Introduction
1.1
Product Description
The ECLIPSE Model 706 High Performance Guided Wave
Radar Level Transmitter is a loop-powered, 24 VDC level
transmitter, based on Guided Wave Radar (GWR) technology.
Table 1
ECLIPSE 706 Model Number
NOTE: For Safety Instrumented Systems usage, it is assumed that the
4–20 mA output is used as the primary safety variable.
Model 706-511x-xxx (HART)
The analog output from the Model 706 meets the NAMUR
NE 43 standard (3.8 mA to 20.5 mA usable). The transmitter
contains self-diagnostics and is programmed to drive the
output to a user-selected failure state, either low or high,
upon internal detection of a diagnostic indicator. The device
can be equipped with or without a graphic liquid crystal
display (LCD).
Table 1 indicates the version of the ECLIPSE Model 706
transmitter suitable for SIL 2 applications based on the
hardware assessment.
1.2
Guided Wave Radar is based upon the principle of TDR
(Time Domain Reflectometry). TDR utilizes pulses of electromagnetic energy transmitted down a wave guide (probe).
When a pulse reaches a liquid surface that has a higher
dielectric constant than the air (εr = 1) in which it is traveling,
a portion of the pulse is reflected. The transit time of the
pulse is then measured via ultra high-speed timing circuitry
that provides an accurate measure of the liquid level. The
amplitude of the reflection depends on the dielectric constant of the product. The higher the dielectric constant, the
larger the reflection.

3.1
The diagram at left shows the structure of a typical measuring
system incorporating the ECLIPSE Model 706 transmitter.
This SIL-rated device is only available with an analog signal
(4–20 mA) with HART communications; and, the measurement 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
incorrect level within the 4–20 mA 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 21.5 mA).
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.
This is the usual pollution degree used for equipment being
evaluated to IEC/EN 61010.
3.1.2 Over-voltage
The ECLIPSE Model 706 transmitter has, as standard, overvoltage protection per CE requirements. When considering
Hi-pot, Fast Transients and Surge, this protection is to 1000
volts (1 KV). Therefore, there should be no unsafe failure
modes up to 1 KV.
4
57-656 SIL Safety Manual for ECLIPSE Model 706
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
isolation barrier (transformer).
As the typical plant environment is Overvoltage Category II,
most equipment evaluated to the requirements of IEC/EN
61010 are considered to belong in that classification.
4.0
Mean Time To Restoration (MTTR)
SIL determinations are based on a number of factors including
the Mean Time To Restoration (MTTR). The analysis for
the ECLIPSE Model 706 is based on a MTTR of 24 hours.
5.0
Supplementary Documentation
• The ECLIPSE Model 706 Installation and Operating
Manual 57-606 must be available to ensure proper
installation of the transmitter.
• One of the following Electronic Device Description Files is
also required if HART is used:
• Manufacturer Code 0x56
• Model 706 Device ID 0x56E0, device revision 1,

General Instructions
6.1
Systematic Limitations
The following instructions must be observed to avoid
systematic failures.
6.1.1 Application
Choosing the proper Guided Wave Radar (GWR) probe is
the most important decision in the application process.
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.
Careful selection of probe design and materials for a specific
application will minimize media buildup on the probe.
Refer to Installation and Operating Manual 57-606 for

Configuration
6.5.1 General
The ECLIPSE Model 706 Transmitter can be configured via
the local display, a HART compatible handheld terminal, or
a personal computer using PACTware™ and the associated
DTM.
6.5.2 Configuration
Ensure the parameters have been properly configured for
the application and probe. Special consideration should be
given to the following configuration parameters:
DIELECTRIC: Ensure this is set to “Below 1.7” for
propane and butane applications or “1.7–3.0” for the
majority of typical hydrocarbon applications.
FAULT: DO NOT choose HOLD for this parameter as a
Fault will not be annunciated on the current loop.
BLOCKING DISTANCE: This value MUST be Zero for
SIL applications. Consult factory prior to making any
changes.
LOOP CONTROL MODE: Ensure this is set to ENABLED.
THRESHOLD: Set to FIXED if used in a hydrocarbon
application with any possibility of water bottoms.
PASSWORD: Must be changed to a specific value other
than Zero.
6.5.3 Write Protecting / Locking
The Model 706 transmitter is password protected with a
numerical password between 0 and 99,999.
NOTE: Default Password = 0 = Password disabled.
Refer to the Model 706 Installation and Operating Manual
Bulletin 57-606 for additional information on password
protection.
It is required that, after configuration of the system is complete, a password is utilized to prevent inadvertent changes
to the device.

Proof Testing
7.1.1 Introduction
Following is the procedure utilized to detect Dangerous
Undetected (DU) failures.
This procedure will detect approximately 84% of possible
DU failures in the Model 706-511x-xxx.
7.1.2 Interval
To maintain the appropriate Safety Integrity Level of a
Safety Instrumented System, it is imperative that the entire
system be tested at regular time intervals (shown as TI in the
appropriate standards). The suitable SIL for the Model 706
transmitter is based on the assumption that the end user
will carry out this test and inspection at least once per year.
NOTE: It is the responsibility of the owner/operator to select the type
of inspection and the time period for these tests.

