3. MAINTENANCE PROCEDURES
3.1.
Mechanical inspection
Casing
Ensure there are no visible cracks or mechanical damage.
A cracked casing will lead to water ingress and is a serious fault.
Pole
Confirm the pole is intact and in good condition. The pole
should be checked by removing the cap from the bottom of the pole tube
and checking that the sections can be extended smoothly, and that they
lock into position. Ensure that the pole is fully stowed after inspection, and
that the end cap is secure.
Lanyard
The lanyard must be fully wound on the spool, such that only the ball
at the end is outside the casing.
Frangible tab
A broken frangible tab means that the SART may have been activated.
If this is the case, fit a new battery.
Battery expiry
Note the expiry date. If there is less than 6 months left contact
vessel and advise that they will need a new battery.
3.2.
Self test procedure
CAUTION:
Only test for the minimum time possible.
A live distress call may be received by other vessels within range.
Equipment
Testing requires a signal to trigger the SART out of sleep and into active/standby mode.
This can be supplied by :-
•
An X-band marine radar operating nearby (within 3 miles)
•
A dedicated SART tester (ARG 5420)
•
A 9.35 GHz microwave pulse generator, set for 1 us pulse every 1 ms.
In addition, to prove that the SART returns to sleep mode, the signal must either be turned off
(SART tester or pulse generator) or the SART upper section (radome) can be covered with a
metal container – a can of suitable size works well.
Test procedure
1.
Turn trigger signal off or cover radome with can
2.
