1 INTRODUCTION This manual is generated through the configuration tool called Seamate. The manual is therefore customised for each system delivery.

The intention with this manual is to explain the functionality for each mayor component and the total system as it’s configured for each delivery.

How to operate the system is described in a manner where we assume that the system is in operation and that normal operations shall be carried out. This manual is not made for advanced troubleshooting.

The manual contains five chapters

2 FUNCTIONAL DESCRIPTION

2.1 Remote Control System Functional Description

The Kongsberg Maritime C20 Marine Automation system consists of, among others the AutoChief® C20 Propulsion Control System. Modular design allows flexibility in configuring the system to individual requirements, covering the whole range from standard propulsion configurations to highly advanced twin or quadruple engine installations with high, medium or low speed engines connected to reduction, reversing gear or variable pitch propellers. This system may be a part of a total integrated ship control system consisting of other sub. Systems such as: • Alarm and monitoring system. • Auxiliary control system. • Power management system. • Ballast automation system. • HVAC (air conditioning). • Management support

The system is based on Kongsberg Maritime unified automation concept, where each individual ship configuration is built up using standard modules communicating on CAN- and local area networks. The C20 system is configurable for all ship types. The AutoChief® C20 Propulsion Control System is designed for remote control of the main engine from the combined telegraph and manoeuvring lever in the wheelhouse. By moving this lever, the system will automatically start, reverse, stop and speed-set the main engine.

2.10 Remote control system functions

2.10.1 Start block

As long as any of the below mentioned conditions is active the engine is inhibited for starting.

2.10.1.1 Engine tripped

Engine has tripped because of a shut down detected and created by the safety system.

Details to be found in the alarm list on the Safety system mimic pages.

2.10.1.2 Start air pressure low

To secure a safe starting of the main engine a minimum starting air pressure is required. The value for minimum starting air pressure allowed is preset in parameters in the remote control system. If the pressure is below this preset level Start Block is activated.

2.10.1.3 RPM detector failure

RPM monitoring is critical for starting and running of the engine, So if the RPM measuring system is experiencing a redundant detector failure the engine is inhibited for starting.

2.10.1.4 Governor not connected

When the engine is operated from the local control stand and fuel control is carried out manually the Electric fuel actuator has to be de-clutched from the fuel linkage system. If the Actuator is not engaged to the fuel linkage, starting is inhibited.

2.10.1.5 Start air valve blocked

For safety reasons, when the main engine is not in use, the main start air valve is mechanically blocked. To be able to start the engine the main start air valve has to be set to service position.

2.10.1.6 Start air distributor blocked

For safety reasons, when the main engine is not in use, the start air distributor is blocked. To be able to start the engine the start air distributor has to be set to service position.


36 AA-0381-A

2.10.1.7 Turning gear engaged

The turning gear is mechanically engaged to the flywheel. The main engine is therefore inhibited from starting.

2.10.2 Starting the main engine

If the engine is prepared for start the engine is started automatically in ahead (or astern) direction from simply by setting the bridge handle from stop to any position in ahead (or astern) direction

2.10.2.1 Slow turning

If the engine has been stopped for a certain time (normally 30 minutes), the first start will include one revolution with slow turning of the main engine. When a start order is given from bridge (by setting the bridge lever from stop to any position ahead (or astern)) the slow turning valve will be activated, and a limited amount of starting air will be supplied to the main engine, the engine will rotate slowly on starting air.

When one revolution is completed, the engine will be started in a normal way. During the slow turning sequence slow turning indication will be shown in the control room and bridge ACP. If one revolution with slow turning is not accomplished within the correct time, alarm "slow turning failure" is released in control room and bridge. Slow turning may be cancelled by operating the "cancel limitation" pushbutton on the ECR and bridge unit. Note ! Some engines may not be equipped by slow turning

valve.

2.10.2.2 Normal start

Starting of the main engine is performed when the bridge lever is moved from stop to any position in ahead (or astern direction). The system will activate the starting air solenoid valve, and starting air is supplied to the engine. System will at the same time give a fixed starting-speed set-point to the governor.


