3Using and Maintaining the Flowmeter
3.1Communications Tools
The following communications tools can be used to commission the transmitter:
•The appropriate version of the ProLink
•The 375 Field Communicator (handheld) with the appropriate HART device description (DD)
•AMS Device Manager
The proof test instructions in this manual are designed for use with ProLink II v2.8 or the HART
device rev 5, DD rev1. Adapt these instructions as required for use with earlier or later versions of
ProLink, the HART DD, or AMS Device Manager.
Refer to Micro Motion Series 1000 and Series 2000 Transmitters: Configuration and Use Manual for
information on connecting the handheld or ProLink II to the transmitter, and using the
communications tool with the transmitter.
3.2Installation and Commissioning
No special installation is required in addition to the standard installation practices outlined in
Micro Motion Model 1700 and Model 2700 Transmitters: Installation Manual and the appropriate
sensor installation manual.
During commissioning, the following safety-critical parameters must be verified or configured:
•Primary variable (process variable assigned to the primary mA output)
•Low flow cutoff
•Damping values (flow damping, density damping, temperature damping, added damping)
During the proof test, these parameters must be verified.
3.3Safety Integrity Parameter Settings
The following parameters need to be set in order to maintain the designed safety integrity:
ParameterReason
mA Fault Action
(set to Upscale or Downscale)
mA Fault LevelTo specify the actual mA output signal in case of fault:
Password option or write-protection
enabled
To specify if the mA output should go high (> 21 mA) or low
(< 3.6 mA) upon detection of an internal failure
• Upscale: range = 21–24 mA, default = 22 mA
• Downscale:
- I.S transmitters: range = 3.2–3.6 mA, default = 3.2 mA
- All other transmitters: range = 1.0–3.6 mA, default = 2.0 mA
To prevent accidental changes to parameter settings

3.4Proof Tests
The objective of proof testing is to detect failures within the Coriolis flowmeter with a Model 1700 or
Model 2700 transmitter that are not detected by the diagnostics of the transmitter. Of main concern
are undetected failures that prevent the Safety Instrumented Function from performing its intended
function.
The frequency of proof testing, or the proof test interval, is to be determined in reliability calculations
for the Safety Instrumented Functions for which the Coriolis flowmeter with a Model 1700 or
Model 2700 transmitter is applied. The proof tests must be performed at least as frequently as
specified in the calculation in order to maintain the required safety integrity of the Safety
Instrumented Function.
The person(s) performing the proof test of the Coriolis flowmeter with a Model 1700 or Model 2700
transmitter should be trained in SIS operations, including bypass procedures, flowmeter maintenance
and company Management of Change procedures. A handheld communicator or ProLink II is
required. Refer to Micro Motion Series 1000 and Series 2000 Transmitters: Configuration and Use Manual for information on connecting the handheld device or ProLink II to the transmitter, and using
the communications tool with the transmitter.
The results of the proof test need to be documented and this documentation should be part of a plant
safety management system. Any failures that are detected and that compromise functional safety
should be reported to the Product Safety Officer within Micro Motion (see Section 5).
Table 1-1 describes the proof test options and the associated DU (Dangerous Undetected) failure
detection rate.
The following proof test is recommended for all flowmeters.

Proof Test 2
The following proof test is recommended for all flowmeters with an enhanced core processor.
Note: Proof Test 2 incorporates all the steps of Proof Test 1.
StepAction
1Electronically bypass the safety PLC by using a maintenance override function or take other
appropriate action to avoid a false trip, following Management of Change procedures.
2Set each mA output to go to the Fault Level specified for Upscale, and verify that the mA
current reaches that value. If the mA output Fault Action is not set for Upscale, use the
default value (22 mA).
• Using a handheld:
• Using ProLink II: ProLink > Test > Fix mA Output
This tests for compliance voltage problems such as a low loop power supply voltage or
increased wiring resistance. This also tests for other possible failures.
3Set each mA output to go to the Fault Level specified for Downscale, and verify that the mA
current reaches that value. If the mA output Fault Action is not set for Downscale, use the
default value (I.S. transmitters: 3.2 mA, all other transmitters: 2.0 mA).
• Using a handheld:
• Using ProLink II: ProLink > Test > Fix mA Output
This tests for possible failures related to quiescent current.
4Read the temperature value from the sensor, compare it to process temperature, and verify
that this is a reasonable reading.

3.5Repair and Replacement
There are no user-replaceable components on printed circuit assemblies, and all other spare
components for the Model 1700 or Model 2700 transmitter must be purchased from Micro Motion.
Any failures that are detected and that compromise functional safety should be reported to the Product
Safety Officer within Micro Motion (see Section 5). When replacing the Coriolis sensor or the
Model 1700 or Model 2700 transmitter, the procedures in the applicable installation manual should be
followed. The user is responsible for maintaining adequate risk reduction for the Safety Instrumented
Function during repair and replacement.
3.6Firmware Update
In case firmware updates are required, they will be performed at the factory or by a Micro Motion
certified service technician. The user will not be required to perform any firmware updates.
4Operating Constraints
4.1Safety Accuracy
The Coriolis flowmeter with a Model 1700 or Model 2700 transmitter has a specified safety accuracy
of 2%. This means that internal component failures are listed in the device failure rate if they will
cause an error of 2% or greater.
4.2Diagnostic Response Time
The Coriolis flowmeter with a Model 1700 or Model 2700 transmitter will report an internal failure
within 5 minutes of fault occurrence (worst case).

4.3Startup Time
The Model 1700 or Model 2700 transmitter will generate a valid signal within 16 seconds of
power-on startup.
4.4Reliability Data and Lifetime Limit
A detailed Failure Mode, Effects, and Diagnostics Analysis (FMEDA) report is available from
Micro Motion. This report details all failure rates and failure modes, common cause factors for
applications with redundant devices and the expected lifetime of the Coriolis flowmeter with a
Model 1700 or Model 2700 transmitter.
The Coriolis flowmeter with a Model 1700 or Model 2700 transmitter is certified for applications up
to SIL2 for use in a simplex (1oo1) configuration, depending on the PFD
Safety Instrumented Function.
The development process of the Coriolis flowmeter with a Model 1700 or Model 2700 transmitter is
certified up to SIL3, allowing redundant use of the transmitter up to this Safety Integrity Level,
depending on the PFD
When using the Coriolis flowmeter with a Model 1700 or Model 2700 transmitter in a redundant
configuration, a common cause factor should be included in reliability calculations. For details, see
the FMEDA report.
The reliability data listed in the FMEDA report is valid only for the useful lifetime of the Coriolis
flowmeter with a Model 1700 or Model 2700 transmitter. The failure rates of the Coriolis flowmeter
with a Model 1700 or Model 2700 transmitter may increase sometime after this period. Reliability
calculations based on the data listed in the FMEDA report for mission times beyond the lifetime may
yield results that are too optimistic, i.e., the calculated Safety Integrity Level will not be achieved.
