transmitter from the control room, the transmitter
site, or any other wiring termination point in the
loop, provided there is a minimum of 250 Ω
between the connection and the power supply. To
communicate, it must be connected in parallel with
the transmitter; the connections are non-polarized.
Figure 2.2 illustrates the wiring connections for
direct interface at the transmitter site for the
DPharp. The HART conguration tool can be used
for remote access from any terminal strip as well.

2.6 Power Supply Voltage and Load Resistance
When conguring the loop, make sure that the
external load resistance is within the range in the
gure below.
(Note) With an intrinsically safe transmitter, external load
resistance includes safety barrier resistance.

Note that the Yokogawa default setting for the
standard temperature is 4°C (39.2°F). For the units
of mmH2O, inH2O, and ftH2O, the pressure varies
according to the standard temperature denition.
Select the appropriate unit with @68degF when a
standard temperature of 20°C (68°F) is required.

3.2.3 Range Change
The range values are factory-set as specied by
the customer. To change the range, follow the steps
below.
(1) Keypad input — LRV and URV
The measurement span is determined by the upper
and lower range values. In this method, the upper
and lower range values can be set independently,
and the span changes according to the range limit
values sent to the transmitter.
• Procedure to call up the display
DD and DTM

HART 5[1.2])
EJX_HART 5[1.2]
DTM
→ LRV Lower range value
→ URV Upper range value
[Root Menu] → Basic setup →
Re-range → Keypad input
Easy Setup → or Conguration →
Analog Output →
NOTE
The measurement span is determined by the upper
and lower range values. Changing the lower range
value causes the upper range value to change
automatically, keeping the span constant. If a
change in the lower range value causes the upper
range value to exceed the measuring limit of the
transmitter, an error message appears and the
transmitter holds the output signal right before the
error occurred. Enter the correct values within the
range of the sensor limits.
Note that changing the upper range value does
not cause the lower range value to change. Thus,
changing the upper range value also changes the
span.
3.2.4 Output Mode
The mode setting for the output signal and the
integral indicator can be performed independently.
The output mode for the output signal is set as
specied in the order when the instrument is
shipped. Follow the procedure below to change the
mode.
The calibration range can be set as LRV > URV
under the following conditions, reversing the 4
to 20 mA output signal. When using the integral
indicator, change the user set scale values
accordingly.
Conditions:
LSL ≤ LRV ≤ USL
LSL ≤ URV ≤ USL
|URV – LRV| ≥ Min Span
LSL: Lower sensor limit of range setting
USL: Upper sensor limit of range setting
(2) Apply values — changing the ranges while
applying an actual Input
This feature allows the lower and upper range
values to be setup automatically with the actual
input applied. If the upper and lower range values
are set, URV and LRV are changed at the same

3.2.6 Output Signal Low Cut Mode Setup
Low cut mode can be used to stabilize the output
signal near the zero point.
The low cut point can be set in a range from 0 to
20%, the direct ratio corresponding to the output
signal of 4 to 20 mA. (Hysteresis for the cut point:
±10% of the cut point)
Either “Linear” or “Zero” can be selected as the low
cut mode. Unless otherwise specied, the cut mode
is set to “Linear” at the factory.
The default value of Low cut is set according to the
combination of the Output mode (Xfer fnctn) and
Integral indicator display mode (Disp Pres % fnctn).

3.3.6 Sensor Trim
The transmitter is factory characterized. Factory
characterization is the process of comparing a
known pressure input with the output of each
transmitter sensor module over the entire pressure
and temperature operating range. During the
characterization process, this comparison
information is stored in the transmitter EEPROM. In
operation, the transmitter uses this factory-stored
curve to produce a process variable output (PV), in
engineering units, dependent on the pressure input.
The sensor trim procedure allows you to adjust
for local conditions, changing how the transmitter
calculates process variables. There are two ways
to trim the sensor: a zero trim and a full sensor trim.
A zero trim is a one-point adjustment typically used
to compensate for mounting position effects or
zero shifts caused by static pressure. A full sensor
trim is a two-point process, in which two accurate
end-point pressures are applied (equal to or greater
than the range values), and all output is linearized
between them.
(1) Zero Trim
a. Zeroing—Pres Zero trim
Pres Zero trim carries out the zero adjustment and
automatically sets the applied “0” input values to the
output value of “0”, keeping the span constant. Use
this setting when the LRV is known to be 0 mmH2O.

