DC ELECTRICAL SYSTEM
Safety Information
This circuit
is
designed and manufactured
in compliance with
united States Coast Guard Standards (33 CFR PART 183).
No modifica-
tions
may be made
to
it
by
the
installer or
user.
It is the
installer's responsibility to assure that the installation of the
generator set and any remote start panels or remote instrument panels
are installed in compliance with the above Coast Guard Standards.
Failure to observe these requirements could be the cause of injury.
Circuit Description
The two pole ON switch is operated to bypass the protective shut-
down switches during starting.
The second pole provides a source of·
B+ to the start toggle switch.
While continuing to hold the ON switch to provide B+ to the start
switch and
to bypass
the protective shutdown switches,
the start
switch is operated to cause the starter to crank the
engin~.
If
starting at the generator set,
release the start switch when the
generator is running.
If starting at a remote location, release the
start switch when the green LED shines.
Continue depressing the ON switch.
It is only necessary to con-
tinue holding the ON switch after releasing the start switch until oil
pressure is sufficient to close the oil pressure safety switch, pro-
viding the normal B+ path to the ignition system.
Note that it is now
impossible to energize the starter while the generator is running
until one again operates the ON switch first.
While operating, the overspeed shutdown module monitors engine RPM
and
will
ground
the
ignition system if
it senses engine RPM at
approximately 2175 RPM.
Should the generator shut down from an overspeed condition, the
overspeed cir.cuit MUST be reset before attempting to restart the
generator.
This is done by simply depressing the STOP switch momen-
tarily and then proceeding with the normal starting procedure.
SAFETY WARNING:
It is very important that the overspeed shut-
down always be installed and functioning.
Any tam-
per ing with the overspeed shutdown module, which
would cause it to malfunction, could be a cause of
injury should the generator belt-driven governor
fail and cause the generator to ft run awayft.
