R2900 Load Haul Dump Gauges Caterpillar


Gauges
`

The CMS gauge displays are vacuum fluorescent displays located in the dash panel.




Illustration 1g00914753

Should there be a fault between the ECM and the CMS, the following can be observed on the CMS display:

  • The oil pressure gauge (1) will flash.

  • The coolant temperature gauge (2) will flash.

  • The tachometer (7) will flash and a digital reading of 3000 RPM will be displayed.

  • The coolant level indicator (6) will flash.


Engine Oil Pressure (1) - Indicates the oil pressure in the engine. GREEN RANGE is the normal operating pressure. RED RANGE is low oil pressure.


Engine Coolant Temperature (2) - Indicates the temperature of the engine coolant. GREEN RANGE is the normal operating temperature. RED RANGE is excessive engine coolant temperature.


Transmission Oil Temperature (3) - Indicates the temperature of the transmission/torque converter oil. GREEN RANGE is the normal operating temperature. RED RANGE is excessive oil temperature.


Hydraulic Oil Temperature (4) - Indicates the temperature of the hydraulic oil. GREEN RANGE is the normal operating temperature. RED RANGE is excessive oil temperature.


Fuel Level (5) - Shows the amount of fuel in the fuel tank.

Tachometer (7) - The tachometer displays the engine rpm in a digital read-out during operation.

Speedometer (8) - The speedometer displays the machine ground speed in a gauge display during operation.

Actual Gear Indicator (9) - The actual gear indicator consists of two digits. The two digits indicate the actual transmission gear that is engaged. The left digit is the actual gear. The right digit shows the direction that was selected.

Service Code (10) - During machine operation, if this indicator comes on, the CMS control has detected and stored information regarding abnormal electrical conditions in CMS circuits (inputs or outputs) or in a power train control circuit.

Diagnostic information is available in the service mode for service personnel.

Reference: For more information, refer to Systems Operation, Testing and Adjusting, "Computerized Monitoring System with Vacuum Fluorescent Display" for the machine that is being serviced.

Reference: For information on transmission control faults, refer to the Systems Operation, Testing and Adjusting, "Electronic Transmission Control System" for the machine that is being serviced.

Exhaust Back Pressure Gauge (11) (If Equipped) - Indicates the exhaust back pressure. When the gauge reads above 6 kPa (25 inch of H2O) the exhaust purifilter must be cleaned.

Illustration 5g00937415

Rear Brake Oil Pressure Gauge (12) (If Equipped) - Shows the hydraulic pressure in the rear braking circuit when the service brakes are fully applied. The rear brake oil pressure should be 4140 ± 345 kPa (600 ± 50 psi).




Illustration 6g00937414

Front Brake Oil Pressure Gauge (13) (If Equipped) - Shows the hydraulic pressure in the front braking circuit when the service brakes are fully applied. The front brake oil pressure should be 4140 ± 345 kPa (600 ± 50 psi).


NOTICE

Loss of brake oil pressure may decrease the brake application force. Also, loss of brake oil pressure may cause the parking brake to engage. If low brake oil pressure is indicated, stop the machine immediately. Inspect the system for the cause of low brake oil pressure. Repair the brake system before returning the machine to operation.

Service Hour Meter (14) - Indicates the total operating hours of the engine. It should be used to determine service hour maintenance intervals.
