The X2-SDL has flexible power input choices that provide several options in terms of type and number of power sources. Basic Requirements 5-24 VDC [+/-10%] (Reverse polarity protected) Current Draw (Typical @ 12VDC): Low power sleep: 350uA; Logger Active: 35mA; Wi-Fi Transmitting: 43mA; Cellular Transmitting: 300mA Peak Current: 500mA @ 12V for 1 […]
The following practices should be carried out when placing an X2-SDL data logger in storage for an extended period of time: Remove all D-Cell batteries inside the data logger. The battery installation procedure can be referenced for removal guidance. Batteries left inside may leak and corrode the internal compartment of the logger. Any X2-SDL left powered […]
Each X2-SDL and SDL-V2 data logger has a body tag number for identification. The long housing tube has the tag etched between the antenna and sensor bulkheads. The default name of the device on WQData LIVE will incorporate this number (see Figure 3). NexSens technical support specialists will typically request the body tag for remote […]
Performing a power cycle on an SDL data logger such as the X2-SDL is often useful for troubleshooting purposes. To cycle power on an SDL: Locate the white battery lid at the top of the SDL. Rotate the cap counter-clockwise to remove it. Note: Due to the double O-ring lid seal, this will take significant […]
The X2-SDL requires (16) D-Cell Duracell1 Alkaline batteries. 1D-cell batteries from other manufacturers may have sub-flush negative terminals which can result in poor contact and may affect the consistency of power supplied to the X2-SDL logger.
Depending on the total power demand of an X2-SDL system, the minimum acceptable operation voltage can vary. Factors such as the number and types of connected sensors, logging interval, transmission interval etc. influence the required power supply. A general rule of thumb is to consider replacing the X2-SDL’s (16) D-Cell batteries when the voltage falls […]
The battery compartment of the X2-SDL data logger accommodates (16) D-Cell Alkaline batteries for system power. These batteries should be replaced once the reported secondary power falls to 8V to avoid data collection interruption. Locate the white battery lid at the top of the X2-SDL. Rotate the lid counter-clockwise to remove it. Note: Due to […]
The X2-SDL is rated for submersion up to 200ft (~60m) depth. Note that the SDL-CAP accessory is required to fully submerge cellular or radio models containing an external antenna. The antenna port of Wi-Fi only models is epoxied closed and may be completely submerged using the standard battery lid.
Proper O-ring maintenance on an X2-SDL submersible data logger is critical to prevent moisture intrusion and achieve the full depth rating. The X2-SDL contains (3) user-servicable O-rings, all located on the white battery lid. All O-rings should be inspected during each battery change. General Maintenance Keep O-rings clear from debris that may affect even surface […]
