Machine Security System Indicator (18) - This indicator illuminates red when the machine security system is activated.
Throttle Lock Indicator (19) - This indicator illuminates when the throttle lock is activated.
Left Turn Signal Indicator (20) - This indicator flashes when the left turn signal is operating.
Right Turn Signal Indicator (21) - This indicator flashes when the right turn signal is operating. Gauge Indicators
Engine RPM Gauge (5) - This gauge indicates the speed of the engine in revolutions per minute.
Torque Converter Oil Temperature Gauge (12) - The gauge indicates the temperature of the oil in the torque converter. If necessary, reduce the load that is on the truck until the oil temperature decreases. Reference See Operation and Maintenance Manual, "Troubleshooting - Engine" for possible causes of overheating.
Engine Coolant Temperature Gauge (17) - This gauge displays the temperature of the engine coolant. If the temperature rises into the red zone, the warning alarm will sound. Stop the truck in a safe place and investigate the cause. Do not operate the truck if the alarm continues to sound, or if the pointer is completely in the red zone. Truck operation during the sounding of the warning alarm may damage the engine. Stop the truck in a safe place and investigate the cause.
Brake Oil Temperature gauge (22) - This gauge displays the temperature of the brake oil.
Fuel Level gauge (23) - The fuel level gauge indicates the amount of fuel that remains in the fuel tank. LCD Digital Data Display
The LCD Digital Data Display window is used to show different sets of data which is important to the operator. The data on the Instrument Cluster display is present during machine operation. On trucks, this includes:
Vehicle Speed
Current Active Gear and Direction
Service Hour MeterWarning Operation
When a warning condition is present, indicators on the Instrument Cluster will inform the operator. These indicators follow the Caterpillar 3-level warning strategy. A Level-1 Warning concerns a problem for which service personnel needs to be informed, but the does not require immediate action by the operator. The appropriate system indicators (brake system - check indicator, power train system - check indicator, engine system - check indicator) will light red on the Instrument Cluster.A Level-2 Warning is a problem which requires the operator to change the operational behavior of the machine. The Action Lamp Indicator will illuminate red. The Action Lamp Indicator will also blink on and off.A Level-3 Warning is a problem that requires the operator to safely shut down the machine. The Action Lamp Indicator will blink on and off and the machine horn will sound in an on/off manner.Graphical Display Module (Messenger)
