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":
D NORM Normal state
D XAExternal alarm
D FAULT Failure alarm
D TIAH Temperature limit value exceeded
D TIAL Temperature limit value undershot
D DTIAH Positive temperature deviation
D DTIAL Negative temperature deviation
D TAH Temperature too high (binary alarm)
D TAL Temperature too low (binary alarm)
D PIAH Pressure limit value exceeded
D PIAL Pressure limit value undershot
D DPIAH Positive pressure deviation
D DPIAL Negative pressure deviation
D PAH Pressure too high (binary alarm)
D PAL Pressure too low (binary alarm)
D LIAH Level limit value exceeded
D LIAL Level limit value undershot
D LAH Level too high (binary alarm)
D LAL Level too low (binary alarm)
D IND Display (analogue input, no limit value control, but failure display)
D BLC Blocked alarm (measuring point blocked by another measuring point)
