Model R96 SIL Functional Safety Manual
2.2.2 Overvoltage
The MAGNETROL Model R96 has over-voltage protec-
tion per CE requirements. When considering Hi-pot, Fast
Transients and Surge, this protection is to 1000 volts.
Therefore, there should be no unsafe failure modes up to 1 KV.
Overvoltage Category II is a local level, covering appliances,
portable equipment, etc., with smaller transient overvoltages
than those characteristic of Overvoltage Category III. This
category applies from the wall plug to the power-supply iso-
lation barrier (transformer). The typical plant environment
is Overvoltage Category II, so most equipment evaluated to
the requirements of IEC/EN 61010 are considered to
belong in that classification.
3.0 Mean Time To Repair (MTTR)
SIL determinations are based on a number of factors includ-
ing the Mean Time To Repair (MTTR). The analysis for the
PULSAR Model R96 is based on a MTTR of 24 hours.
4.0 Supplementary Documentation
The PULSAR Model R96 Installation and Operating
Manual Bulletin 58-602 must be available for installation of
the measuring system.
One of the following Electronic Device Description Files is
also required if HART is used:
Manufacturer Code 0x56
Model R96 1.x Device ID 0x56DE, device revision 1,
DD revision 1.
For device installations in a classified area, the relevant safety
instructions and electrical codes must be followed.
5.0 Instructions
5.1 Systematic Limitations
The following must be observed to avoid systematic failures.
5.1.1 Application
Choosing the proper Pulse Burst Radar antenna is the most
important decision in the application process. The antenna
configuration establishes fundamental performance charac-
teristics. Horn and dielectric rod are the two basic configura-
tions. The antenna for use with the PULSAR Model R96
should be selected as appropriate for the application.
