LV850 LEVEL SENSOR Please follow these installation, connection and adjustment instructions carefully. Failure to comply with these instructions or misuse of this equipment will void your warranty. Equipment installation, connection and adjustment by qualified personnel only! LV850 LEVEL SENSOR NOTES: LV850 LEVEL SENSOR 1 Description Level Sensor LV850 is suitable for liquids with low relative dielectric constant.r (e.g. oil). Units come with Minimum and Maximum selector switch. It operates on the principle of electrical capacitance changes arising when an electrode surrounded by air is immersed in the medium. • LED status display • Selection of minimum and maximum function by changeover switch. Minimum switching Normally the sensor is immersed and the green LED indicates. As the level drops below the sensor the green LED extinguishes. Maximum switching Normally the sensor is not immersed and the green LED indicates. As the level rises above the sensor the green LED extinguishes. • In the event of a short-circuit in the load circuit, the green LED will extinguish and the red LED will flash. 1 LV850 LEVEL SENSOR 2 Technical Data Temperature range -20°C to +130 °C (-4°F to +266°F) short-time to +150°C (+302°F) Ambient temperature -20°C to +85°C (-4°F to +185°F) Pressure resistance max. 25 bar (367.5 PSI) Response delay approx. 0.1 s Degree of protection IP 65 Input voltage DC 9 ... 36 V Option: -metal coupling for pipe extension (see fig. 2) if the sensor is to be used as an immersion sensor mark to demonstrate compliance with applicable directive LV850 LEVEL SENSOR 3 Level Sensor Installation NOTE The Level Sensor may be installed in any attitude. 1. Ensure sufficient clearance space (see Fig. 1) in the container wall. • Ensure a type 3/4" NPT or G3/4A thread in the container wall has been provided. 2. Screw the Level Sensor into the threaded aperture using a recognized sealing material. 3. When tightening the level sensor please use the flats provided (SW32). CAUTION Do not overtighten. LV850 LEVEL SENSOR 4 Connection CAUTION Check that the supply voltage corresponds with the voltage rating shown on the system. 1. Loosen the gland (PG7)(see Fig. 1). 2. Unscrew the cover of the housing (C). 3. Feed the supply cable through the gland (PG7) and the cover (C), or through the metal coupling supplied as option (see Fig. 2). 4. Connect the cable to the terminal block (TB) (see Fig. 3). 5. Set selector switch (S) to minimum or maximum: 1. - minimum 2. - maximum 6. Connect the supply voltage. LED (red) indicates. LV850 LEVEL SENSOR 7. Increase the level until the Level Sensor is immersed in the medium. 8. Minimum Sensor: • Turn the potentiometer screw (E) to (-) until the LED (green) extinguishes. Then slowly turn to (+) until the LED indicates. Adjust the screw a further full turn to (+) to compensate for any tolerance. 9. Maximum Sensor: • Turn the potentiometer screw (E) to (+) until the LED (green) extinguishes. Then slowly turn to (-) until the LED indicates. Adjust the screw a further full turn to (-) to compensate for any tolerance. 10. Replace and tighten the cover (C) or the metal coupling (option). 11. Replace and tighten the cable gland nut (PG7). The Level Sensor is now connected, adjusted and ready for operation. 5 Operating Difficulties Problem: The Level Sensor fails to operate correctly. Solution: - The surface of the sen...
