The CHARGER section allows for adjustment of the battery charger’s operation to match the requirements of the batteries used. OutBack’s default battery charging set points may not be correct for the type of batteries being used. Please contact the battery manufacturer for correct ABSORB, FLOAT and EQUALIZE voltages. See the BATTERY CHARGING INSTRUCTIONS on page 23 for guidelines on how to set some of these values.
The FX’s battery charger includes five stages. BULK raises the battery voltage to the ‘Absorb Setpoint’. ABSORB sustains the battery voltage for the ‘Absorb Time Limit’. The charger then goes into SILENT mode (no charging) until the battery voltage drops to the ‘Float Setpoint’. FLOAT sustains this battery voltage for the ‘Float Time Period’. The charger then goes into ‘Silent’ mode until the battery voltage drops to the ‘Refloat Setpoint’. REFLOAT will start another FLOAT charge. There are additional screens for “Equalize Setpoint’ and ‘Equalize Time Period’. An equalize charge must be manually started. The time limits that it spends in the various stages are adjustable to provide control and maximize the performance of the battery charger and battery system.

Once the password has been correctly entered, the ADV - CHOOSE PRODUCT is displayed. Selecting <FX> allows adjustment of the FX’s advanced programming.
Selecting <CHGR> allows adjustment of the battery charger set points and operation.
The CHARGER LIMIT is the maximum amount of AC current that will be used by the FX to power the battery charger. In most systems this setting will not need to be changed. This setting has a range as low as 0.0 aac and as high as 6.0 aac to 10.0 aac (depending on the model) in 0.5 aac increments.
The ABSORB SET POINT is the voltage that the batteries will be charged to during the first stage of the charging process. This stage of charging raises the battery voltage higher than the nominal battery voltage and allows the batteries to regain their charge. The ‘Absorb Time Limit’ must be long enough for the batteries to regain 100% of their charge.
The ABSORB TIME LIMIT can be adjusted to provide enough time at the ‘Absorb Setpoint’ to achieve a fully recharged battery. For large batteries a longer time may be required – small batteries may require a lower setting. The FX automatically reduces the ‘Absorb Time Limit’ when the charger is connected to a partially charged battery. This setting has a range between 0 hours and 24 hours in 0.1 hour increments.
The FLOAT SET POINT is the voltage that the batteries will be ‘trickle’ charged to. This charge will finish the charging process by putting the last few percentage points of charge into the batteries. This set point can be adjusted to match the specific requirements of the batteries being charged. This setting has a range between 12.0 vdc and 15.0 vdc in 0.1 vdc increments.
The FLOAT TIME PERIOD can be adjusted to set the amount of time that the battery is held at the ‘Float Setpoint’. For large batteries a longer time may be required – smaller batteries may use a lower setting. Once the battery has been held at the ‘Float Setpoint’ for the ‘Float Time Period’, the battery charger goes silent and provides no charge to the battery. This setting has a range between 0 hours and 24 hours in 0.1 hour increments.
The REFLOAT SET POINT voltage is used to “trigger” the battery charger back into another FLOAT cycle when the battery voltage falls to this set point. This can provide maintenance charging of batteries and is also useful when intermittent DC loads are operated from a battery system and an AC source is available. This setting has a range between 12.0 vdc and 13.0 vdc in 0.1 vdc increments.
The EQUALIZE SET POINT voltage can be set for a high voltage to
The EQUALIZE TIME PERIOD can be adjusted to limit the amount of time that the battery is equalized. The timer starts to advance once the battery voltage exceeds the absorb voltage set point. Once the timer reaches the equalize time period, the charger goes into the silent stage of the charging process. This setting has a range between 0 hours and 24 hours in 0.1 hour increments.
