EXHAUST AS-OLT 5088430 - Caterpillar

The following is the recommended action for the machine operator in response to the different warning levels:Level 1 - The alert indicator for the system that is involved will illuminate. A Level (1) warning will indicate that the operator should be aware of a condition of one or more of the machine systems.Level 2 - The operation of the machine should be changed or maintenance should be performed to the machine. Possible damage to components on the machine may occur.Level 2S - Utilized in a transmission overspeed event. In addition to the normal Level (2) cluster warning, the audible alarm will be in a constant ON state.Level 3 - Level (3) indicates the need for an immediate, safe emergency engine shutdown. Possible injury to the operator or severe damage to components may occur.
