Section 1 – General Information
Standby Generator Set
1.3.6 OVERCRANK SHUTDOWN
After a prespecified duration of cranking, this func-
tion ends the cranking if the engine has failed to
start.
1.3.7 RPM SENSOR LOSS SHUTDOWN
If the speed signal to the control panel is lost, engine
shutdown will occur.
1.4 DC FUSES
These fuses are located inside the control panel. They
protect the panel wiring and components from dam-
aging overload. The unit will not start or crank if a
fuse is blown. Replace the fuses with the same size,
type, and rating.
1.5 FUEL SYSTEM
1.5.1 FUEL REQUIREMENTS
NOTE:
It is the responsibility of the installer to make sure
that only the correct recommended fuel is sup-
plied to the generator fuel system. Thereafter, the
owner/operator must make certain that only the
proper fuel is supplied.
For further information on the various types of
fuel systems, refer to Engine-Generator Standby
Electric Power Systems Installer’s Guide and
Reference Manual (part #046622).
1.5.2 DIESEL FUEL SYSTEM
Diesel fuel is supplied to the generator set from a
base-mounted fuel tank.
Diesel fuels are less volatile than gaseous fuels, how-
ever, careless installation can lead to safety hazards
and/or serious problems with engine/generator per-
formance and reliability.
NOTE:
Appropriate care should be taken in applications
where extremely low ambient temperatures are
possible to ensure the temperature of the diesel
fuel is not allowed to fall below levels where “gell-
ing” could occur.
