Configuration and Monitoring with SENS Setup Utility

The SENS Setup Utility is used to monitor, configure, and troubleshoot SENS chargers. Download the
SENS Setup Utility software at

www.sens-usa.com

. The setup utility allows configuration of all charger

settings including alarm relay assignments. Communication between a computer and the charger using
the SENS Setup Utility requires connection of a Cat5 minimum RJ45 cable between the ethernet port on
the charger and the ethernet port on the computer (see section

).

Connect using the “SENSnet”

option in the SENS Setup Utility. See the SENS Setup Utility user manual for information on connecting
to and communicating with the charger.

Temperature Compensation

The charger is temperature compensated to match the negative temperature coefficient of the battery.
A SENS remote battery monitor is required for this functionality.  When temperature compensation is
active, the output voltage will increase slightly as temperature decreases, decrease as temperature
increases, and is clamped at 0°C (32°F) and +40°C (122°F) to protect against extremely high or low
output voltage (see Figure 11).

The charger automatically includes local temperature compensation using internal on-board sensors.
Remote temperature compensation is enabled when the external sensor is located at the batteries and
connected via the optional SENS remote battery monitor. Remote temperature compensation should
be used in applications where battery and charger are located in different ambient conditions.
Temperature Compensation is set to a slope of

‐

0.18% per °C by default for operation with batteries.

Temperature compensation is disabled by using the keypad or by setting the temperature
compensation slope to zero using the SENS Setup Utility. The temperature present at a sensor (local or
remote) is displayed on the front panel LCD. Actual battery temperature is only displayed if the optional
remote temperature sensor is connected to the charger and placed at the batteries.
