1. Introduction

Overview

The 83S-T Sanitary Vortex Flowmeter measures fluid flow rates using the principle of vortexshedding. The flowmeter produces a digital signal (HART protocol), a 4 to 20 mA analog signal,and a scaled pulse signal proportional to the volumetric flow rate.

Fluid flowing through the flowmeter body passes a specially shaped vortex shedder that causesvortices to form and shed alternately from sides of the shedder at a rate proportional to the flowrate of the fluid. These shedding vortices create an alternating differential pressure that is sensedby a detector located within the shedder. A pulsed voltage is generated by the detector with afrequency that is synchronous with the vortex shedding frequency. This voltage is thenconditioned by an electronic module and processed by the microcontroller to produce a digitalsignal, an analog (4 to 20 mA dc) signal, and a scaled pulse signal.

The flowtube body is connected to the electronic housing by a 4.5 m (15 ft) flexible cable. Theelectronics housing is mounted to a bracket, which must be mounted to a vibration-free wall orpipe.

2. Installation

Fundamental Installation Requirements

Foxboro vortex flowmeters shall be installed to meet all applicable local installation regulations,such as hazardous location requirements, electrical wiring codes, and mechanical piping codes.Persons involved in the installation should be trained in these code requirements to ensure thatthe installation takes maximum advantage of the safety features designed into the flowmeters.

Figure 1. 83S Sanitary Vortex Flowmeter

UnpackingThe 83S Series Vortex Flowmeter is built to be durable, but it is part of a calibrated precisionsystem and should be handled as such.

Use care when unpacking. The flowmeter is a rugged two-piece unit. The flowmeter is shippedwith the flowtube body connected to the electronics housing by a flexible cable. Do notcut or

disconnect the cable.Packing material should be disposed of in accordance with local regulations. All packing materialis nonhazardous and is generally acceptable to landfills.

Flowmeter IdentificationTo determine the model configuration of your flowmeter, refer to Figure 2. For interpretation ofthe Model Code, refer to PL 008-713.

Piping Considerations

CAUTION!

1. Prior to installation, spring back the piping on either end of the flowmeter to allowas much space as is required to install the flowmeter without damaging the flowtubeends.2. Mating end connection parts (clamps, connections, and gaskets) are required andare supplied by the user. Select a gasket or seal material which is suitable for the

process liquid.3. Support the cable that connects the flowmeter body to the electrical housing. Thesupports must be approximately 30 cm (12 in) from the flowmeter body.4. Temperature limit of cable is 105C (220F). Do not support cable on surfaceexceeding this temperature. See Figure 3.

Figure 3. Flowmeter Body Cable Support

Effects of Piping on Flowmeter Performance

The vortex shedder axis may be oriented to reduce, or in some cases eliminate, vibrationinfluence. Positioning the flowmeter body so that vibrations are parallel to the sensor diaphragms

minimizes the effect of vibrations.

The flowmeter body should be mounted in a straight, unobstructed pipe to ensure that it willperform to its fullest capabilities. The recommended minimum amount of minimum pipeupstream is shown in Table 4. There should be a minimum of eight diameters of straight pipedownstream. See Figure 4.

It is recommended that control valves, when required, be mounted downstream from theflowmeter body to ensure that back pressure is sufficient to maintain a full pipe, and to preventpressure loss sufficient to cause flashing or cavitation. Ensure that gaskets do not protrude intopipe line.

CAUTION!The piping which attaches to the flowmeter body end connections must be rigidlysupported. This minimizes the effects of piping vibration on flowmeter performance.

NOTE

1. The flowmeter should not be located near pump discharge line or suction lines.Pumps often produce oscillatory flow which may affect vortex shedding orproduce pipe vibration.

2. Flowmeters mounted near the discharge of liquid positive displacement pumpsmay experience severe flow fluctuations and cause damage to the sensor.

3. Good piping practice is to assume that for four pipe diameters upstream and twopipe diameters downstream, the internal surface of the pipe shall be free frommill scale, pits, holes, reaming scores, rifling, bumps, or other irregularities.

Bypass Piping

It is sometimes desirable to provide bypass piping if the flow cannot be interrupted for servicing

the flowmeter. See Figure 4.

WARNING!

If a bypass is used, it must also incorporate some means to relieve the pressure fromthe main line before the vortex flange bolts or clamps are loosened.

