3. Erasing the Overload History
[NOTICE]
When the AML main unit or EEPROM is replaced for repair and all adjustment is completed, erase-protect the overload history. Before delivering the machine to an user, erase-protect the overload history by erasing the latest history data three times.
You can erase the overload history data (record of crane operation when moment load ratio exceeds the set limit). Note that if the latest history data are erased three times, the menu will not appear, disabling the history data to be erased. At the time of the third erasure, the records of the greatest overload values will also be erased.

Error Message
1. Display of Error Message [NOTICE]
The language (English or Japanese) of error message is selected at the [ï Language] menu in the adjustment mode.
2. How to Read the Error Message
1. Error code in the error message is represented by four-digit codes.
Error code: E1 E2 E3 E4 lndividual code
Group code
0:Alarm
1:Abnormal communication
2:Abnormal detector
3:Abnormality inside AML
2. The highest rank (E1 in the above figure) indicates error groups. The each next three digit figure (E2 through E4 above) indicates individual error code under error groups.
1. If AML system detects the trouble in ordinary use (user mode), it makes beep sound as well as displays error message on the moment display. Display example: [Error:2001]
Shows that an error of error code 2001 has occurred.
2. This error message display continues till the cause is eliminated.
3. While the adjustment or maintenance mode is being used, only beep sound informs the operator of the occurrence of trouble. The display on the moment display, however, does not change to the error message display automatically. Current message keeps displayed.
4. To confirm the error message in the adjustment or maintenance mode, press the lift height limit key. While you are pressing the key, the error message is shown on the moment display. (It may take some seconds for the display to change.)
5. If trouble remains even when you return to the user mode after exiting adjustment or maintenance mode, corresponding error message appears on the moment display.
3. Since group code ì0î indicates a warning condition, it does not always mean that there is a problem in the system when an error message is displayed.
4. For this reason, warning-related error messages are not registered in the systemís error history memory. Warning-related error messages are shown in the moment display in the same way as message for other group codes.
3. How to Read the Error History
1. Error history records 50 errors, maximum, of the group code, in order of occurrence. Those beyond 50 will be made to disappear in the order of occurrence.
2. See the ìError Data Displayî in the ìFunctions of and How to Use Maintenance Modeî section for reading the error history.

Abnormal moment [Strain gauge detector] Does not stop
Abnormal moment [Pressure sensor detector] Can not operate to dangerous direction
Situation: Actual lifting load display value calculated in the AML becomes a minus value because of an abnormal moment detector. Therefore, re-adjustment of the moment detector is required.
(0067: Only warning, automatic stop does not work)

[Warning : 0113] Moment value can not be detected because the elevating cylinder has retracted to the stroke end.
* This warning (0113) is output when actual lifting load display value that calculate in the AML becomes a minus value. Abnormal minus load value is difference due to the boom condition.
Action: Readjust the corresponding detector (pressure sensor). Investigate the detector which seems to be defective. Input status from the detector can be confirmed by ìAiî check of ìMaintenanceî menu and ìElevating cylinder pressure monitorî.
(ìAiî check related items: [Boom L], [Boom A], [MMT V], [DRC EXT], [DRC RTR] etc.)
Raise the boom. (error code: In case of 0113)

Warning : 0081 Elevation motion slowing down
* This error code is applicable only to models with the slow elevation stop function.
Situation: The boom elevation slow stop function is activated, slowing down boom elevation motion.
Cause: The boom has been elevated close to a stop angle (100% stop, restriction limit stop, stroke end stop, or rear stability stop), and the elevation slow stop function has been activated, and the elevation speed is reduced. (The error code is displayed only when the boom is being elevated)
Action: Stop operating the boom.
Operate the boom in the opposite direction, whether it is rising or lowering. Cancel the boom angle limit restriction function. Move the boom to the non-critical side.
Message Description
Warning : 0082 Swing motion slowing down
* This error code is applicable only to models with the slow swing stop function.
Situation: The slow swing stop function is activated, slowing down boom swing motion.
Cause: The boom has swung close to a stop angle (either 100% stop or range limit stop) and the slow swing stop function has been activated, and swing speed is reduced. (The error code is displayed only when the boom is being swung to the left or right)
Action: Stop the swing operation. Swing away from the limit.
Retract or raise the boom so that the lifting capacity will not be exceeded. Cancel the swing limit restriction function.

Message Description
Warning : 0085 Elevation stopped at stroke end
* Applicable to the models with the oil pressure detection method.
Situation: Crane operation is automatically stopped when operation toward a critical condition is attempted while boom elevating operation is stopped due to elevation stroke end.
Cause: Boom elevating is automatically stopped just before the elevating cylinder stroke end because the moment cannot be detected correctly by the oil pressure in the elevating cylinder if the cylinder is reached/extended to stroke end.
Action: Stop operation which has caused automatic stop. Operate the boom in the opposite direction which has caused automatic stop.
Message Description
Warning : 0088 Stopped at jib limit
* This error code is applicable only to models with jib extension status monitoring.

Precautions for adjustment
(*1) Adjust the center of dispersion to coincide to the adjusting value.
(*2) Adjust the boom angle and the moment in the elevating lowering operation.
(*3) Adjust the swing angle in the clockwise swing operation.
(*4) When adjusting the moment, make the number of parts of line to the standard number (four parts of line) that is when boom fully extended, and set the AML as Boom status: Boom and Number of parts of line:4.
