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
troubleshooting 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 be-
gins 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 de-
tected 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 deacti-
vated. 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 fail-
ure and the engine start, the system recovers.
If medium failures are detected, the control is stopped and the system gets blocked.
The system is controlled only with the remote buttons and is not controlled from the main
console. The troubleshooting annunciator shows a failure code. After elimination of the
failure and the engine start, the system recovers.
