Switches 1, 2, and 3 are security switches, which enable the user to disable flowmeter zeroing, disable resetting of totalizers, and writeprotect all configuration and calibration parameters.

Switch settings enable any of eight possible security modes. Different modes determine which functions are disabled and whether configuration and calibration parameters are write-protected. The following functions can be disabled:

• Flowmeter zeroing using digital communications

• Flowmeter zeroing using the Scroll and Reset buttons

• Totalizer control, with flow, using digital communications

• Totalizer control, with flow, using the Scroll and Reset buttons

• Totalizer control, with zero flow, using digital communications

• Totalizer control, with zero flow, using the Scroll and Reset buttons

Table 2-1

lists the parameters that are write-protected and functions that are disabled for each security mode. Security modes 1 through 7 are entered immediately when switches are set.

When transmitter security is set for mode 8, the transmitter meets security requirements for custody transfer described in National Institute of Standards and Technology (NIST) Handbook 44.

Once the transmitter is configured for security mode 8, the security mode cannot be changed unless a master reset is performed. A master reset causes all configuration parameters to return to their default values, and

requires complete characterization and reconfiguration

of the trans m i tt e r.

If the user attempts to enter a new security mode or change the transmitter configuration after entering security mode 8:

• Internal totalizers stop counting

• The frequency/pulse output goes to 0 Hz

• mA outputs go to 4 mA

• The display reads "SECURITY BREACH; SENSOR OK"

• Custody transfer event registers record each change made to defined configuration and calibration parameters. (For a list of these parameters, see

Table 6-2

, page 64.)

The security breach continues, and totalizers and outputs remain inactive, until the transmitter is reconfigured for security mode 8, or until a master reset has been performed. Custody transfer ev ent registers are not affected by a master reset.

• For information about event registers, see

To enter security mode 8:

1. Note the position of switch 5.

2. Set switches 1, 2, 3, and 10 to the ON position.

3. Set switches 4, 5, and 6 to the OFF position.

4. Locate the Reset button on the transmitter front panel.

5. Press and hold the Reset button for ten seconds.

6. Reset switch 5 to the desired position (as noted in Step 1).

7. Reset switch 10 to the OFF (OPERATE) position.

8. To verify the transmitter is in security mode 8, use the Scroll button to

scroll through the display screens. The transmitter is in security mode 8 if the CONFIG REG and CALIBRATE REG screens appear.

9. Leave switches 1, 2 and 3 in the ON position to maintain security

mode 8.

To verify the transmitter is in security mode 8:

Use the Scroll button to scroll through process variable screens to event register screens. If event register screens appear, the transmitter is in security mode8. For more information about us ing the Scr oll b u tt on an d transmitter display, see

Section 6.2

, page 60.

To make changes to configuration or calibration parameters once security mode 8 is entered:

1. Set switches 1, 2, and 3 to the OFF position.

2. Make changes through digital communication or with the Scroll and Reset buttons (see "Communication configuration mode", page 61). Custody transfer event registers record changes made to defined configuration and calibration parameters. For more information about digital communications, see the following instruction manuals or use AMS on-line help:

Using the HART Communicator with Micro Motion Transmitters

•

Using ProLink Software with Micro Motion Transmitters

•

Using Modbus Protocol with Micro Motion Transmitters

•

3. Set switches 1, 2, and 3 to the ON position.

To reenter security mode 8:

If security mode 8 has been established previously, and the security mode has been temporarily changed, it is not necessary to use the Reset button to reenter security mode 8. In such a case, resetting switches 1, 2, and 3 to the ON position will reenter security mode 8 immediately.

If a master reset has been performed, it is necessary to use the Reset button method to reenter security mode 8. See the procedure, above.

To change to a security mode other than mode 8:

1. Perform a master reset (see

Section 7.7

, page 79, for master reset

procedure).

2. Perform characterization and re-configuration procedures as described in any of the following instruction manuals or AMS on-line help:

Communication settings

Switch 5 enables the user to choose the standard communication configuration or user-defined parameters. With switch 10 in the ON (CONFIG) position, switches 1 through 6 can be used for setting userdefined communication parameters.

