Fig. 3: Functional principle - Plate capacitor1 Distance between the electrode surfaces2 Size of the electrode surfaces3 Type of dielectric between the electrodes
The probe and the vessel wall are the capacitor plates. The measured product is the dielectric. Due to the higher dielectric constant of the product compared to air, the capacitance increases as the probe is gradually covered.The capacitance change is converted by the electronics module into a switching command.
VEGACAP 63 is a compact instrument, i.e. it can be operated without external evaluation system. The integrated electronics evaluates the level signal and outputs a switching signal. With this switching signal, aconnecteddevicecanbeoperateddirectly(e.g.awarningsystem,apumpetc.).Thedataforpowersupplyarespecifiedinchapter"Technical data".
3.3 OperationThe probe can be adapted to the dielectric constant of the product directly on the electronics module.A switching command can be triggered when the probe is covered or laid bare.Ontheelectronicsmoduleyouwillfindthefollowingdisplayandadjustment elements:
• Signallampforindicationoftheswitchingcondition(green/red)• Potentiometer for switching point adaptation• DIL switch for measuring range selection• DIL switch for mode adjustment
3.4 Packaging, transport and storageYour instrument was protected by packaging during transport. Its capacity 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.

4.1 General instructionsMake sure that all parts of the instrument coming in direct contact with the process, especially the sensor element, process seal and processfitting,aresuitablefortheexistingprocessconditions,suchas process pressure, process temperature as well as the chemical properties of the medium.Youcanfindthespecificationsinchapter"Technical data"andonthenameplate.
In general the level switch can be mounted in any position. The instru-ment must be mounted in such a way that the probe is at the height of the requested switching point.
Before beginning the welding work, remove the electronics module from the sensor. By doing this, you avoid damage to the electronics through inductive coupling.Ground the probe before welding directly on the rod or cable.
With threaded versions, the housing must not be used to screw in the instrument. Applying tightening forces on the housing can damage its internal parts.Use the hexagon for screwing in.
Usetherecommendedcables(seechapter"Connecting to power supply")andtightenthecablegland.You can give your instrument additional protection against moisture penetration by leading the connection cable downward in front of the cableentry.Rainandcondensationwatercanthusdrainoff.Thisap-plies mainly to outdoor mounting as well as installation in areas where highhumidityisexpected(e.g.throughcleaningprocesses)oroncooled or heated vessels.

Theprocessfittingmustbesealedifthereisgaugeorlowpressureinthe vessel. Before use, check if the seal material is resistant against the measured product and the process temperature.Themax.permissiblepressureisspecifiedinchapter"Technical data"oronthetypelabelofthesensor.
Metal vesselMake sure that the mechanical connection of the probe to the vessel iselectricallyconductivetoensuresufficientgrounding.Use conductive seals, such as those made of copper or lead, etc. Insulatingmeasures,suchascoveringthethreadwithTeflontape,can interrupt the necessary electrical connection with metal vessels. For this reason, ground the probe on the vessel or use a conductive seal material.Non-conductive vesselsIn non-conductive vessels, e.g. plastic tanks, the second pole of the capacitor must be provided separately, e.g. in the form of a concentric tube.
Metric threadsIn the case of instrument housings with metric thread, the cable glands are screwed in at the factory. They are sealed with plastic plugs as transport protection.You have to remove these plugs before electrical connection.
NPT threadIn the case of instrument housings with self-sealing NPT threads, it is not possible to have the cable entries screwed in at the factory. The free openings for the cable glands are therefore covered with red dust protection caps as transport protection.Prior to setup you have to replace these protective caps with ap-proved cable glands or close the openings with suitable blind plugs.
4.2 Mounting instructionsDuetotheeffectsofagitators,equipmentvibrationorsimilar,thelevelswitch can be subjected to strong lateral forces. For this reason, do not use an overly long electrode for VEGACAP 63, but check if you canmountashortlevelswitchonthesideofthevesselinhorizontalposition.Extreme vibration caused by the system, e.g. due to agitators or turbulenceinthevesselfromfluidisation,cancausetheprobeofVEGACAP 63 to vibrate in resonance. If a longer rod version is neces-sary, you can secure the probe by fastening a suitable brace or guy directly above the end of the rod.
Iftheinstrumentismountedinthefillingstream,unwantedfalsemeasurement signals can be generated. For this reason, mount the instrument at a position in the vessel where no disturbances, e.g. from fillingopenings,agitators,etc.,canoccur.This applies particularly to instrument versions with a longer probe.

5.1 Preparing the connectionAlways keep in mind the following safety instructions:
Warning:Connect only in the complete absence of line voltage.
• The electrical connection must only be carried out by trained personnel authorised by the plant operator.
• Alwaysswitchoffpowersupply,beforeconnectingordisconnect-ing the instrument.
Note:Install a separating facility for the instrument which is easy to access. Theseparatingfacilitymustbemarkedfortheinstrument(IEC/EN61010).
Connect mains voltage according to the connection diagrams. Take note of the general installation regulations. The electronics module CP60C is designed in protection class I. To maintain this protection class, it is absolutely necessary that the ground conductor be con-nected to the internal ground conductor terminal. Take note of the corresponding installation regulations for Ex applications.Thedataforpowersupplyarespecifiedinchapter"Technical data".
The instrument is connected with standard three-wire cable without screen. If electromagnetic interference is expected which is above the test values of EN 61326 for industrial areas, screened cable should be used.Use cable with round cross-section. A cable outer diameter of 5…9mm(0.2…0.35in)ensuresthesealeffectofthecablegland.Ifyouareusingcablewithadifferentdiameterorcross-section,exchange the seal or use a suitable cable gland.
5.2 Connection procedureWith Ex instruments, the housing cover may only be opened if there is no explosive atmosphere present.
Proceed as follows:1. Unscrew the housing lid2. Loosen compression nut of the cable gland and remove blind

We recommend connecting VEGACAP 63 in such a way that the switching circuit is open when there is a level signal, line break or failure(safestate).The contactless electronic switch is always shown in non-operative condition.
Warning:The instrument must not be operated without an intermediately connected load, because the electronics would be destroyed if con-nected directly to the mains. It is not suitable for connection to low voltage PLC inputs.
Examples for typical applications:
• Loadresistanceat24VDC:88…1800Ω• Rated power, relay 253 V AC: > 2.5 VA• Rated power, relay 24 V AC: > 0.5 VA
For direct control of relays, contactors, magnet valves, warning lights, horns etc.Domestic current is temporarily lowered below 1 mA after switching offtheloadsothatcontactors,whoseholdingcurrentislowerthanthe constant domestic current of the electronics, are reliably switched off.
