InteliCharger 240 24 Reference Guide

This option is not applicable for NiCd–NiMH batteries.
Note:
It is allowed to set this option when charger is powered.
Life Test function
Charger check periodically battery internal impedance and determines whether the battery
is sulphated when Life Test function is enabled. Test is performed every two hours during
float charging stage. Two consecutively checks with the same result have to be performed
prior Life Test results are announced. If a sulphated battery is detected, this fault is
signalized by battery or charge fail indicator
, battery or charge fail relay is in failure
mode (pin 6–8 closed) and diagnostic indicator
is blinking 5 blink code. During fault
signaling the charger operates as usual and continues with charging the battery.
Note:
It is essential to connect battery properly to ensure right results of battery life test function.
Power supply mode
The charger is switched automatically to power supply mode when there is no battery connected to charger
battery output. Output voltage is the float charging voltage and depends on battery type selected. See
Battery
type selection (page 11)
for details. Maximum output current in power supply mode is the same as maximum
charging current.
Battery care
The Battery Care philosophy is based on algorithms that implement rapid and automatic charging, battery
charge optimization, flat batteries recovery and real time diagnosis. The realtime auto-diagnostic system
monitors battery and charging proces during the installation and operation.Faults such as cells in short circuit,
accidental reverse polarity connection, disconnection of the battery, can be easily detected and fixed by help of
blink code of diagnosis indicator. The charger is suited for all battery types. It is possible to choose predefined
charging curves for Open Lead Acid, Sealed Lead Acid, Gel and NiCd–NiMH battery. Battery reliability in time is
guaranteed by continuously testing the internal impedance status. It avoids any possible risk of damages and
grants also a permanent, reliable and safe connection of the battery to the charger. The system, through a
battery stimulation circuit with algorithms of evaluation of the detected parameter, is able to recognize batteries
with a short-circuited cell.
Charging curve
Automatic multi-stage operation and real time diagnosis allows fast recharge and recovery of deeply discharged
batteries, adding value and reliability to the system hosting the InteliCharger 240 24 device. The type of
charging is Voltage stabilized and Current stabilized IUoU.
Each of four charging stage is identified by a flashing code on the Diagnosis indicator.
To maintain the output battery voltage in lower levels, don’t enable boost charging. (No jumper set in position 5.)
There are four charging stages:
recovery
2
bulk
absorption
float.
