The monitoring system alerts the operator of a problem or of an impending problem. The panel is designed to alert the operator of faulty machine systems.
Illustration 1 | g01041785 |
Check the operation of the monitoring system. Observe the self-adjusting and the testing procedure when you start the engine.
The self testing feature verifies that the modules of the monitoring system are properly operating. The self testing feature verifies that the display module is properly operating.
The internal circuits are automatically checked. The outputs (display, action light, and the action alarm) are automatically checked.
The operator must observe the outputs in order to determine if the modules are operating properly. This self testing feature is three seconds long.
Reference: For more information, refer to Systems Operation, RENR2014, "AVSpare Monitoring System for Track-Type Tractors".
The monitoring system provides three warning categories. The first category requires only operator awareness. The second category requires the operator to respond to the warning. The third category requires immediate shutdown of the machine systems.
In category 1, only the alert indicator will flash. This category alerts the operator that the machine system needs attention.
Fuel Level (2) - When the fuel level reaches ten percent of the tank capacity, this indicator will illuminate. Refuel within an hour in order to avoid running out of fuel. |
Air Inlet Heater (4) (AIH) - This indicator indicates that the AIH is active. If the ECM determines that the AIH is needed, the indicator will light prior to engine start-up. If the ECM determines that the AIH is needed, the indicator will light after starting. Also, the light may cycle on and off for as long as 13 minutes after starting. |
Electrical System (5) - This panel indicates a malfunction in the electrical system. If this alert indicator flashes, the system voltage is too high or too low for machine operation. |
Increase the engine speed to high idle, if the electrical loads are high. The electric loads consist of the air conditioning and/or the lighting. An alternator will generate more output when the engine is at high idle. If the alert indicator for the electrical system stops within one minute, the electrical system is operating normally. During the periods of low engine speeds, the alternator is overloaded.
Modify the operating cycle. This will prevent the electrical system from overloading. This will also prevent the electrical system from discharging the batteries. You can also reduce the loads on the electrical system. Use the medium fan speed in the cab instead of the high fan speed.
Run the engine speed at normal rpm. Run the electrical system at a light load. If the light remains on, drive the machine to a convenient stop. Investigate the cause of the problem. The cause may be a loose alternator belt, a broken alternator belt, a faulty battery, a faulty alternator, etc.
Parking Brake (14) - This indicator indicates that the parking brake is engaged. If this indicator flashes, disengage the parking brake. |
Do not operate the machine until the cause of the problem has been corrected.
In this category, the alert indicator flashes and action light (1) flashes. The warning category requires you to change the machine operation. Changing the machine operation will reduce the excessive temperature in one of the systems or in more than one of the systems. Also, changing the machine operation will reduce the excessive engine speed.
If the alert indicator continues to flash, do not operate the machine. If the action light continues to flash, do not operate the machine.
Transmission Oil Filter (7) - This indicator indicates that the transmission oil filter should be changed. If this alert indicator flashes, change the transmission oil filter. Refer to Operation and Maintenance Manual, "Transmission Oil Filter - Replace". |
Steering System (10) - This indicator indicates that a problem exists in the electronics of the steering system. If this indicator continues to flash, reduce the load on the machine. Check the system at the earliest possible time. |
Brake System (11) - This indicator indicates that a problem exists in the electronics of the brake system. If the indicator continues to flash, reduce the load on the machine. Check the system at the earliest possible time. |
Transmission System (12) - This indicator indicates that a problem exists in the electronic system of the transmission. If the indicator continues to flash, reduce the load on the machine. Check the system at the earliest possible time. |
Engine System (13) - This indicator indicates that a problem exists in the electronics of the engine system. If the machine is operating and the indicator flashes, stop the machine immediately. Stop the engine and Investigate the cause of the problem. |
Parking Brake (14) - This indicator indicates that the parking brake is engaged. If the machine is operating and the indicator flashes, pull the machine to a convenient stop. Investigate the cause of the problem. |
In this category, the alert indicator lights and action light (1) flashes. Also, the action alarm will sound. This category requires immediate shutdown of the operation in order to prevent severe damage to the system and/or to the machine.
Do not operate the machine until the cause has been corrected.
Engine Coolant Level (3) - This indicator indicates low engine coolant. This indicator will remain on for only thirty seconds during the engine starting procedure if the coolant level is below the minimum. This indicator also flashes at engine start-up. If this indicator flashes during normal operation, stop the machine immediately. Stop the engine and investigate the cause. |
Transmission Oil Temperature (6) - This indicator indicates excessive transmission oil temperature. If this indicator flashes, stop the machine immediately. Stop the engine and investigate the cause. |
Engine Oil Pressure (8) - This indicator indicates low engine oil pressure. If this indicator flashes, stop the machine immediately. Stop the engine and investigate the cause. |
Fuel Pressure (9) - This indicator indicates low fuel pressure. If this indicator flashes, stop the machine immediately. Stop the engine and investigate the cause. |
