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.
COLD WEATHER KIT For cold climates, optional cold weather kit (part number 0F6148) is recommended. The kit includes: • Battery Warmer • 4” Junction Box with hardware • 6 qt. pack 5W-30 synthetic oil (engine) RECONFIGURING THE FUEL SYSTEM NOTE: All models are configured for natural gas or LP vapor from the factory.
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 .
ENGINE COOLANT Check coolant level in coolant recovery bottle. See the “Specifications” section. • Add recommended coolant mixture as necessary. • Periodically remove radiator pressure cap to make sure the coolant recovery system is functioning properly. Coolant should be at bottom of radiator filler neck.
7. Start engine and check for oil leaks. Figure 10.2 - Oil Filter Oil Filter CHANGING THE ENGINE AIR CLEANER To replace the engine air cleaner, (part number 0A4637), remove the air cleaner cover and replace the air filter making sure it is positioned properly before reattaching the cover.
BATTERY MAINTENANCE The battery should be inspected per the “Service Schedule” section. The following procedure should be followed for inspection: 1. Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary. 2. Check the battery fluid level of unsealed batteries and, if necessary, fill with DISTILLED WATER ONLY.
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.
