4.7
Buoy Deploying: Downwards facing RDCP600
An illustration of the RDCP deployed using a buoy is given in Figure 4-5.
An anchor chain with an anchor at the end is mounted to the buoy cable to keep the instrument in
one position.
The anchor dimension and weight must be suitable to match the conditions at the location.
We recommend an anchor of about 450kg for deployments in rough conditions.
Prepare the anchoring equipment and the length of the mooring line according to the deployment
depth.
Lower the anchor and chains gently until the anchor rests on the bottom.
1.
Let the buoy go overboard.
2.
Be careful not to harm the superstructure in this operation.
Aanderaa offers a number of communication devices for communication with the Buoy:
UHF/VHF, GSM, GPRS, Radio Modem, Argos Satellite, OrbCom Satellite and Iridium Satellite
system. Refer to our Brochure B136 and/or contact our Engineering department for detailed
information.

Connection and Disconnection of Sensors
An illustration of the Top end plate with all standard and optional sensors connected to it is given
in TD220c
RDCP Primer
. Except for the borehole for the Zink Anode, the other 7 boreholes in
the top end plate are all equal in diameter, allowing the user to connect a sensor in a user-optimal
location. However, there are some restrictions:
Temperature sensor 4050 and Temperature from Conductivity 3919 or Pressure 4017:
Need to
be connected to connector named
channel, 2
on the sensor board if you want to use it for
compensation.
Conductivity sensor 4019:
Conductivity sensor 4019 must be connected to the internal bus.
Turbidity sensor, Oxygen optode, Conductivity 3919 and Pressure sensor
:
These sensors are
used in channels 4,5, or 6.
An illustration of the Electronic Board is given in Figure 4-7.
4.8.1
Procedure for Connecting a Sensor
The Compass Tilt Sensor and the Quartz Pressure Sensor must be connected at the manufacturer
due to calibration procedures and to prevent water infusing the instrument. For connections of
other sensors, please follow the listed procedure (steps 1 to 8):
