Functional Safety – Safety Instrumented Systems for the Process Industry Sector2 DEVICE DESCRIPTIONThe One Series Safety Transmitter senses the temperature or pressure of a system and provides control outputs that are used to monitor or shut down that system before an unsafe condition occurs. An externally excited 4-20mA provides an analog indication of the process for use by a safety PLC. The solid state relay output provides direct control or shut down of a final element based on programmed operating modes and limits. The Switch Status output is a discrete output that mirrors the function of the solid state relay output. The IAW output isa discrete output based on self diagnostics that provides the user with anindication of device health. Any diagnostic failure that causes an IAW fault will force all outputs to the fail-safe state. All outputs of the One Series Safety Sensor operate in DTT (De-energize To Trip) mode.Detailed information on the installation, programming and operation of the OneSeries Safety Transmitter along with System Context Diagrams may be found indocument IM_ONE_SAFETY-01.3 DESIGNING A SIF USING THE ONE SERIES SAFETY TRANSMITTER3.1 Safety FunctionThe 4-20 mA, I Am Working, Safety Relay and Switch Status outputs have been assessed for safety instrumented systems usage.The achieved SIL level of the designed function must be verified by the designer. 3.2 Environmental limitsThe designer of a SIF must check that the product is rated for use within the expected environmental constraints. Refer to the United Electric Controls One Series ST-B-01 bulletin for environmental limits.3.3 Application limitsThe materials of construction of the One Series Safety Transmitter are specified in the United Electric Controls One Series ST-B-01 bulletin. It is especially important that the designer check for material compatibility considering on-site conditions. If the One Series Safety Transmitter is used outside of the application limits or with incompatible materials, the reliability data provided become invalid.3.4 Design VerificationA detailed Failure Mode, Effects, and Diagnostics Analysis (FMEDA) report isavailable from United Electric Controls. This report details all failure rates and failure modes as well as the expected lifetime.The achieved Safety Integrity Level (SIL) of an entire Safety Instrumented Function (SIF) design must be verified by the designer via a calculation of PFD AVG considering architecture, proof test interval, proof test effectiveness, any automatic diagnostics, average repair time and the specific failure rates of all products included in the SIF. Each subsystem must be checked to assure compliance with minimum hardware fault tolerance (HFT) requirements. The exida exSILentia® tool is recommended for this purpose as it contains accurate models for the One Series Safety Transmitter and its failure rates.When using the One Series Safety Transmitter in a redundant configuration, a common cause factor of at least 5% should be included in safety integrity calculations.The failure rate data listed in the FMEDA report are only valid for the useful lifetime of the One Series Safety Transmitter. The failure rates will increase sometime after this time period. Reliability calculations based on the data listed in the FMEDA report for mission times beyond the lifetime may yield results that are too optimistic, i.e. the calculated Safety Integrity Level will not be achieved.3.5 SIL Capability3.5.1 Systematic IntegrityThe product has met manufacturer design process requirements of Safety Integrity Level (SIL) 3. These are intended to achieve sufficient integrity against systematic errors of design by the manufacturer. A Safety Instrumented Function (SIF) designed with this product must not be used at a SIL level higher than stated without “prior use” justification by the end user or diverse technology redundancy in the design.3.5.2 Random IntegrityThe One Series Safety Transmitter is a Type B Device. Therefore, based on the SFF between 90% and 99%, when the One Series Safety Transmitter is used as the only component in a sensor element subassembly, a design can meet SIL 2 @ HFT=0.When the sensor element assembly consists of multiple components the SIL must be verified for the entire assembly using failure rates from all components. This