3Proprietary Information

The LogicsManagerTM permits the easYgen-3000 operating logic to be customized for each individual application. The status of discrete inputs, discrete outputs, internal conditions, alarms, and measured values may be combined into logical functions. These logical functions may be used to initiate numerous operational functions, such as starting the generator in the automatic mode.

Woodward’s LogicsManagerTM has been developed to give the user complete control for flexible configuration and operation.

• Direct Command value - The command value is

passed directly to the operator

• NOT Command value - The command value is inverted

passed to the operator

• Always "0"- The command value is ignored and

this logic path is always FALSE.

• Always "1"- The command value is ignored and

this logic path is always TRUE.
