The determination of the maximum shaft speeds is
basedona5seconds measuring period.
This period starts when:
- after ignition, the engine runs for the first time
at full throttle with the threshing mechanism
engaged, or
- each time the engine runs at full throttle with
the threshing mechanism engaged and pres-
sing the
key of the Infoview monitor.
This speed determination has to be performed each
time the threshing drum and/or cleaning fan
speed has been changed.
All warning lights will blink as long as the automatic
maximum shaft speed level determination is in opera-
tion (5 seconds).
If the combine is equipped with a straw chopper and
the chopper is off during the automatic maximum
shaft speed level determination, then the maximum
speed of the straw chopper is determined the first
time the chopper is engaged and the engine runs at
full throttle.
If a warning light starts to glow during operation and
the acoustic signal functions, the rpm of the corre-
sponding shaft is no longer correct (i.e. slowdown of
speed due to belt slippage, broken belt, etc.). In this
case, stop the machine immediately and investigate
the cause of the problem.
