GA-6H/GA-6HA — GENERAL INFORMATION

WARNING

Before connecting this generators 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-6H/GA-6HA FAMILIARIZATION

Generator

The Multiquip GA-6H and GA-6HA generators have been 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.

These generators are 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 generators to protect against damage. See Figures 3A through 3E for the basic controls and indicators for the GA-

6H/GA-6HA generators.

These portable generators are 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 is provided with the following:

■120/240V twist-lock output receptacle (single phase).

■120V twist-lock receptacle (2) (single phase).

■120V GFCI single phase duplex output receptacle (GA6HA has two).

■21 amp main circuit breaker.

■AC Voltmeter

■Ground Terminal

■Full Power Switch

■Idle Control Switch

■Operation Switch

Excitation System

The GA-6H/GA-6HA-series generators use a magnet attached to a flywheel to produce AC voltage from a lamp coil beneath the flywheel. As the magnetic 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.

Alternator

The alternator, a brushless revolving-field type, is permanently aligned to the engine through rigid coupling.

Engine

These generators are powered by a 11 HP, air-cooled, 4- stroke HONDA gasoline engine. Reference Table 2, for engine specifications.

GA-6H/GA-6HA A.C. GENERATORS — OPERATION & PARTS MANUAL — REV. #0 (06/02/05) — PAGE 15

GA-6H/GA-6HA — LOAD APPLICATION

Single Phase Load — 60 Hz

Always be sure to check the nameplate on the generators and equipment to insure the wattage, amperage and frequency requirements are satisfactorily supplied by the generators for operating the equipment.

Generally, the wattage listed on the nameplate of the equipment is its rated output. Equipment may require 130— 150% more wattage than the rating on the nameplate, as the wattage is influenced by the efficiency, power factor and starting system of the equipment.

If wattage is not given on the equipment's name plate, approximate wattage may be determined by multiplying nameplate voltage by the nameplate amperage.

WATTS = VOLTAGE x AMPERAGE

The power factor of this generators is 1.0 See Table 3 below when connecting loads.

Table 3. Power Factor By Load

	Type Of Load	Power Factor
	Single-phase induction motors	0.4 - 0.75
	Electric heaters, incandescent	1.0
	lamps
	Fluorescent lamps, mecury	0.4 - 0.9
	lamps
	Electronic devices,	1.0
	communication equipment
	Common power tools	0.8

When using a combination of dual receptacles, total load should not exceed the rated capacity of the generator.

To determine the running wattage for your load, multiply the running wattage as indicated by steps 1, 2, and 3 below:

1.INCANDESCENT LOADS

Lights, heaters and similar appliances. Total the running wattage and multiply by 1. Example:

29 light bulbs @ 100W each = 2.9 KW use a 3 KW generator.

2.SMALL MOTORS

Drills and other small power tools.

Total the running wattage and multiply by 2. Example:

A 1 inch drill runs at 1 KW use a 2 KW generator.

3.LARGE MOTORS

Submersible pumps, table saws etc.

Total the running wattage and multiply by 3. Example:

A conveyor belt runs at 8 KW use a 24 KW generator.

CAUTION

Motors and motor-driven equipment draw much greater current for starting than during operation. Always use an adequate size extension cable which can carry the required load.

Extension Cables

When electric power is to be provided to various tools or loads at some distance from the generator, extension cords are normally used. Cables should be sized to allow for distance in length and amperage so that the voltage drop between the generators and point of use (load) is held to a minimum. Use the cable selection chart (Tables

4 and 5 ) as a guide for selecting proper cable size.

The idle control device is operated at a minimum load capacity of 100W. If the load capacity is less than 100W, place the idle control switch in the OFF position.

	when lifting of the generators is required. Never stand
	underneath the generators while it is being lifted. Place
	lifting eye in down position when not in use.
2.	AC-Voltmeter – This voltmeter indicates (with a mark) the
	rated 60 Hz (single-phase) output voltage. In addition the
	voltmeter can also be used as a diagnostic tool. If the
	voltmeter indicator (needle) is below the rated voltage,
	engine problems may exist (low/high RPM's). To prevent
	damage to the generators or power tools turn the generators
	OFF and consult your authorized Multiquip service dealer.
3.	Idle Control Switch – The generators are provided with
	an automatic idle control device for noise suppression and
	reduced fuel consumption. The automatic idle control
	automatically engages under a no-load condition. With the

automatic idle control switched “ON”, the engine revolutions will automatically drop to about 2600 rpm (low-speed operation) within 3 seconds after the load stops. When the operation is resumed, the engine speed is automatically increased to about 3600 rpm (high-speed operation) as soon as the load is connected.

5.GFCIDuplexReceptacle– NEMA 5-20R, GFCI receptacle will provide 120V, 20 amps. (GA-6HA has two.)