Installing the Flowmeter BodyThe 83S Sanitary Vortex Flowmeter has six different end connection possibilities. The endconnections that you have were determined from the selections made in the original specificationof your flowmeter configuration.

All end connections are welded to the flowtube body.

The mating end connections, gaskets, and clamps are supplied by you, the user.

2. Insert gaskets between body of flowmeter and adjacent flanges. Position gaskets sothat ID of each gasket is centered on ID of flowmeter and adjacent piping.

CAUTION!

1. Verify that the ID of the gaskets is larger than that of the flowmeter bore and pipe

and that they do not protrude into the flowmeter entrance or exit. Protrusion into theflowstream has an adverse affect on performance.2. Gaskets do not prevent flanges from being wetted by process fluids.

NOTE

If welding of flanges to the process piping is required, protect the inside diameter ofthe flowmeter from weld splatter. Failure to do this may adversely affect flowmeteraccuracy.

Figure 13. Installation Wiring - 4 to 20 mA Output (Two-wire)

Twisted pair wiring should be used to prevent electrical noise from interfering with the dc currentoutput signal. In some instances, shielded cable may be necessary. Grounding of the shield shouldbe installed at one point only (at the power supply). Do not ground the shield at the flowmeter.

Flowmeter connection polarities are indicated on the terminal block. If the loop is to containadditional instruments, install them between the negative terminal of the flowmeter and thepositive terminal of the receiver, as shown in Figure 13.

Power Supply and External Load

The required loop power supply voltage is based on the total loop resistance. To determine thetotal loop resistance, add the series resistance of each component in the loop (do not includeflowmeter). The required power supply voltage can be determined from Figure 14.

Figure 14. Load Requirements

The flowmeter will function with an output load less than 250 ohms, provided that a configuratoris not connected to it. Connecting a configurator to a loop with less than 250 ohms may causecommunication problems.

As an example, for a flowmeter with a loop resistance of 500 ohms, referring to Figure 14, theminimum power supply voltage is 22 V dc, while the maximum power supply voltage is 42 V dc.

Conversely, given a power supply voltage of 24 V dc, the allowable loop resistance is from 200 to565 ohms.

NOTE

1. The power supply must be capable of supplying 22 mA.2. Power supply ripple must not allow the instantaneous voltage to drop below12.5 V dc at the flowmeter.3. The recommended minimum load is 250 ohms.

Three-Wire Hook-up

Scaled Pulse Output

This wiring is primarily used to retrofit E83SA flowmeters that were wired as pulse onlyflowmeters for totalization. This wiring is typically for retrofitting existing installations.Configure the flowmeter for pulse output. Refer to Changing the Configuration (ConfigurationMenu) on page 22.

For new installations, a four-wire hook-up is recommended for scaled pulse operation to improvecommunication integrity.

A dc power supply must be used with each flowmeter and counter wiring loop to supply powerfor the flowmeter and for generation of pulses for the counter.

The dc power supply can be either a separate signal unit, a multiple unit supplying power toseveral flowmeters, or built into the receiver.

Connect the supply and counter loop wiring for pulse out (0.50 mm2or 20 AWG typical) to the

terminals in the field-terminal compartment of the flowmeter, as shown in Figure 15. To use thistype of 3-wire hookup, the blue and green terminals on the back of the module must be shorted.Refer to MI 019-196.

Figure 15. Installation Wiring - Pulse Output (Three-wire)

A resistor is required to produce a voltage drop for proper operation of the counter. A 680 , 2 Wresistor is recommended for most counters. This resistor from the counter must be connecteddirectly to the positive terminal of the power supply.

The pulse signal can cause interference to signals in adjacent signal cables. In some instances,shielded cable may be necessary. Grounding of the shield should be at one point only (at thepower supply). Do notground the shield at the flowmeter. Flowmeter connection polarities areindicated on the terminal block.

3. Operating the Flowmeter

Introduction

You can communicate with your 83S-T Vortex Flowmeter via the HART Communicator or theoptional local digital display/configurator. General instructions for using the HARTCommunicator can be found in MAN 4250, HART Communicator Product Manual. Vortex-specific instructions for using the HART Communicator are found in HART ConfigurationInstructions on page 35of this document. Complete instructions for using the LocalConfigurator are in Local Configuration Instructions on page 41.

