Appendix A. Troubleshooting
Situation
Possible cause and correction
The LED does not signal
after the NMEA 2000
network is powered on
1. No power supply on the bus.
Check if the bus power is supplied
(NMEA 2000 network requires a separate power connection and cannot
be powered by a plotter or another device connected to the network).
2. Loose connection in the power supply circuit.
Treat the Device
connector with a spray for cleaning electrical contacts. Plug the Device
into another connector.
The Device LED flashes
every five seconds, but the
Device is not displayed in
the list of external devices
on the plotter, data do not
appear, the state of NMEA
2000 network always is
«red»
1. Loose connection in the data circuit.
Treat the Device connector
with a spray for cleaning electrical contacts. Plug the Device into another
connector.
2. There are problems in the NMEA 2000 network.
The network
segment is not connected to the plotter or there are missing terminators
in the network. Plug another device into the selected connector
and make sure it appears in the list of devices on the plotter. Note: please
see VIII and VII.1 also.
Ignition on, but the engine
network status displays
a red flashing light, data
about the activity of the
engine is not coming to the
chart plotter
1. Improper connector selected.
Make sure that the engine connector
of the Device is connected to a right connector. To check the connector with
a multimeter see V.
2. No connection between CAN1 and CAN2.
If you connected
the Device to a free connector or, instead of a existing device in a Volvo
Penta EVC network, install the plug supplied with Device into a free
Device’s connector.
3. Invalid interface speed selected.
Volvo Penta EVC and J1939
networks use a speed of 250 kbps (used by default), BRP CAN networks
use 500 kbps. See V.20.
