1.3 SMV 3000 Smart Multivariable Transmitters
About the Transmitter
The SMV 3000 Smart Multivariable Transmitter shown in Figure 1 measures three separate process variables and calculates volumetric or mass flow rate for gases, steam or liquids for output over a 4 to 20 milliampere, two-wire loop. Its general design is based on the field proven technology of our ST 3000 Smart Pressure Transmitter and meets the same high performance standards.
Figure 1 SMV 3000 Transmitter Handles Multiple Process Variable
Measurements and Calculates Flow Rate
Electronics Housing
Meter body
The SMV 3000 transmitter accepts process temperature signals from an external Resistance Temperature Detector (RTD) or any one of several common thermocouple types. Its unique measurement sensor simultaneously handles differential pressure, static pressure, and meter body temperature signals while a separate circuit processes the process temperature input. Note that the static pressure (absolute or gauge) is read from the high pressure side of the meter body.
Using stored equations in conjunction with the multiple process variable inputs, the SMV 3000 calculates a compensated volumetric or mass flow rate output for gases, liquids and steam. Its output signal is proportional to the calculated differential flow rate.

SMV Operating Modes
The SMV 3000 can transmit its output in either an analog 4 to 20 milliampere format or a Digitally Enhanced (DE) protocol format for direct digital communications with our TPS/TDC 3000 control system. In the analog format, only a selected variable is available as an output which can be any one of the following:
Differential Pressure PV1,
Static Pressure PV2,
Process Temperature PV3, or
Calculated Flow Rate PV4
Note that the secondary variable is only available as a read only parameter through the SCT or SFC. See Figure 2.

1.5 Smart Field Communicator (SFC)
About SFC Communications
The portable, battery-powered SFC serves as the common communication interface device for Honeywells family of Smartline Transmitters. It communicates with a transmitter through serial digital signals over the 4 to 20 milliampere line used to power the transmitter. A request/response format is the basis for the communication operation. The transmitter’s microprocessor receives a communication signal from the SFC, identifies the request, and sends a response message.
Figure 5 shows a simplified view of the communication interface provided by an SFC.

ATTENTION
Because of the advanced capabilities built-in to the SMV 3000, we do not recommend that you use the SFC to configure the SMV transmitter. Some of the SMVs advance functions are not supported by the SFC. Although you can use the SFC to perform certain operations, such as calibrate or re­range the transmitter, read transmitter status and diagnose faults.
Using the SFC with the SMV 3000
If you use the SFC to communicate with the SMV, you can adjust transmitter values, or diagnose potential problems from a remote location such as the control room. You can use the SFC to:
Monitor: Read the input pressure, process temperature, or
secondary variable to the transmitter in engineering units.
Display: Retrieve and display data from the transmitter or SFC
memory.

ATTENTION
Precautions for Mounting Transmitters with Small Differential Pressure Spans
The mounting position of an SMV 3000 Transmitter is critical as the transmitter spans become smaller for the absolute and/or differential pressure range. A maximum zero shift of 0.048 psi for an absolute pressure range or 1.5 in H
O for a differential pressure range can result
2
from a mounting position which is rotated 90 degrees from vertical. A typical zero shift of 0.002 psi or 0.20 in H
O can occur for a 5 degree
2
rotation from vertical.
To minimize these positional effects on calibration (zero shift), take the appropriate mounting precautions that follow for the given pressure range.
For a transmitter with a small differential pressure span, you must
ensure that the transmitter is vertical when mounting it. You do this by leveling the transmitter side-to-side and front-to-back. See Figure 9 for suggestions on how to level the transmitter using a spirit balance.
You must also zero the transmitter by adjusting the mounting position
of the transmitter. Refer to start-up procedure in Section 7 for SMV 3000 transmitter model SMA110 and transmitters with small differential pressure spans.

