To obtain the best engine performance, it is essential not to deviate from the mission profile for which it was produced and set up. The engine must not be used for purposes other than those stated by the manufacturer. IVECO MOTORS is willing to examine any need for particular installations beforehand. Use of an electronically controlled injection system, in providing the engine with performance benefits, requires that the installer and maintenance specialist comply with some fundamental rules, which will become more and more commonplace as use of such equipment becomes progressively more widespread. Boat outfitters and maintenance specialists are invited to closely follow the instructions contained herein. No modifications to the engine, its accessories and components, are allowed.

Failure to comply with the instructions that follow shall void the warranty and relieve IVECO MOTORS of all liabilities.

For personnel safety

Specialists and installers are cautioned to comply with workplace safety rules and to adopt prescribed individual protection devices when working.

o Drain the cooling, lubrication and fuel lines only after

the fluids have duly cooled. The pressurized cap of the water line may be opened only after the engine has duly cooled.

o Batteries contain a highly corrosive sulfuric acid solution:

must never be upset and must be handled with the utmost caution to prevent spillage. Ensure that the battery compartment is adequately ventilated.

Handling

The engine must be handled by experienced personnel, using the prescribed tool or a rocker arm that keeps the lifting lines parallel and with adequate equipment in terms of capacity and size. The two eyebolts provided for lifting the engine alone must always be used simultaneously.

Installation

o Knife switches or battery breakers may be used on the

power supply line of the engine electronic unit, provided they are not used to shut the engine off.

o Do not modify the wiring harnesses; their length may

not be modified: use only available extensions.

o Do not use electronic device wiring harnesses not com-

pliant with the IVECO MOTORS directive, in terms of length, type of conductor, location, clamping, connection of the shielding and ear th braids.

o To avoid any interference, the wiring harnesses of the

different on-board electronic devices must follow different paths from those of the engine electronic systems.

o Do not connect any extraneous user device to the

engine electrical equipment.

o Do not place voltage across the boat’s on-board electri-

cal system without first verifying that there are no short circuits.

o Do not branch pipes off to draw fuel from the engine

supply lines.

o Do not make any change to the engine’s hydraulic cir-

cuits and components.

o Do not execute arc welding operations before removing

the electronic units from their seating, placing them at an adequate safety distance.

o Do not subject electronic units to temperatures exceed-

ing 80 °C.

o Do not paint electrical components and their connec-

tions.

o Do not alter the data contained in the engine control

electronic unit.

o Comply with prescribed procedures and torque values

when tightening threaded elements.

Start-up

o Ready the engine following the procedure set out in

Chapter 17.

o When starting the engine the first time, have suitable

means available to cut off air intake in case of a runaway condition.

o Start the engine after ensuring that it is complete with

every part specified by the manufacturer and required by the installation, without attempting to star t it with caps and occlusions to the lubrication, cooling and fuel feed lines.

o Check that the fluid lines are perfectly sealed, especially

lines for fuels and lubricants, which may cause fires and consequent harm to persons and equipment.

o Make sure that the various pipelines are not in contact

with warm surfaces or moving parts.

o The installing yard is required to carry out tests to verify

the functional compatibility between the electrical-electronic equipment of the engine and the other electronic equipment present on the boat.

Tests and tuning up

o Never disconnect the batteries when the engine is

running.

o Remove the electrical connections from the batteries

before any operation on the electrical system.

o Ensure that the battery terminals comply with the exact

polarity, are properly tightened and protected against accidental short circuits and corrosion phenomena.

o Do not connect or disconnect electrical connections

when electrical power supply is present.

4. GENERAL INSTALLATION CRITERIA

Accessibility

The engine must be located in such a way as to allow filling and draining engine liquids when doing servicing operations. Moreover, the relay box and the diagnostic push-button present on it must be accessible, also when underway.

Anchoring

If anchoring is accomplished by interposing shock mounts, they must be able to support the engine’s mass and the longitudinal thrust exerted by the propeller shaft in motion. If rigid mounting is adopted, particular care must be given to support alignment and co-planarity. Information on dimensions and fastening values are provided in the “Installation Diagram”.

Combustion and ventilation air

Compliance with prescriptions on the quantity of air required for combustion and ventilation assures a regular operation of the engine even in adverse conditions and it enables to deliver its maximum design power (1).

