CR2032, Lithium Coin Cell, 3V, 225mAh
Terminal Descriptions
PFRN Connection
The PFRN connection must connect to a BMS UI port either directly, or through a Network or Modbus card.
USB Port
The datalogging USB port is used for downloading event log information and firmware updates. Please refer to
PROFIRE’s Firmware Update Guide (http://3100.profireenergy.com/pf3100-documentation/) for detailed
instructions on performing a firmware update. The USB should not be inserted or removed unless the area is
known to be non-hazardous, as removing or inserting the USB may cause a spark.
Reset Button
The Reset button will reset the internal processor. This can be used if the application freezes during operation.
Battery
The UI uses a battery that provides power to the clock on the user interface. The battery (usually a Panasonic
CR 2032 3V non-rechargeable battery, or other electrically compatible battery) should only be changed if the UI
is powered down. The battery should not be inserted or removed unless the area is known to be non-hazardous,
as removing the battery may cause a spark. The battery should not need to be changed for approximately 5
years.
