High voltage safety

warningThe voltages used to power this equipment are

potentially lethal. Even 110 volts can kill.

Whenever possible, the following precautionary

measures should be taken before any work is

carried out inside the equipment:

• Switch off all high-voltage power supplies.

• Check the operation of any door interlocks

and any other safety devices.

• Completely discharge all high-voltagecapacitors.

It should be noted that interlocks and safety

devices are normally located only at regular

access points, and high voltages may be exposed

during dismantling.

NEVER WORK ALONE ON

HIGH-VOLTAGE EQUIPMENT!

FIRST AID IN THE EVENT OF

ELECTRIC SHOCK

Normally, even a high voltage electric shock will

not kill instantly. The victim can still be revived

even when his breathing and heart-beat have

ceased.

Could YOU save someone’s life? In the event of

electric shock, the correct actions, performed

quickly may well save the victim’s life. Make

sure you know what to do!

Immediate action

While shouting for help, remove the source of

power from the victim. Switch off the supply if

possible, or using a dry, non-conductive material

(rubber gloves, broom handle etc.) to insulate

yourself, separate the victim from the source. If

the voltage exceeds 1000 volts, switch off the

supply and be ready to catch the victim. Take

care- do not become a victim yourself.

Commence first aid on the spot. Continue to shout

for assistance till someone arrives.

1 Lay the victim flat on his back and loosen

any tight clothing (collar, tie, belt etc.).

2 Open his mouth and check for and remove

any false teeth, chewing gum etc.

3 Check if the victim is breathing. If not,

check if his heart is beating. The pulse is

normally easily found in the main arteries of the

neck, either side of the throat, up under the chin.

If his heart is beating but he is not breathing,

commence ARTIFICIAL RESPIRATION. If the

victim’s heart is not beating, commence

EXTERNAL CARDIAC MASSAGE (ECM).

Continue to shout for assistance till someone

arrives.

EXTERNAL CARDIAC MASSAGE

1 Kneel beside the victim. Place the heel of

one hand in the centre of his chest, at a position

half way between the notch between the

collar-bones at the top of his chest, and the dip in

the breast-bone at the base of his rib cage. Place

the other hand on top of the first.

2 Keeping the arms straight and using your

entire weight, press down rapidly so that the

breast bone is depressed four- five cm, then

release the pressure. Repeat rhythmically at a rate

of one cycle per second. This will be hard work,

but keep going. His life depends on YOU. Do not

worry about breaking his ribs - these will heal if

he survives.


6/317

ARTIFICIAL RESPIRATION

1 Kneel besides the victim’s head. Place one

hand under his neck and lift, allowing his head tofall back. This will lift his tongue and open the air

passage in his throat.

2 Place the palm of the hand on his forehead

to maintain the ”chin-up” position.

3 Using the index finger and thumb of the

same hand, pinch the victim’s nostrils closed.

Open his mouth.

4 Take a deep breath and cover his mouth

with yours. Blow steadily into his lungs to expand

his chest. Remove your mouth from his to allow

the air to escape from his chest. You should be

able to see his chest deflate.

5 Repeat the ”inflation-deflation” cycle at a

rate of about 12 cycles per minute till the victim

begins to breath normally again.

COMBINING EMC AND ARTIFICIAL

RESPIRATION

If you are alone, perform ONE cycle of artificial

respiration for every FIVE cycles of EMC. This

will be hard work, but keep going. His life

depends on YOU!

If there are other people available to help, oneshould perform the EMC while one performs the

artificial respiration for every five cycles of EMC.

It will be much more efficient with two people.

Once the victim’s heart is beating and he is

breathing, roll him onto his side and support him

in that position. As consciousness returns he may

vomit, and this will allow any liquid to drain out

of his mouth.

Remove the victim to a hospital as soon as

possible, but do not interrupt the artificial

respiration and EMC cycles till his heart beat andbreathing returns.

If started quickly and performed correctly, the

resuscitation methods described will keep a

sufficient volume of oxygenated blood flowing

trough the victims body to allow full recovery.

Proficiency in the resuscitation methods can only

be achieved trough training. All personnel

concerned should attend courses on a regular

basis. Remember, someone’s life could depend on

you.

