Alarm
Display all alarm information, including warn, shutdown alarm, trip shutdown and trip but not shutdown.
NOTE:
For ECU alarms and shutdown alarms, if the alarm information is displayed, check engine according to it,
otherwise, please check the generator manual according to SPN alarm code.
⚫
Event log

Input
Input
Load is inductive resistance.
COS>0C
P>0, Q<0
Input
Output
Load is capacitance resistance.

Input
Load is equal to one under excitation
generator.
COS<0C
P<0, Q<0
Output
Output
Load is equal to one over excitation
generator.
Remark:
1.
Input active power, generator sends active power to load.
2.
Output active power, load supplies electricity to generator.
3.
Input reactive power, generator sends reactive power to load.
4.
Output reactive power, load sends reactive power to generator.
