7 Product description 3 Product description 3.1 Configuration Scope of deivery Components The scope of deivery encompasses: VEGACAP 27 eve sensor Documentation - this operating instructions manua - if necessary, further documents VEGACAP 27 consists of the foowing components: Housing cover Housing with eectronics Process fitting with eectrode Type abe Fig. 1: VEGACAP 27 - with pastic housing 1 Housing cover 2 Housing with eectronics 3 Process fitting 4 active screen segment 5 active probe The type abe contains the most important data for identification and use of the instrument: Artice number Seria number Technica data Artice numbers, documentation VEGACAP doube reay (DPDT) 7

8 Product description With the seria number, it is possibe to show the deivery data of the instrument via " "VEGA Toos" and "seria number search". In addition to the type abe outside on the instrument, the seria number is aso avaiabe inside the instrument. 3.2 Principe of operation Area of appication Functiona principe VEGACAP 27 is a eve switch with fuy insuated, capacitive eectrode with screen segment and active tip for eve detection. VEGACAP 27 is very rugged and maintenance-free and can be used in a areas of industria process technoogy. Typica appications are overfi and dry run protection. Setup of the instrument is very easy because an adjustment is not necessary. This means that changing products with different dieectric vaues, such as e.g. water and oi or conductive and non-conductive products, do not infuence the settings on the instrument and their switching accuracy. Fuy insuated probes with screen segment ike VEGACAP 27 are preferaby used in conductive, very adhesive iquids. Due to the mechanica construction with screen segment and the active tip, buidup on the probe is compensated. The capacitive measuring principe paces no specia requirements on instaation. Hence, many different appications can be equipped with VEGACAP 27. The instrument can aso be used probem-free in corrosive products. Probe, measured product and vesse wa form an eectrica capacitor. The capacitance is infuenced by three main factors. 8 VEGACAP doube reay (DPDT)

9 Product description Fig. 2: Functiona principe - Pate capacitor 1 Distance between the eectrode surfaces 2 Size of the eectrode surfaces 3 Type of dieectric between the eectrodes The probe and the vesse wa are the capacitor pates. The measured product is the dieectric. Due to the higher dieectric constant (DK vaue) of the product compared to air, the capacitance increases as the probe is graduay covered. The capacitance change is converted by the osciator into a switching command. Suppy VEGACAP 27 is a compact instrument, i.e. it can be operated without externa evauation system. The integrated eectronics evauates the eve signa and outputs a switching signa. With this switching signa, a connected device can be operated directy (e.g. a warning system, a PLC, a pump etc.). You can find data on votage suppy in chapter "Technica data" in the "Suppement". 3.3 Operation The probe can be adapted to the dieectric vaue of the product directy on the eectronics modue. A switching command can be triggered when the probe is covered or aid bare. On the eectronics modue you wi find the foowing indicating and adjustment eements: Contro amp for indication of the switching condition Potentiometer for switching point adaptation (covered) DIL switch for mode adjustment VEGACAP doube reay (DPDT) 9

10 Product description 3.4 Storage and transport Packaging Transport Transport inspection Storage Storage and transport temperature Your instrument was protected by packaging during transport. Its capacity to hande norma oads during transport is assured by a test according to DIN EN The packaging of standard instruments consists of environment-friendy, recycabe cardboard. For specia versions, PE foam or PE foi is aso used. Dispose of the packaging materia via speciaised recycing companies. Transport must be carried out under consideration of the notes on the transport packaging. Nonobservance of these instructions can cause damage to the device. The deivery must be checked for competeness and possibe transit damage immediatey at receipt. Ascertained transit damage or conceaed defects must be appropriatey deat with. Up to the time of instaation, the packages must be eft cosed and stored according to the orientation and storage markings on the outside. Uness otherwise indicated, the packages must be stored ony under the foowing conditions: Not in the open Dry and dust free Not exposed to corrosive media Protected against soar radiation Avoiding mechanica shock and vibration Storage and transport temperature see "Suppement - Technica data - Ambient conditions" Reative humidity % 10 VEGACAP doube reay (DPDT)

