OPERATING INSTRUCTIONS
IMPORTANT : Read completely before use.
IMPORTANT ! If the charger has a charging output selector switch to select for 12V batteries (which have 6 cells) or 24V batteries (which have 12 cells), IT IS ESSENTIAL TO ENSURE THAT THE SELECTOR SWITCH IS CORRECTLY POSITIONED ACCORDING TO THE VOLTAGE OF THE BATTERY TO BE CHARGED BEFORE THE CHARGER IS CONNECTED TO IT. If not sure, contact the battery supplier for advice before connecting the charger.
WARNING! Connecting a battery without ensuring that the charging output selection is appropriate to the nominal battery voltage may cause a hazard resulting in the production & accumulation of dangerous explosive gases as well as the overheating and potential destruction or even the explosion of the battery. THIS COULD RESULT IN SERIOUS PERSONAL INJURY OR EVEN DEATH.
CARE : Protect your charger & it’s leads,connectors,fuse holders,fuses & terminations from contamination by acids and fluids, from exposure to damp and humidity, and from physical and accidental damage. Any damage to the unit, its leads or accessory parts resulting from such contamination, exposure or damage is NOT covered by warranty,both during use and in storage.
CONNECTIONS: An additional fused cordset is supplied with eyelets for direct connection to battery terminals and a polarized push connector for connection to battery charger.Consult a professional service agent to permanently connect the cordset to the battery in the vehicle.Ensure that it is positioned and restrained in such a way that it does not impede operation of any moving part of the vehicle and will not cause any danger of electrical short circuit during the normal use of the vehicle.Protect the polarized connector from ingress of grime and dirt.Before connecting the polarized connector to the battery charger,ensure that : ❶ the vehicle is stationary and not operational; ❷ all accessories in the vehicle are switched off; ❸ the polarized connector is completely dry and free of grime and dirt, and ❹ the battery charger is not connected to AC mains power. battery in case of an accidental Should the fuse for any reason blow,have the cordset carefully checked and replace if necessary.Replace a blown fuse only with a fuse of identical rating and type. If intending to charge using the battery clips,first disconnect and remove the battery from the vehicle and place in a well­ventilated area.Ensure that the polarised 2-pin connector is situated away from the battery. Prevent ingress of grime and dirt to the 2-pin connector. If in any doubt concerning any of the above instructions, consult a professional service agent for assistance. Other specialised connection accessories are available as options.Ask your dealer for details.
TEMPERATURE:
regulation,and the surrounding ambient temperature,according to which it varies its charging output voltage parameters. Should the internal temperature rise excessively due to restricted ventilation or extreme ambient conditions,the charging output will be reduced automatically until the internal temperature has stabilised at a safe level.Some models of this charger have a built-in cooling fan.Should the fan be jammed or out of order, the charger will be disabled and should be sent to a service agent for checking and repair.The charging output voltage parameters are increased or decreased according to decreases or increases respectively in the monitored ambient temperature,the nominal voltage parameters for each stage of charging being set at a 20°C (68°F) datum.On removal of the ambient temperature sensor which is plugged in at the rear of the charger,the voltage parameters will revert to their default settings as enumerated in the «Charging Procedure» text below. For more exacting applications,the standard plug-in sensor can be removed and replaced by an optional 2m long probe whose NTC thermistor tip when taped to the battery casing affords precise monitoring of the actual battery temperature for optimum voltage management.Order reference AMPROTPRO2.
FUSES:
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.Should the input protection fuse blow, check the input power cable and plug for damage or wear.
Replace any burnt fuse only with a new fuse of identical type and rating.
The charger is electronically protected against short-circuited output and inverted connections,and sparks due
The fuse in the cordset is intended to protect against overheating of the cordset and/or the
short across the cordset wires.The charger is itself electronically protected against this.

Charging procedure
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 110 to 120V. 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 sulfated 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 output until the monitored voltage rises to 14,4V (at 20°C or 68°F) 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 or 68°F) 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.
