TILT SENSOR
TILT SENSOR SWITCH
The tilt sensor is incorporated in the EZ120 control module. The switch is activated if the machine
inclination is greater than 1.0° side to side or front to back. This results in a continuous audible alarm
and lift disabled. The only way to stop the alarm from sounding is to return the machine to an inclina-
tion level below 1.0° side to side and front to back. The settings of this limit is preset at the factory
and should on no account be adjusted.

If the EZ120 control module is replaced and/or moved within the
machine for any reason, the tilt sensor must be reset for 0° using the
procedure provided. Failure to do so could result in serious injury or
death.
To follow the procedure, rst connect an EZcal calibrator into the diagnostic port in the lower control
box.
1. Place the machine on a rm level surface ≤ 0.25°.
2. Use a gauge to conrm that the front and rear of the chassis are level to within +/- 0.25° in both
directions.
3. Switch the machine on and the EZcal menu should appear.
4. Scroll to access level and hit “Enter”.
5. Enter code 2222 for access level 2 and hit “Enter”.
6. Scroll to setups and hit “Enter”.
7. Scroll to tilt setups and hit “Enter”.
8. Choose calibrate level and hit “Enter”.
9. Hit “Enter” for yes for the machine tilt setup should be complete.
To conrm the calibration has worked, switch the machine off and then on again.
10. Scroll to diagnostics and hit “Enter”.
11. Search for system and hit “Enter”.
12. Scroll to tilt and both readings should be below 0.2°. If not, repeat from #3.
