3. OPERATING INSTRUCTIONS
Upon receiving your FAST
tracka
Instrument, follow these instructions to assure proper operation.
Failure to follow these instructions may result in damage to the instrument and/or injury to the
user.
3.1 UNPACKING AND ASSEMBLY
3.1.1 General Information:
Please note that the instruments are somewhat heavy, especially the battery pack. Be careful
not to drop or jar the instrument by improper handling.
The FAST
tracka
is shipped in a high-impact case designed to protect the instrument from shock
and vibration damage which often comes from handling during shipment. The instrument is
shipped with the battery pack separate from the instrument can, with a protective guard
surrounding the bulkhead connectors on the bottom. The battery pack may be attached prior to
instrument operation, or the instrument may be operated directly through the Deck Unit.
3.1.2 Battery Operation:
The battery to FAST
tracka
cable may be attached either before or after mechanically connecting
the two pressure cans. Attach the battery pack power lead to the correct bulkhead connector on
the bottom of the instrument can, see diagram. Do not place undue strain on this cable, either
as axial or bending loads. Undue strain will lead to premature failure of the connector.
Premature failure may result in accidental shorting of the battery packs inside the can, or flooding
of the battery pack. The pins and sockets of these connectors may be coated with Vaseline or
other appropriate lubricant in order to ease mating.
WARNING: Be especially careful when removing the cable from the battery pack. Removal of the
cable from the battery pack end will expose the male leads of the bulkhead connector, which are at
battery voltage and current. Physical injury may occur if these exposed pins are accidentally
shorted. The cable may be removed for cleaning and greasing, but never leave the battery pack
connector pins exposed where they might be accidentally shorted. Use a dummy connector or
preferably keep the cable in place.
To mechanically attach the FAST
tracka
can to the battery pack, first lubricate the mating surfaces
with Dow 4, Parker O-ring Lube, or another appropriate lubricant. Similarly coat the mounting
screws with a layer of lubricant. The mounting screws are either stainless steel or titanium and
will not appreciably corrode, but lubrication increases the ease of removal after lengthy
deployments. Mount the battery pack to the instrument can so that the battery cable is routed
out of the way of the other bulkhead connectors. Affix the greased mounting screws firmly so
there is no rocking or play between the cans. Rocking or play will chafe the mating surfaces and
may accelerate corrosion.
3.1.3 Deck Unit Operation:
