NOTE: For further details of DSEE050 Configuration, refer to DSE Publication 057-299
DSEE050 Configuration Suite PC Software Manual.
Issue Check
Display and buttons are not
illuminated. If Power Saving is enabled within the device configuration,
the backlight and button lights are extinguished after a
(configurable) delay. Illumination resumes upon CAN data
being received or upon the press of any button.
Display Backlight and/or buttons
dim during engine start procedure. This is to reduce power usage. The LCD backlight and
button backlights are switched off when the DC supply falls.
This occurs most commonly during engine cranking.
However, this can also be a symptom of an electrical fault
such as a depleted battery or failing battery charge system.
Button backlights do not illuminate;
however, the display remains
illuminated. Should the device internal temperature be too high, the
button lights are extinguished to lower the temperature and
protect the internal systems. Ensure adequate ventilation to
ensure the temperature of the device does not exceed
specifications.
Inputs and outputs cease to
function during engine start
procedure. This is to reduce power usage. Device inputs and outputs
are disabled when the DC supply falls. This occurs most
commonly during engine cranking. However, this can also be
a symptom of an electrical fault such as a depleted battery or
failing battery charge system.
CAN messages not received.
•
Check the CAN connections are correct including cable
type and termination resistors as specified in the section
entitled
Connection Description elsewhere in this
document.
•
Factory Settings (defaults) of DSEE050 expects the
ECU to send CAN data from Source Address 0. Where
the ECU is not Source Address 0, the
CAN ID of the
messages to receive must be amended in the
configuration of DSEE050.
•
Factory Settings (defaults) of DSEE050 expects the
ECU to send CAN data with the priority as specified by
SAE J1939 for
Default Priority . Where the ECU sends
messages of differing priority, the CAN ID of the
messages to receive must be amended in the
configuration of DSEE050.
++++, ----, XXXX, #### shown on
the display. These are displays to show an abnormal instrument value or
an instrument in a fault condition. For further details see the
section entitled
Engine and Analogue Input Instrumentation |
Sentinel Values elsewhere in this document.
If most instruments are displaying #### along with the
icon, this indicates CAN communications is not functioning.
See
CAN Messages not Received elsewhere in this section.
#### is shown for some
instruments while others display
correctly.
