Warning Categories

The Caterpillar Monitoring System provides three warning categories. The first category requires only operator awareness. The second warning category requires an operator response. The third warning category requires immediate shutdown of the machine.

Table 1
WARNING OPERATION    
Warning Category     Warning Indications  (1)     Action     Possible Result  (2)    
Flashing Alert Indicator Flashing Action Lamp     Action Alarm    
1                 No immediate action is required. The system needs attention soon.     No damage will occur to the machine. Minor reductions in machine performance may occur.    
2     X     X         Change machine operation or perform maintenance to the system.     Severe damage to components can occur.    
2S     X     X     X  (3)     Change machine operation or perform maintenance to the system.     Severe damage to components can occur.    
3     X     X     X  (4)     Immediately perform a safe engine shutdown.     Injury to the operator or severe damage to components can occur.    
( 1 ) The active warning indications are marked with an X.
( 2 ) This is the possible result, if the operator takes no action.
( 3 ) A steady alarm sounds.
( 4 ) A pulsating action alarm sounds.

Functional Test

The Caterpillar Monitoring System performs an automatic internal test when the machine is activated. Turning the engine start switch from the OFF position to the ON position will activate the test.

The test verifies proper operation of the outputs (displays, indicator lamps, and audible alarms).

The internal circuits are automatically checked.

The operator must observe the outputs in order to determine whether the displays are operating properly. The length of time for the test is approximately 3 seconds.

During this test, the alert indicators flash, the gauges will sweep, the Cat logo will display, and the operator profile selection will display. Also, the display window shows the following information:

  • All units of measurement (degrees, pressure, distance, rotational speed, and volume)

  • "X10" indicator

  • Symbol for hour meter

  • "8.8.8.X.8.8." on the digital readout

The tachometer and the gauge needles ramp straight up. Then, the gauge needles go to the right and to the left. The gauge needles then go to the final position.

  • The gear/direction readout shows an asterisk.

  • The digital speedometer shows "188" mph and km/h.

  • The indicator lamp is on continuously.

  • The audible alarm sounds once.

The display then goes into the Normal Mode of operation.
