FULL POWER SELECTOR SWITCH

All models except 3W735B, 3WY47, and 3WY45 have a full power selector switch on the control panel. The switch has two positions: 120 VOLT ONLY, and 120/240 VOLT.

120 VOLT ONLY: This position sends full power to the 120V receptacles only. 240V power is not available. Use this position when powering 120V items only.

Figure 5 – Full Power Selector Switch in 120 Volt Only Position

120/240 VOLT: This position sends full power to the 120/240V receptacle. It also powers the 120V receptacles at reduced wattage capacity.

IMPORTANT: Do not move the full power selector switch while powering electrical items. Unplug all items before moving switch. Failure to do so can damage switch.

Models 3W735B, 3WY45, and 3WY47 do not have this switch. These models provide full power to all receptacles.

HOUR METER

All models except 3W735B have an hour meter. The hour meter is on the control panel. The hour meter shows the total generator run time, including all idle time (See Figure 7). Hour meter is accurate up to 1/10 of an hour.

AUTO-IDLE SYSTEM

The auto-idle system allows the engine to idle down or run at a slower speed when the generator is not being used to supply power. The auto-idle system can be turned ON or OFF by a rocker switch on the control panel. When the switch is in the OFF position, the engine runs at full speed all of the time. When the switch is in the ON position, the engine slows down to idle speed until an electrical load is applied. When a load is applied to the generator (an electrical item is plugged in and turned on) the engine speeds up to the preset speed required to produce the correct voltage.

IMPORTANT: A minimum current load of 1 Amp is required to disengage the auto idle solenoid and cause the engine to come up to speed for correct voltage.

Powering items at reduced engine speed will damage generator and powered items.

ELECTRIC START (MODELS 3WY46, 3WY45, AND 3WY47 ONLY)

Models 3WY46, 3WY45, and 3WY47 have an electric starter. A battery is not supplied with generator. You must provide a 12- volt, 32-amp-hour battery. For more battery information, see ÒBattery,Ó page 8.

GROUND FAULT CIRCUIT INTER- RUPTER RECEPTACLE

All models have a 120-volt ground fault circuit interrupter (GFCI) receptacle. The GFCI receptacle is on the control panel or top cover of alternator (Model 3W735B only). The GFCI protects you against hazardous electrical shock caused when your body becomes a path through which electricity travels to reach ground. This could happen when you touch an appli- ance or cord that is ÔliveÕ through faulty mechanism, damp or worn insulation, etc.

When protected by the GFCI, you may still feel a shock, but the GFCI should cut it off quickly. A person in normal health should not receive serious injury.

NOTE: Infants and very small children may still be affected.

TEST PROCEDURE

Check the GFCI receptacle every month. This insures it is working right.

1.Push black TEST button. Red RESET button should pop out. This should trip GFCI, resulting in no electrical power at receptacle. Verify this by plugging test lamp with good bulb into receptacle. If lamp does not work, GFCI receptacle is good.
