GENERAL INFORMATION

FAMILIARIZATION

Generator

The Multiquip DA7000 Series generators are 6.0 kW (continuous output), 7.0 kW (max output) A.C. generators designed as a portable dual purpose power source for 60 Hz (single phase) lighting facilities, power tools, submersible pumps and other industrial and construction machinery.

Control Panel

The control box is provided with the following:

GFCI 120 volt receptacle, 20 amp (single-phase)

120 volt receptacle, 25 amp (single-phase)

120/240 volt receptacle, 25 amp (single-phase)

120/240 volt receptacle, 25 amp (single-phase)

AC Voltmeter

Main Circuit Breaker 265V @25 Amps

GFCI Circuit Breaker 120V @20 Amps

Idle Control Switch

Starter Switch

Warning Lamp Unit

Hour Meter

Ground Terminal

Engine Protection System

Engine protection fail safe features are provided in the event of low oil pressure, high coolant temperature and failure of the battery to charge. If any of the above conditions occur while operating the generator it will cause a complete unit shut down.

Oil Pressure Warning Alarm

This unit is equipped with a protective device that detects low oil pressure. If the lubricating oil pressure of this unit should become abnormally low, the protective device will automatically stop the engine. If this condition should occur, please refer to the engine troubleshooting table in this manual.

Idle Control Switch

The DA7000 series generators are provided with an automatic idle (engine) control capability for noise suppression and fuel cost reduction. The automatic idle control feature automatically engages under a no-load condition.

With AC loads of more than 150W (such as lighting equipment, motor-powered tools, submersible water pumps, etc.), the engine runs at high speed.When a no load condition is produced, the engine automatically slows down.

Turn the idle control switch to the “ON” (up) position when AC loads of more than 150W are connected. Turn the idle control switch to the “OFF” (down) position when AC loads of less than 100W or when a magnetic switch is used.

Excitation System

The DA7000 series generators use a brushless exciter to create rated output electricity. This system will use the mechanical energy generated by the 3600 RPM engine to spin the rotor (or armature) inside the generator (or alternator end).

Excitation current is sourced from the battery to the excitation windinding in the stator. Current applied to this coil creates a magnetic fi eld. The rotating armature is induced with AC current.

Battery Charge Alarm

This unit is equipped with a protective device that signals an alarm and automatically stops the engine when the battery cannot be charged by the alternator.

Water Temperature Alarm

This unit is equipped with an apparatus that signals an alarm and automatically stops the engine when the cooling water temperature becomes abnormally high. This apparatus will not function properly if the machine is operated with less than the proper amount of coolant.

Engine

The DA7000 series generators are powered by a water- cooled, 4-cycle KUBOTA diesel engine. This engine is designed to meet every performance requirement of the generator. Reference Table 2, engine specifications.

In keeping with Multiquip's policy of constantly improving its products, the specifications quoted herein are subject to change without prior notice.

Figure 3 and Figure 4 show the basic controls and indicators for the DA7000 series generators.
