The instructions in this manual assume that users are already familiar with ProLink II software. For
more information on using ProLink II, or for detailed instructions on installing ProLink II, see the
ProLink II software manual, which is available on the Micro Motion web site
(www.micromotion.com).
®
Windows-based configuration and management tool for
Using DisplayUsing HART CommunicatorUsing ProLink IIBefore You Begin
Note: ProLink II uses the Model 1500/1700/2500/2700 device descriptions for the LF-Series
field-mount transmitters. Accordingly, when you connect to an LF-Series transmitter, you will see a
Model 1500/1700/2500/2700 model code on the ProLink II screen.
3.2Requirements
To use ProLink II with an LF-Series transmitter, the following are required:
•ProLink II v2.0 or later (some LF models require later versions of ProLink II)
•Signal converter, to convert the PC’s serial port signal to the signal used by the transmitter
-For RS-485 connections, an RS-485 to RS-232 signal converter. The Black Box
RS-232 <-> 2-wire RS-485 Interface Converter (Code IC521A-F) signal converter is
available from Micro Motion. Contact Micro Motion if you need an RS-485 signal
converter.

3.4Connecting from a PC to an LF-Series field-mount transmitter
Depending on your transmitter, there are several options for connecting ProLink II to your transmitter.
See Table 3-1.
Note: Service port connections use standard settings, do not require transmitter configuration, and
are always available. Therefore, they are easy and convenient. However, service port connections
require opening the power supply compartment. Accordingly, service port connections should be used
only for temporary connections, and may require extra safety precautions.
Note: Due to the design of HART protocol, connections made using HART protocol are slower than
connections that use Modbus protocol. If you use HART protocol, you cannot open more than one
ProLink II window at a time.

for HART communication, see the transmitter installation manual for wiring
diagrams.
4.3.1Connecting to communication terminals
To connect the Communicator directly to the transmitter’s mA/HART terminals:
Connecting a HART device to the transmitter’s primary mA output terminals could cause transmitter
output error. Set control devices for manual operation before connecting a HART interface to the
transmitter’s primary mA output loop.
1. If you are connecting to an LF-Series field-mount transmitter, open the cover to the wiring
compartment.
22Micro Motion® LF-Series Transmitters
Opening the wiring compartment in a hazardous area can cause an explosion. When the transmitter is
in an explosive atmosphere, do not use the mA terminals to connect to your transmitter.
2. Connect the Communicator leads to the transmitter’s primary mA output terminals:
•FM transmitters: terminals 1 and 2 (see Figure 4-1)
•DIN transmitters: terminals 21 and 22 (see Figure 4-2)

5.1Overview
This chapter describes the procedures you should perform the first time you start the flowmeter. You
do not need to use these procedures every time you cycle power to the flowmeter.
The following procedures are discussed:
•Applying power to the flowmeter (see Section 5.2)
•Zeroing the flowmeter (see Section 5.5)
•Performing a loop test on the transmitter outputs (see Section 5.3)
•Trimming the mA outputs (see Section 5.4)
Figure 5-1 provides an overview of the flowmeter startup procedures.
Note: All ProLink II procedures provided in this chapter assume that your computer is already
connected to the transmitter and you have established communication. All ProLink II procedures also
assume that you are complying with all applicable safety requirements. See Chapter 3 for more
information.
Note: If you are using AMS, the AMS interface will be similar to the ProLink II interface described in
this chapter.
Note: All Communicator procedures provided in this chapter assume that you are starting from the
“Online” menu. See Chapter 4 for more information.
Configuration and Use Manual25
Flowmeter Startup
5.2Applying power
Before you apply power to the flowmeter, close and tighten all housing covers.
Operating the flowmeter without covers in place creates electrical hazards that can cause death, injury,
or property damage. Make sure safety barrier partition and covers for the field-wiring, circuit board
compartments, electronics module, and housing are all in place before applying power to the
transmitter.
Using the service port to communicate with an LF-Series field-mount transmitter in a hazardous area
can cause an explosion. Before using the service port to communicate with the transmitter in a
hazardous area, make sure the atmosphere is free of explosive gases.
Turn on the electrical power at the power supply. The flowmeter will automatically perform
diagnostic routines. When the flowmeter has completed its power-up sequence:
•For LF-Series field-mount transmitters under normal conditions, the status LED on the display
will turn green and begin to flash,
•For LF-Series DIN rail mount transmitters under normal conditions, the status LED will turn
green.
•If the status LED exhibits different behavior, an alarm condition is present or transmitter zero
is in progress. See Section 7.4.
5.2.1Communication methods after power-up
For LF-Series field-mount transmitters, all communication methods supported by the transmitter are
available immediately after power-up.
For LF-Series DIN rail mount transmitters:
•If you are using the Communicator, or ProLink II with HART protocol (HART/Bell202), you
can establish communication with the transmitter immediately after power-up, using terminals
21 and 22. See Chapter 4 for more information on using the Communicator, or Chapter 3 for
more information on using ProLink II.
•If you are using ProLink II via the RS-485 physical layer, terminals 33 and 34 are available in
service port mode for 10 seconds immediately after power-up. If no connection is made during
this period, the terminals are automatically reset to the configured Modbus communication
parameters. Be sure to set the ProLink II connection parameters appropriately. See Chapter 3.
5.3Performing a loop test
A loop test is a means to:
•Verify that analog outputs (mA and frequency) are being sent by the transmitter and received
accurately by the receiving devices
•Determine whether or not you need to trim the mA outputs
•Select and verify the discrete output voltage
•Read the discrete input
Perform a loop test on all inputs and outputs available on your transmitter. Before performing the loop
tests, ensure that your transmitter terminals are configured for the input/outputs that will be used in
your application (see Section 6.2).
You can perform a loop test with the display, with ProLink II, or the Communicator.

