Error name Description
Crane
operation
Left front outrigger
length detector
trouble
The detection value of front left outrigger length detector is out of the
normal range.
Normal range: 5 to 95% (0.25 to 4.75 V)
¯
E2011
Cause: Detector malfunction, signal line open/short circuit, board malfunction
Remedy: Perform inspection for the above possible cause. The status of any input from the detector
can be checked using the “Ai check” function from the “Maintenance” menu.
Left rear outrigger
length detector
trouble
The detection value of rear left outrigger length detector is out of the
normal range.
Normal range: 5 to 95% (0.25 to 4.75 V)
¯
E2012
Cause: Detector malfunction, signal line open/short circuit, board malfunction
Remedy: Perform inspection for the above possible cause. The status of any input from the detector
can be checked using the “Ai check” function from the “Maintenance” menu.
Swing angle detector
1 trouble
(swing dead angle
switch OFF)
Although the swing dead angle detection is OFF, the swing angle
detector 1 output is in the ON range of swing dead angle detection.
Abnormality is detected only when the swing dead angle detection is
available.
Normal range: Set with by-models data #207
¯
E2017
Cause: Detector malfunction, signal line open/short circuit, board malfunction
Remedy: Perform inspection for the above possible cause. The status of any input from the detector
can be checked using the “Ai & Di check” function from the “Maintenance” menu.
Swing angle detector
2 trouble
(swing dead angle
switch ON)
(same as swing
angle detector 1,2
select switch)
Although the swing dead angle detection is ON, the swing angle
detector 2 output is in the OFF range of swing dead angle detection.
Abnormality is detected only when the swing dead angle detection is
available.
Normal range: Set with by-models data #271
¯
E2019
Cause: Detector malfunction, signal line open/short circuit, board malfunction
Remedy: Perform inspection for the above possible cause. The status of any input from the detector
can be checked using the “Ai & Di check” function from the “Maintenance” menu.
Swing angle detector
offset trouble
Swing angle detector 1 and 2 are mounted with 180° positional
difference, and the difference has deviated from the normal range.
Normal range: Voltage output difference between detectors is 48.6
to 54.3%. (Set with by-models data #272)
¯
E2021
Cause: Detector malfunction, signal line open/short circuit, board malfunction
Remedy: Perform inspection for the above possible cause. The status of any input from the detector
can be checked using the “Ai check” function from the “Maintenance” menu.
Moment abnormality
Load calculation value is negative.
When the civil engineering input Di (No. 17206-34) is "During civil
engineering work," the abnormality will not be judged.
¯
E2023
Cause: Detector malfunction, signal line open circuit, board malfunction
Remedy: Perform inspection for the above possible cause.
