4.3.2Cable entries
The Rosemount 2460 housing has nine M20 x 1.5 and two M25 x 1.5 entries.
Connections must be made in accordance with local or plant electrical
codes.
Make sure that unused cable entries are properly sealed to prevent moisture
or other contamination from entering the terminal board compartment of
the electronics housing.
NOTICE
Thread sealing (PTFE) tape or paste on male threads of conduit is required to
provide a water/dust tight conduit seal and to meet the required degree of
ingress protection as well as to enable future removal of the plug/gland.
Use the enclosed metal plugs to seal unused cable entries in order to achieve
required level of ingress protection. The plastic plugs mounted at delivery
are not sufficient as seal.
4.3.3Power supply
The Rosemount 2460 System Hub accepts supply voltage 100 - 250 Vac
(50/60 Hz) and 24 - 48 Vdc.
Note
The Rosemount 2460 is polarity insensitive for DC voltage input.
4.3.4Cable selection for power supply
Appropriate cross sectional area of wires must be used in order to prevent a

5.3.2Installation procedure
Installation of a Rosemount 2460 System Hub in a Rosemount Tank Gauging
system includes the following basic steps:
Procedure
1. Ensure that a plan is available for all tanks and devices with tag
names, communication addresses, number of temperature elements
and other data that is needed for a system setup.
2. In case devices from other vendors will be connected see the
Rosemount 2460 Reference Manual for more information.
3. Make sure that the Rosemount 2460 is properly wired and up and
running. Check that the Power LED is on and the Status LED indicates
normal operation.
4. (Redundancy). Make sure that the two system hubs are properly
wired as described in Wiring. See also Figure 4-16.
Note
Note that configuration of redundant Rosemount 2460 is supported
by TankMaster 6.D0 and higher versions.
5. Ensure that the TankMaster WinSetup configuration program is up
and running.
6. In TankMaster WinSetup, setup the appropriate protocol channel
the TankMaster host PC. This step will ensure that communication
between the TankMaster PC and the Rosemount 2460 is established.
7. In TankMaster WinSetup, start the device installation wizard and
configure the system hub:
a) In the WinSetup workspace, click the right mouse button on
the Devices folder and select Install new.
(2)
in
b) Specify device type (2460) and name tag.
c) Check that the correct communication channel is enabled
and verify communication with the TankMaster host
computer.
d) Verify that the Host ports and Field ports are using the right
protocols for communication with TankMaster work stations
or other host systems, and with field devices such as the
Rosemount 2410 Tank Hub and the Rosemount 5900S Radar
Level Gauge.
(2) See the Rosemount Tank Gauging System Configuration Manual for more
information on how to configure communication protocol channels.

e) Configure the tank database. See configuration examples
that illustrate how the tank databases of the Rosemount
2460 and the Rosemount 2410 are related to each other in
Tank databases of the Rosemount 2460 and the Rosemount
2410.
f) (Redundancy). Perform a redundancy configuration in case
the system has a pair of redundant system hubs. This is
included as part of the installation wizard. See Redundancy
configuration for more information.
g) Finish the installation wizard and verify that the system hub
appears in the Rosemount TankMaster workspace. Now the
Rosemount 2460 will be able to communicate with the host
system and collect data from field devices.

5.3.3Tank databases of the Rosemount 2460 and the Rosemount 2410
In a typical Rosemount Tank Gauging system, a Rosemount 2460 System
Hub collects measurement data from a number of tanks via one or more
Rosemount 2410 Tank Hubs. For proper communication with the control
room PC and the Rosemount TankMaster operator’s interface, Modbus
addresses need to be assigned to the field devices on the tank. These
addresses are stored in the system hub’s and tank hub’s tank databases.
In the tank hub’s database, the Rosemount 2240S Temperature Transmitter
and the Rosemount 2230 Graphical Field Display (and other non-level
devices) are handled as a single Auxiliary Tank Device (ATD). Two Modbus
addresses are used for each tank, one for the level gauge and one for the
ATD.
The ATD includes any supported non-level device such as the Rosemount
2240S Multi-Input Temperature Transmitter and the Rosemount 2230
Graphical Field Display. Other devices such as the Rosemount 3051S
Pressure Transmitter may also be included in the ATD. The ATD address
represents all these devices. Each position in the Rosemount 2460 tank
database represents one tank.
In case the level gauge is a Rosemount 5900S 2-in-1, you will need to
configure two level device addresses for the Rosemount 5900S gauge. See
the Rosemount Tank Gauging System Configuration Manual (Document No.
00809-0300-5100) for a detailed description of how to configure the tank
database with a Rosemount 5900S 2-in-1.
One Rosemount 2410 Tank Hub for each tank
In this example a Rosemount 2460 System Hub is connected to two tanks,
each of which has a separate Rosemount 2410 Tank Hub.
Each tank has a Rosemount 5900S Radar Level Gauge, a Rosemount 2240S
Multi-Input Temperature Transmitter, and a Rosemount 2230 Graphical
Field Display. The Modbus address configuration is summarized in Table 5-1.

In this example a Rosemount 2460 System Hub is connected to a
Rosemount 2410 Tank Hub that serves three tanks. The temperature device
on tank 1 has the same Modbus address as the tank hub itself. The other
temperature devices on tank 2 and 3 have separate Modbus addresses.
Figure 5-4 shows an example of a system with a Rosemount 2460 System
Hub connected to a Rosemount 2410 Tank Hub. The Rosemount 2410
collects measurement data from three tanks. Each tank is equipped with a
Rosemount 5408 Radar Level Transmitter, a Rosemount 2240S Temperature
Transmitter, and a Rosemount 2230 Graphical Field Display. The Modbus
address configuration is summarized in Table 5-2.

In the tank database of the Rosemount 2410 Tank hub, the Rosemount
2240S temperature transmitter and the Rosemount 2230 display are
grouped into an Auxiliary Tank Device (ATD). The ATD Modbus address has
to be stored in the Temperature Device address field in the tank database of
the Rosemount 2460 System Hub as illustrated in Figure 5-5. The Modbus
addresses of the level devices must also be stored in both the 2410 and the
2460 tank databases.

Take-over criteria
There may be situations when you would like the passive device to take over
as the active device even if no fail-over criteria is fulfilled. For example, in
case the active device does not respond to Host requests, the passive device
may take over and become the active device. The Active doesn’t reply onHost port option does not work if the Primary and Backup system hubs are
wired to separate host ports which is the case when, for example, using the
RS232 communication interface.
Passive device communication
In case the Primary and Backup system hubs are connected to different ports
on the host system, the same Modbus address can be used for
communication with the two system hubs. Then there is no need to use
individual Modbus addresses for the Primary and Backup devices. When
communicating with a host system via RS232 interface, separate host ports
must be used, and the Allow Passive device to reply on common Modbusaddress option needs to be enabled.

6.1Start-up procedure
When the system hub is starting up, the LEDs are lit up and turned off in a
certain order to indicate proper operation. In case an error is detected
during the start-up procedure the red LED remains turned on.
Start-up:
1. All LEDs are turned on
2. Within 0.5 seconds the yellow (Status) LED is turned off.
3. When the start-up procedure is finished, the red (error) LED is turned
off. In case an error is detected during the start-up procedure, the
error LED will start blinking according to the appropriate error code.
4. The green (power) LED remains lit when the system hub is powered
on.
6.2Runtime operation
After the start-up procedure is finished the system hub enters runtime
mode.
The red Error LED will be turned off. If an error occurs, the LED will start to
blink.
In runtime mode the yellow status LED will blink at a rate given by the
current operational mode.
