Assembly Adjustment (Traveling Device)
2.2 Accelerator sensor assembly and
adjustment
[NOTICE]
Do not touch the terminal directly because the
static electricity tolerance of the sensor is weak.
(Execute it after removing static electricity as it
touches other metal parts when it is necessary to
touch the terminal.)
Force must not be applied to the sensor internal
stopper when you adjust the nut for the sensor
shaft fixation.
(Do not apply turning force to the stopper when the
nut is turned toward the stopper from the condition
that the sensor shaft is halted by the stopper.)
1. Installation of lever D
Press-fit it in the thrust at the time of tightening
the nut for the lever fixation so that the load is not
applied in the direction of thrust of the sensor
axis.
2. Installation of spring
Before installing the spring, secure the lever A
using the bolt B. Otherwise, the sensor may go to
the stroke end while the spring is installed and
excessive force may be applied to the stopper
inside the sensor. (When installing the bolt, make
the bolt head protrude further than the regular
position, that is, to allow the accelerator pedal to
be depressed further.)
3. Positioning of lever A
Adjust with bolt B and lock with the nut so that
lever A becomes vertical.
4. Positioning of idle side
Adjust the position of the sensor so that each
sensor output (Out1 (white-black) and Out2
(blue-green)) becomes 0.5 ± 0.1 V when 5 ± 0.1
V is impressed to +V1 (red-black) and +V2
(yellow-green).
5. Positioning of accelerator switch
Adjust the installation position of the accelerator
switch so that accelerator switch change at the
position in which each sensor output (Out1
(white-black) and Out2 (blue-green)) becomes
0.82 ± 0.05 V when 5 ± 0.1 V is impressed to +V1
(red-black) and +V2 (yellow-green).
6. Positioning of full stroke side stopper
Adjust the position of the sensor with bolt C and
lock with the nut so that each sensor output (Out1
(white-black) and Out2 (blue-green)) becomes
4.5 ± 0.1 V when 5 ± 0.1 V is impressed to +V1
(red-black) and +V2 (yellow-green).
[NOTICE]
Adjust the bolt so that excessive force should not
act on the sensor internal stopper when the sensor
reaches the stroke end.
7. Lock six places shown in figure with paint after
adjustment is finished.
