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)
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.
Slewing angle detector 1 trouble E2017
Although the slewing dead angle detection is OFF, the slewing angle detector 1 output is in the ON range of slewing dead angle detection. Abnormality is detected only when the slewing dead angle detection is available. Normal range: Set with by-models data
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.
Slewing angle detector 2 trouble E2019
Although the slewing dead angle detection is ON, the slewing angle detector 2 output is in the OFF range of slewing dead angle detection. Abnormality is detected only when the slewing dead angle detection is available. Normal range: Set with by-models data
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.
E2021
Slewing angle detector offset trouble
Slewing 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)
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.
E2022
Boom telescoping cylinder length detector trouble
The detection value of the telescoping cylinder length detector is out of the normal range. Normal range: 0.25 to 4.75 V
Cause: Detector malfunction, signal line open/short circuit, board malfunction Moment trouble E2023
Load calculation value is negative. When the civil engineering input Di is "During civil engineering work," the abnormality will not be judged.
Cause: Detector malfunction, signal line open circuit, board malfunction Remedy: Perform inspection for the above possible cause.
E2030
Elevating rod pressure trouble
The detection value of elevating cylinder's rod side pressure detector is out of the normal range, and the status continues for 5 seconds in low pressure side or for 1 second in high pressure side. Normal range: 4 to 95% (0.20 to 4.75 V)
Cause: Detector malfunction, signal line open circuit, board malfunction Remedy: Perform inspection for the above possible cause.
