Easy Gen-3400XT-P1/3500XT-P1/3500XT-P1-LT series generator set control system provides comprehensive function and status indication. Its HMI is consistent with the function sequence and structure of ToolKit, but full access to all parameters and settings is limited to ToolKit. LT model is equipped with a heatable display screen, which automatically starts heating when the ambient temperature is lower than-20 C, and the power consumption increases by 7.5W during heating. HMI buttons can be locked or unlocked through LogicsManager. The front panel contains soft key groups such as display screen, mode, operation, navigation, home page and alarm. The system status is displayed by communication and operation indicator lights. The communication status indicates the data reception of CAN port, and the operation status reflects the equipment readiness and alarm status. The control system supports a variety of application modes, including circuit breaker-free control, generator circuit breaker control, main circuit breaker control and combined control modes, and each mode provides engine/generator parameter measurement, start-stop and protection functions. The application modes include None, GCB open, GCB, GCB/MCB, GCB/GGB, GCB/GGB/MCB, GCB/LS5, GCB/L-MCB, GCB/GGB/L-MCB and GCB/L-GGB/L-MCB, and some modes support automatic power failure operation. The system provides four operation modes: automatic, manual, test and shutdown, and the plastic shell version can be selected by the front panel button.

System Overview

Display And Status Indicators

HMI and ToolKit are aligned for the same sequence and structure of functions and parame ters.

Restrictions Full access to all parameters and settings with ToolKit only!

Low ambient temperature (LT) .... easYgen-3x00XT-P1-LT - the special version of the plastic housing device with HMI/display - is equipped with a heatable display. Heater is automatically switched ON when ambient temperature drops below -20 °C and the result [86.34 LM: Enable heater] (11972) of LM [7799 Enable front foil heater] is TRUE. Even if the device has no front foil heater because it is no ... LT variant, both the LogicsManager and the parameter are available but without function! During heating period the power consumption is increased by 7.5 W.

WARNING! 

 HMI buttons can be locked! HMI buttons can be locked/unlocked with the LogicsManager LM 12978 Ä p. 139/Ä p. 908 [Lock keypad]. Check/use with Logical Command Variable 86.30 (11924).

C "Operation"- Used to perform manual operation of the genset and the breakers (Single Line Diagram). Sometimes used for settings' input. D "Navigation"- Navigation between system and configuration screens, and alarm list.

System Overview

n “Communication” for visualizing communication state:

– Off: no data received by any CAN port

– Toggling green/off: any data is received by any CAN port

– Red: missing member alarm is active

– Toggling red/green: missing member is active and data received by any CAN port n “Operation” for device state indication:

– Off: the unit is not ready for operation (depending on LogicsManager "Ready for operation)– Green: the unit is ready for operation and no alarm is active or latched– Toggling green/red: the unit is ready for operation and a warning alarm in the system is active or latched– Red: the unit is ready for operation and a shutdown alarm in the system is active or latched.– Green blinking fast (about 6 times per second) and red is permanently off: Internal copy process after flashing a soft ware update is still running or "Load default settings" is initi ated

n AUTO n MANUAL (MAN) 

n TEST n STOP 

n ... and an internal (non) operating phase during starting the device itself

The plastic housing (HMI) version of the easYgen-3000XT enables to select an operation mode by pressing the according button at the front panel - if current settings allow this function.