(2) Full Sensor Trim—Auto Trim and Manual
Trim
Full sensor trim is carried out by performing Auto,
Lower Pt followed by Auto, Upper Pt.
Also, you can manually perform the trimming
procedure with Manual, Lower Pt and Manual,
Upper Pt.
The full sensor trim is a two-point adjustment,
and the lower point adjustment should always be
performed before the upper point adjustment in
order to maintain the pitch between the zero and
100% points within the calibration range.
In the manual method, the reference pressure
should also be applied to the transmitter at both
the lower and upper points. Without the reference
pressure, Manual, Lower Pt and Manual, Upper
Pt may not represent the correct value for each
adjustment point.
a. Auto Sensor Trim
Applying reference pressure of 0% and 100% of the
measurement range to the transmitter, adjust the
lower and upper points automatically.

(Manual, Lower Pt).
−4.0+6.0=+2.0
<3> Enter the correction value of “2” to the Pres

<4> Call up the Pres UTD (Manual, Upper Pt).
<5> Suppose that a standard pressure of 3000

trim is 3015.0. Firstly, obtain the slope error for
the span as follows;
Slope Error = ×(URV−LRV)
Applied Pressure Value−Value of Pres for Trim
= × (3000−1000) = −10
Applied Pressure Value
3000−3015
3000
Then correct for this slope error of −10 by
adding −10 to Pres UTD (Manual, Upper Pt).
−3.0+(−10.0)=−13.0
<6> Enter the correction value of “−13” to the Pres
UTD (Manual, Upper Pt).

The transmitter congured data is saved by using a
write protection function. The write protection status
is set to “Yes” when 8 alphanumeric characters are
entered in the New password eld and transferred
to the transmitter.
When write protection is set to ”Yes,” the transmitter
does not accept parameter changes. When the
same eight alphanumeric string entered in the New
password eld is also entered in the Enable wrt
10min eld and transferred to the transmitter, it
will be possible to change transmitter parameters
during a 10 minute period.
To change the transmitter from the write protection
”Yes” status back to write protection ”No” status,
use Enable wrt 10min to rst release the write
protection function and then enter eight spaces in

This function is used to compensate the output
for non-linear applications. The characterized
values are applied to the 4-20 mA output. For
the measured pressure, a maximum of nine
coordinates can be specied between 0-100%.
Perform the coordinate settings while the S.C. at
S.C. menu parameter is “Disabled”.
To apply the settings to the output, set the S.C.
parameter to “Enabled”.
Note that the transmitter rejects the activation of the
function by AL. 60 with the following transmitter’s

4.2.2 Impulse Line Blockage Detection (ILBD)
ILBD is carried out by using statistical analysis
based on the measured values of process
uctuations that exist in a uid. An alarm on the
transmitter LCD display or an analog alert is
generated if blockage reaches a certain level.
The transmitter provides the following results as
blockage detection.
(1) A Blocking and B Blocking
These are blockage detections based on
the uctuation value change of differential
pressure/pressure. With a differential pressure
transmitter, each result indicates that both or
single side is plugged.
(2) L Side Blocking
It is a low-pressure side blockage detection
based on the change of BlkF or low-pressure-
side uctuation value.
(3) H Side Blocking
It is a high-pressure side blockage detection
based on the change of BlkF or high-pressure-
side uctuation value.
*: BlkF indicates blockage degree characterized
by a comparison of the high- and low-pressureside uctuation values. For the details, refer to
Figure 4.2.2.
4.2 Advanced Diagnostics
(Only for EJX series)
4.2.1 Multi-sensing Process Monitoring
Multi-sensing process monitoring function (option
code: /DG6) provides the advanced diagnostics
to detect the abnormal conditions in process
environment such as an impulse line etc. by using
the EJX multisensing technology and its unique
algorithm. There are following two functions.
Impulse Line Blockage Detection (ILBD)
The uctuation change of differential pressure and
static pressure is monitored by a silicone resonant
sensor and detects a potential blockage condition.
The differential pressure transmitter gives also a
result of which pressure-side was plugged.
Heat Trace Monitoring
The two temperature sensors built in the transmitter
calculate the ange temperature, the change of
which enables to detect the heat trace breakage or
the abnormal temperature due to the failure.
EJX
IMPORTANT
• The pressure uctuation amplitude in uids
must be sufciently large for blockages to be
detected.
• If the pressure uctuation amplitude is too
low for a reference value to be obtained,
blockages detection operation cannot be
performed with an alarm that the reference
value is invalid.
• The pressure uctuation amplitude may
decrease due to other causes unrelated with
a blockage according to process condition. In
above case, a false alarm of an impulse line
blockage may be generated. Before taking
action in response to a blockage alarm,
consider the plant operating conditions.
Notes for Pressure or Level
Measurement
With pressure or level measurement, the pressure
uctuation amplitude may reduce especially for the
following cases.
IM 01C25T01-06EN
<4. Diagnostics>
Pressure Measurement
• Operational pressure is near outside of
diagnostic range.
• Even though pressure is constant, the ow
decreases than that under normal condition.
• A source of pressure uctuation (pump,
compressor, blower, etc.) is shut down. As
a result, the pressure uctuation amplitude
decreases.
Level Measurement
• A transmitter is used to measure tank level and
the ow of uid into or out of the tank comes to
a stop.
• The agitator in the tank is shut down.
• A source of pressure variation (a compressor,
etc.) that controls the internal pressure of a
sealed (closed) tank is shut down.
Before taking action in response to a blockage
alarm, consider the plant operating conditions.

