•
The deviation is less than the alarm set point, and the alarm is not activated.
3. The controller is running fixed cos phi regulation with a set point of 0.9 I, and the measured value is 0.95 C.
•
The deviation from the set point is |(0.95 C - 0.9 I)| / 0.9 I × 100 = 17 %.
•
The deviation is less than the alarm set point, and the alarm is not activated.
6.8.3 P load sharing failure
This alarm is for genset active power load sharing failure.
The alarm is based on the absolute value of the difference between the measured value and the internal controller set point, as a
percentage of the genset nominal power.
The controller activates the alarm if the difference between the reference and measured values is outside the activation range for
longer than the delay.
INFO
This alarm is not activated when the deviation of the error swings in and out of the activation range above and below the
set point. This is because this alarm is only activated when the deviation of the error stays either above or below the
activation range for the delay time.

6.8.4 Q load sharing failure
This alarm is for genset reactive power load sharing failure.
The alarm is based on the absolute value of the difference between the measured value and the internal controller set point, as a
percentage of the genset nominal reactive power.
The controller activates the alarm if the difference between the reference and measured values is outside the activation range for a
time longer than the delay.
INFO
This alarm is not activated when the deviation of the error swings in and out of the activation range above and below the
set point. This is because this alarm is only activated when the deviation of the error stays either above or below the
activation range for the delay time.
