Figure 3.1 Main components of the buoy 1 Radio transceiver 2 Solar panel (behind the battery box) 3 Battery box 4 DO sensor, cleaning brush, and cleaning dispenser Deployment Considerations l l l Ensure that the DO sensor and bush are submerged in the pond sufficiently away from the pond's edge, and above the bottom of the pond. Carry the buoy by the float. Do not carry the buoy by the conduit or PVC pipes because it will cause damage. Anchor the buoy.
RDO Titan Probe The RDO Titan Probe ships pre-installed on the buoy. The RDO Titan Probe has an optical dissolved oxygen (DO) and temperature sensor, which deliver accurate data across a wide measurement range. The probe features a titanium body, removable cable, and internally stored calibration. The RDO Titan system consists of the following components. Figure 4.
Replace the RDO Classic Sensor Cap The RDO Classic Sensor Cap has a 1-year typical life, and a 15-month total life, after the instrument takes its first reading. The cap shelf life is 36 months from date of manufacture. The buoy is shipped with the RDO Titan and RDO Classic Sensor Cap already installed. The following procedure should be used only when you need to replace the RDO Classic Sensor Cap. It is not necessary for the first installation. 1. Remove the lid from the battery box. 2.
Figure 4.6 RDO Titan Probe with RDO Classic Sensor Cap removed 8. Inspect the sensor lens. If necessary, clean the lens with a lint-free lens cloth. Avoid touching or cleaning the lens with anything other than the lens wipe supplied in the RDO Replacement Sensor Kit. 9. Remove the existing O-rings from the probe. Ensure there is no moisture in the Oring grooves. 10. Use your finger to apply a very thin layer of lubricant around the O-ring grooves. 11. Place the O-rings on the probe.
Adjust the Wiper Brush It is important that the wiper brush be clean and properly adjusted. 1. Remove the lid from the battery box. 2. Remove the red lead from the battery. 3. Rotate the cleaning brush so the bristles face 180 degrees away from the probe tip. 4. Ensure that the brush is aligned with the center of the RDO Classic Sensor cap. If necessary, use a 3.32 in. Allen hex wrench to loosen the set screw on the brush, adjust the brush position, and tighten the set screw. 5.
Installing the Cleaning Tablet 1. Remove the cap from the bottom of the bush motor housing tube. 2. Place a new chlorine or bromine tablet in the cap. 3. Replace the cap. Figure 5.
Buoy Transceiver Overview The transceiver consists of the following items. l A microprocessor that is programmed to take sensor readings at given intervals l A radio module that transmits the sensor readings to the host computer l A desiccant pack In between the readings, the radio module operates in sleep mode, enabling the buoy to operate with lower power consumption. Figure 6.
l l l It is a binary switch The address is the sum of the values of the binary switches that are in the "on" or "up" position. Figure 6.2 If you change the buoy address after powering the system on, it is necessary to disconnect and reconnect power for the address change to take effect. Dip Switch Addressing Explanation and Examples The dip switch panel is located in between the microprocessor and the wiring connections. Figure 6.1 Dip switches 1 through 7 have a binary value.

Cleaning, Maintenance, and Storage Storage Recommendations If you remove the buoy from service seasonally, remove the battery from the buoy and store it separately. If the sensor cap will expire before you redeploy the unit, discard the cap and place a red dust cap over the end of the sensor. If you do not have a dust cap, keep the sensor cap in place. The sensor lens on the probe must always have adequate protection. When you redeploy the buoy after a period of storage, use a new RDO Classic Sensor Cap.
Cleaning the Probe Body With the sensor cap installed on the probe, gently scrub the probe body with a softbristled brush or nylon dish scrubber. Use Alconox to remove grease or other matter. Soak in vinegar and DI water to remove mineral deposits or extensive fouling as previously described. Replacing the Sensor Cap See page 10.
