running

 

operation,

 

user

 

shall

 

make

 

record.

 

Running

 

record

 

has

 

various

 

forms.

 

The

 

basic

 

content

 

shall

 

cover:

 

the

 

time

 

period

 

for

 

this

Only

 

when

 

the

 

correct

for

 

running

 

(maintenance)

 

has

 

been

 

kept

 

very

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.