A/B Blocking Detection
“A Blocking” and “B Blocking” indicates the result
estimated from blockage degree based on the
difference of the high- and low-pressure-side
uctuation values. Ratio fDP, SQRT (fDP / Ref
fDP) is used to detect A/B blocking. Ref fDP is the
average value of the sum of squares of differential
pressure uctuations under normal condition.
As the value of Ratio fDP exceeds the value of
Lim fDPmax, EJX gives basically an alarm of “A
Blocking”. On the other hand, if this value is below
the value of Lim fDPmin, EJX gives an alarm of “B
parameter [1] to [10] as those of EJX110A.
H/L Blocking Detection
EJX differential pressure transmitter enables
to detect both-, a high-, or low-pressure-side
blockage. The blockage degree characterized
by a comparison of high-pressure side and lowpressure-side uctuation values, BlkF, is used to
detect it. The value changes within a range of –1
to +1. As BlkF approaches +1, the high-pressure-
side blockage progresses. On the other hand, if it
approaches –1, the low-pressure-side blockage
progresses.

As a high- or low-pressure-side blockage

blockages progress simultaneously, fDP decreases.
Therefore, “B Blocking” with a differential pressure
transmitter indicates that both-side impulse lines
are plugged.

L Side Blocking Detection
BlkF is preferentially used to "L Side Blocking"
detection. If BlkF cannot be used, Ratio fSPl,
SQRT (fSPl / Ref fSPl) is used to "L Side Blocking"
detection. Ref fSPl is the average value of the sum
of squares of low-pressure-side static pressure
uctuations under normal condition.
As the value of Ratio fSPl is below the value of Lim
fSPlmin, EJX gives an alarm of "L Side Blocking".
On the other hand, if this value exceeds the value of
Lim fSPlmax, EJX gives an alarm of “Large Fluct
L”.
H Side Blocking Detection
BlkF is preferentially used to "H Side Blocking"
detection. If BlkF cannot be used, Ratio fSPh,
SQRT (fSPh / Ref fSPh) is used to "H Side
Blocking" detection. Ref fSPh is the average value
of the sum of squares of high-pressure-side static
pressure uctuations under normal condition.
As the value of Ratio fSPh is below the value
of Lim fSPhmin, EJX gives an alarm of "H Side
Blocking".
4.2.2.2 Combination of Reference Result and Blockage Detection
Diag Applicable
The transmitter can detect four modes of impulse
line blockage: both-sides, high-pressure side, lowpressure side, and/or single-side and abnormal
uctuation when all the reference values are
properly measured. However, the detectable alarm
mode combination is limited when some of the
reference values are invalid. Available Blockage
Detection are shown in the below gure.
NOTE
• Ref fDP must be larger than the specied
level shown in Table 4.4 (refer to subsection
4.2.2.6). No blockage can be detected when
Ref fDP is not large enough.
• The plausibility of blockage detection needs
to be conrmed by blockage simulation test.
The simulation test can be performed by
the appropriate manifold operation (refer to
subsection 4.2.2.8).
On the other hand, if this value exceeds the value of
Lim fSPhmax, EJX gives an alarm of “Large Fluct
H”.
Large Fluctuation Detection
When a pump or compressor starts, the large
uctuation is generated as process condition
changes rapidly. This phenomenon affects process
uctuation measurement; so correct blockage
detection is not performed.
If “Large Fluct L” or “Large Fluct H” is detected,
consider whether a blockage result is correct.
The threshold values to detect large uctuation are
set to Lim fSPlmax and Lim fSPhmax.
Since these values are enough to detect large
uctuation, it is not almost necessary to change
them.

