    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 67 • Two-wire...

    Chemical properties of the medium • Abrasion and mechanical influences Switching point In general, VEGACAP 67 must be mounted vertically. The instrument must be mounted in such a way that the probe is at the height of the requested switching point. Welding work Before beginning the welding work, remove the electronics module from the sensor.

  • Page 14: Mounting Instructions

    4 Mounting 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 67, but check if you can mount a short level switch on the side of the vessel in horizontal position. Inflowing medium If the instrument is mounted in the filling stream, unwanted false measurement signals can be generated. For this reason, mount the instrument at a position in the vessel where no disturbances, e.g.

  • Page 16 Make sure that the max. permissible tensile load of the suspension cable is not exceeded. The danger of this happening exists particu- larly with very heavy solids and large meas. lengths. The max. permis- sible load is stated in chapter " Technical data". VEGACAP 67 • Two-wire...

  • Page 17: Connecting To Power Supply

    Connect the operating voltage according to the following diagrams. Take note of the general installation regulations. As a rule, connect VEGACAP 67 to vessel ground (PA), or in case of plastic vessels, to the next ground potential. On the side of the instrument housing there is a ground terminal between the cable entries.

    After connecting to voltage supply or after a voltage recurrence, the instrument passes a certain switch on routine. By lowering the current value when switching on, the instrument can output briefly a fault message. I/mA 20,5 < 2,3 Fig. 13: Warm-up reaction Measured value VEGACAP 67 • Two-wire...

  • Page 21: Setup

    Note: As a rule, always set the mode with the mode switch of the signal conditioning instrument before starting setup VEGACAP 67. The switching output will change if you set the mode switch afterwards. This could possibly trigger other connected instruments or devices.
  • Page 22 Measuring range selec- tion switch (1) selection switch (1) on VEGACAP 67 you can change the sensitivity of the probe to the electrical properties of the product and the condi- tions in the vessel. This is necessary so that the level switch can also reliably detect products e.g. with very low or very high dielectric figure.
