Guide).
• follow instructions in section 5. Software Reference .
3.10 POWER REQUIREMENTS
The FAST
tracka
is designed to draw its power from its own battery pack, thus removing the need
for an external power source. A fully charged 15 Ah battery pack will last for 24 h of continuous
flashing at 1 Hz flash rate.
The FAST
tracka
may be powered from the surface during host mode independent of the battery
pack. In this arrangement, power is supplied on an umbilical cable along with communication
and control signals. Operation in this fashion allows the instrument to be used from small craft
independent of winch operation for as long as there is power supplied at the umbilical end. The
FAST
tracka
requires 10.5 to 18 VDC supplied at the battery connector or 18 to 72 VDC at the
Interface connector, rated at 1.0 amp maximum. The Host power supply at the surface must be
set to always provide these parameters at the instrument.
The FAST
tracka
Deck Unit has two internal switchmode PSUs to
a) charge the battery pack and
b) power the instrument in Host Mode.
The Deck Unit may be supplied either with a UK standard mains plug or with bare wires for other
nationality plugs. The input for the Deck Unit is 100-240VAC, 50-60Hz, 3A. If supplied with bare
wires, the user must ensure that the appropriate mains plug is wired correctly. The three wires
within the mains lead will be colored:
1. BROWN: Live
2. BLUE: Neutral
3. GREEN: Ground
3.11 CHARGING REQUIREMENTS
The standard battery pack houses three tiers of 7 Gates X cells, each cell of 5.0 Ah at 2 volts.
The battery pack includes an intelligent battery charging circuit to monitor battery temperature
and charge state.
Charging the battery pack may be done at any time while not deployed. Firstly, make sure the
battery can is in a well ventilated area away from sources of spark and flame. Although the
Gates cells are of damp electrolyte construction and are virtually immune to outgassing
problems, it is always a good idea to ensure proper ventilation. The charge plug on the bottom
of the battery can will provide proper venting when removed, using the CI supplied battery