DO YOU KNOW WHAT TO DO?

1.2 Overview

The DataChief

C20 is an Alarm and monitoring system withprocess control and power management. Modular design allows

flexibility in configuring the system to individual requirements,

covering the whole range from low complexity alarm systems to

highly integrated alarm and monitoring systems with advanced

process control. Sub-systems can include all or any combination

of the following:

• Alarm and monitoring system.

• Auxiliary control system.

• Power management system.• Propulsion control.

• Ballast automation system.

• HVAC (air conditioning).

• Management support.

• Reefer monitoring

• Fire system

Note This document describes the DataChief

C20 Alarm and monitoring system with process control and power management.

Thesystem is based on Kongsberg Maritime Ship Systems unified

automation concept, where each individual ship configuration is

built up using standard modules communicating on CAN- and

local area networks. DataChief C20 is configurable for all ship

types, including oil and gas tankers, bulk carriers, passenger

vessels, container and Ro-Ro vessels, reefers and other special

purpose vessels.

The main purpose of the system is to give ship’s officers all thebasic alarms and status information they require in order to

maintain safe and efficient operation of the machinery and other

relevant equipment.

DataChief C20 complies with the requirements of IMO, local

maritime authorities, IACS, and eleven classification societies. It

is designed to meet the classification societies requirements for

periodically unmanned engine room operation. The system

conforms to all rules and regulations, and all modules are type

approved. Thesystem incorporates the latest advances in hardware

and software technology. DataChief C20 is developed to strict

military QA standards.

1.3 Design principles

1.3.1 General

Alarm groups

All alarms and monitored values are divided into alarm groups.

Any alarm can only be part of one group. Each alarm group has a

dedicated button on the operator control panel. If only standard

personalcomputer keyboard is provided theoperator control panel

is displayed on the colour graphics display and works in the same

wayasthephysical panel.Activealarmsare indicatedbya flashing

light (unacknowledged alarm) or steady light (acknowledged

alarm).

Alarm types

Alarm detection for analogue signals

The following functions are included:

• Instrument failure alarms.

• Low-low process alarms with or without action (slow-down).

• Low process alarms.

• High process alarms.

• High-high process alarms with or without action (slow-down).

• Return to normal detection with dead-band to avoid alarmfluctuations.

• Adjustable filter factors to filter fluctuations in the incomingsignals.

• Time delay of alarm triggering and return to normal messages.

Alarm detection for on/off (two state) signals

The following functions are included:• High process alarms (open or closed).

• Return to normal detection.


Alarm detection for on/off signals with line check

The following functions are included:

• High process alarms (open or closed).

• Line broken alarm.

• Line short alarm.

• Return to normal detection.


Inhibit alarm

Some alarmsareconditional andwill be inhibitedwhen a specified

condition is present. This function is accomplished by defining a

signalasan inhibit source fora specifiedalarm or a specifiedgroup

of alarms. An adjustable time delay is available to extend the

inhibit situation for each signal.

1.3.2 Building blocks

The DataChief C20 is a modular system that allows us to meet

individual ship owners requirements using standard modules. The

main building blocks of the DataChief C20 are:

• Distributed Processing Units: Their main functions are to

monitor analogue or digital sensors and toprovide analogueanddigital output to different devices. A number of different

Distributed Processing Units are available to meet specific

control and monitoring applications.

• Remote Operator Stations: Their main functions are toreceive alarms and to allow monitoring and control of the

system. They can display mimic diagrams, allow control of the

Watch Calling System and printing of various logs. They also

enable the operator access to Distributed Processing Units for

inspection of variables, local operation of equipment

adjustment of parameters etc.

• Local Operator Stations: Their main functions are to enablethe operator local access to Distributed Processing Units for

inspection of variables, local operation of equipment

adjustment of parameters etc.

• Watch Bridge Units: Their main functions are to indicateengine room alarms on the bridge while in bridge control and

to accept the transfer of machine watch responsibility to and

from the bridge.

• Watch Cabin Units: Their main functions are to indicateengine room alarms in the engineer on duty’s cabin and in the

public quarters while in bridge control.

