2. Preparing for Deployment

The ECO-IM ships with batteries packaged separately to comply with US and international laws governing the shipment of Dangerous/Hazardous goods on commercial aircraft.

2.1 Installing Batteries

Remove the modem end cap

1. Ensure the outside of the modem end cap and housing are dry. Remove any water at the seam between them.

2. Remove the two flat Phillips-head titanium machine screws.

3. Remove the end cap by pulling firmly and steadily on the plastic cable mounting, bracket/inductive coupler. It may be necessary to twist or rock the end cap back and forth or use a non-marring tool on the edge of the cap to loosen it.

4. The end cap is electrically connected to the

electronics with a 3-pin Molex connector. Hold the wire cluster near the connector and pull gently to detach the sockets from the pins.

5. Remove any water from the O-ring mating surfaces inside the housing with a lint-free cloth or tissue.

6. Put the end cap aside, being careful to protect the O-rings from damage or contamination.

Remove the battery pack assembly from the housing

1. Loosen the captured screw from the battery cover plate, using the 7/64-inch Allen wrench included with the shipment.

2. Lift the battery pack assembly straight out of the housing, using the handle. Keep the handle in an upright position

ECO FLNTURTD-IM User’s Guide (flnturtdim) Revision A 15 April 2011 3

3. Unscrew the cover plate from the battery pack assembly. Remove the two O-rings from the grooves.

4. Insert each battery into the holder

according to the + and - labels. 5. Re-roll the two O-rings on the outside of

the battery pack into place in the grooves: they compress the side of the battery pack and hold the batteries tightly in place in place.

Reinstall battery pack coverplate

Place the handle in an upright position. Screw the red cover plate onto the battery pack assembly. Ensure the cover is tightly screwed on to provide a reliable electrical contact.

Replace the battery pack assembly in the housing

1. Align the D-shaped opening in the cover plate with the D-shaped notch on the shaft. Lower the assembly slowly into the housing, and once aligned, push gently to mate the banana plugs on the battery compartment bulkhead with the lower PCB. A post at the bottom of the battery compartment mates with a hole in the battery pack’s lower PCB to prevent improper alignment.

2. Secure the assembly to the shaft with the

captured screw, using the 7/64-inch Allen wrench. Ensure the screw is tight to provide a reliable electrical contact.

Reinstall the modem end cap

1. Remove any water from the O-rings and mating surfaces in the housing with a lint-free cloth or tissue. Inspect the O-rings and mating surfaces for dirt, nicks, and cuts. Clean as necessary. Apply a light coat of O-ring lubricant (Parker Super O Lube) to O-ring and mating surfaces.

2. Plug the socket end of the Molex connector onto the pins, with the flat portion of the socket end against the flat portion of the “D” cutout. Verify the connector is properly aligned: a backward connection will prevent communication with the computer.

3. Carefully fit the end cap into the housing until the O-rings are fully seated.

4. Reinstall the 2 flat Phillips-head titanium screws to secure the end cap.

2.2 Mooring Cable Wiring Requirements The standard ECO-IM clamp can accommodate mooring cables up to 16 mm (0.63 in.) in diameter. Clamps for specific diameters are available, or can be supplied on a custom basis. An optional large toroid end cap with wire guide and heavy duty titanium mounting clamp is also available for 38 mm (1.5 in.) mooring cables. Suitable mooring cables use steel wire rope with a polypropylene or polyethylene-insulating jacket. The system operates without data errors using up to 6000 m (19,000 ft) of 3 mm (0.12 in.) or larger cable.

• The mooring cable must provide connection to seawater ground below the deepest IM instrument. Terminating the wire with a metallic eye or clevis readily provides this connection.

• The mooring cable must also provide for connection to the IMM.

In a direct connection (typical cable-to-shore applications), the bottom end of the wire is grounded to seawater, and the top end remains insulated to the connection to the IMM. A second wire from the IMM connects to the seawater ground, completing the circuit. In typical surface buoys it is often preferable to connect the jacketed mooring wire to the buoy with a length of chain, grounding the jacketed wire to seawater at each end. An Inductive Cable Coupler (ICC) connects the IMM to the jacketed wire above the uppermost IM instrument and below the point where the wire is grounded.

