5.4 On-board System Troubleshooting
There are a number of tools available with the FS Trawl Monitoring
system that allows its performance to be checked. When these tools
are utilized as part of the regular maintenance they provide
information about the state of the system and allow it to be
monitored. This can be valuable in detecting problems before they
cause an FS system failure.
In the event the FS Trawl Monitoring system does not operate,
correct care must be taken to properly diagnose the cause of the
failure. Quite often the failure is thought to be with the FS
electronics when the actual cause is due to the winch slip-rings, the
interconnect cable or the trawl cable. The following sections
provide helpful advice on troubleshooting the FS system.