Sea water line

It must be provided with an intake capable of preventing the entr y of foreign bodies into the suction pipes. Between the intake and the pump, it is best to interpose a gate to be closed in emergencies or for extended idle periods and a filter to stop the smaller impurities; it is also recommended to install a suitably dimensioned and easily replaced zinc anode. The engine sea water line was provided by the manufacturer with protection anodes to be replaced periodically. The rubber hoses positioned along the pipeline shall be sufficiently rigid not to create choked areas caused by crushing (1).

Engine pre-heating

If the engine usage profile requires immediate delivery of power at the highest rpm’s, it is recommended to install an auxiliary pre-heater on the closed cooling loop.

Exhaust gas discharge

The exhaust gas discharge conduit shall be compliant with the guidelines contained in the IVECO MOTORS publication “Guide to the installation of marine engines”; it also provides indications to compute the dimensions of the exhaust pipelines, which is the Yard’s responsibility.

Electric - electronic equipment

Provide a suitable arrangement of the engine control electronic unit, of the relay box and of the possible optional electronic units, referring to the dimensions and position of the wire harnesses and their connectors. Both units must be anchored in such a way as to dampen the vibrations and stresses undergone by the hull while underway and/or induced by the engine’s operation.

(1) The EDC engine electronic control is programmed to

reduce maximum deliverable power if the operating parameters measured by the sensors show that critical conditions have been reached, and if exceeded the engine could be damaged.

7. FUEL LINE

For the installation, the following connections are required:

- from the tank to the pre-filter

- from the pre-filter to the pump inlet

- from the fuel discharge outlet to the tank

Pre-filter

The pre-filter with priming pump, supplied separately from the engine, must be fastened near the tank, in a relatively low point of the line to allow for easy replacement of the filtering cartridge and/or the operation of the hand pump. Avoid the use of additional mesh or paper filters along the feed lines between pre-filter and engine. To avoid introducing impurities in the feeding lines inside the engine, do not place filter cartridges pre-filled with fuel in the system.

Materials’ Characteristics

The fuel tank and the suction and return assembly must withstand the continuous abrasion caused by a flow of fuel oil of 250 l/h at a temperature of 120 °C without noticeable deformation or wear or release of material. Use of metal tanks, preferably made of iron alloys, is allowed, provided

they are connected to the negative terminal of the battery to prevent the accumulation of electrostatic charges. Tanks must be provided with vents to avoid exceeding an internal pressure of ± 5kPa (± 0.5 m of H2O column); their shape and the suction assembly must be such as to assure a suction at the maximum longitudinal and transverse inclination allowed for the boat, with a residual quantity of fuel oil considered “reserve”. The suction inlet should be positioned in such a way as to avoid taking in sludge. The return flow must be in such a way as to facilitate the mixing of the returning fuel with the fuel in the tank. If the tank is lower than the filter, then the return pipe must always be submerged. The pipes and union fittings of the fuel line must withstand a fuel oil flow rate of 250 l/h at a temperature of 120 °C and a pressure of 3 bar (300 kPa) without noticeable deformation, wear or release of material. Metal tubes, preferably made of iron alloys, are recommended, taking care to connect each individual segment to engine ground to avoid the accumulation of electrostatic charges and inserting a vibration damper elastic joint on each segment. The pipes used must be certified according to the relevant Countries’ rules or to the standards issued by classification Bodies.

Figure 10

The electrical equipment of the engine comprises a series of components provided separately from the engine to enable an easy and diversified installation, according to the Yard’s design choices. The need to make accessible, at sea or underway, the controls to the electrical components and to the connector for diagnostics contained in the relay box may be met through different installation arrangements. Along with the coupling of all connectors provided in the wire harnesses, completing the installation also requires the connecting wire harness (12) for the sensor for the presence of water in the fuel (13), to complete the power line and to connect the accumulator to the engine wire harness. To obtain the engine stop if stressed function simply connect the ECF and ECM connectors to each other (these are present on the wiring of the new model).

The connection of the +B terminal of the alternator to the positive +30 terminal of the electric starter motor must be achieved with a conductor having a cross section of at least 10 mm2. The connection of the positive +30 terminal of the electric starter motor to the positive pole of the batter y, achieved with a conductor having a cross section of at least 70 mm2, allows to obtain, as shown in the figure, the simultaneous connection of the alternator to the battery. The connection between the engine ground and the negative pole of the battery must be achieved according to the guidelines provided in the Engine electrical ground paragraph.

