3 Product description 1 Product description 1.1 Function and configuration VEGAVIB compact level switches are used for level detection of powders and granules. The vibrating level switches are piezoelectrically energized and vibrate at their mechanical frequency (VEGAVIB 31 appr. 10 Hz, VEGAVIB 41 and 43 appr. 530 Hz, VEGAVIB 51, 5 and 53 appr. 350 Hz). When the measured product touches the vibrating probe, the vibrating amplitude is damped. An integral electronics detects this damping and triggers a switching command. VEGAVIB 31 tuning fork sensor is suitable for fine-grained solids > 100 g/l, which are not adhesive. Typical products are gypsum, cement, fine granules etc. VEGAVIB series 40 and 50 tuning fork sensors can be used where levels of solids from a density of appr. 0 g/l can be reliably detected. Due to the rod version build-up is virtually avoided. Hence the use in foodstuffs and light products such as e.g. packing chips. Typical products are cement, gypsum, styropor, chalk, flour, cereals, paper scrap, washing powder, plastic granules, feather etc. A pulsed driving signal is responsible for the re-oscillation of the tuning fork after covering and removes residual measured product from the probe. Series 50 instruments are also suitable for the detection of solids in water. 1.

20 Mounting Mounting.1 Mounting instructions VEGAVIB Generally the instruments can be mounted in any position. The instrument must be mounted so that the measuring system (vibrating rod) is at the height of the requested switch point. However VEGAVIB 31 should not be mounted from the bottom. According to the measured product/measurement requirements, installation will vary. Please follow manufacturers instructions. Lateral load Please note that the vibrating element is not subjected to lateral forces. Mount the instrument in a position where no interfering influences occur such as e.g. by stirrers, filling openings etc. This is mainly valid for the instrument types with cable or extension tube (see fig..1). The tuning fork surfaces of VEGAVIB 31 should be in parallel to the product movement so that there is only little resistance by the tuning fork. Stirrers Due to stirrers etc. the level switch can be subjected to strong lateral forces. Hence do not choose a too long extension tube of VEGAVIB 43 and VEGAVIB 53, but check if in this case it is possible to mount a VEGAVIB 41 or VEGAVIB 51 laterally. Filling opening Install so that the vibrating element does not protrude directly into the filling stream. If such an installation place should be necessary, mount a suitable protective sheet above or in front of the vibrating element, e.g. L80 x 8 DIN 108 (see fig.. a). In case of abrasive solids the mounting acc. to fig.. b has proven. In a concave protective sheet build-up is caused avoiding abrasion of the protective sheet. Horizontal installation VEGAVIB can be mounted horizontally to reach a very accurate switch point. However if the switch can differ in a tolerance of some centimeters, we recommend an installation appr. 0 inclined to the bottom so that buildup is avoided (see fig..). Mount VEGAVIB 31 so that the surface of the tuning fork is nearly vertically. a. b. Fig..1 0 Dimensions The dimensions of the vibrating rod or the tuning fork must not be modified. Any modification will destroy the instrument. Fig.. 0 VEGAVIB

21 Mounting Handling The vibrating level switch is a measuring instrument and must be handled with care. Bending of the vibrating element will destroy the instrument. Adjustment fitting Adjustment fittings are available for height adjustment of VEGAVIB 43 and VEGAVIB 53. Please note that the VEGAVIB 53 level switch must not be used in conjunction with the adjustment fitting in pressurized vessels. VEGAVIB 43 can be used in vessels with up to 4 bar pressure. Humidity After installation turn the cable entry of the instrument downwards to avoid humidity penetration. The instrument housing can be rotated by appr On vertically installed electrodes loop the cable to the instrument housing bottom so that rain water and condensation can drain off (see fig..3). Tensile load When using the cable version please note that the max. tensile load of 6000 N must not be exceeded. This danger mainly exists with very heavy solids and large measuring lengths. Fig..3 Build-up On VEGAVIB 31 the surfaces of the tuning fork should be nearly vertical so that build-up is avoided. The position of the tuning fork is marked on the hexagon of VEGAVIB. Hence you can check the position of the tuning fork. When the hexagon is placed to the seal, the thread can be still turned by appr. 1/ turn. This is sufficient to reach the recommended installation position. When the granulation size of the solid is bigger than the min. tuning fork distance (8 mm), parts of the measured product can stick between the tongues of the fork and trigger a faulty function. In this case a tuning fork sensor of series 40 and 50 should be used. Pressure In case of overpressure or low pressure in the vessel, the mounting boss must be sealed on thread. Cover the thread with teflon tape or hemp etc. or use a seal ring. Angle of repose Note when mounting the vibrating rod in the vessel, that angles of repose can occur with solid measurement which can influence the switch point. Select an installation place so that the vibrating probe detects an average value of the angle of repose. According to the position of the filling and emptying opening in the vessel, the installation place of the vibrating probe differs. The vibrating probe must be installed with a distance of d / 6 from the vessel wall to compensate for the measuring error in cylindrical vessels. A min. distance of appr. 40 cm should be maintained (see fig..4). VEGAVIB 1

