This protection is only enabled if the controller has been started by the controller (if the
command for the fuel solenoid is activated) and is disabled in the engine start/stop phases. It
is enabled if, under the conditions previously mentioned, the generator frequency exceeds
continuously the threshold P.0307 for the time P.0308.

This protection is enabled only if the controller is configured to use signal D+ (P.4041 =
AIF.1300 -
“Signal D+”) and if that signal is physically linked to connector JL. The protection is
enabled if the engine was started from the controller (if the command for fuel solenoid is
activated). It is activated if voltage on the D + signal remains below threshold P.0230
consecutively for P.0349 time.

The controller realises a depending on time protection in current (which therefore intervenes
as quickly as the current is in overload). The used curve is named EXTREMELY INVERSE,
and implements an I
