WARNING
Failure to follow safe installation and servicing guidelines could
result in death or serious injury.
Ensure only qualified personnel perform the installation.
Use the equipment only as specified in this manual. Failure to do so
may impair the protection provided by the equipment.
Do not perform any service other than those contained in this
manual unless you are qualified.
To prevent ignition of flammable or combustible atmospheres,
disconnect power before servicing.
Substitution of components may impair Intrinsic Safety.
WARNING
Explosions could result in death or serious injury
Verify that the operating atmosphere of the transmitter is consistent
with the appropriate hazardous locations certifications.
Before connecting a handheld communicator in an explosive
atmosphere, ensure the instruments are installed in accordance with
intrinsically safe or non-incendive field wiring practices.
Do not remove the gauge cover in explosive atmospheres when the
circuit is alive.
WARNING
High voltage that may be present on leads could cause electrical
shock.
Avoid contact with the leads and terminals.
Ensure the mains power to the device is off and the lines to any other
external power source are disconnected or not powered while wiring
the device.
WARNING

2.2 Getting started
2.2.1 Start up a Rosemount Tank Gauging system
To start up a Rosemount Tank Gauging system do the following:
Procedure
1. Install the TankMaster software on the control room PC.
2. Prepare the start-up by recording the information that will be
needed for configuration of the various devices as described in
the Rosemount Tank Gauging System Configuration Manual.
3. Connect the Rosemount 2460 System Hub to the TankMaster
PC. The system hub may be connected via Modbus TCP, a
Rosemount 2180 Field Bus Modem, or directly via RS232 or
RS485 interface.
4. Connect the Rosemount 2410 Tank Hub to the Rosemount
2460 System Hub.
5. Connect the field devices, such as a Rosemount 5900S Radar
Level Gauge and a Rosemount 2240S Multi-input Temperature
Transmitter, to the Rosemount 2410 Tank Hub via the
Tankbus.
6. Configure the Rosemount 2460 System Hub (if included in
the system) by using the TankMaster WinSetup configuration
software.
7. Configure the Rosemount 2410 Tank Hub by using the
TankMaster WinSetup configuration software.
8. Configure field devices, such as the Rosemount 5900S and
the Rosemount 2240S, by using the TankMaster WinSetup
configuration software.

4 Sensor installation
4.1 Installation considerations
A Multiple Spot Temperature sensor (MST) and Water Level Sensor
(WLS), such as Rosemount 565, 566, or 765, must be installed on the
tank before installing the Rosemount 2240S Multi-input Temperature
Transmitter.
The sensor is normally anchored to the bottom of the tank by
attaching a weight at the end of the tube. A tank expands when it is
filled or warmed up, causing the roof to move slightly upwards. The
weight has a shackle which allows the tube to follow the expansion.
Multiple Spot Temperature sensor
•Be careful with the flexible protection tube
•Temperature and Water Level Sensors should be located as far
away as possible from heating coils and mixers.
•In case the flexible tube is damaged, please contact Emerson
Automation Solutions/Rosemount Tank Gauging.
•Do not attempt to fix or rebuild the temperature sensor since this
may cause serious malfunctions
Water Level Sensor
•Handle the Water Level Sensor carefully
•Leave the sensor protection on until the final positioning in the
tank
4.2 Multiple Spot Temperature sensor
A Multiple Spot Temperature sensor (MST) typically measures the
temperature with a number of Pt100 elements placed at different
heights to provide a temperature profile and average temperature of
the product. The spot elements are placed in a flexible gas tight tube
made of stainless steel which can be anchored to the tank bottom.
Up to 16 Pt100 temperature elements can be connected to a
Rosemount 2240S Multi-input Temperature Transmitter.
