7.2 LMI System Malfunction Table (LMLG V 1.x)
Fault
code
Error Cause Elimination
E01
Lowered below radius
range or angle range
exceeded
• Fallen below the minimum
radius or gone past the maxi-
mum angle specified in the re-
spective load chart due to rais-
ing the boom too far
• Lower the boom to a ra-
dius or angle specified in
the load chart.
E02
Radius range ex-
ceeded or lowered
below angle range
• Gone past the maximum radius
or lowered below the minimum
angle specified in the respec-
tive load chart due to lowering
the boom too far
• Raise the boom to a radius
or angle specified in the
load chart.
• A non existing operating mode
has been selected
• Set the correct operating
mode for the operating state
in question
• The boom is in a non-permitted
slewing zone
• Slew the boom to a permit-
ted area.
E04
Operating mode not
acknowledged or non
permitted slewing zone
• The selected operating mode is
not available in the Flash-
EPROM or blocked
• Check the Data software in
the Flash-EPROM
• A non existing main boom
length has been selected
• Set the correct main boom
length for the operating
state in question
E05
Main boom length not
available
• The selected main boom length
is not available in the Flash-
EPROM or blocked
• Check the Data software in
the Flash-EPROM
E06
Radius range ex-
ceeded or lowered
below angle range with
luffing jib operation
• Maximum radius as specified in
the load chart exceeded or low-
ered below minimum angle due
to lowering the luffing jib too far
• Raise the jib to a radius or
angle specified in the load
chart.
E07
Overload relays check
• Relays = overload active and
CU input 20 = on
• Relays = no overload and CU
input 20 = off
• Check cable to overload
relays and CU input 20
• Check relays
• Check CU input 20
• Cable between the central unit
and the force transducer defec-
tive or loose. Water inside the
plug of the transducer
• Force transducer defective
• Check cable as well as
plugs, replace, if need be
• Replace force transducer
E14
Below lower limit value
in measuring channel
"force main boom right"
• Electronic component in the
measuring channel is defective.
• Replace sensor unit
• Cable between the central unit
and the angle sensor defective
or loose. Water inside the plug
of the angle sensor
• Angle potentiometer defective
• Check cable as well as
plugs, replace, if need be.
• Replace angle sensor
E15
Below lower limit value
in measuring channel
"angle main boom"
• Electronic component in the
measuring channel defective.
• Replace sensor unit
E16
Below lower limit value
in measuring channel
"angle luffing jib"
• Refer to E15
• Refer to E15
E17
Below lower limit value
in measuring channel
"force luffing jib left"
• Refer to E14 • Refer to E14
