bThis band is meant as guidaice to avoid routine overloading of the engine.
Loads in excess of this band for special testing, under direct monitoring by the manufacturer or system engineer, or momentary variations due to changing bus loads shall not invalidate the test.
cif Surveillance Requirement 4.9.A.1.2.f.6 is not satisfactorily completed, it is not necessary to repeat the preceding 24-hour test.
Instead, the diesel generator may be operated at 2400-2600 kW for 1-hour or until operating temperature has stabilized prior tc