11 Mounting 4 Mounting 4.1 Genera instructions Switching point Weding work Handing Moisture In genera the eve switch can be mounted in any position. The instrument must be mounted in such a way that the probe is at the height of the requested switching point. Before beginning with the weding work, remove the osciator out of the sensor. By doing this, you avoid damages ont he eectrode due to inductive coupings. With threaded versions, the housing must not be used to screw the instrument in! Appying tightening force on the housing can damage its rotationa mechanica parts. Use the hexagon for screwing in. Use the recommended cabes (see chapter "Connecting to power suppy") and tighten the cabe gand. You can give your VEGACAP 27 additiona protection against moisture penetration by eading the connection cabe downward in front of the cabe entry. Rain and condensation water can thus drain off. This appies mainy to outdoor mounting, areas where high humidity is expected (e.g. from ceaning processes) or cooed or heated vesses. Fig. 3: Measures against moisture penetration Transport Do not hod VEGACAP 27 on the probe. Especiay with heavy fange versions or ong rod versions, the sensor can be damaged simpy by the weight of the instrument. VEGACAP doube reay (DPDT) 11

12 Mounting Pressure/Vacuum The process fitting must be seaed if there is gauge or ow pressure in the vesse. Before use, check if the sea materia is resistant against the measured product and the process temperature. The max. permissibe pressure is stated in chapter "Technica data" in the "Suppement" or on the type abe of the sensor. 4.2 Mounting instructions Agitators and fuidization Infowing medium Agitators, equipment vibration, etc., can cause the eve switch to be subjected to strong atera forces. For this reason, do not use an overy ong probe for VEGACAP 27, but check if you can mount a short eve switch on the side of the vesse in horizonta position. Extreme vibration caused by the system, e.g. due to agitators or turbuence in the vesse from fuidisation, can cause the probe of VEGACAP 27 to vibrate in resonance. If a onger rod version is necessary, you can secure the probe by fastening a suitabe brace or guy directy above the end of the rod. If VEGACAP 27 is mounted in the fiing stream, unwanted erroneous measurements may resut. Mount VEGACAP 27 at a ocation in the vesse where no disturbing infuence from e.g. fiing openings, agitators, etc. can occur. This appies particuary to instrument versions with a onger probe. 12 VEGACAP doube reay (DPDT)

14 Connecting to power suppy 5 Connecting to power suppy 5.1 Preparing the connection Note safety instructions Seect power suppy Seecting connection cabe Aways keep in mind the foowing safety instructions: Connect ony in the compete absence of ine votage Connect the power suppy according to the foowing diagrams. Osciator CAP E31R is designed in protection cass 1. To maintain this protection cass, it is absoutey necessary that the ground conductor be connected to the interna ground termina. Take note of the genera instaation reguations. As a rue, connect VEGACAP 27 to vesse ground (PA), or in case of pastic vesses, to the next ground potentia. On the side of the housing there is a ground termina between the cabe entries. This connection serves to drain off eectrostatic charges. You can find data on votage suppy in chapter "Technica data" in the "Suppement". VEGACAP 27 is connected with standard cabe with round cross section. An outer cabe diameter of 5 9 mm ( in) ensures the sea effect of the cabe gand. If cabe with a different diameter or wire cross section is used, exchange the sea or use an appropriate cabe connection. Note: When pacing the housing cover, make sure that the inspection gass is above the signa amp of the osciator. 5.2 Wiring pan, singe chamber housing Wiring pan We recommend connecting VEGACAP 27 in such a way that the switching circuit is open when there is a eve signa, ine break or faiure (safe condition). The reays are aways shown in non-operative condition. The two reays (DPDT) work synchronousy. Hence it is possibe to contro aso e.g. a horn and a magnet vave. 14 VEGACAP doube reay (DPDT)

16 Set up 6 Set up 6.1 Genera The numbers in brackets refer to the foowing iustrations. Function/Configuration On the eectronics modue you wi find the foowing indicating and adjustment eements: Potentiometer for switching point adaptation DIL switch for mode adjustment - A/B Contro amp Note: As a rue, aways set the mode with the mode switch (5) before starting setup VEGACAP 27. The switching output wi change if you set the mode switch (5) afterwards. This coud possiby trigger other connected instruments or devices. 6.2 Adjustment eements Fig. 6: Osciator with reay output 1 Type abe 2 Connection terminas 3 Tensie proving ring 4 Contro amp 5 DIL switch for mode adjustment 6 Potentiometer for switching point adaptation 16 VEGACAP doube reay (DPDT)

