1.0 Introduction

The 3SEP OWS is an oily bilge water separation system designed to separate
free/emulsified oil from the bilge water and check that the oil residues in the
treated water do not exceed 15ppm before discharge overboard. The 3SEP
OWS complies with IMO Resolution MEPC 107(49). According to MARPOL
73/78 all vessels above 400 DWT require an approved bilge water separator
and alarm.

The system is available in four different capacities;

1.0m3/h, 2.5 m3/h, 5.0 m3/h and 10.0 m3/h. This manual contains the
instructions for operating all four models.

The treated water released by the 3SEP OWS contains not more than 15-
ppm oil in water. The system has been designed to meet the
requirements prescribed by IMO MEPC 107 (49).

For bilges with heavily emulsified oil in the bilge water a 3SEP OWS coupled to
a JOWA EBU (Emulsion Breaking Unit) offers the best solution and ensures
treated water under 5ppm. The 3SEP OWS is supplied standard with the
necessary inlet for connecting a JOWA EBU. For additional information about
the EBU system contact JOWA.

1.1 General

1.2 System

Overview.

The 3SEP OWS is designed for a continuous flow with automatic operation, the
system does not require any chemicals. The following text gives an overview of
the 3SEP OWS separation process and the 3SEP OWS general arrangement.

The first stage removes the free oil by gravity. An adjustable oil sensor controls
the pneumatic valve for automatic oil release to the sludge tank or any other
dedicated tank. The adjustable oil sensor makes it possible to minimise the
amount of treatable water released to the sludge tank.

In the second stage emulsified oil is removed in the two filter tanks and the ppm
value is monitored continuously by an oil content meter before the treated water
is discharged overboard.

The collected free oil on top of each filter tank is released automatically to the
sludge tank at a preset interval. When a 15 ppm alarm occurs, the 3SEP OWS
will automatically close the overboard line and re-circulate the treatable water to
the bilge. When the contamination falls below 15 ppm the valve for overboard
release will open again without human intervention.

The system is designed as a compact skid assembly with all connection points
collected, for easy “Plug n’ Play” installation. When the unit reaches the
customer the only remaining thing to do is to connect water inlets/outlets, the
electrical power supply and air connection, facilitating quick and easy
installation onboard.

Before leaving our workshop each unit has to pass a quality-test, where
all functions are tested and checked.

All equipment has the highest quality; the tanks are made of acid proof stainless
steel, AISI 316L. Our pumps are supplied by internationally recognised brands.
Spare parts are easily available from one of our offices or representatives
worldwide.

NOTE! Before filling check that the internal strainers are carefully
fastened.

Fill the tanks T2 and T3 through the upper hatches to 60-70 % of the tank
volume, approximately 10-15 centimetres below the upper strainers. When the
tanks are filled with filter media mount the upper hatches and back flush each
filter one by one for at least 10 minutes until clean fresh water is coming through
the sample valves V18 and V19 (See Chapter 6.1 for detailed back flushing
instructions). The amount of back flushed water should be at least 3 times the
volumes of the filters. We recommend back flushing with fresh water at a
pressure of no more than 6 bar. Maintain low water pressure and speed
during back flushing to avoid losing filter media from V18 and V19. Throttle
V15 and V16 to control water speed and pressure during back flushing.

4.0 System

Function.

This chapter provides a detailed description of the unique functions of the 3SEP
OWS. The material provided in this chapter gives the operator the possibility to
gain an excellent understanding into how and why the 3SEP OWS performs its
functions. It is intended that the information in this chapter may be used to help
the operator optimise the 3SEP OWS performance to his or her specific bilge
requirements.

4.1 Normal Flow Through the 3SEP OWS (See Flow Diagram)

Normal flow through the 3SEP OWS.

The separator consists of three (3) tanks connected in series, tanks T1-T3, and
the oil content meter. Tank T1 utilises specific gravity to separate and release
free oil. Tanks T2 and T3 are filters utilising the filter media JOWA F - 200 C to
remove the majority of the remaining emulsified oil. Finally the oil content of the
treated water is checked by the oil content meter before it is discharged
overboard.

