Assignment And Operation Principle Of Integrated Indicator Gauges - Belarus 2022.6 Operator's Manual

Control panel 16 (figure 2.1.1) allows to carry out manual programming of the indi-
cator with buttons "Parameter" and "Value" (see figure 2.8.2), and also to change the
mode of showing data entered on the multifunction display with "Mode" button. The "Mode"
button is also used to enter a non-fixed parameter value when programming the device.
The rules on IICP use in the mode of displaying operational parameters and failure
messages on the multifunction display are given below in subsection 2.8.2 "Assignment
and operation principle of II gauges".
The rules on IICP use in the II programming mode are given below in subsection
2.8.5 "The order of Integrated Indicator programming".
To get access to buttons "Parameter" and "Value" it is necessary to remove cover of
II control panel.

2.8.2 Assignment and operation principle of integrated indicator gauges

2.8.2.1 Velocity gauge 1 (figure 2.8.1) indicates tractor design speed on a needle
indicator. Design speed exceeds the actual one as tractor skidding is not taken into ac-
count.
Velocity gauge 1 is actuated by signals coming from pulse sensors of rotation fre-
quency of toothed gears of final drives of right and left rear wheels. The speed is indicated
in accordance with the signal from the sensor installed on the final drive gear of the wheel
rotating 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 liquid
crystal display as "0" digit, characterizing the fault location – to the right or to the left (see
below).
2.8.2.2 Engine speed gauge 2 (figure 2.8.1) indicates rotation frequency of the en-
gine crankshaft on a needle indicator.
Information on engine speed comes from the electronic control unit. The range of speed
indications is from 0 to 3500 (rpm).
2.8.2.3 RPTO speed gauge 3 (figure 2.8.1) displays the RPTO speed on a light in-
dicator.
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
erates in the following way:
- the annunciator of "540 min
- as the speed of the rear PTO shaft end extension reaches 320 min
segment of the rear PTO gauge 9 lights up in combination with the annunciator 6.
- as the speed further increases, together with annunciator 6 the rear PTO indicator
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
indicator 3 in accordance with the upper lighting segment of the RPTO according to table
2.8.1.
When switching the mode "540 rpm economic" the operating order of the rear PTO
speed indicator 6 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
2.8.1);
- 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.
