Message Center Module (7) Alert Indicators. (8) Display Area.The monitoring system notifies the operator of an immediate problem or an impending problem with a machine system. The warning operation begins when the monitoring system receives a signal that has a problem that reflects an abnormal machine condition. The monitoring system also detects a problem in the control system. The following list contains some of the components that provide signals to the monitoring system: switches, sensors and electronic control modules. There are other components that also provide signals to the monitoring system. The signals that are problems are listed below:
An open switch opens when a condition exceeds the trip point of the switch.
A sensor signal is out of the normal operating range. The main module determines the limits.The monitoring system analyzes the problem of the signals. The monitoring system informs the display components. The display components activate the appropriate warning indication in order to notify the operator. The warning indications are listed below:
The alert indicator FLASHES approximately nine times per second.
The action lamp FLASHES ON one second then OFF one second.
The action alarm SOUNDS ON one second then OFF one second.Note: More than one input is required to activate some warning indications. The monitoring system decides when the warning indicators are activated. The monitoring system determines the warning indications that are activated. Data events and maintenance events are classified into multiple warning categories. Three of the warning indications are shown to the operator. The warning categories are based on the severity of the problem. The severity of the problem will dictate the required response of the operator. Warning category 1 represents the least severe problem. Warning category 3 represents the most severe problem. The warning categories are identified for the operator according