AA-0381-A 37

When the engine speed has reached the start-air / fuel change over level, starting air will be switched off, and fuel will be supplied. The starting-speed set-point will be kept for 6 seconds (adjustable), and then the speed set-point to the governor will be adjusted in accordance with the set-point of the bridge lever.

2.10.2.3 Restarting

If the engine fails to start (run on fuel) after the starting air is switched off, the system will automatically try to restart the engine. Indication for "repeated starts" will show on bridge and ECR. The starting speed set-point to the governor will at the second (and third) starting attempt be higher (heavy start), and the fuel limiters for scavenge air and torque in the governor will be cancelled. If the second start also fails, the system will try a third start. After 3 failed starting attempts, start fail alarm will be released.

2.10.2.4 Starting failure

Starting failure is detected when one of the following conditions occurs, and is indicated on ECR and Bridge ACP. 3 failed starts Start too long Slow turning failure "Start too long" means engine is unable to reach the start-air/fuel-change level within a specific time period.

Start failures are reset by setting the manoeuvring lever to stop

2.10.2.5 Heavy start

Heavy start is a automatic function activated in two segments of the propulsion control system. Firstly in the remote control system as a heavy start RPM set-point, thereafter as a higher pump index set-point to the fuel actuator. The Heavy start function is automatically activated if the crash astern function is activated.


38 AA-0381-A

2.10.3 RPM limiters

For protecting the engine and its accesories against thermal stress and destruction and unnecessary wear and tear some fixed RPM Limiters are included in the system.

2.10.3.1 Manual RPM

This function is also called Chief RPM Limit. It’s a parameter in the remote control system, initiated by the ACP for pre-setting maximum allowed RPM for ahead or astern running. If the RPM command is set higher, the command will be limited to the value inserted in this parameter.

2.10.3.2 Load program

When setting the bridge handle to Navigation Full position, load program will be activated. This will be indicated as "load up program active" on the ACP. The purpose of this function is to prevent engine internal temperatures i.e liners and pistons, from increasing too fast when higher load is applied. When MCR is obtained (in 30 minutes) the “load up program active” indication will disappear. The same function may also apply for the opposite purpose. When reducing speed from Navigation Full to full ahead the load down function is activated, slowly decreasing the speed to allow the engine to cool down (normally 15 minutes).

2.10.3.6 Barred speed range/Critical RPM limiter

Critical RPM avoidance In order to avoid operation of the main engine in critical (barred) speed areas, there is provided a command limiter function. If bridge command is within this area, the "critical RPM limit" on bridge and in control room ACP will turn up. The system will during acceleration keep the engine running at the lower critical speed until command has reached the upper limit, during de-acceleration it will keep the engine running at the upper limit until command has reached the lower limit. There is possibility for two different critical RPM avoidance areas. Critical RPM alarm If the engine RPM run within the critical (or barred) speed range too long time, indication for "critical RPM" will be shown on the ACP. There are two critical RPM zones available.

2.10.3.7 Shaft Generator control mode

When shaft generator (PTO) is provided with a constant frequency gear (CFR), an optional function in the remote control system is available in order to avoid black out during speed reduction and slow down. An input signal from the generator breaker in the main switchboard "shaft generator connected" should be connected to the remote control system. The remote control system will give the signal "start diesel generator & disconnect shaft generator". When shaft generator is connected to the switchboard, the engine speed should be above a certain level (normally 75% of MCR, adjustable). If speed command is ordered below the lowest working level for shaft generator, from the bridge handle, or because of slow down, the following sequence take place:

• The speed will rapidly be decreased to shaft generator minimum working level.

• "RPM holding" indication in bridge and control room ACP

• Signal "start diesel generator starting & disconnect shaft generator" will be given to the main switchboard.

• Speed will be kept at the shaft generator minimum working level until signal "shaft generator connected" goes off, or maximum 60 seconds (adjustable).

• After the signal "shaft generator in service" extinguish, the speed will be reduced to the required level (bridge handle requirements or slow down level).

• The same sequence applies when STOP or CRASH MANOEUVRING order are given.

For shut down and emergency stop, the system will immediately stop the engine, resulting in a black-out.

2.10.4 Operation modes

2.10.4.1 Rough sea mode (option)

The rough sea mode is optionally provided in order to avoid over-speed trip during rough sea conditions. Selecting rough-sea mode is to be done from the ACP menu. When rough sea mode is selected, and over-speed is detected, the following sequence will take place. • When the engine speed reaches the over-speed level, the

fuel will be cut-off, the engine speed will decrease. • When the engine speed reaches shut down reset level, fuel

will be supplied, and the engine will be running at this level.

• To reset, move speed-set lever back to reset level and move handle to desired RPM.

There is an upper speed limit for this function (adjustable). The upper limit is provided to avoid fluctuation between over-speed, and stop. MAN B&W does not approve this function, however it is provided as an option.

2.10.8 Load Change Dependant Cylinder Lubrication Function

This function allows for additional cylinder lubrication. The condition to give extra cylinder lubrication is when a distinct and permanent load change is detected.

2.10.9 CCO, Cylinder cut out function

This function’s main purpose is to improve the stability of rpm when the engine is operated at low load and rpm. The system is cutting the operation of cylinders in groups, normally 2. Meaning that during this operation only half of the cylinders will be in operation simultaneously. The operation of the cylinder groups (Group1 and 2) is alternating on a time basis. The reason is to avoid excessive amounts of cylinder lubricating oil as the surplus oil is burned. Another reason is for keeping the same thermal load on all cylinders.

In order to obtain a safe start the cut out system is disabled during the starting period and until the engine is running stable.

If cancel limiters is activated or if the RPM command from the telegraph lever differ from the measured RPM within pre-defined limits the cut out system is disabled and all cylinders will be active.

2.11 Safety system functions

2.11.1 Safety function Shut down

2.11.1.1 Shut Down Function (1 – 6)

Then engine will automatically shut down (stop), if any of the shut down sensors is activated. The emergency stop solenoid valve will be activated, and the fuel rack to zero order is given to the governor. The engine will then stop. The following inputs for shut down sensors are provided: Shut down 1: (Fixed as over speed) Shut down 2-6: (To be project specified for the actual

project) Custom Shut down 1-5 (To be project specified for the actual

project) The input sensors may be of digital (on/off) or analogue type. The shut downs may be configured as cancellable or non cancellable type. Non cancellable types will stop the engine immediately. Shut down is reset (after the sensor is de-activated) by setting the manoeuvring lever at the control stand in control to stop position. The engine may then be restarted.

2.11.1.2 Cancellable Shut Down

It will be possible, during the pre-warning time, to cancel the shut down by pressing the “Cancel SHD” pushbutton on the ACP unit. There will be time delay on the cancellable shut downs. The delay time may be adjusted individually for each sensor. The cancellable shut-downs may be cancelled individually from the ACP in control room, regardless of control position, it will additionally be possible to cancel all shut-downs from bridge while in bridge control, control room in control room control and from engine side while in emergency control. The indications mentioned will be shown on the LCD display of the ACP unit.


48 AA-0381-A

2.11.1.3 Emergency Stop function

Safety System has possibility for total 5 emergency stop push buttons Normally 3 emergency stop pushbuttons will be used:

Bridge Pushbutton with light with integrated in bridge LTU.

Control Room Pushbutton with light with cover integrated in the ECR LTU

Local Control Pushbutton with light with cover integrated in emergency control PBT.

Bridge Wing (Option)

Pushbutton with light and cover integrated in the BWU

The emergency stop solenoid valve is directly activated through the ESU when one of the pushbuttons is activated. Stop signal is sent to the RCS and zero fuel order is given to the governor. The engine will stop, and an alarm "emergency stop" is activated", Information of which of the emergency stop pushbuttons that are activated will be shown on the ACP. Emergency stop may be activated from all control stands at any time, regardless of the control position. Emergency stop is simply deactivated when the pushbutton is pressed once more.

