less than under frequency limit for 10s, and it alarms.
Detected after safety on delay; when temp. high is
above high temp. limit for 3s, it will issue alarm;
Detected after safety on delay; when temp. high input is
active, it will issue alarm;
Detected after safety on delay; it alarms when oil
pressure low input is active;
Action is set to Warning; Gen current is over pre-set
value, and lasting time surpasses delay time, it alarms;
Action is set to Shutdown; Gen current is over pre-set
value, and lasting time surpasses delay time, it alarms;
Action is set to Cooling Shutdown; gen current is over
pre-set value and lasting time is over delay, it alarms;
Detected after safety on delay; gen voltage is over the
threshold, and this lasts for over delay, and it alarms;
Detected after genset running; gen voltage is lower
than threshold for over the delay time, and it alarms;
It alarms when starter doesn't start the engine in the
range of the pre-set start times;
When "outside shutdown alarm" is configured for the
input port, and when the input is active, it alarms;
When fuel level is lower than the threshold for 10s, it
alarms;
When fuel level low input is active, it alarms;

completely and controller will alarm;
Battery voltage is lower than the threshold for 20s, it
alarms;
Battery voltage is higher than the threshold for 20s, it
