SIL Certified Safety Manual for
Eclipse
Model 706-512X-XXX
®
High Performance uided Wave
Radar Level Transmitter
This manual complements and is intended to be used with the
Magnetrol
Eclipse
Model 706 High Performance Guided Wave
®
®
Radar Installation and Operating manual ( ulletin 57- 606).
Safety Function
The HART
version of the Eclipse
®
Guided Wave Radar (GWR) transmitter will measure
level and transmit a signal proportional to that level
within the stated safety accuracy of ±2% of span (or the
measured error published in I/O Manual 57- 606,
whichever is greater). In addition, when continuous,
automatic diagnostics detect that the transmitter cannot
perform this function, the output will be driven to the
customer-specified out-of-range signal (i.e., 3.6 mA or
21 mA).
The Enhanced Model 706 is certified for use in low
demand level measurement applications.
pplication
The HART
version of the ECLIPSE Model 706
®
Guided Wave Radar level transmitter can be applied in
most process or storage vessels, bridles, and bypass
chambers up to the probe's rated temperature and pres-
sure. It can be used in liquids, slurries, or solids with a
dielectric constant in the range 1.4–100 to meet the
safety system requirements of IEC 61508 (Edition 2.0,
2010) and IEC 61511-1.
Benefits
• Level protection to SIL 3 as certified by exida
Certification per IEC 61508/IEC 61511-1.
• Probe designs to +850 °F (+454 °C), 6250 psig
(430 bar) and full vacuum.
• Cryogenic applications to -320 °F (-190 °C).
• Intrinsically safe, Explosion-proof and Non-Incendive
approvals.
• Quick connect/disconnect probe coupling.

    Introduction Product Description The ECLIPSE Model 706 High Performance Guided Wave Radar Level Transmitter is a two-wire, loop-powered Table 1 24 VDC level transmitter based on Guided Wave Radar Enhanced ECLIPSE Model Numbers (GWR) technology. Transmitters: NOTE: For Safety Instrumented Systems usage, it is assumed that the Model 706, 706-512*-*** (HART) 4–20 mA output is used as the safety variable.

    • The only unsafe mode is when the unit is reading an incorrect level within the 4–20 mA range (> ±2% deviation). • MAGNETROL defines the faulted mode as one in which the 4–20 mA current is driven out of range (i.e., less than 3.8 mA or greater than 21.5 mA).

  • Page 5: Miscellaneous Electrical Considerations

    Miscellaneous Electrical Considerations Following are miscellaneous electrical issues to be considered in a safety system. 3.1.1 Pollution Degree 2 The ECLIPSE Model 706 transmitter is designed for use in a Category II, Pollution Degree 2 installation, which is defined by a nonconductive pollution of the sort where occasionally a temporary conductivity caused by condensation must be expected.

    Coaxial, twin flexible cable, and single element (rod or cable) are the three basic configurations. As the probe configuration establishes fundamental performance characteristics, the probe for use with the ECLIPSE Model 706 transmitter should be selected as appropriate for the application. The Model 706 is designed for use in many applications in process industries.

Select DIAGNOSTICS / ADVANCED DIAGNOSTICS / TRANSMITTER TESTS / Analog Output Test to change the output loop current and confirm the actual current matches the value chosen. a.) Send a HART command to the transmitter (or use the local interface) to go to the high alarm current output, 22 mA, and verify that the analog current reaches the valve.

    Safety Integrity Function, SIF. Magnetrol cannot directly control the user life cycle of a SIF using this product but needs to have assumptions on how the product will be used.

  • Page 12: Safety Function Requirements

    Safety Function Requirements This section lists the Safety Function Requirements that specify what safety relevant functionality is to be performed for implementation of the safety integrity function and also to maintain the desired level of safety integrity. These requirements may also rule out particular functionality for SIF usage that could lead to designs that are difficult to vali- date for deterministic performance or safety integrity.
