CTEK ZAFIR 100 - Manual (Page 4)

3. The lamp for deeply Discharged battery (1) will indicate if the battery voltage is low. If lamp
1 blinks, this indicates that the battery is lightly sulphated. Read more under ”CHARGING
PHASES”
4. Normal charging is indicated by the following lamps: deeply Discharged (1), Bulk Charge
(2), Absorption Charge (3) or Maintenance Charging (4). When the maintenance lamp is lit,
the battery is fully charged. The charge will restart if the voltage drops. The charger can be
connected for months.
SUPPLY or RECOND are indicated when the lamps for these settings are lit (5 or 6).
5. If the battery cables are connected incorrectly, the reverse polarity protection will make sure
that neither the charger nor the battery are damaged. In this case, the red warning lamp (0) will
be lit.
6. If nothing happens. If the setting lamp is lit but no other light comes on, the connection to
the battery or to the chassis may be poor, or the battery may be faulty. Start by improving the
contact between the battery and the charger.
7. Charging can be interrupted at any time by disconnecting the power cord from the wall socket
or by putting the charger in "POWER-ON" mode (lamp A). Always disconnect the power cord
from the socket before removing the battery cables. When you interrupt charging of a battery
mounted in a vehicle, always disconnect the battery cable from the chassis before removing the
other battery cables.
CHARGING PHASES
Mode chosen: ”NORMAL” or ”SNOWFLAKE”
ZAFIR 100 is a multi stage fully automatic charger. Lamp B for chosen setting ”NORMAL” and
lamp C for chosen setting ”SNOWFLAKE”.
Desulphation (Lamp 1, flashing)
Desulphation with pulsing for sulphated batteries. Indicated by flashing lamp 1.
Start (Lamp 1)
Starting phase for charging. The starting phase continues until the battery’s terminal voltage
has risen over a preset level. At this point, charging goes into the bulk phase. If the terminal
voltage has not reached the preset level within 8 hours, charging is suspended. The error mode
is indicated. This indicates a battery which is faulty or has too large capacity. If a large battery
is charged that has been severely discharged, it may be necessary to restart the charger after 8
hours. Start is indicated by lamp 1.
Bulk (Lamp 2)
Primary charging where approximately 80% of the charging happens. The charger delivers
maximum current until the terminal voltage has risen to the preset level. After a number of
hours, the charger goes on to the next phase, even if maximum voltage is not reached. Bulk is
indicated by lamp 2.
Absorption (Lamp 3)
Final charging, voltage is kept at the preset level. During this phase, the current is gradually
reduced. If the maximum length of time for Absorption is exceeded, the charger automatically
continues with Analysis. Absorption is indicated by lamp 3.
Analysis (Lamp 3)
Charging is suspended for a short period and the battery voltage measured. If it falls too
quickly, the battery is probably faulty. Charging is suspended and an error is indicated (lamp 0).
Maintenance charging - float (Lamp 4)
During the first 10 days of maintenance charging the battery is maintained with constant volt-
age, 13.6V. Float-maintenance is indicated by lamp 4.