•When the output is unfixed:
-The dots disappear.
-The status LED returns to the state it was in before the output was fixed.
See Figure 5-4 for the loop test procedure. Not all options are available on all
transmitters.
Note the following:
•If you are testing the primary mA output, the HART/Bell202 signal to the
Communicator will affect the reading. Disconnect the Communicator before
reading the output, then reconnect the Communicator and resume the loop
test after taking the reading.
•The mA reading does not need to be exact. You will correct differences
when you trim the mA output. See Section 5.4.

5.4Trimming the milliamp outputs
Trimming the mA output creates a common measurement range between the transmitter and the device
that receives the mA output. For example, a transmitter might send a 4 mA signal that the receiving
device reports incorrectly as 3.8 mA. If the transmitter output is trimmed correctly, it will send a
signal appropriately compensated to ensure that the receiving device actually indicates a 4 mA signal.
You must trim the mA output at both the 4 mA and 20 mA points to ensure appropriate compensation
across the entire output range.
Perform a milliamp trim on all mA outputs available on your transmitter. Before performing the trim,
ensure that your transmitter terminals are configured for the input/outputs that will be used in your
application (see Section 6.2).
You can trim the outputs with ProLink II or a Communicator.
5.4.1Milliamp output trim with ProLink II
See Figure 5-5 for the mA output trim procedure.
Note the following:
•If you are trimming the primary mA output, and you are connected to the
transmitter via HART/Bell202, the HART/Bell202 signal to ProLink II will
affect the reading. Disconnect ProLink II before reading the output, then
reconnect and resume the trim, after taking the reading. If you are using any
other protocol, this is not required.
•Any trimming performed on the output should not exceed ± 200 microamps.
If more trimming is required, contact Micro Motion customer support.
•If you are trimming the primary mA output, the HART/Bell202 signal to the
Communicator will affect the reading. Disconnect the Communicator before
reading the output, then reconnect and resume the trim, after taking the
reading.
•Any trimming performed on the output should not exceed ± 200 microamps.
If more trimming is required, contact Micro Motion customer support.
•The receiving device value that you enter in the Communicator can contain
up to two decimal places.
Zeroing the flowmeter establishes the flowmeter’s point of reference when there is no flow.
When you zero the flowmeter, you may need to adjust the zero time parameter. Zero time is the
amount of time the transmitter takes to determine its zero-flow reference point. The default zero time
is 20 seconds.
•A long zero time may produce a more accurate zero reference but is more likely to result in a
zero failure. This is due to the increased possibility of noisy flow, which causes incorrect
calibration.
•A short zero time is less likely to result in a zero failure but may produce a less accurate zero
reference.
For most applications, the default zero time is appropriate.
Note: In some menus, a convergence limit parameter is displayed. Micro Motion recommends that you
use the default value for convergence limit.
Note: Do not zero the flowmeter if a high severity alarm is active. Correct the problem, then zero the
flowmeter. You may zero the flowmeter if a low severity alarm is active. See Section 7.4 for
information on viewing transmitter status and alarms.
You can zero the flowmeter with the display (if the transmitter has a display), ProLink II, the
Communicator, or with the Zero button on the transmitter (DIN rail mount transmitters only).
If the zero procedure fails, see Section 11.6 for troubleshooting information.
5.5.1Preparing for zero
To prepare for the zero procedure:
1. Apply power to the flowmeter. Allow the flowmeter to warm up for approximately 20 minutes.
2. Run the process fluid through the sensor until the sensor temperature reaches the normal
process operating temperature.
3. Close the shutoff valve downstream from the sensor.
4. Ensure that the sensor is completely filled with fluid.
5. Ensure that the process flow has completely stopped.
If fluid is flowing through the sensor, the sensor zero calibration may be inaccurate, resulting in
inaccurate process measurement. To improve the sensor zero calibration and measurement accuracy,
ensure that process flow through the sensor has completely stopped.

6.1Overview
This chapter describes the configuration procedures that are usually required when a transmitter is
installed for the first time.
The following procedures are discussed:
•Configuring transmitter terminals (see Section 6.2)
•Configuring measurement units (see Section 6.3)
•Configuring the mA output(s) (see Section 6.4)
•Configuring the frequency output (see Section 6.5)
•Configuring the discrete output (see Section 6.6)
•Configuring the discrete input (see Section 6.6.1)
This chapter provides basic flowcharts for each procedure. For more detailed flowcharts, see the
flowcharts for your transmitter and communication tool, provided in the appendices to this manual.
Default values and ranges for the parameters described in this chapter are provided in Appendix A.
For optional transmitter configuration parameters and procedures, see Chapter 8.
Note: All ProLink II procedures provided in this chapter assume that your computer is already
connected to the transmitter and you have established communication. All ProLink II procedures also
assume that you are complying with all applicable safety requirements. See Chapter 3 for more
information.
Note: If you are using AMS, the AMS interface will be similar to the ProLink II interface described in
this chapter.
Note: All Communicator procedures provided in this chapter assume that you are starting from the
“Online” menu. See Chapter 4 for more information.
6.2Configuring transmitter terminals
Configuration of the transmitter terminals has consequences for many following
configuration options. Therefore, it is important to configure or verify terminal
configuration at the beginning of transmitter configuration.
•If you have an FM CIO or DIN CIO transmitter, you must configure the
channels. Refer to Section 6.2.1.
•If you have a DIN CIO FD transmitter, you must configure the channels to
specific values. Refer to Section 6.2.2.
•If you have an FM AN M transmitter, you must specify whether terminals
3 and 4 will operate as a frequency output (FO) or a discrete output (DO).
Refer to Section 6.2.3.

6.4Configuring the mA output(s)
All transmitters have one mA output, called the primary mA output. Some
transmitters always have a secondary mA output, and some transmitters can be
configured for a secondary mA output (see Section 6.2, page 39). The menu options
for the secondary mA output will appear only if a secondary mA output is present
on your transmitter.
Note: Configure the transmitter for the required input/output types before configuring individual
outputs. See Section 6.2.
The following parameters must be set for the primary mA output, and for the secondary mA output if
it is present:
•Process variable
•Upper range value (URV) and lower range value (LRV)
•AO (analog output) cutoff
•Fault indicator and fault value
An additional parameter—added damping—can be configured if required.
To configure the mA outputs, see the menu flowcharts in Figure 6-4. For details on mA output
parameters, see Sections 6.4.1 through 6.4.5.
Figure 6-5Configuring the mA output(s)
Note: If you use the display to configure the mA output, you can configure only the process variable
and the range. To configure other mA output parameters, use ProLink II or the Communicator.

6.4.1Configuring the process variable
You can configure the process variables to be reported through the mA outputs.
Table 6-8 lists the process variables that can be assigned to the primary and
secondary mA outputs.
Note: Some transmitters can measure only mass flow and volume flow. See
Table 6-3.
Table 6-8mA output process variable assignments
Process variableProLink II codeCommunicator codeDisplay code
Note: The process variable assigned to the primary mA output is always the PV (primary variable)
defined for HART communications. You can specify this process variable either by configuring the
primary mA output or by configuring the PV (see Section 8.15.6). If you change the process variable
assigned to the mA output, the PV assignment is changed automatically, and vice versa.
If your transmitter has a secondary mA output, the process variable assigned to it is always the SV
(secondary variable) defined for HART communications. You can specify this process variable either
by configuring the secondary mA output or by configuring the SV (see Section 8.15.6). If you change
the process variable assigned to the mA output, the SV assignment is changed automatically, and vice
versa.
If your transmitter does not have a secondary mA output, the SV assignment must be configured
directly (see Section 8.15.6), and the value of the SV must be queried through an RS-485 connection,
read through the Communicator, or reported through burst mode.
6.4.2Configuring the mA output range (LRV and URV)
The mA outputs use a range of 4 to 20 mA to represent the assigned process
variable. You must specify:
•The lower range value (LRV) – the value of the process variable that will be
indicated when the mA output produces 4 mA
•The upper range value (URV) – the value of the process variable that will be
indicated when the mA output produces 20 mA
Enter values in the measurement units that are configured for the assigned process variable (see
Section 6.3).
Configuration and Use Manual47
Note: The URV can be set below the LRV; for example, the URV can be set to 0 and the LRV can be
set to 100.

•FM CIO
•DIN AN

6.4.3Configuring the AO cutoff(s)
The AO (analog output) cutoff specifies the lowest mass flow or volume flow value
that will be reported through the mA output. Any mass flow or volume flow values
below the AO cutoff will be reported as zero.
AO cutoff can be configured only if the process variable assigned to the mA output
is mass flow or volume flow. If an mA output has been configured for a process
variable other than mass flow or volume flow, the AO cutoff menu option is not
displayed for that output.
Note: For most applications, the default AO cutoff is used. Contact Micro Motion customer support
before changing the AO cutoff.
Multiple cutoffs
Cutoffs can also be configured for the mass flow and volume flow process variables (see Section 8.5).
If mass flow or volume flow has been assigned to an mA output, a non-zero value is configured for
the flow cutoff, and the AO cutoff is also configured, the cutoff occurs at the highest setting, as shown
in the following examples.
Example
Example
Configuration:
•Primary mA output: Mass flow
•Frequency output: Mass flow
•AO cutoff for primary mA output: 10 g/sec
•Mass flow cutoff: 15 g/sec
As a result, if the mass flow rate drops below 15 g/sec, all outputs
representing mass flow will report zero flow.
Configuration:
•Primary mA output: Mass flow
•Frequency output: Mass flow
•AO cutoff for primary mA output: 15 g/sec
•Mass flow cutoff: 10 g/sec
As a result:
•If the mass flow rate drops below 15 g/sec but not below 10 g/sec:
•The primary mA output will report zero flow.
•The frequency output will report nonzero flow.
•If the mass flow rate drops below 10 g/sec, both outputs will report
zero flow.

6.4.4Configuring the fault indicator and fault value
If the transmitter encounters an internal fault condition, it will indicate the fault by
sending a preprogrammed output level to the receiving device. You can specify the
output level by configuring the fault indicator. Options are shown in Table 6-9.
Note: By default, the transmitter immediately reports a fault when a fault is
encountered. You can delay reporting faults by changing the fault timeout. See
Section 8.12.

Fault indicatorFault output value
Upscale21–24 mA (default: 22 mA)
Downscale1.0–3.6 mA (default: 2.0 mA)
Internal zeroThe value associated with 0 (zero) flow, as determined by URV and LRV values
NoneTracks data for the assigned process variable; no fault action
Setting the fault indicator to NONE may result in process error due to undetected fault conditions. To
avoid undetected fault conditions when the fault indicator is set to NONE, use some other mechanism
such as digital communication to monitor device status.
A damping value is a period of time, in seconds, over which the process variable
value will change to reflect 63% of the change in the actual process. Damping helps
the transmitter smooth out small, rapid measurement fluctuations:
•A high damping value makes the output appear to be smoother because the
output must change slowly.
•A low damping value makes the output appear to be more erratic because the
output changes more quickly.
The added damping parameter specifies damping that will be applied to the mA output. It affects the
measurement of the process variable assigned to the mA output, but does not affect the frequency or
digital outputs.
Note: For most applications, the default added damping value is used. Contact Micro Motion
customer support before changing the added damping parameter.
Multiple damping parameters
Damping can also be configured for the flow (mass and volume), density, and temperature process
variables (see Section 8.6). If one of these process variables has been assigned to an mA output, a
non-zero value is configured for its damping, and added damping is also configured for the mA
output, the effect of damping the process variable is calculated first, and the added damping

6.5Configuring the frequency output(s)
Different transmitters have different frequency output options. See Section 6.2 for
information on configuring your transmitter’s outputs.
Note: Configure the transmitter for the required input/output types before
configuring individual outputs. See Section 6.2.

