declining ba tt ery voltage. At a certain ba tt ery voltage level, the charger jumps back to the
Bulk stage and will fi nalize a complete charging process again, once the ba tt ery load
consump ti on has dropped below the charger's maximum output current level.
The fourth stage called “Pulse”, will perform a short refresh charge of approximately 1 hour
each 7 days while the charger operates in the Float stage. This will keep the ba tt ery in
op tim al condi ti on while prolonging it's life ti me. The ba tt ery can remain connected to the
ac tiva ted charger con ti nuously, without risk of overcharging.
When the standard selectable charging programs do not sa ti sfy your requirements, or
when di ff erent voltage- and current levels are needed, you can edit or create your own
charge programs using SAMLEX Dashboard. Up to 8 di ff erent stages can be linked together
and all individual stages can be con fig ured extensively.
5.2 Equalizing a fl ooded ba tte ry
If you are using a flo oded lead acid ba tt ery, an occasional equaliza ti on charge cycle may
be recommended by the manufacturer. This might also be true when the fl ooded ba tt ery
has been very deeply discharged or o ft en charged inadequately. During equaliza ti on, the
ba tt ery will be charged up to 15.5V (or 31V for 24V models) at a reduced output current
level. Before star ti ng an equaliza ti on charge cycle, the following cau ti on statements must
be read carefully :
When th e battery temperature sensor is installed, the charger automatically compensates
the charge voltages against battery temperature (except when set to Lithium). This means
that the charge voltages are slightly increased at lower temperatures and decreased at
higher temperatures (-30mV/°C at 12V chargers and -60mV/°C at 24V chargers). This way,
overcharging is prevented which prolongs your battery’s lifetime.
!
CAUTION
Equaliza ti on should only be performed on a flooded (wet) lead acid battery. Therefore the
Powersine Combi only allows equalization when the battery type DIP switches are set to
Flooded. Other battery types like GEL, AGM or Lithium will be damaged by this process.
Always follow the battery manufacturer ' s instructions when equalizing flooded batteries.
During equalization, the battery generates explosive gasses. Follow all the battery safety
precautions enclosed with your Powersine Combi. Ventilate the area around the battery
sufficiently and ensure that there are no sources of flames or sparks in the vicinity.
Disconnect all loads connected to the battery during equalization. The voltage applied to
the battery during this process may be above safe levels for some loads.
The Powersine Combi cannot automatically determine when to stop the equalization of a
battery. The user must monitor the battery ' s specific gravity throughout this process to
determine the end of the equalization cycle. The internal 2 hours time-out timer of your
charger is only intended as a safety feature, but may not be sufficiently short to prevent