CAUTION

If magneto-thermal protecting breakers are inserted, they must not be used to stop the engine and in any case they must be activated only a few seconds after shut-down.

Supplementary services battery

To assure that the engine can be star ted with a sufficient quantity of energy, it is advisable to provide for the installation of a supplementary battery, dedicated to supplying power to the on-board electrical services. The power line to recharge it may be constructed according to the indications provided in Chapter 24.

If one engine is installed

The battery used for services may be recharged interposing on the power supply line a relay actuated by the recharge signal of the alternator’s electronic regulator (D+).

If two engines are installed

The presence of two generators allows to keep the recharging functions separated: the generator (G1) recharges the battery (AC1) dedicated to star ting both engines and powering both electrical/electronic control circuits, whilst the generator (G2) recharges the battery (AC2) used to power the services. In two-engine applications, it is essential to connect the engine grounds to a common potential; the solution proposed in Chapter 24 fully complies with this need, assuring the full functionality and independence of the two circuits.

To anchor the grounding terminal to the engine, proceed as follows: Completely remove the conducting paint from both parts constituting the connection, using mechanical means or suitable chemical product; if the anchoring operation is to take place on superficially treated parts, completely remove the anaphoretic paint with mechanical means, obtaining a smooth support surface. Apply a uniform layer of BH44D paint (IVECO standard 18-

1705) with a brush or spray gun. Join the parts constituting the grounding note within 5 minutes from the time the paint was applied.

This is accomplished through the power supply line of the electric starter motor and connection to the +B of the alternator. The electronic regulator of the alternator that equips the engine allows an effective control over the battery recharging operation. If, due to installation requirements, the batteries need to be positioned at a distance from the engine, we recommend increasing the cross section of the power line conductors and verifying recharging effectiveness by measuring voltage across the batter y poles.

The connection of the central electronic unit, ECU, to the components of the EDC system is achieved by means of three connectors to subdivide the wiring harnesses, thereby favoring a quicker identification of the lines during testing operations. The different connectors are polarized and provided with levers to favor the connection and disconnection operations and assure proper coupling. They are dedicated to the following functions:

o Connector A for engine mounted components

o Connector A1 reserved for electro-injector connection

o Connector A2 for boat side connections

Relay box

This shall be installed and anchored in such a way as to dampen the vibrations and stresses occurring when underway, and they shall be accessible during ser vicing operations and when underway. The electrical commands positioned on the panel allow to control engine starting and stopping (2) directly from the engine room, while excluding any possibility that anyone may involuntarily star t the engine from the bridge (1), during servicing operations. Among the controls present on the panel are also the push-button (3) and the “blink code” light indicator (4), useful to obtain, also while underway, indications that will lead to identify failures or improper engine operating conditions (see Chapter 20).

On the relay box is located the multipolar connector, protected by a screw-on lid (5), for connection with the computerized diagnostic tools prescribed by IVECO MOTORS (see Chapter 20).

Inside the box, anchored to a printed circuit board, are present the power management relays of some components and the elements that protect the electrical lines against short circuits or excessive current absorption. These components perform a similar function to that of fuses, almost totally avoiding the need to restore the electrical continuity of circuits subjected to an anomaly condition. These components are able to limit and eliminate shor t circuit currents without melting, restoring their own and the circuit’s electrical continuity, once the cause of the anomaly is removed.

CAUTION

During the year 2005, some modifications were made to the internal circuits of the relay box and to the wiring. These modifications make incompatible and harmful the use of the components supplied now together with the components supplied before. Please refer to the instruction shown in Chapter 8.

The indications and alarms module comprises the indicator lights and the electronic alarm interface, timing and storage circuit. It is programmed in such a way that when it is powered, all indicator lights are lighted, with the exception of those for “pre-lubrication”, “pre-post heating” and “EDC” failure and a sound signal is emitted by the buzzer. The sound alarm may be silenced before the end of the test, acting on the appropriate control. During the star ting phase and for the subsequent 15 seconds, needed to stabilize the low oil pressure signal, all the module’s functions are inhibited; once this time interval has elapsed, every alarm state detected by the sensors will cause the associated indicator to be lighted and the buzzer to be powered; the exceptions are the “pre-lubrication” and “prepost heating” indicators, given only visually. When a new alarm state is detected, the indicator light will flash to highlight the occurrence with respect to any others which may be ongoing at the time. When the sound alarm is shut off, the light indicator will remain lighted and the alarm will be stored until the engine is stopped.

