The control panel 16 (figure 2.1.1) allows to carry out manual programming with but-
tons « » (“Parameter”) and « » (“Value”) (see figure 2.7.2), and also to
change the mode of showing data entered on the multifunctional display with « »
(“Mode”) button. The “ ” (“Mode”) button is also used to enter a non-fixed parameter
value when programming the device.
Rules on use of the IICP in the mode of displaying operational parameters and failure
messages on the multifunctional display are given below in subsection 2.7.2 “Assignment
and operation principle of II indicators”.
Rules on use of IICP in the II programming mode are given in subsection 3.21.3 “In-
tegrated Indicator programming order”.
2.7.2 Assignment and operation principle of integrated indicator gauges
2.7.2.1 Velocity gauge 1 (figure 2.7.1) indicates a design speed of the tractor on a
needle indicator. The design speed exceeds the actual one, as tractor skidding is not
taken into account.
The velocity gauge 1 is actuated by signals coming from pulse sensors of rotation
frequency of toothed gears of final drives of right and left rear wheels. The speed is indi-
cated in accordance with the signal from the sensor installed on the final drive gear of the
wheel, turning with a less speed.
In case one of the speed sensors is faulty the integrated indicator shows speed
readings in accordance with the signal coming from the correct sensor. Specific faults of
circuits or speed sensors when the signals from them are missing are displayed in the mul-
tifunctional indicator as “0” digit, characterizing the fault location – to the right or to the left
(see below).
2.7.2.2 The engine speed gauge 2 (figure 2.7.1) indicates rotation frequency of the
engine crankshaft on a needle indicator.
Information on engine speed comes from the alternator phase winding. The range
of speed readings is from 0 to 3500 (rpm).
2.7.2.3 Rear PTO speed gauge 3 (figure 2.7.1) displays the rear PTO speed on a
light indicator.
The rear PTO speed gauge is actuated by signals coming from a pulse speed sen-
sor, installed above the toothed washer of the rear PTO reduction unit.
Upon engaging the rear PTO in the mode of “540 min
-1
” the integrated indicator op-
erates in the following way:
- the annunciator of “540 min
-1
” of rear PTO speed scale range 6 lights up;
- as the speed of the rear PTO shaft end extension reaches 320 min
-1
a lower seg-
ment of the rear PTO gauge 9 lights up in combination with the annunciator 6.
- as the speed further increases, together with the annunciator 6 the rear PTO indi-
cator segments light up successively from bottom upward in the following order: 8 – 7 – 5
– 4;
- then in the process of the rear PTO operation the rear PTO speed is displayed on
the indicator 3 in accordance with the upper lighting segment of the RPTO as per table 2.2.
The working order of the rear PTO speed indicator 6 when switching the mode “540
rpm efficient” is the same as for the mode “540 rpm”.
Upon engaging the rear PTO in the mode of “1000 rpm” the integrated indicator op-
erates in the following way:
- the annunciator of “540 rpm” of rear PTO speed scale range 6 lights up (figure
2.7.1);
- as the speed of the rear PTO shaft end extension reaches 320 rpm a lower seg-
ment of the rear PTO gauge 9 lights up in combination with the annunciator 6.