damping value.
The frequency output generates two voltage levels:
•0 V
•A site-specific voltage, determined by the power supply, pull-up resistor, and load (see the
installation manual for your transmitter)
If your transmitter is configured for two frequency outputs (CIO transmitters only), the Channel C
signal is generated from the Channel B signal, with a user-specified phase shift. The signals are
electrically isolated but not independent. You cannot configure Channel B and Channel C
independently.
Note: Configuring both Channel B and Channel C as frequency outputs is used to enable dual pulse
or quadrature mode (see Section 6.5.5).
If a frequency output is present on your transmitter, the following parameters must be set:
•Process variable
•Output scale
•Pulse width
•Polarity
•Mode (CIO transmitters only, if two frequency outputs have been configured)
•Fault indicator
To configure the frequency output, see the menu flowcharts in Figure 6-4. For details on mA output
parameters, see Sections 6.5.1 through 6.5.5.
50Micro Motion® LF-Series Transmitters
Note: If you use the display to configure the frequency output, you can configure only the process
variable and the Frequency = flow output scale. To configure other frequency output parameters, use
ProLink II or the Communicator.
With a flow-only transmitter (FM AN A or DIN AN), the frequency output
assignment is controlled by the primary mA output assignment. If mass flow or
volume flow is assigned to the primary mA output, the same process variable is
assigned to the frequency output.
With a multivariable transmitter (FM AN M, FM CIO, or DIN CIO), the frequency
output is independent of the primary mA output. Table 6-10 lists the process
variables that can be assigned to the frequency output.

defined for HART communications. You can specify this process variable either by configuring the
frequency output or by configuring the TV (see Section 8.15.6). If you change the process variable
assigned to the mA output, the TV assignment is changed automatically, and vice versa.
If your transmitter does not have a frequency output, the TV assignment must be configured directly
(see Section 8.15.6), and the value of the TV must be queried through an RS-485 connection, read
through the Communicator, or reported through burst mode.

6.5.2Configuring the output scale
The frequency output scale defines the relationship between output pulse and flow
units. You can select one of three output scale methods, as listed in Table 6-11.
Table 6-11 Frequency output scale methods and required parameters
MethodDescriptionRequired parameters
Frequency = flow• Frequency calculated from flow rate as described
below
Pulses per unit• A user-specified number of pulses represents one
flow unit
Units per pulse• A pulse represents a user-specified number of flow
units
• TV frequency factor
• TV rate factor
• TV pulses/unit
• TV units/pulse
Frequency = flow
If you specify
rate factor
Frequency = flow, you must also specify TV frequency factor and TV rate factor. TV
is defined as the maximum flowrate appropriate to your application. TV frequency factor
can then be calculated using the following formula:
where:
•Rate = maximum appropriate flowrate (
TV rate factor in configuration)
•T = factor to convert selected flow time base to seconds
•N = number of pulses per flow unit, as configured in the receiving device
The resulting
TV frequency factor value must be within the range of the frequency output (0 to
10,000 Hz).
•If the
TV frequency factor value is less than 1 Hz, reconfigure the receiving device for a
higher pulses/unit setting.
•If the
TV frequency factor value is greater than 10,000 Hz, reconfigure the receiving device
Maximum appropriate flowrate (TV rate factor) is 2000 lbs/min.
Receiving device is configured for 10 pulses/pound.
Solution:
Configuration:
•TV frequency factor = 333.33
•TV rate factor = 2000
The frequency output maximum pulse width defines the maximum duration of each
pulse the transmitter sends to the frequency receiving device, as shown in
Figure 6-7.
The pulse width is configurable to values between 0 and 277 milliseconds.
As the frequency increases, at some point the pulse width will become equivalent to the desired output
frequency. This frequency is called the crossover frequency, and is calculated as follows:
Note: Although you can set maximum pulse width to 0, it is not useful because it will result in an
undefined crossover frequency.
At frequencies above the crossover frequency, the output changes to a 50% duty cycle as shown in
Figure 6-8.
Figure 6-850% duty cycle
Configuration and Use Manual53
Required Transmitter Configuration
•FM AN F
•FM AN M
•FM CIO
•DIN AN
•DIN CIO
The default pulse width is 277 milliseconds, which yields a crossover frequency of 1.8 Hz. In other
words, above 1.8 Hz, the transmitter’s frequency output will use a 50% duty cycle. At frequencies of
1.8 Hz or lower, the pulse width will be 277 ms. In both cases, the process variable is represented by
the number of pulses per unit of time.
The transmitter’s maximum crossover frequency is 922 Hz. This corresponds to a pulse width of
0.543 ms.
You can change the setting for maximum pulse width so that the transmitter will output a pulse width
appropriate to your receiving device:
•High-frequency counters such as frequency-to-voltage converters, frequency-to-current
converters, and Micro Motion peripherals usually require approximately a 50% duty cycle.
•Electromechanical counters and PLCs that have low-scan cycle rates generally use an input
with a fixed nonzero state duration and a varying zero state duration. Most low-frequency
counters have a specified requirement for the maximum pulse width.
Note: For typical applications, the default pulse width is used.
Example
Note: If you are using the Frequency = Flow output scale method, and you set maximum pulse width
to a value below 277 ms, Micro Motion recommends setting the frequency factor to a value below
200 Hz. See Section 6.5.2.
6.5.4Configuring the frequency output polarity
The frequency output is wired to a PLC with a specified pulse width
requirement of 50 ms. The crossover frequency is 10 Hz.
Solution:
•Set Max Pulse Width to 50 ms.
•For frequencies less than 10 Hz, the frequency output will have a
50 msec ON state, and the OFF state will be adjusted as required.
For frequencies higher than 10 Hz, the frequency output will be a
square wave with a 50% duty cycle.
The frequency output polarity controls how the output indicates the active (ON)
state. See Table 6-12. The default value, Active high, is appropriate for most
applications. Active low may be required by applications that use low-frequency
signals.

