Introduction Description Introduction This brief manual must be used together with the standard manuals The following standard manuals are required to install, commission, and operate the easYgen-3500XT Packages P1, P2 with Option K51 and the Group Controller: easYgen-3000XT Series Manual (No. 37580 –...
Parameter “Application mode” (3444) is fixed to “GCB/LS5.” This is because some functions of the Group Controller bear resemblance to Woodward's LS5 device. (For this reason, in some screens "LS5" will appear, even though there is no LS5.) Parameter "Load share interface”...
Additional Functionality Application > Droop configuration The K51 easYgenXT (GC mode enabled) which has triggered the "Missing easYgen alarm" delays its dead bus closure depending on its device number. This is cascaded through: (Device number easYgen) x 0.5s. The GC dead bus closure is not delayed, if the "Missing easYgen alarm"...
Additional Functionality Communication Management / D... 3.2.3 Home Screen If GC mode is on, it is possible to show the mains data measured by the Group Controller “Mains (GC)” like in the screen below. If this is wished, parameter “4103 Home screen data” must be con‐ figured to “Generator/LS5”...

Additional Functionality Communication Management / D... Example 1 The following HMI screen shows two easYgen devices taught in: the load share interface is configured as “CAN/Ethernet A”. Device 1 is OK, device 3 is only available on CAN (this means: Ethernet A failure).

Additional Functionality Communication Management / D... Example 3 This screen shows the Group Controller (device 32) as taught in, but it is not recognized anymore. For this reason, command vari‐ able “02.40 Ä p. 16 Own GC not recognized” becomes active. “02.40 Ä...
Additional Functionality Group Controller alarms Group Controller alarms Handling of Group Controller alarms The alarms of the Group Controller are available in the easYgen as Ä Chapter 3.6 “Logical Command in the easYgen command variables. (Refer to Variables (CV)” on page 16 ) These command variables can be assigned to the “Free Alarms”.
Additional Functionality Parameter overview Alarm “Interface redundancy error” If the application needs an alarm, where the redundancy of the load share interface is lost, “Free Alarms” may be used. Like the standard easYgen device, the K51 provides 16 free alarms. They can be used to drive additional alarms from the LM command var‐...
