1 Introduction 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
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.

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.

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.

Figure 4: Optional Remote Indicator II

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.

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.

2 Installation 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.

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.

o VN115 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.

o VN115 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.

2.2 Electrical installation

2.2.1 VISATRON® VN115/87plus EX device

The electrical terminal is inside the socket housing (see Figure 16) on the base
plate of the VISATRON® device. The pin assignment is specified in Figure 19. The
cable entry points are located on either side.

According to the pin assignment of Figure 19 connect the VISATRON® device to
the 24 Volts power supply. The supply voltage can be potential free or not. The
earth connection between the OMD and the engine is carried out by the fixings
screw of the base plate or protection cover.

Additionally connect one alarm relay output to the safety system of the engine. As
specified by the classification societies the 'Alarm' relay must be connected either to
the shutdown or to the slow-down input.

During normal operation the alarm relay is switched off. In case of an oil mist alarm
the relay is switched on. To monitor this output, a wire break resistor is installed

(between pin 7 and 8 and between 15 and 16 as shown in Figure 19).

To replace the wire break resistors the measuring head has to be dismounted. The

resistors (see Figure 18) are located on the rear side under the plastic cover (see
Figure 17). The plastic cover can be removed via the screws. Do not forget to write

the resistor value on the plastic cover with a permanent marker.

Also placed on the rear side two jumpers are available to select the interface mode:
RS485 bus or 4- 20mA output of the relative opacity at pin 11 and 13.

Second 'Alarm' output and 'Ready' output must be connected to separate channels
on vessel’s or power plant’s alarm monitoring system. The 'Ready' relay is switched
on when OMD is in correct operation (see Figure 19).

The optional pre-alarm output can be used to initiate either a pre-warning signal or
slow-down signal. The pre-alarm relay is switched on when the oil mist
concentration has risen up to 70% of the Oil Mist alarm level. Please note that
depending on the characteristics of an oil mist occurrence, the time between 'Pre­alarm' and 'Main Alarm' could be only a fraction of a second.

2.2.2 Connection of monitoring devices

As required by IACS UR M10 the OMD device can be connected to Schaller's remote
monitoring device Remote Indicator II to monitor the oil mist concentration and the
OMD status from a safe location.

The connection to the monitoring device is accomplished via a RS485 two-wire bus.
In case of a Remote Indicator II the connection is only a two point link. The bus
system at the OMD device must be terminated by the resistor. It is integrated in
the terminator (see Figure 21), which is supplied with the monitoring device.

The used communication cable must be twisted pair and shielded. We recommend
LAPPKABEL UNITRONIC-FD CP (TP) plus UL-CSA, AWG20. The total bus length is
limited to 400 m. The VISATRON® device cable entry (see Figure 20) at the
VISATRON® device is designed for cable diameter between 7.5 and 10.0 mm.

The connection between the OMD device and the monitoring device for standard

applications is shown in the following wiring diagram (see Figure 21)

3.4 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 of 25 °C. IACS UR M67 rules do request that OMD’s do indicate an oil
mist alarm latest at approx. 2.5mg/l. The lesser sensitivity level of all VN/87plus

OMD’s, level 6, still ensures an Oil Mist Alarm at oil mist concentrations inside the

engine of <2.5mg/l. This complies fully with the requirements given by the IACS
UR M67.

Table 2: Sensitivity switch position and corresponding oil mist alarm level

The sensitivity of the VISATRON® oil mist detector can be adjusted by a switch on
the rear side of the measuring head (see Figure 29).

5.7 Measuring head fuses

The device has two internal fuses. The first is located in the main connector of the
measuring head. This is a ‘self-repairing’ fuse which protects the filter circuit in the
connector.

To reset this fuse, unplug the main connector and wait 5 minutes before you plug
it again.

If all LED’s remain off exchange the 2A semi lag fuse II at the rear side of the
measuring head (see Figure 46).

WARNING!
Unplug the main connector during welding work around the
engine or in engine room!

Page 45

In case all LED’s remain off despite fuses are ok, perform check as shown in Figure

47. Often it happens during welding work around the engine or in engine room that

electrical current of high energy passes through detector and its electrical wiring.

As a result, possible bursts and peaks may cause damage inside the measuring
head. In that case, only a replacement of the measuring head helps.

7 Functional test

7.1 On board test

By using the VN Smoke Test-Box you can easily test the functionality of the
VISATRON® oil mist detector and its connection to the safety system of the engine.
The set can be ordered separately under Part.-No. 151780. It consists of the
following parts:

Test procedure step by step:

Operation Manual VISATRON® VN115/87plus EX 06/2016

Step 3

Add the flexible hose.

Step 4

Mount the smoke tube and hand pump and then
add them to the flexible hose.

Step 5

Use the hand pump to generate smoke (it may
work even without the pump

Step 6

Wait for the 'Alarm'-LED. At this comes on, the
engine has to stop or to enter the slowdown mode

Step 7

Dismount the test equipment and carefully
reinstall the lock screw.
Caution! Do not forget the gasket underneath
the lock screw, otherwise you will risk a mixture
of explosion zones!

