The Caterpillar Instrument Cluster notifies the operator of an immediate problem with a machine system or an impending problem with a machine system. Warning operation begins when the main display module receives a problem signal. The problem signal reflects an abnormal condition of the machine. Warning operation also begins when the main display module detects a problem with the control system. The problem signals are the following conditions:
Open switch - When a condition exceeds the trip point of the switch, the switch opens.
Abnormal condition that is detected by the electronic control module - The abnormal condition is then communicated over the Cat Data Link to the main display module.
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 the Table 1 for Warning Operation.
The main display module analyzes the problem signals. To notify the operator of a warning, the display components of the main display module activate appropriate warning indications on the Instrument Cluster. The following warning indications will notify the operator:
Level 1 - The action lamp illuminates solid amber.
Level 2 - The action lamp flashes red in color and the action alarm does not emit a sound.
Level 3 - The action lamp flashes red in color and the action alarm emits a pulsating sound.