2.11.1.4 Over-speed Shut Down

Over speed is detected by the RPM detection system, from tacho pick-ups which are mounted towards the engine fly-wheel, when the engine revolution exceeds the over speed level (109% of MCR, adjustable). A hardwired signal from the RPM detection system is connected to a shut down input on the ESU for direct activation of emergency stop solenoid valve. And the RPM detection system will by dual redundant CAN order shut down of engine to RCS, Safety System and Governor System. This will cause the emergency stop solenoid valve to be activated and the fuel rack position moved to zero. The engine will stop and the alarm "over speed" will be shown on the ACP. Over speed is reset by setting the manoeuvring lever at the control stand to stop position. The engine may then be restarted.


AA-0381-A 49

2.11.2 Safety function Slow Down

2.11.2.1 Slow Down Function (1 – 20)

The engine will automatically reduce the speed corresponding to slow (adjustable) if any of the slow down sensors is activated. Slow down signal will be sent to the remote control system and/or the governor, which takes action. Slow down is indicated on the ACP. The inputs for slow down sensors are as follows: Slow down 1-20: (To be project specified for the actual

project) The input sensors may be of digital (on/off) or analogue type. The slow downs may be configured as cancellable or non cancellable type. Non cancellable types will reduce the engine speed immediately; while there will be time delay on the cancellable ones. The delay time may be adjusted individually for each sensor. The cancellable slow-downs may be cancelled individually from the ACP in control room, regardless of control position, it will additionally be possible to cancel all slow-downs from bridge while in bridge control, control room in control room control and from engine side while in emergency control. Slow down is either automatically reset after the sensor is de-activated, or alternatively, it is reset when the sensor is de-activated, and the bridge handle is set below the slow down level. A none cancellable slowdown will activate speed reduction immediately after the time delay has run out. Slow down action is performed as follows:

Bridge Control Automatically by the remote control system.

Control Room Contr. Automatically by the governor or manually by the operator

Local Control: Manually by the local fuel control device.


50 AA-0381-A

2.11.2.2 Cancellable Slow Down

It will be possible during the time delay to cancel the slowdown by pressing the "Cancel SLD" pushbutton on the ACP unit. If not cancelled, the slow down will be activated and be indicated as "slow down activated" and the speed set-point will be reduced to the slow down level, normally corresponding to dead slow (adjustable). It will be possible to adjust main engine speed in the area between minimum run and slow down level. Slow down is reset automatically, when the slow down signal goes off. The indications mentioned will be shown on the LCD display of the ACP unit.

2.11.3 RPM detection The AutoChief®C20 is furnished with two independent RPM measurement systems. These systems will at all time ensure correct reading of the RPM pickups and give alarm in case of irregularities.

The governor uses an electric motor connected to a gear as actuator and an electronic regulator. The main functionality of the Digital Governor is: Regulator functions: • Controlling speed of the main engine based on set-point from

lever in control. • Protecting the engine from overload. • Constant fuel mode (Increases the dead band for speed

regulation) • Load dependent cylinder lubrication Actuator functions. • Setting the fuel rack in the correct position based on the order

from the governor unit • In case of major failure, to block fuel in order to maintain

speed and thrust


52 AA-0381-A

Governor management In bridge control, the governor is managed by the remote control system. In control room control, the governor is managed either by the AutoChief®C20 ECR manoeuvre handle or the separate control room manoeuvring handle.

2.12.1 Constant fuel mode

This function is used when the governor system is made by Kongsberg Maritime a.s.

