List of programmable coefficients of the KD8083 integrated indicator for the BELA-
RUS-892/892.2 tractors is given in Table 3.14.2.

Parameter value Paramete
r
T parameter
In the programming mode, when you first press button 1 and
hold it for more than two seconds, the digital indicator displays
the value "Refined elapsed engine operation time". This param-
eter is not available for change, it provides a refined value (up
to 1/100 hour
)
of the en
g
ine o
p
eration time
K1 parameter
The ratio of the wheel gear group.
(parameter for displaying tractor speed)
K2 parameter
The ratio of the alternator drive.
(parameter for displaying engine speed)
K3 paramete
r
The ratio of the PTO drive (540 rpm)
(parameter for displaying PTO speed in 540 rpm mode)
K4 paramete
r
The ratio of the PTO drive (1000 rpm)
(parameter for displaying PTO speed in 1000 rpm mode)
or
R paramete
r
R is the rolling radius of the rear wheel, mm. When repro-
gramming, it is possible to change this parameter with 5 mm
increment
1)
Z1 parameter
Number of gear teeth at the point of the speed sensor (pa-
rameter for displaying tractor speed)
Z2 paramete
r
Number of gear teeth at the point of the PTO speed sensor
Note - for the BELARUS-892/892.2 tractors, the value of the Z2
parameter is set to "0" due to the absence of the PTO speed sensor
(the signal from the phase winding of the alternator serves as a sig-
nal for indicatin

770 – value for tires 18.4R34(F-11), 800 – value for tires 16.9R38. When mounting
other types of tires, it is necessary to set the value of the parameter "R", corresponding to the roll-
in
g
radius of the tires in accordance with Table 3.9.1.
During the operation, it is allowed to modify values of the parameter of the wheel rolling radius
“R”, which is determined based on the tires mounted on the tractor, by measuring the distance from
the wheel center to the bearing surface.
IT IS FORBIDDEN TO MODIFY THE INPUT VALUES OF ALL OTHER PARAMETERS
(FACTORY DEFAULTS).
