BRAKE GP-SERVICE & PARKING 2G5550 - Caterpillar

Your engine may not have the same gauges or all of the gauges that are described. For more information about the gauge package, see the literature that is from the OEM of the vessel.Gauges provide indications of engine performance. Ensure that the gauges are in good working order. Determine the normal operating range by observing the gauges over a period of time.Noticeable changes in gauge readings indicate a potential problem with a gauge or with the engine. Problems may also be indicated by gauge readings that change even if the readings are within specifications. Determine the cause of any significant change in the readings and/or correct the cause of any significant change in the readings. Consult your Caterpillar dealer for assistance.Caterpillar requires two lamps in addition to the gauge package that is normally provided. The "Diagnostic" lamp is yellow or amber. The "Diagnostic" lamp will communicate the status of the electronic system of the engine. The "Warning" lamp is red. This red "Warning" lamp warns the operator of engine problems. The following conditions are some examples of the problems:
low oil pressure
high coolant temperature
low coolant level
high inlet air temperature
Be ready to activate the engine shutoff manually, if there is no oil pressure . Damage to the engine will result if the engine continues to run without the correct oil pressure.
Engine Oil Pressure - This gauge indicates the engine oil pressure.A lower oil pressure reading is normal at low idle. If the load is stable and the gauge reading changes, perform the following procedure:
Remove the load.
Reduce engine speed to low idle.
Shut down the engine, and allow time for the oil to settle back into the engine oil pan.
Check the oil level. Maintain the oil level at the proper amount. The diagnostic lamp will turn on if the oil pressure drops below a safe range. A safe range for the oil pressure is determined by the engine protection package. The diagnostic code will be logged in the Engine Control Module (ECM).
Engine Oil Temperature - This gauge indicates the engine oil temperature. Maximum oil temperature at rated speed with a full load is 104°C (220°F).
Jacket Water Coolant Temperature - Typical temperature range is 87 to 98°C (189 to 208°F). The maximum allowable temperature with the pressurized cooling system is 102°C (216°F). Higher temperatures may occur under certain conditions. The water temperature reading may vary according to load. The reading should never exceed the boiling point for the pressurized system that is being used.If the engine is operating above the normal range and steam becomes apparent, perform the following procedure:
Reduce the load and the engine speed.
Inspect the cooling system for leaks.
Determine if the engine must be shut down immediately or if the engine can be cooled by reducing the load.
Tachometer - This gauge indicates engine speed. When the throttle control lever is moved to
