Generator drive engines are not designed for and shall not be used in variable speed D.C. generator set applications. STANDBY POWER RATING Applicable for supplying emergency power for the duration of the utility power outage. No overload capability is available for this rating. Under no condition is an engine allowed to operate in parallel with the public utility at the Standby Power rating. This rating should be applied where reliable utility power is available. A Standby rated engine should be sized for a maximum of an 8% average load factor and s of operation per year. This includes less than 2 s per year at the Standby Power rating. Standby ratings should never be applied except in true emergency power outages. Negotiated power outages contracted with a utility company are not considered an emergency. PRIME POWER RATING Applicable for supplying electric power in lieu of commercially purchased power. Prime Power applications must be in the form of one of the following two categories: UNLIMITED TIME RUNNING PRIME POWER Prime Power is available for an unlimited number of s per year in a variable load application. Variable load should not exceed a 7% average of the Prime Power rating during any operating period of s. The total operating time at % Prime Power shall not exceed s per year. A % overload capability is available for a period of 1 within a 12- period of operation. Total operating time at the % overload power shall not exceed 2 s per year. LIMITED TIME RUNNING PRIME POWER Limited Time Prime Power is available for a limited number of s in a non-variable load application. It is intended for use in situations where power outages are contracted, such as in utility power curtailment. Engines may be operated in parallel to the public utility up to 7 s per year at power levels never to exceed the Prime Power rating. The customer should be aware, however, that the life of any engine will be reduced by this constant high load operation. Any operation exceeding 7 s per year at the Limited Time Prime Power rating should use the Continuous Power rating. CONTINUOUS POWER RATING Applicable for supplying utility power at a constant % load for an unlimited number of s per year. No overload capability is available for this rating. Data shown above represent gross engine performance capabilities obtained and corrected in accordance with ISO-46 conditions of kpa (29.3 in Hg) barometric pressure [1 m (361 ft) altitude], 2 C (77 F) air inlet temperature, and relative humidity of % with No. 2 diesel or a fuel corresponding to ASTM D2. See reverse side for application rating guidelines. The fuel consumption data is based on No. 2 diesel fuel weight at.8 kg/liter (7.1 lbs/u.s. gal). Power output curves are based on the engine operating with fuel system, water pump and lubricating oil pump; not included are battery charging alternator, fan, optional equipment and driven components.
