START AND STOP AUTOMATIC VERSION
Manual start
•
Feed the electric board placing the selector SWITCH BOARD
in ON position.
•
Choose on te control unit GECO the working mode MAN.
If the control unit GECO is programmed for only manual
start the working modes TEST and AUTOMATIC are
disactivated.
•
Start the engine pressing the START key.
•
The engine starts at its works speed, check on the control
unit GECO that voltage and frequency values are right.
•
After starting let the engine run for a few minutes.
Make sure that there are no danger situations in the plant to
be fed.
•
Feed the loads connected placing the power divider POWER
in ON position.
Stop.
At the end of each working set:
•
disconnect the loads placing the power divider POWER in
OFF position;
•
Let the engine run loadless for e few minutes;
•
Press the key STOP on the control unit GECO;
•
Cut off feeding the electric board putting the selector
SWITCH BOARD in OFF position.
Automatic start
The generating set associated to the board of only
telecommutation PAC forms a system which supplies electric
energy in few seconds after the commercial mains fails.
Teh control unit GECO provides to substitute failing/presence
of mains and consequently starts or stops automatically the
generating set.
We give here below some general operative information.
•
Make safety the connections of the plant.
Position the control unit GECO in RESET.
•
Execute the first start in manual mode.
•
Position the unit control GECO in AUT mode.
•
The generating set is now ready for automatic start.
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.