NOTE

For proper communication with 83S-T Flowmeters, the HART Communicatormust contain the DD for the 83 Series Invensys Foxboro Flowmeter. This DD isavailable from Invensys Foxboro, or any other authorized HART Foundationsource.

PasswordsThe flowmeter itself has no password. Rather, security measures, i.e., the ability to accessfunctions such as calibration, configuration, and testing, are associated with the configuratorsused to communicate with the flowmeter. The HART Communicator has no security measureother than access to the device itself. The Local Digital Display/Configurator requires a passwordthat is user definable. See Local Configuration Instructions on page 41.

Configuration DatabaseIn order to function, the flowmeter requires specific embedded information, termed theconfiguration database. The parameters in this database are listed in Table 5, and defined inConfiguration Database on page 55.

Changing the Configuration (Configuration Menu)Using the HART Communicator or the Local Digital Display/Configurator, any parameter in theconfiguration database can be changed to fit the application by entering the Device Setup orConfiguration Menu. The specific details for doing this depend on the configurator, and aredescribed in the relevant appendix (B or C). Some general information is presented below.

Identification Parameters

NOTE

The HART protocol allows the connection of up to 15 HART devices on a single

twisted pair of wires, or over leased telephone lines, a concept known asmultidropping. In a multidrop installation, each flowmeter is identified by aunique address (1-15) referred to as the polling address. In the multidrop mode,that is, if the polling address is non-zero, the analog output is set to a fixed value of4 mA. For a nonmultidrop installation, that is, a single flowmeter loop, the pollingaddress of the flowmeter should be left in its default value (0) if the analog output isintended to indicate flow (4 to 20 mA). In a multidrop installation the pollingaddress of each flowmeter must be set to a unique integral value of 1 through 15.This can be done before or after installation with the local configurator. If using theHART Communicator, the polling address of each flowmeter must be setindividually prior to installing in a multidrop environment.

Tag Default tag may be changed as desired.

Descriptor Default descriptor may be changed as desired.

Date Default date may be changed as desired.

Message Default message may be changed as desired.

Polling Address Default address may be changed as desired. (See note below).

If the User Information is not supplied with the purchase order, the following default data for aLIQUIDwill reside in the database.

If the process fluid is not a liquid, changing the fluid type to GASautomatically brings up thedefault set shown below.

If the process fluid is not a liquid, changing the fluid type to STEAMautomatically brings up thedefault set shown below.

Flow Units Default units may be changed as desired.

Total Units Default units may be changed as desired.

Noise Rejection Keep default value On.

Signal Conditioning Keep default value On.

Low Flow Correction Should be changed to On if the low end of the operatingrange is below a Reynolds Number of 20,000.NOTE: If On is selected, actual values of the process densityand process viscosity must be entered into the database!

Low Flow Cut-In The default value for the Low Flow Cut-In is the third

level above the minimum. After installing the flowmeter,

this level can be changed such that under no-flow

conditions the flow output is zero. (See the following

Preconfiguring the MeterWith the HART Communicator, the database can be generated offline and then downloaded tothe flowmeter. The procedure for building the database consists of entering the appropriate

information as it is requested.

NOTE

The password for the local display configurator cannot be configured from theHART Communicator.

The parameters in the configuration database can be viewed without entering the Setup Menu.

This is done via the Review Menu.Local Configurator (Display Menu)

Adjusting the MeterThe following four adjustments can be made to the meter:

These appear in various places in the structures (refer to Appendixes Band C).

mA Calibration (D/A Trim)This function allows the 4 to 20 mA output of the flowmeter to be calibrated or matched to thecalibration of the receiving device.

NOTE

The flowmeter has been accurately calibrated at the factory. Recalibration of theoutput is normally notrequired unless it is being adjusted to match the calibrationof the receiving device.

Total ResetThis function allows the flow total to be reset to zero.

Low Flow Cut-InThe low flow cut-in parameter allows you to set the level above which the flowmeter begins tomeasure flow, that is, the lower range limit of the meter. This process can be carried outautomatically if the flow is turned off. Otherwise, manual selection from the following pick-list ofeight levels can be made:

For convenience, these levels are displayed as estimated flow rates in the selected flow units. Thevalue of these flow rates depend on the specific application parameters.

