JOYSTICK CALIBRATION
The joystick calibration should be completed if the joystick
is replaced. To perform the joystick calibration both emer-
gency stop switches must be pulled out (reset) and the
ground control keyswitch set on platform mode.
1.
Plug the analyzer into the machine, “Help Press
Enter” should be displayed on the analyzer dis-
play.
2.
Press the right arrow key to “Access Level 2".
3.
Press Enter once. At this screen, you are asked to
enter a password: Enter “33271” by doing the fol-
lowing:
a.
Using the up and down key enter the first
number.
b.
Right arrow key once and enter the next
number.
c.
Repeat steps A and B until you have entered
“33271” and press Enter.
d.
Access level 1 should be on the display.
4.
Press right arrow key to “Calibrations” and press
Enter once.
5.
“Calibration: Joystick” should appear, press Enter
once.
6.
“Cal Joystick: Yes: Enter, No: Esc” should appear,
press Enter once.
7.
“Cal Joystick: Fwd to Max” will appear. Move joy-
stick completely forward and hold, then press
Enter.
8.
“Cal Joystick: Center” will appear. Release joy-
stick to the neutral position and press Enter.
9.
“Cal Joystick: Rev to Max” will appear. Move joy-
stick completely in the reverse position and
hold, then press Enter.
10.
“Cal Joystick: Complete” will appear. Power
down the machine.
5.3
TILT SENSOR CALIBRATION
Be sure that the machine is parked and stowed on level
ground.
NOTE:
Tilt Sensor Calibration can not be performed if the
main contactor switch is open due to an alarm.
1.
Enter Access Level 1 and go to the CALIBRATION/
TILT SENSOR/LEVEL VEHICLE screen.
2.
Choose the right arrow key to view the raw,
uncalibrated tilt sensor values. If either raw angle
reads
5.0 or more, the machine is too unlevel
and the software will prohibit calibration. There-
fore, attempt to dissect the three areas of error
to find the primary contributor:
a.
Machine mounting and/or grade:
Try to measure the top of the tilt sensor for
levelness. If unable to get a good reading,
unbolt the tilt sensor and check the sensor’s
mounting surface for levelness.
b.
Observe whether the tilt sensor is properly
seated.
c.
Tilt sensor has developed an offset shift:
Keep the tilt sensor electrically connected.
Level one axis of the tilt sensor and observe
the raw reading (should be within ± 2.0). Do
the same for the other axis. If either axis is
greater than ± 2.0, replace the tilt sensor.
NOTE:
Check that the tilt switch is properly set by referring
to the Tilt Activation Settings table in Section 1 of
this manual.
Tilt Sensor Failure Troubleshooting
Some possible reasons that the tilt sensor will not cali-
brate are:
a.
The surface the machine is sitting on is off
level by a few degrees (flat doesn’t imply
level; parking lots are often not level).
b.
The tilt sensor has failed one or both of the
channels (X axis and Y axis).
c.
Tilt sensor has moisture intrusion that has
shifted its output.
d.
Water and/or corrosion in the sensor has
corrupted electrical connections or caused a
tilt sensor failure (observe any cracks in the
housing).
For the following troubleshooting steps, a bubble level
(smaller is better) will be needed and the machine must
be on a level surface:
1.
If the Analyzer displays angles other than +20.0°,
attempt to calibrate. If machine won’t calibrate,
note the reason displayed on Analyzer:
a.
SENSOR FAILURE – tilt sensor internal fre-
quency is out of range (replace sensor).
