1.1 Scope of the document
These instructions are applicable only to the explosion-protection version of the radar level
transmitter. For all other data, use the Quick Start and Handbook. If you do not have these
documents, please contact the nearest office or download them from the manufacturer's
internet site.
1.2 Device description
This device is a 2-wire level transmitter that uses FMCW (Frequency-Modulated Continuous
Wave) radar technology. It measures the level, distance, volume, mass and flow rate of liquids,
liquid gases, pastes and slurries. It is suitable for installation on storage tanks, process tanks
and stilling wells. Measurements are displayed via a DTM (device type manager) for remote
communication or an optional integrated display screen with wizard-driven setup and online
help functions.
The level transmitter is approved for use in potentially explosive atmospheres when equipped
with the appropriate options.

2.1 Precautions
2.1.1 General notes
WARNING!
When you install the device, obey the conditions in the EU-Type Examination certificate. These
conditions include:
• The special conditions for safe use.
• The Essential Health and Safety Requirements.
The certificate is given on the DVD-ROM supplied with the device. You can also download the
certificate from our internet site.
DANGER!
This installation must agree with EN 60079-14: Explosive atmospheres
– Part 14: Electrical
installations design, selection and erection.
DANGER!
Devices with the PTFE Wave Horn antenna option contain a PTFE boundary wall between the
process and the signal converter. Do not use the device in the process if the PTFE part is not
resistant to corrosion by the tank product.
Devices with the PP Wave Horn antenna option contain a PP boundary wall between the process
and the signal converter. Do not use the device in the process if the PP part is not resistant to
corrosion by the tank product.

2.1.2 Electrostatic discharge
Do not install in a location where the electrostatic charge can increase. This includes:
•locations near ventilation systems,
•locations where there is a risk of an increase in electrostatic charge caused by compressed
air and dust,
•locations near machines that use friction,
•locations near systems that apply electrons as a spray (e.g. near electrostatic painting
systems), and
•locations near other machines and systems that can have large electrostatic charges.
DANGER!
Risk of electrostatic discharge from the painted surfaces of the aluminium housing and the Wave
Horn and Wave-Stick antennas made of PP or PTFE.
DANGER!
Take the necessary antistatic precautions if:
• you handle the device in potentially explosive atmospheres,
• you install the device in potentially explosive atmospheres or
• you use the device in potentially explosive atmospheres.
Install the device correctly to prevent electrostatic discharge. Make sure that all equipment is
correctly grounded.
Make sure that the housing and adjacent objects do not rub together.
If dirt collects on the device, clean it with a damp cloth.

2.1.3 Optional purging system
The purging system is supplied as an option for devices that have Metallic Horn antennas with a
minimum flange size of DN150.
The pressure of the fluid put into in the purging system must not be more than 6 barg.
Connection and operation of the purging connection are the responsibility of the user. The
operator is also responsible for selection of a suitable fluid to purge the device.
If the tank is installed in Zone 0 or Zone 1, make sure that the purging fluid temperature is not
more than 80% of the ignition temperature of the tank contents. The purging fluid temperature
must be between the minimum and maximum limits for the gasket (for more data, refer to the
handbook) and the type of antenna (for more data, refer to
Ambient and flange temperature on
page 12).
If the tank is installed in Zone 2 or if there is no hazardous atmosphere, the purging fluid
temperature must be between the minimum and maximum limits for the gasket (for more data,
refer to the handbook) and the type of antenna (for more data, refer to
Ambient and flange
temperature
on page 12).
Figure 2-2: Optional purging system
1 G¼threaded connection for purging system (the plug is supplied by the manufacturer)
INFORMATION!
If delivered with the device, the purging connection is plugged with a G 1/4 screw and engaged on
a minimum of 5 threads.
WARNING!
If the G 1/4 screw is removed from the purging connection, make sure that the installation
agrees with the Ex requirements for the purging system.

2.1.4 Optional heating/cooling system
The heating/cooling system is supplied as an option for devices that have Metallic Horn antennas
with a minimum flange size of DN150.
The operating pressure of the heating/cooling system must not be more than 6 barg. The
process pressure must not be more than 2 barg.
If the tank is installed in Zone 0 or Zone 1, make sure that the temperature of the fluid in the
heating/cooling system is not more than 80% of the ignition temperature of the tank contents.
The temperature of the fluid in the the heating/cooling system must be between the minimum
and maximum limits for the gasket (for more data, refer to the handbook) and the type of
antenna (for more data, refer to
Ambient and flange temperature on page 12).

For more data, refer to the table for Ex ia, Ex ia tb and Ex ic devices in the "Ambient and flange
temperature" section.

WARNING!
Equipmentcategory1/2D,2D,3DorEPLDa/Db,Db, Dc: Ex ia, Ex ia tb and Ex ic devices only

If the ambient and flange temperatures of the device are not more than values given in the table
for Ex ia, Ex ia tb and Ex ic devices, the surface temperature of the housing (compact or remote
version) will not be more than +90
° C / +194 ° F. In these conditions, the maximum surface
temperature of other parts (process connection etc.) can be more than the maximum housing
surface temperature, but it will not be more than the process temperature.

3.2.1 How to open the terminal compartment
WARNING!
• De-energize the circuit.
• Use the applicable cable glands for the cable entry openings in the housing (M20×1.5 or
½ NPT). For the cable entry size, refer to the device nameplate.
• If ambient temperature >65 ° C / >149 ° F, use heat-resistant cables, cable glands and cable
entry plugs certified for continuous operation above +80
° C / +176 ° F.
WARNING!
If dirt collects on the housing, clean the device with a damp cloth before you remove the terminal
compartment cover.
