Sequence # | Pre / Post | Description |
LAB PREPARATION | ||
Charge the battery pack | ||
Assemble, as needed, and inspect power and signal connections in computer tray | ||
Mount communications tray into upper end cap | ||
Insert optical fibre into upper end cap | ||
Inspect o-rings and tighten bolts on optical fibre connector (or blank) | ||
Connect fibre (5 x fibre-ST) to communications components | ||
Mate and inspect video (2 x composite) connection to fibre transceivers | ||
Slide computer tray (halfway) into upper enclosure | ||
Connect video (2 x S-video) between computing tray framegrabber and cameras (via upper end cap) | ||
Connect video (1 x composite) between computing tray camera and fibre transceiver | ||
Connect Ethernet (1 x RJ-45) between computing tray and fibre ethernet components | ||
Slide computing tray forward to marks | ||
Ensure that computer tray grounding tab contacts upper enclosure | ||
Connect 24 volt power connector to computing tray | ||
Connect motor amplifier control lines (5 x RJ-45) and PSU disable line | ||
Connect 4 fibre transceiver power cables and 2 camera power cables to power supply board | ||
Visually inspect acrylic dome O-rings for gaps | ||
Clean upper end cap O-rings of any dirt or particles, removing if necessary | ||
Grease O-ring taking care not to stretch it | ||
Grease upper enclosure mating surface | ||
Tuck cables into upper end cap (out of contact with power converters) | ||
Mate upper end cap, tighten nuts to 4.86Nm evenly and diagonally | ||
Visually inspect upper end cap O-ring for good seal | ||
Inflate trolley tyres if necessary | ||
Place sub, battery pack and fibre roll into trolley | ||
Take trolley to pool enclosure via lift | ||
POOL SIDE | ||
Test ethernet connection to Syseng | ||
Slide battery pack into lower enclosure (mind your back) | ||
Lock battery pack into place | ||
Ensure the battery pack is grounded to the lower enclosure | ||
Connect 12 volt relay power to battery | ||
Connect lower enclosure leak detection sensor | ||
Ensure relay is "disarmed", power to relay is off | ||
Connect 24 volt connector to battery and place connector on LHS of tube | ||
Switch on power to relay | ||
Check relay "armed" light blinking red | ||
Clean lower enclosure O-rings of any dirt or particles | ||
Grease O-ring taking care not to stretch it | ||
Grease lower enclosure mating surface | ||
Tuck cables into lower enclosure away from mating surface | ||
Mate lower end cap (there should be minimal resistance), tighten nuts to 4.86Nm diagonally and evenly | ||
Visually, and by touch, inspect lower end cap O-ring for good seal | ||
Inspect all glands (there are 30 total) | ||
Inspect all thrusters, checking housings and blade wing nuts | ||
Manually rotate thrusters to detect contact with cowling | ||
Apply magnet, check relay "on" light blinking green, power up system | ||
Note that pan tilt camera homes, light to power converters come on, indicators on computer come on | ||
Connect ethernet and video monitor to surface transceivers | ||
Setup and run support computers and equipment | ||
Check that ethernet and video signals are being transmitted | ||
Perform software load and run to test functionality | ||
Attach crane hook onto sub frame | ||
Lift pool cover, fold it and lay it on a clean surface | ||
Switch off the pool filter pump | ||
Attach tethers to the sub frame | ||
IN THE WATER | ||
Hoist Kambara into the water (mind the fibre, magnet cord and tethers) | ||
Watch for excess bubbles! | ||
Drop live fish into the water | ||
Watch Kambara herd them into the corner |
