9.5 Detector abnormality 9.5.1 Stop processing at detector abnormality (compulsory unload output) When a failure occurs with a detector that is needed to calculate the moment load ratio (load ratio) (error code Nos. of 1000s and 2000s), the automatic stop cannot be performed by the "re-stop condition." Therefore, in the AML cancel status at detector abnormality, all the stop functions are canceled. However, when the detector needed for stop function is working normally, the relevant automatic stop function is enabled (only the ones canceling is not allowed). The list of necessary detectors for automatic stop functions is shown in the table below. When a detector abnormality exists, compulsory unload is always performed due to the abnormality status but not by an operation. However, the slewing operation shall be permitted. Table 9.5.1 Relationship between detector abnormality and automatic stop function (including items that are not applicable depending on models) (1/3) Stop item Stop condition Do output control 100% lifting performance stop