4.3 Piping SMV 3000 Transmitter
Summary
The actual piping arrangement will vary depending upon the process measurement requirements. Process connections can be made to standard 1/4-inch NPT female connections on 2-1/8 inch centers in the double­ended process heads of the transmitters meter body. Or, the connections in the process heads can be modified to accept 1/2 inch NPT adapter flange for manifolds on 2, 2-1/8, or 2-1/4 inch centers
The most common type of pipe used is 1/2 inch schedule 40 steel pipe. Many piping arrangements use a three-valve manifold to connect the process piping to the transmitter. A manifold makes it easy to install and remove a transmitter without interrupting the process. It also accommodates the installation of blow-down valves to clear debris from pressure lines to the transmitter.
Figure 10 shows a diagram of a typical piping arrangement using a three­valve manifold and blow-down lines for a flow measurement application.

Transmitter location
The suggested mounting location for the transmitter depends on the process to be measured. Figure 11 shows the transmitter located above the tap for gas flow measurement. This arrangement allows for condensate to drain away from the transmitter.
Figure 12 shows the transmitter located below the tap for liquid or steam flow measurement. This arrangement minimizes the static head effect of the condensate. Although the transmitter can be located level with or above the tap, this arrangement requires a siphon to protect the transmitter from process steam. (The siphon retains water as a fill fluid.”)

ATTENTION
For liquid or steam, the piping should slope a minimum of 25.4 mm (1 inch) per 305 mm (1 foot). Slope the piping down towards the transmitter if the transmitter is below the process connection so the bubbles may rise back into the piping through the liquid. If the transmitter is located above the process connection, the piping should rise vertically above the transmitter; then slope down towards the flow line with a vent valve at the high point. For gas measurement, use a condensate leg and drain at the low point (freeze protection may be required here).

General piping guidelines
Installing flange adapter
ATTENTION
When measuring fluids containing suspended solids, install permanent
valves at regular intervals to blow-down piping.
Blow-down all lines on new installations with compressed air or steam
and flush them with process fluids (where possible) before connecting these lines to the transmitters meter body.
Be sure all the valves in the blow-down lines are closed tight after the
initial blow-down procedure and each maintenance procedure after that.
Table 6 gives the steps for installing an optional 1/2 inch NPT flange adapter on the process head.
Slightly deforming the gasket supplied with the adapter before you insert it into the adapter may aid in retaining the gasket in the groove while you align the adapter to the process head. To deform the gasket, submerse it in hot water for a few minutes then firmly press it into its recessed mounting groove in the adapter.

You connect RTD leads to the TC terminals 1, 2, 3, and 4 as appropriate for the given probe type.
You connect thermocouple leads to terminals 1 (–) and 3 (+), observing polarity.
Each transmitter includes an internal ground terminal to connect the transmitter to earth ground or a ground terminal can be optionally added to the outside of the electronics housing. While it is not necessary to ground the transmitter for proper operation, we suggest that you do so to minimize the possible effects of “noise” on the output signal and provide additional protection against lightning and static discharge damage. Note that grounding may be required to meet optional approval body certification. Refer to section 1.2 CE Conformity (Europe) Notice for special conditions.
Transmitters are available with optional lightning protection if they will be used in areas highly susceptible to lightning strikes.
Barriers must be installed per manufacturers instructions for transmitters to be used in intrinsically safe installations (see control drawing 51404251 in Section 13 for additional information).

Conduit seals and Hazardous Location Installations
WARNING
Transmitters installed as explosionproof in a Class I, Division 1, Group A Hazardous (Classified) Location in accordance with ANSI/NFPA 70, the US National Electrical Code (NEC), require a “LISTED” explosionproof seal to be installed in the conduit, within 18 inches of the transmitter.
Crouse-Hinds® type EYS/EYD or EYSX/EYDX are examples of LISTED explosionproof seals that meets this requirement.
Transmitters installed as explosionproof in a Class I, Division 1, Group B, C or D Hazardous (Classified) Locations do not require an explosionproof seal to be installed in the conduit.
NOTE: Installation should conform to all national and local electrical code requirements.
When installed as explosionproof in a Division 1 Hazardous Location, keep covers tight while the transmitter is energized. Disconnect power to the transmitter in the non-hazardous area prior to removing end caps for service.
When installed as nonincendive equipment in a Division 2 Hazardous Location, disconnect power to the transmitter in the non-hazardous area, or determine that the location is non-hazardous prior to disconnecting or connecting the transmitter wires.