Always use a new gasket for the lock screw
after removing for testing!

Step 8

Wait for the 'Ready'-LED.

Step 9

Press the Oil-Mist-Alarm RESET button to
acknowledge the alarm state and enter the
normal monitoring mode.

If LED14 is blinking and the Oil-Mist-Alarm RESET button is
pressed the OMD device enters a test mode. In this test
mode the LED bar displays the measured opacity. After
pressing the Oil-Mist-Alarm RESET button again the OMD
device exits the test mode and LED14 is blinking again.

Attention: Always use a new gasket for the lock screw after
removing it for testing! (Step 7)

Page 48

If applicable perform an additional pressure measurement to check the tightness of
the suction system as described in chapter 7.3. Instead of an electronic gauge you
can use the U-pipe manometer of the service box.

Attention: Before starting the on board test execute the
procedures as specified in the maintenance schedule. The
pipe system has to be clean and if used all siphons have to

be filled with oil refer to chapter 2.1.3.

7.2 Factory test at engine builder with smoke generator on

VN115/87plus EX installations

Due to vessels not normally having the equipment and SCHALLER AUTOMATION
recommends this procedure only for the factory test by using the SCHALLER smoke
generator (see Figure 49). If a smoke generator is available on a vessel, this test
can be also performed. However, in this case observe the following warning.

A test of the entire OMD system (incl. tubing system) can be done only at standstill
of the engine. The crankcase service covers must be opened first. Put a small

amount of smoke fluid (see Chapter 'Accessories') into the reservoir and switch on

the generator for a few seconds until the storage tank is completely filled with
smoke. The last step is to hold the flexible hose directly into the suction funnels
until an oil mist alarm is indicated.

If it's not possible to open the service covers a functional test can be performed
without testing the suction funnels.

In this case the flexible hose has to be pressed over the opening under the lock
screws of the siphon blocks as seen in Figure 50 or has to be pressed over the
open header pipe end after removing the lock nut.

7.3 Additional pressure measurement on VN115/87plus EX installations

Perform the functional and smoke test as shown in the previous chapters 'On board
test' and ‘Factory test with smoke generator’.

Then carry out a pressure measurement at the end of the suction system. The
engine including the oil pump must be at standstill.

Minimal suction pressure at the far left and right end of the suction tubing system

VN115/87plus EX >6.5 mmWC

Figure 53: optional Fog machine

Figure 54: optional Fog bag adapter

Page 51

On a VN115/87plus EX installation the tightness of the suction system can be
determined by a pressure measurement at the outer siphon blocks or at the end of
the header pipes.

This siphon block has an additional fitting for a manometer (see Figure 51). To

remove the 17 mm lock nut you have to counter the 19 mm nut with a jaw wrench.

The pressure measurement procedure can also performed at the end of the 22 mm
diameter suction pipes which are delivered from SCHALLER AUTOMATION. These

pipes have also fittings for the manometer at the pipe end (see Figure 52).

Use only a digital manometer with a differential measuring method. On completion
do not forget to lock all openings.

The minimal negative pressure values are defined in the table below. They are only
valid if a negative pressure of 60 mm WC is adjusted at the measuring head.

7.4 Factory test at engine builder with fog machine on all installations

This test includes the indication of an oil mist alarm as well as the indication of the
affected compartment. Instead of the above mentioned smoke generator you have
to use the more powerful fog machine (see Figure 53) with a fog bag with adapter
(see Figure 54).

This equipment guarantees a constant fog concentration during the test and due to
high density no influence of the additionally sucked in crankcase atmosphere.

Operation Manual VISATRON® VN115/87plus EX 06/2016

Attention: Let in fog at sampling points of all compartments
including chain/gear drive.

Figure 55: Test fog inlet on the siphon blocks

Lock screws

Page 52

Due to the increasing request of the ship owners and classification societies to test
the OMD-System at running engines SCHALLER AUTOMATION recommends now
following procedure.

The first test must be performed at standstill to secure, that the engine is well
protected by the OMD system. If it is not possible to open the service covers or if it
is not possible to access the suction funnels, e.g. on large 2-stroke engines, a
functional test can be performed alternatively using a special connection on the
siphon block or respectively on the T-engine wall connection.

Fill the fog bag completely with fog and close the adapter with the yellow cap. The
next step is to press the flexible hose of the fog bag adapter over the opened plug
at the side of the siphon blocks as seen in Figure 55 or over the open tube end at
T-engine wall connections. Do not remove the hose until an oil mist alarm is
indicated and the search run to indicate the affected compartment is finished. The
plugs can be countered by an 11 mm jaw wrench to open or close the lock screw.

The second test can be performed on request at running engine using the plugs of
the siphon block or the T-engine-wall connection to induce the fog.