6.5.5Configuring mode
If both Channel B and Channel C are configured as frequency outputs, they function
as a dual pulse output. In dual pulse mode, the second frequency output can be
phase-shifted either 0°, 180°, +90°, or –90°, or set to Quadrature (the default). See
Figure 6-9.
In Quadrature mode, Channel C:
•Lags Channel B by 90° during forward flow.
•Leads Channel C by 90° during reverse flow.
•Is driven to zero during a fault condition.
Quadrature mode is used only for specific Weights & Measures applications where required by law.
Figure 6-9Dual pulse output options
Note: If only one channel is configured as a frequency output,
If the transmitter encounters an internal fault condition, it will indicate the fault by
sending a preprogrammed output level to the receiving device. You can specify the
output level by configuring the fault indicator. See Table 6-13.
Note: By default, the transmitter immediately reports a fault when a fault is
encountered. You can delay reporting faults by changing the fault timeout. See
Section 8.12.

NoneTracks the data for the assigned process variable; no fault action
Setting the fault indicator to NONE may result in process error due to undetected fault conditions. To
avoid undetected fault conditions when the fault indicator is set to NONE, use some other mechanism
such as digital communication to monitor device status.
6.6Configuring the discrete output(s)
Different transmitters have different discrete output (DO) options. See Section 6.2,
page 39, for information on configuring your transmitter’s outputs.
Note: Configure the transmitter for the required input/output types before
configuring individual outputs. See Section 6.2.
The discrete outputs generate two voltage levels to represent ON or OFF states. The voltage levels
depend on the output’s polarity, as shown in Table 6-14
. Figure 6-10shows a diagram of a typical
discrete output circuit.

Figure 6-11 Configuring the discrete output(s)
6.6.1Flow switch
Flow switch refers to the flow rate moving past a user-configured setpoint, in either direction. For
example, if the setpoint is 100 lb/min, a flow switch occurs if the flow rate changes from 101 lb/min
to 99 lb/min, or from 99 lb/min to 101 lb/min.
The flow switch has a 5% hysteresis. For example, if the setpoint is 100 lb/min, the flow switch will
be triggered when the flow rate falls below 100 lb/min, but not turned off until a 5% (5 lb/min) change
occurs (i.e., the flow rate rises to 105 lb/min).
If a discrete output is assigned to flow switch, the flow switch setpoint must be configured.
Note: If your transmitter is configured with two discrete outputs, it is possible to configure both DO1
and DO2 for flow switch, but it is not useful because you cannot configure independent setpoints.
6.7Configuring the discrete input
The discrete input is used to initiate a transmitter action from a remote input device.
If your transmitter has been configured for a discrete input, the actions listed in
Table 6-16 may be assigned to the discrete input.
Note: Configure the transmitter for the required input/output types before
configuring the discrete input. See Section 6.2.
To configure the discrete input, see the menu flowcharts in Figure 6-12.

This chapter describes how to use the transmitter in everyday operation. The following topics and
procedures are discussed:
•Viewing process variables (see Section 7.3)
•Viewing transmitter status and alarms (see Section 7.4)
•Acknowledging alarms (see Section 7.5)
•Viewing and using the totalizers and inventories (see Section 7.6)
Note: All ProLink II procedures provided in this section assume that your computer is already
connected to the transmitter and you have established communication. All ProLink II procedures also
assume that you are complying with all applicable safety requirements. See Chapter 3 for more
information.
Note: If you are using AMS, the AMS interface will be similar to the ProLink II interface described in
this chapter.
Note: All Communicator key sequences in this section assume that you are starting from the “Online”
menu. See Chapter 4 for more information.
7.2Recording process variables
Micro Motion suggests that you make a record of the process variables listed below, under normal
operating conditions. This will help you recognize when the process variables are unusually high or
low, and may help in fine-tuning transmitter configuration.
Record the following process variables:
•Flow rate
•Density
•Temperature
•Tube frequency
•Pickoff voltage
•Drive gain
For information on using this information in troubleshooting, see Section 11.12.
7.3Viewing process variables
Process variables include measurements such as mass flow rate, volume flow rate, mass total, volume
total, temperature, and density.
You can view process variables with the display (field-mount transmitters only), ProLink II, or the
Communicator.

7.4Viewing transmitter status and alarms
62Micro Motion® LF-Series Transmitters
You can view transmitter status using the status LED or display, ProLink II, or the Communicator.
The transmitter broadcasts alarms whenever a process variable exceeds its defined limits or the
transmitter detects a fault condition. You can view alarms with the display, ProLink II, or the
Communicator. For information regarding all the possible alarms, see Table 11-5.
To acknowledge alarms, you must use the display. Acknowledging alarms is required only for
transmitters that have a display.

7.4.2Using the display
The display reports alarms in two ways:
•With the status LED, which reports only that one or more alarms has
occurred
•Through the alarm queue, which reports each specific alarm
Note: If access to the alarm menu from the display has been disabled (see Section 8.14.1), then the
display will not list alarm codes in an alarm queue, and the status LED will not flash. It will indicate
status using solid green, yellow, or red.
For these transmitters, the status LED is located at the top of the display (see Figure 7-1). It can be in
one of six possible states, as listed in Table 7-1.

7.6Using the totalizers and inventories
The totalizers keep track of the total amount of mass or volume measured by the transmitter over a
period of time. The totalizers can be viewed, started, stopped, and reset.
The inventories track the same values as the totalizers but can be reset separately. Because the
inventories are reset separately, you can keep a running total of mass or volume across multiple
totalizer resets.

This chapter describes transmitter configuration parameters that may or may not be used, depending
on your application requirements. For required transmitter configuration, see Chapter 6.
8.2Configuration map
Different transmitters support different parameters and features. Additionally, different configuration
tools allow you to configure different features. Table 8-1 lists the optional configuration parameters.
For each parameter, the table also lists the transmitters that support that parameter and a reference to
the section where the parameter is discussed.
For the transmitter codes used in the configuration map, see Section 1.3.