Standard communication setting

To use the standard communication configuration, set switch 5 to the STD COMM position. Setting the switch in this position establishes the following parameters:

• HART protocol on the Bell 202 standard, at 1200 baud, on the primary mA output

• Modbus protocol in RTU mode, at 9600 baud, on the RS-485 output

• 1 stop bit, odd parity

For RFT9739 software versions 3.6 and later, if switch 5 is in the STD COMM position, an error message will appear on the RFT9739 display when an attempt is made to change the communication configuration using the RFT9739 display controls.

User-defined communication settings

To establish user-defined settings, set switch 5 to the USER-DEFINED position, then use the buttons on the front panel to set baud rate; stop bits and parity; data bits, protocol, and physical layer.

• When the transmitter is shipped from the factory, the default settings are HART protocol, over RS-485, at 1200 baud, with 1 stop bit and odd parity .

• For more information on using the display, see

Section 6.2

, page 60.

Pow er-Supply and

Milliamp output scaling

Switches 7, 8, and 9 allow the user to choose 0-20 mA or 4-20 mA scaling for mA outputs, and upscale or downscale fault outputs.

Switch 7 defines the primary mA output scaling. Switch 8 defines the secondary mA output scaling. Either switch may be set in the 0-20 position or the 4-20 position.

• The mA outputs are NAMUR compliant when switches 7 and 8 are in the 4-20 position. See

Section 5.3

, page 27.

• Communication using the HART protocol over the primary mA output requires switch 7 to be set in the 4-20 position.

• If switch 7 is in the 0-20 mA position, communication may be lost if output is less than 2 mA. T o re-establish communication, move s witch 7 to the 4-20mA position.

Switch 9 defines the RFT9739 fault outputs. Fault outputs can be set for downscale or upscale levels.

• If switch 9 is set to the DWNSCALE position, mA outputs go to 0 mA if they produce a 0-20 mA current, or to 0-2 mA if they produce a 4-20 mA current; the frequency/pulse output goes to 0 Hz.

• If switch 9 is set to the UPSCALE position, mA outputs go to 22-24 mA; the frequency/pulse output goes to 15-19 kHz.

• For more information, see "Fault outputs", page 69.

5.2 Maximum wire length

RFT9739 Rack-Moun t Transmitter Instruction Manu al

Currently, there is no system for accurately estimating the maximum length of wire between the RFT9739 and a connected peripheral device.

Most applications will be able to use wire lengths up to 500 feet for 22 AWG wire (150 meters for 0.3 mm² wire), 50 feet for 28 AWG wire (15 meters for 0.1 mm² wire), between the transmitter and any peripheral device. However, these distances are estimates only.

Prior to commissioning the transmitter, a loop-test is recommended as a means for determining whether or not output signals are being received correctly at the receiving device.

The RFT9739 primary and secondary mA output signals can be independently configured, and can represent flow, density, temperature, event 1 or event 2. With a pressure transmitter, the primary and secondary mA output signals can also represent pressure. For information on configuring mA outputs for events, see any of the following manuals or AMS on-line help:

Using the HART Communicator with Micro Motion Transmitters

•

Using ProLink Software with Micro Motion Transmitters

•

Using Modbus Protocol with Micro Motion Transmitters

• The mA outputs can produce a user-selected 0-20 or 4-20 mA current.

(See "Milliamp output scaling," page 9.)

• When configured to produce 4-20 mA current, the mA output loop can supply loop-powered process indicators.

For transmitters with software version 3.8 or higher,

•

when configured to produce 4-20 mA current, the mA outputs are compliant with the NAMUR NE43 standard. (All RFT9739 transmitters shipped after November 1999 have software version 3.8 or higher.)

CAUTION

Milliamp output range has changed.

When configured for 4-20 mA, milliamp outputs will not output live signals between 2.0 and 3.8 mA, or between

20.5 and 22 mA.

Pow er-Supply and

Sensor Wiring

In compliance with the NAMUR NE43 standard:

• 4-20 mA outputs will produce a live signal from 3.8 to 20.5 mA.

