Adjustments (Generator)
Once the diesel generator set has been placed in operation, there may
be
adjustments required for engine
speed (Hertz) during the engine's break-in period (first 50 hours) or after this period. A no-load voltage ad-
justment may also be required in conjunction with the engine's speed adjustment.
CAUTION
When starting the generator, all AC loads, especially large motors, should be switched OFF
until the engine has come up to speed and, in cold climates, starts to warm up. This precau-
tion will prevent damage caused by unanticipated operation of AC machinery and will prevent
a cold engine from stalling.
Generator Frequency Adjustment (Hertz)
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 engine's speed must be changed. To accomplish the
frequency change, perform the following:
1. Connect the AC output leads to the AC terminal block in accordance with the AC Voltage Connections
diagram specified for your generator set, and change the Hertz connection to the capacitor. These con-
nections are illustrated in the "BC GENERATOR" section of this manual, page 54.
2. Adjust the engine's speed to obtain the frequency corresponding to the voltage selected by extending
or shortening the Throttle Adjustment Linkage. Make sure the solenoid's plunger is completely bot-
tomed in the solenoid. (See figure below.)
