Programming mode and
“Accurate time” mode are possible
after full stop of the vehicle.
Transition to programming mode
provides for the possibility of review and
change of parametric values according to table
2.
.
Name of parameter being
programmed
Designation of group and number of
parameter in group (most significant
digit of the indicator)
Range of numeric
values being
entered
Transfer ratio of wheel
reduction gear
К1
from 1.00 to 5.00
Transfer ratio of generator
drive
К2
from 1.00 to 5.00
Transfer ratio of PTO540
КЗ
from 0 to 1.00
Transfer ratio of PTO 1000
K4
from 0 to 1.00
Radius of rear wheel rolling
R
from 400 to 999
Number of gear teeth where
speed sensor is mounted
Z1
from 10to
о 99
Number of gear teeth where
sensor of PTO revolutions is
mounted
Z2
from 0 to 99
Note – When sensor of PTO revolutions is not available, value Z2 being entered equals
“0”, and signal from phase generator winding serves as signal for indicator of PTO
rotation speed.
Algorithm of I K programming
Transition to programming mode is
made by pressing push button
“Parameter” and keeping it pressed for
at least 2 seconds. During transition to
programming mode the user
automatically obtains the mode
“Accurate total time of engine
operation”. In this case light-emitting
diode close to symbol “T” is alight. From
accurate time mode the user may switch
over to the main mode (indication of
total engine operation time, or
movement speed) by pressing push
button “Value”;
- to the following parameter K1 and
further on along the cycle by pressing
push button “Parameter”.
Transition from one parameter to
another is made according to the
following cycle:

, - and so on
Data input (changing of the numerical
value of parameter) is made in the
following way:
- using push button “Parameter” select
the required parameter to be corrected;
- to change parameter value press
button “Value”, and then with period of
0.3 s the least significant digit of the
digital indicator (the first from the right
side);
