Woodward easYgen-3000XT Series, Manual, Page: 582 / 1205

If there are more than one failures only the first incoming failure will be indicated and is
available at protocol 5014.
If there is no alarm this number is 0.
• Check 1: The easYgen tries to close the GCB, but the generator is not within its •
operating range (parameters ╚═▷ 5800 , ╚═▷ 5801 , ╚═▷ 5802 , or ╚═▷ 5803 ).
• Check 2: The easYgen tries to synchronize the GCB, but the busbar is not within the •
generator operating range (parameters ╚═▷ 5800 , ╚═▷ 5801 , ╚═▷ 5802 , or ╚═▷
5803 ).
• Check 3: The easYgen tries close the GCB in breaker transition mode "Open •
transition" with GCB and MCB open status. In this condition the busbar is expected
as dead, but the busbar voltage is NOT below the dead busbar detection limit
(parameter
╚═▷ 5820 ).
• Check 4: The easYgen wants to close the GCB onto a dead busbar, but the device •
cannot close the breaker because there is at least one neighbor device recognized
with a closed GCB.
• Check 5: The easYgen tries to synchronize the GCB, the MCB is closed, but mains •
and/or bussbar are not within its operating range (parameters ╚═▷ 5810 , ╚═▷ 5811 ,
╚═▷ 5812 , or ╚═▷ 5813 ).
• (Checks 6 to 10 are intentionally NOT available in easYgen-3100XT/3200XT.) •
• Check 11: The easYgen checks the plausibility of generator and busbar, if GCB is •
closed and the engine runs without run-up synchronization, but the operating range
of generator OR busbar is not matched.
• Check 12: The easYgen checks the phase rotation of generator, busbar, and mains •
and a synchronisation shall be executed, but the phase rotation of all systems does
not match. (Synchronisation is blocked.)
No alarm will be issued in idle mode. This monitoring function is disabled below firing
speed.
NOTICE!
If load-dependent start/stop (refer to ╚═▷ “4.4.5.5 Load Dependent Start/Stop (LDSS)” ) is
enabled, this monitoring function must be configured with a shutdown alarm class C, D,
E, or F) or disable load-dependent start/stop if triggered to ensure that the next engine
will be started.
If this protective function is triggered, the display indicates "Operat. range failed" /
("Operating Range failed") and the logical command variable "06.31" will be enabled.