The standard set-up of the N40 ENT M25, N60 ENT M37 and N60 ENT M40 provides for use of the indicators SAC, SS, SIFA, SATA, SBPO, EDC.

Installation

In order to drill holes on the area where the panel is to be mounted, refer to the dimensions indicated in Chapter 11.

Operation of the panel

After completing the electrical connections and engine preparation, perform the tests required for the first star t, as described in Chapter 18. Verify the proper operation of the panel, proceeding as follows:

o Make sure that the “ENGINE ROOM / BRIDGE” switch

of the Relay Box is in the “BRIDGE” position, then turn the key switch to the first position and verify that the instruments are powered and the indications and alarms module runs the alarm test for about 5 seconds according to the procedures set out below.

o Once the test is complete, only the indications pre-

scribed for the engine not running must remain lighted: e.g. “alternator charge” and “low oil pressure”; the analog instruments must provide values consistent with the relevant physical parameters.

Testing the engine start function

Turn the key switch to the second position and keep it in it until the engine has started, then release the switch, which will stably return to the first position; after releasing the key, the switch may be brought back to the starting position only after the switch is returned to the resting or zero position.

Checking indications

After starting the engine, verify whether the operating modes of the indications and alarms module are similar to those set out below. Using appropriate measuring instruments, verify the consistency of the indications provided by the analog instruments.

NOTE Do not disconnect the connector 14 (see Figure 18) to avoid wrong fuel filter clogging alarm indication.

Verify the indication of the panel revolution counter, comparing it with the one measured by a reference instrument; if the indication is different, proceed as described below.

Testing the engine stop function

The engine is stopped and the panel is disabled by returning the key switch to the resting or zero position. If the engine stopping function if stressed is present, press the stopping button situated on the board. This function is authorised only if the ECF and ECM connectors (present on the new model wiring) have been connected to each other.

The JD connector enables to use an electronic engine rpm management instead of the system provided on the engine. If this solution is used, the throttle position sensor, situated on the engine, will remain electrically connected but not used and the EDC Central Unit will manage engine rpm according to the voltage signal applied to the terminals of the JD connector. In case of a fault in the electronic throttling system, the engine rpm may be managed in emergency condition, mechanically operating the sensor lever positioned on the engine. The connection requires a METRI PACK 150 four-way connector with male terminals.

Installation

In order to drill holes on the area where the panel is to be mounted, refer to the dimensions indicated in Chapter 14.

Operation of the panel

After completing the electrical connections and engine preparation, perform the tests required for the first star t, as described in Chapter 18. Verify the proper operation of the panel, proceeding as follows:

o Make sure that the “ENGINE ROOM / BRIDGE” switch

of the Relay Box is in the “BRIDGE” position, then turn the key switch to the first position and verify that the instruments are powered and the indications and alarms module runs the alarm test for about 5 seconds. During this phase, all indicator lights must be lighted, with the exception of those for “pre-lubrication”, “pre-post heating” and “EDC failure”. A sound signal must be emitted by the buzzer ; it may be silenced before the end of the test, pressing the push-button on the panel.

o Once the test is complete, only the indications pre-

scribed for the engine stopped must remain lighted: e.g. “alternator charge” and “low oil pressure”; the analog instruments must provide values consistent with the respective physical parameters.

Testing the engine start function

Turn the key switch to the second position and keep it in it until the engine has started, then release the switch, which will stably return to the first position; after releasing the key, the switch may be brought back to the starting position only after the switch is returned to the resting or zero position.

Checking indications

After starting the engine, verify whether the operating modes of the indications and alarms module are similar to those set out above. Using appropriate measuring instruments, verify the consistency of the indications provided by the analog instruments.

