Operation
Gauge driver outputs
The gauge outputs operate when CANdrive reads valid J1939
data for engine speed, oil pressure and coolant temperature.
If CANdrive stops receiving valid data, the gauge outputs
are maintained at the last known value for approximately
5 seconds, after which time the outputs turn off.
Indicating LEDs
All standard models have a green CAN LED. A flashing
CAN LED indicates that CANdrive is powered, but is not
receiving any J1939 data. A constantly lit CAN LED indicates
power on with good CANbus connection and J1939 activity.
(Note: J1939 activity can originate from ANY device on the
CANbus network, and may not necessarily be valid data from
the engine ECU.)
Model CDV300R has additional LEDs for indication of J1939-
transmitted engine faults. CANdrive responds to single
DM1 (active fault code) messages that contain SPN (Suspect
Parameter Number), FMI (Fault Mode Indicator) and
warning/stop lamp data. CANdrive also reads multi-packet
transport messages broadcast using the BAM protocol.
Typically, LEDs light continuously to indicate a shutdown fault,
and flash to indicate a (non-shutdown) warning fault:

CANdrive can handle up to 8 simultaneous faults at
one time: additional fault messages are not registered.
When a fault becomes inactive and is no longer broadcast,
the appropriate LED goes out after approximately 2 seconds.
Maintenance and Warranty
CANdrive has no user-serviceable parts. Maintenance is
therefore limited to the following preventative checks:
x
Check that electrical connections are secure.
x
Check that the CANdrive is securely mounted, and
kept free from ingress of water or build up of excessive
dust/dirt. The front label and casing may be wiped with
a clean, damp cloth. Do not use cleaning solvents.
CANdrive is supplied with a 2 year warranty on parts and
workmanship. In the event of a fault or technical query, please
contact your Murphy representative for technical support.
