Specific FCC Requirements (USA only)

Rosemount TankRadar Rex generates and uses radio frequency energy.

If it is not installed and used properly, that is, in strict accordance with the manufacturer´s instructions, it may violate FCC regulations on radio frequency emission.

Rosemount TankRadar Rex has been FCC certified under test conditions which assume a metallic tank. Installation on a non-metallic tank is not certified, and is not allowed.

The FCC certificate for Rosemount TankRadar Rex requires that the tank is closed as far as emitted radio energy is concerned. Tanks with open manholes, external-floating-roof tanks without still-pipes etc. are not covered by the certificate.

Checks and Adjustments

1.1

General

Commissioning a Rex system aims at checking the mechanical and electrical installations.

It includes calibrations and adjustments in order to achieve high accuracy and reliability. The communication between various TRL/2 and

Rex units is checked, and necessary backups of database files etc. are created. It also includes checking that the installations are done according to safety regulations.

This manual provides brief descriptions of most of the items in the Check

List for Rosemount TankRadar Rex. The checklist is used as a guide when commissioning a Rex system. When you need more information on a certain item in the check list, read the corresponding section in this chapter for further information.

Note!

Before commissioning a Rex system, always read the Rex Installation

Manual (Document No. 308014), Rex Special Safety Instruction

(Document No. 308016), and Rex Safety Manual (SIL2; Document No.

308020).

1.2

Preparations

•

•

•

•

•

•

Check that the equipment is undamaged and that it corresponds to the specifications. Note the following information:

Delivery no. the system number provided by the project department at Emerson Process Management/Rosemount Tank

Gauging.

Name and location of plant.

Service agency: the name of the local agency responsible for the installation.

Engineer responsible for the commissioning, and the date when commissioning was concluded.

Note the tank distances needed for installation and configuration

of the Rosemount Tank Radar Rex system. See “Tank measurements” on page 1-8 for illustrations of the different tank distances.

Note the addresses to be used for the communication between the connected devices (RTG, DAU, FCU) and TankMaster.

•

Check that the correct hardware parts are installed.

Make sure that you bring appropriate tools and instruments.

Install TankMaster.

1.3

Tank Interior Conditions

Look for objects which may produce disturbing echoes like girders, heating coils or agitators. Disturbing objects can severely affect the accuracy of the measurements.

1.4

System Composition

•

•

•

Enter the following information about the system:

Number of tanks.

System Master. There may be several units acting as master at different occasions. The system is supervised by TankMaster

(WinOpi). A portable service PC may temporarily be connected to an FCU when system service is required (WinSetup). A host computer can be connected to an FCU or to the TankMaster PC in order to further process measured data (level, temperature, pressure etc.).

The number of FCUs, FBMs, RTGs and DAUs.

1.5

FCU checklist

1.5.1

1.5.2

FCU information

Note the name, Unit ID and address of each FCU.

This will facilitate the configuration of the Rex system. Check that the

Unit ID placed at the cover of the FCU box and on the

FCU motherboard match.

Note the address which will be used for the different FCUs.

Figure 1-1. Position of Unit ID on FCU cover.

•

•

Visual check

The FCU is not intrinsically safe. It must therefore be installed in a nonhazardous area.

Weather protection: make a note whether the FCU is placed in a control room or another weather protected location.

Electrical check

Power supply. Check that the switch inside the FCU box is set to the correct value. 230 V is the default value. If 115 V is used, the box on the nameplate «Mark box if re-wired for 115 VAC» shall be marked.

Grounding: if there is no protective ground in the mains supply

cable, the FCU should be externally grounded via the ground connection at the outside of the FCU box.

•

•

•

Field bus check

Use a shielded twisted pair cable with an area of at least 0.50 mm

2 for the TRL/2 bus.

Shielded cables are required in order to avoid crosstalk if the cables run alongside and also to avoid other disturbances. The field bus shield should be connected to ground at the FCU only.

Contact Emerson Process Management/Rosemount Tank

Gauging for further instructions.

Note the distance if there are two fieldbuses running in parallel.

•

•

Group bus check

Note the number of group buses that are used. The FCU can be configured with two, three or four group bus ports.

Note whether the group bus communicates via the RS-232C or the TRL/2 bus interface. By replacing the FCM board with an FCI board, RS-485 communication can also be used.

•

•

Software

Note if redundant FCUs are used.

Note the FCU program version.

To view the FCU program version:

Electrical check

RTG Power Supply: The 3900 Rex transmitter accepts 100-240

VAC, 50-60 Hz and max. 80 W. The built-in Transformer Rectifier

Card (TRC) automatically adapts to the connected supply voltage.

Optional: low voltage AC/DC versions (34-70 VAC/48-99 VDC).

Grounding: Certain national regulations requires protective grounding of enclosure, see Special Safety Instruction for further information. Special Safety Instruction is delivered together with each Rex transmitter. Check with Emerson Process Management/

Rosemount Tank Gauging and/or local authorities if necessary.

Field bus continuity: Measure the resistance between leads 3 and 4. Resistance values between 1 and 20

Ω indicate that the field bus cable is undamaged and correctly connected.

Field bus shield grounding: Check that the field bus shield is connected to ground at the FCU only, and not at the RTG.

Tank measurements

Tank reference distance, R. The R distance is defined as the distance between the dipping datum point (zero level) and the tank

reference point.

RTG reference distance, G. G is the distance between the tank

reference point (hand dip nozzle) and the RTG reference point.

The RTG reference point is underneath the RTG flange, see Figure 1-5.

Minimum level distance, C. C is the distance between the dip-

ping datum point (zero level) and the bottom of the tank.

Note the distance (mm) from max product level to RTG reference point.

The G value is defined as positive if the Tank Reference point is located above the RTG Reference point.

Tank Information

• Note what type of pressure flange that is used: 150, 300 or 600

PSI. For non-standard antennas this information is needed in order to configure the Tank Connection Length (TCL). See the

TankMaster Winsetup User’s Guide for more information on TCL configuration. For standard antennas the TCL is automatically configured and does not need to be changed.

• Make a note if the RTG is equipped with a ball valve.

Check that the verification pin is aligned towards the flangemark,

see Figure 1-15.

Check that the waveguide, housing and foam plug are installed according to the instructions in the Installation Manual, chapter 10.

Verification pin and deflection plate with calibration ring

The verification pin should be placed at 2000 ±500 mm from the

RTG Reference Point.

Measure the distance from the top of the bottom plug to the bot-

tom of the tank, see Figure 1-16. This value will be used for the

calibration of the RTG:

• Zero level at tank bottom: adjust the Calibration distance value until the displayed level (at the calibration ring) is equal

to the distance from calibration ring to tank bottom (see Figure 1-16).

• Zero level at calibration ring: adjust the Calibration distance value so the displayed level is equal to zero.

Выполняет высокоточные измерения уровня в направляющих трубах резервуаров с понтоном или плавающей крышей. Труба используется в качестве волновода для радарного луча. Допустимый диаметр труб от 5″ до 12″. Благодаря запатентованному режиму распространения радарной волны исключается влияние загрязнений стенок направляющей трубы на точность измерений.
