2.17.4 Troubleshooting of RLL electronic control system

The electronic control system installed on your tractor has an option of self-testing and if
any failures are detected, it provides the operator with code information by means of trou-
bleshooting annunciator 5 (figure 2.17.1) on RLL control panel. After the engine start, as
specified in subsection 2.17.2, annunciator 5 is constantly on, if no failures are detected in
the RLL control system. Moving handle 11 up or down deactivates annunciator 5.
If any failures are detected in the system after the engine start, annunciator 5 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 annunciator 5 after the first long pause, and the second digit is
equal to the number of flashings after the second long pause. For example, the operation
algorithm of annunciator 5 is the following:
- engine start;
- continuous glowing;
- after unblocking the system, the annunciator goes out;
- three-time flashing of the annunciator;
- long pause (glow missing);
- six-time flashing of the annunciator;
- long pause (glow missing).
It means that the system has a failure with a code "36". If several failures are detected at
the same time, the system indicates failure codes one after another dividing them with a
long pause.
All failures are divided by the system into three groups: complex, medium and light.
If complex failures are detected, the control is stopped and the system gets deactivated.
The system is not controlled with the control panel or with the remote buttons.
The troubleshooting annunciator shows a failure code. After elimination of the failure and
the engine start, the system recovers.