The bilge water is initially pumped into the top of T1 thru valve V10 where most
of the free oil is gathered in the release pipe. When the oil senor CT03 detects
oil it is released through the pneumatically controlled valve V01 and is delivered
to the concentrated sludge tank.

The partly treated water is then pumped out of the bottom of T1 through the two
filter tanks T2 and T3 connected in series. The pneumatically controlled valves
V02 and V03 release the free oil at the top of T2 and T3 to the concentrated
sludge tank.

At the outlet of tank T3 the oil content in the treated water is checked by the oil
content meter. The valve V20 shall be in open position. The treated water flows
through the pneumatically controlled valve V04 for overboard discharge.

If the oil content of the flow coming from the outlet the 3SEP OWS exceeds
15ppm the pneumatically controlled valve V04 closes and the pneumatically
controlled valve V05 opens, re-circulating the discharge from the 3SEP OWS
to the bilge. When the oil content detected by the oil content meter falls below
15ppm again V05 will close, V04 will open and overboard discharge will
resume.

If during re-circulating there is no flow through the sample outlet line of the bilge
alarm adjust flow restrictor FR01.

The recirculation cycle occurs for 20 minutes and is adjustable (See Chapter 5).
If the treated water remains above 15ppm at the resumption of normal flow after
the recirculation cycle, the 3SEP OWS will stop and an alarm will occur. The
3SEP OWS can be back flushed and restarted. See Chapter 6.1 for back
flushing instructions.

4.3

Oil Release from 3SEP OWS (See Flow Diagram)

Oil Release occurs at three points on the JOWA 3SEP OWS; T1, T2 and T3.
The released oil should be delivered to a suitable tank such as the concentrated
sludge tank. The flexibility of the 3SEP OWS oil release system allows a high
degree of control over the oil release.

In the first stage, tank T1, oil release is controlled by an oil sensor, CT03. The
sensitivity of the oil sensor CT03 is operator adjustable in order to minimise the
amount of treatable water released from T1. To adjust the sensitivity of the oil
sensor CT03 see chapter 5.3 and 5.6.

The oil accumulates in the top of T2 and T3 as the partly treated water is
delivered from T1. Oil release from the filter tanks T2 and T3 occurs
automatically. This oil is released by the pneumatically controlled valves V02 on
tank T2 and V03 on tank T3. The time length interval between oil releases for
V02 and V03 is fixed.

Oil is released from V02 every five minutes, for a time period of 20 seconds
(adjustable). Oil is released from V03 every hour for a fixed period of 5 seconds.
When the JOWA 3SEP OWS is started an automatic oil release from V02, and
V03 occurs for a fixed period of 3 seconds. This ensures that the pure oil that
has gathered at the tops of the tanks while the unit has been stationary is now
released.

4.3.1 High Level Start Switch

Automatically starts the 3SEP OWS when the bilge water level is high, using a
level switch located in the bilge tank.

4.3.2 Low Level Stop Switch

Automatically stops the 3SEP OWS when the bilge water level is low, using a
level switch located in the bilge tank..

4.3.3 Dry Running Protection

Protects the 3SEP OWS pump from running dry.

4.3.4 Prime

4.4

Optional features on the 3SEP OWS.

The following are optional features for the 3SEP OWS:

4.4.1 Bilge Clean Mode (Optional)

Bilge clean mode gives the operator the flexibility to run the 3SEP OWS while
docked in the harbour. In bilge clean mode no treated water is released
overboard but constantly re-circulated to the bilge.

In bilge clean mode the flow from the bilge only passes through the first stage
tank T1 and then returns to the bilge tanks. The bilge water is pumped into the
top of T1 thru valve V10 where most of the free oil is gathered on the
coalescence surfaces. When the oil senor CT03 detects oil it is released
through the pneumatically controlled valve V01 and is delivered to the
concentrated sludge tank. The flow then passes through V13 and returns to the
bilge.

