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.

2.1 Precautions

2.1.1 General notes

WARNING!

When you install the device, obey the conditions in the EC-Type Examination certificate. These conditions include:

•

The special conditions for safe use.

•

The Essential Health and Safety Requirements.

DANGER!

This installation must agree with EN 60079-14: Electrical installations in hazardous areas.

2.1.2 Electrostatic discharge

DANGER!

Risk of electrostatic discharge from the blue plastic sun cover, the Drop antenna and the flange plate protection (if the Drop antenna has this option). Make sure that all personnel and equipment are correctly grounded.

INSTALLATION 2

Figure 2-1: ESD warning sticker (below the device nameplate)

1 Text: Plastic Parts 2 Text: Warning! Potential electrostatic hazard - see instructions

Take the necessary antistatic precautions if you:

• handle,

• install or

• use

the device in potentially explosive atmospheres. Do not install in a location (near to ventilation systems, for example) where the electrostatic charge can increase.

2.1.3 Special conditions

OPTIWAVE 8300 C

WARNING!

Aluminium housing: Possible source of ignition in a potentially explosive atmosphere.

The housing is made of either aluminium alloy or stainless steel. If the device has an aluminium alloy housing, make sure that iron/steel objects do not hit or rub against the device.

2.2 Operating conditions

The allowable ambient temperature and corresponding flange temperature range for the device depends on the ATEX equipment category and temperature classes marked on the nameplate.

2.2.1 Ambient and flange temperature

The ATEX equipment category and temperature class give the ambient temperature and related flange temperature ranges for the device.

WARNING!

The gasket temperature must not be more or less than the approved limits.
