CAUTION
Risk of damage to the LED lift height sensor through
high-pressure cleaning!
A high-pressure cleaner can damage the LED lift
height sensor due to the penetration of water. This
can result in incorrect measurements.
–
Do not direct the spray from a high-pressure
cleaner at the LED lift height sensor.
Eliminating malfunctions
NOTE
A misaligned LED lift height sensor or bent
reflector must be adjusted only by the author-
ised service centre.
–
If the malfunction in the system persists,
please contact the authorised service cen-
tre.
If a malfunction occurs, the message
Check
lift height sensor and reflec-
tor
appears in the display-operating unit. If
the malfunction no longer exists or has been
rectified, the system is automatically available
again.
Truck functions that are dependent on the lift
height are restricted in the event of a malfunc-
tion in the height measurement system. Mal-
functions must therefore be rectified immedi-
ately.
Contamination
The driver can resolve a temporary interrup-
tion of the light signal due to contamination
or foreign objects in the signal path. See the
section entitled "Cleaning".
Condensation/icing
If the truck switches between a very cold en-
vironment, e.g. in a cold store, and normal
surroundings, ice or condensation may form
on the sensor. The signal may then briefly fail
until the condensation or icing has subsided.