• 4-20 mA outputs will not produce a signal between 2.0 and 3.8 mA, or

• 4-20 mA output performance is illustrated in

Figure 5-2. 4-20 mA output performance

Downscale fault indication level

Systems that rely on milliamp output signals in the ranges listed above might not perform as expected. For RFT9739 transmitters shipped after November 1999, outputs will saturate at 3.8 and 20.5 mA, unlike previous versions of these instruments.

Reconfigure systems as necessary.

• Primary and secondary mA output loops are isolated and floating. Additional grounding will result in optimum performance, and optimum HART communication on the primary mA output. Ensure that mA output loops are grounded properly, either at the transmitter end, or at the external device.

• The maximum allowable length for mA signal wiring is determined by measuring resistance over the signal wires and through the receiver device. Total loop resistance must not exceed 1000 ohms.

• The primary mA output must be set to the 4-20 mA mode for the Bell 202 physical layer. The Bell 202 layer will not work with the primary mA output configured as a 0-20 mA output.

• The mA output is active and cannot be converted to passive.

CAUTION

Connecting a HART device to the RFT9739 primary variable milliamp output loop could cause transmitter output error.

If the primary variable (PV) analog output is being used for flow control, connecting a HART device to the output loop could cause the transmitter 4-20 mA output to change, which would affect flow control devices.

Set control devices for manual operation before connecting a HART device to the RFT9 739 primary variable milliamp output loop.

5.4 Frequency outputs

Frequency/pulse output

The RFT9739 frequency outputs include a frequency/pulse output, a dual-channel phase-shifted frequency output for custody transfer applications, and an optocoupler output.

• The frequency output loops are isolated and floating from other circuits except the control output and external-zero input circuits. Ensure that frequency output loops are grounded properly, either at the transmitter end, or at the external device.

• The frequency output circuit uses a 2.2 kohm resistor tied to a 15-volt source that limits the current to 7 mA. The output circuit is rated to 30 VDC, with 0.1 ampere maximum sinking capability, when used in open collector mode. Open collector mode is described on page 33.

• The output is a nominal +15 V or +30 V square wave, unloaded. See "Setting voltage level for VDE output requirements," page 37.

• Output impedance is 2.2 kohm.

• For use with receivers other than Micro Motion peripheral devices, check the instruction manual for the receiver to make sure its inputvoltage and electrical-current ratings match the RFT9739 ratings.

The frequency/pulse output represents the flow rate, independent of the primary and secondary mA outputs. The frequency/pulse output can be used with all Micro Motion peripheral devices except the DMS Density Monitoring System and the PI 4-20 Process Indicator, which do not have frequency inputs.

The RFT9739 frequency/pulse output can be configured to provide any one of the following:

• Mass flow rate

• Volume flow rate

• Mass flow total

• Volume flow total

Mass flow total and volume flow total are not available with some RFT9739 transmitters shipped prior to 1998.

Use RFT9739 terminals CN2-D24 and CN2-D26 for the frequency/pulse output. T erminal D26 serves as a common return for the frequency/pulse output, dual-channel frequency output, control output, and remote zero input. See

Default configuration

Figure 5-5. Frequency/pulse output wiring

When the RFT9739 is shipped from the factory, the frequency/pulse output is internally powered by an isolated 15-volt source via a 2.2 kohm pull-up resistor. This internal current is limited to approximately 7 mA.

Configuration for increased current

Figure 5-6. Frequency/pulse output wiring for increased current

In some applications, it might be necessary to increase the current in the frequency/pulse output circuit. See

Section 5.2

Figure 5-6

continued

Configuration for constant current

Applications with high capacitance loading will benefit by wiring the frequency/pulse output circuit to maintain a constant current source of 50 mA for any load between 0 and 220 ohms. This configuration renders the control output circuit inoperable, and could affect the optocoupler and dual-channel frequency outputs.

For constant current, add a jumper across terminals CN2-Z26 and CN-D24, and a 100 to 250 ohm resistor at the PLC or pulse-counter end of the cable, as illustrated in

Figure 5-7

CAUTION

Adding a jumper across terminals CN2-Z26 and CN2-D24 renders the control output circuit inoperable.

Do not attempt to use the control output circuit after you add a jumper across terminals CN2-Z26 and CN2-D24.