5.2 Establishing Communications
Off-line Versus On­line SMV Configuration
Off-line Configuration Procedures
SCT Hardware Connections
The SCT 3000 allows you to perform both off-line and on-line configuration of SMV transmitters.
Off-line configuration does not require connection to the transmitter.
By operating the SCT 3000 in the off-line mode, you can configure database files of an unlimited number of transmitters prior to receipt, save them either to hard disk or a floppy diskette, and then download the database files to the transmitters during commissioning.
An on-line session requires that the SCT is connected to the transmitter
and allows you to download previously-configured database files at any time during installation or commissioning of your field application. Note that you can also upload a transmitters existing configuration and then make changes directly to that database.
Refer to the SCT User Manual (on-line) for detailed procedures on how to off-line configure SMV transmitters using the SCT 3000.
A PC or laptop computer (host computer) which contains the SCT software program, is connected to the wiring terminals of the SMV transmitter and other smart field devices. Figure 18 shows the hardware components of the SCT.

6.2 Overview
About Configuration
Each SMV 3000 Transmitter includes a configuration database that defines its particular operating characteristics. You use the SCT 3000 to enter and change selected parameters within a given transmitters database to alter its operating characteristics. We call this process of viewing and/or changing database parameters “configuration”.
SMV configuration can be done using the SCT either on-line, where configuration parameters are written to the SMV through a direct connection with the SCT, or off-line where the transmitter configuration database is created and saved to disk for later downloading to the SMV. Figure 20 shows a graphic summary of the on-line configuration process.

SMV 3000 /SCT Connections
SFC and SMV 3000 Configuration
When using a Honeywell-defined SMV template, you should choose a file template for the temperature range and model of SMV that you wish to configure.
For example, if the SMV transmitter is a model SMA125 and you are using a J-type thermocouple as the process temperature PV3 input, you would choose the template file sma125j.hdt from the list of Honeywell templates. You would then enter the configuration parameters in the fields of the tab cards displayed in the SCT window.
Configuration is complete when you have entered all parameters in the templates tab cards, (and for flow applications you have entered all flow data in the flow compensation wizard). You then save the template file containing the SMV transmitters database as a disk file.
Refer to Section 5.2 Establishing Communications or the SCT on-line user manual for connecting the SCT and SMV for on-line configuration.
We do not recommend that you configure the SMV using the Smart Field Communicator (SFC). Some of the advanced functions of the SMV transmitter are not supported by the SFC. However you can use the SFC to perform certain operations, such as calibrate or re-range the transmitter, read transmitter status and diagnose faults.
SMV 3000 Transmitter Users Manual 1/9948
6.3 Configuring the SMV 3000 with The SCT
Using the SCT for SMV 3000 Configuration
The SCT template files have tab cards that contain data fields for the SMV parameters which you fill in. You start with the Device tab card to enter the device tag name (Tag ID) and other general descriptions. Next, you can select each tab card in order and configure each PV (PV1, secondary variable if desired, PV2, PV3, and PV4).
SMV Process Variable SCT Template Tab Card
PV1 (Differential Pressure) DPConf PV2 (Absolute Pressure or APConf or GPConf *
Gauge Pressure) * PV3 (Process Temperature) TempConf PV4 (Flow) FlowConf
* PV2 will be AP of GP depending on SMV model
Use the Flow Compensation Wizard to setup the SMV 3000 for flow applications. The flow wizard guides you through the steps necessary to complete your flow configuration. See Subsection 6.10 and Appendix C for more information about the flow wizard.
ATTENTION
In the subsections below information is given for filling in some of the SCT tab card data fields. Supplementary background information and reference data on SMV configuration that may be helpful is also presented. Use the SCT on-line help and user manual for detailed how to configure information.
If the transmitter detects an incomplete database upon power-up, it will initialize the database parameters to default conditions. A setting or
selection with a superscript d” in the following subsections identifies the factory setting.

