CONNECTION AND BATTERY CHARGING:
The EDT-150-5191 charger has defined charging modes:
-Constant voltage charging (or fast charging).
-Flotation.
During constant voltage (or fast charge) charging mode, the charger sets a charge voltage
higher than the float voltage (output 1 of the charger). The main features of this mode are:
-
The charge current is limited to a maximum (unlimited) value.
-
Voltage compensation with temperature (hab_comp) can be enabled/disabled.
When the battery current remains below a certain value in a stable manner, the charger
switches to float charging mode. It is also possible to switch to this mode when a maximum
time under charge at constant voltage is exceeded. This state is characterised by:
-
The charge current is limited to a maximum (unlimited) value.
-
In this charging mode, the output voltage is always compensated with the battery
temperature (comp_flot).
The charge changeover from float mode to constant voltage mode is not provided for unless:
-
An AC failure occurs and subsequently a correct AC reappears.
-
If the equipment has disconnected the rectifier for a certain period of time and
then reconnects it, for example, when performing a battery test.
In addition to the charging modes, the equipment considers the following situations:
-
The minimum battery voltage to start the charging process is 4V (battery
detection). The charger will try to recover it at full current, ensuring that the output
voltage is always within the specified range.
-
The indicator lights on the equipment allow you to see which charging mode the
charger is in at all times.
-
The battery charging current is always limited, regardless of the charging mode.
-
Each time AC power is applied to the equipment after a mains failure or
disconnection, it:
o
Starts battery charging
o
The charging process starts in constant voltage mode. Subsequently, it will
be floated if the conditions are met.
-
On the other hand, to replace one battery with another (usually a new one) it is
not necessary:
o
To stop powering the charges.
o
To turn off the equipment.
o
To perform any special operation on the equipment.
Simply replace the batteries with equivalent ones following the battery
replacement procedure indicated in this operation manual.
If the battery model is changed, the configuration of the equipment must be
revised.
