Compact Series Backup Batteries
The TC Compact Series contains one non-rechargeable AA (LR6) battery and one
non-rechargeable coin cell (BR2032) battery that serve as a power backup in the event
of a power failure. The batteries only discharge during a power loss. They do not
recharge.
CAUTION
Only use a 3.6 Volt lithium battery in TC Compact models with extended temperature
range operation.
Only use a 1.5 Volt alkaline battery in standard
TC Compact models.
• The 3.6 Volt lithium battery is designed to operate at both high and low temperature
extremes, and it provides a long service life in an extended temperature environment.
• The 1.5 Volt alkaline battery is not guaranteed to provide backup protection in
models with extended temperature range operation, even if the controller is operating
in a room-temperature environment.
• If a 3.6 Volt lithium battery is used in standard TC Compact
models, the battery
quickly discharges and provides much less backup protection than a 1.5 Volt alkaline
battery.
AA Battery
CAUTION
Batteries
Failure to change DEAD alkaline battery will eventually result in battery leakage,
causing permanent damage and loss of building control.
Failure to change a DEAD lithium battery will result in loss of trend and database if
not backed up, causing loss of data or building control.
Establish a preventative maintenance schedule based on expected battery usage and
life cycle.
● The AA battery maintains databases and volatile data, such as Trend, in RAM
when power to the controller is off.
● If reserve power in the AA battery is low, the battery status is reported as LOW or
DEAD and the red LOW BATT LED on the field panel is lit. When this occurs,
replace the battery; do not wait until it goes dead.
● Using PPCL and the $BATT point, the TC Compact can be programmed to signal
an alarm printer and an operator terminal with a battery replacement message.