The ECO-IM in the figure below is installed as the SBE 37-IM.

2.3 Attaching the ECO-IM to Mooring Cable

1. Open each mounting bracket by unthreading the two large titanium hex bolts.

2. Place the insulated mooring

cable inside the brackets’ grooves.

3. Reinstall each bracket half

with the hex bolts.

4. Verify the two halves of the modem coupling toroid have come together evenly, and

that the mounting clamp is secure. 5. Verify the hardware and external fittings are secure.

3. ECO-IM Overview The FLNTURTDB-IM, hereby referred to as an ECO-IM, melds a Sea-Bird Inductive Modem Module (IMM) with a WET Labs ECO optical sensor. All communication to the ECO-IM is performed via the IMM end of the instrument. Please review the Sea-Bird IMM documentation (Inductive Modem Module Configuration and Calibration Manual) to gain a clear understanding of how a Sea-Bird IMM-based inductive mooring is set up and used. A basic understanding of the IMM communication protocols is required before attempting to use an ECO-IM. The ECO-IM is configured to operate in IM Service Mode as described in the IMM documentation. With the standard shipping configuration, a system controller must be used to command the ECO-IM to turn on the optics head and to take a sample. When the onboard IMM receives a sample command, the optics electronics is turned on, a sample is taken, and the optics electronics is turned off.

Caution

Attempting to configure and operate the ECO-IM in one of the other operating modes available to the IMM may result in communication conflicts between the ECO and IMM which could result in greatly

reduced battery life and the loss of data.

ECO-IM’s are always shipped with a DeviceID=11.

3.1 Initial Checkout Once the battery pack has been installed on the ECO-IM, it is ready for testing. For out of water testing, set up a 100 ohm test loop as shown in Sea-Bird Application Notes 78 and 80, or in the Inductive Modem Module Configuration and Calibration Manual. Once the test inductive loop is setup, the user may trigger sample from the ECO-IM using the GData, SendGData, GetReply, and Direct commands as shown in Appendices D–F. Use the direct sampling from Appendix F. With communication established, verify the output from the ECO. Remove the protective end-cap. Hold the supplied the fluorescent stick 1–4 cm above the optical paths in an orientation that maximizes exposure of the stick. (Parallel with the beams, not intersecting them). The signal will increase toward saturation (maximum value on characterization sheet). To check dark counts, place a piece of electrical tape over the light source on the optics face. Once the battery pack is installed in the ECO-IM and the end-cap properly installed, the unit is ready for submersion and subsequent measurements. Some consideration should be given to the package orientation. Do not face the sensor directly into the sun or other bright lights. For best output signal integrity, locate the instrument away from significant EMI sources.

Other than these basic considerations, one only needs to make sure that the unit is securely mounted to whatever lowering frame is used and that the mounting brackets are not damaging the unit casing.

3.2 Deployment Command Options The ECO-IM is set up to operate in the IM Service mode, which means each sample must be triggered by the main inductive mooring system controller. There are two commands to perform buffered data sampling and one to perform direct sampling.

3.2.1 Buffered Sampling

The two commands that can be used to trigger a buffered sample are SendGData and GData. The SendGData command take a “synchronized” sample by every instrument on an inductive mooring. When the SendGData is issued, every instrument on the inductive mooring will respond by taking a sample. The SendGData command is issued at the IMM prompt: IMM> SendGData The GData command is used to instruct a single instrument (ECO-IM) to take a sample. Using the GData command allows the system controller to control how many samples each instrument takes, thereby maximizing the battery or memory capacity of each individual instruments. The GData command is issued with the individual ID format: IMM>!XXGData where XX is the ECO-IM Device ID. Out of the box, the ECO-IM has a DeviceID=11 and will respond to !11GData. When either the SendGData or GData commands are used, the ECO-IM will take a sample and store it in the GReply buffer. An individual GetReply command is used to retrieve the data from the ECO-IM’s GReply buffer. The command format is: !XXGetReply where xx is the ECO-IM Device ID. Out of the box, the ECO-IM has DeviceID=11 and will respond to !11GetReply. Example GData and GetReply sample sequences can be found in Appendices D and E.

