8 MAINTENANCE
8.1 General
The Seatex AIS 100 consists of both software and hardware. The
software part can be reinstalled or upgraded to the latest version in the
field by running a software installation procedure. Service of the
Seatex AIS 100 hardware in the field can consist of:
•
Exchange of damaged GPS or VHF antenna cables.
•
Exchange of failed GPS or VHF antennas.
•
Exchange of failed Seatex AIS 100 mobile station .
The Seatex AIS 100 requires a skilled technician to maintain most of
the hardware service.
8.2 Periodic maintenance
The AIS 100 should regularly be checked for firm and fixed mounting
of the chassis in order to avoid vibration and shock. 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.
A properly operating unit will show when it is 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. In particular, there should be no red LEDs,
because red indicates alarms or severe faults. Any red LED indication
means that further investigation and servicing is necessary.
8.3 Repairs and modifications
Repair of the Seatex AIS 100 consists of exchange of damaged
antenna cables, exchange of GPS or VHF antenna and replacement of
the Seatex AIS 100 mobile station, connection box or MKD. Any
skilled electrician should be able to do this.
