Installing the Battery Temperature Sensor
Installing a Battery Temperature Sensor (BTS) is recommended for optimum
charging performance and extending battery life.
If a BTS is not installed and the batteries will operate in hot or cold conditions,
manually adjust the temperature settings to suit the conditions. See “Configuring
Battery Characteristics and Battery Charging” on page 3–5.
All networked Xanbus devices share battery temperature information. If there is
more than one BTS used within the system, then the highest reported
temperature will be used for the temperature compensation value of the battery
charge algorithm.
See Figure 2-9 for the location of the solar charge controller BTS port. Single
knockouts on the back and bottom of the solar charge controller are provided for
routing the BTS cable. See Figure 2-4.
To install the BTS:
1. Remove the solar charge controller’s wiring compartment cover.
2. If necessary, remove a single knockout from the back or bottom of the solar
charge controller.
WARNING
BATTERY TEMPERATURE
The Battery Temperature Sensor provides necessary information for
performance and safety.
Always install and connect the Battery Temperature Sensor (BTS). See note
directly below.
Failure to follow these instructions can result in death or serious injury.
Note: For all BTS compatible Xanbus-enabled devices in the system, at least one
BTS must be separately installed for each device type associated with a battery.
If there is a group of the same devices forming a multi-unit setup, only one BTS is
required per device type connected to the same battery (same DC association).
See the installation guide of each device for BTS installation instructions.
Important: If the sensor cable is damaged and the wires are shorted, the solar
charge controller displays an over-temperature fault message. If the BTS wires
have been cut, the solar charge controller assumes that the BTS is not
connected.
Replacement Battery Temperature Sensors are available from Schneider
(replacement part number 808-0232-02).
