EQUIPMENT DESCRIPTION This equipment is a revolving field, alternating cur rent Stationar y Emergency Generator set. It is powered by a gaseous fueled engine operating at 1800 rpm for 4-pole direct drive units, 3600 rpm for 2-pole direct drive units and 2300 - 3000 rpm for quiet drive gear units. See the Specifications section for exact numbers. Th[...]

ENGINE PROTECTIVE DEVICES The Stationar y Emergency Generator may be required to operate for long periods of time without an operator on hand to monitor such engine conditions as coolant temperature, oil pressure or rpm. For that reason, the engine has several devices designed to protect it against potentially damaging conditions by automatically s[...]

FUEL SYSTEM FUEL REQUIREMENTS The Stationar y Emergency Generator may be equipped with one of the following fuel systems: • Natural gas fuel system • Propane vapor (LPV) fuel system Recommended fuels should have a Btu content of at least 1,000 Btu's per cubic foot for natural gas; or at least 2,520 Btu's per cubic foot for LP gas.
