2.5.4
MEASUR.MODE
The device uses the dielectric constant (εr)
of the tank contents to monitor level. In
direct mode (if the dielectric constant is
high), the level signal is a reflection on the
surface of the tank contents. If the dielectric
constant is low, the device uses TBF mode.
The device in TBF mode uses the radar
reflection on the bottom of the tank (the
signal goes through the tank contents). The
tank must have a flat bottom for the device
to operate correctly in TBF mode. This
menu item is set by default to "Direct" for
tank contents with an εr >1.8. If εr is very low
(<1.6), use "TBF Full". If εr is low (εr =
1.5...1.7), use "TBF Partial" mode. "TBF
Partial" is an automatic mode that lets the
device make a selection between "Direct
mode and "TBF" mode. If you use "TBF Full"
or "TBF Partial", enter the dielectric
constant in menu item 2.5.3 Er PRODUCT.

Multiple reflections will cause the device to
display smaller level readings. Objects in
the tank, sharp corners, installation of the
device on a large nozzle or at the centre of a
dome roof, and low dielectric products (εr =
1.8...5) can cause multiple reflections. A
very calm surface or a tank with a small
convex or flat roof can also cause multiple
reflections.
If this function is in operation, the device
looks for the first signal peak below the

8 TECHNICAL DATA
OPTIWAVE 7400-24 C
8.1 Measuring principle
A radar signal is emitted via an antenna, reflected from the product surface and received after a
time t. The radar principle used is FMCW (Frequency Modulated Continuous Wave).
The FMCW-radar transmits a high frequency signal whose frequency increases linearly during
the measurement phase (called the frequency sweep). The signal is emitted, reflected on the
measuring surface and received with a time delay, t. Delay time, t=2d/c, where d is the distance
to the product surface and c is the speed of light in the gas above the product.
For further signal processing the difference Δf is calculated from the actual transmitted
frequency and the received frequency. The difference is directly proportional to the distance. A
large frequency difference corresponds to a large distance and vice versa. The frequency
difference Δf is transformed via a Fourier transformation (FFT) into a frequency spectrum and
then the distance is calculated from the spectrum. The level results from the difference between
the tank height and the measured distance.

DESCRIPTION OF HART INTERFACE 9
OPTIWAVE 7400-24 C
9.1 General description
The HART® Protocol is an open digital communication protocol for industry. It is free to use by
anyone. It is included in the software embedded in signal converters of HART-compatible
devices.
There are 2 classes of devices which support the HART® Protocol: operating devices and field
devices. There are 2 classes of operating devices (Master): PC-supported workstations (Primary
Master) and manual control units (Secondary Master). These can be used in control centres and
other locations. HART® field devices include sensors, converters and actuators. Field devices
include 2-wire and 4-wire devices, and also intrinsically-safe versions for use in hazardous
areas.
There are 2 primary operation modes for HART-compatible devices: point-to-point mode and
multi-drop mode.
If the device is used in point-to-point mode, the HART® Protocol uses the Bell 202 Frequency
Shift Keying (FSK) standard to put a digital signal on top of the 4...20 mA signal. The connected
device sends and receives digital signals that agree with the HART® Protocol, and sends analog
signals at the same time. Only 1 device can be connected to the signal cable.
If the device is used in multi-drop mode, the network only uses a digital signal that agrees with
the HART® Protocol. The loop current is set to 4 mA. You can connect a maximum of 15 devices
to the signal cable.
An FSK or HART® modem is included in field devices and manual control units. It is necessary to
have an external modem for PC-supported workstations. The external modem is connected to
the serial interface.

