There are self-resetting thermal overloads in
the input and output circuits.
Prolonged charging in excess of the
maximum continuous rating may cause the
thermal overload to operate, switching the
charger output off.
If this occurs, switch off the charger
and allow it to cool. The overload will
automatically reset and allow charging to
continue. However, if the thermal overload
repeatedly operates, it is possible that the
battery is faulty and should be checked with
a hydrometer and/or Arlec Battery Tester
BT831.
The charger is also provided with fuse
protection in the input circuit, which will not
blow in normal operation. If the fuse blows,
replace only with a fuse of identical type
and rating. Repeated fuse blowing indicates
a possible fault in the charger. In these
circumstances, you should contact an
Authorised Service Agent.
BANK CHARGING
Several batteries may be charged
simultaneously by connecting each of them
in parallel with the charger, using separate
jumper leads for the purpose.
Charging time is calculated by adding the
individual capacities of the batteries in the
bank and dividing this sum by the continuous
current rating of the charger.
CHARGING TIMES
In practice batteries will have some residual
charge and will vary in age, condition and
internal resistance, which will alter the
actual charging time.
However as a rough guide, approximate
charging time can be calculated by dividing
the rated capacity of the battery by the
continuous current rating of the charger,
e.g. 46 ampere hour battery requires 6 hours
at 7 amps.
SAFETY INFORMATION
Warning
Working in the vicinity of a lead acid battery
is dangerous due to the emission of explosive
gases. These explosive gases can be ignited
by a spark, cigarette or naked flame such as
a cigarette lighter or matches.
•
Keep sparks and naked flames away from
battery at all times.
•
Never smoke or light a cigarette near
a battery.
•
Take extreme care with metal objects and
tools including items of jewellery such as
rings and watch bands. Metal objects
touching the battery terminals may cause
sparks or serious heat burns to the user
or wearer.
•
Do not allow tools to drop on the battery
and never temporarily place tools on top
of a battery.
•
When testing or working on or around a
lead acid battery it is advisable to wear
protective eye glasses.
•
When testing or charging a lead acid
battery, ensure that the area you are
working in has plenty of ventilation.
Never test or charge a battery in a
confined area.
•
Do not use the charger in the rain or
expose it to water from hoses or
sprinklers.
Lead acid batteries contain Sulphuric Acid.
If acid contacts the skin or clothing, flush
immediately with large amounts of water.
In case of accidental eye contact with
battery acid, flush eyes for at least five
minutes with clean water. The eyes should
be submerged under water and kept open.
See a doctor immediately. Do not use eye
drops or other medication unless instructed
by a doctor.
This charger is designed to charge 12 or
24 volt automotive lead-acid batteries
of capacity in the range 40 to 160 amp-hours.
Do not attempt to charge batteries of other
types.
