Working of the MFA master instrument
The LHS instrument
With “ignition on” the driving speed appears in the top line of the display of the LHS master
instrument and the total number of kilometres driven in the bottom line.
The RHS instrument
With “ignition on” the engine speed appears in the top line of the display of the RHS master
instrument and the total number of operating hours in the bottom line. To display a different value,
for instance the engine temperature, simply press the “engine temperature” symbol and the current
value will appear in the display. This reading will remain visible until the function key is pressed
again.
If a
critical value is exceeded (e.g. engine temperature 98°C) the MFA will automatically warn
you. The critical value starts flashing in the display and the built-in buzzer will emit an intermittent
acoustic signal (
pre-warning ). The related function key lamp (in this example the engine
temperature) will light up and flash. You can then accept this pre-warning by pressing the
appropriate function key (in this example the engine temperature). The buzzer will stop.
If an
alarm value is exceeded (e.g. engine temperature 103°C) the MFA will immediately alarm
you ( alarm ). Similar to the situation described above the alarm value will appear in the display and
flash and the related function key will light up. In this situation the buzzer will emit a continuous
signal. The fact that the alarm value has been exceeded will be recorded in the diagnostic memory
of the MFA.
