Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks, or for process measurement.
1.
Ensure that all transmitter and sensor covers and seals are closed.
CAUTION!
To prevent ignition of flammable or combustible atmospheres, ensure that all covers and seals are tightly closed. For hazardous area installations, applying power while housing covers are removed or loose can cause an explosion.
2.
Turn on the electrical power at the power supply.
The transmitter will automatically perform diagnostic routines. During this period,
Alarm 009 is active. The diagnostic routines should complete in approximately
30 seconds. For transmitters with a display, the status LED will turn green and begin to flash when the startup diagnostics are complete. If the status LED exhibits different behavior, an alarm condition is present.
Postrequisites
Although the sensor is ready to receive process fluid shortly after power-up, the electronics can take up to 10 minutes to reach thermal equilibrium. Therefore, if this is the initial startup, or if power is been off long enough to allow components to reach ambient temperature, allow the electronics to warm up for approximately 10 minutes before relying on process measurements. During this warm-up period, you may observe minor measurement instability or inaccuracy.
Check flowmeter status
Check the flowmeter for any error conditions that require user action or that affect measurement accuracy.

Overview
Characterizing the flowmeter adjusts your transmitter to match the unique traits of the sensor it is paired with. The characterization parameters (also called calibration parameters) describe the sensor’s sensitivity to flow, density, and temperature.
Depending on your sensor type, different parameters are required. Values for your sensor are provided by Micro Motion on the sensor tag or the calibration certificate.
Tip
If your flowmeter was ordered as a unit, it has already been characterized at the factory. However, you should still verify the characterization parameters.
Procedure
1.
Specify Sensor Type.
•
Straight-tube
(T-Series)
•
Curved-tube
(all sensors except T-Series)
2.
Set the flow characterization parameters. Be sure to include all decimal points.
• For straight-tube sensors, set FCF (Flow Cal or Flow Calibration Factor), FTG, and FFQ.
• For curved-tube sensors, set Flow Cal (Flow Calibration Factor).
3.
Set the density characterization parameters.
• For straight-tube sensors, set D1, D2, DT, DTG, K1, K2, FD, DFQ1, and DFQ2.
• For curved-tube sensors, set D1, D2, TC, K1, K2, and FD. (TC is sometimes shown as DT.)
Sources and formats for characterization parameters
Different sensor tags display characterization parameters differently. On older sensors, the sensor tag may not contain all the required parameters.
Sample sensor tags
Sample sensor tags are shown in the following illustrations:

Density calibration parameters (D1, D2, K1, K2, FD, DT, TC)
If your sensor tag does not show a D1 or D2 value:
• For D1, enter the Dens A or D1 value from the calibration certificate. This value is the line-condition density of the low-density calibration fluid. Micro Motion uses air. If you cannot find a Dens A or D1 value, enter 0.001 g/cm
3
.
• For D2, enter the Dens B or D2 value from the calibration certificate. This value is the line-condition density of the high-density calibration fluid. Micro Motion uses water.
If you cannot find a Dens B or D2 value, enter 0.998 g/cm
3
.
If your sensor tag does not show a K1 or K2 value:
• For K1, enter the first 5 digits of the density calibration factor. In the sample tag, this value is shown as 12500 (see
• For K2, enter the second 5 digits of the density calibration factor. In the sample tag,
this value is shown as 14286 (see
).
If your sensor does not show an FD value, contact Micro Motion customer service.
Micro Motion ® Model 1700 Transmitters with Analog Outputs
2.5
Quick start
If your sensor tag does not show a DT or TC value, enter the last 3 digits of the density calibration factor. In the sample tag, this value is shown as 4.44 (see
Flow calibration parameters (FCF, FT)
Two separate values are used to describe flow calibration: a 6-character FCF value and a 4character FT value. Both values contain decimal points. During characterization, these may be entered as two values or as a single 10-character string. The 10-character string is called either Flowcal or FCF.
If your sensor tag shows the FCF and the FT values separately and you need to enter a single value, concatenate the two values to form the single parameter value.
If your sensor tag shows a concatenated Flowcal or FCF value and you need to enter the FCF and the FT values separately, split the concatenated value:
•
FCF
= The first 6 characters, including the decimal point
•
FT
= The last 4 characters, including the decimal point
Example: Concatenating FCF and FT
FCF = x.xxxx
FT = y.yy
Flow calibration parameter: x.xxxxy.yy
Example: Splitting the concatenated Flowcal or FCF value
Flow calibration parameter: x.xxxxy.yy
FCF = x.xxxx
FT = y.yy
Verify mass flow measurement
Check to see that the mass flow rate reported by the transmitter is accurate. You can use any available method.
• Read the value for Mass Flow Rate on the transmitter display.
• Connect to the transmitter with ProLink II and read the value for Mass Flow Rate in the
Process Variables window (ProLink > Process Variables).
• Connect to the transmitter with ProLink III and read the value for Mass Flow Rate in the Process Variables panel.
• Connect to the transmitter with the Field Communicator and read the value for Mass
Flow Rate in the Process Variables menu (On-Line Menu > Overview > Primary Purpose
Variables ).
Postrequisites
If the reported mass flow rate is not accurate:
• Check the characterization parameters.

• Review the troubleshooting suggestions for flow measurement issues. See
Verify the zero
Verifying the zero helps you determine if the stored zero value is appropriate to your installation, or if a field zero can improve measurement accuracy.
The zero verification procedure analyzes the Live Zero value under conditions of zero flow, and compares it to the Zero Stability range for the sensor. If the average Live Zero value is within a reasonable range, the zero value stored in the transmitter is valid. Performing a field calibration will not improve measurement accuracy.
Verify the zero using ProLink II
Verifying the zero helps you determine if the stored zero value is appropriate to your installation, or if a field zero can improve measurement accuracy.
•
•
Important
In most cases, the factory zero is more accurate than the field zero. Do not zero the flowmeter unless one of the following is true:
The zero is required by site procedures.
The stored zero value fails the zero verification procedure.
Prerequisites
ProLink II v2.94 or later
Important
Do not verify the zero or zero the flowmeter if a high-severity alarm is active. Correct the problem, then verify the zero or zero the flowmeter. You may verify the zero or zero the flowmeter if a lowseverity alarm is active.
Procedure
1.
Prepare the flowmeter: a. Allow the flowmeter to warm up for at least 20 minutes after applying power.
b. Run the process fluid through the sensor until the sensor temperature reaches the normal process operating temperature.
c. Stop flow through the sensor by shutting the downstream valve, and then the upstream valve if available.
d. Verify that the sensor is blocked in, that flow has stopped, and that the sensor is completely full of process fluid.
2.
Choose ProLink > Calibration > Zero Verification and Calibration > Verify Zero and wait until the procedure completes.