If you need to use a non-standard unit of measure, you can create one special
measurement unit for mass flow and one special measurement unit for volume flow.
8.4.1About special measurement units
Special measurement units consist of:
•Base unit — A combination of:
-Base mass or base volume unit — A measurement unit that the transmitter already
recognizes (e.g., kg, m
3
)
-Base time unit — A unit of time that the transmitter already recognizes (e.g., seconds,
days)
•Conversion factor — The number by which the base unit will be divided to convert to the
special unit
•Special unit — A non-standard volume flow or mass flow unit of measure that you want to be
reported by the transmitter
The terms above are related by the following formula:
To create a special unit, you must:
1. Identify the simplest base volume or mass and base time units for your special mass flow or
volume flow unit. For example, to create the special volume flow unit pints per minute, the
simplest base units are gallons per minute:
•Base volume unit: gallon
•Base time unit: minute
2. Calculate the conversion factor using the formula below:
3. Name the new special mass flow or volume flow measurement unit and its corresponding
totalizer measurement unit:
•Special volume flow measurement unit name: Pint/min
•Volume totalizer measurement unit name: Pints
Note: Special measurement unit names can contain up to 8 characters, but only the first 5 characters
appear on the display.
4. To apply the special measurement unit to mass flow or volume flow measurement, select
Special from the list of measurement units (see Section 6.3.1 or 6.3.2).

Note: You cannot create a special mass flow measurement unit with the display, but you can view the
special mass flow measurement on the display.
8.4.3Special volume flow unit
To create a special mass flow measurement unit:
1. Specify the base mass unit.
2. Specify the base time unit.
3. Specify the mass flow conversion factor.
4. Assign a name to the new special mass flow measurement unit.
5. Assign a name to the mass totalizer measurement unit.
To create a special volume flow measurement unit:
1. Specify the base volume unit.
2. Specify the base time unit.
3. Specify the volume flow conversion factor.
4. Assign a name to the new special volume flow measurement unit.
5. Assign a name to the volume totalizer measurement unit.
Note: You cannot create a special volume flow measurement unit with the display, but you can view
the special volume flow measurement on the display.
8.4.4Special unit for gas
For many gas applications, standard or normal volume flow rate is used as the quasi
mass flow rate. Standard or normal volume flow rate is calculated as the mass flow
rate divided by the density of the gas at a reference condition.
To configure a mass flow special unit that represents standard or normal volume
flow rate, you must calculate the mass flow conversion factor from the density of the
gas at a reference temperature, pressure, and composition.
ProLink II offers a Gas Unit Configurator tool to calculate this mass flow conversion factor. The tool
will automatically update the mass flow conversion factor in the
Special Units tab. If ProLink II is
not available, special mass units can be used to set up standard or normal volume flow units for gas
applications.
Note: Micro Motion recommends that you do not use the flowmeter to measure actual volume flow of
a gas (volumetric flow at line conditions). If you need to measure actual volume flow, contact Micro
Motion customer support.
74Micro Motion® LF-Series Transmitters
The flowmeter should not be used for measuring the actual volume of gases. Standard or normal
volume is the traditional unit for gas flow. Coriolis flowmeters measure mass. Mass divided by standard
or normal density yields standard or normal volume units.

Cutoffs are user-defined values below which the transmitter reports a value of zero
for the specified process variable. Cutoffs can be set for mass flow, volume flow, or
density.
Note: The density cutoff is available only with sensor software 2.1 or above and
MVD software rev 3.0 or above.
See Table 8-2 for cutoff default values and related information. See Sections 8.5.1
and 8.5.2 for information on how the cutoffs interact with other transmitter
measurements.

8.5.1Cutoffs and volume flow
The mass flow cutoff is not applied to the volume flow calculation. Even if the mass flow drops below
the cutoff, and therefore the mass flow indicators go to zero, the volume flow rate will be calculated
from the actual mass flow process variable.
Optional Configuration
•FM AN F
•FM AN M
•FM CIO
•DIN AN
•DIN CIO
• DIN CIO FD
However, the density cutoff is applied to the volume flow calculation. Accordingly, if the density
drops below its configured cutoff value, both the density and the volume flow rate will go to zero.
8.5.2Interaction with the AO cutoffs
Both the primary mA output and the secondary mA output (if it is available on your transmitter) have
cutoffs (the AO cutoffs). If the mA outputs are configured for mass and volume flow:
•And the AO cutoffs are set to a greater value than the mass and volume cutoffs, the flow
indicators will go to zero when the AO cutoff is reached.
•And the AO cutoffs are set to a lower value than the mass or volume cutoff, the flow indicator
will go to zero when the mass or volume cutoff is reached.
See Section 6.4.3 for more information on the AO cutoff(s).
8.6Configuring the damping values
A damping value is a period of time, in seconds, over which the process variable
value will change to reflect 63% of the change in the actual process. Damping helps
the transmitter smooth out small, rapid measurement fluctuations.
•A high damping value makes the output appear to be smoother because the
output must change slowly.
•A low damping value makes the output appear to be more erratic because the
output changes more quickly.
When you specify a new damping value, it is automatically rounded down to the nearest valid
damping value. Flow, density, and temperature have different valid damping values. Valid damping
values are listed in Table 8-3.
Note: For gas applications, Micro Motion recommends a flow damping value of 3.2 or higher.
Before setting the damping values, review Sections 8.6.1 through 8.6.3 for information on how the
damping values interact with other transmitter measurements and parameters.
Table 8-3Valid damping values
Process variableUpdate rate
Flow (mass and volume)Normal0, .2, .4, .8, ... 51.2
When configuring damping values, be aware that volume measurement is derived from mass and
density measurements; therefore, any damping applied to mass flow and density will affect volume
measurements. Be sure to set damping values accordingly.

