OF
SWITCHES
This
manually
controlled series of WES1ERBEKE marine
diesel generators
is
equipped
wi1h
toggle switches
on
1he
engine control
panel
and,
optionally,
at remote panels.
All three
switches
are momentary contact type
and
serve
1he
following
functions:
PREHEAT:
The
PREHEAT
toggle
serves
two
purposes:
preheating
the
engine for
easy
starting and bypassing the
engine oil pressure switch. The
PREHEAT
function closes
the
K2
relay.

START:
The
START
toggle

closes
the
Kl
relay that
energizes the starter solenoid
and
activates the
starter.
While the
PREHEAT
switch
is
still depressed, depressing the
START
switch engages
the
start solenoid. When the engine
begins
to
fire,
the
START
switch should be released. The
PREHEAT
switch should not be released until
the
oil
pressure reaches 5 -
10
psi.
STOP:
The
STOP
toggle
switch
is
a normally closed switch
providing
power
to
the
K2
relay.
Opening of
this
switch
opens
the
power circuit to
the
fuel
solenoid, stopping the
flow
of
fuel
to
the
engine
and
shuts
down
1he
engine.
To
stop
1he
engine, depress
1he
STOP
switch.
When the
STOP switch
is
depressed,
the

opened,
and
the
fuel
flow
to
the engine
is
stopped.
The
STOP
switch
should be depressed until the generator
stops rotating
NOTE:
When
the
engine
is
shut
down,
the
water temperature
gauge
and
the
oil pressure
gauge
will continue
to
register
the
last temperature
and
oil
pressure
readings
displayed.
They
will
return
to
zero
once electrical power is
restored.
EMERGENCY
STOP:
The
EMERGENCY
stop switch
on
1he
side
of
the
control
box,
is
normally
closed.
When
depressed,
it
will
open
the
DC
circuit
to
the
control
panel
and
shut the
engine
down.
As
the
switch is not
toggled
it
can
be
used
when
performing
maintenance.

REMOTE
PANEL
For remote
operation
of
the
generator
system,
the
same
three
switches
are
used.
The
PREHEAT
and
START
switches
are
connected
in
parallel
with
the
gauge panel's
switches
and
serve
the
same
functions
as
in
the
gauge
panel.
The
STOP
switch
is
in
series
wi1h
the
gauge
panel's
STOP
switch
and
serves
the
same
function.
