrouding bolts)
are provided under edge of the each cover for
locking. When a shrouding bolts are driven
counterclockwise by an Allen wrench, it is
coming out and locks up a cover. (See page 93) After locking, the covers should be confirmed not to be opened by hand.
• Tighten the zero-adjustment cover mounting
screw to fix the cover in position.
WARNING
Since the accumulated liquid (or gas) may be
toxic or otherwise harmful, take appropriate care
to avoid contact with the body, or inhalation of
vapors.
7.5.1 Draining Condensate
1) Gradually open the drain screw or drain plug and
drain the transmitter pressure-detector section. (See
Figure 7.5.1.)
2) When all accumulated liquid is completely removed, close the drain screw or drain plug.
3) Tighten the drain screw to a torque of 10 N·m, and
the drain plug to a torque of 34 to 39 N·m.
7.4 Shutting Down Operation
Shut down the transmitter operation as follows.
1) Turn off the power.
2) Close the stop valve.
3) Close the tap valve.
NOTE
Drain plug
Whenever shutting down the transmitter for a
long period, remove any process fluid from the
transmitter pressure-detector section.

has stabilized before proceeding to the next step.
Note 2: If the pressure applied to the transmitter exceeds the previous
LRV (or HRV), the integral indicator may display error
number “Er.07” (In this case, the output signal percent and
“Er.07” are displayed alternately every two seconds).
Although “Er.07” is displayed, you may proceed to the next
step. However, should any other error number be displayed,
take the appropriate measure in reference to Subsection
8.5.2, “Errors and Countermeasures.”

IMPORTANT
7.6 Setting the Range Using the
Range-setting Switch
• Do not turn off the power to the transmitter
immediately after completion of the change in
the LRV and/or HRV setting(s). Note that
powering off within thirty seconds after setting
will cause a return to the previous settings.
• Changing LRV automatically changes HRV to
the following value.
With actual pressure being applied to the transmitter,
the range-setting switch (push-button) located on the
optional integral indicator plate and the external zeroadjustment screw allow users to change (re-range) the
low- and high-limit values for the measurement range
(LRV and HRV) without using BT200. However, other
changes in the display settings (scale range and
engineering unit) for the integral indicator requires
BT200.
HRV = previous HRV + (new LRV – previous LRV)
• If the range-setting push-button and external
zero-adjustment screw are not touched during a
range-change operation, the transmitter automatically switches back to the normal operation
mode.
Follow the procedure below to change the LRV and
HRV settings.
[Example]
Integral indicator
Rerange LRV to 0 and HRV to 3 MPa.
1) Connect the transmitter and apparatus as shown in
Figure 9.3.1 and warm up for at least five minutes.
2) Press the range-setting push-button.
The integral indicator then displays “LSET.”
3) Apply a pressure of 0 kPa (atmospheric pressure) to
the transmitter. (Note 1)
4) Turn the external zero-adjustment screw in the
desired direction. The integral indicator displays the
output signal in %. (Note 2)
5) Adjust the output signal to 0% (1 V DC) by rotating
the external zero-adjustment screw. Doing so
completes the LRV setting.
Note : Use a thin bar which
has a blunt tip, e.g.,
a hexagonal wrench,
to press the rangesetting push-button

Before describing the procedure for setting parameters, we present the following table showing how
the parameters are used and in what case.
If the transmitter is turned off within 30 seconds
after parameters have been set, the set data
will not be stored and the terminal returns to
previous settings.

Calibration range setup
P.8-7
Description
Sets the Tag No. (using 16 alphanumeric characters).
Note: Up to 8 alphanumerics (upper case letters) can be used in the BT100.
Sets the calibration range for 4 to 20 mA DC. Sets three data items: range unit, input value
at 4 mA DC (LRV), and input value at 20 mA DC (HRV).
Note: LRV and HRV can be specified with range value specifications up to 5 digits
(excluding any decimal point) within the range of –32000 to 32000.

