GENERAL DESCRIPTION
1
Diesel generators (generator) are fixed devices, which are equipped with
electric AC generator with diesel internal combustion engine. This engine and
generator are connected to each other directly, and are fixed on a steel frame
by damping props.
The generator is attached to the flange of the crankcase with four bolts. The
transfer of torque from the engine to the generator is provided by the conical
coupling of the generator's rotor and of the motor shaft.
Diesel generators “Vitals” ERS 4.6d and ERS 4.6dt are used as a backup
or emergency source of electric power for single-phase alternating current's
consumers.
These products are made according to the current requirements of the
technology standard and level as well as to the current safety regulations.
They have a modern design, they are economical and safe in operation, are
easy to use and to maintain.
Their operating principle is very simple because the chemical energy of a
diesel fuel, which burns in the chamber of internal combustion engine, is
converted into a mechanical work, and an electric generator, which is
connected with the motor shaft, converts the speed into an electrical current.
Diesel generator is equipped with a control panel which manages the
product, with the system of his condition control and protection from the
accidents.
Distinctive features of the model ERS 4.6dt:
џa noise absorbing cover that reduces sound pressure level when the
engine is operating;
џthe lack of a recoil starter gear.
Description of the main components of the diesel generator is presented
below.

improperly.
PLEASE READ ALL INSTRUCTIONS
In order to use the product safely, you should read the instructions very
carefully. Improper operation of a device or its operation by an untrained
person can be dangerous. Read very carefully about all components of the
mini diesel generator. Learn how to stop the generator's engine if it is
necessary. If the person doesn't follow these instructions, he can have an
electric shock, serious problems with health or even can die.
RISK OF FUEL VAPOR AND EXHAUST GASES
Diesel fuel and exhaust gases inhalation, depending on their
concentration in the atmosphere, can lead to insensibility or death.
If diesel fuel has very long and frequent contact with your skin, it can cause
skin irritation, and exhaust gases' toxicity irritates mucous membrane of
respiratory tract and eyes, because there are a large amount of sulfur dioxide,
aldehydes and smoke particles in these gases.
The consistency of the exhaust gases in the atmosphere varies greatly
and depends on the type of engine, its mode of operation and loading,
technical condition and the quality of the fuel.
When you launch generator in a confined space or a room with limited
access to air, the concentration of emissions is very dangerous for human
health and life. In order to avoid the emissions' accumulation of exhaust gases
you must provide a good ventilation of the room.

Fuel
While refuelling, use only clean, fresh diesel fuel. Filter diesel fuel before
refuelling using silk or let it stand for 24 hours. Do not allow dust, dirt, debris or
water to fall into the fuel and into the fuel tank.
Diesel fuel level in the fuel tank should be checked before starting the
engine of generator. If the engine has just stopped, wait for 4-5 minutes or
more, so that the engine cools down, and only then start the refuelling.
Refuelling should be done only in the way when an airbag remains in the fuel
tank for the possible expansion of the fuel vapor when it is heating. The
maximum fuel level should be 2-3 cm below the lower edge of the filler neck of
the fuel tank.
Fuel filter
Both models are equipped with a fuel filter that allows the selection of fuel
solids and the separation of relatively large mechanical particles and water by
settling them.
A clogged fuel filter can be the cause of difficult engine start, of losing its
power, incorrect operating. In addition, dirty fuel filter can significantly reduce
the life of the engine.
Air filter
There is an air filter with a dry filter element on the engine power, which
condition should be checked before each engine's launch. It is strongly
recommended to check the air filter and change it according to the regulations
(see section 6 of this manual, "Maintenance").
A clogged air filter can be the cause of difficult engine start, of losing its
power, incorrect operating. In addition, dirty air filter can significantly reduce
the life of the engine.

2. Move lever fuel control in the direction of the «RUN» arrow (see fig. 8).
3. Take the starter handle and slowly pull it up until you feel the resistance.
4. Pull down the decompression valve lever («DECOMPRESSION LEVER»)
(see fig. 10).
5. Firmly holding (in two hands) starter handle, pull the entire length of the
cable sharply and vigorously. You should do it carefully in order not to pull
the cable out of the holder. Do this as soon as the engine starts.
Decompression valve lever will return to its original position automatically
when you pull the starter handle.
6. Warm up the engine, letting it operates for 3-5 minutes at the idle speed until
there will not be good paces.
If the engine does not start after three attempts:
џCheck the fuel for the presence in it of mechanical solids and water;
џCheck the condition and cleanliness of the air filter element;
џCheck the oil level in the crankcase;
џRepeat launching.
NOTE!
If there is not enough oil in the crankcase, the engine will not
start. Check the oil level, and, if it is necessary, add oil.

