Operator`s manual

If the specified (19° BID C) injection timing can-
not be attained, adjust the timing by increasing
or decreasing the thickness
of the injection pump
mounting shim. Changing the shim thickness by
0.004 inch (O.Olmm) changes the injection timing
by approximately one degree. To advance the
timing, decrease the shim !hichness, as required.
To retard the timing, increase the shim thickness,
as required.

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
adjustment may also be required in conjunction with the engine's speed adjustment.
II CAUTION II
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 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:
1. Connect the AC output leads to the AC terminal block in accordance with the AC Voltage
Connections diagram specified for your generator set, which appears in the "BT GENERA TOR" section
ofthis manual.
