Adjusting or checking the suction pressure
The suction pressure must be set by adjusting the pressure regulator when the engine is at standstill. Make sure ventilation of the engine room is in operation. * Connect a U-tube manometer at inspection cover (see Figure 31). (U-tube manometer is included in the service box, available as an option).* Switch on compressed air supply with inlet pressure in a range from 2 to 15 bar (before connecting the OMD the first time check the pressure).* If the negative suction pressure is already adjusted to 60 mm WC within a tolerance of 5 mm remove the U-tube manometer and finish the procedure.* Otherwise loosen counter-nut.* Turn setscrew until the negative pressure is only 60 mm WC.* Tighten counter-nut. * Remove U-tube manometerFilling of siphon blocks VN280plus of VN215/87plus system with oil
* Press the pump lever of the filling pump (see Figure 33) as many times until first oil drops come out.* Unscrew the lower siphon block plug (see Figure 32).* Insert filling pump nozzle. * Press the black nipple into the block's lower screw hole (see figure 32).* Pumps nozzle is equipped with 5 marks for max. 5-hole siphon block* Push in the nozzle to the first mark next to the nozzles tip (see Figure 34). * Fill in 12 pump strokes, then push in the nozzle ca. 10mm to the next mark and repeat filling in oil with 12 pump strokes* Repeat procedure at all marks until the nozzle reaches stop at the rear plate.At a siphon for 5 connecting tubes you will reach stop at 5th mark, at siphons for e.g. 2 connecting tubes, stop will come after 2nd mark, etc. * Close the threaded hole with the plug (a small amount of oil coming out does not impact the functionality).* Clean the outer siphon block.* Continue with the next block.Filling of siphon blocks VN180 for VN115/87plus and VN116/87plus system with oil
* Press the pump lever of the filling pump (see Figure 36) as many times until first oil drops are coming out.* Unscrew the lower siphon block plug (see Figure 35).* Insert filling pump nozzle (see Figure 37). * Screw in the fitting of the filling pump.* Press the nozzle to stop position.* Tighten the lock nut.* Fill the siphon with 8 strokes. * Remove the filling pump.* Close the threaded hole with the plug (a small amount oil coming out does not impact the functionality.* Clean the siphon block.* Continue with the next block.Filling of pipe siphons for VN115/87plus and VN116/87plus system with oil
* Remove flexible hose* Fill in 70ml lubrication oil* Fix flexible hose again Adjusting the sensitivity of the OMD
The detector determines the oil mist concentration by an optical measurement. The calculated values have the unit 'opacity'. 100% opacity means that no light is transmitted through the oil mist sample. This is equivalent to a complete white wall.The LEL (Lower Explosion Level) is equal to 47mg/l oil mist concentration in air at a temperature
