4.4.3.
Absorption
Reduces the current supplied to the battery and ensures that the battery has been completely charged without the risk of being
overcharged.
Analysis – Testing the battery while charging
4.4.4.
The charger shuts off power and measures voltage drop over a set time. If unacceptable readings are measured this may indicate an
internal short or other issue inside the battery.
If the battery has a fault the charger will stop charge, the charger will cut output and will not continue charging until it is either switched
off, or the battery is removed. Faulty Battery indicators will activate if the battery being charged is completely dead and cannot be
charged. Depending on what battery is being charged, 6V or 12V or 24V LED will flash if battery is faulty.
4.4.5.
Boost/ equalisation charge
Once the battery is fully charged, the charger will equalize all of the battery cells by providing a steady set voltage over a programmed
period of time, at low current.
Float charge:
4.4.6.
After the boost/equalisation charge stage, the current will drop to low amperage to maintain the battery in a fully charged and ready to
use state.
4.4.7.
Maintenance charge
After the float charge stage, the voltage will maintain at a constant level with a small pulse frequency. Current is dropped to a very low
level.
4.4.8.
Power Supply Mode:
This battery charger is fitted with a DC power supply mode. This mode will deliver a constant 13.5 Volts at 30/40 Amps and can be
used for powering 12V DC appliances, lighting or used for testing 12V devices. The DC power supply also has overload and short
circuit protection.
4.4.8.1.
To enter the DC power supply mode:
• Ensure unit is switched off before making any connections.
• Switch the 240V AC and the power switch on the unit ON.
• Press the MODE button twice until the DC SUPPLY LED indicator is illuminated.
• Connect the RED lead (Battery Clip) to the positive input on the device.
• Connect the Black lead (Battery Clip) to the negative input on the device.
• To switch off power supply; first turn the power switch on the back of the unit off, then turn off or unplug the AC power.
• Disconnect the DC power leads from the device.
• The DC power mode will automatically turn off and revert to Battery Charging when the charger is turned off and powered back on.
4.4.8.2.
WARNING: DO NOT ENABLE DC POWER SUPPLY MODE WHEN CONNECTED TO A BATTERY IN ORDER TO PREVENT
SEVERE BATTERY FAILURE.
5. MAINTENANCE
WARNING! After use and before performing maintenance, unplug and disconnect the battery charger.
‰
5.1.
Cleaning and user maintenance should be carried out by competent persons.
5.2.
Use a dry cloth to wipe all battery corrosion and other dirt or oil from the battery connectors, cords, and the charger case.
5.3.
Ensure that all of the charger components are in place and in good working condition, for example, the plastic boots on the
battery clips.
5.4.
Servicing does not require opening the unit, as there are no serviceable parts.
5.5.
All other servicing should be performed by qualified service personnel.
5.6.
If the mains cable is damaged, DO NOT use until repaired.
5.7.
Store the charger unplugged, in an upright position. The cord will still conduct electricity until it is unplugged from the mains.
5.8.
Store inside, in a cool, dry place.
DO NOT store the connectors clipped together, on or around metal, or clipped to cables. If the charger is moved around the shop or
8
transported to another location, take care to avoid/prevent damage to the cables, connectors and charger. Failure to do so could result
in personal injury or property damage.
