Adjustments (Generator)
Once the diesel generator set has been placed in operation, there is
no
adjustment required
by
the AC gen-
erator. The
only adjustment that would be required is the speed adjustment made
to
the linkage between
the
fuel solenoid and the throttle arm in the event of a change
of
operating frequency between 50 and 60
Hertz. This adjustment is given below.
CAUTION
When starting the generator, it is recommended that all AC loads, especially large motors, be
switched
OFF until the engine has come up
to
speed and, in cold climates, starts
to
warm up.
This precaution will prevent damage caused
by
the unanticipated operation
of
AC machinery
and will prevent a
cold engine from stalling.
Generator Frequency Adjustment
Frequency is a direct
result of engine/generator speed, as indicated
by
the following:
When the generator is run at 1800 rpm, the AC voltage output frequency is 60 Hertz. When the generator
is run at
1500 rpm, the AC voltage output frequency is 50 Hertz.
Therefore,
to
change
the
generator's frequency, the generator's speed must be changed.
To
accomplish
the frequency change, perform the following:
Connect the AC output leads
to
the AC terminal block in accordance with the AC Voltage Con-
nections diagram which appears in the
"ST GENERATOR" section
of
this manual, page
37.