ENGINE LAUNCHING IN THE COLD SEASON
The ambient temperature, which is below 0 °C, causes:
џwhen the viscosity of the oil in the crankcase increases, the resistance of
cranking and the piston, and the rotation of gear transmission increase too;
џwhen the viscosity of diesel fuel increases, the fuel pressure, which is
supplied to the injector high-pressure fuel pump, decreases;
џwhen the energy of storage battery decreases - the torque, which is
developed by an electric starter when the diesel engine starts, reduces.
For reliable diesel engine starting at temperatures below 0 °C:
џuse only high-quality winter fuel;
џdrain the oil from the crankcase, heat it up and pour the warm oil into the
nozzle holes for oil;
џIn order to heat the oil in the crankcase, use pre-heaters, which are based
on the hot water and steam using;
3
џunscrew the plug of the oil engine head hole, pour into the hole 2 sm of
engine oil, tighten the plug and start the engine immediately. During engine
operation the plug must be torqued tightly hold because the engine can
start to suck the dust, that will lead to its failure;
џhold the ignition key on the «START» position after the first outbreaks of
fuel in the cylinder, scroll starting engine for several seconds until you see
flashes (at this time the motor can not be operating on idles, but it can be
operating on lower turnovers);
џpay attention on the exhaust gases. If there are blue pillars of smoke from
the exhaust pipe of the muffler, it is "cold" fuel combustion.
CAUTION!
In order to ensure easy starting engine, do not use an open
flame while heating oil in the crankcase, do not add volatile
liquids to the air intake, such as kerosene, petrol, white spirit,
as this can cause an explosion of fire engine.
ENGINE STOPPING
1. Turn off the electricity consumers and let the engine run at idle speed for 1-2
minutes.
2. Turn off the circuit breaker at the AC power panel.
3. Turn the ignition key to «STOP» (see fig. 9). After that an electromagnet
starts operating, which by cable will activate the motor stop lever.
4. In case of emergency, when the engine stop lever is not activated by the
described method in the preceding paragraph, press the plug on the engine
stop lever down to the «STOP» arrow (see fig. 8).
5. After stopping the engine, close the fuel valve - turn the fuel cock lever
(«FUEL COCK») to position «OFF» («CLOSE») (see pic. 6 and fig. 7).
6. Pull the recoil starter handle slowly (when the engine is completely stop-
ped!) until you feel the resistance (these are the intake and exhaust valves
of the engine), and let the handle go. This will prevent the engine from
corrosion during its storage (only ERS 4.6d model).
ENGINE'S RUNNING
One of the most important moments in the device's exploitation is new
engine's running. If the running of the engine is correct, its service life will
increase considerably.
WARNING!
A sudden engine stoppage could lead to an undesirable
increase in temperature and it shortens engine's life.
WARNING!
When the engine is stopping, decrease its turnovers slowly.
It is forbidden to stop the engine by the decompression valve
lever (only ERS 4.6d model), as this will inevitably lead to
failure of the engine.