The RPM is continuously measured and when the RPM has remained constant for a predefined time the governor system will be informed that the constant fuel mode shall be engaged. The governor will then lock the fuel actuator output to a fixed fuel index. When the Fuel index is locked the RPM will fluctuate. This function is required in some cases i.e. when indicator diagrams shall be made and similar. During this sequence the RPM is continuously monitored and compared with an upper and lower RPM deviation parameter. If the RPM fluctuates above or below these limits, the fuel actuator output will be unlocked and the RPM is governed back to the set-point requested from the remote control system.

It is also limiters for which rpm areas this function may be used. I.e. it’s not allowed in low rpm areas where the engine may stop if the fuel amount is not controlled continuously or, in high rpm areas where the engine may increase to over speed rpm level.

2.12.5 Fuel start set-point

When start is activated from the remote control system the governor will preset the fuel pumps to a fixed pump index. The fuel start set-point is deactivated as soon as the engine passes the start set-point rpm level.


54 AA-0381-A

2.12.6 External stop from safety system, shut down.

Shut-down, over-speed and emergency stop from safety system, is sent by CAN communication line to the governor which forces the fuel actuator to zero fuel position.

2.12.7 Slow down function, input from safety system.

Slow down function is included as standard in the digital governor system. This function is activated when the input signal for slow down from safety system is active, and limits the rpm below the slow down level, which are an adjustable parameter.

2.12.8 Manual RPM and FUEL limiter functions.

Manual rpm and fuel limiting functions is included as standard in the digital governor system. A limit for maximum rpm or maximum pump index allowed may be set by the operator, from the ACP on the bridge or in control room

2.12.9 Cancel limiters function. The fuel limiters for scavenging air and torque may be lifted by 10% from either the remote control system or from the switch in control room console. It will also cancel manual fuel and rpm limiter.

2.12.10 Load change dependent lubricator function (Option)

The governor may as an option control the load change dependent lubricator function provided for the MAN B&W engines. The governor will operate a solenoid valve on the lubricator system, which increases the amount of lubricator oil when a distinct and permanent load change is detected.

2.12.11 Power loss (black out) Fuel rack will be blocked in last position in order to maintain speed and thrust When power is restored the governor will check actual engine speed and speed set point. And then automatically restore normal regulation.

4 MAINTENANCE

4.1 Introduction This chapter explains how to keep the system in good working order and what to do if the system fails. The following subjects are covered:

• Overview

• Unit replacement

• Preventive maintenance

• Troubleshooting of all parts of the system

4.2 Overview This maintenance chapter is intended for trained maintenance technicians or engineers with experience of electronic and digital circuits, computers and electro mechanical design. The level of information is based on Kongsberg Maritime maintenance philosophy: The onboard technical personnel shall, with the help of the documentation and the system’s built-in test functions, be able to identify malfunctions, locate the fault, and replace major parts, modules and components on a “Line Replaceable Unit” (LRU) level. He/she will however not attempt to repair the LRUs.

Note Cleaning with abrasive material or strong chemical cleaning solutions is not recommended as these may damage the system.

4.3 Unit replacement

Warning Turn power off before replacing any parts!

Note AutoChief C20 units are not field repairable. Any attempt will void the warranty.

Package faulty units using the box from the replacement unit and send it to Kongsberg Maritime for repair. Refer to page NO TAG for information on how to get in touch with us.


AA-0381-A 103

4.3.1 Recommended tools and documentation

Drawings of the installation. Digital multimeter. Sensor simulator. Screwdriver for wire terminals: Flat 3 x 0.7 mm. Screwdriver for screen termination board: Flat 7 x 1.0 mm. Screwdriver Pozidriv: POZI #1. Cable ties.

4.4 Preventive maintenance

4.4.1 General Kongsberg Maritime recommends the following preventive maintenance routine for the AutoChief C20 Propulsion Control system with process control and power management: Weekly: Clean all operator panels with a dry cloth, and run

the on-line lamp and unit function tests. Clean all filters for units equipped with fans.

3-Monthly: Check rpm pickups 6-Monthly: Check cables and cable entrances, electrical screw-

terminals, fuse connections and plug connections. Yearly: Check and if necessary calibrate the input sensors

and output actuators according to the manufacturer’s instructions.

