Safety Function

Primary Safety Functions
The HONEYWELL ST 800 & ST 700 measure the (pressure gauge, differential, absolute) of a process and reports the measurement with a safety accuracy of 2%.

Secondary Safety Functions
The HONEYWELL ST 800 & ST 700 performs automatic diagnostics to detect internal failures and reports these failures via out-of-band signals on the 4 – 20 mA output. The transmitter needs a power cycle for recovery from this condition.

Systematic Integrity: SIL 3 Capable

• SIL 3 Capability:
• The 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 the statement without “prior use” justification by end user or diverse technology redundancy in the design. This is a Type B device.

Designing with the HONEYWELL ST 800 & ST 700

Diagnostic Response Time
The HONEYWELL ST 800 & ST 700 will report an internal failure within 15 minutes of fault occurrence (worst case). The transmitter will be put to burnout current if.

1. PV is not updated in 7 seconds
2. The current is not as expected in 40 seconds
3. An Electronics fault is found in 15 minutes

The transmitter needs a power cycle for recovery from this condition.

Logic Solver Inputs

The logic solver must be configured so that the engineering range in the transmitter matches the expected range of the logic solver.
To take advantage of the internal diagnostics in the ST 800 & ST 700, the logic solver must be configured to annunciate an out-of-band current reading (greater than 20.8 mA. or less than 3.8 mA.) in standard configuration or (greater than 20.5 mA. or less than 3.8 mA.) with Namur configuration as a diagnostic fault. The logic solver configuration must consider the slew time of the current signal and ensure that filtering is used to prevent a false diagnostic failure annunciation.

Reliability data and lifetime limit

• A detailed Failure Mode, Effects, and Diagnostics Analysis (FMEDA) report is available from HONEYWELL. This report details all failure rates and failure modes, common cause factors for applications with redundant devices, and the expected lifetime of the HONEYWELL ST 800 & ST 700.
• The HONEYWELL ST 800 & ST 700 is intended for low-demand mode applications up to SIL 2 for use in a simplex (1oo1) configuration, depending on the PFDAVG calculation of the entire Safety Instrumented Function. ST 800 & ST 700 is classified as type B device according to IEC61508, having a hardware fault tolerance of 0.
• The development process of the HONEYWELL ST 800 & ST 700 is certified up to SIL3, allowing redundant use of the transmitter up to this Safety Integrity Level, depending on the PFDAVG calculation of the entire Safety Instrumented Function.
• When using the HONEYWELL ST 800 & ST 700 in a redundant configuration, a common cause factor should be included in reliability calculations. For reliability calculation details, useful lifetime, and SFF, see the FMEDA report.
• The reliability data listed in the FMEDA report is only valid for the useful lifetime of the HONEYWELL ST 800 & ST 700. The failure rates of the HONEYWELL ST 800 & ST 700 may increase sometime after this 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.

Environmental limits

The environmental limits of the HONEYWELL ST 800 & ST 700 are specified in the customer spec sheets as given in the below table.

Refer to the ST 700 Series Pressure Transmitter User’s manual, 34-ST-25-44 for information on Standard and Basic transmitter types.

Application limits
The application limits of the HONEYWELL ST 800 & ST 700 are specified in the User Manual. If the transmitter is used outside of the application limits the reliability data provided becomes invalid.

Installation with the HONEYWELL ST 800 & ST 700

A person with knowledge of safety operations will be required to do the installation and operation. No special installation is required in addition to the standard installation practices outlined in the ST 800 & ST 700 Smart Transmitter User Manual. However please note that when the device is in safety operation the optional write protect must be set in hardware and software both so that the device is write protected and HART® devices must be disconnected. This can be done using the write protect jumper. See ST 800 & ST 700 Smart Transmitter User Manual for details concerning the write-protect jumper. The software write protect is also available in the device with a password to disable the software write protect. The default password is “0000”. It can be enabled/disabled through the HART host. IEC 61508 Ed. 2.0 compliant hardware/software revisions for the ST 800 & ST 700 can be found in the Exida and TÜV Certification Reports. This document can be downloaded using the following link:

https://honeywell/public/Support/vault/support/Public/Documents/SmartLineHARTPressureFirmwareRevisions.zip.

The Test (- +) terminals may be used during the installation of the transmitter as a gross current loop check without disconnecting the current loop wiring. To use this feature, place a current meter with low resistance (~10 ohms) across the TEST (- +) terminals. As shown in Figure 4-1.

