LCD lighting
The back light lamp is managed by the Gen-set control module, which switches off the back
light after a programmable time (P.0492) if no buttons are pressed in the meantime. To turn it
on again it is enough to push any key. This function can be disabled by setting parameter
P.492 to 0.
.
During engine starting phase, the lamp is automatically turned-off to reduce the power
consumption of the controller board, in order to ensure greater autonomy for the controller
itself in the event of critical conditions of the starter battery. Using the P.0493 parameter, you
can force the lamp to stay always on when is engine is started.
