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.
Only one BTS is required if multiple XW SCCs or a complete XW Power System
with XW Inverter/Chargers are networked together using Xanbus. All networked
XW Series devices share battery temperature information, and the BTS can be
connected to a XW SCC or an XW Inverter/Charger.
See Figure 2-8 on page 2–10 for the location of the XW SCC BTS port.
Single knockouts on the back and bottom of the XW SCC are provided for routing
the BTS cable. See Figure 2-4 on page 2–6.
To install the BTS:
1. Remove the XW SCC wiring compartment cover.
2. If necessary, remove a single knockout from the back or bottom of the XW
SCC.
3. Connect the ring terminal on the BTS directly to the negative 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. See Figure 2-14.
If using the adhesive backing, install the BTS 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.
Important:
If the sensor cable is damaged and the wires are shorted, the XW SCC
displays an over-temperature fault message. If the BTS wires have been cut, the XW SCC
assumes that the BTS is not connected.
Replacement Battery Temperature Sensors are available from Xantrex (replacement part
number 808-0232-02).
