Determining the Error Type
• Check which emergency program procedure is suitable
for the current error:
If the display (2, Figure 4-135) shows an obviously
unrealistic value, such as -1100 mm, then there is an error on
the precision length sensor length indicator of the Crane
Control System. Contact Manitowoc Crane Care or your
Local Distributor to determine if you are permitted to start the
telescoping process. Item 1 is the time remaining to correct
the error.
In the display, items 3 and 4 (Figure 4-135) are examples of
indicators for proximity switches. Item 3 is switch S2112N,
and it is shown in a dimmed fashion. This means the switch
has been considered OFF. Item 4 is switch S2118N, and it is
shown in active colors; this switch is considered ON.
The switches at the top row (S2110N, S2111N, and S2122N)
indicate whether or not a tele section is pinned (locked) to
the next outer tele section. Switch S2110N, when
highlighted, indicates the section is not pinned (locked) to its
next outer section. Switch S2111N and its redundant switch
S2122N, when highlighted, indicate the tele section is pinned
to its next outer section.
The next row (S2117N, S2118N, and S2116N) are indicators
for the tele cylinder being aligned with a boom section.
S2117N is shown to the left; when the tele cylinder is nearly
aligned (for instance within 50 mm or 2 inches of the
connection), and S2117N is ON, then the cylinder needs to

CAUTION
Machine damage hazard!
Ensure that you always have an overview of the current
status of the telescoping mechanism before you initiate
locking or unlocking.
In emergency mode, there may be no monitoring of
prerequisites – the function is performed immediately
after pressing the button.
CAUTION
Machine damage hazard!
Never telescope the main boom if it is not possible to
monitor the length of the tele cylinder by some means.
It would then not be possible for you to monitor
operations, and components in the main boom could be
damaged, or a situation could arise in which the main
boom can no longer be extended or retracted.