With the HART Comunicator, the current value is displayed and you can elect to decrease orincrease the level by one. If the level does not change when this is done, the minimum ormaximum level has been reached. In the case of the local configurator, you can select the desiredlevel from the displayed pick-list.

If Automatic mode is selected, the meter chooses the lowest level at which no signal is detectedover a 20 second time interval. You may wish to increase or decrease this setting. For instance,noise signals could be occurring at an interval greater than 20 seconds and possibly not be

detected during the automatic selection process. Repeating the auto-selection process helps toavoid this possibility.

Upper Range ValueThis parameter sets the desired maximum flowrate of the flowmeter.

Reading the MeasurementsThe Process Variables Menu (HART) or the Measurement Menu (Local) provides periodicallyupdated values of the flow rate, vortex frequency (frequency in), scaled pulse frequency (frequency

out), and flow total. The flow rate and total are presented in units of volume or mass asconfigured, the frequencies in Hz. Due to the limited size of the local display only one parameteris displayed at a time. It is possible to configure the device to display in succession two, three, orfour of the variables, as selected from a pick-list.

27

Testing the Meter and Loop (Test Menu)Entering the Diag/Service Menu for the HART Communicator or Test Menu for the LocalConfigurator allows the following two test procedures to be activated:

Self-Test

Loop Test or Loop Calibration

Self-TestThis selection checks flowmeter operation by injecting, near the front end of the electronics, aninternally generated periodic signal of known frequency. The frequency of this signal is in turnmeasured and checked against the injected signal.

Loop Test or Loop CalibrationThis selection allows the flowmeter to be used as a signal source to check and/or calibrate otherinstruments in the control loop, such as indicators, controllers, and recorders. The mA, scaled

pulse, and digital output signals can be adjusted to any value within the range limits of the meter.

Electronic Module ReplacementIf an Electronic Module is shipped as a replacement, the correct flowtube parameters will notreside in its configuration database. For proper operation of the flowmeter, the correct values mustbe entered. If the configuration database from the original meter was saved to a file, this file,containing the correct flowtube parameters, can be downloaded to the new flowmeter. If this isnot the case, they must be entered manually from the flowmeter tag.

In the latter case, enter the following data first when configuring the meter!

Model Code: Enter alphanumeric Model Code from flowmeter body tag (first 14characters).

Meter Body Serial Number: Enter alphanumeric Serial Number from flowmeter tag.

NOTE

Although the meter will operate properly without this information, it is convenientto enter it at this point.

Reference K-Factor: Enter numeric value from flowmeter body tag.

NOTE

It is not necessary to enter the units of the Reference K-Factor. The units, that is,

US (pulses/ft3) or Metric (pulses/liter), are determined internally by the meter,based on the nominal size of the meter (contained in the Model Code) and theentered numeric value of the Reference K-Factor.

4. Troubleshooting

General Troubleshooting

To maximize the usefulness of this chapter, read this General Troubleshooting section first. Then,follow the applicable procedural steps in the order presented. Persons performing troubleshootingprocedures should be suitably trained and qualified for those procedures.

NOTE

If applicable, remove flowmeter under test from multidrop environment.

Flowmeter Has Incorrect OutputCheck the configuration. Be sure the meter has been configured correctly.

Incorrect 4 to 20 mA Output

1. Be sure the upper range value is correct.

2. Check that the correct flow units are specified.

3. Check that the meter is not in the multidrop mode by verifying that the pollingaddress is zero. In the multidrop mode the mA output is fixed at a constant 4 mA.

4. Check that the meter is not in one of the application default modes.

a. For liquid the default mode is water. For many situations this may be adequate.

b. For steam the default is 125 psig saturated steam. There may be significant errorat other pressures.

c. For gas the default mode is 100 psig air. Other gases and other conditions requirethe correct configuration for density and base density.

Incorrect Digital Output

1. Check that the correct flow units are specified.

2. For custom flow units check that the conversion factor is correct. Refer toDetermining Special Measuring Units on page 33to calculate the conversion factor.

3. Check to be sure that the meter is not in one of the application default modes. Referto Item 4 above.

Incorrect Pulse Output

1. Verify that correct flow units are used. Check the pulse resolution factor.2. The scaled pulse output can only be used with a receiver that does not calculate

period, such as a counter.

