For your safety 2 For your safety 2.1 Authorised personnel All operations described in this operating instructions manual must be carried out only by trained specialist personnel authorised by the operator. For safety and warranty reasons, any internal work on the instruments must be carried out only by personnel authorised by the manufacturer. 2.2 Appropriate use OPTISWITCH 4000 C is a sensor for level detection.
Product description 3 Product description 3.1 Configuration Scope of delivery The scope of delivery encompasses: l l l Components OPTISWITCH 4000 C level sensor Test magnet Documentation - this operating instructions manual - if necessary, certificates OPTISWITCH 4000 C consists of the following components: l l Housing with electronics process fitting with tuning fork Fig. 1: OPTISWITCH 4000 C 3.
Product description fork allows use in vessels, tanks and pipes. Thanks to its simple and robust measuring system, OPTISWITCH 4000 C is virtually unaffected by the chemical and physical properties of the liquid. It functions even under difficult conditions such as turbulence, air bubbles, foam generation, buildup, strong external vibration or changing products.
Product description The packaging of standard instruments consists of environment-friendly, recyclable cardboard. For special versions, PE foam or PE foil is also used. Dispose of the packaging material via specialised recycling companies.
Mounting 4 Mounting 4.1 General instructions Switching point In general, OPTISWITCH 4000 C 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 lateral marking (notches), marking the switching point with vertical mounting. The switching point refers to water (1 g/cm³ or 0.036 lbs/in³).
Mounting 1 2 Fig. 3: Horizontal mounting 1 Switching point 2 Switching point (recommended mounting position - particularly for adhesive products) Moisture Use the recommended cables (see chapter "Connecting to power supply") and tighten the cable gland. 31762-EN-060830 You can give your OPTISWITCH 4000 C additional protection against moisture penetration by leading the connection cable downward in front of the cable entry. Rain and condensation water can thus drain off.
Mounting Pressure/Vacuum The process fitting must be sealed if there is gauge or low pressure in the vessel. Before use, check if the seal material is resistant against the measured product and the process temperature. The max. permissible pressure is stated in the "Technical data" in the "Supplement" or on the type label of the sensor. Handling The vibrating level switch is a measuring instrument and must be treated accordingly. Bending the vibrating element will destroy the instrument.
Mounting 1 Fig. 5: Marking on the welded socket 1 Marking Adhesive products In case of horizontal mounting in adhesive and viscous products, the surfaces of the tuning fork should be vertical in order to reduce buildup on the tuning fork. The position of the tuning fork is marked by a marking on the hexagon of OPTISWITCH 4000 C. With this, you can check the position of the tuning fork when screwing it in. When the hexagon touches the seal, the thread can still be turned by approx. half a turn.
Mounting Inflowing medium If OPTISWITCH 4000 C is mounted in the filling stream, unwanted switching signals may be generated. Mount OPTISWITCH 4000 C at a location in the vessel where no disturbing influence from e.g. filling openings, agitators etc. can occur. Flows To minimise flow resistance caused by the tuning fork, OPTISWITCH 4000 C should be mounted in such a way that the surfaces of the blades are parallel to the product movement.
Connecting to voltage supply 5 Connecting to voltage supply 5.1 Preparing the connection Note safety instructions Generally not the following safety instructions: l Selecting the connection cable OPTISWITCH 4000 C is connected with standard cable with round cross section. Depending on the plug connection, you have to select the outer diameter of the cable respectively so that the seal effect of the cable gland is ensured.

Set up 6 Set up 6.1 Indication of the switching status The switching status of the electronics can be checked on the upper part of the housing. 6.2 Function test OPTISWITCH 4000 C has an integrated test switch which can be activated magnetically. Proceed as follows to test the instrument: à Hold the test magnet (accessory) to the magnet symbol on the instrument housing Fig. 11: Function test The test magnet changes the current switching condition of the instrument.
Set up It is absolutely necessary that you remove the test magnet after the test from the instrument housing. 6.3 Function chart The following chart provides an overview of the switching conditions depending on the adjusted mode and level. Level Switching status Control lamp Mode max. Switch closed Green Mode max. Switch open red Mode min. Switch closed Green Mode min.
Maintenance and fault rectification 7 Maintenance and fault rectification 7.1 Maintenance When used as directed in normal operation, OPTISWITCH 4000 C is completely maintenance free. 7.2 Rectify faults Causes of malfunction OPTISWITCH 4000 C offers maximum reliability. Nevertheless faults can occur during operation. These may be caused by the following, e.g.: l l l l Sensor Process Power supply Signal processing Fault rectification The first measure to be taken is to check the output signal.
Maintenance and fault rectification 7.3 Exchange the electronics To exchange the electronics in case of failure, it is not necessary to dismount the instrument. Dismounting the electronics module can destroy the housing seal. Therefore only open the instrument if you want to insert a new electronics module. The housing seal is supplied with the electronics module. You need an electronics module type SWE50T or SWE50C. If you want to use an electronics module with a different signal output (e.g.
