The alarm log can only be cleared from the front panel. There are no means to clear the
alarm log entries remotely.
4.9 SAGEON BATTERY MONITOR SETUP
With the SBM option enabled, SBM parameters must be set before monitoring can be performed. From the HOME screen, scroll
through the operator display screens shown in Section 4.5.2 to the Auxiliary, “Bat Config” and “SBM Batteries” screens and there
declare the number of battery cells per battery string (2-24) and the number of battery strings (1-4) whose cell voltages are to be
monitored by the SCU.
Refer to the Sageon Battery Monitor Manual (PM990-4209–00) for detailed information.
The quantity of SBM boards needed for the above selection is calculated by the SCU based on battery type and configuration. The
relationship between battery configuration and quantity of SBM boards is shown in the table below.

Frequency of Measurement
The frequency of cell voltage polling is programmable from 10 minutes to 8 hours in 1-minute steps. A typical polling interval is 4
minutes, which yields 15 points for a 1-hour discharge. For a programmed test discharge of 30 minutes, a polling interval of 2 minutes
might be used. This parameter is not accessible from the operator panel. A PC running SageView is needed.
Battery Cell Measurements
When SBM is active, individual cell voltages can be monitored on the operator panel by selecting a battery from the BATT menu and
pressing ENTER. The cell information will appear on the screen and the next and previous cells can be selected by pressing the “up
arrow” and “down arrow” buttons.
Select battery: Battery 1 screen appears after pressing the BATT button. Press ENTER.
Battery cell parameter: Battery 1, Cell 01 values are displayed. As shown here, the cell
voltage is 2.225V, which is a deviation of +12% from the average cell voltage in this
battery string.
Battery cell voltage deviation: Battery 1, Cellmm, cell voltage n.nnnV is dev/-
pp% from the average cell voltage in this battery string. Press “up arrow” or “down
arrow” to change the cell number.
4.10 COMMISSIONING THE CONTROLLER
With all the batteries, load and AC cabling wired, and checked for correct polarity, the system is commissioned by the following steps:
•
Ensure no rectifiers are installed in the Power plant and no load is applied.
•
Plug in the Controller – it should power up off the battery. If not, it is possible that the battery polarity is reversed.
•
Set up the Controller menu items for:
o
number of batteries and size (Ah),
o
number of rectifiers,
o
set the required float and equalize voltages,
o
set LVLD option to ON and set the LVLD Aux to 42.0V
o
set the Battery Switch to “Normally Open”
