Installing the Battery Temperature Sensor

Battery Temperature
Sensor Port (RJ11)
RJ11 jack
Note: If other Xanbus
connected components supply
a BTS or are BTS enabled, it is
not necessary to install all of
them at once. Only one BTS
needs to be installed.
However, if multiple
battery-strings are being used
to form a battery bank, multiple
sensors can be installed. In
this case, the system will use
the highest temperature from
all the inputs as its operational
parameter.

The Battery Temperature Sensor (BTS) port is for connecting to the Battery Temperature
Sensor, which regulates battery charging based on battery temperature. Installing a sensor
extends battery life by preventing overcharging in warm temperatures and undercharging
in cold temperatures. This port is also considered part of the DC interface (see Figure
2-11).
To install the Battery Temperature Sensor:
1. Pass the end of the Battery Temperature Sensor cable through a conduit hole and
insert the Battery Temperature Sensor plug into the Battery Temperature Sensor port.
2. Route the cable to the battery enclosure and connect the ring terminal on the Battery
Temperature Sensor directly to a battery terminal (recommended), or use the adhesive
backing on the sensor back to attach the sensor to any side of the battery to be
monitored.
If using the adhesive backing, install the Battery Temperature Sensor on the side of
the battery below the electrolyte level. It is best to place the sensor between batteries
and place the batteries in an insulated box to reduce the influence of the ambient
temperature outside the battery enclosure.
