The Remote Flow lrransmitter

1.1 General Description The Micro Motion@ Remote Flow Transmitter (RFT9729) is a microprocessor-basedmass flow transmitter. The transmitter, in conjunction with a Micro Motion flow sensor,forms a complete mass flowmeter system.

The transmitter converts the low-Ievel signals from the sensor to 4-20 mA and frequencyoutputs. The 4-20 mA signal can be configured to transmit a flow rate, temperature, ordensity signal. The frequency output is always a flow rate signal. The transmitter also pro-duces digital signals for flow rate, flow total, density, and temperature that can be read bya Rosemount@ Model 268 SMART FAMILY Interface or a HART-compatible controlsys-tern. Optionally, RS-485 can be selected as a digital communications medium.

1.2 Theory of Operation

Circuitry in the transmitter compensates for individual flow sensor characteristics,allowing interchange with any Micro Motion Model D flow sensor.

The RFf9729 interfaces with Model D Mass Flowmeters. The input circuit measures thesignals from the left and right velocity detectors on the sensor tube(s). The input data isdigitally filtered to reduce noise and increase the measurement resolution. This input datais then converted into flow rate data using the flow calibration factor and the sensedtemperature.

The drive circuit generates an oscillatory voltage to vibrate the tubes. The frequency ofoscillation is at the natural frequency of the sensor, and therefore, a process fluid densitymeasurement can be calculated from the measured natural frequency of the sensor.

A temperature amplifier converts the resistance of the sensor-mounted platinum RTD to alinearized voltage (i.e., 5 mV per OC) for digitization, temperature compensation of thesensor, and the Density Monitoring System (DMS) output. The temperature compensa-tion has a resolution of 0.1°C and a range of -240° to 450°C (-400° to 842°F).

The transmitter can be easily used with another Micro Motion sensor simply by enteringthe correct calibration data.

1.2.1 Communication The transmitter is programmed to communicate with other digital equipment using theHART protocol. For more information on transmitter protocol, please refer to the RemoteFlow Transmitter Digital Communications Instruction Manual, July, 1989, PIN 1002798.Device interconnection is accomplished by using the transmitter mA output terminals.

As an alternative, an RS-485 interface is also available through jumper configuration onthe processor board and is compatible with the transmitter protocol.

1.2.2 Fault Detection andDiagnostics

The SMART FAMILY Interface (268) allows direct digital configuration and access todiagnostics of the transmitter. The 268 connects to the transmitter via the 4-20 mAcurrent output loop and communicates with the transmitter at the transmitter site, from thecontrol room, or from any other wiring termination point in the loop. The 268 is genericand can be used with any RFT9729 transmitter. The same 268 can also be used with anyRosemount SMART FAMILY transmitter. For more information on the 268, see theinstruction manual entitled Using the SMART FAMILY Interface 268 with the MicroMotion Remote Flow Transmitter, Section 1.

The digital communications protocol is designed to assist in fault detection anddiagnostics. Fault detection is designed to ensure the functional integrity of the meter andelectronics including the velocity transducers, drive coil, and RTD. During start-up, theRFT9729 microprocessor checks its RAM and EPROM. A watchdog timer monitors theoperation of the microprocessor to ensure recovery from software malfunctions.

Detected faults, which could cause an error exceeding the accuracy specification, can bedisplayed on the 268. Within the RFT9729 itself, if a fault is detected that may indicatemalfunc.'tion of the flowmeter, the mA and frequency outputs are set to an upscale ordownscale level (see Section 3.1, Jumper Configuration on the Processor Board) as anindication that a failure has occurred. Also, the LED on the front panel flashes on at 4 Hz ifa fault condition occurs. The LED flashes on at 1 Hz during normal operation.

1.2.3 Meter Zeroing Zero flow adjustment (i.e., sensor offset adjustment) is accomplished with the Set ZeroFlow key switch on the front panel, an externally wired set zero switch, or with thecommunications protocol auto zero command. During zero flow adjustment, the LED onthe front panel remains on indicating that a zero flow calibration is in progress. Thetransmitter will not allow an excessive sensor offset during meter zeroing, protectingagainst zeroing while excessive fluid flow exists. See Section 3.3, Transmitter AutoZeroing.