The control output can be reconfigured to function properly, independent of this frequency/pulse wiring procedure. See "Control output in open collector mode," page 41.

The optocoupler and dual-channel frequency outputs could be affected by configuring the frequency/pulse output for constant current as described above. To reduce this risk, use a 250 ohm resistor, as indicated in

Configuration for open collector mode

The RFT9739 provides current to the frequency/pulse output circuit. In applications where this current must be permanently suspended, and for receiving devices that require input voltage higher than approximately 10 volts, the frequency/pulse output circuit can be used in open collector mode.

To configure the output for open collector mode, a resistor must be clipped as described below.

This procedure will permanently alter the

transmitter and cannot be reversed.

• Clip resistor R5 and add an external DC power supply and a pull-up

resistor. See

Figure 5-8

, page 34.

• The pull-up resistor must be of sufficient value to limit loop current to

less than 0.1 ampere, depending on the total loop resistance at the transmitter.

• To prevent damage to the optocoupler and dual-channel frequency

output circuits, the external voltage must not exceed 15 V.

• Resistor R5 is located on the inside of the RFT9739 back panel.

CAUTION

Clipping resistor R5 will eliminate the internal voltage source from the transmitter.

After clipping resistor R5, an external power supply is required to use the transmitter’s frequency/pulse output.

Dual-channel frequency output

The transmitter has a dual-channel, phase-shifted frequency output for custody transfer applications. The dual-channel frequency is derived from the frequency/pulse output, and represents the same flow rate as the frequency/pulse output. Each dual-channel frequency is always half the value of the frequency/pulse output. For example, if the frequency/pulse output is 4,000 Hz, each dual-channel output is 2,000 Hz. The phase shift between channels is 90 degrees.

Use RFT9739 terminals CN2-Z10, CN2-Z12, and CN2-D26 for the dualchannel frequency output. Terminal D26 serves as a common return for the dual-channel frequency output, frequency/pulse output, control output, and remote zero input. See

CAUTION

Failure to comply with requirements for intrinsic safety if the sensor is installed in a hazardou s area could result in an explosion.

Pressure transmitter wiring is not intrinsically safe. Keep pressure transmitter wiring separated from

intrinsically safe sensor wiring, power-supply wiring, and any other intrinsically safe wiring.

The RFT9739 accepts pressure input signals from a pressure transmitter for pressure compensation.

• If a pressure transmitter connected to a host controller measures gauge pressure at the sensor input, the RFT9739 can compensate for the pressure effect on the sensor. Pressure compensation is required only for the sensor models listed in

• Instructions for wiring the RFT9739 to a pressure transmitter are provided below. Instructions for configuring the RFT9739 for pressure compensation are provided in the following instruction manuals and in the AMS on-line help:

The RFT9739 pressure input terminals (CN2-Z6 and CN2-Z20) are intended for use with a pressure transmitter, and should not be connected to a control system.

If the RFT9739 is configured for pressure compensation, flowmeter measurement will not be compensated for pressure during a pressure input failure. If the signal from the pressure transmitter fails, both of the following occur:

• The RFT9739 continues to operate in non-fault mode.

• A "Pressure Input Failure" message appears on the transmitter display, a HART Communicator with the latest memory module, ProLink software version 2.4 or higher, or AMS software.

5.9 RS-485 multidrop network

The RFT9739 can be configured to communicate for any one of the following options:

• HART protocol over the RS-485 standard

• HART protocol over the Bell 202 standard

• Modbus protocol over the RS-485 standard

• Modbus protocol over the RS-485 standard and HART protocol over the Bell 202 standard

For communications configuration instructions, see "Communication configuration mode," page 61. For Bell 202 network wiring, see

Section 5.10

, page 56.

Multiple transmitters can participate in an RS-485 multidrop network that uses HART or Modbus protocol.

• Under HART protocol, an almost unlimited number of transmitters can participate in the network. Each transmitter must have a unique tag name. If polling addresses are used, up to 16 transmitters can have unique polling addresses from 0 to 15.

• Under Modbus protocol, up to 15 transmitters can participate in the network. Each transmitter must have a unique polling address from 1to 15.

