4.6.6 Reversing fan mode (optional)
Depending on the operating conditions of the
machine, the cooling system,
 water/charge air cooler
 and hydraulic fluid cooler
can be equipped with reversing fan mode as
an option.
The air flow can be reversed from the ma-
chine control unit, allowing the fan to blow
freely without interrupting operation. Loose
impurities are eliminated and the required
cleaning cycles, which are essential for proper
functionality of the cooling system, are ex-
tended to 24 hours depending on usage con-
ditions.
Fan reversing mode can be switched on by
briefly pressing the F3 function key on the
multifunction display. The fan icon (58/43)
appears against a green background with a
black arrow pointing forward. The time re-
maining until the next reversing phase also
appears in the green fan icon. The reversing
function starts automatically when the preset
interval time is reached. When reversing fan
mode is active, the background of the fan icon
(58/43) lights up yellow with a red arrow point-
ing backward. The text message (58/47)
"REVERSING FAN MODE" appears.
The reversing fan menu can be accessed by
pressing and holding down the F3 function
key (see Fig. 59). The interval between re-
versing phases can be set to any value be-
tween 15 and 60 minutes in the reversing fan
menu.
The reversing fan function can be turned off
by briefly pressing the F3 function key. Then
the fan icon (58/43) appears against a black
background.
