Note:
1) If the charger is reconnected to the power supply shortly after it has gone through its full
charging cycle, the
transformer type charger may show a Red light although the batteries may
be fully charged. Alternatively, the digital charger will show a Green 50% lamp, immediately
followed by the Green 75% lamp. The charger would then repeat its complete cycle again at an
accelerated rate, depending on the time difference between connection, reconnection and level
of battery charge.
2) Some machines are fitted with a Battery Management System, which permanently monitors the
condition of the batteries. When the batteries become discharged to 20% of their capacity the
management system will begin to "shut down" the hydraulic power packs. This causes the
drive/boom operating system to alternately stop and start, signalling to the operator that re-
charging is necessary. However, there is sufficient power remaining to enable the operator to
drive slowly to the nearest charging point.
Should the operator ignore the onset of the battery discharge warning the "shut down" of the motors
will continue, until the machine is rendered in-operative.
Immediate charging will then be required.
CHARGING LIMITATIONS
Transformer Charger: - Battery charging times will increase slightly if using an 110V supply as
opposed to a 240V supply. This is due to the connection of the primary coils being in parallel, which in
effect only allows the transformer to see 220V. Similarly, the capacity of the 110V supply will decide
the input current available; hence a small hand-tool transformer will not operate the battery charger
efficiently, therefore: - charging times will increase further due to input limitations.
Digital Charger: - The capacity of the 110V supply must be capable of 2kW (18A current); hence a
small hand-tool transformer will not operate the battery charger.
Digital Charger Fault Display
Note; If a fault occurs, the charger emits an audible warning. In addition, if the fault is rectified the
charger will restart automatically.
Attention should also be given to the use of extension cables as power leads. Excessive cable lengths
from the supply point to the battery charger will result in significant voltage drop, leading to a reduction
in the chargers efficiency. In addition, inadequate sized cable cores will have a limiting effect on its