7) Disconnect the AC mains before disconnecting the battery connections.The circuit will instantly disable the charging output on disconnection of the battery,in any event.
8) Refer to the following section on application hints and interpretation of LED indications to obtain the most effective use of this advanced charger.
APPLICATION HINTS AND INTERPRETATION OF ‘LED’ INDICATIONS OF BATTERY STATUS
General hints:
operation and that have not been damaged through extended non-use,physical misuse or internal defects. Non-use of a battery for an extended period during which the battery is left to self-discharge without being re-charged causes internal chemical change (‘sulfation’) which may be irreversible. Failure to maintain the correct electrolite levels within batteries requiring occasional topping up with distilled water is also likely to result in irreversible battery damage. All unused batteries will maintain their charge best when stored in a cold or cool environment (but do not freeze). The warmer the surroundings the faster the battery will self-discharge.

1) Once you have connected the charger to your battery,LEAVE it connected for the maximum time given for the battery size in the table below,OR,until you observe a steady MAINTAIN LED indication.If you do not know the rated capacity of the battery,use the category indications in the table (see § 9).In most cases recharging of a discharged battery is indicated by a steady BULK charging LED for not more than the «maximum» time indicated in the table,followed by the ABSORB LED,and finally by a steady MAINTAIN LED. When the steady green MAINTAIN LED indicates,you can safely the battery connected to the charger for longer than the «maximum» time indicated below,however, unless a steady MAINTAIN indication is observed, there may well be some defect or problem within the battery, in which case there is no point in leaving it connected any longer.
2) No LED indication at all when the charger is connected to mains, switched on, and connected to the battery: see «Charging Procedure», clause 3.
3) Only the POWER ON LED is indicating:see «Charging Procedure» clause 4.
4) Steady BULK mode LED indication : LEAVE connected for up to the «maximum time» given below or until the green
MAINTAIN LED indicates steadily, if sooner. In most cases,the charging program will bring the battery to fully charged «MAINTAIN» status within the time period given in the «normal hours» column in the table below.If the green MAINTAIN LED does not indicate within the «maximum time»,the battery is probably damaged internally.
5) Steady green ABSORB LED:The ABSORB LED indicates that the battery is about 70% charged.At this stage a starter battery could start a vehicle if essential, but it is best to leave it connected until the MAINTAIN LED lights.Deep cycle batteries (for golf caddies and battery-driven vehicles) are also best left on charge until the MAINTAIN LED lights. If the battery is being charged off-vehicle and charging has continued past the «maximum time» per the table below,the battery may have internal damage.Disconnect the battery and have it tested by a professional.
6)ABSORB and MAINTAIN LEDs alternating:If the battery is being charged off-vehicle it may have internal damage. Leave it connected for the «maximum time» per the table and if the condition persists,disconnect the battery and have it tested by a professional.
7) Steady green MAINTAIN LED : the battery is fully charged and ready for use.You may leave it continuously connected to the charger if you wish to maintain it fully charged over a period of non-use,even over a few months.
NOTE: if a steady green MAINTAIN LED indication occurs immediately upon connection of a battery known to have been badly discharged or unused for some months prior to connection,the battery may well be deep-discharged.In such cases, leave it connected for the “maximum time”per the table. If flashing or pulsing of the charging LED’s occurs during this time,refer to clause 6 above.If the battery proves unusable thereafter,take it to a professional service dealer for testing and/or recycling.
8) Approximate average charging times are shown in the table.«Normal time from flat» is the average charging time to recharge a flat battery discharged to the extent it will not turn the engine. «Maximum time» is the time needed to restore a totally flat battery to fully charged status, for example a battery left without charge in storage for many months or a battery totally discharged by a connected load such as headlights being left on for a week.The charger will attempt to recharge any battery retaining at least 2 Volts (i.e.sulfated) though a significant degree of sulfation will prolong charging time and may make this impossible.