1.3 Independent Exchange ofFlow Sensors andTransmitters

Transmitters and flow sensors may be replaced separately since each sensor iscalibrated at the factory and marked with flow calibration and density calibration factors.Sensors and transmitters calibrated at the factory have matching serial numbers on theirrespective nameplates. To match different transmitters and flow sensors, the calibrationfactors are simply entered into the transmitter using the communications protocol. No ad-ditional calibration or equipment is necessary. For sensors manufactured before calibra-tion factors were put on each unit, contact Micro Motion at 1-800/522-MASS (522-6277)in Boulder, Colorado for the U.S., or 31-08385-63911 in Veenendaal, the Netherlands, forEurope. Also, your local service/sales office can assist you.

1.4 Modular Electronics The electronics in the transmitter can be removed from the housing and replacedseparately, This is facilitated by modular construction and plug-in cable connectors (SeeAppendix I, Exploded Drawing). Interchangeability allows one electronics module toserve as a spare for many transmitters.

2 Transmitter Installation

2.1 General For information regarding installation of the flow sensor, please refer to the Micro MotionSensor Instruction Manual. This instruction manual is included with the sensor whenshipped from the factory.

The transmitter should be placed in an easily accessible place in a safe area.

Use separate conduits or cable trays for power and signal wiring. Cable tray installationrequires Micro Motion supplied Teflon@ wiring or equivalent cable tray compatible wiring.

Transmitter wiring connections are located on the back panel of the unit.

Wiring connections to the 025 through 0300 sensors are made within the suppliedjuction box. The juction box is not attached to the sensor when shipped. Attach and posi-tion the junction box on the sensor manifold as desired. Unscrew the junction box coverto access the 9-position terminal strip. Wiring instructions are placed in the juction boxwhen it is shipped from the factory with a sensor. Refer to these directions when makingconnections to the transmitter.

For applications in which cable temperatures are above 150°F (65°C) or below 32°F(0°C), the light blue, Teflon-jacketed cable should be used. For applications in whichtemperatures stay between 32° to 150°F (0° to 65°C), the medium blue, PVC-jacketedcable can be used. The standard cable supplied is 10 feet (3 meters) long. Up to 1000feet (300 meters) of cable can be used between the transmitter and sensor. Cable lengthsbetween 10 and 1000 feet are available from the factory.

~ Note: Operation of the meter may be detrimentally affected if cable other than Micro Mo-tion color-coded cable is used.

WARNING: To maintain intrinsic safety and performance, only low power signalcables can be routed through the conduit alongside the sensor wiring.

2.2 Installing the Transmitter When mounting the transmitter, Micro Motion recommends following the practicesdescribed below.

1. Mount the transmitter in an environment which protects it from ambient temperaturesbelow 00 or above 50°C (below 32°F or above 122°F).

2. Accessibility is important when mounting the transmitter. Be sure to mount the unit sothat it is accessible for calibration, reconfiguration, reading data or servicing.

9

2.3 Power Connections 'k / DANGER: POWER MUST BE OFF WHEN MAKING WIRING CONNECTIONS.

The transmitter comes set up for either 12 to 30 VDG, 100/115 VAG, or 220/230 VAG.

CAUTION: Power supply voltage must agree with the voltage stated on theselector switch mounted on the back panel.

AC input power connections are made at seperate terminals of the transmitter indicatedwith P, N, and the ground symbol. The individual terminal blocks may be disconnectedand removed from the housing for ease of wiring and service. When the meter is usedwith a OC power supply, terminal 20 is positive and terminal 28 is negative. Earth groundis established at the ground lug at the back panel and must be connected (See Fig. 2-1 ).

CAUTION: Failure to connect earth ground to the ground lug in the terminalcompartment will nullify the meter's intrinsically safe rating.

2.4 Signal Wiring; Sensor tothe Transmitter

2.4.1 Cable Connections Signal connections are made via the interconnect cable between the sensor unit andterminals 8 through 26 of the transmitter. Refer to Figures 2-2 for Models 06 through0300 and Figure 2-3 for the Model 0600. Only low power signal cables may be routedthrough conduit alongside the sensor wiring if intrinsic safety requirements must bemaintained.

