Protections and Alarm management
Protection groups
There are two groups of protections in the controller: fix and customer configurable.
Setpoint group
Analog protections Configurable Analog protect
Generator protections Configurable Gener protect
Mains protections –
should not be used in
MINT application
Configurable Mains protect
Fix protections Fix Engine params,
Gener protect,
Analog protect
Protection types
Because of limited (adjustable) GeCon influence to the Engine and GCB (depends on configuration and
wiring) the GeCon protection system is more focused to fail indication. All Protection types are available
because of IGS-NT system compatibility even if some Protection types has the same result in GeCon (e.g.
BOC, Stp, Sd).

Off load
OfL AUT modes:
Controller opens GCB without soft
unloading, gen-set runs 1 minute at
Nominal RPM. Gen-set state changes to
Running 1 minute after Off load activation.
Controller starts automatically GCB
synchronizing (or closes GCB) when Off
load is deactivated (no fault reset
necessary).
MAN mode:
Controller opens GCB without soft
unloading and the gen-set runs without
load until operator intervention.
All generator protections are active during
Off load duty.

Sensor fail
Fls Can be indicated when Analog input value
is ±6% out of sensor characteristic range.
Fls can optionally activate corresponding
(e.g. Sd) Analog input protection as well.
