Optical height measuring system
(variant)
This truck is equipped with an optical height
measuring system. The system is immedi-
ately available after the truck is switched on.
The components are located to the side on the
lift mast. The system consists of a compact
LED/sensor unit on the lift mast frame and a
reflector on the fork carriage.
The LED height sensor (1) sends a light signal.
The signal is reflected by the reflector (2). The
truck calculates the lift height based on the
time taken for the light signal to travel.
The current lift height (3) is permanently
displayed in the display. The displayed lift
height corresponds to the height of the upper
edge of the fork. A different value can be set
by the authorised service centre.
The system functions across the entire fork lift
height, from ground level up to the maximum
lift height of the truck. When used properly,
the measurement accuracy is +/- 5 mm.
The maximum measurement accuracy is
+/- 50 mm.
The red light emitted by the LED/sensor unit is
not dangerous to the human eye. Due to the
level of brightness, the effect of looking directly
at the light may be short-term dazzling.
NOTE
The LED height sensor and reflector are
adjusted at the factory. Follow-up adjustments
must be performed by the authorised service
centre.
