3.3 Supplementary cleaning proceduresThe VEGADIF 85 is also available in the version "Oil, grease and silicone-free". These instruments have passed through a special cleaningproceduretoremoveoil,greaseandpaint-wettingimpair-ment substances (PWIS).Thecleaningiscarriedoutonallwettedpartsaswellasonsurfacesaccessible from outside. To keep the purity level, the instruments are immediately packed in plastic foil after the cleaning process. The purity level remains as long as the instrument is kept in the closed original packaging.

Caution:The VEGADIF 85 in this version may not be used in oxygen applica-tions. For this purpose, instruments are available in the special ver-sion "Oil and grease-free for oxygen applications".

3.4 Packaging, transport and storageYourinstrumentwasprotectedbypackagingduringtransport.Itscapacity to handle normal loads during transport is assured by a test based on ISO 4180.The packaging of standard instruments consists of environment-friendly, recyclable cardboard. For special versions, PE foam or PE foil is also used. Dispose of the packaging material via specialised recycling companies.

Caution:Instruments for oxygen applications are sealed in PE foil and provided withalabel"Oxygen!UsenoOil".Removethisfoiljustbeforemount-ingtheinstrument!Seeinstructionunder"Mounting".

Transport must be carried out in due consideration of the notes on the transport packaging. Nonobservance of these instructions can cause damage to the device.

The delivery must be checked for completeness and possible transit damage immediately at receipt. Ascertained transit damage or con-cealeddefectsmustbeappropriatelydealtwith.

Up to the time of installation, the packages must be left closed and stored according to the orientation and storage markings on the outside.Unlessotherwiseindicated,thepackagesmustbestoredonlyunderthefollowingconditions:

• Not in the open• Dry and dust free• Not exposed to corrosive media• Protected against solar radiation• Avoiding mechanical shock and vibration

4.1 General instructionsMake sure before mounting that all parts of the instrument exposed to the process are suitable for the existing process conditions.These are mainly:

• Active measuring component• Processfitting• Process seal

Process conditions in particular are:

• Process pressure• Process temperature• Chemical properties of the medium• AbrasionandmechanicalinfluencesYoucanfinddetailedinformationontheprocessconditionsinchapter"Technical data"aswellasonthetypelabel.

The instrument is suitable for standard and extended ambient condi-tions acc. to IEC/EN 61010-1.

Protectyourinstrumentagainstmoistureingressthroughthefollowingmeasures:

• Use a suitable connection cable (see chapter "Connecting to power supply")

• Tighten the cable gland or plug connector• Whenmountinghorizontally,turnthehousingsothatthecable

5.2 ConnectingThe voltage supply and signal output are connected via the spring-loaded terminals in the housing.Connection to the display and adjustment module or to the interface adapter is carried out via contact pins in the housing.

Information:The terminal block is pluggable and can be removed from the electronics.Todothis,lifttheterminalblockwithasmallscrewdriverand pull it out. When reinserting the terminal block, you should hear it snap in.

Proceedasfollows:1. Unscrewthehousinglid2. If a display and adjustment module is installed, remove it by turn-

10.1 MaintenanceIf the device is used properly, no special maintenance is required in normal operation.

Insomeapplications,productbuilduponthediaphragmcaninfluencethe measuring result. Depending on the sensor and application, take precautions to ensure that heavy buildup, and especially a hardening thereof, is avoided.

The cleaning helps that the type label and markings on the instrument are visible.Takenoteofthefollowing:

• Useonlycleaningagentswhichdonotcorrodethehousings,typelabel and seals

• Use only cleaning methods corresponding to the housing protec-tion rating

10.2 Diagnosis memoryThe instrument has several memories available for diagnostic pur-poses. The data remain there even in case of voltage interruption.

Up to 100,000 measured values can be stored in the sensor in a ring memory.Eachentrycontainsdate/timeaswellastherespectivemeasured value.Depending on the instrument version, values that can be stored are for example:

• Level• Process pressure• Differentialpressure• Static pressure• Percentage value• Scaled values• Current output• Lin. percent• Measuring cell temperature• Electronics temperature

When the instrument is shipped, the measured value memory is ac-tive and stores pressure value and measuring cell temperature every 10s,withelectronicdifferentialpressurealsothestaticpressure.TherequestedvaluesandrecordingconditionsaresetviaaPCwithPACTware/DTMorthecontrolsystemwithEDD.Dataarethusreadout and also reset.
