Installing The Optional Battery Temperature Sensor (Bts) - Xantrex Truecharge TC1012 Installation Manual

Installing the Optional Battery Temperature Sensor
(BTS)
Xantrex strongly recommends that you install the optional
Battery Temperature Sensor (BTS) to protect your battery
and improve charging accuracy. If no BTS is connected, the
charger defaults to the charging temperature settings (Cold,
Warm, or Hot). It is important to set this before the BTS is
installed to ensure that even when the BTS connection is
subsequently lost due to a BTS malfunction or a severed or
loose wire connection, an approximate representation of the
battery temperature is passed on to the charger.
To install a BTS:
1. Switch off all devices operating from the battery.
2. Connect the ring terminal on the sensor directly on to the
3. Route the sensor cable to the charger and plug it to the
Important:
BTS cables should be routed away from the AC mains line and
DC battery cables.
Also, if the BTS is unplugged after a battery overtemperature
fault, the charger will stop charging. Use the onboard display to
set the appropriate temperature setting to restart charging.
CAUTION: Battery damage
In the absence of a BTS, setting a battery temperature that is lower
than the actual temperature will cause the battery to be overcharged
and may damage or reduce the life of the battery or cause a hazard.
Setting the temperature higher than the actual temperature will
result in under-charging the battery.
