Operation of the IBC320 charger is very simple. It is intended to operate fully unattended,
and will attempt to recover from any fault, such as Charger Over-Temperature, Battery Over-
Temperature, Insufcient Input Voltage, Power Failure and more.
In a xed installation, presumably the charger is already connected to the battery or batter-
ies. In a portable application, connect the charger to the battery before turning it on. Once the
battery is connected to the charger, conrm that the ‘REV’ LED is NOT illuminated and turn on
the main power switch on the rear panel. Conrm that the ‘AC’ LED IS illuminated (Green) and
press the Power button on the front panel.
Operation
Note: The charger has two operating modes – Battery Charger and Power Supply. If
you are not sure which mode the IBC320 is in, press and hold the lighted Power button
for 3 seconds. If you hear two beeps, it is in Power Supply mode. If you hear one beep,
it is in Battery Charger mode. Make sure it is in the correct operating mode for your
requirements
The charger will go through a startup sequence that consists of turning the 6 LEDs controlled by
the computer all Red, then all Green. Then it will step through the 3 program settings described
in Setup so it is easy to see how the charger is programmed. The Power button will illuminate
once the charger has completely turned on.
The charger will begin to charge the battery or batteries according to the settings that were
selected during the setup. If no battery was detected during the startup of the charger, it will not
turn the outputs on and will indicate a failure.
If the AC power fails or is disconnected, the charger will resume charging the batteries when AC
is restored.
The IBC320 Charger is so efcient that is does not need a cooling fan to operate at maximum
performance. However, in a very hot ambient environment the microprocessor will reduce power
output as needed to keep the circuitry operating at a safe and reliable temperature. In extreme
cases, the charger may shut off completely until it cools sufciently to resume operation.