Definition
In general, the offset required to synchronize the left pickoff and the right pickoff under conditions of zero flow. Unit = microseconds.
The zero value obtained at the factory, under laboratory conditions.
The zero value obtained by performing a zero calibration outside the factory.
The zero value stored in the transmitter at the time a field zero calibration is begun. May be the factory zero or a previous field zero.
The zero value stored in the transmitter, typically obtained from a zero calibration procedure. It may also be configured manually. Also called “mechanical zero” or “stored zero.”
The real-time bidirectional mass flow rate with no flow damping or mass flow cutoff applied. An adaptive damping value is applied only when the mass flow rate changes dramatically over a very short interval. Unit = configured mass flow measurement unit.
A laboratory-derived value used to calculate the expected accuracy for a sensor. Under laboratory conditions at zero flow, the average flow rate is expected to fall within the range defined by the Zero Stability value (0 ± Zero Stability). Each sensor size and model has a unique Zero Stability value. Statistically, 95% of all data points should fall within the range defined by the Zero Stability value.
The procedure used to determine the zero value.
The time period over which the Zero Calibration procedure is performed. Unit = seconds.
A 3-minute running average of the Live Zero value, calculated by the transmitter. Unit = configured mass flow measurement unit.
A procedure used to evaluate the stored zero and determine whether or not a field zero can improve measurement accuracy.

Field Communicator Configure > Manual Setup > Measurements > Flow > Flow Damping
Overview
Damping is used to smooth out small, rapid fluctuations in process measurement. Damping
Value specifies the time period (in seconds) over which the transmitter will spread changes in the reported process variable. At the end of the interval, the reported process variable will reflect 63% of the change in the actual measured value.
Procedure
Set Flow Damping to the value you want to use.
The default value is 0.8 seconds. The range depends on the core processor type and the setting of Update Rate, as shown in the following table.

Tips
• A high damping value makes the process variable appear smoother because the reported value changes slowly.
• A low damping value makes the process variable appear more erratic because the reported value changes more quickly.
• The combination of a high damping value and rapid, large changes in flow rate can result in increased measurement error.
• Whenever the damping value is non-zero, the reported measurement will lag the actual measurement because the reported value is being averaged over time.

Configure process measurement
• In general, lower damping values are preferable because there is less chance of data loss, and less lag time between the actual measurement and the reported value.
• For gas applications, Micro Motion recommends setting Flow Damping to 2.56 or higher.
The value you enter is automatically rounded down to the nearest valid value. Valid damping values are shown in the following table.

Effect of Flow Damping on volume measurement
Flow Damping affects volume measurement for liquid volume data. Flow Damping also affects volume measurement for gas standard volume data. The transmitter calculates volume data from the damped mass flow data.
Interaction between Flow Damping and Added Damping
In some circumstances, both Flow Damping and Added Damping are applied to the reported mass flow value.
Flow Damping
controls the rate of change in flow process variables. Added Damping controls the rate of change reported via the mA output. If mA Output Process Variable is set to Mass
Flow Rate
, and both Flow Damping and Added Damping are set to non-zero values, flow damping is applied first, and the added damping calculation is applied to the result of the first calculation.

Configure process measurement
Procedure
Set Mass Flow Cutoff to the value you want to use.
The default value for Mass Flow Cutoff is 0.0 g/sec or a sensor-specific value set at the factory. The recommended setting is 0.05% of the sensor's rated maximum flow rate or a value below the highest expected flow rate. Do not set Mass Flow Cutoff to 0.0 g/sec.
Effect of Mass Flow Cutoff on volume measurement
Mass Flow Cutoff
does not affect volume measurement. Volume data is calculated from the actual mass data rather than the reported value.
Interaction between Mass Flow Cutoff and AO Cutoff
Mass Flow Cutoff
defines the lowest mass flow value that the transmitter will report as measured. AO Cutoff defines the lowest flow rate that will be reported via the mA output. If mA Output Process Variable
is set to Mass Flow Rate, the mass flow rate reported via the mA output is controlled by the higher of the two cutoff values.
Mass Flow Cutoff affects all reported values and values used in other transmitter behavior
(e.g., events defined on mass flow).
AO Cutoff affects only mass flow values reported via the mA output.
Example: Cutoff interaction with AO Cutoff lower than Mass Flow Cutoff

Configuration:
• mA Output Process Variable : Mass Flow Rate
• Frequency Output Process Variable : Mass Flow Rate
AO Cutoff : 10 g/sec
Mass Flow Cutoff

Overview
The slug flow parameters control how the transmitter detects and reports two-phase flow
(gas in a liquid process or liquid in a gas process).
Procedure
1.
Set Slug Low Limit to the lowest density value that is considered normal in your process.
Values below this will cause the transmitter to perform the configured slug flow action. Typically, this value is the lowest density value in the normal range of your process.
Tip
Gas entrainment can cause your process density to drop temporarily. To reduce the occurrence of slug flow alarms that are not significant to your process, set Slug Low Limit slightly below your expected lowest process density.
You must enter Slug Low Limit in g/cm
3
, even if you configured another unit for density measurement.
The default value for Slug Low Limit is 0.0 g/cm
3
. The range is 0.0 to 10.0 g/cm
3
.
2.
Set Slug High Limit to the highest density value that is considered normal in your process.
Values above this will cause the transmitter to perform the configured slug flow action. Typically, this value is the highest density value in the normal range of your process.
Tip
To reduce the occurrence of slug flow alarms that are not significant to your process, set Slug
High Limit slightly above your expected highest process density.
You must enter Slug High Limit in g/cm
3
, even if you configured another unit for density measurement.
Configuration and Use Manual
47
Configure process measurement
4.5.3
The default value for Slug High Limit is 5.0 g/cm
3
. The range is 0.0 to 10.0 g/cm
3
.
3.
Set Slug Duration to the number of seconds that the transmitter will wait for a slug flow condition to clear before performing the configured slug flow action.
The default value for Slug Duration is 0.0 seconds. The range is 0.0 to 60.0 seconds.
Slug flow detection and reporting
Slug flow is typically used as an indicator of two-phase flow (gas in a liquid process or liquid in a gas process). Two-phase flow can cause a variety of process control issues. By configuring the slug flow parameters appropriately for your application, you can detect process conditions that require correction.
Tip
To decrease the occurrence of slug flow alarms, lower Slug Low Limit or raise Slug High Limit.
•
•
A slug flow condition occurs whenever the measured density goes below Slug Low Limit or above Slug High Limit. If this occurs:
A slug flow alarm is posted to the active alarm log.
All outputs that are configured to represent flow rate hold their last “pre-slug flow” value for the configured Slug Duration.
If the slug flow condition clears before Slug Duration expires:
•
•
Outputs that represent flow rate revert to reporting actual flow.
The slug flow alarm is deactivated, but remains in the active alarm log until it is acknowledged.
If the slug flow condition does not clear before Slug Duration expires, the outputs that represent flow rate report a flow rate of 0.
If Slug Duration is set to 0.0 seconds, the outputs that represent flow rate will report a flow rate of 0 as soon as slug flow is detected.