analysis must account for any hardware fault tolerance and architecture constraints.3.5.3 Safety ParametersThe safety accuracy of the device is 3% of the operating range.For detailed failure rate information refer to the Failure Modes, Effects and Diagnostic Analysis Report for the One Series Safety Transmitter.3.6 Connection of the One Series Safety Transmitter to the SIS Logic-solverThe One Series Safety Transmitter is connected to the safety rated logic solver via a NAMUR NE 43 4-20 mA analog and up to two discrete diagnostic status outputs.The logic solver is actively performing the safety function by monitoring and interpreting the One Series Safety Transmitter outputs, designed to diagnose potentially dangerous process conditions and failures within the One Series Safety Transmitter via the I Am Working (IAW) diagnostic.The One Series Safety Transmitter may also be configured to provide the safety function directly without connections to a safety rated logic solver.Please refer to the System Context Diagrams in document IM_ONE_SAFETY-01 for details on using the various logic outputs on the One Series Safety Transmitter.3.7 General RequirementsThe system’s response time shall be less than the process safety time. The One Series Safety Transmitter, Switch Status and Safety Relay Outputs will move to its safe state in less than 100 milliseconds under specific delay filter settings. The 4-20mA output shall stabilize to 90% of a step response within 250mSec under specific delay filter settings. For available settings and a description of the delay filter operation document refer to the product installation and maintenance manual IM_ONE_SAFETY-01.The diagnostic interval for the One Series Safety transmitter is less than 10 seconds.All SIS components including the One Series Safety Transmitter must be operational before process start-up. At power up, there may be a brief delay before the outputs are stable. The user must consider this in the application and not rely on the One Series Safety Transmitter for the control of the Safety Instrumented System until the outputs have stabilized. The time from power on until the outputs are stable shall be less than 10 seconds.User shall verify that the One Series Safety Transmitter is suitable for use in safety applications by confirming the One Series Safety Transmitter’s nameplate is properly marked.Personnel performing maintenance and testing on the One Series Safety Transmitter shall be competent to do so.Results from the proof tests shall be recorded and reviewed periodically.The useful life of the One Series Safety Transmitter is discussed in the Failure Modes, Effects and Diagnostic Analysis Report for the One Series Safety Transmitter.4 INSTALLATION AND COMMISSIONING4.1 InstallationThe One Series Safety Transmitter must be installed per standard practices outlined in the Installation Manual.The One Series Safety Transmitter must not be modified.The environment must be checked to verify that environmental conditions do not exceed the ratings.The One Series Safety Transmitter must be accessible for physical inspection.Detailed programming and operating instructions are found in the One Series Safety Transmitter Installation and Maintenance Instructions manual (IM_ONE_SAFETY-01). It is the responsibility of the SIF designer to validate all device settings either through test or by re-entering the programming menu and reading back all settings. The checklist in Appendix A provides a place to record all device settings as they are read back. While in the programming menu all outputs are forced to the fail safe state:4-20mA Output <3.6mASwitch Status OffSafety Relay Output OffIAW OffThe Plugged Port Detection and Safety Relay Fault Monitor are turned off from the factory. If these features are desired they must be enable using the programming menu. Reference One Series Safety transmitter Installation and Maintenance Instructions manual (IM_ONE_SAFETY-01) for details.4.2 Physical Location and PlacementThe One Series Safety Transmitter shall be accessible with sufficient room for connections and shall allow manual proof testing.Piping to the One Series Safety Transmitter shall be kept as short and straight as possible to minimize restrictions and potential clogging. Long or kinked tubes may also increase the response