Product description 3 Product description 3. Configuration Scope of deivery Components The scope of deivery encompasses: KSR-TF 6 eve sensor Documentation - this operating instructions manua - Additiona instructions manua "Safety Manua - Functiona safety according to IEC 6508 (SIL)" - Ex-specific "Safety instructions" (with Ex-versions) - if necessary, further certificates KSR-TF 6 consists of the foowing components: Housing cover Housing with eectronics process fitting with tuning fork 2 3 Fig. : KSR-TF 6 Housing cover 2 Housing with eectronics 3 Process fitting 3.2 Principe of operation Area of appication KSR-TF 6 is a eve sensor with tuning fork for eve detection. It is designed for industria use in a areas of process technoogy and can be used in iquids. Typica appications are overfi and dry run protection. With a tuning fork of ony 40 mm ength, KSR-TF 6 can be aso mounted, e.g. in pipeines from DN 25. The sma tuning fork KSR-TF 6 - with contactess eectronic switch 7
Product description aows use in vesses, tanks and pipes. Thanks to its simpe and robust measuring system, KSR-TF 6 is virtuay unaffected by the chemica and physica properties of the iquid. It functions even under difficut conditions such as turbuence, air bubbes, foam generation, buidup, strong externa vibration or changing products. Faut monitoring The eectronics modue of KSR-TF 6 continuousy monitors via frequency evauation the foowing criteria: Strong corrosion or damage on the tuning fork oss of vibration Line break to the piezo drive If a mafunction is detected or in case of power faiure, the eectronics takes on a defined switching condition, i.e. the contactess eectronic switch opens (safe condition). Functiona principe Suppy The tuning fork is piezoeectricay energised and vibrates at its mechanica resonance frequency of approx. 200 Hz. The piezos are fixed mechanicay and are hence not subject to temperature shock imitations. The frequency changes when the tuning fork is covered by the medium. This change is detected by the integrated osciator and converted into a switching command. KSR-TF 6 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.). The data for power suppy are stated in chapter "Technica data" in the "Suppement". 3.3 Operation With the factory setting, products with a density >0.07 g/cm³ (>0.025 bs/in³) can be measured. The instrument can be adapted if products with ower density shoud be measured. On the eectronics modue you wi find the foowing indicating and adjustment eements: signa amp for indication of the switching condition (green/ red) DIL switch for sensitivity adjustment 8 KSR-TF 6 - with contactess eectronic switch
Product description Mode switch for seection of the switching condition (A/B) 3.4 Storage and transport Packaging 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 2480. The packaging of standard instruments consists of environment-friendy, recycabe cardboard. In addition, the sensor is provided with a protective cover of ABS. For specia versions PE foam or PE foi is aso used. Dispose of the packaging materia via speciaised recycing companies.

Mounting 4 Mounting 4. Genera instructions Switching point In genera, KSR-TF 6 can be mounted in any position. The instrument must be mounted in such a way that the tuning fork is at the height of the requested switching point. The tuning fork has atera markings (notches) that indicate the switching point with vertica mounting. The switching point refers to water with the basic setting of the sensitivity switch 0.7 g/cm³ (0.025 bs/in³). When mounting KSR-TF 6, make sure that this marking is at the height of the requested switching point. Keep in mind that the switching point of the instrument is shifted if the medium has a density other than water - water g/cm³ (0.036 bs/in³). For products <0.7 g/cm³ (0.025 bs/in³) and >0.5 g/cm³ (0.08 bs/in³) the density switch must be set to 0.5 g/cm³. Keep in mind that foams with a density >0.45 g/cm³ (0.06 bs/ in³) are detected by the sensor. This can cause fauty switchings particuary when used as dry run protection system. 2 3 4 Fig. 2: Vertica mounting Switching point approx. 3 mm (0.5 in) 2 Switching point with ower density 3 Switching point with higher density 4 Switching point approx. 27 mm (.06 in) 0 KSR-TF 6 - with contactess eectronic switch

Fig. 5: Fork position with fange versions Moisture Use the recommended cabes (see chapter "Connecting to power suppy") and tighten the cabe gand. You can give your KSR-TF 6 additiona protection against moisture penetration by eading the connection cabe downward in front of the cabe entry. Rain and condensation water KSR-TF 6 - with contactess eectronic switch
Mounting can thus drain off. This appies mainy to mounting outdoors, in areas where moisture is expected (e.g. by ceaning processes) or on cooed or heated vesses. Fig. 6: Measures against moisture penetration Transport Pressure/Vacuum Handing Do not hod KSR-TF 6 on the tuning fork. Particuary with fange or tube versions, the tuning fork can be damaged just by the weight of the instrument. Transport coated instruments very carefuy and avoid touching the tuning fork. Remove the protective cover just before mounting. 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. The vibrating eve switch is a measuring instrument and must be treated accordingy. Bending the vibrating eement wi destroy the instrument. Warning: The housing must not be used to screw the instrument in! Appying tightening force on the housing can damage its rotationa mechanica parts. To screw in, use the hexagon above the thread. 2 KSR-TF 6 - with contactess eectronic switch
Mounting 4.2 Mounting instructions Weded socket KSR-TF 6 has a defined thread starting point. This means that every KSR-TF 6 is in the same fork position after being screwed in. Remove therefore the suppied sea from the thread of KSR-TF 6. This sea is not required when using a weded socket with O-ring in front. Keep in mind that this weded socket is not suitabe for coated instrument versions. Screw KSR-TF 6 competey into the weded socket. The ater position can be determined aready before weding. Mark the appropriate position of the weded socket. Before weding, unscrew KSR-TF 6 and remove the rubber ring from the weded socket. The weded socket has a marking (notch). Wed the socket with the notch facing upward, or in case of pipeines, aigned with the direction of fow. Fig. 7: Marking on the weded socket Marking Adhesive products In case of horizonta mounting in adhesive and viscous products, the surfaces of the tuning fork shoud be vertica in order to reduce buidup on the tuning fork. On the screwed version you wi find a marking on the hexagon. With this, you can check the position of the tuning fork when screwing it in. When the hexagon touches the sea, the thread can sti be turned by approx. haf a turn. This is sufficient to reach the recommended instaation position. With fange versions, the fork is directed to the fange hoes. When used in adhesive and viscous products, the tuning fork shoud protrude into the vesse to avoid buidup. For that reason, sockets for fanges and mounting bosses shoud be avoided when mounting horizontay. KSR-TF 6 - with contactess eectronic switch 3
Mounting Infowing medium Fows If KSR-TF 6 is mounted in the fiing stream, unwanted mismeasurements may resut. Mount KSR-TF 6 at a ocation in the vesse where no disturbing infuence from e.g. fiing openings, agitators, etc. can occur. To minimise fow resistance caused by the tuning fork, KSR-TF 6 shoud be mounted in such a way that the surfaces of the bades are parae to the product movement. 4 KSR-TF 6 - with contactess eectronic switch

Connect the power suppy according to the foowing diagrams. Osciator SWE60C is designed in protection cass. 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 KSR-TF 6 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. In Ex appications, the instaation reguations for hazardous areas must be given priority. The data for power suppy are stated in chapter "Technica data" in the "Suppement". KSR-TF 6 is connected with standard cabe with round cross section. An outer cabe diameter of 5 9 mm (0.2 0.35 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. In hazardous areas, ony use approved cabe connections for KSR-TF 6.
