B. FRONT BUZZER OPERATION
When all the above conditions are met, the front buzzer
sounds at short intervals if the difference between the cur-
rent and memorized engine rpms is over the standard.
C. STOPPING BUZZER OPERATION
If any of the below conditions is met, the buzzer stops.
• The difference between the current and the memorized
engine rpms is below the standard.
• The straw sensor is OFF for over 1 second.
• The neutral switch is ON.
• The reverse switch is ON.
• The threshing clutch is disengaged (threshing unit
switch: OFF).
• The engine rpm is below the speci fi ed value.
• The vehicle speed is below the speci fi ed value.
2.2.8 GRAIN SENSOR ALARM (ALARM
BUZZER, ETC.)
If straws or weeds are caught in the grain sensor during the
automatic depth control, the grain sensor S1 (straw side)
is OFF and the grain sensor S2 (grain side) is ON. That
means the error type 1 occurs during self-diagnosis. In this
case, the front buzzer sounds at short intervals. Also, the
LED of the MICOM unit displays "E" and "1" alternately. If
both grain sensors S1 (straw side) and S2 (grain side) are
ON during the automatic depth control, it means the error
type 2 occurs during self-diagnosis. In this case, the front
buzzer sounds at short intervals and the automatic feeding
lamp blinks. Also, the LED of the MICOM unit displays "E"
and "2" alternately.

2.2.9 CHECK LAMP (INSTRUMENT
PANEL)
The combine harvester is equipped with the self-diagnosis
function to detect malfunction among the sensors and
switches of the automatic systems.
When any malfunction is detected by this function, the
check lamp on the instrument panel blinks and the LED of
the MICOM unit displays a symbol corresponding to the
malfunction (see "6. Self-diagnosis").