To connect the transmitter to an RS-485 network, use transmitter terminals CN2-Z22 and CN2-D22.

Figure 5-29

, page 56, shows how to connect one RFT9739 or multiple RFT9739 transmitters to a host controller for RS-485 serial communication.

• Install twisted-pair, shielded cable, consisting of 24-gauge (0.3 mm²) or

larger wire, between the RFT9739 and an RS-485 communication device. Maximum cable length is 4000 feet (1200 meters).

• Some installations require a 120-ohm, ½-watt resistor at each end of

the network cable to reduce electrical reflections.

Z22 D22

RFT9739

• HART protocol over the RS-485 standard

• HART protocol over the Bell 202 standard

For communications configuration instructions, see "Communication configuration mode," page 61. For RS-485 network wiring, see

Section 5.9

, page 55.

Devices in a Bell 202 multidrop network communicate by sending and receiving signals to and from one another. HART protocol supports up to 15 transmitters in a Bell 202 multidrop network. The actual maximum number depends upon the type of transmitters, the method of installation, and other external factors. Other Rosemount SMART FAMILY transmitters can also participate in a HART-compatible network.

• A Bell 202 multidrop network uses twisted-pair wire, and allows only digital communication. Digital communication requires a sample rate of 2 to 31 seconds at 1200 baud.

• A HART Communicator or other HART-compatible control system can communicate with any device in the network over the same 2-wire pair.

Using multiple transmitters in a HART-compatible network requires assigning a unique address from 1 to 15 to each transmitter.

• Assigning an address of 1 to 15 to the transmitter causes the primary mA output to remain at a constant 4 mA level.

• The primary mA output must produce a 4-20 mA current for the Bell 202 physical layer . The Bell 202 lay er will not work with the primary mA output configured as a 0-20 mA output when the current output is 0mA.

6.3 Custody transfer event registers

Event registers are provided for security requirements for custody transfer applications. When the transmitter is configured for security mode 8 (see

Section 2.3

, page 5), the transmitter meets security requirements for custody transfer described in National Institute of Standards and Technology (NIST) Handbook 44.

Custody transfer event registers record one change for each change "session." A change session begins when the transmitter is taken out of security mode 8, and ends when security mode 8 is reentered. To begin a change session, set switches 1, 2, and 3 to the OFF position. A change session ends when switches 1, 2, and 3 are reset to the ON position. After a change session ends, security event registers will increase by one (1) if any of the parameters listed in

Table 6-2

have

been changed.

• Each register will increase up to 999, then roll over to zero.

• Custody transfer event registers cannot be reset. View the security event registers using any of the following methods:

• With the RFT9739 display. If the transmitter has a display, event

registers can be viewed from the CONFIG REG and CALIBRATE REG screens when the transmitter is configured for security mode 8.

• With ProLink software version 2.3 or higher. Refer to on-line help for

instructions.

• With AMS software. Refer to on-line help for instructions.

• With a HART Communicator.

• With a HART-compatible or Modbus-compatible master controller.

6.4 Flowmeter zeroing

Zeroing procedure

CAUTION

Failure to zero the flowmeter at initial startup could cause measurement error.

Zero the flowmeter before putting it in operation.

Flowmeter zeroing establishes flowmeter response to zero flow and sets a baseline for flow measurement.

To zero the transmitter, follow these steps:

1. Prepare the flowmeter for zeroing: a. Install the sensor according to the sensor instruction manual. b. Apply power to the transmitter, then allow it to warm up for at least

30 minutes.

c. Ensure the transmitter is in a security mode that allows flowmeter

zeroing. See "Security modes", page 6.

d. Run the process fluid to be measured through the sensor until the

sensor temperature reading approximates the normal process operating temperature.

2. Close the shutoff valve downstream from the sensor.

During the zeroing procedure, the display reads "Sensor OK CAL IN PROGRESS". The default zero time will range from 20 to 90 seconds, depending on the sensor.

After flowmeter zeroing has been completed, the mass flow rate or volume flow rate screen reappears, and the blinking "Msg" (message) indicator appears in the lower right corner. To clear the message indicator, scroll past the volume inventory screen to the message screen, which should read "Sensor OK *ERROR CLEARED*".

