60 GC250 Technical Manual
EAAM057608EN
Some anomalies require the display of some additional information. For example:
The anomalies 198 and 199 (cumulative of pre-alarms/alarms received via CAN-BUS
from the electronic control units of the engines) also require the display of of the single
diagnostic codes.
For every diagnostic code it is shown:
o
The SPN code (it is a standard code defined by the SAE J1939 standard,
which identifies the mechanical component that is having the problem).
o
The FMI code (it is a standard code defined by the SAE J1939 standard,
which identifies the type of problem).
o
How many times this diagnostic code has been activated (OC).
o
The alarm code specific for the type of engine connected (DTC).
o
An alpha-numeric description (always in English) of the problem.
For MTU engines the SPN, FMI and OC are not shown, but the DTC code and
an alphanumeric description are always displayed.
If one or more of the above-mentioned information is not available, it will be
replaced by dashes or it will simply not be displayed. If multiple diagnostic codes
on the engine are active at the same time, they will be cyclically alternated on the
display every 2 seconds. The engine diagnostic codes are stored (even if the
engine deactivates them) until the yellow/red Can-Bus indicator light warning is
acknowledged.
Anomalies 252, 253, 254, 255 (referred to expansion modules) require the view of
the module/channel with the problem.
The additional information regarding the anomalies are shown on the last two lines of the
display. If two or more anomalies are shown, to display the additional information is necessary
to:
Press the button ▼.
Select the anomaly.

S.03 COMMUNICATION
Page S.03 views the communication status through the USB port and that of the CAN-BUS
interface of the controller. In case of functional problems, please, verify the content of this
page.
•
USB
: The status of the communication via USB is displayed through the symbols:
Ongoing communication.
Stand-by (no ongoing communication).
•
CANBUS
:There are three possible signalling:
- ERROR-ACTIVE: normal operation
- ERROR-PASSIVE: communication is working despite faults (errors).
- BUS-OFF: Gen-set has interrupted the connection to the bus due to too many errors.
The counters of the instantaneous transmission/reception errors and the maximum values
reached are displayed. To reset the maximum values (and at the same time force the exit
from the BUS-OFF status) it is necessary to:
Keep button ▼ pressed: the counters will be highlighted.
Press and hold the ▲ e ▼ buttons for five seconds.