Flowmeter Output Indicates Flow When There Is No FlowIn some installations, the flowmeter can indicate flow when the line is shut down. This could bethe effect of a leaking valve, sloshing fluid, or noise sources such as pump-induced pipe vibration.To eliminate these false signals, try the following:


38/72

MI 019-174 May 2007 4. Troubleshooting

30

1. Be sure there is no flow.

2. Be sure the noise rejection feature is set to ON.

3. If damping is ONand set to greater than zero, the noise spikes that exceed the lowflow cut-in appear as decaying signals less than the low flow cut-in.

4. Adjust the low flow cut-in level to produce zero output. This level can be

automatically set or manually adjusted via the configurator.5. Check that flowmeter and power supply are properly grounded. This is particularly

important for remote installations. Refer to Field Termination Wiring on page 12.

6. For remote meters, verify that signal cable has been properly terminated.

Flowmeter Output Indicates Higher Flow Rate withDecreasing Flow

1. Be sure the noise rejection feature is set to ON.

2. Adjust the low flow cut-in level to produce zero output. This can be done with

automatic or manual adjustment.

Fluctuating Output1. Verify that the signal conditioning feature is ON.

2. Fluctuations may be a true picture of the actual flow.

3. A small offset of 1 to 2% with rapid fluctuations may be caused by gaskets protrudinginto the flow stream.

No Output Troubleshooting1. Be sure there is flow.2. Check the power supply. The voltage across the + and - terminals must be between

12.5 and 42 V dc.

a. If voltage is zero, check for blown fuse in power supply.

b. If voltage is low, but not zero, the flowmeter may be loading the power supply.Remove the field terminal cover. Disconnect the + and - leads and measure thevoltage from the power supply. If the voltage returns to normal, the circuit is goodto this point. Reconnect power to the + and - terminals.

c. Remove the electronic module compartment cover. Loosen the mounting screwsand remove the electronic module from the housing. Disconnect the blue-red-yellow-green ribbon cable from the terminal blocks on the electronic module.Measure the voltage across the red and blue wires. If the voltage is normal, theelectronic module is bad. Replace the electronic module.

d. If the voltage remains low, the housing/field terminal wiring is bad. Replace thehousing or return the meter to Invensys Foxboro for repair.

3. Checking the 4 to 20 mA output loop.

a. The 4 to 20 mA loop may be monitored via the test jacks in the field outputterminal board. The signal produced will be 0.1 to 0.5 volts, corresponding to4 to 20 mA. Be sure the meter is not configured for the multidrop mode byverifying that the polling address is zero. The output is fixed at a constant 4 mA inthe multidrop mode.

b. Increase the flow to be sure that the lack of response is not caused by operationbelow the Low Flow Cut-in.

c. If there is no response to increasing flow, perform one of the following tests:

Module Test Procedure on page 31.

Sensor Test Procedure on page 31.

Module Test ProcedureThe module may be tested for input frequency with a frequency generator. Connect the

frequency generator to the outside terminals of the four-position terminal block. Connectthe positive to the brown terminal and the negative to the yellow terminal. Be sure thatloop power is connected. Increase the frequency until a flow rate is read. Do not exceed3000 Hz. If no flow measurement is indicated, check that the module is configuredcorrectly.

Sensor Test Procedure1. Remove electronic module from housing.

2. Disconnect the yellow and brown sensor leads from back of electronic module.

3. Connect sensor lead to an oscilloscope.

4. With fluid flow in the pipe, observe signal waveform on oscilloscope. Waveformshould be similar to that shown in Figure 17.

a. If waveform is similar to Figure 17, the sensor is good. If there is no output fromthe electronic module, the electronic module input stage has failed. The entireelectronic module should be replaced.

b. If there is no sensor output signal, the sensor has failed and the meter should bereplaced.

NOTE

For the sensor, be sure the signal being read is not the local power line frequency,that is, 50 or 60 Hz.

Appendix A. Determining SpecialMeasuring Units

There may be a need to use flow units that are not listed in the units menu. To enter customunits, select special from the flow and/or total units menu.

The following four entries are required to configure the flowmeter for special flow and total units.

1. Total name, maximum six characters, is required for displaying total.

2. Flow name, maximum six characters, is required for displaying the flow rate.

3. Total conversion factor for computing total.

4. Flow conversion factor for computing flow.

The conversion factors must be related to the internal software and the manner in which the

meter computes flow. The conversion factor for total is a direct conversion from ft3

to the desiredunits. The conversion factor for flow is a direct conversion from ft3/s to the desired flow units.Any table of conversion factors may be used.

Example: Barrels per hour

To measure total in barrels and flow in barrels per hour.

Total Name: bbl

Flow Name: bbl/h

Total Conversion Factor: 0.1781 bbl/ft3

Flow Conversion Factor: 0.1781 x 3600 = 641.2 bbl/h

where: 3600 = seconds/hour

Example: BTU per minute

The conversion factor for total must be in BTU/ft3. If the BTU factor is known in mass units,then it must be converted to volume units by multiplying by density. The flow factor is a directconversion from ft3/s to the desired units.

Total Name: BTU

Flow Name: BTU/m

Total Conversion Factor: (BTU/lb) x density

Flow Conversion Factor: (BTU/lb) x density x 60where: 60 = seconds/minute

Example: Calories per hour

The conversion factor for total must be in calories/ft3. If the calories factor is known in cal/kg, itmust be converted to cal/ft3 by multiplying by the density and volume conversion factors (m3to ft3). The flow factor must be related to ft3/s.

Total Name: cal


42/72

MI 019-174 May 2007

34

Flow Name: cal/h

Total Conversion Factor: (cal/kg) x density x 0.028317

where: 0.028317 = m3/ft3

Flow Conversion Factor: (cal/kg) x density x 0.028317 x 3600

Using the Local Configurator

Measurements (MEASURE)

The system starts up displaying the measured Flowrate (FLOW

), the Total (TOTAL

), or the Flowand Total (BOTH), in an alternating fashion, depending on the selection made in theCalibrate/Show menu.

Display Bar IndicatorThe analog bar indicator at the top of the display indicates the flow measurement, as a percentageof the upper range value.

NOTE

If the flow measurement is out-of-range, the bar indicator blinks.If the flowmeter is off-line, the middle four bars of the bar indicator blink.

In TEST/SET DIG, the bar indicator continues to display the flow measurement. However, inTEST/SET MA, it displays the percentage of span set.

Moving inside the Menu SystemPressing ESCstops displaying measurements, and shows the first menu item, DISPLAY. Fromhere, the four buttons allow the user to move around the menu tree, as indicated by the arrows.Press the down arrow repeatedly; the menu display cycles through each of the top level (Level 1)menu items. Refer to the menu structure diagram on the following pages as you move around.

NOTE

Each menu item has its level (1 - 4) displayed at the beginning of the top line.

The four buttons also allow the user to move up and down the picklists, as indicated by thearrows. Also, pressing ESCmoves one from the current level to the next higher level. PressingESCwithin the top level menu returns the user to the MEASUREblock.

Viewing Data (DISPLAY)The OPTIONS, PARAMS, and TAGSsub menus are all read only. You may move around inthem, but not alter any data.

In the PARAMSmenu, the display alternates for all menu items between the parameter name andvalue/units (This is also the case when viewing the Transmitter Temperature in

TEST/XMTTEMP). Go to PARAMS/URV; note that the URV and value/units alternate.In the TAGSmenu, the alphanumeric strings may be longer than the number of displayedcharacters. To shift the hidden characters into view, press the right or left arrow buttons. Go toTAGS/MODEL, and press the right arrow key several times. The MODELstring scrolls to the left,allowing you to view the hidden characters. To exit this menu item, either press the up or downarrows, or press ESCrepeatedly until the string scrolls back to its original position.

Answering a QuestionThere are several places in the menu tree where a question is displayed, such as LOOP INMANUAL?, mentioned below in Entering the Password. To answer Yes, press Enter, if No,

press ESC.

Entering the PasswordThe CALIB, TESTand CONFIGsub menus require a password (a 4-character alphanumericstring). Changing the password is addressed later. Select the CALIB, TESTor CONFIGmenufrom the top level, and press Enter at the PASSWDprompt. Two brackets surrounding 4 spaces([____]) appears on the second line of the display. The cursor, a flashing icon, appears at the firstcharacter.

To enter the password, use the up and down arrows to scroll through the list of acceptablecharacters. After selecting the desired character, press the right arrow to move to the next

character. Continue this process until the password is complete. Pressing the right arrow oncemore moves the flashing cursor to the right bracket. Pressing Enternow completes the process.Prior to pressing Enter, the left and right arrows can be used to move back and forth to modify anincorrect selection.