Configure process measurement
Overview
Damping is used to smooth out small, rapid fluctuations in process measurement. Damping
Value specifies the time period (in seconds) over which the transmitter will spread changes in the reported process variable. At the end of the interval, the reported process variable will reflect 63% of the change in the actual measured value.
Procedure
Set Density Damping to the value you want to use.
The default value is 1.6 seconds. The range depends on the core processor type and the setting of Update Rate, as shown in the following table:
Core processor type
Standard
Enhanced
Update Rate
setting
Normal
Special
Not applicable
Density Damping
range
0 to 51.2 seconds
0 to 10.24 seconds
0 to 40.96 seconds
Tips
• A high damping value makes the process variable appear smoother because the reported value changes slowly.
• A low damping value makes the process variable appear more erratic because the reported value changes more quickly.
• Whenever the damping value is non-zero, the reported measurement will lag the actual measurement because the reported value is being averaged over time.
• In general, lower damping values are preferable because there is less chance of data loss, and less lag time between the actual measurement and the reported value.
The value you enter is automaticaly rounded down to the nearest valid value. The valid values for Density Damping depend on the setting of Update Rate.

Interaction between Density Damping and Added Damping
In some circumstances, both Density Damping and Added Damping are applied to the reported density value.
Density Damping
controls the rate of change in the density process variable. Added Damping controls the rate of change reported via the mA output. If mA Output Process Variable is set to
Density
, and both Density Damping and Added Damping are set to non-zero values, density damping is applied first, and the added damping calculation is applied to the result of the first calculation.

Overview
Damping is used to smooth out small, rapid fluctuations in process measurement. Damping
Value specifies the time period (in seconds) over which the transmitter will spread changes in the reported process variable. At the end of the interval, the reported process variable will reflect 63% of the change in the actual measured value.
Procedure
Enter the value you want to use for Temperature Damping.
The default value is 4.8 seconds. The range is 0.0 to 76.8 seconds.
Tips
• A high damping value makes the process variable appear smoother because the reported value changes slowly.
• A low damping value makes the process variable appear more erratic because the reported value changes more quickly.
• Whenever the damping value is non-zero, the reported measurement will lag the actual measurement because the reported value is being averaged over time.
• In general, lower damping values are preferable because there is less chance of data loss, and less lag time between the actual measurement and the reported value.
The value you enter is automaticaly rounded down to the nearest valid value. Valid values for Temperature Damping are 0, 0.6, 1.2, 2.4, 4.8, … 76.8.
Effect of Temperature Damping on process measurement
Temperature Damping affects the response speed for temperature compensation with fluctuating temperatures. Temperature compensation adjusts the process measurement to compensate for the effect of temperature on the sensor tube.
Configure pressure compensation
Pressure compensation adjusts process measurement to compensate for the pressure effect on the sensor. The pressure effect is the change in the sensor’s sensitivity to flow and density caused by the difference between the calibration pressure and the process pressure.
Tip
Not all sensors or applications require pressure compensation. The pressure effect for a specific sensor model can be found in the product data sheet located at www.micromotion.com
. If you are uncertain about implementing pressure compensation, contact Micro Motion customer service.

Overview
Update Rate controls the rate at which process data is polled and process variables are calculated. Update Rate = Special produces faster and “noisier” response to changes in the process. Do not use Special mode unless required by your application.
Tip
For systems with a standard core processor, Special mode can improve performance for applications with entrained air or Empty-Full-Empty conditions. This does not apply to systems with an enhanced core processor.
Prerequisites
Before setting Update Rate to Special:
• Check the effects of Special mode on specific process variables.
• Contact Micro Motion.
Procedure
1.
Set Update Rate as desired.
Option Description
Normal
All process data is polled at the rate of 20 times per second (20 Hz).
All process variables are calculated at 20 Hz.
This option is appropriate for most applications.
Special A single, user-specified process variable is polled at the rate of 100 times per second (100 Hz). Other process data is polled at 6.25 Hz). Some process, diagnostic, and calibration data is not polled.
All available process variables are calculated at 100 Hz.
Use this option only if required by your application.
If you change Update Rate, the settings for Flow Damping, Density Damping, and
Temperature Damping are automatically adjusted.
2.
If you set Update Rate to Special, select the process variable to be polled at 100 Hz.

Overview
Fault Timeout
controls the delay before fault actions are performed.
Restriction
Fault Timeout is applied only to the following alarms (listed by Status Alarm Code): A003, A004, A005,
A008, A016, A017, A033. For all other alarms, fault actions are performed as soon as the alarm is detected.
Procedure
Set Fault Timeout as desired.
The default value is 0 seconds. The range is 0 to 60 seconds.
If you set Fault Timeout to 0, fault actions are performed as soon as the alarm condition is detected.
The fault timeout period begins when the transmitter detects an alarm condition. During the fault timeout period, the transmitter continues to report its last valid measurements.
If the fault timeout period expires while the alarm is still active, the fault actions are performed. If the alarm condition clears before the fault timeout expires, no fault actions are performed.
Tip
ProLink II allows you to set Fault Timeout in two locations. However, there is only one parameter, and the same setting is applied to all outputs.

Postrequisites
For each channel that you configured, perform or verify the corresponding input or output configuration. When the configuration of a channel is changed, the channel’s behavior will be controlled by the configuration that is stored for the selected input or output type, and the stored configuration may not be appropriate for your process.
After verifying channel and output configuration, return the control loop to automatic control.
Configure the mA output
The mA output is used to report the configured process variable. The mA output parameters control how the process variable is reported. Your transmitter has one mA output: Channel A.
The mA output parameters include:
• mA Output Process Variable
• Lower Range Value (LRV) and Upper Range Value (URV)
• AO Cutoff
• Added Damping
• AO Fault Action and AO Fault Value
Important
Whenever you change an mA output parameter, verify all other mA output parameters before returning the flowmeter to service. In some situations, the transmitter automatically loads a set of stored values, and these values may not be appropriate for your application.

