The telescoping cylinder is locked to a telescoping boom
section (no unlock symbol shown near the graphical
representation of the tele cylinder - refer to Item 1 in
(Figure 3-65)).
The telescoping boom section is unlocked (the unlock
symbol is shown near the graphical representation of the
section pins - refer to Item 2 in (Figure 3-65)).
In the top row of the proximity switches, S2110N is on, the
others in the row are off. In the middle row of the proximity
switches, S2118N is on, and the others in the row are off.
Retracting and locking a telescopic section
During telescoping motion you are not to select Lock. Under
no circumstances, while the tele cylinder is moving, should
you select and press the symbol (4, (Figure 3-65)).
• Retract the telescopic section slowly and as far as
possible, refer to (Table 3-2.) for the expected value for
the precision length sensor (Item 2 in (Figure 3-64))
when the boom sections are fully retracted.
• Now select and confirm the symbol (1, (Figure 3-65)).
The telescopic section can be locked (if the actuator is able
to release the section pins, and the telescoping boom
section is actually aligned with a pinning hole). The screen
should appear as shown in (Figure 3-68). In particular,
S2111N should be ON.
CAUTION
Machine damage hazard!
If you select Lock during telescoping, the locking pins on
the telescopic section are slid out immediately and they
can damage or tear the electrical or hydraulic components
in the main boom.
