Exhaust system

WARNING

di 63

Carbon monoxide. It could cause nausea, fainting or death.

The exhaust system must be sealed and has to be checked periodically.

WARNING. Carbon monoxide intoxication symptoms. Carbon monoxide may cause nausea, fainting or death. Carbon monoxide is a poisonous gas which can be found also in the engine exhaust. Some of the intoxication symptoms could be: - headache - tiredness, muscle weariness - drowsiness, mental weariness, difficulty in

concentrating, in speaking, blurred vision - stomach-ache, sickness, nausea If you notice anyone of these symptoms, which, by the way, don’t include all the possible carbon monoxide intoxication symptoms, you should go in the open air and keep watchful. You shouldn’t sit down, lay down or get asleep. You should warn other people that carbon monoxide might be present. If the conditions of the person affected do not clearly improve in a few minutes, you should alert the medical staff.

WARNING. The use of copper in the exhaust systems is forbidden. Carbon monoxide may cause nausea, fainting or death. Do not use copper pipes for the engine exhaust system of a DIESEL engine. The sulphurs present in the engine exhaust cause a rapid deterioration of the copper, with the consequent possible loss of exhaust and water.

WARNING. Inspect the exhaust system. Carbon monoxide may cause nausea, fainting or death. For the passengers and the crew safety, install a carbon monoxide detector. To determine the detector correct position, consult the shipyard or the seller. Check the detector before using the generator. Beside the ordinary engine exhaust system maintenance, you should also carry out the carbon monoxide detector maintenance, according to its builder’s instructions. You should always keep the detector at work.

WARNING. When the generator is working, the carbon monoxide may cause nausea, fainting or death.. Carbon monoxide is odourless, colourless, tasteless and it does not irritate. If inhaled, even for a short period, it may cause death. You should follow the following instruction also when you install and put the generator at work. You shouldn’t install the engine exhaust system near places where the exhaust could be intaken by hatchways, portholes or ventilation systems. If the

engine exhaust system is close to the waterline, the sea water could obstruct it or reduce the passageway where the engine exhaust go through. You should never use the generator if the carbon monoxide detector is not active. Pay the utmost attention when you use the generator whilst standing in calm wind conditions, because the engine exhaust could accumulate. Pay attention that the engine exhaust does not return to the boat or goes towards other boats or buildings. Do not overload the boat. Power supply system

WARNING

Explosion. It may cause serious injuries or death.

Take care when handling fuel.

WARNING. Power supply system. Steam fuel may explode and cause serious injuries or death. Steam fuel is extremely explosive. When you handle and keep fuel, you should use the utmost care. Keep fuels in a well-aired zone, far away from open flames, from devices that could produce sparks and away of children’s range. You should never add fuel while the engine is at work, because fuel spilling or sprinklings could start a fire when they contact hot parts or sparks. Refrain from smoking, from using open flames, or from producing sparks near fuel or steam fuel. Keep the power supply lines and the connections sealed and in a good state. Use flexible fittings to avoid breaking due to the vibrations. Do not use the generator in case of fuel losses, with a fuel stagnation or when sparks are present. Repair the power supply system before using the generator again.

WARNING. Emptying of the power supply system. Steam fuel could explode and cause serious injuries or death. Fuel leakage could cause an explosion. When you empty the power supply circuit, you should use a container to collect the fuel. After having emptied the power supply system, you should clean any fuel trace.

WARNING. Installation of the power supply system. Steam fuel could explode and cause serious injuries and death. Fuel leakage could cause an explosion. Do not change the propulsion engines tank or the power supply system. You should install a tank that allows to install one or two drawing pipes as described in the “Installation” handbook. The tank and the installation should be conformable to the existing laws.

di 63

WARNING. Screw thread sealing. Steam fuel could explode and cause serious injuries or death. Fuel leakage could cause an explosion. Use a screw thread sealing to avoid fuel leakage. You should use a petrol, fat, oil, solvent, salt deposit and water resistant sealing.

WARNING. Ignition-protected equipment. Steam fuel could explode and cause serious injuries or death. Steam petrol could cause an explosion. The US legislation “USCG Regulation 33CFR183”, for example, wants all the electric devices (remote panels, wharf commutators, etc.) to be “ignition protected” if installed in places where petrol or gas fuels are present. The above listed devices are NOT ignition protected and are not certified to operate in a place at explosion risk like an engine room or near tanks. The best rooms to keep these devices are the living rooms, the bridge and the other rain and sea water-protected rooms.

