GLW-180H — 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.

GLW-180H FAMILIARIZATION

Generator/Welder

The Multiquip Model GLW-180H 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 HONDA GLWsoline 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 aGLWinst 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 120V output receptacle (GFCI protected).

zOne main 40 amp circuit breaker.

zAC Voltmeter

zIdle Control Switch

zOperation Switch

zOutput Terminals (Welding)

All GLW-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 HONDA GLWsoline 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 GLW-180H generator.

Idle Control Switch

DO NOT use the idle control switch in conjunction with AC electro-magnetic switches relays etc. Using the idle control switch with these devices will cause the idle control device not to actuate. If any of these devices are being used, leave the idle control switch in the OFF position.

When running capacitor start motors such as submersible pumps, the idle control switch should NOT BE USED. Disconnect the pump or tool from the power source by switching OFF the main circuit breaker.

NOTE

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