Additional function “Warming Up”
The expression “Warming Up” means “engine running without shifting gear”, which en-
ables, for example, warm-up of a cold power unit across the entire speed range. The
gearbox clutch is not engaged in lever position
Á
.
Starting the “Warming Up” function:
.
The “Warming Up” function can only be started at an active command master and only
from the position “
À
neutral”.
1. Set the control lever of the command master in position “
À
neutral”.
2. Press the key “Command takeover” and keep it pressed.
3. Set the control lever of the command master in position “
Á
gearbox forwards / re-
verse”.
The “Warming Up” function is indicated acoustically by a short “double beep” tone
and visually by a brief, rhythmic extinguishing of the command master lighting.
4. Release the “Command takeover” key.
The engine idles and the gearbox clutch remains disengaged. The control lever can now
be moved towards position “
Â
maximum engine speed”. The entire engine speed range
between the positions
Á
and
Â
is available.
.
In the case of twin-engine systems, any power unit can be run separately.
Quitting the “Warming Up” function:
To exit from the “Warming Up” function, the control lever of the command master must be
set to position “
À
neutral”. The normal “beep” tone sounds for the “Neutral position”. The
command master lighting returns to continuous light. The function is disabled.
Note:
If the control lever is shifted from “Forwards” to “Reverse” or vice versa during
the “Warming Up” function, the “Warming Up” function stops automatically when
position “
À
neutral” is reached. When position “
Á
gearbox forwards / reverse” is
reached again, the gearbox clutch would be engaged again.
