1.1 Scope of the document
These instructions are applicable only to the explosion-protection version of the radar level
transmitter. 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 an FMCW radar level meter designed for use with the BM 26 Advanced (a magnetic
level indicator or MLI) or a bypass chamber. If the device is used with an MLI, it measures the
distance to the float. If the device is used with a bypass chamber, it measures the distance to the
surface of the liquid. Radar is a non-contact technology. Measurements are displayed via a DTM
(device type manager) for remote communication.
The level meter is approved for use in potentially explosive atmospheres when equipped with the
appropriate options.
1.3 Standards and approvals

The information in these supplementary instructions only contains the data applicable to
explosion protection. The technical data for the non-Ex version in the Handbook shall be valid in
its current version, provided that it is not rendered invalid or replaced by these supplementary
instructions.
WARNING!
Installation, commissioning and maintenance may only be carried out by "Personnel trained in
explosion protection".
DANGER!

•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. adjacent to 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. There is
also a risk of electrostatic discharge if the stainless steel housing has painted surfaces.
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.

(volume, V ≤2000 cm³), use approved flameproof cable glands (M20×1.5 or ½NPT). The cable
glands must have a test certificate that agrees with EN 60079-1. Obey the instructions given
on the test certificates. Make sure that that the tightening capacity of the cable entry is
applicable to the diameter of the electrical wire.
•If you use conduits to connect electrical wires to the terminals in the flameproof terminal
compartment, obey the instructions that follow. Make sure that the conduits are correctly
attached and the flameproof compartment is sealed. The flameproof joint must have a
minimum thread length of 8 mm / 0.32¨. The conduits must have a test certificate that agrees
with EN 60079-1. Use conduit stopping boxes that agree with precautions given in the test
certificate and data in standards related to the installation of the conduit.
•If you connect electrical wires to the terminals in the dustproof terminal compartment, use
approved flameproof cable glands (M20×1.5 or ½NPT). The cable glands must have a test
certificate that agrees with EN 60079-31. Obey the instructions given on the test certificates.
Make sure that that the tightening capacity of the cable entry is applicable to the diameter of
the electrical wire.
Electrical wiring
•The electrical wiring must agree with the applicable standards (e.g. EN 60079-14 / VDE 0165)
and the maximum process temperature.

In normal operational conditions, no maintenance is necessary. If it is necessary, maintenance
must be done by approved personnel (the manufacturer or personnel approved by the
manufacturer).
We recommend that you do regular inspections:
•Do a check of the housing cable entries and electrical wires for damage and corrosion.
•Make sure that the process connection and the signal converter are not clogged if there is a
risk that dust will collect in recesses.
•Make sure that the process connection is sealed.
•Make sure that the device is included in process pressure tests.

5.3 How to remove the device
The installation and removal of the device or the signal converter is a task for approved
personnel (operator, fitter, electrician etc.). If you must change the signal converter or all the
device, refer to the procedures in the handbook. It is not necessary to remove the matching
element from the process connection.
If you must do work in a hazardous location:
•Before you open the flameproof or dustproof terminal compartment, de-energize the device.
•Make sure that all electrical wires are isolated from the ground. This is also applicable to
Protective Earth (PE), Functional earth (FE) and equipotential bonding conductors.
•Apply grease to dry housing cover seals after you open the terminal compartment. Use a
multi-purpose grease (e.g. NONTRIBOS®Li EP2).
•Close the housing cover immediately after maintenance. Make sure that the housing is
sealed.
When you attach the signal converter, use a 5 mm Allen wrench to tighten the hex head screws
on the matching element to 8 N·m/5.9lbf·ft. If you changed the device, use a 6 mm Allen
wrench to tighten the hex head screws of the Metaglas®component on the pipe connection to
20 N·m / 14.8 lbf·ft.
