Section 2 – Operation

2.6 STOPPING THE GENERATOR

1.Turn OFF all electrical loads using the means provided (such as a main circuit breaker or transfer switch).

2.Let generator run at no-load for a few minutes, to stabilize internal engine generator temperatures.

3.Place the Start/Stop switch in its STOP position.

2.7 APPLYING LOADS TO GENERATOR

Recreational Vehicle Generator

•Induction type motors (such as those that run the vehicle’s furnace fan, refrigerator, air conditioner, etc.) need about 2-1/2 time more watts of power for starting than for running (for a few seconds dur- ing motor starting). Be sure to allow for this when connecting electrical loads to the generator. First, figure the watts needed to start electric motors in the system. To that figure, add the running watt- ages of other items that will be operated by the generator.

When applying electrical loads to the generator,

• Do not apply heavy electrical loads for the first two

observe these guidelines:

or three hours of operation.

•Before applying electrical loads, let the generator stabilize and warm up for a minute or two.

•DO NOT overload the generator.

‹2.7.1 LETTING THE ENGINE STABILIZE

The generator supplies correct rated voltage only at the proper governed speed. Some electrical appli- ances may be extremely sensitive to voltage. Incorrect voltages can damage such appliances.

If electrical loads are applied at reduced operating speeds, such loads imposed on the engine when suf- ficient power is not available may shorten engine life. Never turn ON electrical loads until after the generator engine has started and stabilized at no-load.

2.8 DO NOT OVERLOAD THE GENERATOR

2.9 PROTECTION SYSTEMS

‹2.9.1 LOW OIL PRESSURE SWITCH

This switch (Figure 2.2) has normally closed (N.C.) contacts that are held open by engine oil pressure dur- ing cranking and operating. Should oil pressure drop below a preset level, switch contacts close, and the engine automatically shuts down. The unit should not be restarted until oil is added.

‹2.9.2 HIGH TEMPERATURE SWITCH

This switch (Figure 2.2), which has normally open (N.O.) contacts, is mounted near the oil filter. The contacts close if the temperature should exceed approximately 305º F (152º C), initiating an engine shutdown.

Read the rated wattage/amperage capacity of the generator on the generator data label (see "Generator Identification").

Figure 2.2 – Low Oil Pressure and

High Temperature Switches

High Temperature Switch

Applying electrical loads in excess of the unit’s rated capacity will cause the engine/generator to automati- cally shut down.

To avoid overloading, add up the wattage of all con- nected electrical lighting, appliance, tool and motor loads. This total should not be greater than the generator’s rated wattage capacity.

•Most lighting, appliance, tool and motor loads indicate their required watts on their nameplate or data plate. For light bulbs, simply note the wattage rating of the bulb.

•If a load does not show its rated wattage, multiply that load’s rated VOLTS times AMPS to obtain

WATTS.
