Warning Categories
Problems from the machine system are classified into three warning categories. The categories are based on the severity of the problem. The categories also dictate the required response of the operator. Warning Category 1 represents the least severe problem and Warning Category 3 represents the most severe problem. The warning categories are identified for the operator according to the combination of warning indications that are active. See Table 1 for Warning Operation. Note: See the Operation and Maintenance Manual for complete information on the Warning Operation.
