Preparing the ADCP
To connect the battery:
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. Connect the Red/Black 2-pin battery cable to the 2-pin
battery cable connector.
After power is applied (long beep), there is a 10 to 15 second
delay before the network is available (short beep); If you do not
hear the beeps, repeat/check step 5 before continuing.
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.