Due to a fixed coded pin on the Ex-module it is ensured that only Ex-instruments can be inserted. Transparent cover The front plate of VEGATOR can be provided with a lockable transparent cover to avoid unauthorized adjustment. The cover is attached to the instrument. Two additional coded pins are attached to the module to protect the different instrument against interchanging. Plug the attached coded pins into the respective holes on the multipoint connector. The coded pins must be plugged into the following positions: Instrument coding Ex-coding VEGATOR 536 a17 / c7 VEGATOR 536 Ex a17 / c7 c3 VEGATOR 537 a19 / c7 VEGATOR 537 Ex a19 / c7 c3 Module 33 (Ex) VEGAVIB 3

24 Mounting Ex-version Ex and non-ex terminal separation Within the plug-in terminal base a physically separated area exists for Ex connections. Ensure that the separation housing is fitted and secure. Mounting into carriers If you mount your VEGATOR with Ex-approval into a carrier, you have to use a VEGA-Exmodule. Keep a distance of at least 10 mm ( TE) to module cards of other manufacturers. If you intend to install VEGATOR in the complete left position in the carrier, you have to mount a blind cover with at least 0 mm (4 TE) in front of the module for the instrument. VEGATOR 636 Ex signal conditioning instrument Connect the signal conditioning instrument as follows: - Mount the plug-in socket to the carrier rail. - Wire the socket acc. to your requirements, see 3 Electrical connection. - Cover the upper terminals with the supplied covering chamber (see figure). - Plug the supplied coded pin into the appropriate hole. - Connect, if requested, the neighbouring series 600 signal conditioning instrument via the supplied connection plug (L1 and N). - Select mode A or B on the slide switch (top). - Mount VEGATOR 636 Ex to the plug-in socket ( fixing screws).

Wiring plan VEGAVIB Non-contact switch (VIB E40 C, E50 C) The electrical connection must be carried out dependent on the installed oscillator. Connect the mains acc. to the wiring plans on the following pages. Generally connect VEGAVIB to vessel ground (PA) or in plastic vessels with the next earth potential. A thread (screw M4 x 5) is located laterally on the hexagon of the mounting boss. This connection is used to drain off electrostatic charges. For dust-ex-applications or applications acc. to CENELEC the PA-terminal (on the hexagon of the mounting boss) must be connected to the potential equalization line AC L1 N Earth DC or DC Power supply: 0 50 V AC, 50/60 Hz; 0 50 V DC (for further information see technical data) For direct control of relays, contactors, magnet valves, signallers, horns etc. do not operate without connected load (switching in series), as the oscillator will be destroyed when directly connected to mains. Not suitable for connection to low voltage-dcs-inputs The own current is shortly lowered below 1 ma after switching off the load so that contactors holding current which is lower than the currently flowing own current of the electronics can nevertheless be switched off reliably Housing cover Signal lamp (LED) 3 Terminals 4 A/B-switch 5 Potentiometer 6 Instrument housing 7 Cable entry (Pg 13,5) 8 Oscillator 9 Type plate oscillator 7 6 VEGAVIB

