SENSOR ADJUSTMENT FUNCTION
This function offsets the error caused by the mounting of the potentiometer and makes it possible to detect the cor-
rect position data for the work equipment.
Always carry out this function when replacing the controller potentiometer or work equipment.
SENSOR ADJUSTMENT METHOD
1. Set the work equipment to the lift arm top end position.
2. Keep remote positioner LOWER position set switch (1) and
remote positioner RAISE position set switch (2) pressed at
the same time for at least 3 seconds.
When remote positioner LOWER set pilot lamp (3) and
remote positioner RAISE set pilot lamp (4) light up, release
the switches and set to the sensor adjustment mode.
3. The remote positioner LOWER set pilot lamp (3) and
remote positioner RAISE set pilot lamp (4) light up for 2
seconds, and when both lamps go out, the offset is
recorded in memory.
4. If the lamps flash in Step 3, the potentiometer output is not
within the offset range, so adjust the potentiometer mount.
Adjustment can be carried out at the posture in Step 1.
REMARK
After adjustment each potentiometer,always carry out Steps 1
and 2 again, and check that the condition in Step 3 is correct
(the set lamps light up for 2 seconds and then go out).
ADJUSTING REMOTE POSITIONER
When the lift arm has been removed or the setting does not work efficiently, please contact your Komatsu distribu-
tor for adjustment.