time.The One Series Safety Transmitter shall be mounted in a low vibration environment. If excessive vibration can be expected special precautions shall be taken to ensure the integrity of connectors or the vibration should be reduced using appropriate damping mounts.4.3 ConnectionsConnections to the One Series Safety Transmitter are to be made per the Installation and Maintenance Instructions (IM_ONE_SAFETY-01).Recommended methods for process connections to the One Series Safety Transmitter can be found in the installation and maintenance manual IM_ONE_SAFETY-01. The length of tubing between the One Series Safety Transmitter and the process connection shall be kept as short as possible and free of kinks.5 OPERATION AND MAINTENANCE5.1 Proof test without automatic testingThe objective of proof testing is to detect failures within the United Electric Controls One Series Safety Transmitter that are not detected by any automatic diagnostics of the instrument. Of main concern are undetected failures that prevent the safety instrumented function from performing its intended function.The frequency of proof testing, or proof test interval, is to be determined in reliability calculations for the safety instrumented functions for which a United Electric Controls One Series Safety Transmitter is applied. The proof tests must be performed at least as frequently as specified in the calculation in order to maintain the required safety integrity of the safety instrumented function.The following proof test is recommended. The results of the proof test should be recorded and any failures that are detected and that compromise functional safety should be reported to United Electric Controls. The suggested proof test consists of simulating a process upset and injecting a fault of the One Series Safety Transmitter and observing the reaction of the SIF to these upsets.Table1: Recommended Proof TestStep Action1.Bypass the safety PLC or take other appropriate action to avoid a false trip.2.Verify the correct output under normal conditions. The Safety Relay Output,SRO Status and IAW Output will be in the closed state. The 4-20 mA outputwill provide a proportional signal to the process variable.3.Change the process variable or change the programming of the instrument sothat the Safety Relay Output changes to the tripped state (opens). Verify thatthe Safety Relay Output and SRO Status opens and the IAW Output remainsclosed. The 4-20 mA output will provide a proportional signal to the processvariable.4.Change the process variable so that the IAW Output goes to the fault state(opens). (Extreme Over Range of 150% of the sensor’s range is suggested.)Verify that the IAW Output opens and the 4-20 mA output provides <3.6 mA.5.Restore the normal input values or programming. Verify that the outputs havereturned to their non-tripped (closed) state. Verify that the 4-20 mA output isproportional to the process variable.6.Restore the loop to full operation.7.Remove the bypass from the safety PLC or otherwise restore normal operation.This test will detect >99% of possible DU failures in the One Series Safety Transmitter.The person(s) performing the proof test of a One Series Safety Transmitter should be trained in SIS operations, including bypass procedures, maintenance and company Management of Change procedures. A 2mm hex wrench is required to remove the cover. The Software Flow Chart from the One Series Safety Transmitter installation and maintenance manual IM_ONE_SAFETY-01 is required to change the programming.5.2 Repair and replacementRepair and replacement procedures for the One Series Safety Transmitter are obtained by contacting United Electric Controls technical support at 617-923-6977 or ************************.A complete list of fault codes for the One Series Safety Transmitter may be found inthe installation and maintenance manual IM_ONE_SAFETY-01.5.3 Hardware and Software ConfigurationThe model number of the device is found on the PART# field on the device nameplate.Hardware and software revisions are noted on the label located on the back of the displaymodule.5.4 Useful LifeThe useful life of the One Series Safety Transmitter is 50 years.5.5 MANUFACTURER NotificationAny failures that are detected and that compromise functional safety should be reported to United Electric Controls.

