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.
