e. The Ground Control Box, as mounted on the machine, does not allow the tilt sensor to be level.
For the following troubleshooting steps, a bubble level (smaller is better) will be needed and the machine must be on a level
surface:
1. On the Analyzer, go to Diagnostics/System and read the tilt angle. If either angle reports +20.0°, there is an electrical/
electronic failure (tilt sensor, control board, electrical connections).
a. Open the Ground Control Box.
b. Disconnect the sensor and clean any corrosion off of the tilt sensor and control board connections.
c. Reassemble and test. If fault persists, replace tilt sensor.
2. If the Analyzer displays angles other than +20.0°, attempt to calibrate. If machine will not calibrate, note the reason dis-
played on Analyzer:
a. SENSOR FAILURE – tilt sensor internal frequency is out of range (replace sensor).
b. NOT LEVEL - tilt sensor has either developed an offset or it is to unlevel as mounted on the machine.
Joystick Calibration
(Software 1.5 and Higher and Higher)
Using the Analyzer, in Access Level 1, go to MENU: CALIBRATION: JOYSTICK and press ENTER.
1. Following the analyzer screen prompts:
a. Move the Joystick FORWARD and press ENTER.
b. Allow Joystick to be in CENTER position and press ENTER.
c. Move the Joytstick REVERSE and press ENTER.
2. CAL COMPLETE or CAL FAILED will display on the analyzer.
3. Possible reasons if calibration failed:
a. The forward position must be a lower voltage than reverse position.
b. The difference between center and forward & center and reverse must be atleast 1V.