3.2.2 Direct Sampling

A sample may be retrieved directly from the ECO-IM by issuing it a host command such as #XX$Run, where XX is the Device ID. This will cause the ECO-IM to power up the optics electronics, take a sample, immediately transmit the sample output, and turn off the optics power. An example of direct sampling can be found in Appendix F.

ECO FLNTURTD-IM User’s Guide (flnturtdim) Revision A 15 April 2011 9

3.2.3 Buffered vs. Direct Sampling

Buffered sampling has the advantages of: a. Storing the data in the IMM’s GReply buffer. This allows the system controller to

retrieve the data at its convenience and ask the ECO-IM to retransmit the data if the original data transmission is corrupted without having to repower the optics and taking a second sample.

b. Allows synchronized sampling. The system controller can issue a SendGData command and instruct all the instruments on the mooring to take a sample simultaneously. The data is the retrieved from each individual instrument.

Disadvantage:

GDataReply tags are used to bracket the data record and these need to be parsed out of the data for processing. (See Appendix D for an example).

Direct sampling has the advantages: a. It provides a cleaner, tag free output record. (See Appendix F for an example) b. Does not require a GetReply command to be issued to the ECO-IM. Disadvantages: a. It cannot be used for synchronized sampling. b. If a sample is corrupted during data transmission, a second sample must be taken,

waiting limited battery resources.

3.2.4 Changing the ECO-IM Sampling Setup

To change any of the optical setup parameters, the user must gain manual control over the ECO-IM power, change the reply termination character, turn on the ECO-IM power, change the ECO-IM optics setup, return the ECO-IM IMM to its default. An example of this process is found in Appendix G.

3.2 Upkeep and Maintenance WET Labs recommends that ECO meters be returned to the factory annually for cleaning, calibration and standard maintenance. Contact us or visit our website for details on returning meters.

After each cast or exposure of the instrument to natural water, flush with clean fresh water, paying careful attention to the sensor face. Use soapy water to cut any grease or oil accumulation. Gently wipe clean with a soft cloth. The sensor face is composed of ABS plastic and optical epoxy and can easily be damaged or scratched. Avoid direct electrical connection of the meter’s titanium pressure housing to mooring or other dissimilar metal hardware.

4. Data Analysis Data from the ECO-IM represents raw output from the sensor. Applying linear scaling constants, this data can be expressed in meaningful forms of chlorophyll fluorescence and NTUs.

4.1 Scale Factor The scale factor is factory-calculated by obtaining a consistent output of a solution with a known concentration, then subtracting the meter’s dark counts. The scale factor, dark counts, and other characterization values are given on the instrument’s characterization sheet.

Chlorophyll For chlorophyll, WET Labs uses the chlorophyll equivalent concentration (CEC) as the signal output using a fluorescent proxy approximately equal to 25 µg/l of a Thalassiosira weissflogii phytoplankton culture.

Scale Factor = 25 µg/l ÷ (Chl Equivalent Concentration – dark counts)

For example: 25 ÷ (3198 – 71) = 0.0080.

NTU

Scale Factor = xx ÷ (meter output – dark counts), where xx is the value of a Formazin concentration.

For example: 12.2 ÷ (2011 – 50) = 0.0062. The scale factor is then applied to the output signal to provide the direct conversion of the output signal to chlorophyll concentration. WET Labs supplies a scale factor on the instrument-specific calibration sheet that ships with each meter. While this constant can be used to obtain approximate values, field calibration is highly recommended.

4.2 Output To obtain “calibrated” output, subtract a digital offset value from output when measuring a sample of interest and multiply the difference by the instrument’s (linear) scale factor.

Chlorophyll:

[Chl]sample = (Coutput – Cdc) * Scale Factor where

[Chl]sample = concentration of a chlorophyll sample of interest (µg/l) Coutput = output when measuring a sample of interest (counts)

Cdc = dark counts, the measured signal output of meter in clean water with black tape over the detector

Scale factor = multiplier in µg/l/counts.

ECO FLNTURTD-IM User’s Guide (flnturtdim) Revision A 15 April 2011 11

NTU:

[NTU]sample = (NTUoutput – Cdc) * Scale Factor where

[NTU]sample = concentration of NTU solution NTUoutput = output when measuring a sample of interest (counts)

Cdc = dark counts, the measured signal output of meter in clean water with black tape over the detector Scale factor = multiplier in NTU/counts.

