2. CONDITIONS OF COMMUNICATION LINE

2. CONDITIONS OF COMMUNICATION

LINE

2.1 Interconnection Between YTA

and BT200

WARNING

Do not attempt to use the BT200 in a dangerous environment where explosive gas or inflammable vapor is generated.

The BRAIN communication signal is superimposed onto the 4 to 20 mA DC analog signal. Since the modulated wave is a communication signal, superimposing it on the normal signal will, from basic principles, cause no error in the DC component of the analog signal. Thus, monitoring can be performed via the BT200 while the transmitter is on-line.

As shown in Figure 2.1, there are two methods of connecting the transmitter and the BT200: the first is to use the BT200 connection hook provided in the terminal box and the other is to use a terminal board or relay terminals on the transmission line.

Load impedance : 3.3 mH or less Communication distance: 2 km (1.25 mile), when

CEV cable is used

Distance from the power line:

Output signal line : 15 cm (5.9 inch) or more

(do not use parallel wiring)

Input signal line : 100 cm (39.8 inch) or more

(do not use parallel wiring)

Input impedance of receiver connected to receiving resistor: 10 kΩ more (at 2.4 kHz)

3.2.2 Process Variables Mapping

Process variable mapping;

B10: PV is, B20: SV is, B30: TV is, B40: 4V is

Process variables can be assigned as the primary variable(PV), the secondary variable(SV), the tertiary variable(TV), and the quaternary variable(4V). The PV always outputs a 4 to 20mA DC analog signal corresponding to Lower Range Value and Upper Range Value. Mapping process variables to the SV, TV, and 4V is optional.

The following items can be mapped as the process variables.

Sensor1 : Sensor1 input value. Sensor2 : Sensor2 input value. DIFFERENCE

*1,*2,*4

: Difference between

Sensor1 and Sensor2.

(Sensor1-Sensor2 or

Sensor2-Sensor1; specified in B05: SET DIFF)

variable is not assigned.

*1: This item is displayed only when the YTA320 2-input

temperature transmitter is used. *2: The setting in B05 applies to the PV, SV, TV, and 4V. *3: “Not used” is not displayed for B10 since the PV

requires process variable mapping. *4: When this item is selected, the sensor types to be set

for D10(Sensor1) and E10(Sensor2) should be

selected from any one of the following three groups;

Temperature sensor(T/C and RTD), DC voltage or

resistance. The combination(for example, temperature

sensor and DC voltage input) would cause an incorrect

computation due to the different unit system and is not

allowed. *5: When this item is selected, DC voltage and resistance

input should not be set for D10(Sensor1) or

E10(Sensor2).

● Example: Use two temperature sensors to map the difference (Sensor2-Sensor1) between Sensor1 and Sensor2 to the PV (the primary variable). Before mapping the process variable, complete the setting of the temperature sensor to be connected to Sensor1 and Sensor2.

3.2.5 Setting Damping Time Constant

B12: PV DAMPING, B22: SV DAMPING, B32: TV DAMPING, B42: 4V DAMPING

Setting the response time of each Process Variable to make the output change very slowly with a rapid change in input. Set the value from 0 to 99 seconds.

If the time constant is set to 2 seconds, the transmitter calculates a reading every cycle using the damping equation, in order to make the output 63 percent of the input range after 2 seconds.

This damping time constant is normally set to work when the temperature make a step change within 2 percent of the output range. The damping can be changed using the “B13: PV DMP POINT” parameter.

● Setting Damping Holding Point

B13: PV DMP POINT

This parameter is used to set the point where the transmitter conducts the PV damping operation, depending on a magnitude of the change in the input value. When the change value in percent exceeds the setting value, the transmitter outputs the signal without the damping operation. Set the value as a percent of span.

If the transmitter is equipped with the integral indicator, the LCD displays “Abn.” and “OUT” as shown in Figure 3.2.

H10: REVERSE OUT

To reverse the direction for a 4 to 20 mA DC output relative to input.

3.2.11 Sensor Backup Function (For Model YTA320)

IMPORTANT

To use sensor backup function, the following conditions must be met.

• “Sensor1” is mapped as the PV at B10: PV is.

• “Sensor2” is mapped as the SV at B20: SV is.

• “Sensor1” and “Sensor2” are both correct input status.

• “HIGH, LOW, User mA, or User %” is selected in the sensor burnout parameter setting at F40: BURN OUT

The sensor backup command sets the transmitter to automatically use Sensor2 as PV if Sensor1 fails. When the transmitter is in the Sensor Backup operation and switches to Sensor2, there will be no disruption in the 4 to 20 mA output. The error code for Sensor1 failure is shown on the integral indicator, and also the error message is sent to the BT200 that the Sensor1 failed and the sensor backup has been in operation. In case Sensor2 fails during the backup operation, the

3-10

IM 01C50T03-01E

3. OPERATION

transmitter will send the error code for Sensor2 failure to the integral indicator and the BT200, and outputs the “Sensor burnout” value.