NOTE: During SIL operation, the TEST (- +) terminals should not be used to monitor the loop current.

Parameter settings

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

mA Fault action (Upscale/Downscale)| The transmitter is shipped with a default failsafe direction of upscale (21.0 mA). This is acceptable for all high-trip applications. For low-trip applications, the fail-safe direction is downscale (3.6 mA.). A jumper on the transmitter may be changed to accomplish this action, see the User Manual.
---|---
Engineering Range| All engineering range parameters must be entered to match the trip points in the safety logic solver. These parameters must be verified during the installation and commissioning to ensure that the correct parameters are set in the transmitter. Engineering range parameters can be verified by reading these parameters from the local display or by checking the actual calibration of the transmitter.

Operation and Maintenance with the HONEYWELL ST 800 & ST 700

Proof test

The objective of proof testing is to detect failures within the HONEYWELL ST 800 & ST 700 that are not detected by the automatic diagnostics of the transmitter. Of main concern are undetected failures that prevent the safety instrumented function from performing its intended function. The frequency of proof testing, or the proof test interval, is to be determined in reliability calculations for the safety instrumented functions for which the HONEYWELL ST 800 & ST 700 is applied. The Exida exSILentia® tool is recommended for these calculations. The proof tests must be performed more frequently than, or 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. It consists of a simple HART® driven min to max output test. The results of the proof test need to be documented and this documentation should be part of a plant safety management system. Any failures that are detected and that compromise functional safety should be reported to the Global Technical Support Center (GTS). See ST 800 & ST 700 Smart Transmitter User Manual for more details.

trip, following Management of Change procedures.
2| Send a HART® command to the transmitter to go to the high alarm current output and verify that the analog current reaches that value.

This procedure tests for compliance voltage problems such as a low loop power supply voltage or increased wiring resistance. This also tests for other possible failures.

3| Send a HART® command to the transmitter to go to the low alarm current output and verify that the analog current reaches that value. This test checks for possible quiescent current-related failures.
4| Use the HART® communicator to view detailed critical and non-critical device status to ensure no alarms or warnings are present in the transmitter.
5| Verify all safety-critical configuration parameters.
6| The WP jumper state should be checked to see if it is in WP mode first, and then changed to Enable configuration to ensure a change is detected by the device while configuring, and then moved back to WP after the configuration is complete. Then it should be verified again.
7| Calibrate the device as per the calibration procedure given below.
8| Restore the loop to full operation.
9| Remove the bypass from the safety PLC or otherwise restore normal operation.

This test will detect approximately 74% of possible DU failures in the transmitter (Proof Test Coverage). An alternative proof test consisting of proof test 1 with actual three-point pressure calibration plus verification of the temperature measurement will detect approximately 99% of possible DU failures. The person(s) performing the proof test of the HONEYWELL ST 800 & ST 700 should be trained in SIS operations, including bypass procedures, transmitter maintenance, and company Management of Change procedures. The tools required are handheld communicators.

Calibration procedure

The transmitter should be taken out of service. The source for the input pressure must be very precise, and certified for correct operation.

Remote Parameter Configuration Verification

• When configuring the HONEYWELL ST 800 or ST 700 through a remote host, it is recommended that parameters that affect the 4-20ma analog output be verified using an alternate utility, before using the transmitter in an SIS. This helps to ensure that the parameters that are entered remotely by the host are not inadvertently changed from the user’s intended values.
• The procedure can consist of listing the parameters and their values entered in the host application. Then, using an alternative application, the same parameters are read back and noted in the same form. The form is then signed, dated, and filed for future reference. See Table 1 – Example Verification Form for an example of this form.

Note that using the same host application to verify the remotely entered values will not provide as much assurance as using an alternate application.

Table 1 – Example Verification Form

Security Guidelines

1. Ensure the device has Hardware/ Software write protection enabled the device to prevent any unauthorized configuration changes.
2. Physical access to the device: A malicious operation on the transmitters will result in system shutdown, starting the system expectedly or impacting process control. For maximum security, the transmitter device must be protected against unauthorized physical access.
3. Be aware of any unauthorized access of a secondary master alarm present in Distributed Control System (DCS). If this is because of a secondary handheld device being connected then this can be ignored.
4. Enable the Tamper alarm and monitor the Tamper Counter value for unintended changes.
