Automatic height control
Target selection before lift-up operation
The operator can memorize up to three favorite height
positions (A, B and C) at the higher area than the
height where the inner mast begins to rise.
Target height memory can be selected by click opera-
tion of the load display switch while the lift lever is at
neutral.
The click operation is defined as the brief push opera-
tion of the load display switch (1) within one second.
The long push operation over one second will be
ignored. The controller takes it as the operation to dis-
play the load meter on models with the multi-function
display deluxe (OPT).
Counts of clicks and the selected target memory are
related as follows.
0 : This feature will not be activated.
1 : The lowest target is selected.
2 : The middle target is selected.
3 : The highest target is selected.
When the highest target has been selected, one extra
click returns to the original situation of the count zero.
When the operator is selecting the target, the assistant
screen is displayed as follows.
The order of the height memories is always displayed
on the screen in low order.
Note:
•
The first click always select the lowest target even
if the forks height has already been over the lowest
target position. This is to keep the constant relation
between the number of clicks and the memory to be
selected.
•
No assistant screen is displayed when no position
has been memorized.
Restriction on joystick models
On joystick models, favorite height can’t be selected
during tilting operations. Doing so activates the auto-
leveling function.

Cancel of the target and activation
Displaying the general screen by clicks can cancel the
target before lift-up operation.
The target and the assistant screen are canceled if nei-
ther click nor lift-up operation is done over 10 seconds.
Operating the lift lever downward, or returning it to the
neutral position while this feature is activating also
cancels them.
Operation to stop the selected target
Operating the lift lever upward within 10 seconds with
the target height selected and keeping the lever upward
will stop forks automatically at the selected target.
At that time, the number of the short buzzer sounds
informs the operator of the selected target height as
follows while the lift lever is operated upward.
The lowest target: the single brief buzzer sound repeats
with frequency of 1 second (pi..pi..pi..).
The middle target: two brief buzzer sounds repeat with
frequency of 1 second (pipi..pipi..pipi..)
The highest target: three brief buzzer sounds repeat
with frequency of 1 second (pipipi.. pipipi.. pipipi..)
Note:
•
Returning the lift lever to the neutral position of
course stops the lifting up immediately while this
feature is activating.
•
When a limitation function of the material handling
or the OPS function activates, all the function of
the Height Selector (including the screen) are can-
celed. The movement of the mast is halted.
•
When selecting a favorite height position lower
than the current height, this feature prevent forks
from moving upward.
In this case, the buzzer sounds for a second, and the
screen informs the operator of the invalid opera-
tion.
