Cause
Comparison of telescoping
diagram between crane
control and RCL resulted in
differences
There is no capacity diagram
available for the entered rig-
ging mode
Main boom angle too small
(not steep enough)
Main boom angle too large
(too steep)
There is no RCL code available
for the entered rigging mode
Lattice extension inclination is
too small
Lattice extension inclination is
too large
Current load greater than
derricking load – Lower lattice
extension movement is
disabled
Maximum permissible slewing
angle exceeded
Minimum load value not
reached
Fuse F1 blown
Fuse F2 blown
Fuse F3 blown

Remedy
Compare the actual telescoping sta-
tus with the values on the ECOS dis-
play and, if necessary, re-enter the
telescoping status.
Accept the ECOS telescoping position
data if an incorrect telescoping posi-
tion is displayed on the RCL:
>
1. Press the button once and
the RCL shows the new values
2. Acknowledging the error
Re-enter the current rigging mode. If
the error is displayed again, check
whether the current rigging mode is
permissible.
Raising the main boom
Lower the main boom
Re-enter the current rigging mode. If
the error is displayed again, check
whether the current rigging mode is
permissible.
Raise the lattice extension
Lower the lattice extension
1. Raise the lattice extension
Y
2. Press button
3. If necessary, increase the work-
ing radius using the Lower main
boom movement.
Slew into a permissible working
range.
When the main boom is set down,
raise main boom and acknowledge
the error.
Notify Manitowoc Crane Care if the
error cannot be acknowledged.
