Chapter 2 Installation Device Settings
Branch Feeder Monitor 136_Installation Operation and Manual 21
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.
2. When using the expertpower client, submeter address 99 on the Ethernet port COM2 is
reserved for the BFM136 router and must not fall inside the range of the submeter addresses for
this port.
Select your submeters (both metering and totalization) in a sequence without gaps so that your device
does not occupy unnecessary network addresses.
If you connect a number of devices to a serial network, allocate a range of addresses for each device so
that they do not overlap. For example, if you use three devices with 12 submeters in each one, assign the
base address 1 to the first device, the address 13 to the second, and the address 25 to the third device so
that they will occupy three non-overlapped address ranges 1 through12, 13 through 24, and 25 through
36.
2.5.4 Basic Device Settings
For proper device operation, select the correct power frequency (see Basic Meter Setup) and set the
correct primary ratings for device current inputs (see Channel Assignments) before you connect the device
to your network.
2.5.5 Energy/TOU System
The BFM136 provides 4 separate billing energy (total/summary and parallel tariff and maximum demand)
registers for each individual submeter. Each register can be linked to any internal energy source or another
submeter. The first billing register in your meter is linked to the kWh accumulator by default. Other registers
are not operational unless you configure them through the Energy/TOU Setup (see Configuring Billing
Energy and TOU Registers).
