6.
If the pinger is fitted with an external connector then the connector MUST be terminated
or blanked.
4.3.
DEPLOYMENT
1.
At least 24 hours prior to deployment, any personnel who are to be involved in the
operation of the pinger should review this entire manual and be given time to practice
operating the pinger and receiver system. By familiarising themselves with the system
operation prior to deployment, the chances of a potentially costly operator error are
greatly reduced.
2.
Refer to Page 2 of this manual for the expected battery lifetime and ensure it is adequate
for the planned duration of operations.
3.
Fresh batteries are installed at OEL prior to shipping, however if the unit has been
deployed previously, the batteries should be replaced as detailed in Section 4.4 prior to
deployment.
4.
Ensure that the battery endcap is tightened.
5.
If the pinger is fitted with an external connector then it must be terminated or blanked.
6.
It is recommended that the pinger is activated by bridging the saltwater links with the
mechanical link provided, however the pinger will also activate if the saltwater contacts
are flooded with a conducting fluid such as salt water, fresh water or MEG. If using the
mechanical link to bridge the contacts, the heat shrink will need to be removed
beforehand.
7.
Perform a FUNCTION TEST as described in Section 4. Providing the function test has been
completed successfully, deployment can proceed.
4.4.
BATTERY REPLACEMENT
1.
Familiarise yourself with the NOTES given at the start of Section 3 RULES FOR SAFE
OPERATION.
2.
Remove the BATTERY ENDCAP slowly to relieve any internal pressure.
3.
Remove all C Cells. Visually inspect the batteries, contact Online Electronics immediately if
there are any signs of damage or electrolyte leakage. Dispose of the old batteries in a
responsible way.
4.
Observing the battery polarity shown in the figure below, insert the new C Cells into the
battery compartment, POSITIVE END first. Note that the unit is programmed with a set
battery configuration so that it will stop pinging when the supply voltage drops below a
threshold level. Since the threshold level is dependent on the cell configuration, the
replacement cells must be of the same type as the original cells.
5.
Once all batteries are installed, ensure that it is the FLAT, NEGATIVE END of the batteries
which you see when looking into the open end of the unit.
6.
Examine the O-ring seals for any signs of contamination or damage, replace and/or re-
grease if necessary.
7.
Ensure all the O-rings are located correctly and then refit the BATTERY ENDCAP.