6 AD-0377 / Rev C 13.02.2003

• Dual redundant Local Area Network: Used forcommunication between the Remote Operator Stations and

other PC based equipment. Each unit is connected to twocompletely separate Local Area Networks (LAN) for

maximum redundancy.

• Dual redundant CAN-bus: Used for communicationbetweenthe Distributed Processing Units. Each unit is connected to two

completely separate CAN-buses (CAN - Control Area

Network) for maximum redundancy.

• Dual Process Segment Controller: The dPSC is a dual twochannel CAN gateway. In most cases the two channels are

working in parallel on redundant CAN lines. The main

functions are to process messages from the a local CAN-bussegment and send them on the global process bus, where they

are available for other dPSC’s and System Gateways.

• Process Segment Starcoupler: Used to segment the CAN-busso that a short circuit or broken line in one segment will not

affect the functions in the other segments.

• System Gateway: Connects two CAN lines to two Local AreaNetwork lines. The main purpose is to receive messages from

the two process buses running CAN, and update the Remote

Operator Station database.

Different selections of these units are used to configure each

individual system. DataChief C20 is a fully

microprocessor-based system. It is decentralised for safety and

ease of installation but operation is centralised using Remote

Operator Stations (ROS). Each or a group of Distributed

Processing Units can be connected to a Local Operator Station

(LOS) containing display and keyboard for back-up/local

operation.

1.3.3 Decentralised system architecture

The heart of the system isa small family of different intelligent I/O

units called Distributed Processing Units. These communicate

with each other on a redundant high capacity process-bus. All

monitoring and automation functions are carried out by the

Distributed Processing Units, while the centralised Remote

Operator Stations provide the Human Machine Interface.

Each Distributed Processing Unit type has a specific capacity in

number and type of analogue or digital input and output channels.

The number of channels varies from 8 to 32.


25/317


26/317


8 AD-0377 / Rev C 13.02.2003

The Distributed Processing Units have been designed for

immunity againstsingle failures. EachDistributedProcessing Unit

has an internal three way galvanic isolation between power,communication and input/output channels. If a unit fails this will

not affect the power source, communication bus or damage the

sensors. The Built InSystem Test will detect the error and warn the

operator. Failures to the process-bus, cabling or connected sensors

will also be detected by the Built In System Test.

Exchange of a faulty Distributed Processing Unit can be done

without turning the power off the DataChief C20. The procedure

is simply to disconnect and remove the faulty unit and then mount

and connect a replacement. The operator then requests the system

to replace the module, software is automatically downloaded andthe Distributed Processing Unit starts operating.

All Distributed Processing Unit types have been qualified

according to the latest revision of the IACS E10 test procedure,

satisfying the requirements for placement in the most demanding

locations. All Distributed Processing Units can be mounted

directly on diesel engines or similar locations without shock

absorbers. Only Ingress Protection (IP) may be needed. The

Distributed Processing Units are CE marked as required for some

European Union flagstate vessels. They also meet the

requirements to use the “Wheel Mark” defined by the EuropeanUnion Maritime Directive (EMD), satisfying all the new

Electromagnetic Compatibility (EMC) requirements.

1.3.4 Centralised operation

DataChief C20 is operated througha numberof RemoteOperator

Stations. These are normally located in the Engine Control Room.

Additional stations may be located in the wheelhouse, cargo

control room, damage control room, ship’s office or other parts of

the vessel. The Remote Operator Stations are normally connected

to the Distributed Processing Units trough a Dual RedundantControl Area Network.

The Remote Operator Stations are fitted with colour graphic

displays and are operated either using a standard PC keyboard and

mouse or through a purpose built Operator Control Panel.

The Remote Operator Stations provides the operator with a

number of standard display pictures containing information about

the engine and surrounding equipment. Control of any of the

Distributed Processing Units can be performed from the Remote

Operator Stations. Full monitoring and alarm facilities are

provided in both machinery space and Engine Control Room.


27/317


9AD-0377 / Rev C 13.02.2003

Advanced facilities can also be provided for unmannedmachinery

space, and the watch-calling system allows automatic calling of

duty engineers. This allows both machinery space and enginecontrol room to be safely left unmanned, while the machinery

watch is carried out from the bridge.

