JUMO Capacitive Liquid Level Switch ZELOS C01 LS 408401

JUMO ZELOS C01 LS 408401 is a compact capacitive level switch that adopts the principle of capacitive induction and is suitable for point detection of conductive/non-conductive liquids and solid particles. It has the characteristics of automatic calibration, IO Link communication, wide temperature withstand voltage, IP67 protection, etc. It is easy to install and debug and is suitable for overflow and dry operation protection in industries such as chemical, food, and pharmaceutical. The following are detailed usage instructions:

1、 Safety regulations and intended use 1 **Safety Warning * * - Used only for liquid level/material level detection and cannot be used in hazardous environments other than continuous measurement or explosion prevention. -Before installation, disconnect the power supply and ensure that the medium temperature and pressure are within the rated range (-40~+200 ℃, 10 bar). -Comply with ATEX, IEC Ex, WHG, EHEDG, 3A, UL and other certification specifications, and ensure that wiring meets electrical safety standards. 2. * * Intended use * *: overflow alarm, dry running protection, pump control, etc. of storage tanks and pipelines, suitable for liquid (including foam and adhesive media) and solid particles. 2、 Installation process 1 **Installation preparation * * - Confirm process connection (such as G1/2 thread), electrode type (PEEK material, corrosion-resistant), and electrical interface (M12 connector) matching. -Prepare torque wrench (standard torque installation, no additional seals required), shielded cable, IO Link main station (if remote configuration is required). 2. * * Mechanical Installation * * - Installed vertically/horizontally on the top or side wall of the tank, with electrodes kept away from metal structures (such as tank walls, stirrers) to avoid capacitor interference. -When installing threads, tighten with a torque wrench to ensure sealing (the sensor comes with a built-in seal, no additional seals are required). 3. * * Electrical wiring * * - Power supply: DC 10-36 V, pay attention to positive and negative poles, and backup reverse polarity protection. -Output: PNP/NPN/push-pull (switch capacity DC 36 V/200 mA), can directly drive PLC input or small relays. -IO Link: Connected through M12 connector, supports remote configuration and fault diagnosis. -Wiring: Separate the power line from the signal line, and ground the shielded wire at one end to reduce electromagnetic interference. 3、 Debugging and Calibration 1 **Automatic Calibration (Recommended) * * - When the tank is empty, press the sensor button or start automatic calibration through the IO Link master station, and the sensor will automatically learn the capacitance value of the empty tank. -After calibration, the sensor can distinguish between the medium and cleaning solution/foam, and the electrode adhesion will not affect the detection. 2. * * Manual Configuration (IO Link) * * - Connect the IO Link master station to the JUMO software, set parameters such as switch point, hysteresis, output type (PNP/NPN/push-pull), fault alarm, etc. -Support firmware online updates to reduce downtime. 3. * * Status indication * *: The 360 ° LED indicator light displays the working/fault status (such as short circuit, cable breakage), in compliance with NAMUR and VDI/VDE standards. 4、 Operation and Maintenance 1 **Daily operation * * - Monitoring LED status: green normal, red fault, flashing indicates calibration or communication abnormality. -Real time reading of switch status, capacitance value, and fault codes through IO Link, and remote adjustment of parameters. 2. * * Maintenance points * * - Regularly clean electrodes (high viscosity media), check cables and seals, and ensure IP67 protection level. -Avoid severe vibrations and impacts to prevent electrode damage. -Troubleshooting: When short circuit/reverse polarity protection is triggered, check the wiring; When the cable breaks, detect the line fault through IO Link. 5、 Fault diagnosis and handling | Fault symptoms | Possible causes | Handling methods | | ---- | ---- | | | LED red constant light | Short circuit, reverse polarity, parameter error | Check wiring, recalibrate, restore default parameters | | Switch misoperation | Electrode contamination, capacitance interference | Clean electrodes, adjust installation position, away from metal structures | | IO Link communication failure | Cable damage, main station configuration error | Replace cables, check communication parameters, reconnect | | No signal output | Power failure, output type mismatch | Check power supply, reset output type | VI. Selection and replacement reference 1 If longer electrodes are required, the same series of long electrode models can be selected; If higher pressure is required (such as 600 bar), the MAERA series static pressure level switch can be replaced. When replacing traditional float switches, there is no need to consider medium density, making installation more flexible and maintenance costs lower.
