SBE 17plus V2 Searam Recorder & Auto Fire Module

Auxiliary equipment for use with SBE 9plus CTD and SBE 32 Carousel Water Sampler, allowing for autonomous operation without conducting winch cable.

The SBE 17plus V2 Searam provides power to and saves data from the SBE 9plus CTD (and integrated auxiliary sensors), without the need for conducting winch cable. The Searam includes Auto-Fire capability: when integrated with an SBE 32 Carousel Water Sampler, users can collect water samples at pre-programmed depths and record 9plus CTD data with one autonomous system. The Searam is typically installed in the CTD cage with the 9plus CTD; other mounting options are possible for Compact Carousels (SBE 32C) or custom applications.

The Searam’s auto-fire feature monitors pressure data transmitted by the 9plus in real-time, fires bottles on upcast at pre-defined pressures (depths), and records a firing confirmation for each bottle fired.

Each time the Searam is switched on by pushing in the magnetic switch, a file header containing date, time, and cast number is written to memory. The Searam’s memory can record full-rate CTD and 8-channel auxiliary sensor data (24 scans/sec) for approximately 6 hours. When desired, the data is uploaded to a computer. Sea-Bird software converts the raw CTD data and bottle fire confirmations and creates a CTD data file and a bottle data file.

Do I need to remove batteries before shipping my instrument for a deployment or to Sea-Bird?

Alkaline batteries can be shipped installed in the instrument. See Shipping Batteries for information on shipping instruments with Lithium or Nickel-Metal Hydride (NiMH) batteries.

What are the recommended practices for connectors - mating and unmating, cleaning corrosion, and replacing?

Mating and Unmating Connectors:

It is important to prepare and mate connectors correctly, both in terms of the costs to repair them and to preserve data quality. Leaking connectors cause noisy data and even potential system shutdowns. Application Note 57: Connector Care and Cable Installation describes the proper care and installation of connectors for Sea-Bird instruments. The Application Note covers connector cleaning and cable or dummy plug installation, locking sleeve installation, and cold weather tips.

Checking for Leakage and Cleaning Corrosion on Connectors:

If there has been leakage, it will show up as green-colored corrosion product. Performing the following steps can usually reverse the effect of the leak:

  1. Thoroughly clean the connector with water, followed by alcohol.
  2. Give the connector surfaces a light coating of silicon grease.

Re-mate the connectors properly — see Application Note 57: Connector Care and Cable Installation and 9-minute video covering O-ring, connector, and cable maintenance.

Replacing Connectors:

  • The main concern when replacing a bulkhead connector is that the o-rings on the connector and end cap must be prepared and installed correctly; if they are not, the instrument will flood. See the question below for general procedure on handling o-rings.
  • Use a thread-locking compound on the connector threads to prevent the new connector from loosening, which could also lead to flooding.
  • If the cell guard must be removed to open the instrument, take extra care not to break the glass conductivity cell.

What are the recommended practices for inspecting, cleaning, and replacing o-rings?

Inspecting and Cleaning O-Rings and Mating Surfaces:

  1. Remove any water from the o-rings and mating surfaces with a lint-free cloth or tissue.
  2. Visually inspect the o-rings and mating surfaces for dirt, nicks, cuts, scratches, lint, hair, and any signs of corrosion; these could cause the seal to fail. Clean the surfaces, and clean or replace the o-rings as necessary.
  3. Apply a light, even coat of 100% silicon o-ring lubricant (Parker Super O Lube) to the o-rings and mating surfaces. For an end cap o-ring, a ball of lubricant the size of a pea is about all that is needed. Too much lubricant can cause the seal to fail as much, if not more, than no grease. Do not use petroleum-based lubricant (car grease, Vaseline, etc.), as it will cause premature failure of the rubber.
    CAUTION: Parker makes another product, Parker O Lube, that is petroleum-based. Do not use this product; verify that you are using Parker Super O Lube.
  4. After lubricating the o-ring, immediately reassemble the end cap or connector, verifying that no hairs or lint have collected on the lubricated o-ring.

Replacing O-Rings:

  • End Cap O-Rings: We recommend scheduled replacement of end cap o-rings approximately every 3 years, to prevent leaks caused by normal o-ring wear.
  • Connector O-Rings: Replacing connector o-rings requires de-soldering and re-soldering the connector wires, which makes it a more difficult task. Therefore, we recommend replacement of connector o-rings when needed, not on a routine, scheduled basis.

Additional Information:

  • 9-minute video covering O-ring, connector, and cable maintenance.
  • Short, silent video of application of lubricant to o-ring.
  • Short, silent video of application of lubricant to o-ring mating surface (note the use of a plastic dental syringe — no sharp points to scratch the housing — to apply the lubricant).

How do instruments handle external power if internal batteries are installed?

Most Sea-Bird instruments that are designed to be powered internally or externally incorporate diode or'd circuitry, allowing only the voltage that has the greater potential to power the instrument. You can power the instrument externally without running down the internal batteries. This allows you to lab test using external power that has higher voltage than the internal batteries, and then deploy using internal power, knowing that the internal batteries are fresh.

For the SBE 25plus, if external power of 14 volts or higher is applied, the 25plus runs off of the external power, even if the main battery voltage is higher.

Do you recommend a particular brand of alkaline D-cell batteries?

For Sea-Bird instruments that use alkaline D-cells, Sea-Bird uses Duracell MN 1300, LR20. While rare, we have seen a few problems with cheaper batteries over the years: they are more likely to leak, may vary in size (leading to loose batteries causing a bad power connection), and may not last as long.

What is the function of the zinc anode on some instruments?

A zinc anode attracts corrosion and prevents aluminum from corroding until all the zinc is eaten up. Sea-Bird uses zinc anodes on an instrument if it has an aluminum housing and/or end cap. Instruments with titanium or plastic housings and end caps (for example, SBE 37 MicroCAT) do not require an anode.

Check the anode(s) periodically to verify that it is securely fastened and has not been eaten away.

SBE 17plus Connector Selections — MUST SELECT ONE
17P.x1 XSG/AG connectors

Match connector type to those on 9plus CTD & SBE 32 or 32C Carousel Water Sampler you will be using with 17plus. Wet-pluggable connector options include wet-pluggable connectors on 17plus bulkhead connectors & on data I/O & CTD/Searam cables.

Wet-pluggable connectors may be mated in wet conditions. Their pins do not need to be dried before mating. By design, water on connector pins is forced out as connector is mated. However, they must not be mated or un-mated while submerged. Wet-pluggable connectors have a non-conducting guide pin to assist pin alignment & require less force to mate, making them easier to mate reliably under dark or cold conditions, compared to XSG/AG connectors. Like XSG/AG connectors, wet-pluggables need proper lubrication & require care during use to avoid trapping water in sockets.

We strongly recommend wet-pluggable connectors for 17plus. You must connect to 17plus on deck after each deployment to re-arm auto-fire mechanism. Wet-pluggable connectors provide better reliability given potential for rain, wave splash, etc. (If cost is an issue, an alternative is to use a jumper cable, with RMG connector at 17plus end and wet-pluggable connector at other end, to plug into wet-pluggable data I/O cable. This allows you to mate / unmate wet-pluggable connector to arm system. Contact Sea-Bird for quote for jumper cable.)
