LUBRICANT
RECOMMENDED OIL
MOSA recommends selecting AGIP engine oil.
Refer to the label on the motor for the recommended
products.
REFUELLING AND CONTROL:
Carry out refuelling and controls with motor at level
position.
1. Remove the oil-fill tap (24)
2. Pour oil and replace the tap
3. Check the oil level using the dipstick (23); the oil
level must be comprised between the minimum
and maximum indicators.
Please refer to the motor operating manual for the
recommended viscosity.
AIR FILTER
Check that the dry air filter is correctly installed and
that there are no leaks around the filter which could
lead to infiltrations of non-filtered air to the inside of
the motor.
It is dangerous to fill the motor with too much oil,
as its combustion can provoke a sudden increase
in rotation speed.
ATTENTION
!
BATTERY WITHOUT MAINTENANCE
Connect the cable + (positive)
to the pole + (positive) of the
battery (after having taken
away the protection), by
properly tightening the clamp.
Check the state of the battery
from the colour of the warning light which is in the
upper part.
- Green colour: battery OK
- Black colour: battery to be recharged
- White colour: battery to be replaced
DO NOT OPEN THE BATTERY.
FUEL
Do not smoke or use open flames during
refuelling operations, in order to avoid
explosions or fire hazards.
Fuel fumes are highly toxic; carry out
operations outdoors only, or in a well-
ventilated environment.
Avoid accidentally spilling fuel. Clean
any eventual leaks before starting up
motor.
ATTENTION
!
Refill the tank with good quality diesel fuel, such as
automobile type diesel fuel, for example.
For further details on the type of diesel fuel to use,
see the motor operating manual supplied.
Do not fill the tank completely; leave a space of
approx. 10 mm between the fuel level and the wall
of the tank to allow for expansion.
In rigid environmental temperature conditions, use
special winterized diesel fuels or specific additives
in order to avoid the formation of paraffin.

COOLING LIQUID
Remove the tap and pour the liquid coolant into the
radiator; the quantity and composition of the liquid
coolant are indicated in the motor operating manual.
Replace the tap, ensuring it is perfectly closed.
After refilling operations, allow the motor to run for
a brief time and check the level, as it may have
diminished due to air bubbles present in the cooling
circuit; restore the level with water.
To replace the liquid coolant, follow the operations
described in the motor operating manual.
Do not remove the radiator tap with the
motor in operation or still hot, as the liquid
coolant may spurt out and cause serious
burns. Remove the tap very carefully.
GROUNDING CONNECTION
The grounding connection to an earthed installation
is obligatory for all models equipped with a
differential switch (circuit breaker). In these groups
the generator star point is generally connected to
the machine’s earthing; by employing the TN or TT
distribution system, the differential switch
guarantees protection against indirect contacts.
In the case of powering complex installations
requiring or employing additional electrical protection
devices, the coordination between the protection
devices must be verified.
For the grounding connection, use the terminal
(12); comply to local and/or current regulations in
force for electrical installations and safety.

SIGNALS AND ALARMS
The EDC 4 (Electronic diesel control) is an electronic system
for the gestion of the diesel engines.
The system includes the gestion of the injection and the
diagnosis function.
The information of the sensors placed on the engine supply
the exact grame of the working situation of the engine and
allow tu the central processor to calculate the exact quantity
of fuel to be injected, besides checking the general conditions
of the engine.
The task of the diagnosis function is to identify and signal
possible disfunctions in the EDC 4 system.
The engine protection is entirely secured by the EDC 4
electronic system while the oder devices of the electric board
direct and check the other components of the generating set,
for example: fuel, battery and reloading system, outlet voltage
and frequency, protection against overloads and short
circuits, etc.
Engine alarms
A disfunction noted by the EDC 4 system is signaled by the
diagnosis warning lamp which lights on: the warning lamp
also lights on for 2 seconds during the starting phase to check
how it works.
To find the fault noted by the system proceed in the following
way:
- disconnect the load;
- press for 1-3 seconds the diagnosis push button;
- the diagnosis warning lamp goes out and an instant later a
twinkling series will begin corresponding to e fault code;
-the list of the fault codes and the reading modes of the codes
are to be found in a detailed way in the engine handbook;
- the system might have noted more than one disfunction; it is
necessary to repeat the operation several times, until the
first code does not twinkle again;
- stop the engine and eliminate all the signaled faults;
- Place the selector SWITCH BOARD in DIAGNOSTIC
position, press again the push button to check that there are
no remaining faults, in this case the warning light will twinkle
twice shortly; otherwise it will repeat the code of the fault not
yet repaired.
Some types of alarms consideres as serious by the EDC 4
system cause the engine to stop immediately.
In these cases to find the fault, one must proceed in the
following way:
- place the selector SWITCH BOARD in DIAGNOSTIC
position;
- the diagnosis warning lamps will come on with an
intermittent light;
- press for 1-3 seconds the diagnosis push button and note
the fault code;
- eliminate the fault and make the checking process.
All the passive (repaired) as well as active (to be repaired)
disfunctions are memorized in the system centre and can be
read by means of the equipment Volvo VODIA given to the
authorized Volvo workshops.
ATTENTION
•The selector SWITCH BOARD in DIAGNOSTIC position
impedes the starting of the engine and with running engine
impedes its stop. Use this position only to detect the faults
noted by the EDC 4 engine system.

