n
– The discrete input has been assigned a default function
using either the LogicsManager or preconfigured alarms

– The following sections describe how these functions are
assigned.
– The function of a discrete input can be changed if required.
– The following description of the inputs, labeled with "pro‐
grammable", refers to the preconfiguration.

Energized
If the unit is in the AUTOMATIC operation mode (selected
with the operating mode selection push button on the front
panel) the controlled engine is started automatically.
De-energized
The engine is stopped.
Energized
The MCB is enabled and closure of the breaker is per‐
mitted.
De-energized
The MCB is not enabled and closure of the breaker is not
permitted. This function permits a supervisory control (i.e.
a PLC) to allow the closure of the MCB by the easYgen.
