EMS Display Area
(1) Alert indicatorsThe Electronic Monitoring System (EMS) control notifies the operator of an immediate or impending problem with a machine system. Warning operation begins when the EMS control receives a signal that reflects an abnormal machine condition. The alternator and switches provide signals to the EMS control. The signals are:
An open switch. When a machine system condition exceeds the specified value of the switch, the switch opens.
An alternator "R" terminal signal which exceeds limits. The EMS control determines the limits.The EMS control analyzes the signals and activates the appropriate warning indication to notify the operator. The warning indications are:
FLASHING of an alert indicator
FLASHING of the action lamp
SOUNDING of the action alarm (ON and OFF)Note: To activate some warning indications more than one input is required. The EMS control decides when and what warning indications are activated.Abnormal machine system conditions are classified into three warning categories: 1, 2, and 3. The categories dictate the required response of the operator based on the severity of the condition. Warning category 1 represents the least severe condition and warning category 3 represents the most severe condition. The warning categories are identified for the operator according to the combination of warning indications that are active. See Warning Operation chart.