8.6.2Interaction with the added damping parameter
Both the primary mA output and the secondary mA output (if it is available on your transmitter) have
a damping parameter (added damping). If damping is configured for flow, density, or temperature, the
same process variable is assigned to an mA output, and added damping is also configured for the mA
output, the effect of damping the process variable is calculated first, and the added damping
calculation is applied to the result of that calculation.
See Section 6.4.5 for more information on the added damping parameter.
8.6.3Interaction with the update rate
Flow and density damping values depend on the configured update rate (see Section 8.7). If you
change the update rate, the damping values are automatically adjusted.
Note: The specific process variable selected for the Special update rate is not relevant; all damping
values are adjusted as described.
8.7Configuring the update rate
The update rate is the rate at which the sensor reports the process variables to the
transmitter. This affects transmitter response time to changes in the process.
There are two settings for the update rate: Normal and Special.
•When Normal is selected, all process variables are reported at the rate of 20
times per second (20 Hz).
•When Special is selected, a single, user-specified process variable is updated
at 100 times per second (100 Hz), and all other process variables are updated
at 6.25 times per second (6.25 Hz). If you set the update rate to Special, you
must also specify which process variable will be updated at 100 Hz.
Note: Most users should select the Normal update rate. Use the Special update rate only if required
by your application. Contact Micro Motion before setting the update rate to Special.
Note: If you change the update rate, the setting for damping is automatically adjusted. See
Section 8.6.3.
8.8Configuring the flow direction parameter
The flow direction parameter controls how the transmitter reports flow rate and how
flow is added to or subtracted from the totalizers, under conditions of forward flow,
reverse flow, or zero flow.
•Forward (positive) flow moves in the direction of the arrow on the sensor.
•Reverse (negative) flow moves in the direction opposite of the arrow on the
sensor.

Configuring an event includes the following steps:
1. Selecting event 1 or event 2.
2. Assigning a process variable to the event.
3. Specifying an alarm type:
•Active high – alarm is triggered if process variable goes above setpoint
•Active low – alarm is triggered if process variable goes below setpoint
4. Specifying the setpoint – the value at which the event will occur or switch state (ON to OFF, or
vice versa).
Note: Events do not occur if the process variable equals the setpoint. The process variable must be
greater than (Active high) or less than (Active low) the setpoint for the event to occur.
An event occurs if the real-time value of a user-specified process variable varies
beyond a user-specified value. Events are used to perform specific actions on the
applications platform. For example, the event can be defined to activate a discrete
output if the flow rate is above a specified value. The discrete output, then, may be
configured to close a valve.
You can define one or two events. You may define the events on a single process
variable or on two different process variables. Each event is associated with either a
high or a low alarm.

8.9.1Reporting event status
There are several ways that event status can be reported:
•If your transmitter has a discrete output, the discrete output can be configured to switch states
according to event status (see Section 6.6).
•Event status can be queried using digital communications:
-ProLink II automatically displays event information on the
Status window.
-The Communicator reports Alarm 108 (Event 1 On) or Alarm 109 (Event 2 On), and also
shows event status in
Process Variables/View Status.
8.10Configuring slug flow limits and duration
Slugs – gas in a liquid process or liquid in a gas process – occasionally appear in
some applications. The presence of slugs can significantly affect the process density
reading. The slug flow parameters can help the transmitter suppress extreme
changes in process variables, and can also be used to identify process conditions that
require correction.
Slug flow parameters are as follows:
•Low slug flow limit – the point below which a condition of slug flow will exist. Typically, this
is the lowest density point in your process’s normal density range. Default value is 0.0 g/cm
3
range is 0.0–10.0 g/cm
.
•High slug flow limit – the point above which a condition of slug flow will exist. Typically, this
is the highest density point in your process’s normal density range. Default value is 5.0 g/cm
range is 0.0–10.0 g/cm
3
.
Informational panel of the
3
;
3
;
•Slug flow duration – the number of seconds the transmitter waits for a slug flow condition
(outside the slug flow limits) to return to normal (inside the slug flow limits). If the transmitter
detects slug flow, it will post a slug flow alarm and hold its last “pre-slug flow” flow rate until
the end of the slug flow duration. If slugs are still present after the slug flow duration has
expired, the transmitter will report a flow rate of zero. Default value for slug flow duration is
0.0 seconds; range is 0.0–60.0 seconds.
Note: Raising the low slug flow limit or lowering the high slug flow limit will increase the possibility
of slug flow conditions.
Note: The slug flow limits must be entered in g/cm
density. Slug flow duration is entered in seconds.
8.11Configuring entrained air handling
Entrained air refers to bubbles of air or other gas in the process fluid. These are also known as slugs
(see Section 8.10). The terms “slug flow” and “two-phase flow” are used to refer to the situation in
which the proportion of slugs to process fluid is outside the defined limits. (See Section 8.10 for
information on defining the slug flow limits.)
By default, if slug flow occurs, alarms are posted, totalizers stop, and outputs go to the configured
fault output level. This means that no process measurement occurs during conditions of slug flow.
Entrained air handling is used to allow process measurement to continue during conditions of slug
flow.
•The fault indicator is set to None for the mA output and digital output (see Sections 6.4.4 and
8.15.1).
•Update rate is set to Special (see Section 8.7).
•Mass flow is specified as the 100 Hz variable (see Section 8.7).
The slug flow alarm is still posted.
8.12Configuring fault timeout
By default, the transmitter immediately reports a fault when a fault is encountered.
You can configure the transmitter to delay reporting a fault by changing the fault
timeout to a nonzero value. During the fault timeout period, the transmitter
continues to report its last valid measurement.
Note: Although some communication tools allow you to configure the fault timeout
in two locations, only one value is stored. If you change the fault timeout in one
location, the value displayed on the other location is changed.
Meter factors allow you to modify the transmitter’s output so that it matches an
external measurement standard. Meter factors are used for proving the flowmeter
against a Weights & Measures standard. You may need to calculate and configure
meter factors periodically to comply with regulations.
You can adjust meter factors for mass flow, volume flow, and density. Only values
between 0.8 and 1.2 may be entered. If the calculated meter factor exceeds these
limits, contact Micro Motion Customer Service.
8.13.1Calculating meter factors
Use the following formula to calculate a meter factor:
Example
The flowmeter is installed and proved for the first time. The flowmeter
mass measurement is 250.27 lb; the reference device measurement is
250 lb. A mass flow meter factor is determined as follows:
Configuration and Use Manual83
The first mass flow meter factor is 0.9989.
One year later, the flowmeter is proved again. The flowmeter mass
measurement is 250.07 lb; the reference device measurement is
250.25 lb. A new mass flow meter factor is determined as follows:
The new mass flow meter factor is 0.9996.

