42 records. Every following record overwrites the older one. The controller records the
analogue values described in par. 0.
7.4.9.6
Locked recordings
Analogue and events recordings are temporarily OFF
when in “OFF/RESET” mode.
When the records are blocked, on the second line a lock is displayed before the partial
number of events or records in all windows of the history log. In this situation, the counters
inside the controller keeps on decreasing the time for the time limit of the next recording.
When the operation mode shifts from “
OFF/RESET
” to “
MAN
” or “
AUTO
”mode, a check is
performed in order to verify whether some recording counter expired. If so, the recorded date
and time of the status change are stored, otherwise the count continues till the next recording
is stored.
7.4.9.7
Engine diagnostics pages (DTC)
The controller records only the DTCs the engine control unit (ECU interface) sends over the
CAN-BUS line.
Basically, depending on the installed engine, the diagnostic message consists of the DTC,
SPN and fault description. This archive have can store up to 16 records. Every following
record overwrites the older one.
To display all records, the controller uses one page of the display.
The second line shows the record currently displayed, out of the total number of records (the
maximum number of records is 16).
The fourth line shows the recording date and time.
The sixth line shows the diagnostic code. It contains:
Engines implementing the SAE J1939 standard (all those selectable with the parameter
P.0700 , excluding the MTU). Diagnostic information according to the standard J1939 are
provided for this type of engines:
SPN (Suspect Parameter Number): is a numeric code showing the engine
part/component that generated the diagnostic code (in the example, “100” identifies oil
pressure measure).
FMI (Fault Mode Identifier): is a numeric code between 0 and 31 that identifies the kind
of problem (in the
example, “1” indicates an excessively low value of the measure, thus
requiring engine stop).
OC (Occurrence Count): indicates how many times this diagnostic code has already been
activated (example “2”).
Further to this, if the controller knows the combination of codes SPN ans FMI , a
description of the problem is displayed. Finally, if the controller knows the said combination
due to the engine selected, also the diagnostic code associated to the problem is shown,
findable on the engine technical manual (in the example
, code “6.6” in the engine technical
manual will describe the oil low pressure problem).
