12-24V
AUTOMATIC DIAGNOSTIC CHARGER FOR 12V LEAD-ACID BATTERIES FROM 3Ah TO
400Ah or 24V LEAD-ACID BATTERIES UP TO 200Ah
DO NOT USE FOR NiCd, NiMH, Li-Ion OR NON-RECHARGEABLE BATTERIES.
IMPORTANT: READ THE FOLLOWING INSTRUCTIONS BEFORE USING THE CHARGER
This appliance can be used by children aged from 8 years and above and persons with reduced
physical,sensory or mental capabilities or lack of experience and knowledge if they have been given
supervision or instruction concerning use of the appliance in a safe way and understand the hazards
involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made
by children without supervision.
SAFETY WARNING AND NOTES:
Batteries emit EXPLOSIVE GASES - prevent flame or sparks near batteries.
Disconnect
AC power supply before making or breaking DC/battery connections. Battery acid is highly corrosive. Wear protective clothing and
eyewear and avoid contact. In case of accidental contact, wash immediately with soap and water. Check that the battery posts are
not loose; if so, have the battery professionally assessed. If the battery posts are corroded, clean with a copper wire brush; if greasy
or dirty, clean with a rag dampened in detergent.
Use the charger only if the input and output leads and
connectors are in good, undamaged condition. If the input cable is damaged, it is essential to have it
replaced without delay by the manufacturer, his authorised service agent or a qualified workshop, to
avoid danger.
Protect your charger from acid and acid fumes and from damp and humid conditions both during use and in
storage. Damage resulting from corrosion, oxidation or internal electrical short-circuiting is not covered by warranty. Distance the
charger from the battery during charging to avoid contamination by or exposure to acid or acidic vapours. If using it in the horizontal
orientation, place the charger on a hard, flat surface, but NOT on plastic, textile or leather. Use the fixing holes provided in the
enclosure base to attach the charger to any convenient, sound vertical surface.
EXPOSURE TO LIQUIDS:
This charger is designed to withstand exposure to liquids accidentally spilled or splashed onto the
casing from above, or to light rainfall. Prolonged exposure to falling rain is inadvisable and longer service life will be obtained by
minimizing such exposure. Failure of the charger due to oxidation resulting from the eventual penetration of liquid into the electronic
components, connectors or plugs, is not covered by warranty.
CONNECTING THE CHARGER TO THE BATTERY
1.
Disconnect AC power supply before making or breaking DC / battery connections.
2.
If charging a battery in the vehicle or craft with the battery clips, before making connections, first check that the battery clips
can be safely and securely positioned clear from surrounding wiring, metal tubing or the chassis. Make connections in the
following order:
First connect to the battery terminal not connected to the chassis (normally positive), then
connect the other battery clip (normally negative) to the chassis well away from the battery and
fuel line. Always disconnect in reverse sequence.
3.
When charging a battery out of the vehicle or craft with the battery clips, place it in a well ventilated area. Connect the charger
to the battery: RED clamp to POSITIVE (POS, P or +) terminal and BLACK clamp to NEGATIVE (NEG, N or –) terminal. Make sure
the connections are firm and secure. Good contact is important.
4. If the battery is deeply discharged (and possibly sulphated), remove from the vehicle or craft and inspect the battery
before connecting the charger for a recovery attempt.
Visually check the battery for mechanical defects such as a bulging
or cracked casing, or signs of electrolyte leakage. If the battery has filler caps and the plates within the cells can be seen from
the outside, examine the battery carefully to try to determine if any cells seem different to the others (for example, with white
matter between the plates, plates touching). If mechanical defects are apparent do not attempt to charge the battery, have the
battery professionally assessed.
5.
If the battery is new
, before connecting the charger read the battery manufacturer’s safety and operational instructions
carefully. If applicable, carefully and exactly follow acid filling instructions.
PROCEEDING TO CHARGE
CHARGING TIME
Charge time on a flat but otherwise undamaged battery
:
a 100Ah 12V / 50Ah 24V battery should take no more than about 24
hours
to progress to the self-discharge check.
Deep-discharged batteries may take significantly longer, a full charge may not be achieved within the 72 hour charge safety limit.
°t
: The charge voltage is inversely regulated according to ambient temperature i.e. voltage is increased at lower temperature,
decreased at higher temperature. Adjustment: -0.004V / cell / °C above or below 20°C (68°F).
If voltage selection in STEP 1 matches the expected battery voltage and there are no connection errors as
described in STEP 2, then fully automatic operation starts from STEP 3.
