Code
Error Cause Elimination
E82
Too large difference
of the luffing jib
angles at tip and base
jib.
 The angle as to the horizontal
on the jib head exceeds the
luffing jib angle by more than
5 degrees.
 Check angle sensor on the jib
head.
 Check angle sensor on the jib
base.
E83
Maximum force in the
main boom pendants
exceeded
 The force actuating on the
main boom pendants has
exceeded the programmed
value

Reduce force acting on the
main boom pendants.
E84
Wrong rigging
condition.
 The selected rigging condition
is not contained in the crane
data file.

Select another rigging
condition
 Check the programming in the
crane data file.
E85
Error in the radius
determination
 The computed radius is too
small (negative deflection)

Check the programming in the
crane data file.
E88
Faulty main boom
position during luffing
jib operation
 During luffing jib operation
the main boom is not in the
prescribed angle range
 Angle measurement of main
boom defective.

Luff boom to the permitted
range
 Check angle measurement of
the main boom.
E89
Faulty positioning of
the jib during
operation with fixed
angle to the main
boom or to a luffing
jib
 During operation with fixed
jib to the main boom, the jib is
not in the permitted angle
range
 Angle measurement of the jib
defective

Luff the auxiliary jib to the
permitted range
 Verify angle measurement of
the auxiliary jib.
E94

from central unit to
console
 Can bus defective
 The system data transmission
defective

Restart system
 Check Can bus cable