Overview
The Lower Range Value (LRV) and Upper Range Value (URV) are used to scale the mA output, that is, to define the relationship between mA Output Process Variable and the mA output level.
Note
For transmitter software v5.0 and later, if you change LRV and URV from the factory default values, and you later change mA Output Process Variable, LRV and URV will not reset to the default values. For example, if you set mA Output Process Variable to Mass Flow Rate and change the LRV and URV, then you set mA Output Process Variable to Density, and finally you change mA Output Process Variable back to Mass
Flow Rate , LRV and URV for Mass Flow Rate reset to the values that you configured. In earlier versions of the transmitter software, LRV and URV reset to the factory default values.
Procedure
Set LRV and URV as desired.
• LRV is the value of mA Output Process Variable represented by an output of 4 mA. The default value for LRV depends on the setting of mA Output Process Variable. Enter LRV in the measurement units that are configured for mA Output Process Variable.
• URV is the value of mA Output Process Variable represented by an output of 20 mA. The default value for URV depends on the setting of mA Output Process Variable. Enter URV in the measurement units that are configured for mA Output Process Variable.
Tips
For best performance:
• Set LRV
≥ LSL (lower sensor limit).
• Set URV ≤ USL (upper sensor limit).
• Set these values so that the difference between URV and LRV is ≥ Min Span (minimum span).
Defining URV and LRV within the recommended values for Min Span, LSL, and USL ensures that the resolution of the mA output signal is within range of the bit precision of the D/A converter.
Note
You can set URV below LRV. For example, you can set URV to
50
and LRV to
100
.
The mA output uses a range of 4–20 mA to represent mA Output Process Variable. Between
LRV and URV, the mA output is linear with the process variable. If the process variable drops below LRV or rises above URV, the transmitter posts an output saturation alarm.
Default values for Lower Range Value (LRV) and Upper Range
Value (URV)
Each option for mA Output Process Variable has its own LRV and URV. If you change the configuration of mA Output Process Variable, the corresponding LRV and URV are loaded and used.

Overview
AO Cutoff
(Analog Output Cutoff) specifies the lowest mass flow rate, volume flow rate, or gas standard volume flow rate that will be reported through the mA output. Any flow rates below AO Cutoff will be reported as 0.
Restriction
AO Cutoff is applied only if mA Output Process Variable is set to Mass Flow Rate, Volume Flow Rate, or Gas
Standard Volume Flow Rate
. If mA Output Process Variable is set to a different process variable, AO Cutoff is not configurable, and the transmitter does not implement the AO cutoff function.
Procedure
Set AO Cutoff as desired.
The default value for AO Cutoff is 0.0 g/sec.
Tip
For most applications, the default value of AO Cutoff should be used. Contact Micro Motion customer service before changing AO Cutoff.
Interaction between AO Cutoff and process variable cutoffs
When mA Output Process Variable is set to a flow variable (for example, mass flow rate or volume flow rate), AO Cutoff interacts with Mass Flow Cutoff or Volume Flow Cutoff. The transmitter puts the cutoff into effect at the highest flow rate at which a cutoff is applicable.
Configuration and Use Manual

• AO Cutoff = 10 g/sec
• Mass Flow Cutoff = 15 g/sec
Result: If the mass flow rate drops below 15 g/sec, all outputs representing mass flow will report zero flow.

Configuration:
• mA Output Process Variable = Mass Flow Rate
•
Frequency Output Process Variable

Result:
• If the mass flow rate drops below 15 g/sec but not below 10 g/sec:
The mA output will report zero flow.
The frequency output will report the actual flow rate.
• If the mass flow rate drops below 10 g/sec, both outputs will report zero flow.

Overview
Damping is used to smooth out small, rapid fluctuations in process measurement. Damping
Value specifies the time period (in seconds) over which the transmitter will spread changes in the reported process variable. At the end of the interval, the reported process variable will reflect 63% of the change in the actual measured value. Added Damping controls the amount of damping that will be applied to the mA output. It affects the reporting of mA
Output Process Variable
through the mA output only. It does not affect the reporting of that process variable via any other method (e.g., the frequency output or digital communications), or the value of the process variable used in calculations.
86
Micro Motion ® Model 1700 Transmitters with Analog Outputs
Integrate the meter with the control system
Note
Added Damping
is not applied if the mA output is fixed (for example, during loop testing) or if the mA output is reporting a fault. Added Damping is applied while sensor simulation is active.
Procedure
Set Added Damping to the desired value.
The default value is 0.0 seconds.
When you specify a value for Added Damping, the transmitter automatically rounds the value down to the nearest valid value.
Note
Added Damping values are affected by the setting of Update Rate and 100 Hz Variable.

Interaction between Added Damping and process variable damping
When mA Output Process Variable is set to a flow variable, density, or temperature, Added
Damping interacts with Flow Damping, Density Damping, or Temperature Damping. If multiple damping parameters are applicable, the effect of damping the process variable is calculated first, and the added damping calculation is applied to the result of that calculation.

Restriction
If you set Digital Communications Fault Action to NAN, you cannot set mA Output Fault Action or Frequency
Output Fault Action to None. If you try to do this, the transmitter will not accept the configuration.
Configure the frequency output
The frequency output is used to report a process variable. The frequency output parameters control how the process variable is reported. Your transmitter may have zero or one frequency output: Channel B can be configured as a frequency output or a discrete output.
The frequency output parameters include:
•
Frequency Output Polarity
•
Frequency Output Scaling Method
• Frequency Output Maximum Pulse Width
•
Frequency Output Fault Action
and Frequency Output Fault Value
Restriction
The process variable assigned to the primary mA output is automatically assigned to the frequency output. You cannot assign a different process variable.
Important
Whenever you change a frequency output parameter, verify all other frequency output parameters before returning the flowmeter to service. In some situations, the transmitter automatically loads a set of stored values, and these values may not be appropriate for your application.

Procedure
1.
Set Frequency Output Scaling Method.
Option Description
Frequency=Flow
(default)
Frequency calculated from flow rate
Pulses/Unit
Units/Pulse
A user-specified number of pulses represents one flow unit
A pulse represents a user-specified number of flow units
2.
Set additional required parameters.
• If you set Frequency Output Scaling Method to Frequency=Flow, set Rate Factor and
Frequency Factor .
• If you set Frequency Output Scaling Method to Pulses/Unit, define the number of pulses that will represent one flow unit.
• If you set Frequency Output Scaling Method to Units/Pulse, define the number of units that each pulse will indicate.
Calculate frequency from flow rate
The Frequency=Flow option is used to customize the frequency output for your application when you do not know appropriate values for Units/Pulse or Pulses/Unit.
If you specify Frequency=Flow, you must provide values for Rate Factor and Frequency Factor:
Rate Factor The maximum flow rate that you want the frequency output to report.
Above this rate, the transmitter will report A110: Frequency Output Saturated.
Frequency
Factor
A value calculated as follows:
FrequencyFactor =
RateFactor
T x N where:
T
Factor to convert selected time base to seconds
N
Number of pulses per flow unit, as configured in the receiving device
The resulting Frequency Factor must be within the range of the frequency output (0 to
10,000 Hz):
• If Frequency Factor is less than1 Hz,reconfigure the receiving device for a higher pulses/unit setting.
• If Frequency Factor is greater than 10,000 Hz, reconfigure the receiving device for a lower pulses/unit setting.