WARNING. Injector maintenance. The fuel injected under the skin could cause serious injuries or death. Injector maintenance should be carried out by skilled workers. You should pay particular attention during the injectors maintenance. Injectors spray fuel at a high pressure and fuel could be injected under the skin. You should always use the necessary DPI. In case of injection under the skin, you should consult a doctor straight away.

Use limitations Dynamica generators have been conceived to be used on board of sports crafts, where they have to be installed following the indications written in the related paragraph, in compliance to the laws and regulations in force.

Any use or installation that differs from what indicated in this handbook would cause the end of the guarantee, and would discharge the builder from any responsibility for any possible damage.

The installator, the user and the maintenance men will have to have read completely this manual before operating on the generator.

Generators that are correctly installed generate an electric power with the voltage and the frequency written on their identification label. Any change in the values of the voltage produced and in the frequency can be carried out only by Dynamica authorized staff.

Generators are part of a system that generates and distributes electric board power that has to be planned and carried out according to the European Community existing legislation, Low tension Directive, Electromagnetic compatibility Directive, Machine Directive, or any other possible local stricter law.

Dynamica generators may NOT be installed in environments with an explosion risk, for example where steam petrol or steam battery may be present.

You may not use the generator in parallel with the electric ground system.

You may not use the generator in parallel with other generators.

Any other use of the generators, if not expressively authorized by Dynamica through a written document, is forbidden. For example, they can’t be part of the structural elements of the boat and may not be used as point of support, stair component, supports, plugging.

Installation

Warnings

WARNING. Generator handling and positioning. The generator weight could cause serious injuries or death. Generators possess a lifting eyebolt which may be used in every handling operation. The eyebolt is fit to lift just one generator, and its use for different purposes is forbidden. You should use proper lifting tools.

WARNING. Inflammable materials. A fire could cause serious injuries or death. Fuels and steam fuel are inflammable and explosive. You should handle them with care in order to reduce the risk of fire and explosion. You should equip the room where the generator is placed or the adjacent room with a fire extinguisher fit for the electric equipment in use. You should also instruct the staff on how to use the extinguisher.

WARNING. The use of copper in the exhaust systems is forbidden. Carbon monoxide could cause nausea, fainting or death. You shouldn’t use copper pipes for a DIESEL engine exhaust system. The sulphurs in the exhaust cause a rapid degeneration of the copper, and a consequent possible exhaust and water loss.

WARNING. While the generator is working. Carbon monoxide could cause nausea, fainting or death. Carbon monoxide is colourless, odourless, tasteless, non – irritant and may cause death if inhaled even for a short period. To install the generator and to make it work, you should follow also the following instructions. You shouldn’t install the engine exhaust in places where steams might be intaken by hatchways, portholes or ventilation systems. Should the engine exhaust be close to the load waterline, sea water could obstruct the exhaust or reduce the engine exhaust passageway. You should never use the generator if the carbon monoxide detector is not active. You should pay the utmost attention when you use the generator while standing still with no wind blowing because engine exhaust could accumulate. You should pay attention that the engine exhaust does not get back to the boat or goes toward other boats or buildings. The boat shouldn’t be overloaded.

CAUTION. Connect the electric equipment on ground. Electricity could cause serious injuries or death. Electrocution, usually called “electric shock”, is always possible when you deal with electricity. Open the breakers of every electric power supply BEFORE you start operating on the equipment. You should prepare the installation in order to be able to connect on the ground all the equipment, in compliance to the law regulations in force. Do NOT touch cables or electric devices when you are inside water or on a wet floor, because these conditions are bound to increase the electrocution risk.

CAUTION. Welding on the generator. They may cause serious damages to the electric equipment. Before proceeding with the welding on structural or non structural components of the generator, follow the following procedure: (1) Disconnect the battery removing the negative cable (-) first. (2) Disconnect all the engine electronic control modules, disconnecting the related connectors. (3) Disconnect all the generator electronic control modules, disconnecting the related connectors (4) Disconnect the alternator battery recharge connector (5) Connect the ground pliers of the welder close to the welding position.

di 63

Sea socket and out board exhaust

To install a generator you need a sea socket for the inflow of the cooling water and an outboard exhaust system.

You need to plan and carry out with care the position of the generator, of the sea socket and of exhaust system.

There are two types of sea sockets:

direct socket, also called static baffle socket, also called dynamic or “spoon”

CAUTION. Don't use baffle socket .

Installing gensets you MUST use direct socket. Any installation that differs from what indicated in this handbook would cause the end of the guarantee, and would discharge the builder from any responsibility for any possible damage.