Running in bilge clean mode allows the maximum amount of free oil to be
removed from the bilge water before it passes through the filter tanks T2 and
T3, maximising the life of the JOWA F - 200 C filter media.

4.4.2 Transfer Mode (optional)

Some vessels have more than one bilge tank. Transfer mode uses the 3SEP
bilge pump to pump between these different bilge tanks without flow passing
through the 3SEP.

4.4.3 3SEP OWS with JOWA Emulsion Breaking Unit EBU (Optional)

A JOWA EBU system may be coupled to the 3SEP OWS as an extra treatment
stage. The JOWA EBU 3SEP OWS package can achieve treated water with
less than 5ppm oil in water.

It is strongly recommended that the operator consider a 3SEP OWS coupled
with JOWA EBU if the bilge water contains high levels of emulsified oil. The
JOWA EBU is a chemical treatment of the emulsified oil in water. The chemical
is a flocculent that helps the small particles of oil coalesce together and thus
separate by gravity.

The 3SEP OWS skid is ready supplied with the connection for a JOWA EBU

5.0 Operation

This chapter gives the operator detailed information on how the major control
components of the 3SEP OWS are operated and adjusted.

5.1 General

General operation of the 3SEP OWS is facilitated by the PLC user interface and
the switches located on the door of the main control box. All of the electric and
pneumatic control equipment is located on the control cabinet stand at the side
of the 3SEP OWS skid frame. Before delivery all electrical equipment on the
unit is connected and thoroughly work-shop tested.

x All electric equipment is connected to the main control box and the 3SEP

OWS is operated from here. The main power switch, S1, for the 3SEP OWS
is located on the side of the main control box.

x The electronic parts for the oil content meter are located inside the oil content

meter control box.

x The pneumatic solenoids for the pneumatic control valves are located on the

side of the 3SEP OWS skid frame control stand

5.2

Start/Stop the 3SEP OWS

After the actions in section 3.9 ‘Initial Start-up Checklist’ have been completed
the unit can be started and run in normal operation.

5.2.1 Start/Stop Manual Mode

Turn on switch S0, ‘power on’. Turn switch S2 to position 1 for Man mode. The
3SEP OWS will run in auto mode. The 3SEP OWS first runs through a start
routine before normal flow commences. In the start routine oil is released from
all tanks by means of the pneumatically controlled valves V01-V03 opening for
a short period. To stop the 3SEP OWS simply switch S2 to position 0.

5.2.2 Start/Stop Auto Mode

In this mode the 3SEP is started by the high/low level switches located in the
bilge tank described in the previous chapter

5.2.3 Start/Stop Bilge Clean Mode (optional)

Turn on switch S0, ‘power on’. Turn switch S2 to position 2 for bilge clean
mode. The 3SEP OWS will run in bilge clean mode. To stop the 3SEP OWS
simply switch S2 to position 0.

5.2.4 Start/Stop Transfer Mode (optional)

Transfer mode can be operated in both auto and manual mode. However, the
operator must exercise caution and see that the manual ball valves between the
bilge tanks are in the correct position for transfer mode function correctly.

5.3

The PLC User Interface

The PLC user interface facilitates the running and understanding of the 3SEP
OWS. Through the user interface and display on the main control cabinet door
you receive all messages concerning the 3SEP OWS such as operational
status, alarms, and pre-set times.

5.4

The Oil Content Meter

The oil content meter is located on the control cabinet stand on the 3SEP OWS
skid. The oil content meter door displays the oil content in PPM in the water
being discharged from the 3SEP OWS. The alarm limit for the oil content is
adjustable between 0 - 15 PPM. The oil content in the water is measured by the
sensor unit located to the right of the oil meter electric control box. If there is no
flow through the oil content meter the reading will be corrupt and the oil content
meter will register an alarm. A complete Technical and Operation manual for the
Oil Content Senor will be included in the oil content meter chapter of this
manual.

