1Introduction and functional overview
The newly developed VISATRON® VN87plus EX Oil Mist Detector (OMD) from
SCHALLER AUTOMATION protects large diesel engines against oil mist explosion,
caused by spontaneously occurring oil mist. It is part of a safety system that
secures the life and health of the operating staff and prevents heavy damages to
the engine.
SCHALLER AUTOMATION developed this device to meet the IACS UR M10.
The VN115/87plus EX is compliant to ATEX 2014/34/EU.
It is not possible to directly monitor all potential sources of oil mist inside a large
diesel 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 of SCHALLER AUTOMATION is that only OMD-systems can
securely prevent oil mist explosions by detecting the primary origin of danger: the
oil mist itself.
The VISATRON® VN115/87plus EX OMD-System uses the approved wear-free
suction system to continuously extract the atmosphere of the crankcase
compartments and other engine locations. The system works actively and is not
simply waiting for oil mist clouds. This ensures proper reaction times from the
beginning of oil mist generation to an oil mist alarm.
To avoid false alarms, caused by splash oil, the suction system makes use of
Schaller's special suction funnels working independent of the rotation sense of the
engine. Additional draining components ensure correct working under all operating
conditions. This includes the application in power plants as well as on vessels with
their static or dynamic inclinations. False alarms initiated by condensing water
vapour are prevented by an integrated heater inside the measuring head housing.
The OMD-System consists of following parts:
VISATRON® VN115/87plus EX oil mist detector
Protection cover
Suction system including pressure regulator
Monitoring device (optional)
Filter for air support / water and oil separator
The VN115/87plus EX (see Figure 1) is approved to work and use in potentially
explosive atmospheres.
All devices have a measuring head (2) which includes the optical measuring track
under the control cover (3) and a display to give the user all important information
for normal operations conditions. The measuring head is mounted on a vibration
protected base plate.

The negative pressure for the suction system is generated by an air jet pump (1)
working with the Venturi principle. The electrical interface is integrated within a
socket housing (5). The mating plug contains the Oil-Mist-Alarm button. The device
can be connected directly to the engine safety system. The interface includes two
Oil-Mist-Alarm outputs, a Pre-Alarm output and a Ready signal.
VN115/87plus EX
Figure 1: VISATRON® VN115/87plus EX
VN115/87plus EX
The suction system is connected to the common "Connecting Box" (4). This type of
oil mist detector is able to detect an oil mist development, without identifying the
location of the oil mist source inside the engine.
In normal operation mode the VN115/87plus EX samples the atmosphere of the
engine at all suction points in parallel through the suction system to the measuring
head.
The VN115/87plus EX offers two alarm levels.
The Main-Alarm level can be adjusted with a switch at the rear side of the
measuring head.
The Pre-Alarm will be activated at fix 70% of the Main-Alarm level.
To keep the optical track clean, the VN115/87plus EX use clean scavenging air in
front of the filter glasses. This air is derived from the compressed air driving the air
jet pump.
The device is integrated in a mounting unit. The scope of supply includes an air
cleaner, an additional pressure regulator unit and a protection cover.

Figure 2: VISATRON® VN115/87plus EX oil mist detector with protection cover
and pressure regulator unit
The suction system always requires a so called 'suction funnel' (see page 20, Figure
13) at each suction point. This prevents the system against incoming splash oil.
During normal operation mode of an engine the OMD sucks out a small
concentration of oil mist which was generated by blow-by or mechanical spraying.
This oil mist may fall out in the suction pipes and must be drained out the pipes.
Ideally, drainage flow back ends inside the engine’s crankcase.
Figure 3:
Optional Siphon block VN180 optional Pipe siphon
The best method on a VN115/87plus EX installation to drain the system is to use
pipe siphons. Also recommended is the use of siphon blocks.
On 2-stroke engines the crankcase and the combustion chambers are separated by
stuffing boxes, which let the crankcase be nearly free of blow-by. Therefore it's also
possible to use the suction funnel as draining device. In this case it is necessary to
mount the suction pipes with an inclination of greater than 6°.
It is not allowed to blow the air into the engine room!

Caution! The exhaust from the air jet pump must be blown
back into the crankcase. It’s not allowed to blow the air into
the engine room! It could be dangerous for personnel safety,
because of the air-fuel-mixture.
Remote monitoring devices:
The OMD device can be connected to Schaller's monitoring devices Remote
Indicator II to monitor the oil mist concentration and the status of the OMD device
from a safe location as requested by IACS UR M10. The connection to the
monitoring devices is realized by a RS485 two-wire bus.
Figure 4: Optional Remote Indicator II
Additionally Schaller realized an integration of the VISATRON® VN115/87plus EX
into ship automation systems (e.g. Mega-Guard of Praxis Automation).
Thus, the VN115/87plus EX is a further contribution to safety at sea. Our goal is to
avert damage to assets, personnel and the environment.

2Installation instructions
2.1 Mechanical installation
2.1.1 Basics
There are multiple potential sources of oil mist inside an engine. These are for
example defective main bearings, connecting rod bearings as well as piston
seizures, chains and covers of pumps. For each of these individual sources you
could determine the "optimum" suction point. The result would be a vast number of
holes to be distributed over the entire engine. To find out a safe and economic
solution to monitor oil mist SCHALLER AUTOMATION recommends the OMDEA-test
(Oil Mist Detection Efficiency Approval). In each case the following rules are
recommended.
CAUTION! Do not ignore the warnings. The safety of persons
can be endangered
Following rules are recommended by SCHALLER AUTOMATION:
Use at least one suction point per compartment.
Use always the long version of the suction funnels. This makes the
installation independent from the rotation sense of the engine.
At least one suction point per chain drive or gear drive is necessary.
Avoid the splash oil disk of the crankshaft bearings.
Select points in the upper area of the crankcase, as oil mist tends to rise
upwards!
The detection unit has to be placed above the suction points.
Installation Rules: it is not allowed to make U-bends or kinks in the tubing
system.
oVN115 with pipe siphons: Mount one pipe siphon at each end of the
horizontal header pipes, place the pipes a little bit above the suction
points and connect the pipes and the engine wall connections with
flexible tubes.
oVN115 with siphon blocks: Use one siphon block at each compartment.
If possible mount the device on the engine side opposite to the crankcase
relief valves, to reduce danger to the crew during a damage situation.
If possible place the VISATRON® detection unit in the center of the engine to
avoid long pipe runs.
Select only suction points which allow the use of long suction funnels. In this
case the installation side is independent from the rotation sense of the
engine. Installations without any suction funnels are not allowed.

Industrielle Automationstechnik GmbH & Co. KG Tel. [phone]/ Fax -260 / eMail: [e-mail] / www.schaller.de
If recommended by engine builder, determine an additional suction point at
the camshaft bed.
SCHALLER AUTOMATION recommends a final test procedure per engine
type called OMDEA (Oil Mist Detection Efficiency Approval).
According to the IACS unified requirement M10 the installation drawings have to be
approved from engine builder and SCHALLER AUTOMATION. The installations have
to be executed in compliance with these drawings and the contents of this manual.
Important: As an engine maker, you need a Declaration of
Conformity from the OMD maker
