40kW Liquid-cooled Generators

1.6GENERATOR FUEL SYSTEM

The unit has been factory tested and adjusted using a natural gas fuel system. If propane (LP) gas is nec- essary, refer to "Reconfiguring the Fuel System" for conversion instructions.

Fuel pressure for a natural gas set up should be five inches to 14 inches of water column (0.18 to 0.5 psi) at all load ranges.

Fuel pressure for an LP vapor set up should be 11 inches to 14 inches of water column (0.4 to 0.5 psi) at all load ranges.

NOTE:

‹1.7.1 LOW OIL PRESSURE SWITCH

This switch is normally-closed (N.C.) but is held open by engine oil pressure during engine running. Should operating oil pressure drop below about 8-10 psi (55- 68 kPa), the switch contacts close, the engine shuts down automatically, and the low oil pressure LED is turned ON (Figure 1.4).

NOTE:

The Low Oil Pressure, High Coolant Temperature and Low Coolant Level are not monitored for the first 10 seconds of engine run time.

A seperate gas line and regulator may be needed

to assure proper gas pressure to the generator.

 

Improper gas pressure can cause hard starting and

 

affect engine durability.

 

Gaseous fuels such as natural and LP (propane)

gas are highly explosive. Even the slightest spark can ignite such fuels and cause an explo- sion. No leakage of fuel is permitted. Natural gas, which is lighter than air, tends to collect in high areas. LP gas is heavier than air and tends to settle in low areas.

1.7ENGINE PROTECTIVE DEVICES

The engine has several safety switches which cause the engine to automatically shut down under the following conditions: low oil pressure, high coolant temperature, engine overspeed, low coolant level or overcrank (Figure 1.3).

Temperature Switch

‹1.7.2 HIGH COOLANT TEMPERATURE SWITCH

This normally open (N.O.) thermostatic switch has sensing tip which is immersed in captive coolant. Should coolant temperature exceed about 230°F (110°C), the switch contacts close. This causes the engine to shut down automatically and turns on the high coolant temperature/low coolant level LED (Figure 1.5).