Testing the engine stop function

The engine is stopped and the panel is disabled by returning the key switch to the resting or zero position. Check that the ECF and ECM connectors (present on the wiring of the new model) are disconnected; the digital board is not equipped with the engine stopping button and consequently it would not be possible to stop the engine with the key commuter with the activation of the engine stop if stressed function.

Programming accessory functions

The following programming operations are required when the panel is first operated:

o The hours of the maintenance interval relevant to the

characteristics of the engine in use.

o The maximum quantity of introduction, necessary to

compute fuel consumption.

With reference to Figure 27, proceed as follows:

o Holding down the “Programming” (10) and “Slide-down

selection” (11) push-buttons, positioned on the panel, turn the key switch to the first position and wait for the display to show the value of the maintenance interval set previously (e.g., 200 hours).

o Release the push-buttons and set the hours of the

time interval, indicated for oil replacement, provided on the operation and maintenance manual; the operation is completed by repeatedly pressing the “Slide-down Selection” push-button (11) until the number that is selected and highlighted by flashing is correctly set, then operating the “Programming” push-button (10) to select the number to set.

o Press and hold the “Programming” push-button (10)

until the display shows the maximum introduction value, set by default to the value 10 mg/strk, then release it.

o Set the number for engine calibration, obtaining it from

the table that follows, proceeding as described in item

2.

o Press and hold the “Programming” push-button (10)

until the display shows the engine rpm indication.

If programming operations were not performed correctly, the display will show the indication “Err.P”; check whether the electrical connections of the main panel and of the converter module were performed correctly, then repeat the procedure.

Remove the cap from the main panel JE connector and connect the JE connector to the JA connector on the secondary panel, placing the special extension JE-JH cable, available 3, 5 and 7 meters long (see figure 24). IVECO MOTORS standard supply is provided for the installation of the main and secondary board and their simultaneous use with no operation limitations.

Installation

In order to drill holes on the area where the panel is to be mounted, refer to the dimensions indicated in Chapter 14.

Operation of the secondary panel

After completing the electrical connection to the main panel and engine preparation, and performing the tests required for the first start (as described in Chapter 18), verify the proper operation of the panel, proceeding as follows:

o Make sure that the “ENGINE ROOM / BRIDGE” switch

of the Relay Box is in the “BRIDGE” position, then turn

the key switch to the first position, thus enabling the operation of the main and secondary panels.

o Carry out the same tests for the secondary panel as

were carried out for the main panel.

o Disable the secondary panel by bringing the key switch

on the main panel to the resting or zero position.

Testing the engine start and stop function.

With the panel enabled, press the green push-button until the engine star ts, then release it; wait for engine rpm to stabilize before stopping it by pressing the red push-button. The starting and stopping operations can be performed several times and consecutively from the secondary panel

Checking indications

Proceed in the same way as for the main panel.

17. PREPARING THE ENGINE FOR FIRST START-UP

1. Drain the residual 30/M protective oil from the sump.

2. Pour into the lubricating loop only lubricating oil of the type and in the quantities set out in the Refilling Table.

3. Drain the CFB protective liquid from the fuel loop, completing the operations as indicated under item 3. of Chapter 23.

4. Remove the caps and/or seals from the engine intake, exhaust, aeration and venting ports, restoring normal conditions of use. Connect the inlet of the turbocharger to the air filter.

5. Connect the fuel loops to the boat tank, completing the operations set out in item 4. of Chapter 23. During filling operations, connect the pipe returning fuel to the tank to a collecting container, to prevent residues of CFB protective liquid from ending up into the boat tank.

6. Verify and refill engine coolant as prescribed.

7. Remove from the engine the labels with the inscription “ENGINE WITHOUT OIL”.

Although they are extremely important, “common sense” checks such as the exposure of sensitive parts (plastics, wire harness, electronic units, etc...) to heat, and those that for years have characterized the quality of the work performed in the yard, are not mentioned herein. Tests of the proper operation of the engine and the components of the electronic control system may be performed rapidly and with the utmost reliability using specific diagnostic tools, available from IVECO MOTORS Technical Assistance Centers.

Fuel tank suction

Verify the fuel suction at the maximum allowed longitudinal and transverse inclination, with the residual quantity of fuel considered “RESERVE”, such as to cause the reserve indicator light to be permanently lighted.