Transmitter Tag Name and PV1 Priority
Background
Tag ID field is found on the Device tab card.
Tag ID - Enter an appropriate tag name for the transmitter containing up to eight ASCII characters which uniquely identifies the transmitter.
NOTE: It is suggeste d that when you create a database co nfiguration file fo r the
transmitter, you make the file name the same as the transmitter tag ID.
PV1 Priority - Enter “/ slash as the eighth character in tag number to set PV1 as “priority” PV in DE (digital) data broadcast, if all four PVs are selected for broadcast (turned ON). See Selecting PVs for Broadcast” on next page for an explanation on the broadcast of PVs.
Normally, PV1 has the number 1 priority unless all four PVs are selected for broadcast. Then, PV4 has the number 1 priority, PV1 is second, PV2 is third, and PV3 is fourth. However, you can set PV1 to have the top priority and PV4 to be second by entering a “/” as the eighth character in the Tag ID.
Note that the transmission rate for the various PVs depends on the number of PVs that are selected for broadcast. When more than one PV is selected, the priority PV is sent every other broadcast cycle.

LRV and URV
The Lower Range Value and the Upper Range Value fields for PV1 are found on the DPConf tab card.
PV1 (DP) Range Values
Set the LRV (which is the process input for 4 mA dc* (0%) output) and URV (which is the process input for 20 mA dc* (100%) output) for the differential pressure input PV1 by typing in the desired values on the SCT configuration .
LRV = Type in the desired value (default = 0.0)
URV = Type in the desired value
(default = 100 inH2O@39.2 °F for SMV models SMA125 and SMG170) (default = 10 inH2O@39.2 °F for SMV models SMA110)
* When transmitter is in analog mode.
ATTENTION SMV 3000 Transmitters are calibrated with inches of water ranges
using inches of water pressure referenced to a temperature of 39.2 °F (4 °C).
For a reverse range, enter the upper range value as the LRV and the
lower range value as the URV. For example, to make a 0 to 50 inH2O range a reverse range, enter 50 as the LRV and 0 as the URV.
The URV changes automatically to compensate for any changes in the
LRV and maintain the present span (URV – LRV).
If you must change both the LRV and URV, always change the LRV
first.

SQUARE ROOT
d
Factory setting.
The PV1 output is normally set for a straight linear calculation since square root is performed for PV4. However, you can select the transmitters PV1 output to represent a square root calculation for flow measurement. Thus, we refer to the linear or the square root selection as the output conformity or the output form for PV1.
For SMV 3000 transmitters measuring the pressure drop across a primary element, the flow rate is directly proportional to the square root of the differential pressure (PV1) input. The PV1output value is automatically converted to equal percent of root DP when PV1 output conformity is configured as square root.
You can use these formulas to manually calculate the percent of flow for comparison purposes.
100 = %P
Where, P = Differential pressure input in engineering units
Span = Transmitters measurement span (URV – LRV) %P = Pressure input in percent of span
%P
Therefore,
100 = % Flow

And, you can use this formula to determine the corresponding current output in milliamperes direct current.

Square Root Dropout
To avoid unstable output at PV1 readings near zero, the SMV 3000 transmitter automatically drops square root conformity and changes to linear conformity for low differential pressure readings. As shown in Figure 21, the square root dropout point is between 0.4 and 0.5 % of differential pressure input.

Damping
Background
Adjust the damping time constant for Differential Pressure (PV1) to reduce the output noise. We suggest that you set the damping to the smallest value that is reasonable for the process.
The damping values (in seconds) for PV1 are:
0.00d, 0.16, 0.32, 0.48,
1.0, 2.0, 4.0, 8.0, 16.0, and 32.0
d
Factory setting.
The electrical noise effect on the output signal is partially related to the turndown ratio of the transmitter. As the turndown ratio increases, the peak-to-peak noise on the output signal increases. You can use this formula to find the turndown ratio using the pressure range information for your transmitter.
Upper Range Limit

