Preparing the ADCP
To install the D cell batteries:
1. Place the Sentinel V ADCP with the end-cap facing up. Use a soft
pad or the transducer cover to protect the ADCP.
2. Using a 4mm hex key, loosen the four M5 captured bolts on the
end-cap.
A 4mm hex key is provided in the canvas bag.
The end-cap hardware will stay attached to the end-cap.
3. Carefully lift the end-cap away from the housing. Observe how the
internal I/O cable is coiled inside the housing. It must be coiled
exactly the same way when replacing the end-cap.
A lanyard connects the end-cap to the housing to protect the
internal I/O cable. Leave the lanyard connected.
4. Let the end-cap hang from the lanyard to the side of the ADCP.
5. Remove the battery cover plate by loosening the knob (rotate
counter-clockwise).
6. Use the battery cover diagram for battery orientation and slide in
the D cell batteries. Ensure all batteries are fully seated by pushing
them down into the battery cavity. Position the cover plate over
the batteries and tighten the knob until the cover plate is flush
with the
surrounding
surface.
As the cover is installed, there is a long beep, a 10 to 15 second
delay, and then a short beep. If you do not hear the beeps,
repeat/check steps 5 and 6 before continuing.
If the battery cover is loose, the D cell batteries may make
intermittent contact or it may interfere with the end-cap
properly closing. Tighten the knob until the cover plate is flush
with the surrounding surface.
To close the system:
1. Check the O-ring for any fibers or particles. Make sure it is seated
in the groove and the surfaces are clean.
2. Verify the desiccant bag is installed and will not interfere with the
end-cap when it is installed.
TRDI recommends replacing both the O-ring and desiccant
before each deployment.
3. Match the alignment mark and beam numbers embossed on the
end-cap with the alignment mark/beam numbers embossed on the
housing to place the end-cap on the housing. Check the cables are
coiled around the inside of the housing and do not become
pinched.
4. Install all four sets of hardware until “finger-tight.”
5. Tighten the bolts in small increments in a “cross” pattern until the
split washer begins to flatten out.
6. TRDI recommends using a torque wrench to tighten the bolts to
the recommended torque value of 1.7 Nm (15 Pound-Force Inch).
If a torque wrench is not available, tighten the bolts until the split
washers are flat, and then turn the bolts ¼ turn more. Do not strip
the bolts or captive nut threads.
