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 thatsecures lifeandhealthof theoperatingstaffandpre-vents 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 OMD-system detecting the primary origin of the danger, the oil mist itself, to prevent the engine securely from oil mist ex-plosions.

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)

• 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 po-wer 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 humi-dity

• DesignedforVibrationsbeyondclassificationrules‑>maximum operation reliability
