When the regulator is first turned on, theprocessor performs a quick one-second self diagnostic assessment. Following that diagnostic, the MC-614 initiates the selectedbattery charge program. Note that the Factory-set default values mentioned below correspond to the UFP battery programwhich is enabled by default. The battery program is as follows.1. Start Delay. Controls time between regulator activation and the start of charging. Factory set at one second. Useradjustable with dLc (See page 14)2. Soft Ramp. Gently increases target voltage from current battery resting voltage to the Bulk Charge stage target at a fixedrate of 0.04 volts per second. This stage typically takes 1-2 minutes to complete.3. Bulk Charge. The most aggressive of the charging stages. Target voltage is held to a preset level for a set time period,both of which are specified by the battery program selected. Factory-set values are 14.1 Volts for 0.3 hours (18 minutes),and are adjustable with bv and b1c, respectively (See page 14).4. Calculated Bulk Charge. Target voltage is maintained at Bulk level. The regulator calculates battery condition byconstantly monitoring field duty cycle, battery sense voltage, and an internal timer. Depending on these conditions, theregulator will stay in Calculated Bulk stage between 2 seconds and a fixed 6 hour time limit. If the 6 hour limit is exceeded itwill automatically transition to the following stage. The field duty cycle target (FBA) is user adjustable. Factory set default is65% (See page 15).5. Ramp to Absorption. Gradually changes the target voltage from the current battery sense voltage to the AbsorptionCharge stage target at a fixed rate of 0.02 volts per 7 seconds. This stage typically takes 1 minute to complete.6. Absorption Charge. The alternator output is held at a set voltage for a set time period, specified by the battery programselected. Factory-set values are 13.9 volts for 0.3 hours (18 minutes) and are adjustable with Av and A1c, respectively (Seepage 14).7. Calculated Absorption Charge. Target voltage is maintained at the Absorption Charge level. The regulator calculatesbattery condition by constantly monitoring field duty cycle, battery sense voltage, and an internal timer. Once all conditionsare met, the regulator will transition to the next stage. The time duration of this stage is between 2 seconds and 6 hours,depending upon battery condition. If the 6 hour limit is exceeded the regulator will automatically transition to the followingstage. The field duty cycle target (FBA) is user adjustable. Factory set default is 65% (See page 15).8. Ramp to Float. Gradually changes the target voltage from the current battery sense voltage to the Float Charge stagetarget at a fixed rate of 0.02 volts per 3 seconds. This stage typically takes about 1 minute to complete.9. Float Charge. The alternator output is held at a preset voltage for a set time period, again, specified by the battery programselected. Factory-set defaults are 13.4 volts for 0.3 hours (18 minutes), adjustable with Fv and F1c, respectively (See page14 & 15).10. Calculated Float Charge. Target voltage is maintained at the Float level. The regulator can respond to an increasedcharge demand by reverting to the Absorption Charge stage if the conditions warrant. The battery condition is judgedby constantly monitoring field duty cycle, battery sense voltage, and an internal timer. The regulator will stay in theCalculated Float charge stage a minimum of 2 seconds and up to 6 hours. If the 6 hour limit is exceeded the regulator willautomatically revert to the absorption charge stage. The field duty cycle threshold (FFL) is user adjustable. Factory setdefault is 65% (See page 15).1 sec. 60 sec. 18 min. Up to 6 hrs. 18 min. Up to 6 hrs. 18 min. Up to 6 hrs. 18 min. Up to 6 hrs. 18 min.