5.5

The Pneumatic Solenoid Control Valves

The pneumatic solenoid control valves control the valves V01 to V05. Each
pneumatic solenoid control valve is marked with the valve position number. The
air pressure to the solenoid control valves must be 4-6 BAR dry instrument air
to get a proper function and performance of the valves.

5.6

Oil Sensor CT03

The oil sensor, CT03, measures the capacitance between the sensor rod and
the pipe wall. The index of the oil sensor varies from 2 to 100, where 2 is air and
100 is water (oil has a value of 2-20). The factory set point value is 80. The set
point of CT03 may be adjusted by the operator to suit the amount of free oil in
the bilge water. For example a lower set point value on CT03 may suit a bilge
with high amounts of free oil. Lowering the set point value has the advantage of
decreasing the amount of water released to the concentrated sludge tank.
However lowering the value may also shorten the lifespan of the JOWA F – 200
C filter media, as it must absorb more oil. Conversely, raising the value will
result in more water being released to the concentrated sludge tank but a longer
filter media lifespan. The sensor rod has to be cleaned regularly to ensure its
correct function, See chapter 6 for cleaning instructions.

6.0 Maintenance

This chapter provides detailed instructions for common maintenance operations
on the 3SEP OWS. A regular maintenance timetable is also included. The
timetable is designed to aid the operator in scheduling minor periodic
maintenance tasks thus avoiding unnecessary breakdowns.

6.1

Back flushing Procedure for Filter Tanks T2, T3.

It is necessary to back flush the filter tanks T3 and T2, in that order:

x After

JOWA F - 200 C is installed at start-up

x The oil content meter gives an alarm indicating an oil content exceeding 15

ppm for a period of extended time or

x After changing the JOWA F - 200 C filter media as part of regular service,

approximately once a week.

Proceed as follows:

1. Switch off the unit, close the valve V10 (and V11 if 3SEP OWS is connected

to a JOWA EBU).

2. Make sure that the pressurised fresh water is available at the valve V12
3. Start the back flushing of filter tank T3 by opening the valve V12 carefully.
4. Open valves V16 and the 3-way valve V30, carefully monitor the pressure.

Do not fully open V30 immediately, open it slowly, allowing the flow to
build pressure slowly. This avoids flushing away the JOWA F - 200 C filter
media from the sample points V18 & V19. It also avoids damage to the
pneumatic and non-return valves from flushing the JOWA F - 200 C filter
media into them.

5. Be sure that V30 is allowing the flow to pass thru T3. You may check this by

observing the outlet pressure at V19

6. Check the water quality through the valve V19.
7. Back flush until the water is clean, usually three times the volume of the filter

is the required amount of water for back flushing (5-10 minutes for each
filter).

8. Close the valves V12 and V16 and V19.
9. Start the back flushing of filter tank T2 by opening the valve V12 and then

valve V15 and the 3-way valve V30. Again, Do not fully open V30
immediately, open it slowly, allowing the flow to build pressure slowly.

10. Be sure that V30 is allowing the flow to pass thru T2. You may check this by

observing the outlet pressure at V18

11. Check the water quality through the valve V18.

JOWA 3SEP OWS

OILY WATER SEPARATOR

K:\1-NYA K\1-JOWA PRODUKTER\3SEP\Manual

27/41

12. Back flush until the water is clean, usually three times the volume of the filter

is the required amount of water for back flushing (5-10 minutes for each
filter).

13. Close the valves V12 and V15 and V18.
14. Back flushing is complete.

6.2

Changing JOWA F - 200 C Filter Media in Filter Tanks T2, T3.

The filter media must be changed at least every 12-24 months. This section
describes the procedure for changing the filter media.

