EXAMPLE:
This is an example of Test on Load function when: ProcessControl:Island enable = ENABLED,
ProcessControl:Parallel enable = DISABLED and ProcessControl:Synchro enable = NONE.
Controller mode is changed to TEST mode. Gen-sets are started by SYS START/STOP activation.
Logical Binary Input TEST ON LOAD is activated. Because Island operation is enabled, but Parallel
operation is disabled, controller will perform Test on Load with Break. See the figure below for detailed
path.
