| (1) | The active warning indications are marked with an X. |
| (2) | The possible result if no action is taken by the operator. |
| (3) | The alert indicator flashes at a 1 Hz rate. This means that the lamp is ON for 1/2 second and the lamp is OFF for 1/2 second. |
| (4) | The action lamp flashes at a 1 Hz rate. This means that the lamp is ON for 1/2 second and the lamp is OFF for 1/2 second. |
| (5) | Constant Alarm. |
| (6) | The action alarm sounds at a 1 Hz rate. This means that the alarm is ON for 1/2 second and the alarm is OFF for 1/2 second. |
The Machine ECMs will warn the operator of immediate problems with a machine system or impending problems with a machine system.
Warning operations are activated when the Machine ECMs detect a problem with a signal. The “problem signal” reflects an abnormal condition of the machine (data events). Warning operations are also activated when the Machine ECMs detect a problem with the control system (maintenance/diagnostic events). Switches, sensors and other electronic control modules send electronic signals to the Machine ECMs. The problem signals are listed here:
- When a condition exceeds the trip point of the switch, the switch opens.
- When a condition exceeds the trip point of the switch, the switch closes.
- Any abnormal sensor signal that is detected by the Machine ECMs.
The Machine ECMs analyze the problem signals. The appropriate ECM then notifies the operator by activating the appropriate warning indications on the Advisor module. The warning devices for the Advisor are listed below:
- The action lamp FLASHES (ON one half second and OFF one half second).
- The action alarm is SOUNDED (ON for one half second and turned OFF for one half second for category 3, ON continuously for category 2-S).
Note: More than one input is required in order to activate some warning indications. The warning indications that are activated will be determined by the appropriate ECM.
Data events and maintenance events are classified into multiple warning categories. There are four warning categories that are shown to the operator. These categories are based on the severity of the problem which dictates the response that is required by the operator. Warning category 1 represents the least severe problem and warning category 3 represents the most severe problem.
The warning categories are identified for the operator according to the combination of warning indications that are active. Refer to table 1. When multiple events are present, the message area will scroll through all the events in three second intervals. When a category 3 event is active, scrolling through the category 1 and 2 events is not permitted.
The warning category of an event may be raised to a higher category automatically. Event duration is used in order to determine if a change in the category is necessary. An example of an event that would require a category change: The category 2 warning for the transmission lube temperature changes to a category 3 warning after 150 seconds.
When a category 1 or category 2 event occurs, the operator may acknowledge the event. The operator acknowledges the events by pressing the "OK" button on the Advisor. The following information is recorded in the event list for each event:
- Time of occurrence
- The number times the event was acknowledged
- The machine location (with Product Link equipped)
After an event is acknowledged, the warning indications may disappear for a specified time period. The warning indications will reappear for an event that is still active after the time period elapses. These warnings may be acknowledged again.
The Category 2-S is a conventional Category 2 with a continuous action alarm. A Category 2 that is considered to be a severe condition will cause a category 2-S to be logged. A Category 2 tells the operator to change machine operation in order to correct the warning condition. The operator is instructed to IMMEDIATELY change operation of the machine that relates to certain Category 2-S events.
Note: Most category 3 events cannot be acknowledged by the operator.
