Name

Abnormal moment [Distortion detection type] Does not stop.

Abnormal moment [Hydraulic pressure detection type]

Cannot operate toward the critical side. This alarm is triggered when the actual load value calculated inside the AML shows a negative value. Abnormal negative load value range varies depending on the boom status.

Status: The actual load value calculated inside the AML shows a negative value due to abnormal moment detector. Therefore, re-adjustment of the detector is required. (Error code 0067: The alarm is triggered without automatic stop, error code 0113: The machine stopped by an operation toward the critical side.)

Cause: Detector is abnormal. (Abnormal boom length detector, boom angle detector, moment detector, or elevating cylinder pressure detector)

Detector is incorrectly adjusted.

AML main unit is abnormal. (Analog board is faulty.)

The moment value cannot be detected correctly because the elevating cylinder has retracted to the boom lowering stroke end. (In case of error code 0113)

Action: Readjust the corresponding detector. Investigate the detector which seems to be faulty. The input status from a detector can be checked in "Ai Check" item of the "Maintenance" menu or "Elevation Cylinder Oil Pressure Monitor." In "Ai Check," if it is normal, "ok" is displayed. ([Ai Check] related items: [ブーム L], [ブームカク], [モーメント V], [キフクノビ], [キ フクチヂミ], etc.)

For the specifications of the detector, refer to the "Detector Check" in the INFORMATION AND DATA section.

Raise the boom. (In case of error code 0113)

Name

キフク ストロークエンドデス Elevation stopped at stroke end

Displayed only for [Hydraulic pressure detection type].

Status: The boom reaches the upper stroke end. (The boom has been elevated to the available limit.) The machine automatically stops because an operation toward the critical side is attempted in this situation.

Cause: When the moment is detected in the hydraulic pressure in the elevating cylinder, the correct moment cannot be detected if the boom elevating cylinder reaches the stroke end. Therefore, the automatic stop function intervenes in the boom elevating operation just before the boom elevating cylinder reaches the stroke end.

Action: Stop the operation which has caused the stop. Operate the boom in the opposite direction which has caused the stop.
