HANDLING CAUTIONS
This chapter describes important cautions regarding
how to handle the transmitter. Read carefully before
using the transmitter.
2.1 Model and Specifications
Check
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.
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.
Also check that all transmitter mounting hardware
shown in Figure 2.1.1 is included. If the transmitter
was ordered without the mounting bracket, the transmitter mounting hardware is not included. After
checking the transmitter, repack it in the way it was
delivered until installation.

2.2 Unpacking
Adapter
When moving the transmitter to the installation site,
keep it in its original packaging. Then, unpack the
transmitter there to avoid damage on the way.
2.3 Storage
The following precautions must be observed when
storing the instrument, especially for a long period.
U-bolt (L)
U-bolt (S)
U-bolt nut (L)
F0201.EPS
Figure 2.1.1 Transmitter Mounting Hardware
(a) Select a storage area which meets the following
conditions:
• It is not exposed to rain or water.
• It suffers minimum vibration and shock.
• It has an ambient temperature and relative
humidity within the following ranges.
Ambient temperature:
–40 to 85°C without integral indicator
–30 to 80°C with integral indicator
Relative humidity:
5% to 100% R.H. (at 40°C)
Preferred temperature and humidity:
approx. 25°C and 65% R.H.
(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 body, so
that no measured fluid remains in it. Also make
sure before storing that the transmitter assemblies
are securely mounted.
2-1
IM 1C21F1-01E
2. HANDLING CAUTIONS
2.4 Selecting the Installation
Location
The following precautions must be observed in order to
safely operate the transmitter under pressure.
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.
(a) Make sure that the process connection part is
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.
(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.
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
(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).
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.
(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 connection
part to avoid the dangerous spouting of process
fluid.
• During draining condensate from the capsule
assembly, 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.
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.
2-2
IM 1C21F1-01E
2. HANDLING CAUTIONS
(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.
2.9 Installation of Explosion
Protected Type
WARNING
(c) Before conducting these tests, disconnect all signal
lines from the transmitter terminals. Perform the
tests in the following procedure:
To pressure the safety of explosionproof equipment requires great care during mounting,
wiring, and piping. Safety requirements also
place restrictions on maintenance and repair
activities. Please read the following sections very
carefully.
• 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 shortcircuiting SUPPLY terminals. Leave this resistor
connected at least one second to discharge any
static potential. Do not touch the terminals while it
is discharging.

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.

IMPORTANT
5.1.2 Routing the Impulse Piping
For the transmitter specified as Measurement
span code A (10 to 200 kPa) and Process
connection code 7 (1/2 NPT male), verify that
the space between the process fluid level and
the end of the impulse piping is more than 13
mm (0.5 inch), in order to avoid the sensor
damage from tightening. See Figure 5.1.1a.
(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.
NOTE
Process fluid
• 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.

5. INSTALLING IMPULSE PIPING
5.2 Impulse Piping Connection
Examples
(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.
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.
Note the following points when referring to these
piping examples.
• 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.
• 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.
(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.
(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
After completing the connections, close the valves

valves at the transmitter (stop valves), and the
impulse piping drain valves, so that condensate,

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
SAA 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

of 0% (0 kPa, atmospheric pressure);
7.2 Zero Point Adjustment
Adjust the zero point after operating preparation is
completed.
For pressure measurement using gauge pressure
transmitters, follow the step below before zero point
adjustment.
1) Close the tap valve (main valve).
2) Loosen the fill plug so that the pressure applied to
the transmitter is only the head of the seal liquid.
3) Adjust the zero point at this status.
4) After the adjustment, close the fill plug and then
gradually open the tap valve.
IMPORTANT
Do not turn off the power to the transmitter
immediately after a zero adjustment. Powering
off within 30 seconds after a zero adjustment will
return the adjustment back to the previous
settings.
The zero point adjustment can be made in either way:
using the zero-adjustment screw of the transmitter or
the BT200 operation.
j Using the Transmitter Zero-adjustment
Screw
Before adjusting a screw, check that the parameter
J20: EXT ZERO ADJ displays ENABLE. See
Subsection 8.3.3 (11) for the setting procedure.
For output signal checking, display the parameter A10:
OUTPUT (%) in the BT200.
•BT200
• Use a slotted screwdriver to turn the zero-adjustment
screw. Turn the screw clockwise to increase the
output or counterclockwise to decrease the output.
The zero point adjustment can be made with a
resolution of 0.01% of the setting range. Since the
degree of zero adjustments varies with the screw
turning speed, turn the screw slowly for fine adjustment and quickly for coarse adjustment.

Zero point can be adjusted by simple key operation of
the BT200.
Select parameter J10: ZERO ADJ, and press the
ENTER key twice. The zero point will be adjusted
automatically to the output signal 0% (4 mA DC).
Confirm that the setting value displayed for the
parameter is ‘0.0%’ before pressing the ENTER key.

After reviewing this parameter you are prepared to
adjust the zero point. When making the zero adjustment on a pressure transmitter, the process pressure
value does not have to be set to the low limit of the
measurement range (0%). In such case, adjust the
transmitter output signal to the actual measured value
obtained from a high-accuracy pressure measuring
instrument.

7.3 Starting Operation
After completing the zero point adjustment, follow the
procedure below to start operation.
Convert the actual measured value obtained by a digital
manometer or a glass gauge into %.
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.
[Example]
The measuring range of 50 to 250 kPa; the actual
measured value of 130 kPa.
Actual measured value=
130–50
250–50
x 100=40.0%
j Using the Transmitter Zero-Adjustment Screw
Turn the screw to match the output signal to the actual
measured value in %.

j Using the BT200
Select the parameter J10: ZERO ADJ. Change the

• 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 SAA 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 94) After locking, the covers should be confirmed not to be opened by hands.

7. OPERATION
7.5 Setting the Range Using the
Range-setting Switch
IMPORTANT
• 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 /E integral indicator plate and the external
zero-adjustment 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]
Rerange LRV to 0 and HRV to 3 MPa.
Integral indicator
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.
6) Press the range-setting push-button. The integral
indicator then displays “HSET.”
7) Apply a pressure of 3 MPa to the transmitter. (Note 1)
8) Turn the external zero-adjustment screw in the
desired direction. The integral indicator displays the
output signal in %. (Note 2)
9) Adjust the output signal to 100% (5 V DC) by
rotating the external zero-adjustment screw. Doing
so completes the HRV setting.
10) Press the range-setting push-button. The transmitter
then switches back to the normal operation mode
with the measurement range of 0 to 3 MPa.
Note : Use a thin bal which
has a blunt tip, e.g.,
a hexagonal wrench,
to press the rangesetting push-button
Range-setting switch
(Push-button)
F0707.EPS
Figure 7.5 Range-setting Switch
Note 1: Wait until the pressure inside the 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.”

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 even after dismounting the instrument
from the process line for maintenance.
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
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.
Since the transmitters are precision instruments,
carefully and thoroughly read the following sections
for proper handling during maintenance.
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.
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.
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

CAUTION
Precautions for CENELEC and SAA 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.

CAUTION
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.
This section describes procedures for disassembly and
reassembly for maintenance and component replacement.
Always turn OFF power and shut off and release
pressures before disassembly. Use proper tools for all