Integrate the meter with the control system
Procedure
1.
Set Discrete Output Source to Flow Switch, if you have not already done so.
2.
Set Flow Switch Variable to the flow variable that you want to use to control the flow switch.
3.
Set Flow Switch Setpoint to the value at which the flow switch will be triggered (after
Hysteresis
is applied).
• If the flow rate is below this value, the discrete output is ON.
• If the flow rate is above this value, the discrete output is OFF.
4.
Set Hysteresis to the percentage of variation above and below the setpoint that will operate as a deadband.
Hysteresis defines a range around the setpoint within which the flow switch will not change. The default is 5%. The valid range is 0.1% to 10%.
Example: If Flow Switch Setpoint = 100 g/sec and Hysteresis = 5%, and the first measured flow rate is above 100 g/sec, the discrete output is OFF. It will remain OFF unless the flow rate drops below 95 g/sec. If this happens, the discrete output will turn ON, and remain ON until the flow rate rises above 105 g/sec. At this point it turns OFF and will remain OFF until the flow rate drops below 95 g/sec.

Overview
Discrete Output Fault Action
controls the behavior of the discrete output if the transmitter encounters an internal fault condition.
Note
For some faults only: If Last Measured Value Timeout is set to a non-zero value, the transmitter will not implement the fault action until the timeout has elapsed.
CAUTION!
Do not use Discrete Output Fault Action as a fault indicator. If you do, you may not be able to
distinguish a fault condition from a normal operating condition. If you want to use the discrete
output as a fault indicator, see
Fault indication with the discrete output
.
Procedure
Set Discrete Output Fault Action as desired.
The default setting is None.

Configure events
An event occurs when the real-time value of a user-specified process variable moves past a user-defined setpoint. Events are used to provide notification of process changes or to perform specific transmitter actions if a process change occurs.
Your transmitter supports two event models:
• Basic event model
• Enhanced event model

Sensor simulation
Sensor simulation allows you to test the system or tune the loop without having to create the test conditions in your process. When sensor simulation is enabled, the transmitter reports the simulated values for mass flow, density, and temperature, and takes all appropriate actions. For example, the transmitter might apply a cutoff, activate an event, or post an alarm.
When sensor simulation is enabled, the simulated values are stored in the same memory locations used for process data from the sensor. The simulated values are then used throughout transmitter functioning. For example, sensor simulation will affect:

• The mass total and mass inventory values
• All volume calculations and data, including reported values, volume totals, and volume inventories
• All mass, temperature, density, or volume values logged to Data Logger
Sensor simulation does not affect any diagnostic values.
Unlike actual mass flow rate and density values, the simulated values are not temperaturecompensated (adjusted for the effect of temperature on the sensor’s flow tubes).

Overview
Process variables provide information about the state of the process fluid, such as flow rate, density, and temperature, as well as running totals. Process variables can also provide data about flowmeter operation, such as drive gain and pickoff voltage. This information can be used to understand and troubleshoot your process.
View process variables using the display
View the desired process variable(s).
If you are using the transmitter display, by default the display shows the mass flow rate, mass total, volume flow rate, volume total, temperature, density, and drive gain. The display reports the abbreviated name of the process variable (for example, DENS for density), the current value of that process variable, and the associated unit of measure (for example, G/CM3).
If desired, you can configure the display to show other process variables, such as totalizers and inventories.
If Auto Scroll is enabled, the display cycles through the configured display variables, showing each display variable for a user-specified number of seconds.

•
Perform a D3 and D4 density calibration (T-Series sensors only)
•

Options for measurement support
Micro Motion provides several measurement support procedures to help you evaluate and maintain your flowmeter's accuracy.
The following methods are available:
• Smart Meter Verification evaluates the structural integrity of the sensor tubes by comparing current tube stiffness to the stiffness measured at the factory. Stiffness is defined as the load per unit deflection, or force divided by displacement. Because a change in structural integrity changes the sensor’s response to mass and density, this value can be used as an indicator of measurement performance.
• Meter validation compares flowmeter measurements reported by the transmitter to an external measurement standard. Meter validation requires one data point.
• Calibration establishes the relationship between a process variable and the signal produced at the sensor. You can calibrate the flowmeter for zero, density, and temperature. Density and temperature calibration require two data points (low and high) and an external measurement for each.
Tips
•
•
•
Perform Smart Meter Verification at regular intervals to get the best data on your meter's performance.
To prove the meter against a regulatory standard, or to correct measurement error, use meter validation and meter factors.
Before performing a field calibration, contact Micro Motion to see if there is an alternative. In many cases, field calibrations have a negative effect on measurement accuracy.

Measurement support
Smart Meter Verification has an output mode called Continuous Measurement that allows the transmitter to keep measuring while the test is in progress. If you choose to run the test in
Last Measured Value
or Fault modes instead, the transmitter outputs will be held constant for the two minute duration of the test. If control loops depend on transmitter outputs, take appropriate action.
Avoid process instability during the test. If conditions are too unstable, the Smart Meter
Verification test will abort. To maximize process stability:
• Maintain a constant fluid pressure and temperature.
• Avoid changes to fluid composition, e.g., two-phase flow or settling.
• Maintain a constant flow rate.
Tips
•
•
The Smart Meter Verification test runs best when flow is stopped through the sensor.
Smart Meter Verification is not affected by any configured transmitter parameters for flow, density, or temperature.

Smart Meter Verification results interpretation
When the meter verification test is completed, the result is reported as Pass, Fail, or Abort.
(Some tools report the Fail result as Caution instead.)
Pass
The test result is within the specification uncertainty limit. In other words, the stiffness of the left and right pickoffs match the factory values plus or minus the specification uncertain limit. If transmitter zero and configuration match factory values, the sensor will meet factory specifications for flow and density measurement. It is expected that meters will pass meter verification every time the test is run.
142
Micro Motion ® Model 1700 Transmitters with Analog Outputs
Measurement support
Fail
The test result is not within the specification uncertainty limit. Micro Motion recommends that you immediately repeat the meter verification test. If during the failed test you had set outputs to Continue Measurement, set outputs to Fault or
Last Measured Value
instead.
•
•
If the meter passes the second test, the first result can be ignored.
If the meter fails the second test, the flow tubes may be damaged. Use your process knowledge to determine the possibilities for damage and the appropriate actions for each. These actions might include removing the meter from service and physically inspecting the tubes. At minimum, you should perform a flow validation and a density calibration.
Abort
A problem occurred with the meter verification test (e.g., process instability) or
you stopped the test manually. See
for a list of abort codes, a descript of each code, and possible actions you can take in response.

Overview
Meter validation compares flowmeter measurements reported by the transmitter to an external measurement standard. If the transmitter value for mass flow, volume flow, or density measurement is significantly different from the external measurement standard, you may want to adjust the corresponding meter factor. The flowmeter’s actual measurement is multiplied by the meter factor, and the resulting value is reported and used in further processing.
Prerequisites
Identify the meter factor(s) that you will calculate and set. You may set any combination of the three meter factors: mass flow, volume flow, and density. Note that all three meter factors are independent:
• The meter factor for mass flow affects only the value reported for mass flow.
• The meter factor for density affects only the value reported for density.
• The meter factor for volume flow affects only the value reported for volume flow or gas standard volume flow.
Important
To adjust volume flow, you must set the meter factor for volume flow. Setting a meter factor for mass flow and a meter factor for density will not produce the desired result. The volume flow calculations are based on original mass flow and density values, before the corresponding meter factors have been applied.
If you plan to calculate the meter factor for volume flow, be aware that validating volume in the field may be expensive, and the procedure may be hazardous for some process fluids. Therefore, because volume is inversely proportional to density, an alternative to direct measurement is to calculate the meter factor for volume flow from the meter factor
for instructions on this method.
Obtain a reference device (external measurement device) for the appropriate process variable.
Important
For good results, the reference device must be highly accurate.