Step
Action
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 integrity of the housing and the environmental protection, the unit should be repaired
or replaced.
b.) Inspect the interior of the Unit. Any evidence of moisture, from process or environment, is an
indication of housing damage, and the unit should be repaired or replaced.
3
Use the Unit’s DIAGNOSTICS menu to observe Present Status, and review EVENT HISTORY in the
Event Log. Up to 10 events are stored. The events will be date and time stamped if the internal clock is
set and running. It is suggested that the internal clock be set at the time of commissioning of the unit.
If the clock is set at the time of the proof test, event times are calculated.
a.) Choose the menu DIAGNOSTICS / Present Status.
i.) Present Status should indicate OK.
b.) Choose the menu DIAGNOSITICS / EVENT HISTORY/ Event Log
i.) Any FAULT or WARNING messages must be investigated and understood.
ii.) Corrective actions should be taken for FAULT messages.
4
Use the DIAGNOSTICS menu to perform a “CURRENT LOOP TEST”. 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.
i.) This step tests for compliance voltage problems such as low supply voltage or increased
wiring resistance.
ii.) This also tests for current loop control circuitry and adjustment problems.
b.) Send a HART command to the transmitter (or use the local interface) to go to the low alarm
current output, 3.6 mA, and verify that the analog current reaches the valve.
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 output returns to its original state—with the
proper loop current as indicated and controlled by the unit.

Use the DIAGNOSITICS menu to observe the present Echo Curve. Confirm that the ECHO Waveform is
normal. The echo curve is dependent on the type of probe, the installation conditions and the level of
process on the probe. Comparison of the present Echo Curve to the one stored at the time of commissioning the unit gives additional confidence of the normal operation of the unit. Use of the DTM and
digital communications is necessary for comparison of echo curves.
a.) Select DIAGNOSTICS/ ECHO CURVE/ View Echo Curve
i.) Observe the present Echo Curve, identify the characteristic portions of the waveform related
to the FIDUCIAL, Process level, End of Probe and other features.
ii.) Confirm that the FIDUCIAL appears acceptable. Confirm the FIDUCIAL is located where
expected.
iii.) Confirm that the signal from the process level appears normal and is located as expected.
iv.) Verify that the baseline of the waveform is smooth and flat.
v.) Compare to Echo Curve from commissioning in the FIDUCIAL area.
b.) Access the Fiducial Ticks and Fiducial Strength values in the menu: DIAGNOSTICS /
ADVANCES DIAGNOSTICS / INTERNAL VALUES
i.) Observe and record:
1.) Fiducial Ticks _____________
2.) Fiducial Strength _____________
ii.) Confirm that these values match the previous values.
1.) Fiducial Ticks differs within ±100
2.) Fiducial Strength differs within ±15
6
Perform two-point calibration check of the transmitter by applying level to two points on the probe and
compare the transmitter display reading and the current level value to a known reference measurement.
7
If the calibration is correct the proof test is complete. Proceed to step 9.
8
If the calibration is incorrect, remove the transmitter and probe from the process. Inspect the probe for
buildup or clogging. Clean the probe, if necessary. Perform a bench calibration check by shorting the
probe at two points. Measure the level from the bottom of the probe to the two points and compare to
the transmitter display and current level readings.
a.) If the calibration is off by more than 2%, contact the factory for assistance.
b.) If the calibration is correct, the proof test in complete.
c.) Re-install the probe and transmitter.

PFDAVG value for a single, Model 706-511x-xxx
with proof test intervals of one year.
It is the responsibility of the Safety Instrumented Function
designer to perform calculations for the entire SIF. exida
recommends the accurate Markov-based exSILentia tool for
this purpose.
For SIL 2 applications, the PFDAVG value needs to be ≥ 10-3
and < 10-2. This means that for a SIL 2 application, the
PFDAVG for a 1-year Proof Test Interval of the Model
706-511x-xxx is approximately equal to 6.7% of the range.
These results must be considered in combination with
PFDAVG values of other devices of a Safety Instrumented
Function (SIF) in order to determine suitability for a specific
Safety Integrity Level (SIL).

8.5
Report: Lifetime of Critical Components
According to section 7.4.9.5 of IEC 61508-2, a useful lifetime, based on experience, should be assumed.
Although a constant failure rate is assumed by probabilistic
estimation method, this only applies provided that the useful lifetime of components is not exceeded. Beyond their
useful lifetime the result of the probabilistic calculation
method is therefore meaningless, as the probability of failure significantly increases with time. The useful lifetime is
highly dependent on the subsystem itself and its operating
conditions.
The assumption of a constant failure rate is based on the
bathtub curve. Therefore it is obvious that the PFDAVG calculation is only valid for components that have this constant domain and that the validity of the calculation is limited to the useful lifetime of each component.
The expected useful life of ECLIPSE Model 706-511x-xxx
is at least 50 years.
It is the responsibility of the end user to maintain and operate the Model 706-511x-xxx per manufacturer’s instructions. Furthermore, regular inspection should indicate that
all components are clean and free from damage.
When plant experience indicates a shorter lifetime than
indicated here, the number based on plant experience
should be used.
