NexSens Technology X2-CB, User Manual

4. Secondary Power – Any power supplied to an X2 through the secondary pins on a UW-6 plug connector
will be registered as Secondary Power.
Secondary power is typically only utilized by X2-SDL systems running on internal D-cell batteries. All other
systems will return ~0V (as shown), indicating that no secondary power input is present.
5. Sensor Power – The X2 regulates power to its sensor ports. Depending on the state of the system’s
primary or secondary power, the X2 will boost or reduce sensor power to maintain a nominal 12V output. In
practice, these values tend to range from 11.8V-12.2V.
6. Total System Current – The total power consumption of the electronics in the system (sum of the data
logger and external sensors) is monitored by the X2.
It is best to disregard the status icon designation for this parameter. Depending on the system setup
(telemetry type, number of sensors, sensor types, etc.) and other system conditions (power supply voltage),
a ‘normal’ current draw will vary widely between systems. Instead, use this to establish a baseline and
investigate system health if a significant change is observed.
7. Sensor Current – The current draw, at 12V, of all external sensors and devices connected to an X2 logger.
As with total current, disregard the status icon and use historical data to establish a baseline range for the
system’s sensor current.
8. Internal Pressure* – Reports the air pressure inside an X2 data logger housing. Useful for identifying vent
obstructions or excessive outgassing from charging system batteries.
* Note that X2 systems delivered any time after mid-2018 will not have an internal pressure sensor due to a
parts shortage-induced design change. Dashes will occupy the value field as a result.