9.4.1
Procedure
1.
Determine the meter factor as follows: a. Use the flowmeter to take a sample measurement.
b. Measure the same sample using the reference device.
c. Calculate the meter factor using the following formula:
NewMeterFactor
=
ConfiguredMeterFactor x
ReferenceMeasurement
FlowmeterMeasurement
2.
Ensure that the calculated meter factor is between 0.8 and 1.2, inclusive. If the meter factor is outside these limits, contact Micro Motion customer service.
3.
Configure the meter factor in the transmitter.
Example: Calculating the meter factor for mass flow
The flowmeter is installed and validated for the first time. The mass flow measurement from the transmitter is 250.27 lb. The mass flow measurement from the reference device is 250 lb. The mass flow meter factor is calculated as follows:
MeterFactor
MassFlow
=
1 x
250
250.27
= 0.9989
The first meter factor for mass flow is 0.9989.
One year later, the flowmeter is validated again. The mass flow measurement from the transmitter is 250.07 lb. The mass flow measurement from the reference device is
250.25 lb. The new mass flow meter factor is calculated as follows:
MeterFactor
MassFlow
=
0.9989
x
250.25
250.07
= 0.9996
The new meter factor for mass flow is 0.9996.
Alternate method for calculating the meter factor for volume flow
The alternate method for calculating the meter factor for volume flow is used to avoid the difficulties that may be associated with the standard method.
This alternate method is based on the fact that volume is inversely proportional to density.
It provides partial correction of the volume flow measurement by adjusting for the portion of the total offset that is caused by the density measurement offset. Use this method only when a volume flow reference is not available, but a density reference is available.

Perform a (standard) D1 and D2 density calibration
Density calibration establishes the relationship between the density of the calibration fluids and the signal produced at the sensor. Density calibration includes the calibration of the D1 (low-density) and D2 (high-density) calibration points.
Important
Micro Motion flowmeters are calibrated at the factory, and normally do not need to be calibrated in the field. Calibrate the flowmeter only if you must do so to meet regulatory requirements. Contact
Micro Motion before calibrating the flowmeter.
Tip
Micro Motion recommends using meter validation and meter factors, rather than calibration, to prove the meter against a regulatory standard or to correct measurement error.

Use sensor simulation for troubleshooting
When sensor simulation is enabled, the transmitter reports user-specified values for mass flow, temperature, and density. This allows you to reproduce various process conditions or to test the system.
You can use sensor simulation to help distinguish between legitimate process noise and externally caused variation. For example, consider a receiving device that reports an unexpectedly erratic flow value. If sensor simulation is enabled and the observed flow rate does not match the simulated value, the source of the problem is likely to be somewhere between the transmitter and the receiving device.
Important
When sensor simulation is active, the simulated value is used in all transmitter outputs and calculations, including totals and inventories, volume flow calculations, and concentration calculations. Disable all automatic functions related to the transmitter outputs and place the loop in manual operation. Do not enable simulation mode unless your application can tolerate these effects, and be sure to disable simulation mode when you have finished testing.

10.13
Check for radio frequency interference (RFI)
The transmitter's frequency output or discrete output can be affected by radio frequency interference (RFI). Possible sources of RFI include a source of radio emissions, or a large transformer, pump, or motor that can generate a strong electromagnetic field. Several methods to reduce RFI are available. Use one or more of the following suggestions, as appropriate to your installation.
Procedure
• Eliminate the RFI source.
• Move the transmitter.
• Use shielded cable for the frequency output or discrete output.
Terminate the shielding at the output device. If this is impossible, terminate the shielding at the cable gland or conduit fitting.
Do not terminate the shielding inside the wiring compartment.
360-degree termination of shielding is unnecessary.
10.14
Check the HART communication loop
If you cannot establish or maintain HART communications, the HART loop may be wired incorrectly.
Prerequisites
You will need:
• A copy of your transmitter installation manual
• A Field Communicator
• Optional: the HART Application Guide, available at www.hartcomm.org
194
Micro Motion ® Model 1700 Transmitters with Analog Outputs
Troubleshooting
Procedure
1.
Verify that the loop wires are connected as shown in the wiring diagrams in the transmitter installation manual.
If your HART network is more complex than the wiring diagrams in the transmitter installation manual, contact either Micro Motion or the HART Communication
Foundation.
2.
Disconnect the primary mA output wiring from the transmitter.
3.
Install a 250–1000 Ω resistor across the transmitter’s primary mA output terminals.
4.
Check the voltage drop across the resistor (4–20 mA = 1–5 VDC).
If voltage drop is less than 1 VDC, add resistance to achieve a voltage drop of greater than 1 VDC.
5.
Connect a Field Communicator directly across the resistor and attempt to communicate (poll).
If communication with the transmitter cannot be established, the transmitter may need service. Contact Micro Motion.
10.15
Check HART Address and Loop Current Mode
If the transmitter is producing a fixed current from the mA output, the Loop Current Mode parameter may be disabled.
When Loop Current Mode is disabled, the mA output produces a fixed value, and does not report process data or implement its fault action.
When HART Address is changed, some configuration tools will automatically change Loop
Current Mode .
Tip
Always verify Loop Current Mode after setting or changing HART Address.
Procedure
1.
Set HART Address as appropriate for your HART network.
The default address is 0. This is the recommended value unless the transmitter is in a multidrop network.
2.
Set Loop Current Mode to Enabled.
Configuration and Use Manual
195
Troubleshooting
10.16
Check HART burst mode
HART burst mode can cause the transmitter to output unexpected values. Burst mode is normally disabled, and should only be enabled if another device on the HART network requires burst mode communication.
1.
Check to see if burst mode is enabled or disabled.
2.
If burst mode is enabled, disable it.
10.17
Check the trimming of the mA output
If the trim values for the mA output are inaccurate, the transmitter will under-compensate or over-compensate the output.
1.
Trim the output, following the standard procedure.
2.
If this does not correct the problem, contact Micro Motion.
10.18
Check Lower Range Value and Upper Range
Value
If the process conditions fall below the configured Lower Range Value (LRV) or rise above the configured Upper Range Value (URV), the transmitter outputs may send unexpected values.
1.
Make a note of your current process conditions.
2.
Check the configuration of the LRV and URV.
10.19
Check mA Output Fault Action
mA Output Fault Action controls the behavior of the mA output if the transmitter encounters an internal fault condition. If the mA output is reporting a constant value below 4 mA or above 20 mA, the transmitter may be in a fault condition.
1.
Check the status alarms for active fault conditons.
2.
If there are active fault conditions, the transmitter is performing correctly. If you want to change its behavior, consider the following options:
• Change the setting of mA Output Fault Action.
• For the relevant status alarms, change the setting of Alarm Severity to Ignore.
3.
If there are no active fault conditions, continue troubleshooting.