Diagnosing zero failure

Additional information about flowmeter zeroing

If zeroing fails, the blinking "Msg" (message) indicator appears. The message screen will indicate the zero failure with a message such as "*ZERO ERROR*", "*ZERO TOO HIGH*", or "*ZERO TOO LOW*". An error condition could indicate:

• Flow of fluid during flowmeter zeroing

• Partially empty flow tubes

• An improperly mounted sensor To clear a zeroing error, cycle power to the transmitter, ensure that the

sensor flow tubes are filled with fluid and flow is stopped, then re-zero the flowmeter again.

Flowmeter zeroing can be disabled using the transmitter’s security modes or with a remote (keyed) switch that disables the RFT9739 Reset button.

7 Troubleshooting

7.1 General guidelines

Troubleshooting a Micro Motion flowmeter is performed in two parts:

1. Tests of wiring integrity

2. Observation of the transmitter's diagnostic tools, which include

diagnostic messages and fault output levels.

CAUTION

During troublesho oting, the trans mitter could pr oduce inaccurate flow signals.

Set control devices for manual operation while troubleshooting the flowmeter.

Follow these general guidelines when troubleshooting a Micro Motion flowmeter:

• Before beginning the diagnostic process, become familiar with this instruction manual and with the instruction manual for the sensor.

• While troubleshooting a problem, leave the sensor in place, if possible. Problems can result from the specific environment in which the sensor operates.

• Check all signals under both flow and no-flow conditions. This procedure will minimize the possibility of overlooking some causes or symptoms.

Troubleshooting

continued

Fault detection indicates an interruption in the functional integrity of the sensor and the transmitter, including the sensor pickoff coils, drive coil, and RTD. Faults, such as a short or an open circuit, are detected by the HART device.

The transmitter runs continuous self-diagnostics. If these diagnostics reveal a f ailure, the HART de vice displays an error message. Self-testing allows the transmitter to check its own circuitry.

The transmitter works with a Micro Motion flow sensor to provide flow information. Therefore, many of the troubleshooting checks pertain only to the sensor. However, a HART Communicator, the ProLink program, and AMS software enable the user to perform other tests:

• Performing an

mA output test

forces the transmitter to produce a user-

specified current output of 0 to 22 mA.

• Performing a

frequency/pulse output test

forces the transmitter to produce a user-specified frequency output between 0.1 and 15,000 Hz.

• Performing an

mA output trim

allows adjustment of the primary and secondary mA outputs against a highly accurate external standard such as a digital multimeter (DMM) or receiving device.

Perform mA trim and/or test procedures, if necessary, as described in the HART Communicator or ProLink software instruction manuals, or in AMS on-line help.

• If the transmitter is in security mode 8, mA output test, mA output trim, and frequency/pulse output test procedures cannot be performed. For more information, see "Security mode 8", page 7.

• If the transmitter is in fault condition, an mA output test cannot be performed.

• If the transmitter is not properly connected to a sensor, or if the sensor is in fault condition, an mA output test cannot be performed.

Overrange and sensor error messages

Slug flow

If a sens or f a ilure occur s, if t he sen sor c ab le is f aul ty, or if meas ured flo w, measured temperature, or measured density go outside the sensor limits, the display produces one of the following messages:

• "Sensor Error"

• "Drive Overrng"

• "Input Overrange"

• "Temp Overrange"

• "Dens Overrng" To interpret overrange and sensor error messages, use the transmitter

fault output levels, a digital multimeter (DMM) or other reference device, and refer to

• Turn off power to the transmitter before unplugging terminal blocks.

• Unplug terminal blocks from the transmitter back panel to check circuits.

Programmed slug flow limits enable transmitter outputs and the display to indicate conditions such as slug flow (gas slugs in a liquid flow stream). Such conditions adversely affect sensor performance by causing erratic vibration of the flow tubes, which in turn causes the transmitter to produce inaccurate flow signals.

If the user programs slug limits, a slug flow condition causes the following to occur:

1. The message display reads "SLUG FLOW".

2. The frequency/pulse output goes to 0 Hz.

3. The mA outputs indicating the flow rate go to the level that represents

zero fl ow.