The transmitter end of the cable must be prepared in the field. Micro Motion, Inc. suppliesthe necessary butt-splices, sp'ade-Iugs, shrink-tubing, solder-sleeve connection wire, andinstructions with each meter. Individual wires are color-coded for easy identification.Refer to Figure 2-2 or 2-3 to connect cable to the transmitter.

Wiring connections to the 025 through 0300 sensors are made within the supplied junc-tion box. The junction box is not attached to the sensor when shipped. Attach and posi-tion the junction box on the sensor manifold as desired. Unscrew the junction box coverto access the 9-position terminal strip. Wiring instructions are placed in the junction boxwhen it is shipped from the factory with a sensor. Refer to these directions when makingconnections to the transmitter.

~ Note: For 7-wire feedthrough sensors, the wires must be paired exactly as shown below.~ If the cable is not supplied by Micro Motion, Inc., make certain each pair is individually

shielded and that 20 gauge or larger diameter wire is used. The ground shield for the wirepair connected to terminal 14 and 16 must be connected to the yellow wire at the sensorjunction box and to terminal 12 at the transmitter. Be sure that the bare shields are insu-lated against potential shorting, such as to the meter case.

-Wires connected to transmitter terminals 10d (brown) and 8d (red) must be paired to-gether.

-Wires connected to terminals 14d (orange) and 16d (violet) must be paired together.

-Wires connected to terminals 20d (green) and 24d (blue) must be paired together.

-Ground shield for the pair connected to terminals 14d and 16d must connect to terminal12d (yellow)

-Ground shields for the other wire pairs connect to terminal 26d at the transmitter and arenot connected at the sensor.

For 9-wire feedthrough sensors, the pairing is as follows:

-Wires connected to transmitter terminals 10d (brown) and Bd (red) must be paired to-gether.

11

Wires connected to terminals 14d (orange) and 16d (violet) must be paired together.

Wires connected to terminals 20d (green) and 18d (white) must be paired together.

Wires connected to terminals 24d (blue) and 22d (gray) must be paired together.

-Ground shield for the pair connected to terminals 14d and 16d must connect to terminal12d (yellow)

-Ground shields for the other wire pairs connect to terminal 26d at the transmitter and arenot connected at the sensor.

2.4.2 Sensor Conduit

Connections

Flexible conduit shou!d be UL listed as explosion-proof. Explosion-proof conduit is notrequired with the sensor wiring for intrinsic safety on sensors up to and including theD300. The connection must, however, be sealed.

2.4.3 Intrinsically Safe WiringRequirements

The terminal area of the transmitter is partitioned to separate intrinsically safe wiring fromnon-intrinsically safe wiring. Intrinsically safe wiring to the sensor is labeled "IntrinsicallySafe Terminals." Only sensor wiring should enter this connector.

2.5 Transmitter Output Wiring Wiring to output devices should be separated from input power wiring to avoid possibleelectrical interference. Therefore, separate connectors are provided for output devices.Outputs are not intrinsically safe.

2.5.1 Analog Output Wiring When connecting a receiver to the RFT9729 milliamp output circuit, terminals 14b and16b are used. Terminal 16b is the signal line (+) and terminal 14b is the return (-). Thenegative signal (terminal 14) may be grounded or left ungrounded since it is galvanicallyisolated up to :t50 VDC. Twisted pair, shielded cable should be used for long runs.

The 4-20 mA signal output can power loop-powered process indicators, such as the Mi-cro Motion Model PI 4-20 Process Indicator. A minimum loop resistance of 250 ohms isrequired for SMART FAMILY communication. The maximum loop resistance cannot ex-ceed 1000 ohms. Shields for the output signals should be connected to ground only atthe transmitter end (terminal 2z, 4 b d z).

12

2.5.2 Frequency Output Wiring

(Optionally replacableby 2nd current output)

The frequency output is galvanically isolated up to :f:50 VDC. The output circuit is rated to30 VDC, 0.1 ampere maximum sinking capability. The output from the transmitter is anominal 15 volt logic level square wave, unloaded. The output impedance is 2.2k ohms atthe 15 volt logic level. If receivers other than Micro Motion products are used, please referto their instruction or operating manuals their input voltage and current requirements.

