9.3.4 Configure the Battery Parameters
The system is only permitted to have a single battery group.
ATTENTION
:
If the system does not have batteries connected, the battery string must be deleted. This is
important to have the system mode reported correctly. Go to System > Inventory > Battery , and then
remove the battery string.
If a battery is required, configure it as follows:
1. Go to
System > FXM System > Inventory > Battery
. On the Batteries table, you will see a list
with one battery.
2. Click the more details icon on the right-side of the table.
3. Click the edit icon on the right-side of the
Battery Configuration
table.
4. In the Configuration table assign the battery a name and description if required.
5. Select the
Battery Voltage Source
. This is the battery voltage reading from the FXM ADIO
module.
6. Select the Battery Current Source . This is the battery current reading from the FXM ADIO
module.
7. Configure the battery temperature values. See the following section for instructions on how to do
this.
8. Configure the battery capacity. This value is usually available from the battery specification sheet.
Use the capacity at the 20-hour rate (C/20).
9. Configure the open circuit voltage. This value is sometimes available from the battery specifica -
tion sheet. If it is not, leave it at the default value.
10. Use the wizard to configure the Peukert exponent. This value usually available from the battery
specification sheet.
If the Peukert exponent
(n)
is not supplied in the battery specification, calculate it by the equation:
where
T
is the discharge time in hours and
I
is the corresponding discharge current in amps. Both
T
and
I
are often available in the battery specification sheet.
11. In the
Alarms
table, configure the alarms.
9.3.5 Configure the Battery Temperature Sensors
The battery can have any number of battery temperature sensors. Depending on your requirements you
can choose to have only a single temperature reading for your battery, or one for each battery block, or
one for each battery cell.
