Indication & Configuration

BMS100 Series - Component Functions

Module Indicators

The module provides two visual indicators, allowing for quick visual identification of status and faults without the need for additional tools or adapters.

YELLOW Indicator State	Module Status
OFF	NO POWER/MODULE FAULT
SOLID	POWERED/STANDBY
FLASHING	SHUNT(S) ACTIVE

RED Indicator State	Fault
OFF	NO FAULT
SOLID	BATTERY FAULT
FLASHING	COMMUNICATION (CAN) FAULT

Module Addressing Scheme

The modules provide an eight (8) position rotary switch to set the internal CAN address.

Each rotary increment (0 to 7) increases the module_address of 300 by a factor of 10.

For example, a module with the rotary switch at 12 o'clock (position 0) would have a module_address of 300:

module_address = 300 + 0 * 10 = 300

A module with the rotary switch at 9 o'clock (position 6) would have a module_address of 360:

module_address = 300 + 6 * 10 = 360

Changing Address

If the module is powered, and the rotary switch position is changed the module will enter failsafe (YELLOW indicator off, RED indicator solid).

This is implemented to ensure undetected dynamic CAN address changes during operation do not occur.

To change address when the module is powered, adjust the rotary switch position, then press & release the reset button.

Temperature Sensor Configuration

The modules contain an internal lookup table suitable for 10K B25/85 3435K NTC thermistors, supporting a temperature range between -40C and 160C.

CAETRON can offer custom lookup tables for other suitable temperature sensors if required.