The generator cooling system intakes water from the sea socket, makes it circulate in the cooling circuits and then puts it, through an opening of the exhaust mixer, in the exhaust circuit.

During the generator normal functioning, the engine exhaust pressure expels water from the exhaust ducts, thus avoiding accumulations.

When the boat is moving, the sea socket may generate pressure, or depression, in order to help, or obstacle, the circulation of the cooling water and could also make sea water circulate when the generator is switched off.

This dynamic behaviour might bring about a side effect, because the water could overtake the pump and reach the muffler even when the generator is stopped, and, due to the engine exhaust pressure, you won’t have the emptying effect.

If the water in the exhaust duct overtakes the level of the generator exhaust mixer, you will have a sea water intake in the exhaust ducts of the first engine, and thus in the engine cylinders This would bring about serious damages to the engine.

In a typical installation, the pressure generated in the sea socket according to the boat speed, is the one illustrated in the following figure. As you may see, some types of sea sockets, or some installations, may generate depressions and could obstacle the generator sea water intake pump functioning, causing a overheating of the generator.

efore connecting the generator to the sea socket, you should check the real pressure generated by this socket during the navigation, in order to determine the need of siphon – breaks and to not exceed the maximum prevalence of the sea

water pump.

Some of the carbon monoxide intoxication symptoms could be: - headache - weariness, muscle weakness - tiredness, mental weariness, difficulty in concentrating, in talking, dimmed vision - stomach-ache, sickness, nausea Should you notice anyone of these symptoms, which do not, anyway, include all the possible carbon monoxide intoxication symptoms, go to the open air and remain watchful. Do not sit down, do not lay down and don’t fall asleep. Warn other people of the carbon monoxide presence. Shouldn’t the conditions of the person affected by the intoxication get visibly better, in a few minutes, you should alert the medical staff.

WARNING. Check the engine exhaust system. Carbon monoxide could cause nausea, fainting or death. For the crew and the passengers’ safety, you should install a carbon monoxide detector. You should refer to the shipyard or to the seller to determine the correct position of the detector. Check the detector before using the generator. In addition to the normal maintenance of the engine exhaust system, you should carry out the carbon monoxide detector maintenance as well, following its builder’s instructions. You should keep the detector always at work.

WARNING. During the generator functioning. Carbon monoxide could cause nausea, fainting or death. Carbon monoxide is a odourless, colourless, tasteless and non-irritant gas which could cause death if inhaled even for a short period. You should follow these instructions when you install the generator and put it at work. You shouldn’t install the engine exhaust in places where the steams could be intaken by hatchways, portholes or ventilation systems. Should the engine exhaust be close to the load waterline, sea water could obstruct the exhaust system or reduce the engine exhaust passageway. You should never use the generator if the carbon monoxide detector is not active. You should pay the utmost attention when you use the generator while standing still, with no wind blowing, because engine exhaust could accumulate.

Detecting the anomalies

Warnings

WARNING. During the generator functioning. Carbon monoxide could cause nausea, fainting or death. Carbon monoxide is a odourless, colourless, tasteless and non-irritant gas which could cause death if inhaled even for a short period. You should follow these instructions when you install the generator and put it at work. You shouldn’t install the engine exhaust in places where the steams could be intaken by hatchways, portholes or ventilation systems. Should the engine exhaust be close to the load waterline, sea water could obstruct the exhaust system or reduce the engine exhaust passageway. You should never use the generator if the carbon monoxide detector is not active. You should pay the utmost attention when you use the generator while standing still, with no wind blowing, because engine exhaust could accumulate. You should pay attention that the engine exhaust does not get back to the boat or go towards other boats or buildings. The boat shouldn’t be overloaded.


Preliminaries

Before trying to find out the causes of any breakdown, proceed with the daily generator maintenance, as described in the previous paragraph, in order to make sure that all the necessary conditions for a correct functioning of the generator are present.

Structural typology

The generators described in this handbook use a first engine, power supplied by diesel oil and a two-poles generator.

The electric machine, of the brushless type, is self-exciting through an auxiliary stator winding and a condensator in succession.

The voltage regulation with the charging variation, is determined by the voltage induced on the rotor, straighten by the rotor diodes.

The stator is connected to the engine base, through a special bell-like support which covers the flywheel.

The rotor is connected to the engine flywheel through a conic coupling on one side, and, on the other side, it is supported by a bearing inserted in the flange of the stator framework.