Throttle lever position sensor

In the positions of minimum and maximum travel, verify the correlation between the position of the throttle control valve on the bridge and the position of the sensor rod, checking:

o That in the resting position the safety switch inside it is

electrically open. Carry out the test with an ohmmeter between the points D and E of the potentiometer connector.

- Value read

∞ Ω = optimal adjustment;

- Value read 1 k

Ω = a better mechanical adjustment of

the resting position is required, to bring the value back to ∞ Ω.

o In the position of maximum acceleration, the rod of the

sensor has reached the mechanical end stop.

Instrument panel

Verify the efficiency of all light indicators, as described in the related Chapters.

19. FIRST ENGINE START

Before starting the engine, please make sure the sea water gate valve is open, check the levels of the lubricating oil and of the engine coolant, and complete venting the air from the fuel feed loop, acting on the hand pump of the pre-filter or with the aid of a dedicated electrical pump. Loosen the vent fitting on the pre-filter and operate the pump until only fuel without air flows out. Tighten the vent fitting and continue pumping during the initial start-up phases. Make sure that the fuel that flows out of the fitting is not dispersed in the environment.

CAUTION

Never attempt to vent the high pressure system, as this is useless and extremely dangerous.

Start-up procedures

The electrical equipment of this engine allows to start it from the “engine room” and from the “bridge”.

NOTE

A few moments after start-up, make sure sea water is correctly drained from the relevant circuit.

Starting the engine from the bridge

This is allowed only if the Relay box switch (1) is in the “BRIDGE” position. Start the engine and let it run until the idling rpm has fully stabilized (see also the Chapters on the instrument panels).

Starting the engine from the “engine room”

Moving the Relay box switch (1) to the “ENGINE ROOM” position (which must absolutely not be done when the engine is running), regardless of the position of the key switch on the indicator and control panel, enables the use of the adjacent STOP - START push-button (2). It will thereby be possible to start and stop the engine with complete independence from the bridge controls. Moving the switch (1) back to the “BRIDGE” position, inhibits use of the “START-STOP” push-button positioned on the Box, allowing the engine to be star ted only from bridge controls.

RPM control

To allow easily to control engine RPM from the “engine room”, a simultaneous acceleration/deceleration function (SET+/SET-), active only when the switch (1) is in the “ENGINE ROOM” position, has been implemented in the “start” function.

Acceleration (SET +)

If, when the engine is running, the “start - stop” push-button is held down in the “star t” position, then engine rpm are progressively increased; the increase ends when the push-button is released, allowing the engine to run at the desired rpm.

Deceleration (SET –)

Moving the “start - stop” push-button back to the “star t” position, after releasing it during the rpm increase phase, a progressive reduction in rpm is obtained; when the push-button is release, the function is inhibited and the rpm reached at that point is maintained.

NOTE: Further action on the push-button will alternatively increase - decrease engine rpm. The “stop” function takes priority and always stops the engine.

CAUTION

Never operate the “BRIDGE - ENGINE ROOM” switch when the engine is running.

Once the first star t-up phase is complete, verify that:

o There are no liquid leaks from the coolant loop pipeline

junction hoses.

o There are no exhaust gas leaks into the hull.

o Complete the instrument panel operation tests as

described in the related Chapters.

o Verify that the power supply voltage across the batter y,

after about 15 minutes with the engine running, is no less than about 13 V.

o Stop the engine and delete any “errors” which may have

been stored in the injection system ECU during the stabilization phases. For the deletion procedure, refer to Chapter 20.

20. EDC ANOMALIES INDICATION

Anomalies indicator light

The ECU continuously monitors, with complex self-testing routines, its own operating conditions as well as those of the components connected to it and of the engine. When anomalies are detected, the alarm indicator light on the indicator and control panel is lighted in manners that provide a first indication on the severity of the problem.

Light off: no anomaly detected or slight anomaly

that does not compromise operating safety

Light on: significant anomaly, allowing to proceed to

a service center

Blinking light: severe anomaly requiring immediate

repairs. If possible, shut the engine down.

Blink code

The emission of the anomaly codes detected during self-testing and stored in the ECU starts after pressing and releasing the “CHECK” push-button on the relay box panel, when the “BRIDGE - ENGINE ROOM” switch is in the “ENGINE ROOM” position The LED located at the side of the push-button and the EDC indicator light on the indicator and control panel will simultaneously signal, with two series of emissions at different frequencies, the blink codes that indicate the anomaly with decimal numbering.

