Structure Of The Table; Identification Of Alarm Monitoring - Man D2868 LE433 Operating Instructions Manual

Structure of the table

The columns "Measuring point", "Unit", "Value" and "Kind of Alarm" in the tabular display mean:
Measuring point
Unit
Value
Min / Max
Kind of 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)
Commissioning and operation
Contains the designation of the measuring point
Contains the unit of the measurement variable
Contains the current measured value
Identification of the type of monitoring of the limit value
The three alarm stages: "Sensor failure", "Warning" or "Main alarm"
