EXTERNAL BATTERY PACK
The OCEAN SEVEN 310 can be optionally equipped with an external 3.6 VDC submersible battery
pack. Aim of the external submersible battery pack is to enhance the internal battery capacity thus
extending the deployment period. Both, battery pack can be installed at the same time. The probe
electronic selects by itself from which battery the energy will be taken.
The external submersible battery pack comes complete with an international battery charger.
Recharging of the external battery pack foresees the opening of the battery housing and connection
of the battery charger with the battery pack. Detailed instruction about the external submersible
battery pack and battery re-charging can be found in the battery pack documentation.
The OS310 probe, if this option is present, is provided with a special Y-style submersible cable that
allows the simultaneous connection of the external battery pack and of the RS232C laboratory cable
to the “RS232&Power” top-cover bulk-head connector.
The Y-Style cable is mandatory to configure the CTD before deployment and to deploy the CTD.
Deployment of CTD with external battery pack
After the CTD has been configured, switch it OFF using the TOP COVER switch. Afterward remove
the RS232 laboratory cable from the Y-Style cable and plug-in the dummy connector to protect the
male connector. Now the probe is ready for the deployment.
NEVER disconnect the external battery after the probe has been configured, otherwise the
unattended setup will be lost.
