remote workstation running the SageView software. For more information on SageView operation, refer to
TG990-4262-00 on the documentation CD. Additionally, remote monitoring of the Sageon Shield Standalone
Battery Monitor can be accomplished via SNMP. Refer to the SageNET setup and configuration guide on the
documentation CD for more information.

CELL MONITORING BOARD
The Sageon Battery Monitor (SBM) PCB is located under the sheet metal cover of the Battery Distribution
Module (BDM). It is used to monitor individual cells of a battery during float or equalization operation, or during
a discharge. Each SBM unit is capable of monitoring up to 24 cells or monoblocks. An additional three external
SBM units (up to four SBM units total) can be used to monitor up to four battery strings of 24 cells or
monoblocks each.
The cell voltages can be viewed in real time when the SCU is connected to a PC. The SageView software that is
running on the PC can display the cell voltage data in various convenient formats to ascertain the state of health of
batteries. In addition to the real time representation of the data on the SageView, the cell voltages can also be
observed in real time on the SCU display locally.
A number of pre-programmed parameter levels are used to generate alarms that are annunciated on the SCU front
panel by a LED and screen message and remotely via voltage free contacts, or via the USB port, which can
connect directly to a PC locally, or remotely via SNMP and an Ethernet connection.

MAIN FEATURES OF THE SBM BOARD
•
Up to 24 cells can be monitored by a single SBM module. Cell voltage setting can be 2V, 4V, 6V,
and 12V.
•
Up to four SBM boards can be connected to a single SCU.
•
Individual cell voltages of a battery can be viewed on the SCU display in real time. The cell voltage
rounded to the nearest 5mV (applies only to 2V range) is displayed together with the cell number and
its percentage deviation from the average cell voltage of the battery.
•
All the cell voltages can be displayed in a “Histogram” format locally or remotely on a PC using
Sageview software for a very convenient and rapid visual indication of normal and deviant cells.
•
As the SBM is permanently connected to the batteries, daily or weekly viewing of the steady state cell
voltages for the different batteries in a system to a remote monitoring PC can be very useful for
anticipating the state of health of the batteries.
