ERROR HANDLING
An error is detected as such by the processor only if it is applied for a minimum period (mostly 200 ms). In
this way, brief and non-critical error events due to signal noise or delays in the sensing elements are not taken
into consideration.
If an error is detected by the processor, the following occurs:
- The fault warning lamp flashes.
- Interventions are controlled by the microprocessor depending on the seriousness of the errors: truck
deceleration, RPM limitation, solenoids de-energised, etc.
- An error number describing the fault is stored in a non-volatile store (EEPROM).
- The error number can be read in the windows <2> and <3> of the diagnostic unit.
A troubleshooting with the diagnostic unit is possible at any time subsequently. The error number, stored
in the EEPROM when the fault occurred, can be displayed by selecting window <3> of the diagnostic unit.
In this way it is afterwards possible to identify unstable, sporadic or non-reproducible errors.
TEST CONDITION
The battery voltage should be at least 11.3 V.
Before starting work on the LHC diagnostic program, identify the software version (shown in window 1).
Depending on the software version, select the diagnostics description as follows:
from 1.1 to 1.3 Section 2.10.1.3.2
from 1.4 and 1.5 Section 2.10.1.3.4
ab 1.6 Section 2.10.1.3.6
NOTE: The first step in the diagnosis should be to perform a calibration of the traction potentiometer
in window 8 of the respective software version.
All of the values given in the windows in the document are examples only.
