Enabled in: MAN, AUTO, TEST, REMOTE START
Override: -
This protection is activated if the measure of the auxiliary source current remains continuously
above to threshold P.9736 for time P.9737.
Type: Latched warning
Related parameters: P.9731 Auxiliary source current hysteresis.
P.9738 Auxiliary source reverse current threshold.
P.9739 Auxiliary source reverse current delay.
To disable: P.9739 = 0
Enabled in: MAN, AUTO, TEST, REMOTE START
Override: -
This protection is activated if the auxiliary source current is negative and has an absolute value
continuously above threshold P.9738 for time P.9739.
Type: Warning
Related parameters: -
To disable: -
Enabled in: MAN, AUTO, TEST, REMOTE START
Override: -
When GCB is closed, and the generator is connected to the plant battery and/or to the auxiliary
source, the DC voltage measured by the controller is not the generator voltage, but the
common bar voltage. Thus, the controller is not able to detect faults on the generator and
signals this situation through this warning. You can avoid this problem in three ways:
•
Connecting also at least one AC voltage (separated from the common bar by the
rectifier diodes).
•
If the controller acquires the engine speed, it can at least detect if the engine is
stopped or if it is running outside the seed limits.
Type: Warning
Related parameters: P.9751 Loads current hysteresis.
P.9752 High loads current threshold.
P.9753 High loads current delay.
To disable: P.9753 = 0
Enabled in: MAN, AUTO, TEST, REMOTE START
Override: -
This protection is activated if the measure of the loads current remains continuously above to
threshold P.9752 for time P.9753.
Type: Latched warning
Related parameters: P.9754 Max loads current threshold.
P.9755 Max loads current delay.
To disable: P.9755 = 0
