  • Page 4: For Your Safety

    During work on and with the device, the required personal protective equipment must always be worn. Appropriate use The VEGACAP 35 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 35 • Relay (DPDT)

  • Page 6: Product Description

    – If necessary, further certificates Information: Optional instrument features are also described in this operating instructions manual. The respective scope of delivery results from the order specification. Constituent parts The VEGACAP 35 consists of the components: • Process fitting with probe • Housing with electronics • Housing lid Fig.

  • Page 7: Principle Of Operation

    The capacitance change is converted by the electronics module into a switching command. Voltage supply VEGACAP 35 is a compact instrument, i.e. it can be operated without external evaluation system. The integrated electronics evaluates the level signal and outputs a switching signal. With this switching signal, a connected device can be operated directly (e.g.

    Technical data - Ambient conditions" • Relative moisture 20 … 85 % Lifting and carrying With instrument weights of more than 18 kg (39.68 lbs) suitable and approved equipment must be used for lifting and carrying. VEGACAP 35 • Relay (DPDT)

  • Page 9: Mounting

    DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used indoors as well as outdoors. Switching point In general, VEGACAP 35 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.

  • Page 10: Mounting Instructions

    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 35, 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.
  • Page 11 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. VEGACAP 35 • Relay (DPDT)

  • Page 13 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 35 • Relay (DPDT)

  • Page 14: Connecting To Power Supply

    Wiring plan - single chamber housing Wiring plan We recommend connecting VEGACAP 35 in such a way that the switching circuit is open when there is a level signal, line break or failure (safe state).
  • Page 15 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 35 • Relay (DPDT)

  • Page 16: Setup

    Note: As a rule, always set the mode with the mode switch (5) before start- ing setup VEGACAP 35. The switching output will change if you set the mode switch (5) afterwards. This could possibly trigger other con- nected instruments or devices.
  • Page 17 The measuring system is immediately ready for operation. ment The switching point must no longer be set with VEGACAP 35. The probe has an active length and a screen segment. Thanks to the screen segment, the so called standing capacitance, caused by the vessel after installation of the probe, is mainly compensated.

    Should these measures not be successful, please call in urgent cases 24 hour service hotline the VEGA service hotline under the phone no. +49 1805 858550. The hotline is also available outside normal working hours, seven days a week around the clock.
  • Page 21 Remove the electronics module. Check the resistance between the the probe two plug connections. There must no longer be a connection (high impedance). If there is still a connection, exchange the instrument or return it for repair VEGACAP 35 • Relay (DPDT)
  • Page 22 In both cases, the probe must be repaired in our premises. Contact 4 against vessel The electrical connection between contact 4 and metal vessel (not the mounting boss or probe flange) should good. Measure the resist- ance value between contact 4 and vessel with an ohmmeter (range very small). • Shortcircuit (0 … 3 Ω) - optimum connection • Resistor > 3 Ω - bad connection VEGACAP 35 • Relay (DPDT)
