2.15.3 Remote buttons of RLL control system

Remote buttons of RLL control are used as a rule for coupling agricultural imple-
ments and machines to the rear lift linkage.
Uplift and lowering of the rear lift linkage with the remote buttons on rear wheel
fenders can be carried out at different control modes – the handles 1, 2, 3, 4, 7 (figure
2.15.1) and similar handles of the RLL control console
the system of control from inside the cab is hereby blocked.
To lift the RLL up, press any of the buttons 4 (figure 2.15.3) and hold it depressed.
To lower the RLL, press any of the buttons 5 and hold it depressed.
For safety's sake the control with the remote buttons is performed with interruption
of work. Pressing the uplift button 4 (lowering button 5) and holding it depressed lifts up
(lowers) the RLL for 5 sec., then it stops. For further uplifting (lowering) it is necessary to
press the corresponding button once again and hold it depressed!
Then after the implement has been attached, activation and work with HLL is per-
formed in accordance with subsection 2.15.2.

2.15.4 Troubleshooting of RLL electronic control system

The electronic control system, installed on your tractor, has an option of self-testing
and whenever failures are detected it provides the operator with code information by
means of a troubleshooting annunciator 9 (figure 2.15.1) on RLL control console. After en-
gine start, as specified in subsection 2.15.2, the annunciator 9 is burning continuously if no
failures are detected in RLL control system. Moving the handle 7 up or down deactivates
the annunciator 9.
In case failures are detected in the system after the engine start, the annunciator 9
begins to show code information of the failure. If necessary the system gets blocked.
The failure code is displayed as a two-digit number, where the first digit is equal to
the number of flashings of the annunciator 9 after the first long pause, and the second digit
is equal to the number of flashings after the second long pause. For example, the opera-
tion algorithm of the annunciator 9 is the following:
