Tilt Sensor - JLG Toucan 12E Service And Maintenance Manual

SECTION 8 - CONTROL COMPONENTS
If the sensor is forced on the opposite stop the output volt-
age is: 0.9x (Sensor Power Voltage) = 3.78V - 3.96V).

NOTE: Refer to Section 4-3 for Steering Sensor Installation.

Tilt Sensor

The tilt sensor is located on the chassis base plate, behind
the right rear wheel.
Figure 8-19. Tilt Sensor
The control system monitors the tilt sensor to determine if
the vehicle is tilted excessively. If the vehicle tilt angle in
any direction is greater than 3 degrees, the control system
considers the machine tilted.

Tilt Sensor Calibration Verification:
1. Power the machine on at ground control station and
slightly raise the mast to actuate the main mast limit
switch (Refer to Figure 8-8).
2. Place a spirit level (digital display) longitudinally (1)
on the chassis (front - rear direction).
3. Using a jack (3) of appropriate capacity, slowly and
carefully lift the front of the chassis: the LED under
the tilt sensor body should switch off when the chas-
sis angle reaches 3 degrees. The warning alarm
should be triggered approx. 1 second later.
4. Place a spirit level (digital display) transversely (2)
on the chassis (left - right direction).
5. Using a jack (3) of appropriate capacity, slowly and
carefully lift the side of the chassis: the LED under
the tilt sensor body should switch off when the chas-
sis angle reaches 3 degrees. The warning alarm
should be triggered approx. 1 second later.
6. If the LED switches off before 2.5 degrees or after
3.1 degrees in either direction, perform a new cali-
bration procedure and verify calibration again.
