  • Page 4: For Your Safety

    During work on and with the device, the required personal protective equipment must always be worn. Appropriate use The OPTISWITCH 4000 C 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.

    This information is only valid for USA and Canada. Hence the follow- ing text is only available in the English language. Installations in the US shall comply with the relevant requirements of the National Electrical Code (ANSI/NFPA 70). Installations in Canada shall comply with the relevant requirements of the Canadian Electrical Code. OPTISWITCH 4000 C • Transistor (PNP)

  • Page 6: Product Description

    Article numbers, documentation Principle of operation Application area OPTISWITCH 4000 C is a point level sensor with tuning fork for point level detection. It is designed for industrial use in all areas of process technology and can be used in liquids.

  • Page 7: Adjustment

    Voltage supply OPTISWITCH 4000 C is a compact instrument, i.e. it can be oper- ated 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. a warning system, a pump etc.).

  • Page 9: Mounting

    DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. Switching point In general, OPTISWITCH 4000 C can be installed in any position. The instrument only has to be mounted in such a way that the tuning fork is at the height of the desired switching point.
  • Page 10 Use the recommended cables (see chapter "Connecting to power supply") and tighten the cable gland. You can give your OPTISWITCH 4000 C 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 applies mainly to outdoor mounting as well as installation in...

  • Page 11: Mounting Instructions

    Welded socket For threaded versions of OPTISWITCH 4000 C in combination with a mounting boss with O-ring in front and welding marking. OPTISWITCH 4000 C with thread sizes ¾" and 1" have a defined thread. This means that every OPTISWITCH 4000 C is in the same position after being screwed in. Remove therefore the supplied flat seal from the thread of OPTISWITCH 4000 C. This flat seal is not required when using a welded socket with front-flush seal. Before welding, unscrew OPTISWITCH 4000 C and remove the rub- ber ring from the welded socket.
  • Page 12 Fig. 6: Adhesive products Inflowing medium If OPTISWITCH 4000 C is mounted in the filling stream, unwanted false measurement signals can be generated. For this reason, mount OPTISWITCH 4000 C at a position in the vessel where no disturbanc- es, e.g. from filling openings, agitators, etc., can occur. Product flow To make sure the tuning fork of OPTISWITCH 4000 C generates as little resistance as possible to product flow, mount the sensor so that the surfaces are parallel to the product movement.

  • Page 13: Connecting To Power Supply

    Make sure that the cable used has the required temperature resist- ance and fire safety for max. occurring ambient temperature When mounting outdoors, on cooled vessels or in moist areas in which cleaning is made with steam or high pressure, the sealing of the cable gland is very important.