6.7 AP/GPConf Configuration - PV2, Continued
Background
PV2 (AP/GP or SP) Range Values (LRV and URV)
Internally, the SMV transmitter uses absolute pressure values for all flow calculations. The value entered in the Atmospheric Offset field is added to the gauge pressure input value to approximate the absolute pressure. An inaccurate atmospheric pressure offset value will result in a small error of the flow calculation. Use an absolute pressure gauge to measure the correct atmospheric pressure. A standard barometer may not give an accurate absolute pressure reading.
The Lower Range Value and the Upper Range Value fields for PV2 are found on the AP/GPConf tab card.
Set the LRV (which is the process input for 0% output and URV (which is the process input for 100% output for the static pressure input PV2 by typing in the desired values on the SCT tab card.
LRV = Type in the desired value (default = 0.0)
URV = Type in the desired value
(default = 50 psia for model SMA110) (default = 750 psia for model SMA125) (default = 3000 psig for model SMG170)
NOTE: Static pressure may be absolute or gauge pressure, depending on the model
SMV 3000 you have selected.
ATTENTION The range for PV2 is static pressure (as measured at the high pressure
port of the meter body).
The URV changes automatically to compensate for any changes in the
LRV and maintain the present span (URV – LRV).
If you must change both the LRV and URV, always change LRV first.
Damping
Adjust the damping time constant for Static Pressure (PV2) to reduce the output noise. We suggest that you set the damping to the smallest value that is reasonable for the process. The damping values (in seconds) for
PV2 are: 0.00d, 0.16, 0.32, 0.48,
1.0, 2.0, 4.0, 8.0, 16.0, and 32.0
d
Factory setting.
Background
The electrical noise effect on the output signal is partially related to the turndown ratio of the transmitter. As the turndown ratio increases, the peak-to-peak noise on the output signal increases. See the Damping paragraphs in subsection 6.6 for a formula to find the turndown ratio using the pressure range information for your transmitter.

Cold Junction Compensation
Background
If a thermocouple is used for process temperature PV3 input, you must select if the cold junction (CJ) compensation will be supplied internally by the transmitter or externally from a user-supplied isothermal block.
Specify source of cold junction temperature compensation.
Internal
External - Must also key in value of cold junction
temperature for reference.
Every thermocouple requires a hot junction and a cold junction for operation. The hot junction is located at the point of process measurement and the cold junction is located in the transmitter (internal) or at an external location selected by the user. The transmitter bases its range measurement on the difference of the two junctions. The internal or external temperature sensitive resistor compensates for changes in ambient temperature that would otherwise have the same effect as a change in process temperature.
If you configure CJ source as external, you must tell the transmitter what cold junction temperature to reference by typing in the temperature as a configuration value. For internal cold junction configuration, the transmitter measures the cold junction temperature internally.
Output Linearization
Background
For process temperature (PV3) input, configure output to represent one of these characterization selections.
Lineard - Output is in percent of temperature span.
Unlinearized - Output is in percent of resistance span for
RTD or millivolts or volts span for T/C.
d
Factory setting.
You can have the transmitter provide a linear output which is linearized to temperature for PV3 input, or a nonlinear output which is proportional to resistance for an RTD input, or millivolt or volt input for T/C input. Also, if you do switch from linear to unlinearized or vice versa, be sure you verify the LRV and URV settings after you enter the configuration data.

You can turn the transmitters temperature sensor fault detection function ON or OFF through configuration.
With the detection ON, the transmitter drives the PV3 output to
failsafe in the event of an open RTD or T/C lead condition. The direction of the failsafe indication (upscale or downscale) is determined by the failsafe jumper on the PWA, (See Subsection 8.3).
When fault detection is set to OFF, these same failsafe conditions
result in the transmitter for an open RTD sensing lead or any T/C lead. But when an open RTD compensation lead is detected, the transmitter automatically reconfigures itself to operate without the compensation lead. This means that a 4-wire RTD would be reconfigured as 3-wire RTD, if possible and thus avoiding a critical status condition in the transmitter when the transmitter is still capable of delivering a reasonably accurate temperature output.

ATTENTION
About URL and LRL
Set the URL, LRV, and URV for calculated flow rate PV4 output by typing in the desired values on the FlowConf tab card.
URL = Type in the maximum range limit that is applicable for
your process conditions. (100,000 = default)
LRV = Type in the desired value (default = 0.0)
URV = Type in the desired value (default = URL)
Be sure that you set the PV4 Upper Range Limit (URL) to desired value before you set PV4 range values. We suggest that you set the PV4 URL to equal two times the maximum flow rate (2 x URV).
The Lower Range Limit (LRL) and Upper Range Limit (URL) identify the minimum and maximum flow rates for the given PV4 calculation. The LRL is fixed at zero to represent a no flow condition. The URL, like the URV, depends on the calculated rate of flow that includes a scaling factor as well as pressure and/or temperature compensation. It is expressed as the maximum flow rate in the selected volumetric or mass flow engineering units.