The stator framework is connected through tie-rods that go through the bell that covers the flywheel.

Because of this structural typology, the generator can’t operate separated from the thermal engine.

Voltage and frequency adjustment


WARNING. Operations on the condenser. Electricity could cause serious injuries or death. When you handle charged condensers, you risk electrocution. Discharge the condenser, after having disconnected it from the generator, putting the condenser terminals in short circuit among them. Do not proceed with this operation in risky environments, where explosions might occur, where fuel stagnation, steam fuel or batteries are present.

WARNING. Generator voltage test. Electricity could cause serious injuries or death. Only skilled workers should check the equipment in tension. You should use tools and feelers with nominal values that suit the measures that you are about to carry out. Follow the tools builder’s instructions You should wear the appropriate DPI. Observe the following precautions: (1) take all the jewels off (2) stay on a dry surface, made up of insulated materials. (3) Do not touch any metal component or material of the conductor Be prepared for the automatic start of the generator

How to proceed

You should always carry out the voltage test at the nominal rotation speed.

Generators are usually adjusted by the builder to give a voltage 5-6% higher than the rated one, in order to keep, at every charge, the voltage within the tolerance range.

Light differences of the output voltage may depend from the fact that the rotation speed differs from the nominal one: you should always keep in mind that the output voltage, with an equal charge, is directly proportional to speed.

If you intend to correct the given voltage at a certain charge and at a certain speed, you should change the condenser capacity: if you increase the condenser capacity, the voltage increases, if you decrease the capacity, the voltage decreases.

WARNING You are not allowed to change the voltage produced by the generator, under whatever charging condition, more than 10% of the rated value.

Bearings

The generators bearings are self lubricant and do not require maintenance for a functioning period of 15000 hours.

When you proceed with a general overhaul of the generator, you should substitute the bearings.

Rotor test

WARNING. Disconnect the generator. The generator unexpected starting could cause serious injuries or death. Before you start to operate on a generator or on the connected accessories, disconnect the generator proceeding in this way: 1) In order to switch the generator off, put the general switch on the OFF position or put the START/STOP switch on

the STOP position or push the STOP button. 2) If present, take away the battery charger supply. 3) Disconnect the battery cables, disconnecting the negative cable (-) first.

di 63

You should follow these instructions if you want to be sure that the generator couldn’t be started by charge frames, remote start/stop buttons, remote computers or other devices. How to proceed

On the rotor you may carry out the following controls: insulation, windings continuity and windings electric resistance. To carry out these rotor tests you have to disassemble the rotor.

Insulation control

Disconnect the two rotor diodes, the so-called field diodes, and the varistors.

Check the insulating resistance among the two windings and between each winding and the ground.

To carry out this control you need a tool that suits the measure of the electric insulation, such as a 500VDC MEGGER.

Figura 9

The windings with a resistance to the ground and among them superior to 1M� are considered sufficiently insulated.

Should you have a lower value, this might be due to the humidity on the windings. In this case, before proceeding with the rotor substitution,, you may try to dry up the rotor placing it in the oven at 80°C, or by making a current circulate in the windings in order to increase their temperature to this value for about ten hours. At the end of this drying process, check again the insulation. If the insulation hasn’t been restored to a value superior to 1 M�, you should proceed with the rotor substitution.

Continuity check

Using an Ohmmeter, check any eventual interruption of the rotor windings.

di 63

Figura 10

Shouldn’t you have an Ohmmeter, you may check the continuity of each rotor winding using a 12V lamp and a12V battery.

Should you notice an interruption of the rotor continuity, you should substitute the rotor.

Figura 11

Resistance check

To check the rotor windings resistance, you should use a tool capable to measure correctly resistances with a � fractions value, like a Wheastone bridge or a micrometer, or use a voltmetric method.

Model Rotor resistance at 20°C [�]

EMI 40 6.09 EMI 60 6.99 EMI 80 7.93 Mini 40 2.57 Mini 60 Mini 80

Should the values differ from the above listed values more than ± 10%, you should proceed with the rotor substitution.

di 63

Rotor diodes and varistors check

Once they have been disconnected from the rotor, you may check the rotor diodes with a multimeter.

You should check the diodes direct and inverse resistance. The inverse resistance should be very high, practically an open circuit. The direct resistance should be low. Normally the direct voltage fall is of about 0,7V.

Figure 12

Varistors are voltage transitors suppresser. High voltage peaks that are generated when the charge applied to the generators suddenly changes. They are connected in parallel to the rotor diodes, to protect the diodes.

