Using the Charger
ENG
9.1.1 I phase (bulk)
The "STATUS" LED constantly lights Red.
In the first stage of the charging process, the depleted battery is charged with a constant
current until the battery voltage reaches I phase setting voltage (13.5V/13.8 V or 27.0V/27.6
V). When the battery reaches this voltage level, the charging current gradually drops. When
the current drops down to 80%, the charger switches over to Uo phase setting voltage
(14.0V/28.0V or 14.4 V/14.8 V or 28.8 V/29.6 V). Typically the battery is charged to 70-80% of
its capacity.
9.1.2 Uo phase (absorption)
The "STATUS" LED constantly lights Orange.
This main charging phase could be set to the maximum of 4/6/8 hours or unlimited, and the
current rises again to its maximum value. The current remains constant as long as the battery
voltage is below Uo phase setting voltage (14.0V/28.0V or 14.4 V/14.8 V or 28.8 V/29.6 V).
After reaching the setting voltage, it remains constant. However, the current drops again. Within
this main charging phase, the battery is charged to 95% of its capacity.
Note The charging voltage and the period for the main charging phase (Uo phase) can be selected using
the switch field S1.
9.1.3 U phase (float)
The "STATUS" LED constantly lights Green. If the current decreases to 10% or under the
rated current or if the time limit of 4/6/8 hours is exceeded, then the charger switches over to
economy charging (13.5V/13.8 V or 27.0V/27.6 V).
Note Batteries may be charged separately from each other if the chargers have double charging or three-
fold charging connections. The outputs are separated internally by diodes, thus the weaker battery will be
always first charged to the charging level of the stronger battery.
Attention
The maximum battery capacity should NOT exceed the specified capacity, otherwise the functi-
ons of the individual charging phases could be influenced.
9.1.4 8-day conditioning
If the battery charger stays at U phase for 8 days, it will switch back to 3-stage charging IUoU,
and stay at Uo phase for 60 minutes to revive the battery.
Note
1. 8-day conditioning will be terminated whenever equalization function or half power mode is activated.
2. When the charger is in the equalization stage or half power mode, 8-day conditioning will NOT be
triggered.
