Troubleshooting

Table 12 - Troubleshooting Symptoms and Check Procedure
• Ensure that the CLMD16 is properly connected to the
NMEA 2000 ® network.
• Ensure that the CLMD16 instance of the breaker/switch
component matches the instance programmed into the
CLMD16, as described in Advanced Tab on page 39
The CLMD16 may have shut down the affected channel due to an
over-temperature or over-current condition detected on the
CLMD16 breaker itself.
• Ensure that the current drawn by the load is less than the
current rating for the connected channel.
• Ensure that no short circuits or other wiring problems exist
on the load circuit, and reset the channel by turning it 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 CLMD16 channel that the breaker/switch
component is controlling.
• Ensure that the load's terminal which is not connected to
the CLMD16 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.