17 Set up The switching status of the eectronics can be checked with cosed housing (ony pastic housing), see "Function chart". Note: When pacing the housing cover, make sure that the inspection gass is above the signa amp (LED) of the osciator. To adjust VEGACAP 27, oosen first of a the four screws on the upper side of the instrument with a screwdriver and remove the housing cover. Switching point adaptation (6) Mode adjustment (5) You can adapt the switching point to the soid with the potentiometer. The eectronics is adjustment free and an adaption is ony necessry in exceptions. See "Exceptions". With the mode switch you can change the switching condition of the reay. You can set the required mode (A - max. detection or overfi protection, B - min. detection or dry run protection). We recommend connecting according to the quiescent current principe (reay contact deenergizes when the switching point is reached), because the reay aways takes on the same (safe) condition if a faiure is detected or in case of mains faiure. Signa amp (4) Switching point adjustment Contro amp for indication of the switching condition Contro amp on = Reay deenergised The measuring system is immediatey ready for operation. The switching point must no onger be set with VEGACAP 27. The probe has an active tip and a screen segment. Thanks to the screen segment, the so caed standing capacitance, caused by the vesse after instaation of the probe, is mainy compensated. As a defaut setting, the osciator is adjusted to the basic capacitance of the probe. The reay output switching when the active tip is covered (active tip: mm / in) of the eectrode. Changing dieectric vaues of the products, such as e.g. caused in mixing vesses are no probem for the switching accuracy within the active pin. The seection of the eectrode ength is hence very important because the ength of the eectrode determines the switching point. This switching point cannot be shifted on the eectrode. VEGACAP doube reay (DPDT) 17

18 Set up Exceptions Fresh adjustment In exceptions, e.g. in pipeines or if the probe is mounted very cose to the vesse wa, it can happen ath the probe signas aready overfiing (covering) in uncovered condition. In this case, the switching point must be re-adjusted. For adjustment, the vesse must not be fied and the switching point adjustment is aso possibe in dismounted condition. A fresh adjustment is necessary in the foowing cases: for probes with a ength of more than 3 m (9.8 ft) in narrow space instaation conditions with high standing capacitance (e.g. in tubes etc.) after exchange of the osciator Proceed as foows for a fresh adjustment: 1 Make sure that the probe is uncovered. 2 Pierce the cover of the potentiometer (6) with a screwdriver. 3 Turn the beow potentiometer (6) first of a anticockwise (max. 20 turns) unti the contro amp signas "covered". Mode A (overfi protection) = contro amp ights Mode B (dry run protection) = contro amp extinguishes If this condition is aready reached, you can continue with the next step. 4 Turn the potentiometer (6) very sowy (due to the damping) cockwise unti the contro amp signas "uncovered". Mode A (overfi protection) = contro amp extinguishes Mode B (dry run protection) = contro amp ights 5 Turn the potentiometer (6) cockwise according to the foowing chart. 6 The probe is now ready for operation. Sensitivity additiona turns Standard DK vaue >2 = 2 turns very sensitive DK vaue >1.5 = 1 turn Tab. 1: Number of additiona turns for the potentiometer (6) Note: With the measurement of products with very ow dieectric vaues, the number of turns can be reduced up to 1 according to the chart. 18 VEGACAP doube reay (DPDT)

21 Maintenance and faut rectification 7 Maintenance and faut rectification 7.1 Maintenance When used as directed in norma operation, VEGACAP 27 is competey maintenance free. 7.2 Remove interferences Reaction in case of faiures Causes of mafunction Faut rectification 24 hour service hotine The operator of the system is responsibe for taken suitabe measures to remove interferences. VEGACAP 27 offers maximum reiabiity. Nevertheess fauts can occur during operation. These may be caused by the foowing, e.g.: Sensor Process Suppy Signa processing The first measure to be taken is to check the output signa. In many cases, the causes can be determined this way and the fauts rectified. However, if these measures are not successfu, ca the VEGA service hotine in urgent cases under the phone no The hotine is avaiabe to you 7 days a week round-the-cock. Since we offer this service word-wide, the support is ony avaiabe in the Engish anguage. The service is free of charge, ony the standard teephone costs wi be charged. Checking the switching signa? VEGACAP 27 signas "covered" when the vibrating eement is not submerged (overfi protection)? VEGACAP 27 signas "uncovered" when the vibrating eement is submerged (dry run protection) Wrong mode seected à Set the correct mode on the mode switch (A - overfi protection, B - dry run protection). Wiring shoud be carried out according to the quiescent current principe. Suppy votage too ow à Check the power suppy VEGACAP doube reay (DPDT) 21