6.2.1 Removing the Filter Media

NOTE! When removing filter media, make sure that you do not damage internal
filter tank strainers. The strainers are located in the top and bottom of T2 and
T3, see mechanical drawings chapter 9.

x Stop the 3SEP OWS at the main control box, close V10 (and V11 if 3SEP

OWS is connected to a JOWA EBU).

x Open the filter tanks bottom valves V15, V16 and V14 to drain the water from

the filter tanks.

x Open the sample valves V18 and V19 to let air into the top of the tanks.
x Remove the upper hatches and wait until the water flow at the bottom has

stopped.

x Open the lower hatches and empty the tanks of filter media.

Clean the tanks carefully inside and check that the internal strainers are
undamaged and free of carbon and oil. Check the zinc anodes and change
them if more than 70 % of the zinc has corroded.

6.2.2 Filling the Tanks T2, T3 with Filter Media

NOTE! Before filling check that the internal strainers are carefully
fastened and undamaged. Should the strainers be damaged replace them.
See chapter 17 Spare/Consumables Parts List. Fill the tanks T2 and T3 through
the upper hatches to 60-70 % of the tank volume, approximately 10-15
centimetres below the upper strainers. When the tanks are filled with filter
media mount the upper hatches and back flush each filter one by one for at
least 10 minutes until clean fresh water is coming through the sample valves
V18 and V19 (See the previous section of this chapter for detailed back flushing
instructions).
NOTE! For guaranteed function we recommend the JOWA F - 200 C filter
media.

Standardtype
Ventil in Ruhestellung geschlossen - (NC). Bei erregtem Magnet baut
sich die Druckdifferenz von der Sekundärseite der Membrane über
die Servobohrung ab. Die wirksame Druckdifferenz hebt die
Membrane vom Ventilsitz ab. Der angegebene Mindestdruck muß
als Druckdifferenz für eine einwandfreie Funktion der Servosteuerung
immer vorhanden sein.

Valve normally closed - NC.
When energised, the pressure decomposes on the secondary side
of the diaphragm via the pilot hole. The pressure differential lifts the
piston from the seat. The stated minimum pressure is always
necessary as pressure differential for accurate operation.

IMPORTANT NOTICE

Replacement components for 15ppm Bilge Alarms.

General

All monitors in our range are inspected and tested to the related I.M.O. requirements at
our factories prior to delivery.

In normal use the units should operate correctly and without fault over a long period of
time requiring only small amounts of maintenance to be carried out as outlined in the
instruction manuals.

Service Exchange Units

In the event of a monitor malfunction due to electrical or electronic component failure it
is our recommendation that a service exchange unit be ordered.

The defective instrument should be returned to our works within 30 days of supplying
the service exchange unit, then only the repair charge is payable. Otherwise the whole
cost of a service exchange unit becomes payable.

This procedure is by far the easiest and most cost effective way of ensuring the monitor
on board conforms to I.M.O. resolution MEPC.107 (49).

Remark:

According the MEPC.107(49) § 4.2.11 the unit has to be checked at IOPP Certificate
renewal survey by the manufacturer or persons authorized by the manufacturer.
Alternatively the unit may be replaced by a calibrated 15 ppm Bilge Alarm. The OMD-
2005 is designed in that way, that only the measuring cell needs to be changed, as this
unit carry the calibration onboard. The Calibration Certificate with the date of the last
calibration check should be retained onboard for inspection purposes.

If for some reasons the computer unit needs to be changed, it has to make sure, that
the memory card will remain on board for at least 18 month. The new computer unit will
carry its own memory card. The old card can be insert into the new unit only for reading.
Writing is only possible with the card delivered with the new computer unit. For details
see section 13.1.

INTRODUCTION

The OMD-2005 Bilge Alarm Unit has been designed specifically for use in
conjunction with 15 ppm oil-water separator units and has a specification and
performance which exceeds the requirements of the International Maritime
Organization specifications for 15ppm Bilge Alarms contained in Resolution
MEPC. 107 (49).

