Configuration with SENS Setup Utility
Use the SENS Setup Utility to program the charger with custom settings rather than using the keypad.
Custom configuration is typically completed by OEMs, qualified dealers/distributors, and packagers. The
setup utility allows configuration of all charger settings including alarm relay assignments.
9.11.1.
Connect SENSbus Adapter
Communication between a computer and the charger using the SENS Setup Utility requires
connection of the SENSbus Adapter (shipped with SENS Setup Utility kit). Models with the
optional TCP/IP circuit board include an internal SENSbus Adapter and do not require connection
of a separate device. Connect the provided USB cable from the USB port on a PC to the SENSbus
Adapter port labeled “USB.” Connect the provided network cable from the SENSbus Adapter RJ-
45 port labeled “SENSbus” to the RJ-45 port on the charger. Two SENSbus RJ-45 ports are
provided on the inside panel between the AC and DC connections (see Figures 1-3 for location in
charger). The ports are in parallel and either port may be used for the SENSbus Adapter
connection. See the SENS Setup Utility user manual for information on configuring the charger.
9.12.
Temperature Compensation
The charger is temperature compensated to match the negative temperature coefficient of the battery.
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 16).
The charger automatically includes local temperature compensation using internal on-board sensors.
Remote temperature compensation is enabled when an optional external sensor is located at the
batteries and connected to the remote temperature sensor terminal block in the charger (see
section
6.6
for connections). Chargers with multiple output terminals include multiple remote
temperature sensor terminal blocks (connect one sensor for each output). Remote temperature
compensation is required for ultracapacitor charging and 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. The temperature Compensation slope for
ultracapacitors is set by the factory and is not adjustable. Temperature compensation is disabled by
connecting a short across the remote temperature sensor terminal block(s), 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.