OPTIWAVE 7400-24 C
9.3 Connection variants
The signal converter is a 2-wire device with 4...20 mA current output and HART® interface.
• Multi-Drop Mode is supported
In a Multi-Drop communication system, more than 1 device is connected to a common
transmission cable.
• Burst Mode is not supported
There are two ways of using the HART® communication:
• as Point-to-Point connection and
• as Multi-Drop connection with 2-wire connection.
9.3.1 Point-to-Point connection - analogue / digital mode
Point-to-Point connection between the signal converter and the HART® Master.
The current output of the device is passive.
Also.
9.3.2 Multi-Drop connection (2-wire connection)
For an illustration of multi-drop networks.
9.4 HART® device variables
The HART® dynamic variables PV (Primary Variable), SV (Secondary Variable), TV (Third Variable)
and QV (Fourth Variable) can be assigned to any of the device variables.
The HART® dynamic variable PV is always connected to the HART® current output which is, for
example, assigned to level measurement.
9.5 Field Communicator 475 (FC 475)
The Field Communicator is a hand terminal from Emerson Process Management that is
designed to configure HART® and Foundation Fieldbus devices. Device Descriptions (DDs) are
used to integrate different devices into the Field Communicator.
9.5.1 Installation
CAUTION!
The Field Communicator cannot be used to correctly configure, operate or read data from the
device unless the Device Description (DD) file is installed.
System and software requirements for the Field Communicator
• System card that includes the "Easy Upgrade Option"
• Field Communicator Easy Upgrade Programming Utility
• HART® Device Description file

DESCRIPTION OF HART INTERFACE 9
For more data, refer to the Field Communicator User’s Manual.
9.5.2 Operation
INFORMATION!
The Field Communicator will not give you access to the service menu. A simulation is only
possible for current outputs.
The Field Communicator and the device's local display use almost the same procedures to
operate the signal converter. The online help for each menu item refers to the function number
given to each menu item on the local device display. Protection of settings is the same as on the
device's local display.
The Field Communicator always saves a complete configuration for communication with AMS.
For more data, refer to HART® menu tree for Basic-DD on page 118.
9.6 Asset Management Solutions (AMS)
The Asset Management Solutions Device Manager (AMS) is a PC program from Emerson
Process Management which is designed to configure and manage HART®, PROFIBUS and
Foundation-Fieldbus devices. Device Descriptions (DDs) are used to integrate different devices
into the AMS.
9.6.1 Installation
Please read the README.TXT file in the Installation Kit.
If the Device Description has not been installed at this time, install the Installation Kit HART®
AMS. This .EXE file is given on the DVD-ROM supplied with the device. You can also download the
file from our website.
For installation data, refer to the "AMS Intelligent Device Manager Books Online" section "Basic
AMS Functionality > Device Configurations > Installing Device Types > Procedures > Install
device types from media".
9.6.2 Operation
INFORMATION!
For more data, refer to HART® menu tree for AMS on page 119.
9.6.3 Parameter for the basic configuration
Due to AMS requirements and conventions, there are differences when operating the signal
converter with AMS and operating using the local keyboard. The service menu parameters are
not supported and simulation is only possible for current outputs. The online help for each
parameter contains its function number as a reference to the local device display.

10.4 Glossary
Dead zone
Non-measurement zone.
Dielectric constant
An electrical property of the product to be measured used in Radar
measurement. Also known as εr, DK and relative permittivity. Defines the
strength of the wave reflected back to the device's signal converter.
Distance
The distance from the face of flange to the level (1 product) or the surface
of the top product (2 or more products). See the diagrams at the end of this
section.
Drop antenna
A new generation of antenna made of PP or PTFE. It has an ellipsoidal
shape for a more precise emission of radar signals.
DTM
Device Type Manager. A driver for use in the PACTware™ program. All data
and functions of the device are included in it.
Electromagnetic compatibility Defines how much a device influences or is influenced by other devices that
generate electromagnetic fields during operation. Refer to European
standard EN 61326-1 for further details.
FMCW
Frequency-modulated continuous-wave radar technology. The signal is
continuously present, but the frequency is modulated, usually in
successive linear ramps over time (frequency sweeps).
Hazardous area
An area with a potentially explosive atmosphere. Trained personnel can
install and use a device in this area. The device must be ordered with the
appropriate options. The device requires approvals (ATEX, IECEx, FM, CSA,
NEPSI etc.) related to site specifications. You can find more data about
hazardous areas in the Ex Manuals and Ex Certificates of Compliance.
Horn (cone) antenna
A common antenna for most applications. It is used for the controlled
emission and collection of radar signals.
