SECTION 8 - CONTROL COMPONENTS

Tilt Sensor Check:

Wedge a block (P/N:ST2741 - located in the manual stor-
age container) to activate the tilt sensor and keep it tilted
as shown following.
Figure 8-15. Tilt Sensor Check
NOTE: When tilted, the green LED at the bottom of the sen-
sor body switches off indicating that the output sig-
nal has been cutout. Tilt sensor output signal cutout
is delayed (Approx. 1 second).
From the platform control station, raise the mast by
approximately 1m.
• Confirm an audible alarm sounds.
• Verify the tilt indicator (red) blinks.
• Check the following functions are affected:
- Drive function disabled.
- Mast/Jib lift-up and swinging movements can be per-
formed only in creep mode.

Tilt Sensor Calibration:

Set the machine on a known leveled surface. Position a
spirit level (digital display recommended) longitudinally
and transversely on the chassis base plate to confirm the
machine is leveled.
With the machine powered on, use an electrical wire to
connect the battery NEG. (i.e. [B-] post of a power mod-
ule) to the terminal block of the tilt sensor. The LED at the
bottom of the sensor body will blink, indicating the new 0
degree position has been defined.

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 2 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 2 degrees. The warning alarm
should be triggered approx. 1 second later.
6. If the LED switches off before 1.8 degrees or after
2.1 degrees in either direction, perform a new cali-
bration procedure and verify calibration again.
