INTRODUCTION Thank you for purchasing this model of the standby generator set product line. Every effort was expended to make sure that the information and instructions in this manual were both accurate and current at the time the manual was written.
ENGINE RPM ALTERNATOR SUBTRANSIENT REACTANCE ALTERNATOR TRANSIENT REACTANCE CLASS ROTOR GENERAC POWER SYSTEMS, INC. Standby Generator Sets General Information For actual information related to this particular model, please refer to the Manual Drawing Listing located at the end of this manual, or to the data label affixed to the unit.
EQUIPMENT DESCRIPTION This equipment is a revolving field, alternating cur- rent 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.
ENGINE PROTECTIVE DEVICES The standby generator may be required to operate for long periods of time without an operator on hand to monitor such engine conditions as coolant tempera- ture, oil pressure or rpm. For that reason, the engine has several devices designed to protect it against potentially damaging conditions by automatically shutting down the unit when the oil pressure is too low, the coolant temperature is too high, the coolant...
FUEL SYSTEM FUEL REQUIREMENTS The standby generator may be equipped with one of the following fuel systems: • Natural gas fuel system • Propane vapor (PV) fuel system The Manual Drawing Listing that is affixed to the unit includes the “Identification Code,” which may be used to identify the type of fuel system installed on the unit.

GENERATOR AC LEAD CONNECTIONS See “Voltage Codes”. This generator may be rated at any one of three voltages, either single-phase or three-phase. The electrical wires in the unit’s AC con- nection (lower) panel should be installed according to the number of leads and the voltage/phase required for the application.
INSTALLATION Refer to the separate “Installation Guide QT Product Line” supplied with the unit. PREPARATION BEFORE START-UP The instructions in this section assume that the standby generator has been properly installed, ser- viced, tested, adjusted and otherwise prepared for use by a competent, qualified installation contractor. Be sure to read the “Safety Rules”, as well as all other safety information in this manual, before attempting to operate this (and related) equipment.
START-UP CHECKLIST Before working on the generator, ensure the fol- lowing: • The AUTO/OFF/MANUAL switch is in the OFF position. • The 120VAC supply to the battery charger is switched OFF . PREPARATION FOR START-UP • Ensure that the 120VAC circuit breaker to the bat- tery charger is open.
GENERATOR CONTROL AND OPERATION Refer to the appropriate control panel operator’s manual for this unit. OPERATING UNIT WITH MANUAL TRANSFER SWITCH If the generator was installed in conjunction with a transfer switch capable of manual operation only, the following procedure applies. A manually operated transfer switch is one that will not provide automatic start-up and does not include an intelligence circuit.
MAINTENANCE PERFORMED BY AUTHORIZED SERVICE FACILITIES Before working on the generator, ensure the fol- lowing: • The AUTO/OFF/MANUAL switch is in the OFF position. • The 15A fuse has been removed from the con- trol box. • The 120VAC supply to the battery charger is switched OFF .
Figure 10.1 - Oil Dipstick and Oil Fill Cap Oil Fill Cap Dipstick BATTERY FLUID Check battery electrolyte fluid based on the Maintenance Schedule. Fluid should cover separa- tors in all battery cells. If fluid level is low, add dis- tilled water to cover tops of separators.
CHANGING ENGINE OIL Refer to maintenance performed by authorized service facilities for engine oil and filter change frequencies. Drain the oil while the engine is still warm from run- ning. This means warm up the engine, shut it down and drain immediately as follows: 1.
MISCELLANEOUS MAINTENANCE CLEANING THE GENERATOR Keep the generator as clean and as dry as possible. Dirt and moisture that accumulates on internal gen- erator windings have an adverse effect on insulation resistance. Periodically clean generator exterior surfaces. A soft brush may be used to loosen caked on dirt. Use a vacuum system or dry, low pressure air to remove any accumulations of dirt.
SERVICE SCHEDULE 30 KW - 150 KW STANDBY GAS ENGINE DRIVEN GENERATOR SETS The following is a recommended maintenance schedule for standby gas engine driven generator sets from 30kW to 150 kW in size. The established intervals in the schedule are the maximum recommended when the unit is used in an average service application.