INTRODUCTION
The “GECO” equipment entails a control unit for absolutely
modern generators. Its strong holds are the following:
- Large-size graphical display (95x45 mm) to be able to display
all the electrical parameters at the same time (with characters
of 10mm).
- The membrane keyboard has built-in keys with relative
indicator LEDs. It also offers a high degree of reliability and
ideal touch-sensitive keys.
- The HELP key with relative LED that flashes to point out that
a message is to be read
- The use of the dater clock to set the weekly TEST and to
display all the events that occur and that may be shown on
the Display.
- The control of 4 different mains/generator line systems:
•N-L1-L2-L3
•L1-L2-L3
•L1-N-L2 (AMERICAN market)
•N-L1
- Operational temperature range from -20 to + 60°C
- Protection rating IP64
- 5 possible languages: Italian-English-French-German-
Spanish
- Generator protection against OVERLOADS and SHORT-
CIRCUITS with setting of the rated current of the generator,
setting of the short-circuit current in percentage of the rated
current value of the generator and a tripping delay timing of
the protection device in tenths of a second.

KEYBOARD
HELP key – The illuminated LED means a help message is
available. By pressing the key, a help message concerning the
current operation is displayed.
ENTER and EXIT keys - Press ENTER to confirm operations
or to enter the menu. Press EXIT to refuse an operation or to
exit a menu and help message.
“⇓⇓
⇓⇓
⇓” and “⇑⇑
⇑⇑

different pages of data display or to select parameters.
“–” and “+” keys – Press these keys to display alternative
data of the selected data page or to modify the parameters.
OFF/RESET, MAN, AUT and TEST keys – Press these keys
to select the operating mode. The illuminated LED indicates
the selected operating mode; if it is flashing, remote control is
active.

START and STOP keys – These work in MAN operating
mode only, used to start and stop the engine. By quickly
pressing the START key, one start attempt takes place; by
keeping the START key pressed, the duration of the start
attempts can be extended. The flashing LED of the engine
symbol denotes engine started, with alarms inhibited; and is
constantly on at the end of the alarms inhibition time. The
engine can be stopped using the OFF/RESET key.
MAINS and GEN keys – They work in MAN operating mode
only, used to switch the load from mains to generator and vice
versa. The illuminated LEDs of the mains and generator
symbols indicate the respective voltages are within preset
limits. The illuminated LEDs of the changeover symbols indicate
the actual closing of switching devices; when flashing, there is
a incorrect feed-back signal for the actual closing or opening
of the switching devices.
OPERATING MODE
OFF/RESET mode – The engine can not operate. If the mains
is present, the load is switched to the mains. Changing from
TEST, AUT or MAN to the OFF/RESET mode and if the engine
is running, the engine is immediately stopped and eventual
alarms are reset. If the cause of the alarm is still present, it can
not be reset.
MAN mode – The engine can be manually started or stopped
using the START and STOP keys only in addition to load
switching from mains to generator and vice versa, by means of
the MAINS and GEN keys. Always in MAN mode, at the start
command and by keeping the key pressed, the preset starting
time can be prolonged while at the stop command and by
keeping the key pressed for more than 6 seconds, the fuel
valve is discharged for 4 minutes.
AUT mode – In case of mains not present (out of the preset
limits), the engine automatically starts or stops when the
mains returns.
TEST mode – The engine immediately starts even if the
mains is present. In case the mains is not present, the load is
switched to the generator. Changing to the AUT mode and if
the mains is present, the engine will stop.
Alarms
When an alarm arises, the lower section of the display is used
to view it. In case of two alarms or more, they are individually
shown in sequence. A help message is available for every
alarm, in order to locate the possible alarm source. Alarm
conditions can be reset by means of the OFF/RESET key, that
prevent any unintentional engine starting at the alarm reset
operation. If the alarm does not reset, this means the cause of
the alarm is still present. During event-log sessions and set-up
operations, no alarms are viewed.