All Remote Operator Stations are Windows based personal

computers; type approved for maritime use. They work in parallel;

none of them acts as master. All are interconnected via dual

redundant local area network. Although every Remote Operator

Station is identical, access to vital functions may be configured

differently. The control availability is defined by extensive use of

software password access. Some Remote Operator Stations such

as units located in the ship officeare normally used for monitoringonly. These units will not allow acknowledgement of alarms or

execution of control commands. All general information such as

monitoring of alarms, trends and graphics are available for

inspection.

Changing a limit or parameter on one Remote Operator Station

will automatically update all other stations. All operator actions

such as the starting or stopping of a pump or the changing of an

alarm limit are logged and time tagged (optional).

When ever a variable or state changes significantly the Distributed

Processing Units updates the database in each of the Remote

Operator Stations. This means that data displayed at any Remote

Operator Station is always up-to-date. There is no need to request

data each time the operator wishes to inspect a variable. As a result

of this, the data traffic on the process bus and the Local Area

Network is kept to a minimum, giving extremely fast data access.

The Remote Operator Station serves as the database host for

process data, engineering data and software. Software for Remote

Operator Stations and the different Distributed Processing Units

are stored here. They include functions for automatic down

loading of parameters to the Distributed Processing Units at

commissioning time or when a Distributed Processing Unit is

replaced.

Configuration control of DataChief C20 systems is taken care of

by an automatic version update at any change of the engineering

database or the application software. The system logs all changes

made. Versionnumbers and additional informationcanat anytime

be individually inspected for each DataChief C20, as required by

the major classification societies. Our commissioning editor

“Tools” is used to configure or modify the functionality of the

DataChief C20 and is used to generate ”as built documentation”.

1.4.1 Remote Operator Station

Figure 5 Remote Operator Station (ROS)

The Remote Operator Station is a type approved personal

computer, connected to a colour graphics display and a printer.

Operator input is either done through a standard personalcomputer

keyboard or through our custom made Operator Control Panel.

The Operator Control Panel is a specially designed keyboard that

provides easy access to the different operator functions. It is

divided into separate function areas. Buttons are combined with

lamps to indicate alarms, status of the ExtendedAlarm Systemand

to indicate main system functions. The Operator Control Panel is

in many cases connected to an external ”sound off” button.

The Remote Operator Station can be supplied with a printer (for

on demand printing), an alarm printer, log printer or colour hard

copy unit. When a Distributed Process Unit detects an alarm

condition, the alarm is identified by a flashing indicator on the

Operator Control Panel. The alarm is also displayed on the colour

graphics display, a buzzer is turned on and the Alarm Printer

automatically prints the alarm. By pressing the button associated

with the flashing indicator more detailed alarm information is

displayed on the colour graphics display.


31/317


13AD-0377 / Rev C 13.02.2003

Detailed sensor informationfor anyDistributed Process Unit, such

as alarm or normal status data, can also be shown on the colour

graphics display, or printed on demand. Analogue sensor data canbe presented as a bargraph or a trend curve. Selected sensor data

may be printed automatically at fixed intervals. The system can

display the latest alarms for each alarm group individually or all

active alarms.

The logging printer and the colour graphics display records all

status changes, such as alarm acknowledgements and alarm

condition cleared. When all alarm conditions are cleared, the

system returns to normal.

Alarm limits and delays are adjustable from the Operator Control

Panel.A counter function keeps track of running hours forengines,pumps and related items. This function can also accumulate flow.

Counter values are shown on the colour graphics display or may

be printed.

TheRemoteOperator Station is used when transferringmachinery

watch responsibility between bridge and engine control room.

Selecting the engineer for watch-call duty is carriedout fromhere,

and all available engineers, whether on duty or not, may be called

to the engine control room in the case of an emergency.

1.4.2 Midi operator station

Figure 6 Midi Operator Station (MOS).

The Midi Operator Station is a multipurpose operator station

designed to be placed anywhere on the ship, even out on deck. It

allows alarm indication, process control and power management.

Operation is performed through a set of function keys and a high

resolution colour graphical display. For small alarmsystems it can

be the only operator station. The Midi Operator Station contains

a symbol library for presentationof processcontrol equipment anduse these to display mimic diagrams. The Midi Operator Station

gives the operator the possibility to:

• Monitor the status of any object, from a single input signal toa controllable object.