By different connection of the consumer (load) PNP or NPN-reaction can be reached. Power supply via the connected VEGATOR signal conditioning instrument (1 36 V DC) (for further information see technical data) The signal lamp in the housing generally lights when the vibrating probe is covered, independent on the mode adjusted in the signal conditioning instrument Note the operating instruction of the signal conditioning instrument. Suitable signal conditioning instruments are stated in the technical data. Floating transistor output (VIB E40 T, E50 T) NPN-reaction PNP-reaction The transistor switches a second voltage source with the same reference potential to the binary input of a DCS or to an electrical load. By different connection of the consumer (load) PNP or NPN-reaction can be reached Power supply: V DC (for further information see following switching examples as well as technical data) VEGAVIB 7

28 Electrical connection NPN-reaction PNP-reaction The transistor switches a second, galvanically isolated voltage source to the binary input of a DCS or to an electrical load. By different connection of the consumer (load) PNP or NPNreaction can be reached. Central of alternative current loads ~ ~ ~ ~ The transistor switches an alternating voltage 10 4 V AC to a load which is also supply voltage. Note The transistor outputs of several VEGAVIB can be switches in series or parallel to connect their signals logically. The wiring must be carried out such that terminal has always higher voltage against terminal 3. The transistor switches a galvanically isolated alternating voltage 10 4 V AC to a load. 8 VEGAVIB

29 Electrical connection 3.3 Connection instruction series 500 and series 600 signal conditioning instruments If only one channel should be used on VEGATOR signal conditioning instrument, connect a resistor of 1 kω (0,5 W) to the unused connection pin of the second channel. The resistor avoids a fault signal being triggered, caused by the missing sensor. A parallel operating transistor output is available to each relay output. Module with multipoint connector acc. to DIN for carrier (rear view) d b z Reset of alarm functions You can use the fail safe relay of VEGATOR 536 as second level relay for a signaller (horn etc.). An additional key (opener) can be connected to VEGATOR 536 to deactivate the connected signaller (horn, lamp etc.) in case of a level alarm (e.g. reaching of the max. permissible level). This key can deactivate a level alarm. In case of failure (e.g. line break) the alarm is not deleted. When the key is connected, the fail safe relay has the same function as the level relay, however the fail safe relay can be reset again by pushing the key for reset of alarm functions. When an acoustic warning facility is activated when the max. level is reached, this can be switched off by pushing the key for reset of alarm functions. The second output (level relay) still signals to the processing system when max. level is reached. Note When very strong electromagnetic interferences are to be expected, we recommend the use of screened cable. The screening of the cable must only be earthed at one end of the sensor.

31 Set-up 4 Set-up 4.1 VEGAVIB Adjustment elements The diode () can be checked with closed housing. For adjustment of VEGAVIB loosen with a screwdriver first the four screws on the upper side of the instrument and remove the cover. The oscillator enables the following adjustment: A/B-switch, only with oscillators C, R and T; with oscillator Z: change-over via signal conditioning instrument Sensitivity adjustment with potentiometer (not with VEGAVIB 31) For most measured products it is not necessary to modify the pre-adjusted potentiometer (factory setting of potentiometer = 5). Use oscillator Z with suitable signal conditioning instrument (VEGATOR 534, 536, 537 and 636) to modify the integration time. The instrument version for detection of solids in water is especially adapted for use in water and must not be used for standard level measurement. The procedure for the adjustment of the instrument is identical. 1 3 With the A/B-switch (4) the switching condition of the non-contact switch (C), of the relay output (R) or the transistor output (T) can be modified. Hence the requested mode acc. to Functional schedule can be adjusted. A - max. level detection or overfill protection, B - min. level detection or protection against dry running of pumps. With oscillator Z the A/B-changeover can be made via the signal conditioning instrument. Hence not the set-up of the signal conditioning instrument. The switching sensitivity can be modified and adapted to the density of the product with potentiometer (5). This is necessary so that the level switch can reliably detect extremely liquid or heavy products. Turn the potentiometer anticlockwise to set the vibrating probe to more sensitive. According to our experience a modification of the factory setting is only necessary with very light products. When build-up can occur, it may be necessary to turn the potentiometer clockwise to improve oscillation. 1 Type plate Signal lamp (LED) 3 Terminals 4 A/B-switch 5 Potentiometer (not with VEGAVIB 31) 4 5 VEGAVIB 31
