Device Settings
Before operating your BFM136, provide the device with information about
your particular environment. The device front display (see
) and the supplementary PAS software (see
) allow you to configure the BFM136 for your particular
use.
Password
The BFM136 configuration setups are secured by a factory-preset password.
Contact your dealer for your primary password. Later, you will be able to
change the password via the device Access Menu (see
Submeter System
The BFM136 provides up to 36 submeters with separate measurement and
energy registers. Each submeter can service current inputs dedicated to a
particular consumer (metering submeter) or be used as a totalization meter
for automatic totalization of energy from different sub-consumers (totalization
submeter). Additionally, the BFM136 provides four more totalization
submeters (37 through 40) that you can use for totalization purposes when
all 36 metering submeters have been utilized.
A submeter remains inactive while there are no current inputs associated
with the submeter (see
), or until you link another
submeter as a source to its energy registers making it a totalization submeter
(see
Setting up Total and Tariff Registers
). The Channel Assignment setup
allows you to link one to three current inputs to each submeter and to specify
the primary rating of the current transformers. A totalization submeter
provides totalization of energy from any number of metering and totalization
submeters.
By default, your device is configured for 12 three-phase metering submeters
with 100A (maximum) current inputs (50A nominal rating).
Submeter Addressing
The BFM136 uses the Modbus communication protocol for data transmission
and accessing setups through communications. A full description of the
communications protocol is found in the BFM136 Modbus Reference Guide
provided with your device.
Each active submeter in the BFM136 is assigned a unique communication
address that allows accessing its private registers and setups. All submeter
addresses are assigned automatically in a sequential order starting with the
device base address that is programmed through the device Communication
Setup (see
Setting Up Communication Ports
). The following table illustrates
submeter addressing in the device with the base address N.

Your device is factory preset to address 1 and occupies the range of
addresses 1 through 12, configured for 12 three-phase submeters.
NOTES
1. Device setup settings, excluding the alarm setpoints and data log setup,
are shared across all submeters. Though you can read or write them
using any submeter address, your changes affect all submeters in the
device.
