Fault
code
Error Cause Elimination
E81
Too large difference of
the boom angles at tip
and base boom (if
avail.)
• The angle as to the horizontal
on the boom head exceeds the
main boom angle by more than
5 degrees.
• Check angle sensor on the
boom head.
• Check angle sensor on the
base boom.
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 luff-
ing 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 condi-
tion.
• The selected rigging condition
is not contained in the crane
data file.
• Select another rigging con-
dition
• 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 pre-
scribed 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.
E98
LMI watchdog acti-
vated
• LMI processing time limit
exceeded
• Reset system
• Connect PC terminal
and watch error mes-

EAB
Short circuit in the A2B
switch circuit
• Short circuit in the A2B
switch
• Short circuit in the cable to
the A2B switch
• Replace A2B switch
• Replace cable to the
A2B switch
EAC
A2B switch circuit
disconnected
• Disconnected cable in the
A2B switch
• Disconnected cable to the
A2B switch
• Connect or replace ca-