10.20
Check Frequency Output Maximum Pulse
Width
If Frequency Output Maximum Pulse Width is set incorrectly, the frequency output may report an incorrect value.
Verify the configuration of Frequency Output Maximum Pulse Width.
For most applications, the default value for Frequency Output Maximum Pulse Width is appropriate. This corresponds to a 50% duty cycle.
10.21
Check Frequency Output Scaling Method
If Frequency Output Scaling Method is set incorrectly, the frequency output may report an incorrect value.
1.
Verify the configuration of Frequency Output Scaling Method.
2.
If you changed the setting of Frequency Output Scaling Method, check the settings of all other frequency output parameters.
10.22
Check Frequency Output Fault Action
The Frequency Output Fault Action controls the behavior of the frequency output if the transmitter encounters an internal fault condition. If the frequency output is reporting a constant value, the transmitter may be in a fault condition.
1.
Check the status alarms for active fault conditons.
2.
If there are active fault conditions, the transmitter is performing correctly. If you want to change its behavior, consider the following options:
• Change the setting of Frequency Output Fault Action.
• For the relevant status alarms, change the setting of Alarm Severity to Ignore.
3.
If there are no active fault conditions, continue troubleshooting.
10.23
Check Flow Direction
If Flow Direction is set inappropriately for your process, the transmitter may report unexpected flow values or totals.
The Flow Direction parameter interacts with actual flow direction to affect flow values, flow totals and inventories, and output behavior. For the simplest operation, actual process flow should match the flow arrow that is on the side of the sensor case.
Procedure
1.
Verify the actual direction of process flow through the sensor.
Configuration and Use Manual
197
Troubleshooting
2.
Verify the configuration of Flow Direction.
10.24
Check the cutoffs
If the transmitter cutoffs are configured incorrectly, the transmitter may report zero flow when flow is present, or very small amounts of flow under no-flow conditions.
There are separate cutoff parameters for mass flow rate, volume flow rate, gas standard volume flow rate (if applicable), and density. There is an independent cutoff for each mA output on your transmitter. The interaction between cutoffs sometimes produces unexpected results.
Procedure
Verify the configuration of the cutoffs.
Tip
For typical applications, Micro Motion recommends setting Mass Flow Cutoff to the zero stability value for your sensor, multiplied by 10. Zero stabiliy values can be found in the Product Data Sheet for your sensor.
10.25
Check for slug flow (two-phase flow)
Slug flow (two-phase flow, entrained gas) can cause spikes in the drive gain. This may cause the transmitter to report zero flow, or to post several different alarms.
1.
Check for slug flow alarms.
If the transmitter is not generating slug flow alarms, slug flow is not the source of your problem.
2.
Check the process for cavitation, flashing, or leaks.
3.
Monitor the density of your process fluid output under normal process conditions.
4.
Check the settings of Slug Low Limit, Slug High Limit, and Slug Duration.
Tip
You can reduce the occurrence of slug flow alarms by setting Slug Low Limit to a lower value,
Slug High Limit to a higher value, or Slug Duration to a higher value.
10.26
Check the drive gain
Excessive or erratic drive gain may indicate any of a variety of process conditions, sensor problems, or configuration problems.
198
Micro Motion ® Model 1700 Transmitters with Analog Outputs
Troubleshooting
To know whether your drive gain is excessive or erratic, you must collect drive gain data during the problem condition and compare it to drive gain data from a period of normal operation.

There should be no open circuits, that is, no infinite resistance readings. The left pickoff and right pickoff readings should be the same or very close ( ±5
Ω). If there are any unusual readings, repeat the coil resistance tests at the sensor junction box to eliminate the possibility of faulty cable. The readings for each coil pair should match at both ends.
5.
Test the terminals in the sensor junction box for shorts to case.
a. Leave the terminal blocks disconnected.
b. Remove the lid of the junction box.
c. Testing one terminal at a time, place a DMM lead on the terminal and the other lead on the sensor case.
With the DMM set to its highest range, there should be infinite resistance on each lead. If there is any resistance at all, there is a short to case.
6.
Test the resistance of junction box terminal pairs.
a. Test the brown terminal against all other terminals except the red one.
b. Test the red terminal against all other terminals except the brown one.
c. Test the green terminal against all other terminals except the white one.
d. Test the white terminal against all other terminals except the green one.
e. Test the blue terminal against all other terminals except the gray one.

Tip
If you do not know the correct value for Off-Line Password, wait 30 seconds. The password screen will time out automatically and you will be returned to the previous screen.
4.
If Scroll flashes on the display, activate the Scroll optical switch, then the Select optical switch, and then the Scroll optical switch again.
The display will prompt you through this sequence. The Scroll-Select-Scroll sequence is designed to guard against accidental activation of the off-line menu. It is not designed as a security measure.
5.
To exit a display menu and return to a higher-level menu:
• Activate Scroll until the EXIT option is displayed, then activate Select.
• If the EXIT option is not available, activate Scroll and Select simultaneously and hold until the screen returns to the previous display.
6.
To exit the display menu system, you can use either of the following methods:
• Exit each menu separately, working your way back to the top of the menu system.
• Wait until the display times out and returns to displaying process variable data.
Enter a floating-point value using the display
Certain configuration values (for example, Lower Range Value and Upper Range Value) are entered as floating-point values. The display supports both decimal notation and exponential notation for floating-point values.
The display allows you to enter a maximum of 8 characters, including the sign. The decimal point is not counted as a character. Exponential notation is used to enter values that require more than 8 characters.
Enter a floating-point value using decimal notation
Decimal notation allows you to enter values between –9999999 and 99999999. You can use the decimal point to enter values with a precision of 0 through 4 (4 characters to the right of the decimal point).
Decimal values entered via the display must meet the following requirements:
• They can contain a maximum of 8 digits, or 7 digits plus a minus sign (
−) to indicate a negative number.
• They can contain a decimal point. The decimal point does not count as a digit. The decimal point must be positioned so that the precision of the value does not exceed
4.
When you first enter the configuration screen, the current configuration value is displayed in decimal notation, and the active character is flashing. If the value is positive, no sign is displayed. If the value is negative, a minus sign is displayed.

