    During work on and with the device, the required personal protective equipment must always be worn. Appropriate use The VEGACAP 62 is a sensor for point level detection. You can find detailed information about the area of application in chapter " Product description". Operational reliability is ensured only if the instrument is properly used according to the specifications in the operating instructions manual as well as possible supplementary instructions.

    That is why we have introduced an environment management system with the goal of continuously improving company environmental pro- tection. The environment management system is certified according to DIN EN ISO 14001. Please help us fulfil this obligation by observing the environmental instructions in this manual: • Chapter " Packaging, transport and storage" • Chapter " Disposal" VEGACAP 62 • Relay (DPDT)

  • Page 9: Principle Of Operation

    3 Product description Principle of operation Application area VEGACAP 62 is a point level sensor for use in all areas of industry. The partly insulated probe is suitable for the measurement of bulk solids and liquids. The proven mechanical construction offers high functional safety. Functional principle Probe, measured product and vessel wall form an electrical capacitor.

    Protective cover The protective cover protects the sensor housing against soiling and intense heat from solar radiation. Flanges Screwed flanges are available in different versions according to the following standards: DIN 2501, EN 1092-1, BS 10, ASME B 16.5, JIS B 2210-1984, GOST 12821-80. VEGACAP 62 • Relay (DPDT)

  • Page 11: Mounting

    Use the recommended cables (see chapter " Connecting to power supply") and tighten the cable gland. You can give your instrument additional protection against moisture penetration by leading the connection cable downward in front of the cable gland. Rain and condensation water can thus drain off. This VEGACAP 62 • Relay (DPDT)
  • Page 12 Condensation If condensate forms on the vessel top, the run-off liquid can cause bridging and hence faulty switchings. For this reason, use a screening tube or a longer insulation. The length depends on the amount of condensate and the drain-off be- haviour of the product. VEGACAP 62 • Relay (DPDT)

  • Page 13: Mounting Instructions

    Agitators and fluidization Due to the effects of agitators, equipment vibration or similar, the level switch can be subjected to strong lateral forces. For this reason, do not use an overly long electrode for VEGACAP 62, but check if you can mount a short level switch on the side of the vessel in horizontal position. Extreme vibration caused by the system, e.g. due to agitators or turbulence in the vessel from fluidisation, can cause the probe of VEGACAP 62 to vibrate in resonance.
  • Page 14 To achieve a very precise switching point, you can install VEGACAP 62 horizontally. However, if the switching point can have a tolerance of a few centimeters, we recommend mounting VEGACAP 62 approx. 20° inclined to the vessel bottom to avoid buildup. Install rod probes in such a way that the probe projects freely into the vessel. When the instrument is mounted in a tube or nozzle, buildup...
  • Page 15 The probe must be mounted in a way that takes the arrangement of the filling and emptying apertures into account. To compensate measurement errors caused by the material cone in cylindrical vessels, the sensor must be mounted at a distance of d/6 from the vessel wall.

  • Page 20 Inductive loads also result from the connection to a PLC input or output and/or in combination with long cables. It is imperative that you take measures to extinguish sparks to protect the relay contact (e.g. Z diode) or use an electronic version with transistor output. VEGACAP 62 • Relay (DPDT)

  • Page 21: Setup

    Note: As a rule, always set the mode with the mode switch (3) before start- ing setup VEGACAP 62. The switching output will change if you set the mode switch (3) afterwards. This could possibly trigger other con- nected instruments or devices.
  • Page 22 In some cases the lowest range (range 1 = highest sensitivity) is not sufficient to adjust the full switch point. This would make another filling procedure necessary. For this reason we recommend setting and noting the empty switching point in all three meas. ranges. Set the meas. range se- VEGACAP 62 • Relay (DPDT)
