A view of the operator panel display area.
(1) Gauge cluster
(2) "VIMS" display monitor The software will delay most of the maintenance events from being displayed. The "VIMS" ECM will wait up to eight seconds from the start of an event before the event is displayed. This delay is called debounce. This eight second delay is included in the “total duration time” of the events that are recorded in the event list. When "VIMS" ECM has received an event from an electronic control via the "Cat Data Link" the "VIMS" ECM adds zero time to these events. The "VIMS" ECM displays the events immediately. Debounce is applied to many parameters in order to prevent “false tripping” of events or debounce is applied to many parameters in order to reduce “false tripping” of events. ACTIVE maintenance events are shown in message area (10). A maintenance event is specified by showing that a parameter has an “ERR” and instructions for the operator such as “CALL SHOP”. When multiple ACTIVE maintenance events are present each event will be displayed on the message area. The message area scrolls through the events at three second intervals. The following display is shown when the engine oil pressure circuit has an error:
