Structure of the table
The columns “Measuring point“, “Unit", “Value" and “Kind of Alarm" in the tabular display mean:
Measuring point
Contains the designation of the measuring point
Unit
Contains the unit of the measurement variable
Value
Contains the current measured value
Min / Max
Identification of the type of monitoring of the limit value
Kind of Alarm
The three alarm stages: “Sensor failure", “Warning" or “Main alarm"
List of all measuring points
Each of the two engines has analogue and binary sensors. The measured values are monitored and evalu
ated by the MMDS diagnostic unit. The data is made available to the PC system via CAN BUS.
Identification of alarm monitoring
The following identifiers are distinguished at “Min / Max":