Table 7-3

, page 75, for corrective actions.

Output saturated messages

The flowmeter resumes normal operation when liquid fills the flow tubes and density stabilizes within the programmed slug flow limits.

The user can also program a slug duration, from 0 to 60 seconds, into the configuration of an RFT9739. If process density goes outside a slug flow limit, flow outputs hold their last measured value for the period of time established as the slug duration.

typical corrective actions.

If an output variable exceeds its upper range limit, the display message reads "Freq Overrange", "mA 1 Saturated" or "mA 2 Saturated". The message can mean the output variable has exceeded appropriate limits for the process, or can mean the user needs to change measurement units.

Informational messages

Information messages are described below.

Table 7-5

, page 77,

summarizes informational messages and lists typical corrective actions.

Power Reset

indicates a power failure, brownout, or power cycle has interrupted operation of the transmitter. The transmitter has a nonvolatile memory, which remains intact despite power interruptions.

Cal in Progress

indicates flowmeter zeroing in progress or density

calibration in progress.

Zero Too Noisy

indicates mechanical noise has prevented the transmitter from setting an accurate zero flow offset during transmitter zeroing.

Zero Too High

Zero Too Low

indicates f low was not complet ely sh ut off during sensor zeroing, so the transmitter has calculated a zero flow offset that is too great to allow accurate flow measurement. Zero Too Low indicates the zero flow offset is negative.

Burst Mode

indicates the user has configured the transmitter to send data in burst mode while operating under HART protocol. In burst mode, the transmitter bursts data at regular intervals.

mA 1 Fixed

mA 2 Fixed

indicates one of several conditions:

• The mA output trim or test was not completed. The output remains

fixed at the assigned level until the user completes the output trim or test procedure.

• The user has assigned a polling address other than 0 to the transmitter

for Bell 202 communication. The output remains fixed at 4 mA until the user assigns a polling address of 0 to the transmitter.

Event 1 On

Event 2 On

switches ON if an event tied to an RFT9739

output switches the output ON.

• With mass or volume total assigned to the event, the event switches

ON and OFF according to the low or high configuration of the alarm. With a LOW alarm, the event switches ON when the user resets the totalizer. With a HIGH alarm, the event switches OFF when the user resets the totalizer.

• With flow, density, temperature, or pressure assigned to the event, the

event switches OFF or ON whenever the process variable crosses the setpoint.

Security Breach

indicates the transmitter security mode has been changed from security mode 8. Clear the message by reentering security mode 8 or by performing a master reset.

Error Cleared

indicates a previous message has been cleared.

a faulty sensor. At initial startup of the transmitter, always check the following:

1. Proper cable, and use of shielded pairs

2. Proper wire termination a. Wires on correct terminals b. Wires making good connections at transmitter terminals c. Wires making good connections at the sensor terminals d. Wires properly connected at any intermediate terminal junction,

such as the user-supplied junction box between a Model DT sensor and transmitter.

If a fault condition is indicated, follow these instructions:

1. Disconnect the transmitter's power supply.

2. Unplug the terminal blocks from the transmitter back panel.

3. Use a digital multimeter (DMM) to measure resistance between wire pairs at the transmitter terminals:

Drive coil, check terminals CN1-Z2 and CN1-B2 (brown/red)

Left pickoff coil, check terminals CN1-Z8 and CN1-B8 (green/white)

Right pickoff coil, check terminals CN1-Z10 and CN1-B10 (blue/gray)

RTD, check terminals CN1-Z6 and CN1-B4 (viol et/yellow)

4. If the measured resistance is outside the range listed in

Table 7-6

repeat the measurements at the sensor terminals.

5. Reinsert the terminal blocks and restore power to the transmitter.

6. Use the DMM to troubleshoot the flowmeter.

Table 7-6. Nominal resistance ranges for flowmeter circuits

Notes

• Temperature sensor value increases 0.38675 ohms per °C increase in temperature

• Nominal resistance values will vary 40% per 100°C. However, confirming an open coil or shortened coil is more important than any slight deviation from the resistance values presented below.

• Resistance across terminals 6 and 8 (right pickoff) should be within 10% of resistance across term inals 5 and 9 (left pickoff).

