contact details. The symbols below will accompany for a better understanding.

Disposal

The crossed-out waste container icon on waste electrical or electronic device indicates

that this device must not be disposed of with household waste at the end of its life. There

are collection points available in your area for free. The addresses can be obtained from

your municipality or local administration. You can also email us at [email protected] to

find out further return options provided by our company.

Separate collection of waste electrical and electronic equipment (WEEE) is intended to

prevent the re-use, recycling other forms of use of WEEE as well as to avoid adverse

effects on the environment and human health from the disposal of potentially hazardous

substances contained in devices.

IMPORTANT NOTICE

Replacement components for 15 ppm Bilge Alarms

General

All monitors in our range are inspected and tested to the related International Maritime

Organization IMO 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

manual.

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 IMO resolution MEPC.107(49).

Remark

According the MEPC.107(49) § 4.2.11 the units have 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-2008 Series are designed in that way, that only the Measuring Cell needs to be changed,

as these units carry the Calibration Certificate. 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 months. The new Computer Unit will carry its own

memory card. The old card can be inserted into the new unit only for reading. Writing is only

possible with the card delivered with the new Computer Unit. For details see section

15. Memory Card.

Warranty

Our warranty terms are 12 months after installation but maximum 18 months after delivery ex

works. The maker undertakes to remedy any defect resulting from faulty materials of

workmanship except wearing parts.

The maker's obligation is limited to the repairs or replacement of such defective parts by his own

plant or one of his authorized service stations.

The purchaser shall bear the cost and risk of transport of defective parts and repaired parts

supplied in replacement of such defective parts.

ANY DISMANTLING OR BREAKING OF A SEAL WILL VOID THE WARRANTY.

1. Introduction

The OMD-2008 Series Bilge Alarm Units have been designed specifically for use in

conjunction with 15 ppm oil-water separator units and have a specification and

performance which exceeds the requirements of the International Maritime Organization

IMO specifications for 15 ppm Bilge Alarms contained in Resolution MEPC.107 (49).

The units are supplied with 2 works-adjusted alarms at 15 ppm. Set points from 1 ppm to

15 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 exceeded, the alarms are visible at the front panel and the

appropriate relays are switched. In case of malfunction the “SYS LED” at the front panel

will change from blinking green to permanent red.

For the data logging function, the unit requires a status input from the separator.

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

external meter.

By request the OMD-2008 Series are also available with 5 ppm alarm set point.

Additionally, instrument versions equipped with a Measuring Cell Cleaning Unit or an

Automatic Cell Cleaning Device are available.

OMD-2008 Series generally consist of a Computer Unit, a Measuring Cell, and further

equipment (e.g. Valve Assembly, EV Valve, Automatic Cell Cleaning Device, and EV Flow

Control).

The Computer Units contain the display PCB with the data logger and the terminals for

external connections.

The Measuring Cell is built out of an anodized all-aluminium body with inlet and outlet

block made from stainless steel. This rugged cell contains optics and electronics and is

connected with the Computer Unit via a plugged data cable.

The Measuring Cell should be positioned vertical.

All OMD-2008 units are mounted onto stainless supports and can be mounted on wall or

as bulkhead installation.

The OMD-2008 Series 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, which is less than 5 sec.) 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-2008 Series instrument by means of M6 or M8 screws on to a rigid

vertical surface or frame and preferably with the display panel of the monitor at user

convenience. 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.

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.

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.

Electrical connections are made through the metric cable gland openings prepared

underneath the instrument. Not all openings may be free. The electrical connections are

located inside the computer housing.

The Units 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.

Close front cover completely after electrical installation. Water and humidity inside the

instrument may result in corrosion and malfunction.

If the instrument is operated at high voltages, additional care has to be taken to provide

reliable ground connections. Ground (PE) must be connected direct to the PE terminal or,

if this is not sufficient according local rules, to the computer housing (PE bolt inside, right

side).