Procedure
• To change the value:
1. Activate Select until the digit you want to change is active (flashing).
Select moves the cursor one position to the left. From the leftmost position, Select moves the cursor to the rightmost digit.
2. Activate Scroll to change the value of the active digit.
3. Repeat until all digits are set as desired.
• To change the sign of the value:
If the current value is negative, activate Select until the minus sign is flashing, then activate Scroll until the space is blank.
If the current value is positive and there is a blank space at the left of the value, activate Select until the cursor is flashing under the blank space, then activate
Scroll until the minus sign appears.
If the current value is positive and there is no blank space at the left of the value, activate Select until the cursor is flashing under the leftmost digit, then activate
Scroll
until the minus sign appears.
• To move the decimal point:
1. Activate Select until the decimal point is flashing.
2. Activate Scroll.
The decimal point is removed from its current position.
3. Activate Select and watch the position of the decimal point.
As the cursor moves to the left, the decimal point will flash between each pair of digits, up to a maximum precision of four (four digits to the right of the decimal point).
•
Tip
If the position is not valid, the decimal point is not displayed. Continue to activate Select until the decimal point appears at the right of the displayed value.
4. When the decimal point is in the desired position, activate Scroll.
The decimal point is inserted at its current position.
To save the displayed value to transmitter memory, activate Scroll and Select simultaneously and hold until the display changes.

B.1
Basic information about ProLink II
ProLink II is a software tool available from Micro Motion. It runs on a Windows platform and provides complete access to transmitter functions and data.
ProLink II requirements
To install ProLink II, you must have:
• The ProLink II installation media
• The ProLink II installation kit for your connection type
To obtain ProLink II and the appropriate installation kit, contact Micro Motion.
ProLink II documentation
Most of the instructions in this manual assume that you are already familiar with ProLink II or that you have a general familiarity with Windows programs. If you need more information than this manual provides, see the ProLink II manual (ProLink
Micro Motion
®
Transmitters: Installation and Use Manual).
®
II Software for
In most ProLink II installations, the manual is installed with the ProLink II program.
Additionally, the ProLink II manual is available on the Micro Motion documentation CD or the Micro Motion web site ( www.micromotion.com
).
ProLink II features and functions
ProLink II offers complete transmitter configuration and operation functions. ProLink II also offers a number of additional features and functions, including:
• The ability to save the transmitter configuration set to a file on the PC, and reload it or propagate it to other transmitters
• The ability to log specific types of data to a file on the PC
• A commissioning wizard

B.2.1
ProLink II messages
As you use ProLink II with a Micro Motion transmitter, you will see a number of messages and notes. This manual does not document all of these messages and notes.
Important
The user is responsible for responding to messages and notes and complying with all safety messages.
Connect with ProLink II
A connection from ProLink II to your transmitter allows you to read process data, configure the transmitter, and perform maintenance and troubleshooting tasks.
ProLink II connection types
Different connection types are available for connecting from ProLink II to the transmitter.
Choose the connection type appropriate to your network and the tasks you intend to perform.
The transmitter supports the following ProLink II connection types:
• Service port connections
• HART/Bell 202 connections
• HART/RS-485 connections
• Modbus/RS-485 7-bit connections (Modbus ASCII)
• Modbus/RS-485 8-bit connections (Modbus RTU)
When selecting a connection type, consider the following:
• Service port connections use standard connection parameters that are already defined in ProLink II, and therefore you do not have to configure them.
• HART/Bell 202 connections use standard HART connection parameters that are already defined in ProLink II. The only parameter you must configure is the transmitter address.
• Some connection types require opening the wiring compartment or the power supply compartment. These connection types should be used only for temporary connections, and may require extra safety precautions.
• Modbus connections, including service port connections, are typically faster than
HART connections.
• When you are using a HART connection, ProLink II will not allow you to open more than one window at a time. This is done to manage network traffic and optimize speed.
• You cannot make concurrent connections if the connections use the same terminals. You can make concurrent connections if the connections use different terminals.

• The ProLink III installation media
• The ProLink III installation kit for your connection type
To obtain ProLink III and the appropriate installation kit, contact Micro Motion.
ProLink III documentation
Most of the instructions in this manual assume that you are already familiar with ProLink III or that you have a general familiarity with Windows programs. If you need more information than this manual provides, see the ProLink III manual (ProLink
and Service Tool for Micro Motion
®
Transmitters: User Manual).
®
III Configuration

ProLink III messages
As you use ProLink III with a Micro Motion transmitter, you will see a number of messages and notes. This manual does not document all of these messages and notes.
Important
The user is responsible for responding to messages and notes and complying with all safety messages.
Connect with ProLink III
A connection from ProLink III to your transmitter allows you to read process data, configure the transmitter, and perform maintenance and troubleshooting tasks.
ProLink III connection types
Different connection types are available for connecting from ProLink III to the transmitter.
Choose the connection type appropriate to your network and the tasks you intend to perform.
The transmitter supports the following ProLink III connection types:
• Service port connections
• HART/Bell 202 connections
• HART/RS-485 connections
• Modbus/RS-485 7-bit connections (Modbus ASCII)
• Modbus/RS-485 8-bit connections (Modbus RTU)
When selecting a connection type, consider the following:
• Service port connections use standard connection parameters that are already defined in ProLink III, and therefore you do not have to configure them.
• HART/Bell 202 connections use standard HART connection parameters that are already defined in ProLink III. The only parameter you must configure is the transmitter address.
• Some connection types require opening the wiring compartment or the power supply compartment. These connection types should be used only for temporary connections, and may require extra safety precautions.
• Modbus connections, including service port connections, are typically faster than
HART connections.
• When you are using a HART connection, ProLink III will not allow you to open more than one window at a time. This is done to manage network traffic and optimize speed.
• You cannot make concurrent connections if the connections use the same terminals. You can make concurrent connections if the connections use different terminals.

•
Input/output (I/O) wiring terminals
F.1
Installation types
Model 1700 and Model 2700 transmitters can be installed five different ways, only one of which applies to your specific installation.
• Integral – The transmitter is mounted directly on the sensor. You do not need to install the transmitter separately, but you will need to connect power supply and I/O wiring.
Figure F-1: Integral installation
Transmitter
Sensor
• High-temperature flexible conduit – Some high-temperature meters come preinstalled with a flexible conduit between the sensor and the transmitter. You do not have to connect any wires between the transmitter and the sensor, but you do need to mount the electronics separately and connect power and I/O wiring to the transmitter.
Configuration and Use Manual
301
Transmitter components and installation wiring
Figure F-2: High-temperature flexible conduit installation
302
High-temperature flexible conduit installations use the same installation instructions as 4-wire remote installations, except that the distance between the sensor and the electronics is limited by the length of the flexible conduit.
• 4-wire remote – The transmitter is installed remotely from the sensor. You need to mount the transmitter separately from the sensor, connect a 4-wire cable between the transmitter and sensor, and connect power and I/O wiring to the transmitter.

• 9-wire remote – The transmitter and core processor are combined in a single unit that is installed remotely from the sensor. You need to mount the transmitter/core processor assembly separately from the sensor, connect a 9-wire cable between the transmitter/core processor, and connect power and I/O wiring to the transmitter.