If you enter an incorrect password, the display indicates SORRY for 1 second, then return tothe PASSWDprompt.

After entering the correct password, the following message appears, LOOP IN MANUAL?.Press Enterif Yes, ESCif No. Yes moves the user into the calibration, test, or configurationsub-menus. No returns you to CALIBor CONFIGin the main menu.

The default password from the factory for TEST, CALIB, and CONFIGis [____], (four spaces).To enter it quickly, press the right arrow 5 times.

Activating an Edit, Pick-List or User Function Menu BlockTo open a menu block that allows the user to edit or select data or to perform a function, such asRESET TOTAL, move to the menu block and press the Right arrow.


52/72

MI 019-174 May 2007

44

Editing Numbers and StringsEditing any number or string in the menu system is done in the same way as entering thepassword above. The up and down arrows scroll through a list of acceptable characters for thecurrent position. The right arrow moves the cursor to the right; Enteraccepts the change at theend. The left arrow moves the cursor to the left; ESCcancels the change at the beginning.

There are three kinds of edit items: signed numbers, unsigned numbers, and strings.Unsigned numbers cycle through the digits 0-9, and the decimal point, with the up and downarrows. For example, try changing the CONFIG/FLUID/DENSITYitem to 8.200.

When you enter a decimal point in any position, and there is already a decimal point to the left ofthe cursor, the new decimal point overrides the old one. Change the DENSITYfrom 8.200 to82.00 by first selecting the decimal point to the right of the 2. Notice what happens when youenter the second decimal point (that is, press the Right arrow).

Signed numbers always have a + or - sign at the beginning. The + can only be changed to , andvice versa.

Finally, characters in strings may be changed to any valid character. The sequence of charactersyou can get for strings by pressing the up and down arrows is: space, A-Z, a-z, 0-9, period, dash,slash. Go to CONFIG/TAGS/MESSAGEand change it. Note that the entire data field is notvisible at once. To enter the change you must still press Enterfrom the right side of the data field,after scrolling to the right side with the right arrow.

Picking from a ListPick-List items allow the user to choose a value from a flowmeter supplied list of alternatives. Goto CONFIG/FLOW/UNITS, and press Enter. The entire bottom line of the display flashes. If youpress the up or down arrows, the display shows the next or previous choice from its list. PressingEnteraccepts the change; pressing ESCreturns the previous value.

mA Calibration (TEST/CAL 4 mA or CAL 20 mA)When opening the CAL 4 mAor CAL 20 mAmenu block, 0.5+/is displayed. To enter thisvalue, that is, to change the mA output of the flowmeter, press the up arrow to add 0.5 mA, ordown arrow to subtract 0.5 mA. By pressing the right arrow values of 0.05 and 0.005 can beselected, and entered by the up and down arrows. The display does not change when entering theselected value. To have the new calibration accepted by the flowmeter, move with the right arrowto the end of the data field. To restore the original calibration, move with the left arrow to thebeginning.

Transmitter StatusIf there is a flowmeter failure, an error message appears when entering the TESTmenu.

Changing the PasswordChanging the password is done in CONFIG/PASSWD. Before changing the password, a promptappears requesting the old password to be entered. CALIBand TESTshare the same password. Adifferent password can be used for CALIB.

Local Configurator Menu Tree

The menu tree used to carry out local configuration is shown on the following pages. Each blockon the menu diagram signifies a menu item. The text in the block indicates the title of the item,and any data displayed. The text under each block indicates the type of menu item. There are fiveitem types: Branch, Edit----, PickList, Group, and UserFunc.

Branch items do not display or edit data, but simply move you to another menu itemdepending on which key is pressed.

Edit ---- items* display a numeric (real or integer) or string value, which may beedited.

PickList items* display one of several alternatives, which may be selected. PickListitems have the choices to pick from enclosed in a dashed box to the right of the item.

Group items display, alternately, a parameter name and its value/units. You are notallowed to change them at this point in the menu tree.

UserFunc items do not display or edit data, rather they allow a built-in function to be

activated.

* Edit---- and PickList items marked R/O (read only) displays the associated data, butyou will be unable to change them at this point in the menu tree.