With a multimeter check, integral varistors have a high resistance, of about one M�, in both directions. You may recognize the defective components because their colour often changes and they could be burned. If you check them with a multimeter, their resistance in no longer around a M�.

Figure 13

Defective diodes substitution

On the rotor there are two diodes, one for each rotor winding. You should make sure to mount the diodes observing their polarity and the identification mark on the rotor.

Stator test

WARNING. Disconnect the generator. The generator unexpected starting could cause serious injuries or death. Before you start to operate on a generator or on the connected accessories, disconnect the generator proceeding in this way: 1) In order to switch the generator off, put the general switch on the OFF position or put the

START/STOP switch on the STOP position or push the STOP button. 2) If present, take away the battery charger supply. 3) Disconnect the battery cables, disconnecting the negative cable (-) first. You should follow these instructions if you want to be sure that the generator could be started by charge frames, remote start/stop switches, remote computers or other devices.

di 63

How to proceed

You may proceed with the following stator controls: insulation, windings continuity and windings electric resistance. To carry out these stator tests, you need to stop the generator and to disconnect the stator cables from the check box terminal board.

Insulation check

Disconnect the generator output clamps from the check box. You should refer to the electric schemes in order to go up back to the markwire codes of the windings to be checked.

Check the insulation among the windings and between the windings and the ground.

You should carry out this control with a tool that suites the electric measure insulation, such as a 500VDC MEGGER.

The windings with a resistance to the ground and among them superior to 1M� are considered sufficiently insulated.

Should you have a lower value, this might be due to the humidity on the windings. In this case, before proceeding with the rotor substitution,, you may try to dry up the rotor placing it in the oven at 80°C, or by making a current circulate in the windings in order to increase their temperature to this value for about ten hours. At the end of this drying process, check again the insulation. If the insulation hasn’t been restored to a value superior to 1 M�, you should proceed with the stator substitution.

Continuity check

With the help of a Ohmmeter, check the eventual interruption of the stator windings.

Shouldn’t you have an Ohmmeter, you may check the continuity using a 12V lamp and a 12V battery.

Should you notice an interruption in the continuity, you should substitute the stator.

Resistance check

To check the rotor windings resistance, you should use a tool capable to measure correctly resistances with a � fractions value, like a Wheastone bridge or a micrometer, or use a voltmetric method.

The windings with an equal output voltage 1-2 and 3-4, should have the same resistance values.

If the values differ from the above listed values more than ± 10%, you should substitute the stator.

Reconnectable alternators, like the in Fig. 14 and Fig. 15, a 115/230 VAC type, possess the primary winding divided in two windings: terminals 1-2 e 3-4.

Alternator excitation

In some cases, after a disassembly or some accident, the rotor could demagnetize itself completely. In this case, the alternator won’t produce any voltage.

You will then need to proceed to the initial rotor magnetization by applying to the line clamps, with the generator stopped, just for an instant, the battery voltage. See Fig. 17

Insert on the battery cable a 10A fusible to prevent any possible short circuit.

Warnings

WARNING. Disconnect the generator. The generator unexpected starting could cause serious injuries or death. Before you start to operate on a generator or on the connected accessories, disconnect the generator proceeding in this way: 1) In order to switch the generator off, put the general switch on the OFF position or put the START/STOP switch on the

STOP position or push the STOP button. 2) If present, take away the battery charger supply. 3) Disconnect the battery cables, disconnecting the negative cable (-) first. You should follow these instructions if you want to be sure that the generator could be started by charge frames, remote start/stop switches, remote computers or other devices.

WARNING. Generator moving and positioning. The generator weight could cause serious injuries or death. Generators possess a lifting eyebolt which might be used in every handling operation. The eyebolt is measured just for the lifting of the generator, and any other use is forbidden. You should use the proper lifting tools.

WARNING. Inflammable materials. A fire could cause serious injuries or death. Fuels and fuel exhaust are inflammable and explosive. You should handle them with care in order to reduce a fire or explosion risk. The compartment where the generator is installed should have a room with a special fire extinguisher to be used on electric devices in tension. You should instruct the staff on how to use the extinguish tools.

How to proceed

Should the equipment be out of order, the Client should bring about a separate collection of the components, without leaving them in the environment.

Steal, aluminium, rubber, plastic, exhaust oils, fuel, coolant, electric wiring, etc. Should be collected separately and sent to the recycling points or to the disposal centres.

To carry out the disassembly operations, you should follow the procedures indicated in this handbook and in the workshop handbook.
