5.1
Maintenance General Comments
Equipment used at sea is subjected to severe environmental and handling
conditions. While the Series 5000 Sonar System is designed to operate in such
conditions, a certain amount of routine maintenance is necessary to ensure trouble
free, long term operation.
Keep a maintenance log. This provides assistance in tracking what has or has not
been done with the system. A log is useful when tracking problems, if they do
occur, and is especially important if more than one TPU, Computer Control and
Display Unit (computer), or towfish is used in a large survey operation. Inventory
the system, related spares and accessories carefully. Record the serial numbers of
the major components, such as the TPU, the computer, and the towfish. Store the
shipping boxes in a safe place so they can be reused when needed. A small amount
of regular maintenance and care makes the critical difference in a successful field
operation. The following pages contain the recommended routine checking and
maintenance schedules for a daily, weekly, and long term basis.

Maintenance Checklists
5.2.1 Daily Maintenance Checklist
Perform the following maintenance steps at the end of each day’s operation:
1.
Turn off the power to the TPU and to the computer.
2.
Verify that all cables and connectors are secure and tightened.
3.
If fresh water is available, wash down the towfish and towing apparatus. Cover
them while not in use to protect against salt water spray and to minimize
corrosion.
