Interacter Battery Charger
The Interacter 24/25 battery charger, used on
machines before serial number T5003-117, is a
three-stage, microprocessor-controlled 24V 25A
charger, with short circuit and reverse battery
protection, constant current, and constant voltage
with temperature compensated charging voltage.
There is no need to switch off the charger once the
batteries are charged, as the charger senses the
condition of the batteries and automatically
switches into a float or standby mode.
The charger is protected with a 10A slow blowing
fuse, located behind a small panel just below the
AC input connector.
There are 7 LEDs on the front panel, any
combination of which indicates the state of battery
charge or charger operating condition. Listed in the
next column, in order from top to bottom as seen
on the charger case, is an explanation of what
these LEDs indicate.
When using the charger, be sure the AC supply
circuit is grounded.

Description
Illuminates when charge current
is 80% of chargers nominal rating.
Illuminates when charge current
is 60% of chargers nominal rating.
Illuminates when charge current
is 40% of chargers nominal rating.
Illuminates when charge current
is 20% of chargers nominal rating.
NOTE: If the batteries are fully
discharged, all of the above listed
LEDs will illuminate at the same
time; if the batteries are not fully
discharged, not all will illuminate.
Illuminates when battery is
connected correctly and AC power
is present. LED turns off when
battery reaches first voltage limit.
Illuminates during charging when
timer is running; battery voltage is
held constant at this while this LED
is on, minimum one hour OR one
hour plus half time required to
reach first voltage limit.
Illuminates at end of charging
cycle, indicating batteries are
charged and ready for use, and
will remain on as long as AC power
and batteries remain connected,
maintaining charger in float or
standby mode.
NOTE: If the Green LED flashes
constantly at the end of the charge,
this indicates an override timeout
fault condition, which happens if
the charge cycle is not completed
within 18 hours of charge start,
after which the charger will not
output any current. This is caused
by a charger low output current
fault OR a shorted cell in a battery.
