MMDS CLC 6.5 colour display on the control stand
If a value reaches a critical level, a warning mes
sage or an alarm is tripped and shown on the dis
play, depending on importance. If the value ex
ceeds certain plausible limits, a sensor fault is
displayed. An integrated buzzer emits a warning
sound each time a new alarm message is issued.
This sound can be stopped at the push of a button.
A separate alarm table lists all pending alarms with
detailed information. Examples of alarms are
shown on the illustration opposite.
The system makes a distinction between:
S Alarm, e.g. EDC combined fault, red, 3100 SPN
S Warning, e.g. SFFR combined fault, orange,
4022 SPN
S Sensor fault, e.g. gearbox oil pressure, yellow
The "SPN numbers", see "Value" column in table
opposite, are used by MAN Service to identify the
fault.
