JANUARY 2010 - TD 220a DEPLOYMENT GUIDE, RDCP600 Page 71Reliable solutions1. Remove the instrument from the pressure case by releasing the two c-clamps at the topend plate and lift up the instrument.2. Unscrew the correct sealing plug at the top end plate. Loosen the set screw that goes withthe sensor position. Do not unscrew the set screw completely and remove it, as it mightbe lost.3. Pull up the sealing plug. Clean the boreholes.4. Inspect the O-rings of the new sensor.5. Connect and tighten the new sensor.6. Remove the sensor board connector cover from the instrument by unscrewing the twoscrews at the top of the sensor board cover.7. Plug the electronic cable into the correct channel at the electronic board If the new sensor is a Temperature sensor, it must be connected to connectorchannel 2 If the new sensor is a Conductivity sensor 3919, Pressure sensor 4017, Oxygenoptode or Turbidity sensor it must be connected to the connector named channel 4,5 or 6 on the sensor board.IMPORTANT!Make sure that the sensors and the c-clamps are well tightened to ensure that no water willinfuse the system. Do not over tight as this will damage the sensors and the clamps.Always update the Calibration Coefficients and other sensor information when a new sensor isinstalled (Refer the Sensor Configuration page).4.8.2 Procedure for disconnecting a sensorThe Compass Tilt Sensor and the Quartz Pressure Sensor must be connected at the manufacturerdue to calibration procedures and to prevent water infusing the instrument. If your deploymentdoes not need the Heading, Pitch and Roll parameters, we recommend that you set fixedparameters in the Compass/Tilt sensor configuration page. For disconnection of other sensors,please follow the listed procedure:1. Remove the instrument from the pressure case by releasing the two c-clamps at the topend plate and lift up the instrument.2. Remove the sensor board connector cover from the instrument by unscrewing the twoscrews at the top of the sensor board cover.3. Unplug the electronic cable from the correct channel or terminal. |
