Start blocking 

This message means that a binary input with Startblocking function is active and engine 
start is blocked. If active, NotReady state is shown on the controller screen and the mes-
sage appears in the Alarm list. As soon as input is deactivated, engine start is enabled 
again.

Warning protection on AI Cylinder temperature 1-32 is active. Check corresponding set-
points in the 

Engine protect 

group. 

Wrn MCB fail

regulation loop, Angle regulation loop and Voltage regulation loop are active during syn-
chronisation and you may need to adjust their setting. 
Actual state of synchronization is visible on the controller measurement screen with syn-
chroscope where speed and voltage regulator's outputs, slip frequency and generator 
and mains voltages can be observed during the synchronization process.

and 

Gen V del 

set-

points. This alarm is issued if voltage protections are based on phase to neutral voltages. 
It means that
