Testing Rpm - Valtra 6000 Workshop Manual

I. Testing RPM ---sensors (F1---F7) in the test mode in AC 5
NOTE! Corresponding tests in AC 5.2, see page 371/9A.
Note! If the display shows e.g. F1 51, it means the engine rpm sensor frequency of 5100 Hz (value x100=Hertz number).

DESCRIPTION
Set the engine revs to 1000 r/min and compare the value
with the given values in the LH side column. Raise the
revs to 1500 and 2000 r/min and compare the reading. If
one of the values is not within the given limits, check the
sensor, see instr. D on page 370/22.
Set the engine revs to 1000 r/min, engage gear M1 and
drive the tractor forwards. Compare the reading with the
given value. Test also at 1500 and 2000 rpm engine revs.
If the values differ, see instr. D sivulla 370/22.
Set the gears in neutral. Set the engine revs to 1000
r/min. Engage forward direction (F) and compare the
value with the given value. Make the same check also in
the reverse direction (R). Raise the engine revs to 1500 ( )
and 2000 r/min and measure again in both directions.
Compare the reading with the given values. If one of the
values deviates, carry out a comparing measurement,
check the sensor according to instr. D on page 370/22.
Engage PTO. Set the engine revs to 1000 r/min. Compare
the values with the given values. If the values deviate,
check the sensor acording to instr. D on page 370/22.
Set the gears in neutral. Set the engine revs to 800 r/min.
Engage the forward direction (F) and raise slowly the
engine revs up to max. The reading must be 1 and must
remain the same during the whole test. Engage reverse
direction (R) and repeat the same measurement. The rea-
ding must be 2 during the whole measurement. If one of
the direction readings does not function (value is faulty or
it changes when engine revs varie), but F4 and F5 values
are correct, the AC 5/5.2 control unit A1 may be damaged
and should be changed.
