Regulator Operation
The ARS-5 regulator’s microprocessor controlled charging system uses a sophisticated, multi-stage profile to deliver optimal
charging, while protecting the batteries from overcharging damage. When the regulator is first turned on, the processor
performs a quick one-second self diagnostic assessment. Following that diagnostic, the ARS-5 initiates a charge program as
follows:
1.
Start Delay -
Factory set at one second. Can be user-adjusted to a maximum of 999 seconds in the regulator’s advanced
programming mode. See Advanced Programming section for adjustment instructions.
2.
Soft Ramp -
Gently increases voltage to bulk preset levels based on battery program selected.
3.
Bulk Charge -
The most aggressive of the charging stages. Voltage is held at a pre-set level, specified by battery program
selected, for a set time period. Factory-set bulk time is 18 minutes. Adjustable in 1/10-hour increments.
4.
Calculated Bulk Charge -
Holds voltage at bulk level for six minutes, then calculates system condition by comparing
existing voltage, time at voltage, and field percentage to target values. If values are met, the regulator advances to the next
stage. If values are not met, the regulator continues to bulk charge and compares real-time to target values. The regulator
will continually update calculations until all values are met.
5.
Ramps down to Absorption voltage.
6.
Absorption Charge -
Regulator continues to control the alternator’s output voltage for an additional 18 minutes at
approximately 2/10-volts below bulk charging voltage. Adjustable in 1/10- hour increments.
7.
Calculated Absorption Charge -
Holds voltage at absorption level for six minutes, then calculates system condition by
comparing existing voltage, time at voltage, and field percentage to target values. If values are met, the regulator advances
to the next stage. If values are not met, the regulator extends the absorption charge and compares real-time to target
values. The regulator will continually update calculations until all values are met.
8.
Ramp down to Float.
9.
Float Charge -
Regulator continues to control the alternator’s output voltage for an additional 18 minutes, typically at one
volt less than bulk voltage (based on battery program presets). After that initial fixed time period, the regulator can respond
to increased charging demand by cycling to absorption voltage. After 12 hours of continuous operation, the regulator will
automatically revert to absorption voltage through calculated absorption and back to float charging stage.