To connect a frequency output receiver, use terminal 28b (+) as the signal line andterminal 24 (-) as the return. The frequency output wiring should be twisted pair and nosmaller than 22 gauge shielded cable. Shields for the output signals should beconnected to ground only at the transmitter end (terminal 2z, 4 b d z).

2.5.3 Flow Direction Wiring To connect the transmitter for flow direction indication, use terminal 26b (+) as the signalline and terminal 24b (-) as the return. The output circuit is rated to 30 VDC, 0.1 amperemaximum sinking capability. The output from the transmitter is a nominal 0 to 15 voltlogic level, unloaded. The output impedance is 2.2k ohms at the 15 volt logic level. Withforward flow, the output is high (+15 V); with reverse flow, the output is low (0 V). Nearzero flow, this output could be in either state due to zero stability. The flow direction out-put can be used as an input to directional totalizers such as the Micro Motion DRT.

2.5.4 OMS Wiring To connect the RFT9729 to a Density Monitoring System (DMS), use three-wire shieldedcable. Use of a DMS barrier is not necessary with the RFT9729. No more than 500 feet ofshielded cable should be used between the RFT9729 and the DMS. Wire size should be22 gauge or larger diameter.

2.5.5 RS-485 Wiring To connect the RFT9729 to an RS-485 network, use terminal 10b as the "A" line andterminal12b as the "8" line. RS-485 wiring should not exceed 4000 feet (1200 meters) oftwisted pair cable. Cable should consist of 24 gauge or larger diameter wire. Twisted pair,shielded cabl~ should be used if the cable passes through any area which might produceelectromagnetic interference.

A 120 ohm, V2 watt resistor should be installed at each end of the network cable. Thesetermination resistors ensure proper communications by reducing electrical reflections inthe cable. See Figure 2-4, RS-485 Wiring.

As many as 15 RFT9729 units can be connected to a single network. Using the RFT9729in a networking (multidrop) mode requires each transmitter to be assigned a unique ad-dress in order to prevent contention on the line. In the RS-485 networking mode, it maybe desirable to engage the "485 mA Live" jumper selection (see Section 3.1, JumperConfiguration on the Processor Board) in order to preserve active milliamp outputs oneach transmitter. For further information on the communications protocol requirementsneeded to implement an RS-485 network, refer to the Remote Flow Transmitter DigitalCommunications Instruction Manual, July, 1 1989, PIN 1002789, or contact Micro Mo-tion, Inc. at 1-8001322-JUMP, in the U.S. or at 31-08385-63312 in Europe.

2.5.6 Multidrop Wiring forthe Milliamp Output

To connect the RFT9729 in a HART compatible network, the milliamp outputs from eachtransmitter in the network need to be connected together feeding into a common load re-sistor of approximately 250 ohms. Before connecting each transmitter into the network,the transmitter must be assigned a unique multidrop address using the numbers 1through 15. Doing this will default the milliamp output to a constant 4 mA level. The "485mA Live" jumper (see Section 3.1) should not be engaged in this mode of operation tolimit the overall current into the common load resistor.

A maximum of 10 transmitters may be connected in a HART multidrop network. OtherRosemount SMART FAMILY transmitters may participate in a HART compatible network.See Figure 2-5, HART Network Wiring. A single 268 or HART compatible control systemcan communicate with any of the transmitters in the network over the same two wire pair.

Twisted pair,shielded cabl~ should be used if the cable passes through any area which might produceelectromagnetic interference.

A 120 ohm, 112 watt resistor should be installed at each end of the network cable. Thesetermination resistors ensure proper communications by reducing electrical reflections inthe cable. See Figure 2-4, RS-485 Wiring.

3.1 Jumper Configuration onthe Processor Board

Four user-selectable jumpers are used to configure the RFT9729. These jumpers are la-beled DISABLE/ENABLE, SCALE DWN/UP, 485/268 and 485 mA Live. They areconfigured at the factory before shipping for ENABLE, SCALE DWN, 268, and with nojumper on 485 mA Live unless otherwise specified at the time of the sales order.

