1.0 Introduction
1.1 Product Description
The Pulsar®Model R96 Pulse Burst Radar Level
Transmitter is a loop-powered 24 VDC level transmitter
based on Pulse Burst Radar technology. For Safety
Instrumented Systems usage it is assumed that the 4–20 mA
output is used as the primary safety variable. The analog
output meets NAMUR NE 43 (3.8 mA to 20.5 mA
usable). The transmitter contains self-diagnostics and is pro-
grammed to send its output to a user-selected failure state
either low or high upon internal detection of a failure. The
device can be equipped with or without an LCD display.
Table 1 lists the versions of the PULSAR Model R96 that
have been considered for the hardware assessment.
1.2 Theory of Oper tion
PULSAR Model R96 is a top-mounted downward-looking
pulse burst radar operating at 6 GHz. Unlike true pulse
devices that transmit a single sharp (fast rise-time) waveform
of wide-band energy PULSAR Model R96 emits short bursts
of 6 GHz energy and measures the transit time of the signal
reflected off the liquid surface. Distance is calculated utiliz-
ing the equation: Distance = C ×Transit time/2 then devel-
oping the Level value by factoring in application-specific
configuration.
The PULSAR Model R96 is classified as a Type B device
according to IEC 61508.
1.3 Determining S fety Integrity Level (SIL)
Tables 2 & 3 define the criteria for the achievable SIL
against the target mode of operation in Demand Mode
Operation.
Table 2 shows the relationship between the Safety Integrity
Level (SIL) and the Probability of Failure on Demand
Average (PFDavg).
Table 3 can be used to determine the achievable SIL as a
function of the Hardware Fault Tolerance (HFT) and the
Safe Failure Fraction (SFF) for the complete safety system
(type B – complex components as per IEC 61508 Part 2) of
which the level transmitter is one component.

2.0 Level Me suring System
The diagram shows the structure of a typical measuring
system incorporating the MAGNETROL PULSAR Model
R96 Pulse Burst radar transmitter.
This SIL rated device is only available with an analog signal
(4–20 mA) with HART communications. The measure-
ment signal used by the logic solver must be the analog 4–
20 mA signal proportional to the level generated.
For fault monitoring the logic unit must recognize both
high alarms (≥21.5 mA) and low alarms (≤3.6 mA). If the
logic solver loop uses intrinsic safety barriers caution must
be taken to ensure the loop continues to operate properly
under the low alarm condition.
The only unsafe mode is when the unit is reading an incor-
rect level within the 4-20mA range (> ±2% deviation).
MAGNETROL defines a safe failure as one in which the
4-20 mA current is driven out of range (i.e. less than 3.8
mA or greater than 20.5 mA).
2.0.1 FOU DATIO fieldbus™
Although the PULSAR Model R96 is available with
FOUNDATION fieldbus™output it does not presently meet
the FF-SIS standard.
2.1 Applic ble Models
This manual is only applicable to the following PULSAR
Pulse Burst Radar Transmitter:
R96-511x-xxx (SIL 2 HFT 0)
2.2 Miscell neous Electric l Consider tions
Following are miscellaneous electrical issues to be considered.
2.2.1 Pollution Degree 2
The PULSAR system is designed for use in Category II
Pollution Degree 2 installations.
A nonconductive pollution of the sort where occasionally a
temporary conductivity caused by condensation must be
expected. This is the usual pollution degree used for equip-
ment being evaluated to IEC/EN 61010.

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 Me n Time To Rep ir (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 Supplement ry Document tion
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.

6.0 Recurrent Function Tests
6.1 Proof Testing
6.1.1 Introduction
Following are the procedures utilized to detect
Dangerous Undetected (DU) failures. The procedure
will detect approximately 98.1% of possible DU failures
in the Model R96-511*-***.
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). The SIL for the Model R96 is based
on the assumption that the operator will carry out these
tests and inspection at least once (1x) per year. The onus is
on the owner/operator to select the type of inspection and
the time period for these tests.
The system check must be carried out to prove that the
functions meet the IEC specification and result in the
desired response of the safety system as a whole.
This system check can be guaranteed when the response
height is approached in the filling process; though if this is
not practical a suitable method of simulating the level of
the physical measurement must be used to make the level
sensor respond as if the fill fluid were above the alarm/set
point level. If the operability of the sensor/transmitter can
be determined by other means that exclude all fault condi-
tions that may impair the normal functions of the device
the check may also be completed by simulating the corre-
sponding output signal of the device.
6.1.3 Recording results
Results of the Proof Test should be recorded for future
reference.

6.1.4 Proof Test Procedure
A suggested proof test is described below. This test will
detect approximately 85% of possible DU failures in
Model R96-511*-*** of the PULSAR Model R96 Pulse
Burst Radar Level Transmitter.
1. Bypass the safety PLC or take other appropriate action to
avoid a false trip.
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 tests for compliance voltage problems such as low
power supply voltage or increased loop wiring resistance.
This also tests for other possible failures in the current
loop circuitry.
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 tests for possible quiescent current related failures.
4. Reduce the level in the vessel. The Status parameter should
say “OK” and the level reading should be equal to the value
in the “Bottom Blocking Distance” parameter.
5. Perform a two-point calibration check of the transmitter by
applying level at two points and compare the transmitter
display reading and the current level value to a known refer-
ence measurement.
6. If the calibration is correct the proof test is complete.
Proceed to step 11.
7. If calibration is incorrect remove the transmitter and antenna
from the process. Inspect the antenna for buildup or clog-
ging. Clean the antenna if necessary.
Perform a bench verification by aiming the antenna at two
different distances from a target (such as a wall). First set
the device to measure Distance. Then compare the trans-
mitter display and loop current readings to the actual dis-
tances.
8. If the calibration is off by more than 2% call the factory for
assistance.
9. If the calibration is correct the proof test is complete.
Return the transmitter to level mode. Proceed to step 10.
10. Re-install the transmitter and antenna.
11. Restore the loop to full operation.
12. Remove the bypass from the safety PLC or otherwise restore
normal operation.
