1 (SYSTEM):
Menu 1-SYSTEM allows to show how the controller connects
to the engine and to the generator and the kind of plant.
Correct setting of these
parameters is paramount as almost all protection activation thresholds are expressed as
a percentage of these parameters.
2 (SEQUENCE):
Working sequence configuration can be modified through the menu 2-
SEQUENCE. In this menu it is possible to set threshold percentages and acquisition times,
plus enabling/disabling operation sequences related functions.
3 (PROTECTION):
Protections management is accessible through the menu 3-
PROTECTION. As to this, it is important to know that, in order to enable/disable a
protection, you may simply modify the associated time, leaving the threshold unchanged:
by setting the time to zero, the protection is disabled. However, this general rule provides
some exceptions. Refer to chapter dedicated to anomalies, par. 0, which describes the
deactivation mode for each one.
4 (AUXILIARY FUNCTIONS):
All operations not related to system, sequence and
protections configuration, can be performed through the menu 4-
AUXILIARY
FUNCTIONS. This menu contains other menus used for configuring engine auxiliary
functions, history logs and serial communication.
5 (COMMUNICATION):
This menu configures the communication via USB
7 (CAN BUS):
The engine menu 7-CAN BUS allows to set the way the controller
communicates on the bus to acquire the engine measures, diagnostics and should need
be, send commands.
8 (PLANT):
Allows to configure the name and the plant type between SSB and SPM

Entering the programming mode of each single parameter, page of fig. 1 is shown.
Each programming parameter (Ref. 3) has a 4-digit numeric code (e.g. P.0125) to identify the
variables regardless of the language used. The current value of the parameter is displayed
below the description Ref.4.
