7.2.4.1. Ah configuration of parameter ‘12’.
•
Standard models are configured with factory default settings, so
it is not necessary to perform any actions to adjust this parameter.
For extended backup models, however, it is necessary to adjust
the value to the total capacity of the battery pack. Any altera-
tion of the battery pack will entail a readjustment, so it will be
necessary to adapt the value in the event of future expansions.
•
There are basically two reasons to perform the adjustment
without it affecting the correct functioning of the device if it is
not done, although it is more than recommended:
a.
The charging current of the batteries is directly related to
the capacity of the battery pack.
The charger will adapt the charging factor automatically ac-
cording to the value of the total capacity entered, up to the
maximum of the current that is possible.
This results in faster charging and therefore greater
availability and more immediate backup in the event of
frequent mains failures.
b.
Entering the value in Ah is vital for the control to be able to
calculate and show the backup available on the LCD display,
without further alterations.
The settings values are determined as follows:
1.
Devices with backup extension.
They are configured by a standard model plus the battery module
or modules. The capacity of the batteries of both is indicated in
the following Tab. 8 and 9.
Example for an SLC 2000 TWIN RT2 A and backup extension
module 698BU000003:
9 Ah + 18 Ah = 27 Ah (value for parameter 12).

2.
B1 equipment.
B1 models do not have batteries in the same box, so a battery
module or well the user will have them.
Example for an SLC 2000 TWIN PRO2 A B1 and three modules of
extension of autonomy 698BY000002:
(3 x 18 Ah)
= 54 Ah (value for parameter 12).
