Installation, maintenance, and commissioning of the level limit switch must be conducted by qualified personnel. The product should be used as per the manual, with attention to warnings about potential risks of electric shock, serious injury, or material damage. For technical support, contact UWT GmbH or your local supplier.
The level limit switch is designed for monitoring levels in containers and silos, suitable for powdery and granulated bulk materials. It is applicable in industries such as building materials, food, plastics, timber, chemical, and mechanical engineering. The device can be mounted on the lateral container wall or from the top using an extension piece, with probe lengths extending up to 20 meters.
The switches are available in various housing versions, including standard and explosion-proof models. They feature adjustable sensitivity, vibration frequency, and signal delay. Electrical data includes connection terminals, cable entry specifications, and power supply requirements. Mechanical data covers housing materials, process connections, and operating conditions, such as ambient and process temperatures.
The devices come with a range of Ex-approvals for use in hazardous areas. Options include enhanced sensitivity and separate housing configurations.
Instructions for mounting the device and performing electrical installations are provided to ensure proper setup and operation.
The device features signal output options, including floating relay and open collector configurations, with built-in LED indicators for status monitoring.
Sensitivity settings can be adjusted in two levels, and regular maintenance is recommended to ensure optimal performance.
Special considerations are provided for using the device in hazardous locations, ensuring compliance with safety standards.
Detailed assembly instructions for different models are included, along with guidelines for proper disposal of the device.
The document outlines the mechanical and operational specifications for the Vibranivo® level limit switch series VN 1000 / 2000 / 5000 / 6000. Key mechanical specifications include a lateral mechanical load of 600 N on oscillator rods, a maximum mechanical torque of 300 Nm for VN ..030 and 100 Nm for VN ..040, and a maximum tractive force of 2 kN for VN ..050. The maximum process pressure varies by model, with VN ..020, VN ..030, and VN ..040 supporting up to 16 bar, while VN ..050 supports up to 6 bar.
The devices are suitable for outdoor use, withstanding relative humidity from 0 to 100% and altitudes up to 3,000 m for VN 1000/2000 and 2,000 m for VN 5000/6000. Transport and storage conditions are specified with temperature ranges from -40 to +80°C and humidity from 20 to 85%.
The devices comply with various international standards and approvals, including CE/UKCA, FM/CSA, TR-CU, and EN 61010-1 for ordinary locations, and ATEX, UKEX, IEC-Ex, FM, CSA, TR-CU, INMETRO, KC, and CCC for hazardous locations. Compliance with EMC standards (EN 61326 -A1) and RoHS directive 2011/65/EU is also mentioned.
Installation guidelines emphasize the importance of proper mounting to avoid mechanical damage and ensure safety, especially in hazardous locations. Detailed instructions on mounting, sealing, and electrical connections are provided, including the use of PTFE sealing tape and grounding to prevent static charging.
Optional accessories include weather protection covers, sliding sleeves, mounting sets, signal lamps, and various plug types. Material compatibility and installation constraints for these accessories are specified, particularly in hazardous environments.
The document advises on the detection of solids in water, specifying that only certain models (VN 1020/1030/5020/5030) are suitable for this application. It also discusses the impact of environmental factors on product lifetime and provides guidelines for handling and maintenance to ensure device longevity and reliability.
The Vibranivo® series VN 1000/2000/5000/6000 level limit switches provide signal output through electronic modules with settings of 8/16 mA or 4-20 mA. The output indicates the vibration signal quality, allowing for material build-up detection and vibration behavior evaluation using a PLC or data logger.
Sensors are factory preset, but sensitivity can be adjusted for materials prone to caking. The VN 1000/5000 and VN 2000/6000 models have different minimum bulk density settings, with options for enhanced sensitivity using a potentiometer.
Instructions are provided for safely replacing electronic modules, emphasizing the importance of using intrinsically safe marked modules where required. Maintenance includes frequent checks for mechanical damage, proper sealing, and cleaning with compatible agents.
The document outlines the permissible zones for use in hazardous locations, detailing equipment protection levels for dust and gas applications. Specific conditions for electrostatic charge prevention and flameproof joint maintenance are highlighted.
Temperature ratings and maximum surface temperatures are provided for both intrinsic and non-intrinsic safe modules. The document clarifies that ATEX approvals cover atmospheric pressure only, with deviations requiring expert assessment.
Detailed instructions for assembling the VN ..040 model with standard housing are included, emphasizing the importance of matching thread types and ensuring mechanical stability.
This document provides technical specifications and assembly instructions for the Vibranivo® level limit switch series VN 1000 / 2000 / 5000 / 6000. It includes detailed procedures for assembly, cable preparation, and sealing requirements.
- Tightening torque for assembly is 50 Nm.
- Use a 36 mm (1.42") open-end wrench for attaching components.
- Sealing requirements include IP67 or NEMA 4 standards, with specific instructions for G and NPT versions.
- Ensure correct threading type (G or NPT) for extension tubes and oscillating pieces.
- For G version, use original O-rings from the manufacturer to ensure proper sealing.
- For NPT version, use temperature-resistant sealing for up to 150°C (302°F) with a maximum thickness of 0.2 mm (0.008").
- Shorten sensor cables to specified lengths (150 mm or 80 mm) and prepare as shown in diagrams.
- Connect sensor cables to terminal connection pieces and ensure all terminals are tightly screwed in.
- Use shrink hoses to cover exposed wires and ensure proper insulation.
- When removing and reassembling connection cables, follow the factory-provided cable situation as a sample.
- Ensure the cable gland is tightly closed to maintain ingress protection standards.
- The product is made of recyclable materials, and recycling should be done by a specialized company.
