10. STORAGE
Long term storage can have detrimental effects on both the engine
and alternator. These effects can be minimized by properly preparing
and storing the generating set.
10.1 ENGINE STORAGE
The engine should be put through an engine preservation
procedure that includes cleaning the engine and replacing all the
fluids with new or preserving fluids.
(See engine maintenance and operation manual)
10.2 ALTERNATOR STORAGE
When an alternator is in storage, moisture tends to condense in
the windings. To minimize condensation, store the generating set
in a dry storage area. If possible use space heaters to keep the
windings dry.
(See alternator maintenance and operation manual)
After removing the generating set from storage, perform an
insulation check.
10.3 BATTERY STORAGE
While the battery is stored, it should receive a refreshing charge
every 8 weeks up to a fully charged condition.
11. ENGINE JACKET WATER HEATER
Jacket water heater is used in order to startup the generating set
more easily and to take the load. In automatic generating sets,
jacket water heater is standard. In manual type generating sets it
is an option. Heater warms up the jacket water of the engine when
the generating set is not working.
12. GENERATING SET MAINTENANCE
A good maintenance program is the key to long generating set
life. The recommended maintenance program is provided on the
Periodic Maintenance Chart. This chart is given with all generating
sets.
Maintenance and service should only be carried out by qualified
technicians. The maintenance and service which are done must be
recorded to the Maintenance Record Form. In General, the generating
set should be kept clean. Do not permit liquids such as fuel or oil
film to accumulate on any internal or external surfaces. Wipe down
surfaces using an aqueous industrial cleaner.

3.GENERAL PRECAUTIONS AND CONTROLS WHICH MUST
BE DONE BEFORE STARTING UP THE GENERATING SET
Make a general visual inspection on the engine and alternator.
Check if there is any breakage, crack, indentation, leakage or
looseness. Never operate the generating set before removing
any fault, if any.
Take out foreign materials such as keys, tools, cleaning wool,
papers etc. on the engine and the alternator.
Check the engine oil level on the dip stick. Refill with an
appropriate oil if it is low. Oil level normally must be close to
the maximum level line.
Look at the water level by opeing the radiator tap. If it is
inadequate add more water. Water level must be 30 mm. lover
than the water filling neck.
Engine cooling water must include antifreeze according to the
coolest weather conditions in the area. A mixture of 50%
antifreeze and 50% water provides a good protection in all
area.
Inspect the radiator air outlet hood, open if clogged and clear
away all obstructions in front of the air outlet.
Check the air filter. Clean or replace the air filter, if
necessary.
Make sure that the generating set can easily take air from te
environment.
Check the battery connection cables. Take care to tighten the
loosened battery terminals with spanner and, cover with special
substance and keep clean in order to avoid oxidation.
Make sure that the emergency stop button is not pressed.
14.
To control and monitor the generating set, an electronic control
system has been used.
P 72 model control system is fitted from 10 kVA to
200 kVA. Control panel provides a means of
starting and stopping the generating set, monitoring its
operation and output and automatically shutting down
the set in the event of critical condition arising such as
low oil pressure or high engine temperature.