• Be informed of any process- or system alarm, through visualand audible signals.

• Interface to a printer for alarm loging purposes.

• Control the process through built-in pushbuttons and graphical

feedback.• Reconfigure the distributed database located in the Distributed

Processing Units, through numeric and alphanumeric inputs.


33/317


15AD-0377 / Rev C 13.02.2003

1.4.3 Local operator station

Figure 7 Local Operator Station (LOS).

The Local Operator Station is an optional operator control panel.

It includes a four line by 40 characters Liquid Crystal Display

(LCD display) andpush-buttonsforoperator interaction. It is used

to allow local access to the Distributed Processing Units for

inspection of process variables, local operation of equipment,

simulation of input/output signals, adjustment of parameters andinspection of the built-in diagnostics.

All Distributed ProcessingUnits connected to the same CAN-bus

astheLocalOperatorStationareaccessible.Assoonasconnection

is established, the Local Operator Station is able to control the

selected DistributedProcessingUnit.Thedialoguesaredefinedby

the functionalityof each individual typeofDistributedProcessing

Unit.

If a Distributed Processing Unit is isolated from the rest of the

system because of a communication break-down, or because the

Remote Operator Station has developed a serious fault, all thenecessary alarm and monitoring functions can as an option be

available locally. Detailedinformation on thetype ofalarm and its

source is then available at the Local Operator Station.

16 AD-0377 / Rev C 13.02.2003

1.4.4 Watch Bridge Unit

Figure 8 Watch Bridge Unit (WBU), LCD type.

Two different types of Watch Bridge Units exist, an LED and a

LCD type. Both are used to indicate and accept the transfer of

machine watch responsibility between bridge and engine control

room. The LED type has more alarm indicators and the LCD type

has a display to show alarms in clear text.

Figure 9 Watch Bridge Unit (WBU), LED type.


35/317


17AD-0377 / Rev C 13.02.2003

When the bridge has the machinery watch responsibility, one or

more engineers must be on call. A general alarm signal will call

them to the engine control room if an alarm condition arises. Thealarm indication on the Watch Bridge Unit is that a buzzer sounds

and a single or group alarm lamp is flashing. When an alarm is

acknowledged in the engine control room, or the situation is

cleared, appropriate indications are given on the Watch Bridge

Unit.

The DataChief C20 prevents the bridge from assuming watch

responsibility if no engineers are assigned to on call duty. The

bridge personnel may call the engineers on-duty in their quarters

at any time, for consultation etc. Acknowledgement of such calls

are provided.

Alarm indication can beprovidedwhen the bridge isnot havingthe

machinery watch. Indicators show when an alarm has been

acknowledged in the engine control room but the buzzer is not

sounded.

1.4.5 Watch Cabin Unit

Figure 10 Watch Cabin Unit (WBU), LCD type.

Two different types of Watch Cabin Units exist, an LED and a

LCD version. Both are used to indicate engine room alarms. They

are placed in the engineers cabins and in public areas. The LED

type has more alarm indicators and the LCD type has a display to

show alarms in clear text.

To set the machinery watch responsibility system to bridge mode

one or more engineers must be on call. When an alarm condition

arise a general alarm signal is sounded in the duty engineers cabins

and in the public areas. The visual alarm indication on the Watch

Cabin Unit consists of single or group alarm lamps.


36/317


18 AD-0377 / Rev C 13.02.2003

Figure 11 Watch Cabin Unit (WCU), LED type.

When the bridge has the machinery watch responsibility, one or

more engineers must be on call. When an alarm situation occur the

alarm signal will be given, both in the duty-engineers cabin and in

the public areas. The visual alarm indication on the Watch Cabin

Units are that a buzzer sounds and a single or group alarm lamp is

flashing. The engineer will then normally go to the engine control

room to find the cause of the alarm. When the alarm is

acknowledged in the engine control room, or the situation is

cleared, thealarm condition is cleared from theWatch CabinUnits.