P.8-8
Output signal low cut mode setup
P.8-9
Adjusts the output response speed for 4 to 20 mA DC.
Can be set in 9 increments from 0.2 to 64 s.
Used mainly to stabilize output near 0% if output signal is the square root mode.
Two modes are available: forcing output to 0% for input below a specific value, or changing
to proportional output for input below a specific value.
Change the output limits
P.8-9
Integral indicator scale range and
unit setup
P.8-9
Change the range of normal output.
Sets the following 5 types of integral indicator scale ranges and units:
% scale indicator, user set scale indicator, alternate indication of user set scale
and % scale, input pressure display, alternate indication of input pressure and % scale
When using the user set scale, 4 types of data can be set:
user set scale setting, unit (BT200 only), display value at 4 mA DC (LRV), and display
value at 20 mA DC (HRV).
Note: LRV and HRV can be specified with range value specifications up to 5
digits (excluding any decimal point) within the range of –19999 to 19999.
Unit setup for displayed temperature
P.8-11
Sets a unit for temperatures displayed on the BT200.
Operation mode (normal/reverse
signal) setup
P.8-11
Reverses the direction for 4 to 20 mA DC output relative to input.
Reverse mode is used for applications in which safety requires that output be
driven toward 20 mA if input is lost.
Output status display/setup when
a CPU failure P.8-11
Displays the status of 4 to 20 mA DC output when a CPU failure. The parameter
of the standard unit is fixed to the high limit value.
Output status setup when a hardware Sets the status of the 4 to 20 mA DC output when an abnormal status is detected
error occurs
with the capsule or the amplifier as the result of self-diagnosis. One of the
P.8-11
following statuses; last held, high limit, and low limit values, can be selected.
Range change (while applying
actual inputs)
P.8-12
Range for 4 to 20 mA DC signal is set with actual input applied. Sets 20 mA DC output
precisely with respect to user’s reference instrument output. Note that DPharp is calibrated
with high accuracy before shipment, so span should be set using the normal range setup.
Zero point adjustment
P.8-12
Adjusts zero point. This can be done either using the external zero-adjustment screw on
the transmitteror using the BT200.
Span adjustment
P.8-14
Adjust the characterization curve. All the transmitters are calibrated at factory and this
adjustment is normally not necessary for most cases. Use for specific purposes.
Test output (fixed current output)

Turn the zero-adjustment screw on the outside of the
transmitter case using a slotted screwdriver. Turn the
screw to the right to increase the zero point or to the
left to decrease the zero output; the zero adjusts in
increments of 0.01% of the range setting.
Note that the amount of adjustment to the zero point
changes according to the speed at which the screw is
turned. To make fine adjustments, turn the screw
slowly; to make coarse adjustments, turn the screw
quickly.
Suppose that a standard pressure of 30 kPa is applied and

MAINTENANCE
9.1 Overview
WARNING
Since the accumulated process fluid may be
toxic or otherwise harmful, take appropriate care
to avoid contact with the body, or inhalation of
vapors during draining condensate or venting
gas in transmitter pressure-detector section and
even after dismounting the instrument from the
process line for maintenance.
Maintenance of the transmitter is easy due to its
modular construction. This chapter describes the
procedures for calibration, adjustment, and the disassembly and reassembly procedures required for
component replacement.
9.2 Calibration Instruments Selection
Table 9.2.1 shows the instruments required for calibration. Select instruments that will enable the transmitter
to be calibrated or adjusted to the required accuracy.
The calibration instruments should be handled carefully
so as to maintain the specified accuracy.
9.3 Calibration
Use the procedure below to check instrument operation
and accuracy during periodic maintenance or troubleshooting.
1) Connect the instruments as shown in Figure 9.3.1
and warm up the instruments for at least five
minutes.
Since the transmitters are precision instruments,
carefully and thoroughly read the following sections
for proper handling during maintenance.
IMPORTANT
• To adjust the transmitter for highest accuracy,
make adjustments with the power supply
voltage and load resistance including leadwire
resistances set close to the conditions under
which the transmitter is installed.
• If the measurement range 0% point is 0 kPa or
shifted in the positive direction (suppressed
zero), the reference pressure should be applied
as shown in the figure.
If the measurement range 0% point is shifted in
the negative direction (elevated zero), the
reference pressure should be applied using a
vacuum pump.
• Do not perform the calibration procedure until
the transmitter is at room temperature.
IMPORTANT
• As a rule, maintenance of this transmitter
should be implemented in a maintenance
service shop where the necessary tools are
provided.
• The CPU assembly contains sensitive parts
that may be damaged by static electricity.
Exercise care so as not to directly touch the
electronic parts or circuit patterns on the board,
for example, by preventing static electrification
by using grounded wrist straps when handling
the assembly. Also take precautions such as
placing a removed CPU assembly into a bag
with an antistatic coating.
2) Apply reference pressures of 0%, 50%, and 100% of
the measurement range to the transmitter. Calculate
the errors (differences between digital voltmeter
readings and reference pressures) as the pressure is
increased from 0% to 100% and is decreased from
100% to 0%, and confirm that the errors are within
the required accuracy.