ATTENTION
Low Flow Cutoff for PV4
Adjust the damping time constant for flow measurement (PV4) to reduce the output noise. We suggest that you set the damping to the smallest value that is reasonable for the process.
The damping values (in seconds) for PV4 are:

10.0, 50.0 and100.0
d
Factory setting.
The electrical noise effect on the output signal is partially related to the turndown ratio of the transmitter. As the turndown ratio increases, the peak-to-peak noise on the output signal increases. See the Damping paragraphs in subsection 6.6 for a formula to find the turndown ratio using the pressure range information for your transmitter.
For calculated flow rate (PV4), set low and high cutoff limits between 0 and 30% of Upper Range Limit for PV4 in engineering units.
Low Flow Cutoff: Low (0.0 = default)
High (0.0 = default)
Background
ATTENTION
You can set low and high low flow cutoff limits for the transmitter output based on the calculated variable PV4. The transmitter will clamp the current output at zero percent flow when the flow rate reaches the configured low limit and will keep the output at zero percent until the flow rate rises to the configured high limit. This helps avoid errors caused by flow pulsations in range values close to zero. Note that you configure limit values in selected engineering units between 0 to 30% of the upper range limit for PV4.
Figure 25 gives a graphic representation of the low flow cutoff action for sample low and high limits in engineering units of liters per minute.
If the flow LRV is not zero, the low flow cutoff output value will be calculated on the LRV and will not be 0 %.

6.10 Using Custom Engineering Units
Using Custom Units for PV4 Flow Measurement
The SCT contains a selection of preprogrammed engineering units that you can choose to represent your PV4 flow measurement. If you want the PV4 measurement to represent an engineering unit that is not one of the preprogrammed units stored in the SCT, you must select custom units and enter a tag that identifies the desired custom unit.
Using the SCT, selecting Custom Units allows you to choose a unit that is compatible with your application process. Additionally, a conversion factor must be calculated and entered when configuring the PV4 flow variable. This conversion factor is a value used to convert the standard units used by the SMV into the desired custom units. The standard units used by the SMV are:
Tonnes/hour for mass flow
Meters

6.11 Flow Compensation Wizard
Description
Standard Equation
A Flow Compensation Wizard is provided with the SCT 3000 which is used to configure PV4, the flow variable of the SMV 3000 Multivariable Transmitter. The flow compensation wizard will guide you in configuring the PV4 output for either a standard flow equation or a dynamic compensation flow equation.
You can access the flow compensation wizard by pressing the
Wizard . . .
button in the SCT /SMV 3000 configuration
window.
Refer to the SCT 3000 on-line User Manual for detailed
information for using the flow compensation wizard.
The SMV 3000 standard flow equation is a simplified version of the ASME MFC-3M flow equation. The SMV 3000 uses the standard equation to compensate for the density changes in gases, liquids and steam (saturated and superheated) and can be used with any primary flow element that behaves according to the following equation:
Flow =
PKusr
Dynamic Compensation Equation
See Appendix C for the SMV 3000 standard flow equations and examples of flow configuration using the flow compensation wizard.
The SMV 3000 dynamic compensation flow equation is the ASME flow equation as described in ASME MFC-3M, Measurement of Fluid Flow in Pipes Using Orifice, Nozzle and Venturi. The dynamic compensation flow equation should be used to increase the flow measurement accuracy and flow turndown for the primary elements listed in Table 18.

7.2 Startup Tasks
About Startup
Step Procedures
BAD PV displayed on TPS/TDC systems
Once you have installed and configured a transmitter, you are ready to start up the process loop. Startup usually includes
Simulate pressure and temperature inputs to the transmitter,
Reading inputs and outputs
Checking zero input
You can also run an optional output check to wring out an analog loop and check out individual PV outputs (in DE mode) prior to startup.
The actual steps in the startup procedure will vary based on the transmitter type, the piping arrangement and the measurement application. In general, we use the SCT to check the transmitter’s input and output under static process conditions, simulate input signals and make adjustments as required before putting the transmitter into full operation with the running process.
For SMV transmitters that are digitally integrated with Honeywell’s TPS/TDC systems, note that simulated PV readings on Universal Station displays will be flagged as BAD PV although the “PVRAW” reading will continue to be displayed will reflect the simulated input.

