Product catalog summary

Safety Notes and Technical Support
Installation, maintenance, and commissioning of the VN 4000 level limit switch should be conducted by qualified personnel only. The product must be used according to the manual, with attention to warnings about electric shock and material damage risks. For technical support, contact UWT GmbH or your local supplier.

Introduction
The VN 4000 is designed for level monitoring in containers and silos, suitable for powdery and granulated materials with a density greater than 30 g/l. It is applicable in industries such as building materials, food, plastics, timber, chemical, and mechanical engineering. The device can be mounted laterally or from the top of the container, with a probe length up to 4 meters.

Technical Data
The VN 4000 features various connection options, including thread, flange, and triclamp. It operates with a universal voltage supply and offers a floating relay DPDT signal output. The housing is made of aluminum with a degree of protection IP67. Operating conditions include ambient temperatures from -40°C to +60°C and process temperatures up to +150°C.

Approvals
The device is approved for general and hazardous locations, with certifications such as CE, ATEX, IEC-Ex, and others. It complies with EMC standards and is made from food-grade materials.

Options
Optional features include weather protection covers, sliding sleeves, and signal lamps. Various plug options are available, though some are not suitable for hazardous locations.

Mounting and Installation
Proper installation is crucial to maintain process pressure and ensure chemical resistance. The device should be mounted considering the flow of materials and silo wall proximity. Mechanical load limits and temperature ranges must be observed.

Electrical Installation
Electrical connections should be made using the specified terminals and cable entries. The device supports both AC and DC power supplies.

Signal Output and Sensitivity Setting
The VN 4000 provides a signal output via a built-in LED, indicating the status of the signal. Sensitivity settings can be adjusted based on material density.

Maintenance
Regular maintenance is required to ensure optimal performance, especially in environments with high material flow rates.
