Please read these operating instructions before unpacking and putting the unit into operation. Follow the instructions precisely as described herein. The instruction manuals on our website www.kobold.com are always for currently manufactured version of our products. Due to technical changes, the instruction manuals available online may not always correspond to the product version you have purchased.
5. Operating Principle The optical level sensors of model OPT have been developed for monitoring transparent liquids. Due to the very small dimensions, very slight switching hysteresis and high repeatability, the instruments are also suited for service in small vessels. The optical sensor is situated in a robust housing. It comprises a plastic hollow hemisphere, in which the infrared diode is fitted as a transmitter and a semiconductor as a receiver.
6. Mechanical Connection Before installation: Make sure that the maximum operating pressures and temperatures allowed for this device are not exceeded (see 8. Technical Information). Avoid mounting the Optical Level Sensor vertically downward from the top of the container cover. In this position, drops accumulating on the optical sensor can cause the sensor to report an apparent, false, simulated level (switching point reached).
7. Electrical Connection 7.1 General Information Attention! Make sure that the voltage values of your system correspond with the voltage values of the measuring unit. Make sure that the supply wires are de-energised. 7.2 Terminal Connection Diagrams Page 6 OPT-Y K05/1022...
