POWER SUPPLY MODE Connect the unit to the load and AC power source. Press the Power Button on the unit’s front panel. The charger will go through its startup sequence. All 6 microprocessor-controlled LEDs flash red and then green. When the Power Button starts glowing, the sequence is complete.
Green - Ground All connections should be made inside of an appropriate junction box with appropriately rated circuit breakers used in the circuit panel to feed power to the IBC320. See Specifications for the maximum input current and recommended fuses.

DC OUTPUT CONNECTION This unit is equipped with a pair of Phoenix VDFK Terminal block connectors to serve as a DC Output connection for connection to battery banks. The connection can support up to two connected battery banks. The polarity for these connections can be found on the unit’s front panel label. CAUTION: IF YOU ARE CHARGING TWO BANKS OF BATTERIES, THEY MUST SHARE A COMMON GROUND!

Connection CONNECTION INDICATORS 1. Connect the charger to the batteries as indicated under Installation. TEMP LO V 2. Check the POL LED on the front panel. If it is glow- ing red, the battery is connected in reverse polarity. Correct the connection to the battery (The red terminal should go to Positive and black to Negative).

BATTERY TYPE BATTERY TYPE INDICATORS The Battery Type parameters controls the type of charging profile that the unit will use to charge the battery. TEMP LO V TEMP LO V Different types of batteries have different optimal charging voltages and currents due to their construction and chemical composition.

DEFAULT BATTERY TEMPERATURE DEFAULT BATTERY The Default Battery Temperature TEMPERATURE INDICATORS parameters controls the charger’s estimated value of the battery TEMP LO V TEMP LO V temperature. The optimal charging voltage of a battery will decrease as its temperature increases. The charger uses this value to calculate DEFAULT WARM (21°C/70°F) its charging compensation if there...

Front Panel Adjustments Using the two switches between the Program and Select buttons on the front panel, you can select whether a 2-stage or 3-stage charging profile is used to charge the batteries and control the battery charger’s behavior when the charging cycle ends. END-OF-CHARGE SELECT The End-of-Charge (EOC) select switch controls the charger’s behavior after it finishes charging the battery/ batteries.

Charging Profiles This unit has both two-stage and three-stage charging capability. You can choose which charging profile is used during operation by using the Stage Select switch on the front panel. Below are explanations of the two profiles: TWO-STAGE CHARGING •...

Equalize Cycle If a battery’s cells are left discharged for too long, sulfate crystals can form on the plates interfering with their conductance. This reduces the battery’s capacity and recharging ability. An equalize cycle is a deliberate overcharge of the battery at high voltage (110% of float voltage) and low current (10% of standard output) to force undercharged cells to match charge of the good cells in the battery.

Battery Temperature Sensor This unit is supplied with one battery temperature sensor. This sensor communicates the temperature of the battery to the charger and is required to access the charger’s voltage temperature compensation, batttery over temperature alarm and equalize cycle functions. Pictured: An Battery Temperature Sensor (B-TEMP) BATTERY TEMPERATURE SENSOR CONNECTION This unit is equipped with 2 RJ45 Telephone Jack connector to connect to up to two battery...

Maintenance This charger requires no maintenance other than the occasional wipe down to remove dust that could reduce its ability to dissipate heat. Carefully blow air through the cooling vent to remove any dust buildup inside the unit. Dry Contact Relay The charger can be fitted with a 1 amp dry contact relay to indicate charger status to a monitoring system.
Troubleshooting The IBC320 is designed to provide years of reliable service and to auto-recover in the event of an operational failure. In the event of malfunction, the unit is fitted with eight LED indicators and an audible alarm to help diagnose the cause of the issue. Below is a list of potential issues, and how to repair them.

BLINKING FAULT INDICATORS Charger Failure Indication TEMP LO V The microprocessor has detected a condition that prevents the charger from operating. Try disconnecting the AC power and re-connecting it. If this does not clear the fault, the cause is likely an internal component failure and the charger will have to be returned for service CHARGER FAILED Battery Fail Indication...