IMPORTANT
• For the each parameter, the one value is

again, the value is updated and overwritten.
• If the power supply is shut down during the
sampling, Diag Mode becomes “Stop”. Set
“Reference” to Diag Mode in order to carry
out the sampling again.
End of Sampling
After about 180 seconds, the sampling
automatically nishes. The “Reference” setting of
Diag Mode moves automatically to “Calculation”.
Conrm that the setting of Diag Mode moves to
“Calculation”.
fDP, fSPl and fSPh are enough.
All alarm modes can be detected even if BlkF is
not within the specied values.
4.2.2.7 Obtain Reference Values
The pressure uctuation values are reduced
when the impulse line is plugged. Therefore, the
reference value is required to determine the degree
of reduction.
IMPORTANT
• If the impulse line is about to be plugged at
the time when a reference value is obtained,
blockages cannot be detected accurately.
The impulse lines on both the high-pressure
and low-pressure sides need to be cleaned
before a reference value is obtained.
• All air bubbles need to be adequately purged
before a reference value is obtained.
• Reference values must be obtained under
operating condition.

4.2.2.8 Capability Test of Blockage Detection Operation
Before performing the ILBD operation, check the
capability of the blockage detection operation.
The simulation test is performed by closing motion
of a three-valve manifold or stop valve. When
simulated blockage occurs, conrm that an alarm is
generated.
NOTE
The uctuation amplitude of atmospheric
pressure is nearly zero with pressure or level
measurement. In such case, simulate the
blockage detection by closing the valve where
the uctuation existed.
Simulation of Low-pressure Side
Blockage
1) Close the low-pressure-side valve.
2) Conrm the value of Pres is stable. If not,
open the valve a little.
3) Set “Calculation” to Diag Mode so as to start
blockage detection operation.
4) Check that an alarm of “L Side Blocking” is
generated after the time that consists of Diag
Period and Diag Supp Count passed.
5) Check also the operation of the analog alert if
an analog alert is set.
6) Open the valve completely and check that
there are no alarms.
Simulation of Both-pressure Side
Blockage
1) Close the both-pressure-side valves.
2) Conrm the value of Pres is stable. If not,
open the valve a little.
3) Set “Calculation” to Diag Mode so as to start
blockage detection operation.
4) Check that an alarm of “B Blocking” is
generated in the Diag Error after the time
that consists of Diag Period and Diag Supp
Count passed.
5) Check also the operation of the analog alert if
an analog alert is set.
6) Open the valve completely and check that
there are no alarms.
4.2.2.9 Start ILBD Operation
If process condition and capability to detect a
blockage are conrmed, you can start the ILBD
operation according to the following procedure.
Simulation of High-pressure Side
Blockage
1) Close the high-pressure-side valve.
2) Conrm the value of Pres is stable. If not,
open the valve a little.
3) Set “Calculation” to Diag Mode so as to start
blockage detection operation.
4) Check that an alarm of “H Side Blocking” is
generated after the time that consists of Diag
Period and Diag Supp Count passed.
5) Check also the operation of the analog alert if
an analog alert is set.
6) Open the valve completely and check that
there are no alarms.
1) Check the value of sampling period (Diag
Period).
2) Check the number of times that detect the
blockage consecutively in order to give an
alarm (Diag Supp Count). The default value
at the shipment is set to 3 times.
3) Set “Calculation” to Diag Mode.
If the reference value has not yet been
obtained, set “Reference” to Diag Mode.
After obtained the reference values, the
ILBD starts automatically. At the same time,
Diag Mode changes automatically from
“Reference” to “Calculation”.

