OPERATION
Warning Category Warning Indications (1) "Operator Action Required" "Possible Result "(2)
"Alert Indicator Flashes "(3) "Action Lamp Flashes"(4) "Action Alarm Sounds "
1 X No immediate action is required. The system needs attention soon. No harmful effects or no damaging effects.
2 X X (4) Change machine operation or perform maintenance to the system. Severe damage to components can occur.
2-S X X (4) X (5) Immediately change the machine operation. Severe damage to machine components
3 X X (4) X (6) 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 no action is taken by the operator.
(3) The alert indicator flashes at a 8 Hz rate.
(4) The action lamp flashes at a 1 Hz rate. This means that the lamp is ON for 1 second and the lamp is OFF for 1 second.
(5) Steady
(6) The action alarm sounds at a 1 Hz rate. This means that the alarm is ON for 1 second and the alarm is OFF for 1 second.

(11) Gauge warning area The operator will be warned of immediate problems with a machine system or impending problems with a machine system by VIMS. Warning operations are activated when the VIMS electronic control module detects a problem with a signal. The “problem signal” reflects an abnormal condition of the machine (“data events”). Warning operations are also activated when the VIMS electronic control module detects a problem with the control system (“maintenance/diagnostic events”). Switches, sensors and other electronic control modules send electronic signals to the VIMS electronic control module. 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 VIMS electronic control moduleThe VIMS electronic control module analyzes the “problem signals”. The main module then notifies the operator by activating the appropriate warning indications on the display components. The warning indications are listed here:
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 for category 3 and the action alarm is turned on countinuously 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 main module. Data events and maintenance events are classified into multiple warning categories. There are four warning categories that are shown to the operator. The categories are based on the severity of the problem
