LogicsManager

2. Introduction
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.

3. Introduction Internal Conditions Digital Signals Relay Outputs
Conditions - CB status - operating mode - engine status
Alarms - warning alarm - shutdown alarm
Time / Date

8. Input command variables
Status Screen in HMI
The alarm class for discrete inputs, which are used as input commands, must be configured to „Control“

9. The sign defines when the input is enabled
Signs
The sign defines when the input is enabled
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.

10. Signs
Command input:
Grey if sign = TRUE or FALSE

11. Operators
Operator 01 and 02

12. Time Delay
Delay ON
is the amount of time that the logical output state is delayed before changing to true
Delay OFF
is the amount of time that the logical output state is delayed before changing to false
Delay ON
Delay OFF

13. Logical outputs Relay outputs Logical functions Internal flags
Any discrete output that is freely configurable
Logical functions
Internal functions and conditions such as “Start in Auto” and “Firing Speed reached”
Additional Boolean equations which can be used whenever three input commands are not enough or time delayed signals are required
Internal flags

14. Logical outputs Relay outputs Relay output 1 Ready for operation OFF
Relay 2 to 12 Depending on configuration
External relays via expansion board
can be used as additional flags if not utilized

15. Logical outputs
Internal flags

16. Logical outputs Logical functions Start request in AUTO
Stop request in AUTO
Load dependent (LD) start stop
Start w/o load
Critical mode
Inhibit emergency
External acknowledge
Undelayed close GCB
External mains decoupling requested

18. Exercise Create a pulsing relay output Use as many flags as necessary
Relay should pulse in operation mode MANUAL
Use relay 11 as pulsing relay
Change the pulse / pause time

19. Exercise Solution: Create a pulsing relay output
Can be used as a simple process controller if combined with Flexile Limits (alarm class = control). Only discrete PID possible with multiple Flexible Limits and different pulse / pause time
