Load measurement (variant)
NOTE
After changing the load lift system (fork
arms, fork extension, attachments), the load
measurement system must be calibrated.
Only then is a correct load measurement
ensured. Calibration must be performed by
the authorised service centre.
General
The "load measurement" variant helps the
driver by displaying the weight of the lifted load
on the display and operating unit.
The weight is measured by an additional
weight sensor at the valve block. The sensor
measures the weight with a deviation of
+/-10% of the nominal load of the truck.
The calculated data is also evaluated by
assistance systems such as OPTISPEED
and Active Load Stabilisation (ALS).
To ensure correct functionality, the load
measurement must be performed once
for testing purposes as one of the daily
commissioning tasks for the truck.
Requirements for load measurement
The load must be in the inactive position so
that the weight sensor provides accurate
results.
For this reason, load measurement is disabled
during the following truck activities:
• Driving
• Lifting
• Lowering
Once the fork has been in the inactive posi-
tion for two seconds, load measurement is
enabled. Load measurement is now possible.
The measured weight of the load is shown on
the display and operating unit.
If the button for load measurement is pressed
while load measurement is disabled, " - -
- - " is displayed instead of the measured
weight. After a maximum of ten seconds,