7.7 Master reset

Use the switches on the transmitter control board to perform a master reset (see

Figure 1-1

, page 2, for the location of the control board). A master reset causes communication options to default to the setup used by HART Communicators, causes all other configuration options to return to their default values, and

requires complete characterization

and reconfiguration of the transmitter.

API gravity

API gravity references to 60°F (15°C). Uses correlation based on API equation 2540 for Generalized Petroleum Products.

Accuracy of corrected density calculation relative to API-2540 from 0 to 300°F:

Process fluid g/cc kg/m

°API

Diesel, heater, and fuel oils ±0.0005 ±0.5 ±0.2 Jet fuels, kerosenes, and solvents ±0.002 ±2.0 ±0.5 Crude oils and JP4 ±0.004 ±4.0 ±1.0 Lube oils ±0.01 ±10 ±2.0 Gasoline and naphthenes ±0.02 ±20 ±5.0

Minimum 4-20 mA span: 10°API

Standard volume

Outputs standard volume at 60°F or 15°C for Generalized Petroleum Products when °API is selected as density unit of measure. Accuracy of standard volume measurements depends on accuracies of mass flow rate, density, temperature and temperature-corrected °API calculation, and can be estimated using the root mean square method. Standard volume accuracy of ±0.5% of rate is typically attainable for Generalized Petroleum Products such as fuel oils, jet fuels, and kerosenes.

Pressure compensation

The analog input can accept a signal from a pressure transmitter for pressure compensation of flow and density. Range, 0-25 mA. Can be used to power independent pressure or differential pressure transmitter. Voltage sourcing capability, 15 V. Input impedance, 100 ohms.

Low-flow cutoff

Flow values below the low-flow cutoff cause digital and frequency outputs to default to zero flow levels. Each mA output may be configured for an additional low-flow cutoff.

Slug-flow limits

Transmitter senses density outside limits. Flow output remains at last measured value, for a programmed time of 0 to 60 seconds, before defaulting to zero flow.

Damping

Wide range of programmed filter time constants for damping on flow, density, and temperature. Additional damping may be applied to mA outputs.

Fault indication

Faults can be indicated by user-selected downscale (0-2 mA, 0 Hz) or upscale (22-24 mA, 15-19 kHz) output lev els. The control output can also be configured to indicate a fault condition at 0 V.

Output testing

Output testing can be conducted with a HART Communicator, the ProLink program, a Modbus host, or AMS software.

Current source

Transmitter can produce a user-specified current between 0 and 22 mA on a 0-20 mA output, or between 2 and 22 mA on a 4-20 mA output.

Frequency source

Transmitter can produce a user-specified frequency between 0.1 and 15,000 Hz.

Display

Display is a 2-line, 16-character, alphanumeric liquid crystal display (LCD). Using the transmitter’s scroll function, the user can view flow rate, density, temperature, mass and volume totals and inventory levels, and status messages on the LCD . A reset button allows the user to reset the transmitter’s flow totalizers and communication parameters, and perform the flowmeter zeroing procedure.

Rack-mount RFT9739 transmitters feature enhanced EMI immunity and the requirements of the EMC directive 89/336/EEC per EN 50081-1 (January 1992) and EN 50082-2 (March 1995) when operated at nominal rated flow measurement range. Enhanced EMI immunity is required for transmitters installed in the European Community after 1 January 1996.

For specific EMC effects within the EC, the Technical EMC file may be reviewed at Fisher-Rosemount Veenendaal.

All RFT9739 transmitters meet the requirements of SAMA PMC 33.1 (October 1978), Class 1, A, B, C (0.6% span) at nominal flow rate. All RFT9739 transmitters meet the recommendations of ANSI/IEEE C62.41 (1991) for surge and EFT.

To meet the above specifications, the transmitter must be installed with an approved Micro Motion sensor, and the sensor cable must be either doubly shielded with full contact glands, or installed in continuous, fully bonded metallic conduit. The transmitter and sensor must be directly connected to a low-impedance (less than 1 ohm) earth ground. Transmitter outputs must be run in standard twisted-pair, shielded instrument wire.