The unit is supplied with 2 works-adjusted alarms at 15 ppm. Other set points
(10 ppm or 5 ppm) are possible and can be adjusted on site at any time by using
the buttons at the front panel.

If an alarm set point is exceed, the alarms are visible at the front panel and the
appropriate relays are switched. In case of malfunction the System LED at the
front panel will change from blinking green to permanent red and the appropriate
relay will switch the contacts.

For the data logging function the unit requires an status input from the separator
and a feedback signal from the valve position limit switch. (See Fig. 1, Pos.6)

Furthermore a 0(4) - 20 mA (equal to 0 - 30 ppm) signal output is available for
driving a recorder or external meter.

PRINCIPLE OF OPERATION

3.1

Measuring Principle

An optical sensor array measure a combination of light scattered and absorbed
by oil droplets in the sample stream. The sensor signals are then processed by a
microprocessor to produce linearised output.

If an alarm (works set point 15 ppm) occurs, the two oil alarm relays are activated
after the adjusted time delay.

The microprocessor continuously monitors the condition of the sensor
components and associated electronics to ensure that calibration accuracy is
maintained over time and extremes of environmental conditions.

3.3

Adjustment

The unit is delivered with a works calibration according the IMO-requirements.
The alarm points are set to 15 ppm.

The "Zero" point is also works calibrated and can be re-adjusted on site by using
the programming mode and clean water. See Section 10.4 “Service-Offset”. A
calibration is not permitted. This has to be done according IMO Regulations by
the manufacturer or persons authorized by the manufacturer.

3.4

Displays and Alarms

In the unit are two independent oil alarm circuits available. Both can be set
separately from 1 to 15 ppm. From the manufacturing both alarms are set to
15 ppm (according IMO). The set points can be changed according to the
requirements on site, for example to 10 ppm or 5 ppm. An alarm point setting
above 15 ppm is not possible. The adjustment can be done in the programming
mode as described in Section 10.4.

In this mode also the individual adjustment of the time delays for the alarms and
the possible changing between 0 - 20 mA or 4 - 20 mA output can be done.

DECKMA HAMBURG GmbH

Both alarm circuits are also related to an alarm LED on the front panel.

In case of malfunction the “System” LED will indicate any type of internal fault of
the unit. This LED is flashing green in normal conditions and is red in alarm
conditions. Also this alarm is related to an relay output.

Additional to the alarm LED's each alarm circuit is equipped with a relay with
potential free alarm contacts. These contacts can be used for external processing
of the signal or for control of further functions.

If a malfunction or failure of the power supply occurs, all 3 relays will switch to
alarm condition.

CONSTRUCTION

There are 3 main parts which contained in an OMD-2005:

The computer unit is mounted into an epoxy powder painted steel housing
to protect the electronics of the display PCB with the data logger and the
main board PCB with the terminals for external connections.

The measuring cell is built out of an anodized all-aluminium body with inlet
and outlet block in stainless steel. This rugged cell contains the optical
electronic and correspond with the computer unit via a plugged data cable.

The valve assembly contains a special handle to sense the position of the
valve. This assembly is connected to the measuring cell by an easy to
handle fitting to enable the exchange of the cell for frequently adjustment
according the IMO requirements.

All components are mounted to a stainless steel mounting plate for easy wall or
bulkhead installation. It is also possible to split the computer unit from the
measuring cell if the available space is not sufficient. For this version divided
mounting plates are available.

INSTALLATION

(Refer to Fig. 2 and Fig. 3)

See Section 2 for important notes concerning installation.

The OMD-2005 Monitor should be located as close as possible to the oily water
separator to minimize response delays. According MEPC.107(49) the layout of
the installation should be arranged so that the overall response time (including
the response time of the 15 ppm Bilge Alarm) between an effluent discharge from
the 15 ppm Bilge Separator exceeding 15 ppm, and the operation of the
Automatic Stopping Device preventing overboard discharge, should be as short
as possible and in any case not more than 20 s.

