1 GENERAL SAFETY INFORMATION
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 manufacturers internet
site.
INFORMATION!
The information in this manual only contains the data applicable to explosion protection. The
technical data in the installation and operating manual for the non-Ex version shall be valid in its
current version, provided that they are not rendered invalid or are replaced by this manual.
WARNING!
Installation, commissioning and maintenance may only be carried out by "Personnel trained in
explosion protection".
1.2 Device description
This device is a 2-wire level transmitter that uses FMCW (Frequency-Modulated Continuous
Wave) radar technology. It measures level, volume, distance to surface, and reflectivity of
liquids, pastes, slurries and solid particles, granulates and powders.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 on an optional integrated display screen
with wizard-driven setup and online help functions.
OPTIWAVE 8300 C
The level transmitter is approved for use in potentially explosive atmospheres when equipped
with the appropriate options.
Ex ia-approved devices can also be equipped with an external sensor to measure process
temperature, pressure, etc.
1.3 Standards and approvals
DANGER!
In compliance with European Directive 94/9/EC (ATEX 100a), the ATEX version of the device
described in these Supplementary Instructions conforms to European Standards EN 600790:2006, EN 60079-1:2007, EN 60079-11:2007, EN 61241-0:2006, EN 61241-1:2004, EN 6124111:2006 and EN 60079-26:2007. The Ex ia and Ex d [ia] versions are certified for use in hazardous
areas by the KEMA Quality B.V. under KEMA 04ATEX1218 X.
WARNING!
Carefully read the ATEX approval certificate. Obey the boundary conditions.
