3) During normal machine usage with the engine running, the batteries are on continuous recharge,
except when the control system decides that additional electric power is required in order to
maintain drive/function speed.
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
The capacity of the 110V supply must be capable of 3.5kVA (32A current); hence a small hand-tool
transformer must not be used with the battery charger.
Note; charger output will fall if air temperature is below 0°C or above 50°C.
Fault Conditions
If a fault occurs, count number of flashes between pauses and refer to table:
Red LED status
One flash
Two flashes
Three flashes
Four flashes
Five flashes
Six flashes
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
current carrying capacity, which will again lead to a reduction in the chargers efficiency. Both of these
can result in over-heating of the cable with an increased risk of fire, short circuits or damage to the
components themselves.
