4.9.1 Frequency of Measurement
NOTE:
N/A – for BDT only. BDT not available on Sageon II 200A.
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.
4.9.2 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, cell mm, 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
With all the batteries, load and AC cabling wired, and checked for correct polarity, the following steps
commission the system:
•
Ensure no rectifiers are installed in the power module 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 trip to the appropriate voltage (44.0V default).
o
set the Battery Switch to “Normally Open”
o
set the Cct Switch to “Normally Open”
o
set the battery transducer FS as size according to ordered transducers.
o
set the amount of battery temperature compensation voltage adjustment if used and after
confirming that the battery temperature is being measured
o
set the battery charging current limit to 10% of the Ah rating (i.e. if 150Ah battery is
used, set the limit to 15A) – this value can be adjusted later to meet your specific
charging requirements.
In many cases, these values are set up in the factory and will only require modification if the particular
battery is being used requires a different set up.
