( 1 ) The active warning indications are marked with an X.
( 2 ) The possible result if no operator action is taken.
( 3 ) The alert indicator flashes at a 10 Hz rate.
( 4 ) The action lamp flashes at a 1 Hz rate (1 second ON, 1 second OFF).

Warning operations are activated when the VIDS ECM detects a problem with a signal. The "problem signal" reflects an abnormal condition of the machine ("machine events"). Warning operations are also activated when the VIDS ECM detects a problem with the control system ("system event"). The VIDS ECM receives data from the following components: Switches, sensors and other electronic control modules. The "problem signals" are listed below:
Wh n 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.
Abnormal sensor signals that are detected by the VIDS ECM.The VIDS ECM analyzes these "problem signals". The VIDS ECM then notifies the operator by activating the appropriate warning indications on the display components. The warning indications are listed below:
FLASHING of the alert indicator on the message center. ("The alert indicator flashes approximately ten times per second.")
The action lamp FLASHES. ("The action lamp ON one second and OFF one second.")
The action alarm is SOUNDED. ("The action alarm is turned ON for one second and turned OFF for one second.")Note: More than one input is required in order to activate some warning indications. The warning indication that is activated is determined by the VIDS ECM. Data events and maintenance events are classified into multiple warning categories. There are three warning categories that