(a) Setting of backup mode

H20: SNSR BACKUP

Set “ENABLE” at H20: SNSR BACKUP.

ENABLE : Activates backup mode, and

transmitter starts to observe.

DISABLE : Cancels backup mode.

IMPORTANT

Do not change the PV and SV mapping data when the sensor backup mode is active. Cancel the sensor backup mode to alter the mapping data.

(b) Returning from Sensor2 to Sensor1 during

the sensor backup operation

H21: RETURN SNS1

Once the transmitter enters the sensor backup operation, H21:RETURN SNS1 appears on the BT200. This parameter is used to retrieve the output to the Sensor1 input value. Ensure that Sensor1 and Sensor2 are both correct input status, then;

Set “ENABLE” at H21:RETURN SNS1.

ENABLE : Switches to Sensor1 output. DISABLE : Maintains Sensor2 output status.

SET PRAM ONLY : Uploads the parameters

with respect to the operation settings such as LRV and the sensor type.

ALL PRAM : Uploads the all param-

eters.

See the parameter list at the end of this manual for classification of the operation setting parameter groups and the parameter group unique to the equipment. See also the BT200 instruction manual, IM 1C0A11-01E, for the setting procedure.

3.2.13 Write Protect Function

(a) Software Write Protect Function

H40: WRITE PROTCT

The write protect function is used to prevent unauthorized configuration data changes in the transmitter.

YES : Disables writing of all parameters

other than H40.

NO : Enables writing of all param-

eters.

If the transmitter is equipped with the integral indicator, the LCD displays “W.P.” when setting H40 to YES.

● Example: Setting write protect on

SET H40:WRIT PROTCT NO <NO > <YES >

1. Select “YES” and press [ENTER] twice to enter the setting.

ESC

IMPORTANT

In the sensor backup operation, even if the Sensor1 recovers, the Sensor2 input value continues to be output until “ENABLE” is set at H21: RETURN SNS1 or the transmitter's power is turned off and then on again.

3.2.12 Copy the Setting Data

H30: UPLOAD SELCT

This function is used to copy the setting data of one temperature transmitter to another.

Connect the temperature transmitter with the BT200 and record (UPLOAD) the setting data to the BT200 nonvolatile memory. By connecting the BT200 to other temperature transmitters, recorded data can be overwritten (DOWNLOAD) on the transmitters.

The YTA series temperature transmitter handles the uploading data at two levels. It is necessary to specify the desired one before uploading data.

(b) Hardware Write Protect Function

Hardware write protect function is set up by Switch (SW2) on the CPU assembly. Under write protect status, any change operation is denied. If the transmitter is equipped with the integral indicator, the LCD displays “W.P.” when setting SW2 to “Y”.

4. SELF-DIAGNOSTICS

The temperature transmitter continually monitors its own performance during normal operation. If an error occurs, it displays and records the error to the logging parameters, and with the integral indicator, an error code corresponding to the error is displayed.

4.1 Error Message

An error message is displayed on the BT200 when there is a problem with functions. The error message can be checked with the parameter number of each item ■60:SELF CHECK. In addition, the error code is displayed when the transmitter is equipped with the integral indicator. See Table 4.1 below for the error contents corresponding to the error messages, error codes, and their countermeasures.

4.2 Warning

1) Warning and contents

The YTA series has a warning display function. The warning display function displays a warning when

there is an incorrect use status such that a setting is out of the specified range. Also, when the instrument is operated in other than standard operation mode, that status is displayed as a warning. Factory default setting is to not display the warning. To display the warning, set parameter H55: WARNING ENBL. Use parameter I59: WARNING to confirm the warning. See Table 4.2 for contents corresponding to warnings and countermeasures.

2) Setting warning display

Classified warnings can be displayed with H55: WARNING ENBL. The warning is classified as follows.

Setting : Occurs when an inappropriate

parameter setting is used such as out of the specification range of the transmitter.

Operation : Occurs when the input value for

the parameter setting is out of the setting range.

Special : Occurs when the parameter of a

function unique to the YTA is set during forced output operation or reverse output operation.

4.3 Logging Function

The YTA series has the capability to store useful information for trouble shooting.

4.3.1 Error Log

Up to four error histories are stored in the transmitter memory. The transmitter records an error that continues to occur for more than 6 minutes.

P20:ERR LOG 1

This parameter records the latest errors that occurred.