< ! > CAUTION: Power should be off when changing the position of jumpers.

To change the jumper settings, remove the sliding top cover to access the processorboard (see Appendix I). Locate the jumpers and reconfigure according to applicationrequirements (see Figures 3-1 and 3-2).

DISABLE/ENABLE {write protect): When this jumper is set to DISABLE, the RFT9729will allow configuration changes to be made using the communications protocol. Whenthe jumper is set to ENABLE, the RFT9729 will not allow configuration changes using thecommunications protocol. If this jumper is set to ENABLE, the error message shownbelow will be displayed when configuration changes with the 268 are attempted.

ERR-Xmtr Security 011

Pro-

ceed

SCALE DWN/UP: This jumper allows the user to establish the fault alarm (i.e., auto zerofailure, sensor failure, electronics failure, or temperature sensor out of range) for the top orbottom of the current or frequency scale. When the jumper is set for UPSCALE and a faultcondition occurs, the LED on the front panel flashes at 4 Hz, the frequency output goes to11 ,520 Hz, and the milliamp output goes to 22 mA. When the jumper is set for

DOWNSCALE and a fault condition occurs, the LED on the front panel flashes at 4 Hz,the frequency output goes to 0 Hz, and the milliamp output goes to 2 mA.

485/268: This jumper allows you to configure the RFT9729 to communicate using eitherthe RS-485 or the Bell 202 signaling standard. The 268 requires the Bell 202 signalstandard. Therefore, when the 485 jumper setting is used, the 268 cannot be used toconfigure the transmitter. When using RS-485, terminals 10b and 12b are used for digitalcommunications.

485 mA Live: When an RFT9729 is assigned a multidrop address other than 0, themilliamp output is automatically defaulted to a constant 4 mA level unless this jumper isengaged. This jumper should be used when several transmitters are in an RS-485multidrop arrangement and the analog output is to remain live. If the multidrop RS-485feature is not used, the jumper need not be engaged.

3.2 Power After the meter has been correctly wired, the power supply voltage can be applied. Properoperation of the meter is indicated by the LED indicator on the front panel flashing on at 1Hz.

3.3 Transmitter Auto Zeroing Close the shut-off valve downstream of the sensor. The sensor should be completelyfilled with the process fluid.

~Note: Fluid flow through the sensor must be completely stopped or the zero flow settingwill be incorrect. Problems setting zero flow occasionally occur because of leakagethrough valves.

The transmitter can be zeroed three ways; 1) with the key switch on the front panel, 2)with a remote set zero switch (wired across terminals 6b and Bb of CN2) and, 3) with anauto zero command using the communications protocol. The LED in the terminalcompartment turns on after 2 seconds of zero switch closure and remains on continuous-ly while a zero flow calibration is in progress (see Section 3.6, Using the LED).

Zeroing normally takes about 30 seconds. The LED will again flash on at 1 Hz after theoperation is complete. If auto zeroing fails, the LED will flash at 4 Hz signifying an errorcondition. An auto zero error condition could signify that excessive fluid is still flowing, thesensor tubes are not completely full, or that the sensor is improperly mounted. An autozero error can be cleared by performing another auto zero after correcting the problem orby turning power off, then on again.

3.4 Using the LED The LED is used to indicate 4 conditions.

1) The LED flashes on at 1 Hz during nominal operation (on 25% of the time, off 75% ofthe time).

2) The LED remains on continuously when a zero flow calibration (auto zero) is in prog-ress.

3) The LED flashes on at 4 Hz if a fault condition occurs.

4) The LED blinks off at 1 Hz during a slug flow condition (on 75% of the time, off 25% ofthe time).

3.5 General Guidelines There are a number of general guidelines that should be followed when trouble-shootinga Micro Motion flowmeter. Before beginning the diagnostic process, become familiar withthe Micro Motion Sensor Instruction Manual. This manual provides detailed installation in-formation pertaining to the sensor.

If possible, leave the sensor in place when trying to trouble-shoot a problem. Problemsare often a result of the specific environment in which the sensor operates.