Sampling Period
If uctuating around the threshold value, an
alarm maybe often generated. When the above
phenomenon happens, the sampling time (Diag
Period) can be changed so as to enhance the
accuracy of the blockage detection.
The longer the sampling time, better the expected
accuracy.
(1) Set “Stop” to Diag Mode.
(2) Enter the value to Diag Period within the
range of 20 to 65535 (seconds).
Note: Set to “Calculation” after setting the parameter.
Also, the accuracy can be improved by increasing
the number of Diag Supp Count.
ILBD Range Setting
If ow/differential pressure is less than the default
threshold value of Lim DPAvgmin, pressure
uctuation is not large enough to detect the
blockage. To prevent the fault blockage detection,
the threshold should be changed to larger value.
(1) Set “Stop” to Diag Mode.
(2) Enter the value to Lim DPAvgmin or Lim
DPAvgmax.
Note Set to “Calculation” after setting the parameter.
Ratio fDP Compensation
When the ow change is too large or small, an
alarm maybe often generated. When the above
case happens, the Ratio fDP can be compensated
so as to enhance the accuracy of the blockage
detection.

4.2.3 Heat Trace Monitoring
The transmitter with Heat trace monitoring function
calculates the ange temperature by using the two
temperature sensors built in the transmitter.
An analog alert is generated if the temperature
reached to the preset level.
The ange temperature is based on the following
parameters and calculation formula.
[Parameters]
Parameter name Explanation
Snsr temp (CT) Measured capsule temperature
value
Amp temp (AT) Measured amplier temperature
value
Flg temp (FT) Flange temperature value
(Calculated value)
Flg Temp Coef (Cf) Coefcient to calculate ange
temperature
Flg Temp Hi Alert Val Threshold to generate FT high
alarm
Flg Temp Lo Alert Val Threshold to generate FT low
alarm
[Calculation formula]
Flg temp (FT) = CT + Cf X (CT-AT)
If the ange temperature exceeds the value preset
to Flg Temp Hi Alert Val or Flg Temp Lo Alert Val,
an alert is generated.
4.2.3.1 Flg Temp Coef Setting
The value calculated according to the following
procedure is set to Flg Temp Coef.
• To enhance the calculation accuracy of the
ange temperature, measure the actual ange
temperature by using the temperature sensor
etc.
• Calculate the ratio of the capsule temperature
to the capsule temperature minus the amplier
temperature from the two temperature values
measured by the transmitter.
• Derive the Flg Temp Coef from the measured
ange temperature and the ratio of the capsule
temperature to the amplier temperature in
accordance with the following calculation
formula.
Flg Temp Coef (Cf) =
(Actual measured value of Flange temperature) - CT
CT - AT
For DTM (HART 5), Flg Temp Coef parameter can
be set by using Tuning function.
By setting the measured value of ange
temperature, Flg Temp Coef is calculated by using
capsule temperature and amplier temperature.
• Procedure to call up the Tuning display.
Diag and Service → Advanced Diag Conguration →
Heat Trace → Tuning
NOTE
The ange temperature is calculated by the
calculation formula assumed that the capsule
part of the transmitter is heated up or kept warm
by an electrical heater or steam. In the case of an
atmosphere temperature or less, the difference
of temperature of approximately 3 to 4 °C,
may occur because the amplier temperature
becomes higher than the capsule temperature.

