Battery Charger Description; Technical Data - Deca SM 1236 Manual De Instrucciones

< Carefully read the recharging instructions provided by the
Manufacturer for maintenance -free batteries.
< Never open the electrolyte caps in maintenance-free
batteries.
< Some maintenance-free batteries have level indicators.
Whenever the acid level is indicated as being too low, the
battery must be replaced. Never attempt to recharge such
batteries.
< Never charge frozen batteries that might explode.
< Never attempt to charge batteries that cannot be recharged
or other types than those indicated.
< Always wear safety goggles closed at the sides, acid-proof
safety gloves, and acid-proof clothing.
< Never position your face close to the battery.
< Position the battery charger as far as possible from the
battery
< Never let acid drip onto the battery charger, cables or
clamps.
Additional warnings
< Never position the battery charger on flammable surfaces.
< Never place the battery charger and its cables in the water
or on wet surfaces.
< Position the battery charger with adequate ventilation; never
cover it with other objects or close it inside containers or closed
shelves.
Warnings for batteries in vehicles
< Maintain a safe distance from all moving parts, such as fans,
transmission belts and pulleys.
< Maintain a safe distance from all heated surfaces such as
engines and cooling systems to avoid burns.

Battery charger description

4 Make sure that the voltage of the battery corresponds to the
battery charger's charging voltage.
4 Make sure that the plug is not plugged into the socket.
30 Volt 50/60 Hz
3,6 Amp Max
1 Volt
IUoUp with 3 automatic
switching phases
4 Connect the red clamp (+) to the battery's positive pole and
the black clamp (-) to the battery's negative pole.
i
The "B" LED lights up whenever the clamps have been
connected to the battery with reverse polarity. Invert the
connection.
i The "E" LED lights up to indicate that correct connection
has been made to the battery and that the battery charger is
in "Stand By" position (awaiting the selection of the charging
program P).
4 Use the MODE key to select the charging program desired
for the battery.
4 Plug the plug into the socket to begin charging.
4 In order to interrupt charging, first unplug the plug from the
socket and then disconnect the clamps from the battery.
i If, after selecting a charging program, the "C" or "D" LED
fails to light up, this means that no voltage is reaching the
battery charger: check the power supply connection
Warnings for batteries in vehicles
< Never connect both battery charger clamps directly to the
poles of the battery. Always connect the first clamp to the
battery and the second clamp to a thick part of the body or
the engine far from the battery, fuel tank cap and fuel line.
In this way, the generation of a spark will not create danger.
Connect the battery charger to the power supply only after
performing the operation above.
< In order to interrupt charging, disconnect the following in
the order below: the plug from the power supply socket, the
clamp connected to the vehicle's body, and then the clamp
connected directly to the battery .
Charging program selection
Any of the following charging programs can be selected:
P1) 14.4 Volt – 0.8 Amp charging
Suited for batteries with capacity in the range of 1. - 35Ah:
e.g. motorcycles.
P2) 14.4 Volt – 3.6 Amp charging
Suited for batteries with capacity in the range of 35 - 10Ah:
e.g. cars.
P3) 14.7 Volt – 3.6 Amp charging
Suited for batteries with capacity in the range of 35 - 10Ah:
e.g. cars.
Some battery producers suggest using this program for batteries
that run at temperatures of less than 5°C.
Charging follows an IUoUp cycle with 3 phases with automatic
switching. Fig. 2
PHASE 1
Charging is performed with the maximum current set until the
voltage of the battery is raised above 14.4V or 14.7V depending
on the charging program ("C" LED lit up). In this phase, the
battery is brought to around 80% of its charge
PHASE 2
Charging with constant voltage until the current delivered reaches
a value of 0.4A ("C" LED lit up).
Whenever charging lasts longer than 18 hours, the battery
charger shifts to the next phase in order to avoid damaging
defective batteries.
PHASE 3
End of charging and shift to battery charge level checking
process ("D" LED lit up). After the battery has been charged,
the battery charger checks the battery's voltage, and whenever
voltage falls below 1.8V (for charging programs P1 and P2)