超声波传感器一、产品简介利用声波介质对被检测物进行非接触式和无磨损的检测。
超声波传感器对无论是透明性的物体还是有颜色的物体，金属物体或者非金属物体、以及固体、液体或是粉状物质，均能检测。
周围环境条件如有烟环境、灰尘环境或是下雨条件下几乎都不会影响超声波传感器的检测性能。
二、超声波测距原理发射超声换能器发射出的超声脉冲，通过传播媒质传播到被测介质，经反射后再通过传声媒质返回到接收换能器，测出超声脉冲从发射到接收在传声媒质中传播的时间。
再根据传声媒质中的声速，就可以算得从换能器到介质面的距离。
从而确定液位。
因此我们可以计算出探头到反射面的距离D ＝ C*t/2(除以2是因为声波从发射到接收实际是一个来回，D是距离，C是声速，t是时间）。

The DIL switch must be set to MIN for minimum detection in a SIL application.Settings for Nivotester FTL325N-#3#3 (three-channel version):Observe the following for the Nivotester FTL325N-####: The operator must use suitablemeasures (e.g. current limiter, fuse) to ensure the relay contact characteristics are not exceeded:•U ≤ 253 V AC 50/60 Hz , I ≤ 2 A, P ≤ 500 VA at cos ϕ ≥ 0,7 or •U ≤ 40 V DC, I ≤ 2 A, P ≤ 80 WChanges to the measuring system and settings after start-up can impair the protection function!Liquiphant M/S with FEL56 and Nivotester FTL325N10Endress+HauserResponse in operation and failureThe response in operation and failure is descriped in the documentation, which can be found in the section "Supplementary device documentation", ä7.RepairIn the event of failure of a SIL-labeled Endress+Hauser device, which has been operated in a protection function, the "Declaration of Contamination and Cleaning" with the corresponding note "Used as SIL device in protection system" must be enclosed when the defective device is returnedRecurrent function tests of the measuring systemThe operativeness of the minimum detection must be checked annually if the PFD av values given in the Appendix are used.The check must be carried out in such a way that it is proven that the minimum detection functions perfectly in interaction with all components. This is guaranteed when the response height is lowered in an emptying process. If it is not practical to empty to the response height, suitable simulation of the level or of the physical measuring effect must be used to make the level sensor respond.If the operativeness of the level sensor/transmitter can be determined otherwise (exclusion of faults that impair function), the check can also be completed by simulating the corresponding output signal.In the case of recurrent tests, each permitted setting must be checked, especially whether all the alarm switches are set to ON.Note the following points for the function test:•Each individual channel must be checked e.g. by lowering the level.•Relay contact switching can be checked by using a hand multimeter at the terminals or by observing the minimum detection components (e.g. horn, adjuster).•In multi-channel devices, all channels which do not carry out a safety function must beincluded in the recurrent function tests if faulty functioning cannot be detected by any other means.•As a positive test result, an uncovered tuning fork must be detected and trigger the alarm for minimum detection.•If fork uncovering is not detected during the recurrent test, the monitored process must be set to a safe state by means of additional or other measures and/or kept in the safe state until the safety system is repaired.AppendixSpecific values and wiring options for the measuring system The tables show the specific values and wiring options for the measuring system.Note the following points on the tables below:•The PFD av values for multichannel systems already contain common cause failures for theassociated wiring scheme.•The PFD av values are only valid for the associated wiring scheme. Wiring schemes other than those shown in the Appendix were not assessed and thus do not bear any information relevant to safety. Using NC contacts instead of NO contacts requires further consideration of theinstallation means.•The wiring scheme shows the number of devices (Liquiphant and Nivotester) and the limitrelay contact circuits (open, when the sensor signals uncovering).•Fault messaging (circuit break/short-circuit) must be switched on for each channel thatperforms a safety function.•With several devices in a wiring scheme, they all indicate the same displayed settings.For safety related use of the Liquiphant M/S for MIN detection, the following application errors must be excluded:•Permanent and/or heavy build-up or "non-Newtonian media"•Solid proportions of the medium with a diameter > 5,0 mm (0.2in)•Corrosion: The Liquiphant may only be used in media to which the process-wetted parts are resistant. If coated sensors are used, measures must therefore be taken to ensure that there is no damage during installation and operation.The errors may cause that the demand mode of the safety function is not detected and theLiquiphant will not switch as intended.Exida Management SummaryExida Management Summary 2Exida Management Summary 1Exida Management Summary 4 Exida Management Summary 3Supplementary Documentation Safety in the Process Industry - reducing risks with SIL CP01008Z/11/EN.Liquiphant M/S with FEL56 and Nivotester FTL325NEndress+Hauser21Liquiphant M/S with FEL56 and Nivotester FTL325N 22Endress+HauserLiquiphant M/S with FEL56 and Nivotester FTL325NEndress+Hauser2371238762。
