Operation

Check

Release the ballast using the Recovery tab in the OBS Command & Control widget. 900 seconds, as burning time, should be sufficient.

Check the Status in the OBS Command & Control widget / Post-Deploy tab to monitor the power going into the Burn-Wire release system.

Status can also be used to check the Aquarius depth while ascending to the surface.

When on the surface, LED will start working if it’s dark. The satellite tracker will send messages with its position to the first responders set in the web portal.

Bring the Aquarius on board.

Connect the Seacon Hummer series connector on the Aquarius and the Ethernet and console connectors to the Deck Unit.

In the Deck Unit, turn the PoE on.

    Open the OBS Command & Control widget, Pre-deploy tab, to check the clock offset and take note of it.

    Note: The offset will be correct only when the PTP stability is close to 100%. The offset is not stored in the SD cards.

    Download data from the Aquarius through the Storage tab in the LPC web server (see Section 7.2.5).

Before storing back the Aquarius for long time, charge batteries at least at 50% and plug the magnetic switch.
