Safety

Correct use in explosion-hazard zones


Correct use of the device includes theobservance of all specifications in theOperating Instructions for "RVM/UA-2Module BASICS" and "RVM/UA-2Module ATEX".

Any addition or different application,above and beyond the correct use inaccordance with these instructions, isdeemed as incorrect use.

WARNING!

Danger due to incorrect use!– Use the flow monitor only

within the stipulated per-formance limits

– Do not subject the flowmonitor to severe tempera-ture fluctuations

– Do not use the flow monitorwith quick-acting valves

– Do not use the flow monitorwith solenoid valves

– Do not subject the flowmonitor to vibrations

– Do not subject the flowmonitor to pressure surges

– Do not use the flow monitorwith media containingsolids or abrasives

– Only use the flow monitorwith media previouslyapproved by the manufac-turer

– Do not use the flow monitoras the sole monitoringdevice to prevent dan-gerous conditions

– Do not install the flow mon-itor as a load bearing partwithin a pipeline system

Safety

Correct use in explosion-hazard zones


– The flow monitor may onlybe installed in explosion-hazard zones if:– the labeling on the flow

monitor,– the labeling on the

switch unit installed onthe flow monitor,

– and the informationcontained in theaccompanying docu-mentation (OperatingInstructions "RVM/UA-2 Module BASICS"and Operating Instruc-tions "RVM/UA-2Module ATEX"),authorize such installa-tion and operation.

– Planning and design ofequipment, protective sys-tems and components isthe responsibility of thefacility operator

– The potential impact, incase of an explosion, mustbe taken into account bythe facility operator.

– The facility operator isresponsible for the substi-tution, or the reduction ofthe quantity of substances,which may cause an explo-sive atmosphere

All claims for damages due to incorrectuse are excluded.

Incorrect use of the flow monitor mayresult in dangerous conditions.

2.3 Special precautionsfor use in explosion-hazard zones

For opera-tion in explosion-hazard zones, allvalid provisions for safety, accidentprevention and environmental protec-tion must be complied with.

Operation


8 TroubleshootingThe procedures in case of malfunctionare described in Chapter 7, "RVM/UA-2 Module BASICS". All safety- andhazard warnings, contained in Chapter7, "RVM/UA-2 Module BASICS", mustbe followed. Additionally, for operationin explosion-hazard zones, all validprovisions for safety, accident preven-tion and environmental protection mustbe complied with.

Troubleshooting


9 MaintenanceMaintenance procedures aredescribed in Chapter 8, "RVM/UA-2Module BASICS". All safety- andhazard warnings, contained in Chapter8, "RVM/UA-2 Module BASICS", mustbe followed. For operation in explo-sion-hazard zones, all valid provisionsfor safety, accident prevention andenvironmental protection must be com-plied with. Maintenance proceduresmay only be performed outside theexplosion-hazard zone.

DANGER!

Danger to life if maintenanceprocedures are performed inthe explosion-hazard zone– Maintenance procedures

may only be performed out-side the explosion-hazardzone

12 AnnexThe required tools are specified inChapter 11.3 "Tools" of the OperatingInstructions for "RVM/UA-2 ModuleBASICS".

In explosion-hazard zones, tools whichmay cause sparks, are not to beemployed. These tools may only beemployed when there is no potentiallyexplosive atmosphere present.

The use of steel tools, of any kind, isprohibited in hazard zone 1, if there isa risk of explosion due to substancesin explosion hazard group IIC (inaccordance with IEC/TR3 60079-20),(for example, acetylene, hydrogen).
