breaker cannot close in the case of a phase speed alignment error.
Selecting MAN mode by pressing theUP
of GCB via manually assisted syncronization (depending on plant's type).

Note: The function described can only be used if the system hasn't been configured to use an external potentiometer to
adjust the speed; in this case the speed can only be changed using the potentiometer.
Make sure that after the circuit breaker closes, the requested speed is set as close as possible to the
nominal value so that Gen-set can properly adjust the power.
3.5.2
Manual power adjustment
Warning: As some slow power ramps may have been set, check the command against the "Power
reference" value shown in the same page and not against the value of the power actually produced.
In mains parallel applications with BASE LOAD or IMPORT/EXPORT functions, you can adjust the power supplied
manually without having to change the parameter that defines the regulated power directly.
Display screen B.03 and press the ACK/ENTER
