STATUS
Bulk
•
Bulk Charging – The battery charger is delivering maximum current
(determined by the Charge Rat e setting) to the batteries. The charger
remains in Bulk Charge until the absorb voltage (determined by the Bat t ery
Type setting) is reached.
CHARGER
Chg Stby
Charger Standby – The charger is disabled to prevent any charging, but the
AC power to the AC input is still available on the AC output.
Info: Press the CHANGE button to turn the charger on. See Section
3.3.10 for more information on Charger Standby.
STATUS
Charging
•
Charging – Once Charge mode has been enabled, the unit waits and
displays "Charging" to determine the charge routine. If the battery voltage
is low (≤12.8 VDC/12-volt models, ≤25.6 VDC/24-volt models, or ≤51.2
VDC/48-volt models), the charger initiates Bulk Charging. If the DC voltage
is higher than this voltage, the charger skips the Bulk and Absorb Charging
stages and goes directly to Float Charging.
Info: If the LFP battery type has been selected, the charger will go
into the Bulk charge mode each time AC is connected—regardless
of the battery voltage. However, if AC is reconnected less than two
minutes after being disconnected, the charger will return to the
previous charge mode.
