4.4
MoDe 2 DescriPtion (14.4V/8.0a)
4.4.1 This mode is mainly for charging large batteries with a
capacity over 160Ah in normal conditions. Press the
MODE button until the LED adjacent to the car symbol
is illuminated. Charging will automatically begin with a
current of 3.8A ± 10% and the ‘charging’ LED will
illuminate. This LED will remain on throughout
the entire charging process until the battery is fully
charged up to 14.4V ± 0.25V. At this stage the
‘charging’ LED will extinguish and the ‘fully charged’
LED will illuminate. The trickle charge current now
becomes available for battery maintenance.
4.5
MoDe 3 DescriPtion (14.7/8.0a)
4.5.1 This mode is mainly for charging large batteries with
a capacity over 14Ah in cold conditions or for charging
several AGM batteries with a capacity over 20Ah.
Press the MODE button until the LED adjacent to the
ice crystal symbol is illuminated. Charging will
automatically start with a set delay with a current of
3.8A ± 10% and the ‘charging’ LED will illuminate. This
LED will remain throughout the entire charging process
until the battery is fully charged; up to 14.7V ± 0.25V. At
this stage the ‘charging’ LED will extinguish and the
‘fully charged’ LED will illuminate. The trickle charge
current now becomes available for battery
maintenance.
4.6
MoDe 4 DescriPtion (cal)
4.6.1 This mode is for lead calcium or a battery below 10.5
volts with no capacity to absorb charging current, the
charger will automatically raise the output voltage
up to 17 volts. The Mode 4 LED will illuminate and
flash, the charging LED will illuminate. If the battery
cannot be recovered within 2 hours the “Fault”
(!) LED
will illuminate. The battery may require replacing.
4.7
MoDe 5 DescriPtion(13.5v 5amp output)
4.7.1
A DC power supply for use with 12 volt appliances
fitted with a vehicle accessory plug. Maximum output
power is 80 watts.
4.8
fauLt Protection (!)
4.8.1 In the case of a short circuit, open circuit, or reversed
polarity, the charger will turn off the electronic system
and revert to standby mode. Additionally the “Fault”
(!)
LED will illuminate. The fault must be identified and
resolved before any of the charging modes are
initiated.
4.9
oVerHeatinG Protection
4.9.1 If the charger becomes too hot during the charging
process or due to extreme ambient temperatures the
power output is automatically reduced to a trickle
charge to protect the unit. Once the temperature drops
the charger will increase the power output automatically.
5.1 The SMC04 charger has a nine step fully automatic
charging cycle as shown in Fig.3 above, which is
indicative of the typical charging curve for a battery.
5.2 PHase 1 through 5 DiaGnosis & recoVery:
As soon as one of the charging modes is selected the
diagnostic function automatically detects the condition
of the battery i.e. voltage. If the voltage of a deeply
discharged battery is over 7.5V ± 0.5V the charger begins
to pulse charge with a small current to recover it. Pulse
charging ceases when the voltage reaches 10.5V ±
0.5V. If the voltage detected is over 10.5V ± 0.5V the
charger skips pulse charging and switches to the
preselected charging mode.
5.3 PHase 6 BuLK: Up to 80% of the charge is delivered
in this phase.
5.4 PHase 7 aBsorPtion: A constant low charging
current raises the voltage from 14.1V to 14.4V over a
period of time without gassing the battery. In this phase
complete charging up to almost 100% is achieved.
When full charge is reached the charger switches to
phase 8 and 9.
5.5 PHase 8 & 9 Maintenance cHarGe: If the battery
is loaded and/or the voltage across the terminals drops
below 12.8V, the charger starts a maintenance
charging pulse at a constant 0.8A until the voltage
reaches 14.4V at which point the maintenance charge
is turned off. The charger continues to monitor the
battery condition and will cycle between trickle charge
and maintenance charge indefinitely to keep the
battery in peak condition. The charger can be left
connected to the battery in order to perform this
maintenance function.
