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.

Chapter 1 Checks and Adjustments
1. 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.
Rosemount TankRadar Rex
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.
1-1
Rosemount TankRadar Rex
Chapter 1 Checks and Adjustments
• 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.
Commissioning Manual
308011En, Ed.2/Rev.B
June 2008
• 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 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.
1.5.2 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.
Commissioning Manual
308011En, Ed.2/Rev.B
June 2008
1.5.3 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.
1.5.4 Field bus check
Rosemount TankRadar Rex
Chapter 1 Checks and Adjustments
• Use a shielded twisted pair cable with an area of at least 0.50 mm
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.
1.5.5 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.
1.5.6 Software
• Note if redundant FCUs are used.
• Note the FCU program version.

To view the FCU program version:
1 Select the FCU icon in the TankMaster WinSetup workspace.
2 Click the right mouse button and choose the Properties option.
3 Select the Communication tab.

1.6 FBM 2180 checklist
1.6.1 FBM information
• Note the name and version of each FBM.
1.6.2 Visual check
• Note if the FBM is installed outdoors or in the control room.
• Check if there is anything in the surroundings which may disturb
the communication such as electromagnetic fields like radiators,
big motors and transformers.
1.6.3 Field bus check
• Check that the TRL/2 bus is connected to socket 2 and 3. Use
twisted and shielded single pair cable with minimum cross sec-
tional area 0.50 mm

1.7 Communication overview
Make a simple drawing showing all tanks and installed units, see Figure

Tank Gauges, Data Acquisition Units, Field Communication Units, Field
Bus Modems and system master. Try to provide as much detail as
possible. A complete view of the system including TankMaster WinOpi
and host computers should be provided, including information on which
Rex units the host computer is connected to.

1.8.2 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.

1.8.3 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.
Note! The G value is defined as positive if the Tank Reference point is located
above the RTG Reference point.

• 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.

1.13.5 Calibration
Normally a minor adjustment of the Calibration Distance parameter is
needed in order to fine tune the gauge to match the manual hand dip
value. It is recommended that the Rex gauge is calibrated when the tank
is not full or empty and when there are no movements in the tank.
To calibrate a Rex gauge do the following:
1 Select the Transmitter icon in the WinSetup workspace.
2 Click the right mouse button and choose the Properties option.
3 Select the RTG Geometry tab.
4 Type a new value in the Calibration Distance field and click the
OK button.
