Belarus 921.6 Operator's Manual page 38

The list of programmable parameter values for the BELARUS-921.6 tractor (graphical
examples of the parameters displaying and their values on the multifunction indicator in the
programming mode) is shown in Table 2.8.4.
Table 2.8.4
________________________________________________________________________________________
1)
585 – value for 420/70R24 tyres. When the 14.9R30 tyres are installed, it is nec-
essary to input value 660. When other tyre types are installed, it is necessary to set the
parameter R value, which corresponds to the installed tyres' rolling radius.
2)
The BELARUS-921.6 tractor is not equipped with the PTO shaft RPM sensor;
therefore, it is necessary to input value 0 here.
During operation, it is allowed to change the values of the "tyre R rolling radius" pa-
rameter, which is determined based on tyres installed on the tractor by measuring the dis-
tance from the wheel centre to the supporting surface.
IT IS PROHIBITED TO CHANGE ANY SET VALUES OF ALL OTHER PARAME-
TERS (FACTORY SETTINGS)!
Parameter Z
Z – quantity of the final shafts gears teeth in the rear wheels
(right and left) above which the speed sensors are installed
Parameter I
I – multiplying ration of the wheel reduction gear transmission
ratio
Parameter R
R – rear wheel rolling radius, mm. This value can be changed
during programming with minimum resolution 5 mm
Parameter KV2
KV2 – transmission ratio of the rear power take-off shaft
Parameter ZV
ZV – quantity of teeth of the rear PTO shaft toothed washer
Parameter V
V – fuel tank volume, l
In addition, when the Parameter button is pressed in program-
ming mode, the list of programmable parameters will display the
independent parameter T of the clarified value of the engine total
operating time counter. This value cannot be changed and repre-
sents exact value (up to 1/100 hour) of the engine operation time.
