Section 2 Operation and maintenance
2.1 Verify operation
WARNING
If the user thinks that the alkaline batteries have leaks, pressure may have built up
inside of the pressure housing. Follow ESD protocols to release internal pressure. Put
on safety glasses and protective gloves and make sure that the sensor is pointed away
from the body and other people. In a well ventilated very SLOWLY loosen the bulkhead
connector to release the pressure. Keep away from heat, sparks, flame, and other
sources of ignition. Do not smoke.
Attach all cables to the system to be deployed and make sure that the battery supplies
sufficient power.
• Voltage for the 15 V pack should be between 15 and 17.5 VDC.
• Voltage for the 13.5 V pack should be between 13.5 and 16 VDC.
2.2 Remove and replace end flange and batteries
WARNING
The unit may be pressurized. Point the unit away from the body and face and pull up on the
pressure relief valve to release any residual pressure from a deployment. Point the unit away from
the body and face to remove the end flange.
1. Make sure that the battery pack is not pressurized.
2. Disconnect any cables from the battery pack.
3. Remove and save the two 10-32 screws that attach the end flange to the pressure
housing.
4. Hold the pressure housing pointed away from the body and face and carefully pull the
handle on the end flange to remove it from the pressure housing. This will take some
effort because the end flange has two O-rings. Be careful not to pull the end flange
too far from the pressure housing as this could cause damage to the electrical
connector.
5. Disconnect the electrical connector and set the end flange aside.
5

6. Remove the retaining nut.
The printed circuit board (PCB) will rise because of the battery spring contacts.
7. Remove the PCB by the handle. Make sure not to pull on the electrical wiring. Make
sure the battery contacts on the PCB are clean.
8. Remove the batteries from the pressure housing.
9. Follow local regulations to recycle the batteries.
10. Make sure that the O-rings are pristine. Replace them if there is any question.
11. Insert new cells. Make sure that the positive tabs face up.
Operation and maintenance
6

12. 51 Ah units: install four D cell batteries with the positive tab face up, in each of the
other three columns marked in red.
13. 51 Ah units: install a dummy D cell in each marked column, then install four more
batteries on top of the dummy cells to fill the marked columns. Make sure the
batteries and the dummy cells have the tab of the positive ends face up.
14. Install the PCB again. Make sure to align the pin with the hole in the PCB assembly.
15. Install the retaining nut and tighten it until the PCB mounting plate bottoms out on the
center column of the internal battery holder.
16. Measure the voltage of each column and verify that it is within the specified range.
Use a voltmeter to touch the positive check points and the negative contact washer.
Operation and maintenance
7

17. 51 Ah units: measure the voltage for the three columns with real batteries.
18. Put the leads of an ohmmeter on either end of each fuse to make sure that they have
a value of near 0. There is a small internal resistance of approximately 0.5 ohms.
19. Connect the two-wire connector on the PCB assembly to the connector on the end
flange.
20. 51 Ah units: connect the three-wire connector on the PCB assembly to the connector
on the end flange.
21. Replace the desiccant pack.
22. Carefully install the end flange into the pressure housing. Make sure that the O-rings
are not twisted and the wires are not pinched.
23. Install the 10-32 screws again to attach the end flange to the pressure housing.
Operation and maintenance
8

24. Examine the pressure relief plug and O-rings. Clean or replace as necessary.
25. Verify that the voltage between contacts 1 and 2 on the bulkhead connector is
correct.
2.3 Regular maintenance
Alkaline battery packs require very little maintenance. Protect the unit from impact, flush
with fresh water after each deployment, and store it with the dummy connectors to extend
the life of this unit. Make sure that the O-rings on the end flange and the pressure relief
valve are pristine. Use the manufacturer-supplied Dow-Corning DC-111 to lubricate new
O-rings.
Pre-deployment maintenance
Inspect the pressure housing for any damage. Deep cuts or scratches weaken the
housing and reduce the depth at which the unit can safely operate. In addition, make sure
that—
• the connector is firmly seated and the lock collar is tight.
• the anode is not too corroded.
• the pressure relief valve is seated correctly.

Section 3 General information
WARNING
This product can expose the user to chemicals with silica, crystalline (airborne particles of
respirable size), which is known to the State of California to cause cancer and birth defects or
other reproductive harm. For more information, go to www.P65Warnings.ca.gov.
3.1 Warranty
Refer to the manufacturer's website for warranty information (seabird.com/warranty).
3.2 Service and support
The manufacturer recommends that sensors be sent back to the manufacturer annually to
be cleaned, calibrated, and for standard maintenance.
Refer to the website for FAQs and technical notes, or contact the manufacturer for
support at [email protected]. Do the steps below to send a sensor back to the
manufacturer.
1. Complete the online Return Merchandise Authorization (RMA) form or contact the
manufacturer.
Note: The manufacturer is not responsible for damage to the sensor during return shipment.
2. Remove all batteries from the sensor, if so equipped.
3. Remove all anti-fouling treatments and devices.
Note: The manufacturer will not accept sensors that have been treated with anti-fouling
compounds for service or repair. This includes AF 24173 devices, tri-butyl tin, marine anti-
fouling paint, ablative coatings, etc.
4. Use the sensor's original ruggedized shipping case to send the sensor back to the
manufacturer.
5. Write the RMA number on the outside of the shipping case and on the packing list.
6. Use 3rd-day air to ship the sensor back to the manufacturer. Do not use ground
shipping.
7. The manufacturer will supply all replacement parts and labor and pay to send the
sensor back to the user via 3rd-day air shipping.
