SIL Functional Safety Manual
for Pulsar
Software Version 1.x
Model R80
80GHz FMCW Radar
Level Transmitter
This manual complements and is intended to be used with
®
the Pulsar
Model R80 Installation and Operating manual
(Bulletin 58-604).
pplication
The Pulsar Model R80 (HART
Continuous Wave (FMCW) level transmitter can be
applied in most indoor and outdoor process or storage
vessels. The Pulsar Model R80 can be used in liquids or
slurries to meet the safety system requirements of IEC
61508.
Benefits
The Magnetrol
®
Model R80 (HART) transmitter pro-
vides the following benefits to your operation:
• Protection up to SIL2 as independently assessed
(hardware assessment) by exida as per IEC 61508.
Safe Failure Fraction: 92.3%
• Antenna designs to +400 °F (+200 °C),
-14.5 to 1000 psi (-1 to 70 bar)
• IS, XP and Non-Incendive approvals
• Quick connect / disconnect antenna coupling
• Performance not process dependent (changing specific
gravity and dielectric have no effect).

Page 3: Introduction
Introduction Product Description The Pulsar Model R80 Level Transmitter is a loop-pow- ® ered, 24 VDC level transmitter based on FMCW Radar Table 1 technology. For Safety Instrumented Systems usage, it is Pulsar ® Model Number assumed that the 4–20 mA output is used as the primary safety variable. -
Page 4: Level Measuring System
The use of the Pulsar Model R80 Radar Level Transmitter must be constrained by Table 3 in order to meet the mini- mum hardware fault tolerance architectural constraints for a SIL 2 safety function. 3. All products chosen for use in a SIF must be developed to at least the Systematic Capability corresponding to the SIF’s SIL, or by documenting an argument that justifies an equiv- alent systematic capability per the proven in use require-... -
Page 5: Miscellaneous Electrical Considerations
Miscellaneous Electrical Considerations Following are miscellaneous electrical issues to be considered. 2.2.1 Pollution Degree 3 The Pulsar system is designed for use in Category II, Pollution Degree 3 installations. The typical pollution degree used for equipment being eval- uated to IEC/EN 61010 is a nonconductive pollution of the sort where a temporary conductivity caused by conden- sation might be expected. -
Page 6: Instructions
Instructions Systematic Limitations The following factors must be observed to avoid systematic failures. 5.1.1 Application Choosing the proper Radar antenna is the most important step in the application decision process. The antenna con- figuration establishes fundamental performance characteris- tics. Therefore, the horn antenna for use with the Pulsar Model R80 should be selected as appropriate for the application. -
Page 7: Installation
Installation Refer to the Pulsar Model R80 Installation and Operating Manual Bulletin 58-604 for the proper installation instruc- tions. I/O Manual 58-604 contains information on the use, changing and resetting of the password protection function. I/O Manual 58-604 also provides menu selection items for configuration of the transmitter as a level sensing device and contains configuration recommendations. -
Page 8: Write Enabling / Unlocking
5.6.3 Write Enabling / Unlocking When the alterations to the system are complete, ensure the menu has been locked with the password to prevent inad- vertent changes to the device. Site cceptance Testing To ensure proper operation after installation and configura- tion a site acceptance test should be completed. -
Page 9: Recurrent Function Tests
Recurrent Function Tests Proof Testing 6.1.1 Introduction Following are the procedures utilized to detect Dangerous Undetected (DU) failures. The procedure will detect approximately 90% of possible DU failures in the Model R80. 6.1.2 Interval To maintain the Safety Integrity Level of a Safety Instrumented System, it is imperative that the entire system be tested at regular time intervals (referred to as TI in the appropriate standards). -
Page 10: Proof Test Procedure
6.1.4 Proof Test Procedure 1. Bypass the PLC or take other action to avoid a false trip. 2. Inspect the Unit in detail outside and inside for physical damage or evidence of environmental or process leaks. a. Inspect the exterior of the Unit housing. If there is any evidence of physical damage that may impact the integri- ty of the housing and the environmental protection, the unit should be repaired or replaced. - Page 11 i. This step tests for high quiescent current and supply voltage problems. ii. This also tests for current loop control circuitry and adjustment problems. c. Exit the “Analog Output Test” and confirm that the out- put returns to original state, with the proper loop current as indicated and controlled by the unit.

Page 15: Report- Lifetime Of Critical Components
Report: Lifetime of Critical Components According to section 7.4.9.5 of IEC 61508-2, a useful life- time, based on experience, should be assumed. Although a constant failure rate is assumed by the proba- bilistic estimation method, this only applies provided that the useful lifetime* of components is not exceeded. - Page 16 No claims for misapplication, labor, direct or consequen- tial damage will be allowed. 705 Enterprise Street • Aurora, Illinois 60504-8149 USA 630.969.4000 • info.magnetrol@ametek.com • magnetrol.com BULLETIN: 58-652.0 EFFECTIVE: July 2022 Copyright © 2022 AMETEK Magnetrol USA, LLC...