Mount the OMD-2005 Monitor by means of 6 x M8 screws on to a rigid vertical
surface and preferably with the display panel of the monitor at eye level. For
service and maintenance sufficient space to all sides should be available.

Care must be taken at mounting of the pipes connections to avoid any torsion of
the housing and damage of the instrument.

PIPING

(Refer to Fig. 3)

Connect the OMD-2005 Monitor to the sample point of the oily-water separator
outlet and to a source of oil free water employing 10 mm OD copper or stainless
steel pipe. The sample point should be located on a vertical section of the
separator outflow piping to minimize the effects of any entrained air. The tapping
point should be at a level above the outlet of the monitor to ensure the sample
cell is flooded at all times.

If connection to a vertical section of the separator outlet piping is impractical, the
tapping may be made into the side of the horizontal pipe. Avoid top or bottom
entry.

For separator discharge pipes up to 75 mm OD a standard "T"-type junction of
the welded or screwed type is satisfactory for the tapping point. For the separator
discharge pipes of 80 mm OD and above a sample probe should be employed
which protrudes into the discharge piping by approx. 25 % of the ID of the pipe.

WIRING

(Refer to Fig. 4 + 5)

See Section 2 for important notes concerning wiring.

This unit must be connected to the mains supply via a suitable rated and
approved fused isolator unless such fusing / isolation is provided by associated
equipment. When fitted, the isolator should be close, readily accessible and
marked as to function.

Electrical connections are made through the metric cable gland openings
prepared underneath the instrument.

Fig. 4

Precise wiring details will vary dependent upon the control system to be
employed but the most frequently used systems employ alarm relay 1 for alarm
only and alarm relay 2 for control purposes.

Electrical connections are made to the terminal blocks inside the computer
housing. Wires are connected to the terminals by pushing a suitable screwdriver
into the clamp holes to release the internal spring loaded clamps. After the wire is
inserted to the terminal and the screwdriver is removed, the wire is fixed.

If the instrument is operated at high voltages, additional care has to be taken to
provide reliable ground connections. Ground (PE) can be connected direct to the
terminal or, if this is not sufficient according local rules, to the computer housing
left side. In this case the plug needs to be replaced by a M6 screw with nut and
related washers.

The instrument provides a pilot voltage output at terminals 4&5. This is internally
connected to the power supply input (Terminals 1&2), but is fused by Fuse F1 (2
A). The pilot voltage can be used to supply additional external circuitry, e.g. alarm
lamps or electrical valves.

Please note: any device connected to the pilot voltage output must be rated for
the voltage the instrument is supplied with. Do not use the pilot voltage for driving
motors, heaters or other high load devices. The pilot voltage is intended for alarm
purposes only.

8.1

Typical Control System

The installation on site has to make sure that in case of any loss of power supply
and/or loss of air supply for the automatic stopping device the overboard
discharge valve close the overboard line and open the re-circulating line.

The system showed in the example, employs alarm relay 2 to control a
pneumatic solenoid valve which energises or de-energises a pneumatically
operated 3 - way valve as depicted in Fig. 5.

The separation process will continue until such time as the pollution level falls
below the alarm set point at which time the discharge will be directed overboard.

A pump stop system is according MEPC.107 (49) not allowed.

9.0

POWER SUPPLY

See Section 2 for important notes.

The unit is designed for a power supply of 24 V to 240 V AC or DC. It has an
automatic power selection.

10.0 COMMISSIONING

See Section 2 for important notes.

On completion of the installation, wiring and piping carry out the following checks:

10.1

Electrical

a) Check that the power supply is connected to the terminals 1 + 2 of the

terminal block.

b) Check the wiring of the automatic stopping device and to the alarm system is

according the IMO Requirements.

c) Check that the grounding has been made according to the relevant

regulations.

10.2

Piping

a) Check all piping connections for leaks and rectify as appropriate.

