When year-round deployment of a NexSens CB-Series buoy is not possible or desired, the following maintenance steps are required to ensure that the system is best prepared for the next sampling season.
- The buoy should be stored in a relatively dry environment that is above freezing. Cold temperatures can weaken the PVC joints for deployment pipes.
- Disconnect the 6-pin solar panel plug from the buoy’s SOLAR port as soon as the buoy is taken out of the water. This plug acts as a switch supplying power from the equipped batteries to the data logger. If the panel is left connected over a long period of time during storage, the batteries will be run down and may require replacement as a result.
- While the buoy is stored, it is recommended that its batteries are topped off approximately every 2-3 months either by using a CB-PW-AC float charger or by moving the buoy out into the sun and reconnecting the solar panel. This will keep the system battery from self-discharging.
- Note that unless the sample and log interval of the logger is changed, data will be logged during this time. If having a span of invalid data stored on the data logger memory is not desired, change this interval before charging.