22 Maintenance and faut rectification Eectronics defective à Press the mode switch (A/B). If the instrument then changes the mode, the instrument may be mechanicay damaged. Shoud the switching function in the correct mode sti be fauty, return the probe for repair. à Push the mode switch. If the probe then does not change the mode, the osciator may be defective. Exchange the osciator. Shortcircuit in the probe, e.g. because of moisture in the housing à Remove the osciator and check the resistance between the marked pug connections according to the foowing iustration. 1 2 C PH 7 1 MW M C M 3 Fig. 21: Check the resistance in the probe 1 Midde pin 2 Variabe capacitor (phase) 3 Capacitor Measure the resistance vaues between the foowing contacts with an ohmmeter (range MOhm). 22 VEGACAP doube reay (DPDT)

23 Maintenance and faut rectification Contact 4 against midde pin (1) The resistor must be 1 MOhm. If the resistor is ower, this means moisture in the housing or a faut in the eectrode insuation. A possibe reason coud be aso a non-insuated eectrode which is used in a conductive (humid) medium. If the resistor is higher or if the connection is interrupted, the reason is mosty a contact error in the adapter pate or a defective resistor due to strong eectrostatic arking. In both cases, the probe must be repaired in our premises. Contact 4 against vesse The eectrica connection between contact 4 and meta vesse (not the mounting boss or probe fange) shoud good. Measure the resistance vaue between contact 4 and vesse with an ohmmeter (range very sma). Shortcircuit (0 3 Ohm) - optimum connection Resistor >3 Ohm - bad connection If the resistance vaue is >3 Ohm, this can be due to corrosion on the thread or fange or the thread was covered e.g. with tefon tape. Check the connection to the vesse. If there is no connection, you can connect a cabe from the outer ground termina to the vesse. Keep in mind that coated fanges must aways be connected via the ground termina to the vesse. Contact 7 against midde pin (1) The resistor must be infinite (>10 MOhm) If the resistor is ower, then moisture can be penetrated or the compensation capacitor or variabe capacitor (phase) is defective. Contact 3 against 4 The resistor must be 1 MOhm. In case of ower vaues, the eectrode insuation is defective or moisture is penetrated into the housing. In case of higher vaues, there is a contacting error in the adapter pate or the resistor is defective. No faut if you cannot find a faut in the probe, then exchange the osciator by a simiar repacement eectronics (if avaiabe). VEGACAP doube reay (DPDT) 23

24 Maintenance and faut rectification If the faut is eiminated after inserting the new osciator, then you have to carry out a fresh adjustment with the new osciator because osciators have certain manufacturing toerances. If the faut sti exists or if no repacement osciator is avaiabe, then you have to return the probe for repair. Reaction after faut rectification Depending on the faiure reason and measures taken, the steps described in chapter "Set up" must be carried out again, if necessary. 7.3 Exchange of the eectronics modue If it is necessary to exchange the osciator, you shoud use an osciator type CAP E31R Proceed as foows: 1 Switch off power suppy 2 Loosen the four screws of the housing cover with a Phiips screwdriver. 3 Remove the housing cover 4 Loosen the screws of the terminas with a Aen wrench. 5 Pu the connection cabes out of the terminas. 6 Loosen the two screws with a Phiips screwdriver. 7 Open the tensie ring on the od osciator and pu out the od osciator. 8 Compare the new osciator with the od one. The type abe of the osciator must correspond to that of the od osciator. 9 Insert the new osciator. 10 Screw in and tighten the two screws with a Phiips screwdriver. 11 Lead the connection cabe through the cabe gand. 12 Insert the wire ends into the open terminas according to the wiring pan and tighten them. 13 Check the hod of the wires in the terminas by ighty puing on them. 14 Turn the cabe gand right back and check the tightness. The sea ring must competey encirce the cabe. 15 Carry out a fresh adjustment. See chapter "Set up, new adjustment". 16 Retighten the housing cover 24 VEGACAP doube reay (DPDT)