Note: The above table contains the instruments capable of performing calibration to the 0.2% level. Since special maintenance and management
procedures involving traceability of each instrument to higher-level standards are required for calibration to the 0.1% level, there are
difficulties in calibration to this level in the field. For calibration to the 0.1% level, contact Yokogawa representatives from which the
instrument was purchased or the nearest Yokogawa office.

9.4.1 Replacing the Integral Indicator
CAUTION
This section describes procedures for disassembly and
reassembly for maintenance and component replacement.
Cautions for Flameproof Type Transmitters
Users are prohibited by law from modifying the
construction of a flameproof type transmitter.
This would invalidate the agency approval and
the transmitter’s use in such rated area.
Thus the user is prohibited from using a flameproof type transmitter with its integral indicator
removed, or from adding an integral indicator to
a transmitter. If such modification is absolutely
required, contact Yokogawa.
Always turn OFF power and shut off and release
pressures before disassembly. Use proper tools for all
operations. Table 9.4.1 shows the tools required.

CAUTION
Precautions for CENELEC and IECEx Flameproof Type Transmitters
• Flameproof type transmitters must be, as a
rule, removed to a non-hazardous area for
maintenance and be disassembled and reassembled to the original state.
• On the flameproof type transmitters the two
covers are locked, each by an Allen head bolt
(shrouding bolt). When a shrouding bolt is
driven clockwise by an Allen wrench, it is going
in and cover lock is released, and then the
cover can be opened by hand.
When a cover is closed it should be locked by a
shrouding bolt without fail. Tighten the shrouding bolt to a torque of 0.7 N·m.
This subsection describes the procedure for replacing
an integral indicator. (See Figure 9.4.2)
Removing the Integral Indicator
1) Remove the cover.
2) Supporting the integral indicator by hand, loosen its
two mounting screws.
3) Dismount the LCD board assembly from the CPU
assembly.
When doing this, carefully pull the LCD board
assembly straight forward so as not to damage the
connector pins between it and the CPU assembly.

Confirm that the zero-adjustment screw pin is
placed properly in the groove on the bracket
prior to tightening the two bosses. If it is not, the
zero-adjustment mechanism will be damaged.
IMPORTANT
Exercise care as follows when cleaning the
capsule assembly.
• Handle the capsule assembly with care, and be
especially careful not to damage or distort the
diaphragms that contact the process fluid.
• Do not use a chlorinated or acidic solution for

• Rinse thoroughly with clean water and dry
thoroughly after cleaning.
5) Replace the cover.
9.4.3 Cleaning and Replacing the Capsule
Assembly
This subsection describes the procedures for cleaning
and replacing the capsule assembly. (See Figure 9.4.3.)
CAUTION
Cautions for Flameproof Type Transmitters
Users are prohibited by law from modifying the
construction of a flameproof type transmitter. If
you wish to replace the capsule assembly with
one of a different measurement range, contact
Yokogawa.
The user is permitted, however, to replace a
capsule assembly with another of the same
measurement range. When doing so, be sure to
observe the following.
• The replacement capsule assembly must have
the same part number as the one being replaced.
• The section connecting the transmitter and
capsule assembly is a critical element in
preservation of flameproof performance, and
must be checked to verify that it is free of
dents, scratches, and other defects.
• After completing maintenance, be sure to
securely tighten the Allen screws that fasten
the transmitter section and pressure-detector
section together.
1) Remove the CPU assembly as shown in Subsection
9.4.2.
2) Remove the two Allen screws that connect the
transmitter section and pressure-detector section.
3) Separate the transmitter section and pressuredetector section.
4) Remove the nuts from the four flange bolts.
5) Hold the capsule assembly by hand and remove the