Outdoor Installation

Install the generator/welder in a area that is free of debris, bystanders, and overhead obstructions. Make sure the generators is on secure level ground so that it cannot slide or shift around. Also install the generators in a manner so that the exhaust will not be discharged in the direction of nearby homes.

The installation site must be relatively free from moisture and dust. All electrical equipment should be protected from excessive moisture. Failure to do will result in deterioration of the insulation and will result in short circuits and grounding.

Foreign materials such as dust, sand, lint and abrasive materials have a tendency to cause excessive wear to engine and alternator parts.

CAUTION

Pay close attention to ventilation when operating the generators inside tunnels and caves.The engine exhaust contains noxious elements.

Mounting

The generators should always be mounted on a flat level surface to isolate vibration of the generators when it is running. DO NOT place the generators on slopes, the possibility exists that the generators could slide.

CAUTION

An electric shock is apt to happen when vibrators are used. Pay close attention to handling when operating vibrators and always use rubber boots and gloves to insulate the body from a short circuit.

GA-6H/GA-6HA — INSTALLATION

Indoor Installation

Exhaust gases from gasoline engines are extremely poisonous. Whenever an engine is installed indoors the exhaust fumes must be vented to the outside. The engine should be installed at least two feet from any outside wall. Using an exhaust pipe which is too long or too small can cause excessive back pressure which will cause the engine to heat excessively and possibly burn the valves.

Eliminate the danger of deadly carbon monoxide gas.

Remember that exhaust fumes from any gasoline engine are very poisonous if discharged in a closed room, but harmless if allowed to mix with the outside air. If the generators is installed indoors, you must make provisions for venting the engine exhaust to the outside of the building.

Generators Grounding

To guard against electrical shock and possible damage to the equipment, it is important to provide a good EARTH ground. Always use the ground terminal on the generators to ground the generator. Ground the generators from its ground connector so that the resistance to ground is 500 ohms or less.

Article 250 (Grounding) of the National Electrical Code (NEC) provides guide lines for proper grounding and specifies that the cable ground shall be connected to the grounding system of the building as close to the point of cable entry as practical.

NEC articles 250-64(b) and 250-66 set the following grounding requirements:

1.Use one of the following wire types to connect the generators to earth ground.

a.Copper - 10 AWG (5.3 mm2) or larger.

b.Aluminum - 8 AWG (8.4 mm2) or larger.

2.When grounding the generators (Figure 3) connect the ground cable between the lock washer and the nut on the generators and tighten the nut fully. Connect the other end of the ground cable to earth ground.

3.NEC article 250-52(c) specifies that the earth ground rod should be buried a minimum of 8 ft. into the ground.

GA-6H/GA-6HA — INSTALLATION

Connecting the Ground

The nut and ground terminal on the generators should always be used to connect the generators to a suitable ground.The ground cable should be #8 size wire minimum.

At the generator, connect the terminal of the ground cable between the lock washer and the nut (Figure 5) and tighten the nut fully. Connect the other end of the ground cable to a suitable earth ground (ground rod).

GA-6H/GA-6HA — PRE-INSPECTION

General Inspection Prior to Operation

Ground Power Tools

When using power tools or electrical equipment requireing AC power from the generator, make sure connecting (power tool) cable (Figure 6) has a ground as shown in Figure.

Figure 6. Ground Cables/Plugs

Extension Cable

When electric power is to be provided to various tools or loads at some distance from the generator, extension cords are normally used. Cables should be sized to allow for distance in length and amperage so that the voltage drop between the generators and point of use (load) is held to a minimum. Use the cable selection chart (Table 4) as a guide for selecting proper cable size.

Never! use power tools or equipment that do not have a ground capability, the possibility exists of electrocution, electrical shock or burn, which can cause severe bodily harm or even

DEATH!

Main Circuit Breaker

To protect the generators from an overload always place the main circuit breaker in the "OFF" position prior to starting the engine.

GA-6H/GA-6HA — INITIAL START-UP/GENERATOR OPERATION

6.If the engine has started, slowly return the choke lever (Figure 12 ) to the “OPEN” position. If the engine has not started repeat steps 1 through 5.

7.Before the generators is placed into operation, run the engine for 3-5 minutes. Check for abnormal smells, fuel leaks, and noises that would associate with lose components.

8.Place the idle control switch (Figure 15) in the "OFF" (down) position. This will allow the engine speed to run at speed about 3600 RPM's

Figure 15. Idle Control Switch (Off)

Placing the idle control switch in the OFF position (Figure 15) allows the engine to operate at a maximum speed of about 3600 RPM's. When the idle control switch is placed in the up position (ON) (Figure 16),

the generators will run at idle speed (2200 RPM's) until a load is applied, at that time the engine speed will increase to 3600 RPM's as long as the load is being applied. When the load is not in use, the engine speed will drop back to the idle mode after about 3 seconds.
