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

– 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.
