battery
and
the starting motor to avoid the voltage drop too
hard
when the engine
starting, the section
area
36mm2 low voltage connecting cable should
be
adopted.
When the staring current
is
highest, for
12V
and
24
V starting motor, the voltage
drop should
be
less than
o.
5V
and
1V respectively.
The
battery with the diesel engine hasnt been charged before delivery, it-should
be
first charged
as
the battery"s requirement before used. When the diesel engine
is
working, the amount of the charging current should often
be
noticed. When the
needle of the ammeter
is
reaching to zero, or shows that the battery
has
been fully
charged
and
the charging circuit
can
be
switched off.
The
diesel engine adopts the
JF
series siticon rectified dynamo which
has
the char-
acteristics of small volume, simple structure, low speed electrification etc.
The
use of voltage regulator
is
to keep the voltage at the range of 13.5
-14.
5V or
27
-29V
respectively when the speed of the
14V
or
28V
generators adopt
FTlll
or
FT211
voltage regulator respectively. If the charging' indicator
is
needed, the genera-
tors should adopt
FT126
or
FT226
voltage regulator. When the
FTlll
type
and
FT211
type regulators
are
used, the key switch should
be
turned off
as
soon
as
the engine
stops
in
case the battery discharge to the magnetic coil
and
make the battery insuffi-
cient, this will influence the next starting.
The
regulator
is
a precise instrument
and
not
be
dismantled
and
regulated at
will,
if
it
is
necessary to
be
adjusted, it should
be
done at special equipment.
The
starting motor
is
full closed direct current series excitation motor.
The
working
current of the starting motor
is
very larg'e, it
can
only works within a short
time,
and
every starting time can't exceeds lOs. if it"s necessary to continuously start, the
break shouldnt less than 2 minutes
and
shouldnt exceed
10
times
in
case the start-
ing motor
and
the battery
be
damaged.
The
key switch
has
three working positions, at the center position, the whole circuit
will
be
turned
off,
turning the key clockwise, the preheating - starting switch, Volt-
age
regulator
and
other electric equipment will
all
be
switched
on
and
the diesel
en-
gine
wiH
start. After the engine starts, the switch should
be
turned anticlockwise to
the end to turn off the preheating - starting switch
and
in
Case
of any trouble.
If the pre - heater
is
used, a preheating - starting switch should
be
adopted.
The
preheating - starting switch
has
four working positions. At
the"
Preheat
ll
position,
only the pre - heater or electric plunger will
be
turned on. At
the"
Preheat - start"
position, both the pre - heater
and
the starting motor will
be
turned
on.
At
the"
start" position, only starting motor will
be
turned
on.
To
loose the switch, it will
au-
tomatically moves back to
the"
0"
position
and
the whole circuit will
be
cut off.
