Installations in Europe

2.2 Configuration, calibration, and characterization

To comply with CENELEC standards for hazardous area installations in Europe, adhere to the following CENELEC conditions for safe use.

Cable glands and conduit seals

• Use 3/4"-14 NPT cable glands or conduit fittings, rated flameproof for EEx d IIC areas and certified by an authorized test station. Flameproof glands supplied by Micro Motion meet these requirements.

• Conduit openings that are not used should be sealed with blanking plugs of type PLG 2.

• For installation in a nonhazardous area, cable glands or conduit fittings that do not carry a flameproof rating are acceptable.

Potential equalization

To achiev e potential equalization, the RFT9739 ground conductor should be connected to the appropriate ground terminals within the hazardous area, using a potential equalizing line.

Output wiring

Nonintrinsically-safe connections between the RFT9739 and other devices may be made or equal to 250 V.

The following information explains the differences among configuration, calibration, and characterization. Certain parameters might require

configuration

even when

only

to devices that maintain a voltage less than

calibration

is not necessary.

Configuration parameters

measurement units, flow direction, damping values, slug flow parameters, and span values for the milliamp and frequency outputs. If requested at time of order, the transmitter is configured at the factory according to customer specifications.

Calibration

density, and temperature. Field calibration is optional.

Characterization

density, and temperature directly into transmitter memory. Calibration factors can be found on the sensor serial number tag and on the certificate that is shipped with the sensor.

For configuration, calibration, or characterization procedures, see one of the following communications manuals:

Using the HART Communicator with Micro Motion Transmitters

•

Using ProLink Software with Micro Motion Transmitters

•

Using Modbus Protocol with Micro Motion Transmitters

•

You can also use Fisher-Rosemount™ Asset Management Solutions (AMS) software for configuration, calibration, and characterization. For more information, see the AMS on-line help.

2.3 Switch settings

Security modes

Switches 1 through 10 on the electronics module control the following transmitter functions:

• Baud rate

• Stop bits and parity

• Data bits, communication protocol, and physical layer

• mA outputs

• Zeroing method

• Write-protection of transmitter configuration Switches 1 through 10 are illustrated in

Figure 2-2

, and described in the

following sections. Normally, switch settings do not require adjustment.

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 zero button and, if the transmitter has a display, the Scroll and Reset knobs

• Totalizer reset, with flow, using digital communications

• Totalizer reset, with flow, using the Scroll and Reset knobs, if the transmitter has a display

• Totalizer control, with zero flow, using digital communications

• Totalizer control, with zero flow, using the Scroll and Reset knobs, if the transmitter has a display

• Ability to change configuration or calibration factors

Pow er-Supply and

Security mode 8

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 optional display reads, "SECURITY BREACH; SENSOR OK"

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

Table 6-2

, page 56.)

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 perform a master reset, see instructions in

To verify the transmitter is in security mode 8:

• If the transmitter has a display, use the Scroll knob to scroll through

process variable screens to event register screens. If event register screens appear, the transmitter is in security mode 8. For more information about using the Scroll knob and transmitter display, see

Section 6.2

, page 51.

• If the transmitter does not have a display:

1. Configure the transmitter.

2. Wait until the diagnostic LED blinks ON once per second.

3. Move switch 1, 2, or 3 to the OFF position.

4. If the diagnostic LED blinks ON 4 times per second, the transmitter is in security mode 8.

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 communication 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, and the RFT9739 has a display, an error message will appear on the 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 switches as instructed in

Table 2-2

, page 10. With switches 1 through 6, the user can set baud rate; stop bits and parity; data bits, protocol, and physical layer. The default settings are HART protocol, over RS-485, at 1200 baud, with 1 stop bit and odd parity.

Pow er-Supply and

Sensor Wiring

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 65.

3 Transmitter Mounting

3.1 General guidelines

Follow these guidelines when installing the field-mount RFT9739 transmitter:

• Locate the transmitter where it is accessible for service and calibration.

• In hazardous areas, install the transmitter in a location that is specified

Section 2.1

• Total length of cable from the sensor to the transmitter must not exceed 1000 feet (300 meters).

• Locate the transmitter where the ambient temperature remains between –22 and 131°F (–30 and 55°C). If the transmitter has a display, the display might become difficult to read below 14°F (–10°C).

• Mount the transmitter to a stable, flat surface or instrument pole.

• The cover of the transmitter housing requires 11½ inches (292 mm) clearance for removal. If the transmitter has a display, the cover requires 13 3/16 inches (335 mm) clearance.

The base of the transmitter has three ¾-inch NPT female conduit openings (see keep the transmitter watertight.

, page 3.

Figure 3-1

, next page), which must remain sealed to

CAUTION

Failure to seal transmitter housing could cause a short circuit, which w ould result i n measuremen t err or or flowmeter failure.

Pow er-Supply and

Sensor Wiring

To avoid risk of condensation or excessive moisture entering the transmitter housing, fully seal all conduit openings when installing the transmitter.

• Install conduit that allows a complete seal with the conduit openings.

• If possible, orient the transmitter with its conduit openings pointed downward. If this is not possible, seal the conduit to prevent condensation and other moisture from entering the housing.

• To comply with CENELEC standards for hazardous area installations in Europe:

Use cable glands or conduit fittings rated flameproof for EEx d IIC areas and certified by an authorized test station. Flameproof glands supplied by Micro Motion meet these requirements.

Conduit openings that are not used should be sealed with blanking plugs of type PLG 2.

For installation in a nonhazardous area, cable glands or conduit fittings that do not carry a flameproof rating are acceptable.

• If the transmitter has a display, the display will be right-side-up only if the transmitter is oriented with its conduit openings pointed downward.