Slow blinks identify the area of the anomaly (engine, injectors, ...), fast blinks identify a specific anomaly.

Every time the push-button is pressed and released, only one of the stored codes is emitted; therefore, the procedure must be repeated until an error indication identical to the first one is obtained, which means the entire error memor y has been analyzed.

If no anomalies are stored, the light comes on when the push-button is pressed and comes off about 1 second after its release, without any subsequent blinking.

Recovery

The recognition of significant or severe anomalies causes the adoption of strategies that allow to use the engine with complete safety, guaranteed by limiting performance within pre-set thresholds according to the severity of the case.

These strategies cause the reduction of the maximum values of torque and power delivered by the engine. In the case of intermittent anomalies, i.e. recognized by the ECU and subsequently no longer present, performance reduction will continue until the engine is shut down. Normal operation will be restored only the next time the engine is star ted, while the anomaly data will be “saved” in the failure memor y.

Error deletion procedure

A. Shut the engine down and keep the key switch in the

“OFF” position for 15 seconds (after run).

B. Approach the relay box. Keeping the “CHECK” diag

-

nostic push-button (3), move the adjacent “BRIDGE

- ENGINE ROOM” switch (1) to the “ENGINE ROOM”, wait for the luminous indicator (4) to switch off position, while keeping the diagnostic push-button pressed for 8 more seconds.

C. Release the push-button and move the “ENGINE

ROOM” switch to the “BRIDGE” position

CAUTION

The mistake deleting procedure is intended to eliminate the information relating to the mistakes from the ECU memory, which happened during previous working periods. The mistakes will not be deleted unless the relating cause has been removed. Please remember that some anomalies can be detected by the ECU self-diagnosis only during a complete engine working cycle.

At the end of this procedure, the codes of any anomalies detected during the engine installation and first start-up operations will be deleted in the ECU. To make sure that no anomaly data remain stored in it, or that there are no other errors in the system, set the “BRIDGE - ENGINE ROOM” switch to the “ENGINE ROOM” position and verify that, when the diagnostic push-button is pressed, the blink code light (4) does not emit any code.

At the end of these operations, return the switch to the “BRIDGE” position

If the ECU signals the presence of errors or operating anomalies, the installation will have to be reviewed to remove the cause of the error or anomaly. Indications for decoding the codes are provided in Chapter 21.

NOTE: The blink code diagnostic procedure provides indications about current anomalies as well as past anomalies that are no longer present when the diagnosis is carried out; therefore, it is absolutely mandatory, at the end of every repair operation, to erase the error memory to prevent anomalies whose cause has already been removed from being signaled in the future.

ECU Temperature

Verify that the temperature of the surface of the electronic engine control unit, after 30 minutes underway at full engine power, is less than +70 °C.

Engine compartment vacuum

Verify that value of ambient air pressure in the engine room with the engine(s) at full load and maximum power output complies with the value specified herein.

Combustion air temperature

Verify that the temperature in the engine room, after 30 minutes underway at full engine power, does not exceed 50 °C and, in any case, does not exceed the value of external temperature by more than 15°C.

Exhaust back-pressure

Verify that the value of back-pressure present at the inlet of the exhaust gas conduit, with the engine(s) at full load and maximum power output, complies with the value specified herein.

Exhaust temperature

Verify that the temperature of the exhaust gases under maximum engine power output conditions is close to the prescribed value. To determine the propeller power absorption cur ve, it will also be possible to obtain the fuel injection values from the ECU parameters by using the IVECO MOTORS tool.

Fuel temperature

Verify that the temperature of the fuel in the low pressure line, while underway at full power and with a stable quantity of fuel in reser ve, does not exceed 70 °C. A higher value would entail a reduction in engine performance. If the tendency to reach the maximum allowed temperature is noted, install a heat exchanger for the fuel.

Pressure in the fuel supply line

To assure the regular operation of the engine and the reliability of the components of the fuel supply and injection system, you need to verify that:

o vacuum in the fuel oil supply line to the low pressure

pump is less than 0.35 bar relative (3500 mm H2O);

o pressure in the fuel oil return line to the tank is less than

0.2 bar relative (2000 mm H2O).

