1.2 Main hazards

1.2.1 Hazards from hot and/or aggressive gases and/or high pressure

The transmitter/receiver unit is fitted directly on the gas-carrying duct. On equipment with

low hazard potential (no danger to health, ambient pressure, low temperatures), the

installation or removal can be performed while the equipment is in operation providing the

valid regulations and equipment safety notices are observed and suitable protective

measures are taken.

1.2.2 Hazards through electrical equipment

The FW300-EX measuring system is operational equipment for use in industrial high-

voltage current plants.

1.2.3 Hazards through laser beam

1.2.4 Hazards from explosive or flammable gases

The measurement system FW300-EX may be used only in accordance with the relevant

specification in hazardous areas.



Install/remove transmitter/receiver unit and reflector on equipment with

hazard potential (gases detrimental to health, hot, aggressive or explosive

gases or gas/dust mixtures, higher internal duct pressure) only when the

equipment is at a standstill.

WARNING:Danger through mains voltage



Disconnect mains lines before working on mains connections or parts car-

rying mains voltage.



Refit any contact protection removed before switching the mains voltage

back on again.

WARNING:Hazards through laser beam

 Never look directly into the beam path

 Do not point the laser beam at persons



Pay attention to laser beam reflections.

WARNING:Hazards from explosive or flammable gases



p. 10, §1.3).



Use the measurement system only within the temperature limits as speci-

fied in this operating instructions as well as on the nameplate.

The maximum values must not be exceeded also for brief periods.

 Do not install sender/receiver unit and rotating reflector in lines, tanks or

other installation areas where explosive gas and / or dust mixtures may be

present.

For devices that are used in hazardous areas:

● Installation, commissioning, maintenance and testing may be performed

only by experienced persons who have the knowledge of the rules and

regulations for hazardous areas, particularly:

–Types of protection

Correct use



Use the device only as described in these Operating Instructions. The manufacturer

bears no responsibility for any other use.



Observe all measures necessary for conservation of value, e.g. for maintenance and

inspection and/or transport and storage.

 Do not remove, add or modify any components to or on the device unless described and

specified in the official manufacturer information. Otherwise

– the device could become dangerous

– the manufacturer’s warranty becomes void

– invalidate the approval for use in hazardous areas.

 Do not use damaged components or parts.

Special local conditions



Observe and adhere the local valid laws, regulations and plant-internal operating

instructions, especially on systems with an increased hazard potential (pressure pipes,

explosion protection zones).

Retention of documents

Operating Instructions belonging to the measuring system as well as equipment

documentation:



Keep at site for reference at all times



Pass it on to any new owner.

1.5.2 Safety information and protective measures

Protection devices

Behavior during purge air failure

The purge air supply serves to protect optical subassemblies fitted on the duct against hot

or aggressive gases. Leave the supply switched on when the equipment is at a standstill.

Optical subassemblies can be severely damaged in a short time if the purge air supply

fails.

NOTICE:

Suitable protection devices and safety equipment for persons must be

available according to the respective hazard potential and be used by the

personnel.

NOTICE:

The user must ensure that:



The purge air supply runs reliably and continuously.



Failure of the purge air supply is immediately detected (e.g. by using

pressure monitors)



Optical subassemblies are removed from the duct if the purge air supply

fails and the duct opening is closed off (e.g. with a flange cover)

Preventive measures for operating safety

Recognizing malfunctions

Every deviation from normal operation is to be regarded as a serious indication of a

functional impairment. These are, amongst others:

● Warning displays (e.g. heavy contamination)

● Large drifts in measured results

● Increased power input

● Higher temperatures of system parts

● Monitoring devices triggering

● Smells or smoke emission

Avoiding damage

NOTICE:

The user must ensure that:



Neither failures nor erroneous measurements can lead to operational

states that can cause damage or become dangerous



The specified maintenance and inspection tasks are carried out regularly

by qualified, experienced personnel.

NOTICE:

The operator must ensure the following to avoid malfunctions that can

indirectly or directly lead to injuries to persons or material damage:



The responsible maintenance personnel are present at any time and as

fast as possible



The maintenance personnel are adequately qualified to react correctly to

malfunctions of the measuring system and any resulting operational

interruptions (e.g. when used for measurement and control purposes)



The malfunctioning equipment is switched off immediately in case of doubt

and that switching off does not cause collateral malfunctions.