<Appendix1. Safety Instrumented Systems Installation>
A1-1
Appendix 1. Safety Instrumented Systems
Installation
The calibration of the transmitter must be performed
WARNING
after parameters are set.
The contents of this appendix are cited from
exida.com safety manual on the transmitters
specically observed for the safety transmitter
purpose. When using the transmitter for Safety
Instrumented Systems (SIS) application, the
instructions and procedures in this section must
be strictly followed in order to preserve the
transmitter for that safety level.
A1.1 Scope and Purpose
This section provides an overview of the user
responsibilities for installation and operation of
the transmitter in order to maintain the designed
safety level for Safety Instrumented Systems (SIS)
applications. Items that will be addressed are proof
testing, repair and replacement of the transmitter,
reliability data, lifetime, environmental and
application limits, and parameter settings.
A1.2 Using the transmitter for an
SIS Application
A1.2.1 Safety Accuracy
The transmitter has a specied safety accuracy
of 2%. This means that the internal component
failures are listed in the device failure rate if they will
cause an error of 2% or greater.
A1.2.2 Diagnostic Response Time
The transmitter will report an internal failure within 5
seconds of the fault occurrence.
A1.2.4 Required Parameter Settings
The following parameters need to be set in order to
maintain the designed safety integrity.
Table A1.1 Required Parameter Settings
Item Description
Burnout direction
switch
Write protection
switch
To specify if the output should go
21.6 mA or higher or 3.6 mA or lower
upon detection of an internal failure.
The write function should be
disabled.
A1.2.5 Proof Testing
The objective of proof testing is to detect failures
within the transmitter that are not detected by the
diagnostics of the transmitter. Of main concern
are undetected failures that prevent the safety
instrumented function from performing its intended
function. See table A1.2 for proof testing method.
The frequency of the proof tests (or the proof
test interval) is to be determined in the reliability
calculations for the safety instrumented functions
for which the transmitter is applied. The actual
proof tests must be performed more frequently or
as frequently as specied in the calculation in order
to maintain required safety integrity of the safety
instrumented function.
The following tests need to be specically executed
when a proof test is performed. The results of
the proof test need to be documented and this
documentation should be part of a plant safety
management system. Failures that are detected
should be reported to Yokogawa.
A1.2.3 Setup
During installation the transmitter must be setup
with engineering units parameters. This is typically
done with a handheld terminal. These parameters
must be veried during the installation to insure
that the correct parameters are in the transmitter.
Engineering range parameters can be veried by
reading these parameters from the optional local
display or by checking actual calibration of the
transmitter.
The personnel performing the proof test of the
transmitter should be trained in SIS operations
including bypass procedures, transmitter
maintenance, and company management of
change procedures.
IM 01C25T01-06EN
<Appendix1. Safety Instrumented Systems Installation>
Table A1.2 Proof Testing
Testing method Tools required Expected outcome Remarks
Functional test:
1. Follow all Management of Change
procedures to bypass logic solvers if
necessary.
2. Execute HART/BRAIN command to
send value to high alarm (21.5 mA) and
verify that current has reached this level.
3. Execute HART/BRAIN command to
send value to low alarm (3.6 mA) and
verify that current has reached this level.
4. Restore logic solvers operation and
verify.
Perform three point calibration along with
the functional test listed above.
• Handheld terminal Proof Test Coverage
=52%
• Handheld terminal
• Calibrated pressure
source
Proof Test Coverage
=99%
The output needs to be
monitored to assure that the
transmitter communicates
the correct signal.
A1-2
A1.2.6 Repair and Replacement
If repair is to be performed with the process online
the transmitter will need to be bypassed during the
repair. The user should setup appropriate bypass
procedures.
In the unlikely event that the transmitter has a
failure, the failures that are detected should be
reported to Yokogawa.
When replacing the transmitter, the procedure in the
installation manual should be followed.
The personnel performing the repair or replacement
of the transmitter should have a sufcient skill level.
A1.2.7 Startup Time
The transmitter generates a valid signal within 1
second of power-on startup.
A1.2.8 Firmware Update
In case rmware updates are required, they
will be performed at factory. The replacement
responsibilities are then in place. The user will not
be required to perform any rmware updates.
A1.2.9 Reliability Data
A detailed Failure Mode, Effects, and Diagnostics
Analysis (FMEDA) report is available from
Yokogawa with all failure rates and failure modes.
The development process of the transmitter is
certied up to SIL3, allowing redundant use of
the transmitter up to this Safety Integrity Level,
depending the PFDavg calculation of the entire
Safety Instrumented Function.
When using the transmitter in a redundant
conguration, the use of a common cause factor
(β-factor) of 2% is suggested. (However, if the
redundant transmitters share an impulse line or if
clogging of the separate impulse lines is likely, a
common cause factor of 10% is suggested.)
Note that the failure rates of the impulse lines need
to be accounted for in the PFDavg calculation.
A1.2.10 Lifetime Limits
The expected lifetime of the transmitter is 50
years. The reliability data listed the FMEDA report
is only valid for this period. The failure rates of the
transmitter may increase sometime after this period.
Reliability calculations based on the data listed in
the FMEDA report for transmitter lifetimes beyond
50 years may yield results that are too optimistic,
i.e. the calculated Safety Integrity Level will not be
achieved.
A1.2.11 Environmental Limits
The environmental limits of the transmitter are
specied in the user’s manual IM 01C25.
The transmitter is certied up to SIL2 for use
in a simplex (1oo1) conguration, depending
on the PFDavg calculation of the entire Safety
Instrumented Function.
A1.2.12 Application Limits
The application limits of the transmitter are specied
in the user’s manual IM 01C25. If the transmitter is
used outside of the application limits, the reliability
data listed in A1.2.9 becomes invalid.
