GA-3.6RZ3 Instrumentation, Power Outlets

CAUTION :

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

Power Outlets

The generator has the following 120/240 volt 60 Hz (single- phase) receptacles.

zSingle Phase

One Duplex NEMA (GFCI) 5-20R (120V, 20 Amp) One Twist Lock NEMA L5-30R (120V, 30 Amp)

One Twist Lock NEMA L6-20R (240V, 20 Amp)

Main Circuit Breaker (2-Pole 120/240V 60 Hz)

This 2-pole 13.5 amp breaker protects the generator from short circuiting or overloading from the 120/240V 60 Hz single phase load.

Idle Control Switch

This unit is provided with an automatic idle control 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.

Fuel Gauge

The fuel gauge is located on the fuel tank and allows easy monitoring of the fuel level.

ACVoltmeter

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 generator or power tools turn the generator OFF and consult your authorized Multiquip service dealer.

Operation Switch

This switch must be in the ON position (up) for normal operation.

Start Switch

Push this switch to start the engine (electric start only). If a recoil starter is used, pull the starter rope to start the engine. Make sure the operation switch is in the ON position (up), otherwise engine will not start.

Full Power Switch

The unit is provided with a full power switch. Figures 2 and 3 show simplified wiring diagrams of the dual voltage system.

When the full power switch is in the 120 volt (up) position, you can take up full rated power of the generator at 120 volts from the single duplex receptacle, single locking type 120 volt receptacle, or a combination of these receptacles as long as the total load does not exceed the generating set capacity.

Figure 2. 120 V Simplified Diagram (Switch Up)

NOTE

When the full power switch is in the 120 volt position, the locking type 240 volt receptacle cannot be used.

When the full power switch is in the 240 volt (down) position, you can take up to half of the rated power of the generating set at 120 volts from the duplex receptacle and up to half of the rated power of the set at 120 volts from the locking type 120 volt receptacle; or full rated power of the set at 240 volts from the locking type 240 volt receptacle.
