Troubleshooting Procedure
• Ensure that the DCR100 is properly connected to the NMEA
®
®
2000 network.
• Ensure that the DCR100 instance of the breaker/switch
component matches the instance programmed into the
DCR100, as described in Section 2.5.1.1.
• Ensure that the DCR100 has the appropriate NMEA 2000
PGNs enabled as described in Section 2.5.1.1.
The DCR100 may have shut down the affected channel due to an
overtemperature or overcurrent condition detected on the DCR100
relay itself.
• Ensure that the current drawn by the load is less than 10A.
• Ensure that no short circuits or other wiring problems exist
on the load circuit, and reset the channel by turning OFF,
then ON.
• If the breaker or switch control returns to the error state,
closely examine the load wiring for problems and ensure
that the load draws the appropriate amount of current.
• Ensure that the load is connected to the load terminal of the
same DCR100 channel that the breaker/switch component
is controlling.
• Ensure that the load's terminal not connected to the
DCR100 is connected to vessel ground.
• Ensure that the connection between the breaker and the
channel's power terminal is good.
• Ensure that the breaker supplying power to the channel is
not tripped.
• If you are controlling the load via a DSM250 display, ensure
that it is running at least firmware revision 1.4.10.
• If you are controlling the load via N2KView software, ensure
that you are running the Platinum version of the software.
The Basic version can display, but not control, DCR100
channels.
