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 (singlephase) 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.

Outdoor Installation
GLW-180H — INSTALLATION
CAUTION :
Install the generator in a location where it will not be exposed to rain or sunshine. Make sure that the generator is on secure level ground so that it cannot slide or shift around. Also install the generator 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, not only to the engine parts, but also to the alternator parts.
CAUTION :
Pay close attention to ventilation when operating the generator inside confined areas. The engine exhaust contains noxious elements.
Indoor Installation
Exhaust GLWses from GLWsoline 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 GLWs. Remember that exhaust fumes from any GLWsoline engine are very poisonous if discharged in a closed room, but harmless if allowed to mix with the outside air.If the generator is installed indoors, you must make provisions for venting the engine exhaust to the outside of the building.
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.
Generator Grounding
To guard aGLWnist electrical shock and possible damage to the equipment, it is important to provide a good EARTH ground.
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 (Figure 3) as close to the point of cable entry as practical.
NEC articles 250-91a and 250-95 set the following grounding requirements:
1.Use one of the following wire types to connect the generator 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 generator (Figure 3) connect the ground cable between the lock washer and the nut on the generator and tighten the nut fully.Connect the other end of the ground cable to earth ground.
3.NEC article 250-83c specifies that the earth ground rod should be buried a minimum of 8 ft. into the ground.
NOTE
When connecting the generator to any buildings electrical system ALWAYS consult with a licensed electrician.

General Inspection Prior to Operation |
Circuit Breaker |
This generator has been thoroughly inspected and accepted prior to shipment from the factory.However, be sure to check for damaged parts or components, or loose nuts and bolts, which could have occurred in transit.
To protect the generator from an overload, a single-pole 40 amp circuit breaker is provided on the control box. Make sure to switch this circuit breaker to the "OFF" position prior to starting the engine.
Ground
The nut and ground terminal on the generator should always be used to connect the generator to a suitable ground. The ground path should be of #8 size wire.
Connect the terminal of the ground wire between the lock washer and the nut at the base of the generator and tighten the nut fully. Connect the other end of the ground wire to a grounding rod as shown in Figure 3.
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 generator and point of use (load) is held to a minimum. Use the cable selection chart (Table 2 ) as a guide for selecting the proper extension cable size.

Fuel
Close the fuel cock before filling the tank. Fill the fuel tank with clean and fresh unleaded GLWsoline. DO NOT fill the tank beyond capacity.
Pay attention to the fuel tank capacity when replenishing fuel. Refer to the fuel tank capacity listed on page 8 Specification Table 1.
The fuel tank cap must be closed tightly after filling.
Handle fuel in a safety container. If the container does not have a spout, use a funnel.
CAUTION :
Never fill the fuel tank while the engine is running or in the dark. GLWsoline spillage on a hot engine can cause a fire or explosion. If GLWsoline spillage occurs, wipe up the spilled GLWsoline completely to prevent fire hazards.

Single Phase Load
Always be sure to check the nameplate on the generator and equipment to insure the wattage, amperage and frequency requirements are satisfactorily supplied by the generator 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.
NOTE
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
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.
GLW-180H — LOAD APPLICATION
CAUTION:
Motors and motor-driven equipment draw much greater current for starting than during operation.
An inadequate size connecting cable which cannot carry the required load can cause a voltage drop which can burn out the appliance or tool and overheat the cable.
The idle control is operated at minimum load capacity of 100W. If the load capacity is less than 100W, throw the idle control switch to the OFF position.

GLW-180H — GENERATOR OPERATING INSTRUCTIONS
Before Starting
1.Be sure to disconnect the electrical load and switch the main circuit breaker to the “OFF” position prior to starting the engine.
2.Never start the engine with the main circuit breaker “ON”.
3.Check the lubricating oil level prior to starting the engine.
Make sure the generator is level. The oil level must be maintained between two notches on the dipstick.
4.When there is not enough lubricating oil, fill the crankcase with high grade motor oil. Use a high quality detergent oil classified SC, SD or SE. (See Table 3 on page 15)
CAUTION:
|
z NEVER start the engine when the oil level |
|
is below the lower mark on the dipstick. |
|
z Check the fuel level on the fuel GLWuge. |
|
When fuel is low, fill the fuel tank with |
|
clean fresh unleaded automotive |
|
GLWsoline. |
Starting |
z If GLWsoline spillage occurs, completely |
wipe up the spilled GLWsoline. |
1.Place the idle control switch in the “ON” (up) position.
2.Close the choke. Adjust the opening of the choke valve according to operating conditions. When the engine is warm or the air temperature is high, close the choke valve halfway or open it all the way.
3.Confirm that the main circuit breaker on the generator control box is “OFF”.
4.Set the operation switch to the “ON” position and grasp the starting rope and slowly pull it out. The resistance becomes hardest at a certain position, corresponding to the compression point. Rewind the rope a little from that point and pull out sharply.
5.If the engine fails to start, repeat the procedure.
CAUTION:
zDO NOT pull the starter rope all the way to the end.
zDO NOT release the starter rope after pulling. Allow it to rewind as soon as possible.
Warm up
1.When the engine starts, open the choke slowly.
2.Run the engine at low speed for 3 minutes without load until the engine warms up.
3.Turn the idle control switch to the "OFF" (down) position and check the voltage by referring to the voltmeter on the control box.
CAUTION:
DO NOT change the engine speed control lever which has been set at the factory prior to shipping.
1.Check the generator for abnormal noise and smells.Then connect the load to the receptacles of the generator.
2.Switch the main circuit breaker to the “ON” position and turn the idle control switch to the “ON” (down) position for normal (load) engine operation.
Operation
Check the voltage by referring to the voltmeter on the control box. When the voltmeter indicates 120 volts, 120 volts from the 120V receptacles and 240 volts from the 240V receptacle can be obtained at the same time. Refer to Figure 1, Controls and Indicators, item 4 on page 10.
Stopping the Engine
CAUTION:
NEVER stop the engine suddenly while running at high speeds.
1.Remove the load from the generator. Place the circuit breaker in the “OFF” position. Refer to Figure 1, item 5 on page 10. Run the engine (no-load) with the idle control switch set to the ON position for three to five minutes, then stop the engine.
2.Turn the START/STOP switch to the “STOP” position.
3.Never stop the engine suddenly while running at high speed.
4.Close the fuel cock.