The Classification Societies and/or the Ship’s Maintenance Plan (or Site’s Maintenance Plan) should be referred to for obtaining a recommended preventive maintenance schedule for test of measuring-points and the alarm-system.


104 AA-0381-A

Kongsberg Maritime recommends that the operation of each unit and its functions is checked after any major maintenance. By major maintenance is understood the removing, testing, calibrating and re-installing or replacement of pressure sensors, temperature sensors etc. After this type of maintenance, we recommend each unit to be re-commissioned according to the instruction given in this manual.

4.4.2 Weekly maintenance This maintenance routine applies to units equipped with lamp and/or function test buttons. Pushing function test buttons will not interrupt normal system operation.

AutoChief Control Panel (ACP), Lever Telegraph Unit (LTU), Pushbutton Telegraph (PBT), Multiple Purpose Panel (MPP) and the multiple Purpose display (MPD) Each week do the following for each of these Units:

1 Clean the surface of the units. Wipe the surfaces with a clean damp cloth. For heavier cleaning, use a clean, damp cloth which has been dipped in a solution of a mild dish detergent and water. Wring out firmly before wiping the unit. Never use cleaning solutions containing spirit or alcohol.

2 Push LAMP TEST. − All LED’s should be lit for about five seconds. − if the test fails, refer to the trouble shooting section.

4.4.2.1 Distributed Processing Units The distributed processing units do not require weekly maintenance.

4.4.3 3-monthly maintenance

Visual inspection of system parts is recommended to prevent malfunctions and to ensure safe operation. For rpm pick-ups : Remove dirt and check distance, while engine is stopped


AA-0381-A 105

4.4.4 6-monthly maintenance Where applicable; check the following parts of the system each 6-month period:

1 Check cables and cable entrances for damage to the cable.

2 Tighten all electrical screw-terminals.

3 Tighten all plug connections.

4.4.5 Yearly maintenance Visual inspection of system parts is recommended to prevent malfunctions and to ensure safe operation. Each year, check and if necessary calibrate the input sensors and output actuators according to the manufacturer’s instructions. In general, it is not necessary to re-calibrate sensors if the input signal is correct. Compare the input signal to this system, with the input signals on other systems or local gauges.

In particular for the fuel rack : check max fuel position on the fuel pumps, and adjust max fuel in governor parameter, while engine is stopped Refer to the Classification Societies and/or the Ship’s Maintenance Plan (or Site’s Maintenance Plan) for obtaining a recommended preventive maintenance schedule for test of measuring-points and the alarm-system. The societies normally recommend a 3-monthly to 6-monthly schedule.

Precautions Observe the following precautions when replacing a faulty Unit. • After replacement be sure that there are no errors with the

new Unit. • When returning a faulty Unit for repair, make a detailed

record of the problem and return the Unit to your nearest sales representative.

• If there is a faulty contact, put some industrial alcohol on a clean cotton cloth and wipe the surface.

Use the following procedure when it is necessary to replace a MC Unit.

1. Make a note of the switch settings of the MC Unit to be replaced.

2. Turn OFF the system power supply. 3. Replace the MC Unit, and reconnect the wiring as before. 4. Set the switch settings for the MC Unit. 5. Turn ON the system power supply.


116 AA-0381-A

4.6.4 How to replace the ELACT

Perform the following procedure

1. Replace the ELACT

2. Perform origin teaching (if using position control). • When replacing the ELACT, the ELACT specific origin

position (Z-phase) may slip, so be sure to perform origin teaching.

• Refer to the manual for the position controller you use for how to perform origin teaching.

3. Set up the absolute encoder (ABS). • If using ELACT with an absolute encoder, when

replacing the ELACT, the absolute data in the absolute encoder will be cleared, so you need to set up the data again. Also, the rotation limit data will be different from before you replaced the ELACT, so initialize the Motion Control Unit settings.