Measures are carried out inserting a “T” junction near the fuel inlet and outlet, taking care to avoid any air suction. Values are read at variable rpm, from idle to maximum, at 200 rpm inter vals. If there are any symptoms indicating the possible presence of air in the fuel supply line, a check may be made by inserting a clear tube, arranged as an inverted U, before the engine inlet junction.

23. PREPARING THE ENGINE FOR LONG IDLE PERIODS

To prevent oxidation to the internal par ts of the engine and to some components of the injection system, if idle periods exceeding two months are expected, the engine needs to be prepared with six-months periodicity, proceeding as follows:

1. Drain the lubricating oil from the sump, after heating the engine.

2. Pour 30/M protective oil (alternatively, oil conforming with MIL 2160B Type 2 specifications) into the engine to the “minimum” level marked on the dipstick.

Star t the engine and let it run for about 5 minutes.

3. Drain the fuel from the injection line and from the filter, taking care to avoid letting the fuel come in contact with the auxiliaries belt.

4. Connect the fuel line to a tank containing CFB protec

tive liquid (ISO 4113) and assist the inflow of the liquid by pressurizing the line and turning the engine over for about 2 minutes, after excluding the operation of the injection system. The required operation may be carried out by directly polarizing the terminal 50 of the electric starter motor with positive voltage 12 V, using a conductor prepared for the occasion.

5. Nebulize 30/M type protective oil at the rate of about 10 g per liter of displacement:

N40 ENT M25 = 40g N60 ENT M37 = 60g N60 ENT M40 = 60g

into the engine

intake, while the engine is turning over

as described above

6. Close with suitable stoppers or seal with adhesive tape all engine intake, exhaust, aeration and venting ports.

7. Drain the residual 30/M protective oil from the sump; it may be re-used for 2 more engine preparation operations.

8. Apply tags with the inscription “ENGINE WITHOUT OIL” on the engine and onboard panel.

9. Drain the coolant, if it has not been mixed with antifreeze and corrosion inhibiting agents, affixing tags to indicate that the operation has been carried out.

If external parts of the engine are to be protected, spray protective liquid OVER 19 AR onto unpainted metal par ts, such as flywheel, pulleys and others; avoid spraying belts, connector cables and electrical equipment.

This option offers the chance, in alternative to that prepared for the engine, electronic management of the engine rev. speed. Installation must take place inser ting the interface wiring (2) between the engine and the wiring of the control panels to which the exterior governor will be connected and the electronic module for converting the electric signals from the lever into electronic information recognisable by the EDC central unit.

If this solution is used the accelerator position sensor installed on the engine will remain electrically connected but unused and the EDC central unit will manage the engine speed according to the power signal applied to the JD connector terminals (3). If the electronic acceleration system fails, it will be possible to manage the engine rev speed in an emergency, by disconnecting the JD connector and mechanically activating the lever of the sensor installed on the engine.

If required, a second model of the oil filter suppor t is available. This enables the replacement of the filers when the motor is rotating. During replacement, cartridges are alternatively excluded from the lubrication system in order to guarantee the continuity of the filtering action through the car tridge which is kept in the circuit (see figure 4). The replacement method is described in the “use and maintenance” manual.

1. Connecting element - 2. Commutation lever -

3. Lubricating oil filters.

For the cases where it is required to position the filter in a more accessible place, a connecting element is available. This enables the bypassing of the filter in coming pipes (see figure

5). In order to guarantee that the correct pressure value is maintained in the lubrication system during the installing of remote filters, do as follows:

CAUTION

The filter must be installed in a vertical position. The point where the filter is screwed to the support should always be under the connecting point of the adaptor on the engine.

o For a correct preparation, draw a line from the adaptor

connecting point. The angle between this line and the horizontal surface must be equal to the maximum inclination which the boat can reach on the longitudinal and transversal axis. The screwing point must be positioned under this line (see figure n. 5).

Prescriptions

o Pipes must be adapted to the temperature and pressure

conditions typical of the engine model.

o The pressure fall in each pipe, including its connection,

must be lower than 0,05 bar at 20°C under maximum range conditions.

o The pipes must not touch engine par ts and they must

be fixed at least in two intermediate points between the ends. The lengths of each pipe must not be more than 1200 mm.

o Tubes must be flexible.