P21:ERR LOG 2

This parameter records the last errors that have occurred.

P22:ERR LOG 3

This parameter records the 2nd to last error.

P23:ERR LOG 4

This parameter records the 3rd to last error.

P24: ERR LOG CLR ...... Error log clear processing

Clears all error logging data.

The % value is calculated from the number of BCC errors that occurred in BRAIN communication reception frame and the number of transmissions/receptions.

Turning the power off clears the data.

*1 : This parameter should display the 0 % in normal operation. If

it consistently displays other than that, check the cable wiring for the transmitter.

*2 : BBC = BRAIN Communication Check.

4.3.2 Min/Max Log

Minimum and Maximum values of the process variables and terminal temperature are stored in the transmitter memory. The logged data for the process variables except for the terminal temperature is reset at every power off.

To clear the logging data for process variables, select “ENABLE” at P05: ERR LOG CLR.

4.3.3 Operation Time

P30: OPERATE TIME

The transmitter’s operation time from the last power up is counted. The information is reset at every power off. The accuracy of time counting is not guaranteed. It is simply a reference.

4.3.4 Power Check

P31: POWER CHECK

By setting this parameter to START after power up, the transmitter can be checked to see if a temporary loss of power has occurred. This parameter is always reset to STOP at power off.

4.3.5 BRAIN communication BCC error occurrence rate

P40: BCC ERROR %

Displays the BCC error occurrence rate of BRAIN communication.

APPENDIX B. THE SENSOR MATCHING FUNCTION

APPENDIX B. THE SENSOR MATCHING

FUNCTION

B.1 Specifications

Function: The sensor-specific constants can be programmed into the transmitter.

Applicable model: YTA310 /CM1, YTA320 /CM1 RTD sensor: Pt100, Pt200, Pt500

Significant temperature measurement accuracy improvement can be attained using a temperature sensor that is matched to a temperature transmitter. This matching process entails teaching the temperature transmitter the relationship between resistance and temperature for a specific RTD sensor. This relationship, approximated by the Callendar-Van Dusen equation, is described as:

Rt = R0 {1 +  ( 1 + 0.01 ) t -  / 104 t2 -  / 10 ( t - 100 ) t3 }

where:Rt = Resistance (ohms) at Temperature t (C)

R0 = Sensor - Specific Constant (Resistance at t = 0 C)

B = Sensor - Specific Constant C = Sensor - Specific Constant (0 at t > 0 C)

These two equations are equivalent. A model YTA can cope with either case above-mentioned.

IMPORTANT

There is the following limitations for R0, , , , A, B, and C with the YTA.

•IT is necessary to enter the value, which is normalized by the exponential part specified for each parameter. See Table B.1.

• It is necessary to enter the value, which is rounded off to three or two decimal places

specified for each parameter. See Table B.1.

• When a three decimal place data is entered, it may be automatically changed to the four decimal place data that is equivalent to the input data.

Example: +3.809 E-3 → +3.8089 E-3

 = Sensor - Specific Constant  = Sensor - Specific Constant  = Sensor - Specific Constant (0 at t > 0 C)

The exact values for R0 , , , and  are specific to each RTD sensor, and are obtained by testing each individual sensor at various temperatures. These constants are known as Callendar-Van Dusen constants.

Generally the constants R0, A, B, and C are also being used as the characteristic coefficients of the sensor instead of R0, , , and . These are derived from the IEC Standard Curve and the relationship is described as:

Rt = R0 [ 1 + At + Bt2 + C ( t - 100 ) t3 ] where:Rt = Resistance (ohms) at Temperature t (C)

R0 = Sensor - Specific Constant (Resistance at t = 0 C)

A = Sensor - Specific Constant

APPENDIX B. THE SENSOR MATCHING FUNCTION

B.2 Operations (The Sensor

Matching Function)

IMPORTANT

This function is effective only in three kinds of sensors, Pt100, Pt200, and Pt500. Input relations between the sensor type and the value of R0 properly. When Pt100 is specified as an input type, the value close to 100 must be set to R0. When Pt500 is specified as input type, the value close to 500 must be set to R0. When the sensor type was changed, the Sensor Matching Parameters must be set up again or the Sensor Matching function must be set to “DISABLE”.

Example: To set Pt200, 3wire sensor as “Sensor 1”

input.

And to input R0, , , and  values, as

sensor-specific constants.

APPENDIX C. SAFETY INSTRUMENTED SYSTEMS INSTALLATION

APPENDIX C. SAFETY INSTRUMENTED

SYSTEMS INSTALLATION

WARNING

The contents of this appendix are cited from exida.com safety manual on the YTA series pressure transmitters specifically observed for the safety transmitter purpose. When using the YTA 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.

