2 VISATRON VN 301 plus /VN 301 plus EX technical data OIL MIST DETECTION MULTI-SENSOR-SYSTEM Functional overview The Oil Mist Detector (OMD) VISATRON VN301plus /VN- 301plusEX System from SCHALLER AUTOMATION protect large diesel engines against oil mist explosion, caused by spontaneously occurring oil mist. It is part of a safety system that secures life and health of the operating staff and prevents heavy damages to the engine. It is not possible to directly monitor all potential sources of oil mist inside a large Diesel, Gas or Dual Fuel engine. There are main bearings, large end bearings, pistons, liners, sliders, pumps, camshaft bearings, chains, gears or even tools left behind from installation all of these parts could produce oil mist e.g. in case of lubrication problems. Therefore the philosophy is to use the SCHALLER AUTOMATION OMDsystem detecting the primary origin of the danger, the oil mist itself, to prevent the engine securely from oil mist explosions. The VISATRON VN301plus /VN301plusEX System consists of the following parts: 1 to 20 VISATRON VN301plus Sensor Units 1 to 2 VISATRON VN301plus Central Units including compressed air distribution system and protection cover Ready made hybrid cables (electric and air supply) Monitoring device Remote Indicator II (optional) VN301 plus /VN301 plus EX Sensor Unit Dimensions See drawings Weight Sensor Unit: 850g Suction manifold: 350g Max. cable length Sensor Unit 30 m Engine mount Sensor Unit G3/4 M27x1.5 M33x2 IP Protection Class IP 65 VN301plus EX ATEX Certified according II /2G Ex op is IIB T4 /Gb 2

False Alarm free operation Extremely low maintenance requirements Designed for engine lifetime Based on below innovations Only system on the market using pressurized air for every single sensor Use of Hybrid cables, leading air supply, signal and power supply via one cable, -> can be handled like ordinary copper cables, tubeless Pressurized air for active clean keeping of the optics -> no false Alarms, extremely low maintenance required Pressurized air for active extraction of atmosphere from engine -> fast reaction if engine needs to be stopped Floating opacity zero adaptation to naturally opacity of a normal running engine, even worn-> no false Alarms but fast reaction if engine needs to be stopped Every sensor heated -> no false Alarms due to humidity Designed for Vibrations beyond classification rules -> maximum operation reliability 4