DECKMA HAMBURG GmbH

Issue: 12.11.04

Instruction Manual OMD-2005

Page 14 of 24

10.3

Functional Tests

a) Run oil free water through the instrument to purge the system.

b) Adjust the flow rate through the unit by using the small screws in the cell cap

(Fig. 1, Pos. 2). Taking out a screw will increase the flow rate.

NB: The flow rate should be checked on both, the clean water supply and the
separator sample supply. If the clean water supply is obtained from a high
pressure source, the flow rate will be higher than from the sample point.

The flow rate is not influencing the accuracy of the instrument. The adjustment
is only important for the time delay between the sample point and the monitor.

c) Switch on the instrument and make sure, that the Power LED is illuminated

and the display is showing the
initializing display for about 15
sec. After that time it will
change to the standard display,
showing the actual
measurement.

d) During oil free water is running through the monitor check the Zero adjustment

according Section 11. The display should be "0" to “2” and the status will show
“FW”. If the display varies by greater amounts, it may be that air entrainment is
present. If this is the case, the cause must be located and rectified.

f) If the Zero need to be adjusted, this can be done in the programming mode as

described in section 10.4. (Service – Offset)

e) Remove the Cell Cleaning brush and replace the cell cap.

f) Reconnect the oil free water supply and allow this to flow through the

instrument for a few minutes.

g) Observe that the display is showing "0" to “2”. If not, clean again.

h) Examine the color of the desiccator (Fig. 1, Pos. 11). Blue color is indicating

an active moisture absorber. If the color is light blue or white, the desiccator
should be replaced.

The desiccator assures a humidity below 40% inside the measuring cell to
avoid wrong measurement resulting due to condensation at the cell glass tube
and damage of the electronics around the glass tube. The replacement is easy
done without opening the instrument. Just unscrew the old desiccator out of
the front panel and replace it by a new one. The protection cap of the spare
unit can be also used as a tool.

j) Reconnect the instrument to the separator sampling point.

Manual Cell Clean Unit

Optional item if fitted

This unit facilitates cleaning of the cell without the need of removing the cell cap.
Regular use of this device should prevent malfunction of the monitor due simply
to fouling of the sample tube and all the inconvenience which this can cause.

Operating Instructions

a) Ensure that the monitor is switched off and that there is a clean water supply

through the cell.

b) Activate the manual cell clean unit by pressing the handle several times.

c) Switch the monitor back on and check the reading is between 0 to 2 ppm.

d) Repeat a) to c) at least once a week or as necessary.

NB: The Manual Cell Clean Unit may also be used during normal operation with
sample water, but in this case an alarm occurs because the wiper is passing the
light source.

Memory Card (refer to Fig. 6)

The Memory Card is located inside the door of the computer housing. It is
suitable for the life of the instrument, as it is calculated to the according MEPC
107(49) required storage time of at least 18 month. When the card is full, the
oldest entry will be overwritten, so that a replacement is not necessary. Under
normal use the card should not be taken out, as this is linked with the specific
system. The card can be read in other OMD-2005 units, but writing is only
possible in the related system.

14.0 CALIBRATION

15 ppm Bilge Alarms built according MEPC.107(49) have to be protected against
access beyond the checks of instrument drift, repeatability of the instrument
reading and zero adjustment. For this reason the instrument is electronically
sealed, so that only the manufacturer or his authorized persons, equipped with
the related tools, are able to get access for changing the calibration.

To provide a simple procedure for check the instrument aboard ship, the OMD-
2005 is constructed in that way, that the zero check also confirms the instrument
drift within the specifications.

14.1

Calibration and repeatability check

a) Switch off the power supply and stop any water flow.

e) Clean the sample tube accurate by using a suitable cell cleaning brush as

described under Section 12.0. Make sure, that the offset is correct at ± 0.

f) Run clean water through the instrument.

g) If it is sure, that non aerated, clean water is in the instrument, the reading

should be 0 ppm ± 2 ppm.

a) Continue as described under Section 11.0.