C.1 Scope and Purpose

This section provides an overview of the user responsibilities for installation and operation of the YTA 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.

C.2 Using the YTA for an SIS

Application

C.2.1 Safety Accuracy

The YTA has a specified 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.

C.2.2 Diagnostic Response Time

The YTA will report an internal failure within 8 seconds of the fault occurrence.

C.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 verified during the installation to insure that the correct parameters are in the transmitter. Engineering range parameters can be verified by reading these parameters from the optional local display or by checking actual calibration of the transmitter.

The calibration of the transmitter must be performed after parameters are set.

C.2.4 Required Parameter Settings

The following parameters need to be set in order to maintain the designed safety integrity.

Table C.2.4 Required Parameter Settings

Item

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.

Description

TA0101.EPS

C.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 C.2.5 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 YTA is applied. The actual proof tests must be performed more frequently or as frequently as specified in the calculation in order to maintain required safety integrity of the safety instrumented function.

The following tests need to be specifically 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.

The personnel performing the proof test of the transmitter should be trained in SIS operations including bypass procedures, YTA temperature transmitter maintenance, and company management of change procedures.

C-1

IM 01C50T03-01E

Table C.2.5 Proof Testing

Testing method Tools required Expected outcome Remarks

Analog Output Loop Test:

1. Bypass the safety PLC or take other appropriate action to avoid a false trip.

2. Send a HART or BRAIN command to the transmitter to go to the high alarm current output and verify that the analog current reaches that value.

3. Send a HART or BRAIN command to the transmitter to go to the low alarm current output and verify that the analog current reaches that value.

4. Use the HART or BRAIN communicator to view detailed device status to ensure no alarms or warnings are present in the transmitter.

5. Perform reasonability check on the sensor value(s) versus an independent estimate (i.e. from direct monitoring of BPCS value) to show current reading is good.

6. Restore the loop to full operation.

7. Remove the bypass from the safety PLC or otherwise restore normal operation.

Analog Output Loop Test and Temperature Spot Check:

1. Bypass the safety PLC or take other appropriate action to avoid a false trip.

2. Perform Analog Output Loop Test.

3. Verify the measurement for two temperature points.

4. Perform reasonability check of the housing temperature.

5. Restore the loop to full operation.

6. Remove the bypass from the safety PLC or otherwise restore normal operation.

APPENDIX C. SAFETY INSTRUMENTED SYSTEMS INSTALLATION

• Handheld terminal Proof Test Coverage =61%

• Handheld terminal Proof Test Coverage =96%

The output needs to be monitored to assure that the transmitter communicates the correct signal.

TA0102.EPS

C.2.6 Repair and Replacement

If repair is to be performed with the process online, the YTA will need to be bypassed during the repair. The user should setup appropriate bypass procedures.

In the unlikely event that the YTA has a failure, the failures that are detected should be reported to Yokogawa.

When replacing the YTA, the procedure in the installation manual should be followed.

The personnel performing the repair or replacement of the YTA should have a sufficient skill level.

C.2.7 Startup Time

The YTA generates a valid signal within 5 seconds of power-on startup.

C.2.8 Firmware Update

In case firmware 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 firmware updates.

IM 01C50T03-01E

APPENDIX C. SAFETY INSTRUMENTED SYSTEMS INSTALLATION

C.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 YTA is certified up to SIL2 for use in a simplex (1oo1) configuration, depending on the PFDavg respectively PFH calculation of the entire Safety Instrumented Function.

The development process of the YTA is certified up to SIL3, allowing redundant use of the transmitter up to this Safety Integrity Level, depending the PFDavg respectively PFH calculation of the entire Safety Instrumented Function.

When using the transmitter in a redundant configuration, the use of a common cause factor (-factor) of 5% is suggested. If the owner-operator of the plant would institute common cause failure training and more detailed maintenance procedures for avoiding common cause failure, a beta factor of 2% would be applicable.

C.2.10Lifetime Limits

The expected lifetime of the YTA is 50 years. The reliability data listed in the FMEDA report is only valid for this period. The failure rates of the YTA may increase sometime after this period. Reliability calculations based on the data listed in the FMEDA report for YTA lifetimes beyond 50 years may yield results that are too optimistic, i.e. the calculated Safety Integrity Level will not be achieved.

C.2.11Environmental Limits

The environmental limits of the YTA are specified in the user’s manual IM 01C50B01-01E.

C.2.12Application Limits

The application limits of the YTA are specified in the user’s manual IM 01C50B01-01E. If the transmitter is used outside of the application limits, the reliability data listed in C.2.9 becomes invalid.