7.3 Running Output Check
Background
ATTENTION
Analog Output Mode Procedure
An SMV transmitter operating in the analog mode can be put into a constant-current source mode (called the output mode) to checkout other instruments in the control loop such as recorders, controllers, and positioners. Using the SCT, you can tell the transmitter to change its output to any value between 0 percent (4mA or 1V) and 100 percent (20mA or 5V) and maintain that output. This makes it easy to verify loop operation through the accurate simulation of transmitter output signals before bringing the loop on-line.
For SMV transmitters operating the DE mode, you can simulate an output for each PV individually to verify output at the digital receiver or DCS. Follow the steps in Table 20 for transmitters in DE mode.
The transmitter does not measure the given PV input or update the PV output while it is in the output mode.
IMPORTANT: Before performing this procedure, you must check the
calibration of the transmitters D/A converter. Perform the procedure The Steps to Calibrate for PV4 Output, found in the Calibration section of the SCT on-line user manual.
The procedure in Table 19 outlines the steps for checking the PV output for SMV transmitter operating in analog mode.

5
selected output. This also means that receiver instrument will be configured to match PV4 output range.
If you have selected the analog output to represent another PV, be sure it is the appropriate PV number used to check output.
Open the PV Monitor window by selecting PV Monitor from the View
6
pull down menu. Read the PV4 output.
Select FlowOutCal tab card and set output at 30% and place PV4 in
7
output mode.
Open PV Monitor window and read the PV4 in desired engineering
8
units that is equivalent to 30% output.

Select FlowOutCal tab card and clear the output mode of PV4.
Select Status tab card to verify that all transmitter outputs are in not in output mode and that there are no new messages.
You can repeat steps 6 through 10 to simulate other PV outputs, (such as PV1, PV2, or PV3).
The procedure in Table 20 outlines the steps for checking the PV outputs for SMV transmitter in DE mode.
The transmitter does not measure the given PV input or update the PV output while it is in the output mode.
For SMV transmitters that are digitally integrated with Honeywell’s TPS/TDC systems, note that PV readings on Universal Station displays will be flagged as BAD PV although the “PVRAW” reading will continue to be displayed will reflect the simulated input.

7.4 Using Transmitter to Simulate PV Input
Using SMV Transmitter in Input Mode
CAUTION
ATTENTION
You can use an SMV 3000 transmitter to simulate a PV input value through the transmitters input mode. This feature is useful to check a PVs affect on the transmitters output and compare expected readings on other analog instruments in the loop such as recorders, controllers, and positioners. For SMV transmitters operating in DE mode, inputs can be simulated for each PV to check the transmitters outputs on Universal Station displays with our TPS/TDC systems.
Using the SCT, you can tell the transmitter to change a PV input to any acceptable range value and maintain that input. This makes it easy to check PV input operation through the accurate simulation of input signals. This is especially helpful in verifying the affect of a given input on the PV4 calculated flow rate output.
NOTE: The input mode overrides the output mode.
When the transmitter is in the input mode:
The simulated PV input value is substituted for the measured input
The output reflects the simulated input.
For SMV transmitters that are digitally integrated with Honeywell’s TPS/TDC systems, note that PV readings on Universal Station displays will be flagged as BAD PV although the “PVRAW” reading will continue to be displayed will reflect the simulated input.
Input Mode Procedure
The procedure in Table 21 outlines the steps for using the transmitter in its input mode and clearing the input mode.

Select Status tab card to verify that all transmitter inputs are in not in input mode and that there are no new messages.
you must measure the absolute static pressure and then enter that value in the Atmospheric Offset field of the GPConf tab card.
Internally, the SMV transmitter uses absolute pressure values for all flow calculations. The value entered in the Atmospheric Offset field is added to the gauge pressure input value to approximate the absolute pressure. An inaccurate atmospheric pressure offset value will result in a small error of the flow calculation.
Use an absolute pressure gauge to measure the correct atmospheric pressure. A standard barometer may not give an accurate absolute pressure reading
