2. Function
TheAirSafePMusesahighendopticalmeasurementsystemthatisembeddedinthesensor.Theairows
throughthemeasuringdevicewhichcountstheparticlesanddenestheirsize.Therawmeasurementis
processed by a unique algorithm which enables continuous and accurate measurement for the different
sizesofparticlesaswellasclassicationofAorEdustfractions(alsoknownasinhalableandrespirable
fractions).
2.1 Particles size / glossary
PM describe all dust particles smaller than the mentioned size.
Example: PM1 include all dust particles smaller than 1 µm
PM2.5 include all dust particles smaller than 2.5 µm
PM4.5 include all dust particles smaller than 4.25 µm
PM10 include all dust particles smaller than 10 µm
TSP refer to “Total suspended particles” with is equal
to all dust particles equal or smaller than 100 µm
European standard EN 481 also separate dust in 2 fractions:
•E dust: The respirable fraction – Particles equal or smaller than 100 µm
•A dust: The inhalable fraction – Particles equal or smaller than 4.25 µm
2.2 Compliance
This sensor comply with TRGS 900 and EN 481.

3. Safety
The sensor was designed, built and tested for safety and is shipped in this condition. Components within
thesuppliedsystemcouldbehazardousifnotunpacked,installed,connectedandcommissionedby
authorisedqualiedpersons.Alloperatinginstructionsmustberead,andunderstood,beforehandlingthe
system.Failuretodosowillcausethewarrantytoberevoked.
3.1 Normal use
•Themeasuringsystemmayonlybeinstalledindoor,inworkplace,productionarea,storage
areas,restareas,rooms,openspacesandinindustrialworkareas.
•Only original spare parts and accessories from ENVEA must be used.
3.2 Identicationofhazards
Possiblehazards,whenusingthemeasuringsystem,aremarkedbythefollowingsymbols:
Warning!
•Thissymbolisesasituationwherepersonalsafetyisatriskifusedinanimpropermanner.
Attention!
•This symbolises the possible damage to the system, if used in an improper manner.
3.3 Occupational and operational safety
•The measuring system must be installed by trained and authorised personnel only.
•Protective equipment must be worn to avoid injuries caused by possible sharp edges on the
measuring device.
•Whenusingacablewithmorethan4cores,unused,opencoresmaycausesparking.Failure
tocomplywiththespeciedconnectionparametersofthecablewillresultinlossofintrinsic
safety. To prevent this, it is mandatory to use a 4-core shielded cable.
Alwaysensurethattheconnectionparametersofthecablearewithinthespecication(Li,Ci).
The shield of the cable must not be connected to the housing under any circumstances.
•Improper mechanical stress (e.g. torsion) can cause damage to the device. To avoid this, the
device should always be installed in accordance with all the instructions in the operating manual.
The measuring device should also not be exposed to any vibrations if possible.
•Improperuseofthedevicewillresultinahighrisktosystemsafety,thereforethedevicemust
onlybeusedasspeciedintheassociateddocumentation.
•Switchoffthepowersupplyforallmaintenance,cleaningorinspectionworksonthesensoror
on components. Follow the notes of the chapter maintenance.
•Thecomponentsandelectricalconnectionsmustbecheckedfordamagesregularly.Ifadamage
is found, it is to be repaired before further operation of the instruments.

6
3.4 Maintenance
•For maintenance purposes, it is imperative that the device is de-energised and cooled down,
otherwisethereisanincreasedriskofexplosion.
•Beforeworkingonthedeviceoritscomponents,itisessentialtoensurethattheyarede-
energised.Otherwisethereisariskofelectricshock.
•Thecorrecttoolmustbeusedtoopenthedevice,otherwisethereisariskofinjuryandcrushing.
•Before opening the device or its components, it is imperative to ensure that there is no EX zone.
•Duringcleaningworkonthedeviceorintheprocess,thereisanincreasedriskofexplosiondue
to electrostatic discharges and excessive pressures.
3.5 Technical statement
The manufacturer reserves the right to change any technical data concerning technical
developments, without prior notice. If any queries arise, ENVEA will be happy to inform customers
of any possible changes made.
3.6 Reliability
For any additional information concerning product reliability, please contact ENVEA.
3.7 Storage conditions
Observe the following instructions during storage:
•Toensureshockresistance,storeinoriginalpackaging.
•Do not remove protective discs or caps mounted on process connections.
They prevent mechanical damage and contamination to the sealing surfaces.
•Protect from sunlight to avoid impermissibly high surface temperatures.
•Store in a dry and dust-free place.
•Do not store outside.
3.8 Limits of use
To achieve optimum performance and safe operation, the equipment must be operated within the limits
given in this manual. Operation outside these limits can result in damage to the equipment or failure to
achievetheperformancespecied.Thisproductanditsvariantsarenotexplosivezoneapproved.

4. Mounting and installation
TheAirSafePMcanbemountedonanyatsurfaceoronawallusingmountingbrackets(ENVEArecommendto
installthesensorinaatpositionifpossible).Thesensorisdesignedformonitoringambientairinworkplacesin
industriessuchascementplants,foundries,woodworkshops,incinerationplantsorlogisticwarehouses.
The AirSafe PM can be easily mounted to most surfaces and areas:
• In or around process areas
• Storage rooms
• Laboratories
• Breakrooms
• Changing rooms
• Inoraroundofceareas
• Other footfall areas of health and safety exposure concern
• Areas of air quality monitoring requirements
InstalltheAirSafePMasnearaspossibletoairintakes,areasofairmovement,andareasofstaticair/settlement
wherepeoplework.Whenpositionedneartheventilationandltrationapparatus,theAirSafePMcanbeused
tomonitortheeffectivenessoftheventilationandltrationprocess.
Attention!
AirSafe PM can be used only indoors, DO NOT use outdoors.
