WARNING

If the governed speed (maximum speed) is exceeded, lift off

accelerator pedal immediately and perform repair measures.

– If the values are not within specified range, a repair measure

must be made.

If the unit detects a valid throttle burst (the speed increases con‐

tinually during measuring period tx), the following is indicated on

display:
If the following is indicated on display:

n rpm        tB s  k 1/m  Gas T °C    M 
 XXX XXXX -.-   -.-     1     XX      -

The display remains “frozen” during the evaluation phase (ap‐

prox. 15 seconds).
After the evaluation phase, the display changes to:

n rpm        tB s  k 1/m  Gas T °C     M
 XXX XXXX  X.XX   X.XX     1     XX    -

The arrow pointing upwards indicates that the unit is waiting for

the next throttle burst.
Repeat test 4 times.
The following is indicated on display after each throttle burst:

n rpm        tB s  k 1/m  Gas T °C     M
 XXX XXXX X.XX   X.XX     X     XX    -

In this way, the unit measures and registers at least four throttle

bursts. After the fourth and for each further throttle burst se‐

quence, an average of the last three measurements is performed.
The following is indicated on display after each throttle burst:

n rpm        tB s  k 1/m  Gas T °C     M
 XXX XXXX X.XX   X.XX     X     XX    -

After 10 seconds, this display changes to:

             tB s  k 1/m  Band width   M
Average      X.XX   X.XX    X.XX       -

After 5 seconds, this display changes to:

             tB s  k 1/m  Band width   M
Average      X.XX   X.XX      XX       -

The display remains until a further throttle burst is performed or

another measurement is called up.
If the opacity figures are equal to or less than the prescribed fig‐

ures, cease measurements.
But if the determined opacity figures are over the prescribed fig‐

ures, locate fault during a repair measure
