Up to 63 transmitters can be connected when set in the multidrop mode. To activate multidrop communication, the transmitter address must be changed to a number from 1 to 63. This change deactivates the 4 to 20 mA analog output, sending it to 4 mA. The alarm current is also disabled.

4.1.2 Checking with Integral Indicator NOTE If an error is detected by running self-diagnostics, an error number is displayed on the integral indicator. If there is more than one error, the error number changes at three-second intervals. See table 4.3.1 regarding the alarm codes. F0401.ai Figure 4.1 4-2 <4.

<4. Diagnostics> 4-4 IMPORTANT • The pressure fluctuation amplitude in fluids must be sufficiently large for blockages to be detected. • If the pressure fluctuation 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 fluctuation amplitude may decrease due to other causes unrelated with a blockage according to process condition.
4-5 <4. Diagnostics> Functional block diagram The figure below shows the functional block diagram of ILBD.
4.2.2.1 Blockage Detection Limit parameter When the parameter based on pressure fluctuation exceeds the preset value, EJX diagnoses an impulse line as blockage and gives an alarm. The threshold values are set to Limit parameter shown in below table.
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 fluctuation values, BlkF, is used to detect it. The value changes within a range of –1 to +1. As BlkF approaches +1, the high-pressureside blockage progresses. On the other hand, if it approaches –1, the low-pressure-side blockage progresses.
4-8 <4. Diagnostics> 4.2.2.2 Combination of Reference Result and Blockage Detection Diag Applicable An EJX multivariable transmitter can detect four modes of impulse line blockage: both-sides, highpressure side, low-pressure side, and/or single-side and abnormal fluctuation 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 figure.
4.2.2.3 Operation Parameters Diag Mode Diag Mode gives the directive for the ILBD operation. There are following three modes. • Procedure to call up the display DD (HART 5/7) [Root Menu] → Diag/Service → Diag DTM (HART 7) Parameters → ILBD Parameters → Configuration → Set Diag Mode → DTM (HART 5) Diag and Service → Advanced Diag Configurations → Impulse Line Blockage Detection → Diag Mode → Diag Mode Mode Stop Function The blockage detection operation is stopped.

Diag Supp Count (Number of times: 3) Time F0406.ai Figure 4.4 Relationship of Diag Supp Count and Alarm The number of detection to give an alarm is set for each blockage detection function. The default value at the shipment is set to three times.
4-11 <4. Diagnostics> 4.2.2.4 Operating Procedure If an alarm is often generated or the process condition changed in the ILBD operation, do tuning to change the alarm setting, or to reset the reference values. The basic flow of the ILBD operation is as follows. 1) Initial setting 2) Condition check 3) Start up 4) Perform the ILBD algorithm. Fill out the information to the checklist, at the process shown in below figure. (Refer to the Appendix 1.
<4. Diagnostics> 4.2.2.5 Alarm and Alert Setting The abnormal results as the blockage detection and high/low flange temperature (heat trace monitoring) are given through an analog alert or the LCD display of alarm status. Before performing the ILBD operation, it is necessary to set the alarm and alert according to the following procedure.
When the level range that can be measured by the transmitter with 100 kPa span is –80 to 80 kPa, the limits are set as follows. • Lim DPAvgmax: 0.80 • Lim DPAvgmax: –0.80 1.000 ILBD over range 0.
• Procedure to call up the display DD (HART 5/7) [Root Menu] → Diag/Service → Diag DTM (HART 7) Parameters → Diag Output → Diag Fixed Out Val → DTM (HART 5) Diag and Service → Advanced Diag Configurations → Diag Output → Diag Out Option → Status Output for Advanced diagnostic The output of the abnormal results are applicable for a transistor output (open collector) of an on/off signal according to the status of high and low alarm limits, which are values set to Limit parameters as shown in subsection
fDP is not enough. No blockage can be detected if fDP is not larger than the specified value. Only fDP is enough. “A Blocking” or “B Blocking” can be detected if fSPl and fSPh are not larger than specified values. fDP and fSPl are enough. “H Side Blocking” and “Large Fluct H” can not be detected if fSPh is not larger than specified value. fDP and fSPh are enough. “L Side Blocking” and “Large Fluct L” can not be detected if fSPl is not larger than specified value.
Invalid Ref F, SPH, SPL, or DP When the enough reference fluctuation value is not obtained, an alarm of invalid reference value for each parameter is generated and also the ILBD operation is not carried out. Confirm the alarm of Invalid Ref F, SPH, SPL, or DP is not displayed in Diag Error. If an alarm of Invalid Ref F, SPH, SPL, or DP is generated, consider the process condition or obtain the reference fluctuation values again.
4.2.2.10 Tuning (1) For DD (HART 5/HART 7) and DTM (HART 7) When the pressure fluctuation amplitude in fluids is not sufficiently large or an alarm is often generated according to the process condition, tune up by changing the threshold for the blockage detection (Limit parameters) or the sampling period (Diag Period) to enhance the accuracy of the blockage detection The ILBD operation must be stopped to tune up. Set “Stop” to Diag Mode.

Safety Instrumented Systems Installation WARNING The contents of this appendix are cited from exida.com safety manual on the EJX series pressure transmitters specifically observed for the safety transmitter purpose. When using the EJX 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.

Table A1.2 A1-2 Proof Testing Testing method Functional test: 1. Follow all Management of Change procedures to bypass logic solvers if necessary. Tools required • Handheld terminal Expected outcome Remarks Proof Test Coverage The output needs to be =52% monitored to assure that the transmitter communicates the correct signal. • Handheld terminal • Calibrated pressure source Proof Test Coverage =99% 2.

A2-1 Appendix 2. ILBD Check List Fill out the below checklist according to the operation flow of the ILBD in order to keep the important information for the blockage detection. Checklist (1/5) No. 1 Items 4-20 mA Analog Signal Setting • Select the output mode when an alarm is generaed.
A2-2 Checklist (2/5) No. 8 Items Alarm status • Check the alarm status shown in Diag Error. • Check that the alarm status of “ILBD over range” is not shown in Diag Error. 9 ILBD parameters • Record the values of parameters for ILBD operation. • Check the status of parameters for ILBD operation. *: Record the value after checked that the status of each parameter is “GOOD”.
A2-3 Checklist (3/5) Go to the following step according to the result of "Invalid Ref xx" shown in the Diag Error of 8th check item. Invalid Ref SPH Diag Error Invalid Ref SPL Invalid Ref DP → → Check item 10-a 10-b : The alarm is generated. : The alarm is not generated. No.
A2-4 Checklist (4/5) No. Items 10-a-2 L Side Blocking • Close the low-pressure side valve completely. • Record the values of fDP, fSPl, fSPh, BlkF, and DPAvg after the certain time, (Diag Period X Diag Supp Count), passed. *: Record the value after checked that the status is “GOOD”. • Record the status of Checkbox in Diag Option. • Check that the alarms status of “A Blocking” and “L Side Blocking” are set.
A2-5 Checklist (5/5) No. 10-b Items Simulation of Blockage detection operation • Close completely the valve for the side where the alarm of Invalid Reference Value is not generated. For the case that the high-pressure side value is closed; Parameters Result Example fDP* 7.48562E-09 fSPh* 7.14085E-09 fDP* 7.48562E-09 fSPI* 7.23277E-09 • Record the values of fDP, fSPl, fSPh, BlkF, and DPAvg after the certain time, (Diag Period X Diag Supp Count), passed.
