FREQUENCY
FAULT
Frequency
is
displayed·on the LCD display screen while the
engine
is
running
in
RPM and frequency (hertz).
The ECU
is
receiving a low AC voltage signal and hertz
signal from the
MPU which
is
positioned on the bellhousing
over the flywheel ring
gear teeth. The ECU interprets this
signal
as
both RPM and hertz.
· Should this signal vary approximately 2% either
up
or down,
a frequency fault shut down will occur, initiated
by
the ECU.
The red failure LED on the display panel will
illuminate,-the
frequency LED will turn from green
to
amber and the LCD
display screen will show the fault text
"overspeed".

1.
Tum
the
DC
breaker
on
the control panel to the
OFF
position.
2. Open the cover
of
the control box and view the
ECU
(Electronic Control Unit).
3.
Access the opening
of
the ECU.
The
dipswitches are
visable in the elongated area
of
this opening.
4. Access the #1 dipswitch and move it to the position
that corresponds to the hertz operation desired. The
illustration
shows these dipswitches.
5. Plug in the communications cable from your laptop
having the
EC20 software.
The
communications cable
plug connection should have the arrow
on
the plug facing
the
ECU
connections. Reprogram the
ECU
for the
corresponding
AC
voltage output the generator is being
changed to.
6. Once the change is completed,
tum
OFF
your laptop.
Unplug the communications cable from the ECU.
7. Proceed to page
39Aofthis
manual and follow the
procedures for reconfiguring the
AC
voltage output
of
the generator that has been selected.

CAUSED
BY
HEAT,
THIS
IS
NORMAL
AND
NO
CAUSE
FOR
CONCERN.
CAUTION
(WESTERLINK
or
NMEA-2000):
The electronic components
in
the Digital Diesels draw a vel)' small amount
of
amperage (milli-amps) froni the
generator's starting battery
whe.n
the
unit
is
in
a static state. This maybe as much as 50 milli-amps
for
the system ECU and 50 milli-amps for each display.
This can be as much
as
72
amp-hours
in
a months time with no generator use.
It
is not necessary
to
be concerned with this slight amperage draw during
normal seasonal use. However, if the generator set
is
not
ro
be used
for
a number
of
mollths, such as winter storage,
it
is best to disconnect the DC power
to
the generator with a NMEA-2000 system or shut
off
the DC breaker
on
the generator's control box for a WESTERLINK system.
NOTE:
Keep
in
mind that the Westerbeke generator maybe the DC power supply for the
vessel~·
NMEA-2000 network.