Engine's running procedure:
1. Start the engine and let it run at idle for 10 minutes. Stop the engine and
allow it to become completely cool. This procedure must be repeated 5
times.
2. Start the engine and let it run at idle for 60 minutes. Stop the engine and
allow it to become completely cool.
3. The first 25 hours of operation of the device, the load should not exceed
50% of the nominal figure. The work should be carried out by stages. Each
stage should not exceed 3 hours.
4. After 25 hours of the device's operation, replace the oil, after washing the
engine. Fill the generator with 1.65 liters of oil and run the engine for 10
minutes. Drain flushing oil, wash the oil filter and fill with new oil. Use for
cleaning the oil according to the ambient temperature.
BEFORE CONNECTING THE ELECTRIC CONSUMER
џEnsure that electrical appliances which are connected to the generator,
are intact and free of defects. Because there can be an electric shock or
fire;
џMake sure that the total power consumption of all connected electrical
appliances do not exceed the rated output power;
џThe operation time of the generator between nominal and maximum power
should not exceed 5 minutes. Otherwise, this could lead to product failure;
џIf you are using an extension cord, make sure that it is completely
unwound, and cable cross-section corresponds to the connected load. If
an extension cord or a cable has insufficient wire size, it can lead to voltage
drops, cable overheating and instability operation of connected
consumers;
џDo not overload electrical outlets of the generator. Each outlet has that
power, for which it is made. Try to distribute the load evenly between the
power outlets. The maximum current carrying capacity of a single electrical
outlet power must not exceed 16 A.
CALCULATION OF LOAD AND CONNECTION
Connect only single-phased power consumers with an operating voltage
of 230V ± 20% and frequency of 50 Hz to generator's ERS 4.6d and ERS 4.6dt
models.
The rules for calculating the load
1. Starting power of the connected to the generator unit with the highest inrush
current does not exceed the maximum capacity of the generator's product.
2. The total power consumption of all devices (with reactive and active loads)
must not exceed the rated capacity of the generator.
3. To calculate the correct load, you should consider the power factor of the
device.
4. There should be a 20% of power margin for proper and safe operation of the
diesel generator.
5. The power of connected consumers must not exceed the maximum power
socket of generator.
WARNING!
Do not connect the product with the electrical power
consumers, which power exceeds the maximum capacity of
the device.
NOTE!
Many appliances have the so-called inrush current, which
briefly increases the power consumption of electrical
appliances in several times. On this basis, to supply the power
consumers they must get the necessary power to run. Starting
capacity of such devices shall not exceed the maximum
capacity of this generator. The user, who has the highest
starting power, should be connected first to the device.

Consumers of electricity are divided into active and reactive.
Active consumers have the most common load. Consumers have such a
heavy workload entire electrical energy which is converted into heat. For
example: incandescent lamps, irons, heaters, electric stoves, hair dryers, etc.
To calculate the total power of consumers it is enough to combine the power of
these devices (the power is indicated on the device itself).
Consumers have reactive loads, which are provided with an electric motor,
where the energy is consumed in order to create an electromagnetic field.
These customers include pumps, machine tools, power tools, refrigerators,
washing machines, etc. A measure of reactivity is the power factor (cos φ). To
calculate the actual power consumption of reactive generators, the power
must be divided on cos φ. For example: if for an electric drill of 600 W of power
cos φ is 0.8, so its work will require 600 W / 0.8 = 750 W of power. This must be
considered when calculating the total power consumption of consumers
which are connected to the generator. The cos φ value of such appliances is
specified on the label or in the manual of each device.
It should also considered that every generator has its own cos φ. For
example, if the coefficient is 0.8, so for this drill's operation it is required
750 W / 0.8 = 938 watts.
In order to avoid the generator's overloading there should be calculated the
total power of the connected devices, which his not more than 80% of the
nominal power of the device.
You should connect consumers to the generator only when the engine is
running, but the AC circuit breaker must be disabled at this time. Connect the
customer, switch on the AC fuse, and only then start the consumers. The
turning on of several electrical appliances should be done consistently and be
started with a device that consumes the most power.
USING THE DC OUTPUT
ERS 4.6d and ERS 4.6dt generators are with a DC output. Maximum DC
power is 12 V-8,3 A. This output is used to charge the batteries, as well as for
connecting the DC loads.
How to connect the consumer to the DC output
1. Disconnect the AC fuse.
2. Start the engine.
3. Connect two-conductor power cables of the appropriative length and cross-
section of at least 6 mm of each core to the DC terminals. Securely tighten
the clamping nut of the terminals.
4. Observing polarity, connect the power cables to the battery or DC loads.
NOTE!
Generator's ERS 4.6d and ERS 4.6dt models have the
power factor (cos φ), which is equal to 1.
WARNING!
The engine will automatically increase the pace with
increasing load of electric generator.
WARNING!
If there is a short circuit between the terminals the
automatic DC circuit breaker turns off.
WARNING!
While charging, the battery generates toxic flammable
gases. The charger operates only outdoors or in a well-
ventilated area. Avoid the generation of flame and sparks
while charging the battery.