If the engineer does not acknowledge within a specified period of

time, the alarm signal is repeated in the engineers’ quarters, and on

the bridge, until it is acknowledged. The system can also be used

to call an engineer to the bridge or the enginecontrol roomwithout

an alarm condition. Alarm indication without sounding the buzzer

is configurable when the Watch Calling System is in off-duty

mode.

1.4.7 Distributed Processing Units

GeneralA number of different Distributed Processing Units are available

for different tasks. The main functions of the Distributed

Processing Units are to monitor analogue or digital sensors and to

provide analogue and digital output to different devices. All units

have the same mechanical construction and are built using the

same electronic design principles. The main characteristics of the

Distributed Processing Units are:

Figure 12 Distributed Processing Units (DPU)

• Each unit is remotely configurable.

• No serviceable parts inside.

• All connections are plugable.

Each Distributed Process Unit contains its own microprocessor.

These are programmed for a number of different tasks such as

detecting when a monitored signal move outside set limits.

Unwanted alarms are inhibited during start-up and shut-down of

the machinery. Status information is continuously monitored by

the DataChief C20’s Remote Operator Stations through thesystem network.

When an unacceptable condition is detected, the Distributed

Process Unit and DataChief C20 generates an alarm signal,

identifies the responsible sensor, and provides information about

the condition. The following gives a short description of each

Distributed Processing Unit type:

CAN net status, error handling.

Process Segment Starcoupler

The CAN line is vulnerable against short circuit and unterminated

lines. A short-circuit or a broken line will disable the entire CAN

segment. The Process Segment Starcoupler protects two sections

of a CAN segment from each other.

Each terminal on the Process Segment Starcoupler is based on the

ISO 11898 standard, with optical isolation. The Process Segment

Starcoupler also protects the terminals against dominant bits that

are not part of a CAN message. Thus short-circuit or malfunction

on one CAN terminal does not affect the other CAN terminals.

The maximum length of one CAN segment at 125kBaud is 530m.

A segment going through a Process Star Coupler is limited to

515m. This length is the maximum line length between any two

nodes in the CAN segment. For that reason it is advised to use the

Process Segment Starcoupler to split two sections of a processsegment, where the segment is running through rough

environment or fire zones.

Voltage converter controller (VCC)

The VCC-440 module is designed for use in main switchboards.

The module secures the installation of the power management and

generator protection system, by transforming the higher voltages

to low and safe levels. The VCC-440 module is equipped with six

voltage transformers to transform from 440 to 24 VAC. The

module handles three major tasks:• Supply the C3 generator protection module with AC voltage

from the measured three phase generator bus bars, L1-L2,

L1-L3 and L2-L3, derated from 440 to 24 VAC.

• Supply theC3 generator protectionmodulewith 24VDCpower(1A), using the generator busbar (L2-L3) as source.

• Supply the C4 power management module with a single phaseAC voltage from the generator busbar L1-L2 and the

switchboard busbar L1-L2, derated from 440 to 24 VAC.

As an option, the VCC module can be equipped with transformers

for 690 VAC.

• The System Gateway: Used as a redundant gateway betweenCAN-bus and Local Area Network.

• The dual Processing System Controller: Used as a redundantgateway between two CAN segments (sections of the

CAN-bus).

The main purposes of both units are to provide galvanic isolation

betweendifferentpartsof thenetwork and to segregateprocess bus

traffic in large systems. Messages are then converted between the

network parts, while maintaining redundancy.

Both units provide a service to protect all nodes (Distributed

Processing Units, Watch Bridge Unit, Watch Cabin Units and

Local Operator panels) connected to the CAN-bus. If thecommunication with one node fails, the gateways will generate a

system failure message identifying the node and the failure. The

Dual Process System Controller may also be equipped with

supervisory control logic for particularly demanding tasks.

The System Gateway – SGW

The System Gateway is a four channel CAN-bus to dual Local

Area Network gateway. Its main task is to receive messages from

the two CAN-buses, and update the Remote Operator Stations.

Handling of operator commands and downloading of parameters

and software from the Remote Operator Stations to the nodes

(Distributed Processing Units and Local Operator Stations) are

handled as well.

The System Gateway will route global CAN-bus messages

between the four CAN-buses. Global messages are data messages

needed in more than one bus segment, typically messages for

inhibiting or blocking alarms during start-up or shut-down.