5. Characterization and Testing ECO-IM is configured for measurement ranges given in the specifications. Gain selection is performed by setting several gain settings inside the instrument, and running a dilution series to determine the zero voltage offset and to ensure that the dynamic range covers the measurement range of interest. The dilution series also establishes the linearity of the instrument’s response. As is the case with other fluorometers, perform a detailed characterization to determine the actual zero point and scale factor for your particular use. A “best practice” for moored applications is to periodically obtain a “grab” sample from near the mooring as a check for the validity of the moored meter’s output. The tests below ensure the meter’s performance. 1. Dark counts: The meter’s baseline reading in the absence of source light is the dark

count value. This is determined by measuring the signal output of the meter in clean, de-ionized water with black tape over the detector.

2. Pressure: To ensure the integrity of the housing and seals, ECOs are subjected to a wet

hyperbaric test before final testing. The testing chamber applies a water pressure of at least 50 PSI.

3. Mechanical Stability: Before final testing, the ECO meters are subjected to a mechanical

stability test. This involves subjecting the unit to mild vibration and shock. Proper instrument functionality is verified afterwards.

4. Electronic Stability: This value is computed by collecting a sample once every second for twelve hours or more. After the data is collected, the standard deviation of this set is calculated and divided by the number of hours the test ran. The stability value must be less than 2.0 counts/hour.

5. Noise: Noise is computed from a standard deviation over 60 samples. These samples are collected at one-second intervals for one minute. A standard deviation is then performed on the 60 samples, and the result is the published noise on the calibration form. The calculated noise must be below 2 counts.

Appendix A: Battery Endurance The battery pack has a nominal capacity of 10.6 Amp-hours. This is less than the Saft factory capacity rating of 14.7 Amp-hours because the battery holder includes voltage up-conversion circuitry that consumes some battery capacity. For planning purposes, WET Labs recommends using a conservative value of 8.8 Amp-hours.

Current Consumption Current draw during data acquisition is 40 mA. Current draw during data transmission is 1.4 mA @ 9600 baud. Assuming the fastest practical interrogation scheme (wake all meters on mooring, send GData, send Dataii or !iiData to each meter, and power off all meters), the communications current is drawn for approximately 0.5 seconds per meter on the mooring. Each meter on the mooring draws this current while any of the meters are being queried to transmit data. Other interrogation schemes require more time. Sleep current is 0.026 mA. Note that battery endurance is highly dependent on the user-programmed sampling scheme.

Appendix E: ECO-IM Data Sampling Using SendGData In this sample sequence, the system controller uses the global command SendGData to have a remote ECO-IM to take a sample, and the command GetReply to retrieve the sample data from the remote ECO-IM’s GReply buffer. The ECO-IM Device ID = 11. The IMM> is the system controller’s IMM prompt. Anything on the same line as but following the IMM> is what the system controller sends to its local IMM. Everything else is execution tags and /or data from the remote ECO-IM. Anything after // is a comment and is not part of the command/response sequence

Appendix F: ECO-IM Data Sampling Using a “Host” Command In this sample sequence, the system controller uses a “Host” command to have a remote ECO-IM to take a sample and transmit its results. (Host as defined in the IMM documentation.) The ECO-IM Device ID = 11. The IMM> is the system controller’s IMM prompt Anything on the same line as but following the IMM> is what the system controller sends to its local IMM. Everything else is system controller IMM and remote ECO-IM execution tags.

Appendix G: Changing ECO-IM Sample Setup In this sequence, the ECO-IM will undergo the following steps:

A. Change the IMM configuration so the ECO stays powered (Required in order to change the ECO sample parameters)

B. Change the sample averaging from 30 to 32 C. Change the sample size from 3 to 1 D. Take a direct sample to verify the setup is correct E. Change the IMM configuration so the ECO power is switched with the IMFlag F. Verify the sample and data retrieval functions as expected.

The ECO-IM Device ID = 11. The IMM> is the system controller’s IMM prompt. Anything on the same line as but following the IMM> is what the system controller sends to its local IMM.
