GA-6RZR2— GENERAL INFORMATION

WARNING:

Excitation System

Before connecting this generator to any building’s electrical system, a licensed electrician must install an isolation (transfer) switch.

Serious injury or death may result without this transfer switch.

GA-6RZR2 FAMILIARIZATION

Generator

The Multiquip Model GA-6RZR2 generator has been designed as a portable lightweight power source for 60 Hz (single- phase) vibrators, lighting facilities, power tools, submersible pumps and other industrial and construction machinery.

This generator is powered by a ROBIN gasoline engine. The alternator, a brushless revolving-field type, is permanently aligned to the engine through rigid coupling.

The generator is mounted on rubber vibration isolators that have a steel base backplate which is attached to the protective steel pipe carrying frame.The protective carrying frame is made of steel tubing and fully wraps around the generator to protect against damage.

This portable generator is supplied with a electrical control box. To reduce vibration caused by the engine, the control box is also placed on rubber isolators.

Control Box

The control box has the following: (all outputs are 60 Hz, single phase)

zOne 120V output receptacle.

zOne 240V output receptacle.

zOne 120V output receptacle (GFI protected).

zOne main 21 amp circuit breaker.

zAC Voltmeter

zIdle Control Switch

zFull Power Switch

zOperation Switch

All GA-series generators use a magnet attached to a flywheel to produce AC voltage from a lamp coil beneath the flywheel. As the magnet passes the coil it produces approximately 19-22 AC volts.

This voltage (19-22 VAC) is then sent to the control box that contains three rectifying diodes:

zExcitation (diode 1)

zBattery (diode 2)

zSlow Down (diode 3)

The AC voltage will pass through the excitation diode that converts the voltage to DC power.

This DC power is then sent to the excitation windings housed within the main windings commonly called the "stator".

This voltage is then transferred into the rotor through induction.The rotor contains two diodes within it which rectify the DC voltage and send it out through the main windings, as AC voltage.

Engine

The four-cycle air-cooled ROBIN gasoline engine is designed to meet every performance requirement of this generator. Reference Table 1, page 8 for engine specifications.

Figure 1 (page 10) shows the basic controls and indicators for the GA-6RZR2 generator.

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