Rosemount TankRadar RexChapter 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.

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 depart-ment 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 measure-ments” 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



June 2008

• 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 com-puter can be connected to an FCU or to the TankMaster PC in order to further process measured data (level, temperature, pres-sure 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.

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

1-2



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 con-nection at the outside of the FCU box.

1.5.4 Field bus check

• Use a shielded twisted pair cable with an area of at least 0.50 mm2 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 mm2.

Table 1-1: Recommended wiring length

• Connect the shield to terminal 1 or 4.

• Connect ground cable to terminal 1 or 4.

1.6.4 Power supply

• Do not use external power supply when the modem is connected to the USB port. The USB interface itself supports power to the FBM 2180 modem.

• Check if there is water at the bottom of the tank.

1.9.2 Visual check

• Free space below the RTG. Normally girders and pipes are not allowed in the radar beam. If there are disturbing objects below the antenna, the effect on the current measurement must be carefully evaluated.

• Check that waveguide, closing and antenna are mounted correctly and take appropriate actions in order to replace broken parts.


• Diameter of the manhole and the socket height. The socket must not be higher than 330 mm.

• Note the distance X (mm) between the tank wall and the center of the RTG. It will be used for calculations of the clearance angle below the antenna.

1.9.4 Free space requirements

• Check the Clearance Angle plumbline tankwall (arctan X/R). If the clearance angle is less than 15°, the RTG must be inclined away from the wall.