Next, check all signals under both flow and no-flow conditions. This procedure helpsensure that causes or symptoms will not be overlooked.

21

3.5.1 Symptom Definitions In order to effectively trouble-shoot a malfunctioning flowmeter, the symptoms of failuremust be accurately identified. Once this is accomplished, their causes can be eliminated.As previously stated, the problem should be specified in as much detail as possible.Following are the four main symptoms found in the field and their definitions.

No Output: A "no output" condition exists when there is flow through the meter and nooutput is registered.

Unresponsive Output: The output remains constant even though the actual flow rate

changes.

Erratic Output: The output changes randomly, i.e., it is unrelated to changes in actualflow rate, it is erratic.

Intermittent Output: Intermittent output starts and stops randomly. While present, theoutput accurately reflects the flow rate.

3.6 Trouble-shooting The 268 is designed to assist the user in fault detection, diagnostics, and trouble-shooting. The 268 displays messages which pertain to equipment problems or mistakesmade in entering data. See the instruction manual entitled Using the SMART FAMILYInterface 268 with the Micro Motion Remote Flow Transmitter, Section 5, SoftwareDiagnostics with the 268, for information on use of the 268 for fault detection and ondiagnostics display messages.

Fault detection is designed to ensure the functional integrity of the sensor and theelectronics, including the velocity transducers, drive coil, and resistance temperaturedevice (RTD). Faults that do not manifest themselves in some obvious electrical formcannot be detected.

The RFT9729 runs continuous self-diagnostics. If these diagnostics reveal a failure, the268 screen displays an error message. In addition, there are several tests that check oradjust the output circuitry of the transmitter.

When using the 268, the following test features are found under the test branch.

Analog Output Test This test requires the transmitter to produce a desired current output. This output mustbe between 2 and 22 mA. See the instruction manual entitled Using the SMART FAMILYInterface 268 with the Micro Motion Remote Flow Transmitter, Section 2.4.3, Loop Test.

Frequency Output Test This test requires the transmitter to produce a desired frequency output. This outputmust be between 1 and 10,000 Hz. See the instruction manual entitled Using the SMARTFAMILY Interface 268 with the Micro Motion Remote Flow Transmitter, Section 2.4.3,Loop Test.

4 to 20 mA Output Trim This feature allows adjustment of the analog output against a high accuracy externalstandard. See the instruction manual entitled Using the SMART FAMILY Interface 268with the Micro Motion Remote Flow Transmitter, Section 3.9.1, 4 to 20 mA Trim.

22

The RFT9729 is used in conjunction with a Micro Motion flow sensor to provide flow in-formation. Therefore, many of the trouble-shooting checks pertain only to the sensor.Other tests are performed with the 268.

3.6.1 Trouble-shooting the

RFT9729

The RFT9729 can be used with 9-wire sensors with up to 1000 feet of cable or with 7-wire sensors with up to 500 feet of cable. Terminals 12, 22, and 18 are internally con-nected. No jumpers are required. Refer to the Sensor Instruction Manual for detailed wir-

ing instructions.

3.6.1.1 Wiring

Resistance checks are made by removing the terminal strip from the terminal block andprobing the corresponding terminals with the probes of a digital voltmeter. Wiringproblems are often incorrectly diagnosed as a faulty sensor. The following should alwaysbe checked when the RFT9729 is first used:

1. Proper cable; use of shielded pairs.2. Proper wire termination.

a. Wires on correct terminals.b. Wires making good connections with terminal strip.c. Wires making good connections at the sensor butt-splices or terminal strip.d. Wi~es properly connected at any intermediate terminal junction.

OUtPIJt wiring should be checked for proper connection. A 250 ohm minimum, 1000 ohmmaximum load resistance must be present on the 4 to 20 mA output loop to enable com-munic:ations with the 268.

The RFT9712 integrates the incoming position detector signal. The integrated signal canbe measured on test point 3TP1 for the left signal and 3TP2 for the right signal. The drivecontrol voltage may also be measured on test point 3TP4. See Table 1 for RFT9712specifications. See Figure 3-1 for test point locations.
