FUSES : The charger is electronically protected against short-circuited output and inverted connections,and sparks due

to making/breaking battery connections or accidental short-circuiting, are suppressed though not necessarily totally

absent.In addition the charger is protected by several fuses,located both externally and internally. A fuse at the AC input

protects against mains input disturbances. To replace this fuse,use a suitable coin or screwdriver to twist open the fuse

cover. An internal fuse protects against possible cooling fan malfunction.A thermal fuse acts as final protection against

transformer burn-out.Do not attempt to replace internal fuses,send the charger to an authorised service agent.The fuse

in the in-line fuse holder of the eyelets connection set protects against battery damage or possible explosion in case of

accidental dead-shorting across the eyelets set cabling. Should this fuse blow, check carefully for damage to the

connection set's cables,terminals and connector and replace if damaged or dubious.

Replace any burnt fuse only with a new fuse of identical type and rating.

selection

Models without 12/24V selection switch have no 24V LED.

1) For chargers with 12V/24V selectable output first make sure whether the battery to be charged is a 12V battery (6 cells) or

a 24V battery (12 cells or 2 x 12V batteries connected in series) and place the small charging output voltage selection switch

in the correct position,refer to the above panel.It is essential to do this before making any battery or AC mains connections.

Consult a specialist if unsure.

2) Distance the charger from the battery as far as reasonably possible to avoid any possible acid vapour damage to the

charger. Connect the charger to the battery - RED clamp to POSITIVE (POS, P, +) terminal and BLACK clamp to NEGATIVE

(NEG,N,-) terminal.

3) Connect the charger to a mains supply socket providing AC supply of 220 to 240V. The «POWER ON» LED (this LED

serves also as the charging output voltage selection for the 12V/24V model) should illuminate. If not,check your AC

supply connections.

4) Once all connections are correct, the yellow «BULK» charging LED should light,even if only briefly, together with the

«POWER ON» LED.When the battery is close to being fully charged, the green ABSORB LED will light.A battery already

fully charged or badly sulphated or damaged when connected will cause the green «MAINTAIN» LED to light immediately

when the charger is activated.

NOTE : If the battery connections are inverted,or if the initial battery voltage is below 2V for a 12V battery or below 4V for

a 24V (or 2 x 12V series connected) battery, charging will not start and only the «POWER ON» LED will light.Otherwise,for

as long as the charger is connected to AC supply and battery, the status and condition will be indicated by a LED as per

panel above.

5) The charger will automatically charge, then maintain the battery very close to fully charged unless the battery is

defective.During the BULK CHARGING cycle («BULK» LED) the battery is charged at the maximum constant current out-

put until the monitored voltage rises to 14.4V (at 20°C) for 12V charging,or 28.8V for 24 Volts.The «ABSORB» LED now

lights and charging then changes automatically to 'float' mode, with the voltage limited at 14.4V (12V charging), or

28.8V (24V), so that the continuously monitored current will gradually reduce.When the current falls to a sixth of the

rated charging current, the charging voltage is then limited to 13.7V (at 20°C) for 12V charging, (27.4V for 24V) and

the «MAINTAIN» LED will indicate the battery is ready for use. For as long as the charger remains connected it will

continue to maintain the battery with a charge voltage limited at 13.7V (27.4V for 24V), thus allowing the battery to

draw a small current to compensate for any slight discharge, whether self-discharge or due to any alarm system or

other current loss in the vehicle or other circuit.

6) Should any factor place a load on the battery such that the battery's need for charging exceeds a sixth of the rated

current, the circuit will automatically revert to the «ABSORB» cycle. The maximum constant current will be applied if

the battery voltage reduces below the constant voltage parameters set for the «ABSORB» cycle.The charging program

will again proceed to the «MAINTAIN» cycle once the current reduces below a sixth of the maximum current.
