Kongsberg AIS 200 Installation Manual, rev. 2 Maintenance
6. MAINTENANCE
6.1 General
All units in the AIS 200 system are “repair by replacement” units, and the operator is
therefore required to perform only a limited amount of preventive maintenance on the units.
The service in the field is limited to:
•
Replacing damaged GPS or VHF antenna cables
•
Replacing failed AIS 200 system units
A damaged unit that has to be shipped back to the supplier, should be sent in the original
transportation box or another appropriate box. The return address is provided in the first
pages of this manual.
6.2 Periodic maintenance
The AIS 200 system should regularly be checked for firm and fixed mounting of the chassis
in order to avoid excessive resonances. All connectors should be checked for good
mechanical and electrical connections. Cables should not be bent more than the minimum
recommended bending radius and there should be no sharp bends on coaxial cables. All
cables should be fixed tight and rigid to their supporting structure (bulkhead, mast etc.) and
special care should be taken where cables run through holes with sharp edges.
6.2.1 MKD Units
The MKD will under normal use require little maintenance.
If the unit requires any form of cleaning, use fresh water and a mild soap solution (not a
detergent). It is important to avoid using chemical cleaners and hydrocarbons such as diesel,
petrol etc.
6.2.2 Mobile Unit
A properly operating Mobile Unit will indicate transmitting and receiving messages by short
blinks on the
TX and MSG LEDs. Inspecting the LEDs for normal operation gives a good
indication of the operating status. Any red LED indication means that further investigation
and servicing is necessary, see chapter 7.1.
