malfunction or power distribution malfunction.
Please press down the emergency stop on the
control panel, so that to immediately shut down the
generator set. Under normal condition, please do not
use emergency stop to stop the generator set.
3.2.6
Normal stop the generator set
Before stop the generator set under normal
condition, first separate the load from this generator
set, then run the generator set with no load for a
certain period of time(3 to 5 minutes), so that to
make sure the generator set become fully cooled,
after that the generator set can be stopped. (Please
do not make cooling running under idle speed)
For some generator sets which have been installed
with stop solenoid, it is impossible to stop the
generator set by cutting off the key switch on the
control panel. Correct operation is: to press the stop
button when the power of the control panel being
resumed, only in this way you can stop the generator
set.(press the stop button until the generator set
fully stop running)
3.3
After Running
After the generator set stop running, it is necessary
to carry on following jobs:
◆To check if the generator set has “three leakage”
(lubricant, fuel, anti‐freeze leakage)
◆Shut down fuel valve
◆Shut down air inlet and air exhaust facility in the
generator set’s working room(when necessary)
◆Shut down the generator set’s output air switch
◆Shut down the power key switch on the control panel,
take out the key and keep it in good condition (when
necessary)
When the generator set need to be shut down for a
long time or is under maintenance, please dis‐connect
the start battery’s negative polar cable, and fully
discharge the fuel and anti‐freeze liquid when
necessary.
For the self‐start generator set, some of the above
terms are not applicable. After the self‐start
generator set stops, please keep it in the same status
as that of pre‐start (ready to start), so that it can start
at any time under emergency cases.
3.4
Record for running
For each running operation, user shall make record.
Running record has various forms. The basic content
shall cover: the time period for this running,
accumulated running time for this generator set,
value of engine’s oil pressure gauge, temperature
meter, output voltage, frequency, maximum
power(current) etc. and the running situation, and if
there is any malfunction warning / generator set shut
down etc.
Only when the correct and complete record for
running (maintenance) has been kept very well, the
user can get correct and excellent after sales
(warranty) service.
3.5
Matters need attention
Warning:
! When engine’s temperature is very low, the time
period for idle speed shall be properly extended.
However, when the generator set become warm, it is
not allowed to run the generator set with idle speed
for a long time, it is not allowed to continuously run
the generator set under empty or small load. Such
kind of operation will cause server carbon deposition
and oil leakage in engine’s turbo‐charger and
exhaust system.
! It is not allowed to run the generator set with
overload in long time period, otherwise malfunction
will occur, which will decrease the generator set’s life
expectancy.
! It is forbidden to detach or change the components
of the generator set when it is running.
! The coolant which is going to be added need to be
the same specification as that of the original cooling
system. When open the cover of water adding hole,
please pay attention to the temperature and avoid
the steam or high temperature coolant burst forth to
hurt people.
! When discharge the high temperature lubricant oil,
please avoid being burnt.
! The fuel being used shall be conform to national
standard, otherwise it will cause malfunction of the
engine’s fuel pump or fuel injector.
! For the engines installed with turbo‐charger, it is
suggested not to add 50% or above instant load to
the generator set. Otherwise this will cause relatively
big stall to the generator set.
! For the large electricity consumption equipment, it is
suggested that the users need to use methods such
as voltage decrease and frequency change etc. to
control the start, so that to reduce big impact on the
generator set when the facility start.
! Backup generator sets or the generator sets which
haven’t been run for a long time, it is suggested that
these kinds of generator sets shall be run to working
temperature at least one time a month. These kinds
of generator sets need to be continuously run with
full load for 4 hours at least one time per year.
! For the generator sets which are connected in
parallel and controlled by manual, operators must
make sure they are running synchronously(same
frequency, same phase‐sequence, same phase, and
same voltage) before switch on, and must switch off
before trying to stop the generator sets group.
