At excessive use of the retarder, the oil and coolant temperature may increase significantly.
When the coolant temperature is too high, the control of the gearbox will switch back the retarder
automatically. The braking force then decreases.
Keep an eye on the cooling water sensor on the control panel when the retarder is used excessively.
The
orange indicator
, the
red error message light
and the
buzzer
will become active if the coolant
temperature is higher than or equal to 110°C.
Measures to prevent high oil and coolant temperature:
•
Switch the
gearbox
one or more gears lower;
•
Switch the
retarder
to a lower position (
position 1 or 2
);
•
Turn off the
retarder
completely.
If these measures do not help to lower the oil temperature, the
retarder
will be automatically turned off.