8.14.2Changing the scroll rate
The scroll rate is used to control the speed of scrolling when auto scroll is enabled. Scroll rate defines
how long each display variable (see Section 8.14.4) will be shown on the display. The time period is
defined in seconds; e.g., if scroll rate is set to 10, each display variable will be shown on the display
for 10 seconds.
If you are using the Communicator to configure the transmitter, you must enable auto scroll before
you can configure scroll rate (see Section 8.14.1).
8.14.3Changing the off-line password
The off-line password prevents unauthorized users from gaining access to the off-line menu.
The password can contain up to four numbers.
If you are using the Communicator, you must enable the off-line password before you can configure it
(see Section 8.14.1).
8.14.4Changing the display variables
The display can scroll through up to 15 process variables in any order. You can configure the process

8.15.2Changing the HART polling address
The transmitter’s HART polling address is used by devices on a network to identify
and communicate with the transmitter using HART protocol. The HART polling
address must be unique on the network. If the transmitter will not be accessed using
HART protocol, the HART polling address is not required.
The HART polling address is used for both HART/Bell202 and HART/RS-485
communications; i.e., for HART communication over either the primary mA output
terminals or the RS-485 terminals (AN transmitters only).
86Micro Motion® LF-Series Transmitters
Note: Devices using HART protocol to communicate with the transmitter may use either the HART
polling address or the HART tag (see Section 8.16) . You may configure either or both, as required by
your other HART devices.
Valid HART polling addresses are 0–15.
Zero is a special-purpose polling address that enables the primary mA output to vary according to the
assigned process variable. When a transmitter’s HART polling address is set to any value other than
zero, the primary mA output is fixed at 4 mA, and will not report any variation in the assigned process
variable.

8.15.3Changing the Modbus address
Note: If you are using ProLink II, and you are connected to the transmitter over a Modbus
connection, ProLink II will lose communication as soon as you click the Apply button. To reestablish
communication, you must change the communication settings specified in the ProLink II Connect
dialog box (see Chapter 3). This does not apply to service port connections.
8.15.4Changing the RS-485 parameters
The transmitter’s Modbus address is used by devices on a network to identify and
communicate with the transmitter using Modbus protocol. The Modbus address
must be unique on the network. If the transmitter will not be accessed using Modbus
protocol, the Modbus address is not required.
RS-485 parameters control how the transmitter will communicate over its RS-485
terminals. The RS-485 parameters are listed in Table 8-8.

To enable RS-485 communications with the transmitter from a remote device:
1. Set the transmitter’s digital communications parameters appropriately for your network.
2. Configure the remote device to use the specified parameters.
Note: Changing the RS-485 communication settings does not affect service port connections. Service
port connections always use default settings.

Note: In some versions of ProLink II, a button named Choose Typical HART Settings is provided.
When this button is pressed, the settings for the RS-485 terminals are changed to the most common
settings used for HART communications:
•Protocol: HART
•Parity: Odd
•Baud Rate: 1200
•Stop Bits: 1
Note the following when setting RS-485 parameters:
•If HART protocol is selected, setting the address to any number other than 0 automatically
fixes the mA output at 4 mA. To allow the mA output to vary with the assigned process
variable, this address must be set to 0.
•If you are using ProLink II, and you are connected to the transmitter over a Modbus RS-485
connection, ProLink II will lose communication as soon as you click the
reestablish communication, you must change the ProLink II communication settings to match
the settings configured in the transmitter.

-The address item allows users to enter the polling address. Valid addresses depend on the
protocol selected earlier. Valid addresses for Modbus protocol must be in one of the
following ranges: 1–15, 32–47, 64–79, or 96–110. Valid addresses for HART protocol
must be in the range 0–15. If Protocol is set to
NONE, the address item will not appear.
8.15.5Configuring HART burst mode
Burst mode is a specialized mode of communication during which the transmitter
regularly broadcasts HART digital information over the primary mA output. Burst
mode is ordinarily disabled, and should be enabled only if another device on the
network requires HART burst mode communication.
To configure burst mode:
1. Enable burst mode.
2. Specify the burst mode output. Options are described in Table 8-9.

8.15.6Configuring the PV, SV, TV, and QV assignments
In the transmitter, four variables are defined for HART communications: the PV
(primary variable), the SV (secondary variable), the TV (tertiary variable), and the
QV (quaternary variable). A process variable such as mass flow is assigned to each
HART variable.
The values of the assigned process variables can be reported or read in several ways:
•The PV is automatically reported through the primary mA output. It can also be queried via
digital communications or reported via burst mode. If you change the PV, the process variable
assigned to the primary mA output is changed automatically, and vice versa. See Section 6.4.1.
•The SV is automatically reported through the secondary mA output, if the transmitter has a
secondary mA output. It can also be queried via digital communications or reported via burst
mode. If you change the SV, the process variable assigned to the secondary mA output is
changed automatically, and vice versa. See Section 6.4.1.
•The TV is automatically reported through the frequency output, if the transmitter has a
frequency output. It can also be queried via digital communications or reported via burst
mode. If you change the TV, the process variable assigned to the frequency output is changed
automatically, and vice versa. See Section 6.5.1.
•The QV is not reported through an output. It can be queried via digital communications or
reported via burst mode.
Table 8-9 lists the valid process variable assignments for the PV, SV, TV, and QV on LF-Series
transmitters.
