ACCEPTANCE HOLD CYCLE
Behavior: Voltage at 14.4V. Battery Amps below 2%;
The Acceptance Hold Cycle insures that the battery has accepted as much
charge as it can. During the Acceptance Hold cycle the Charged Voltage is
maintained and charging current is monitored. Both the Charged Voltage and the
Charged Current % must continue to be satisfied for 10 minutes for the
Acceptance Hold Cycle to end. The Acceptance Hold Cycle is also terminated
after 20 minutes from its beginning even if the battery current has not stayed
below the Charged Current for the entire time.
If the voltage of the batteries falls below the Charged Voltage for more than
2 minutes the charge cycle starts again.

FLOAT TRANSITION CYCLE
Behavior: Battery Amps below 2%; Voltage is falling from 14.4V to 13.5V.
The Float Transition Cycle is intended to provide continuous alternator output
during the cycle change from Acceptance to Float. Avoiding an abrupt transition
between these voltages insures that electronic tachometers supplied from the
alternator continue to work during the transition.
Once the Float Voltage value is reached, the Float Cycle begins.
FLOAT CYCLE
Behavior: Battery Amps below 2%, Voltage constant at 13.5V.
During the Float cycle the Float Voltage is maintained. The alternator will
supply up to its current limit to maintain the Float Voltage.
RESTARTING THE CHARGE CYCLE
MANUALLY: The Ramp Up Cycle may be manually restarted by turning
off the REG ON terminal and turning it back on again.
AUTOMATICALLY: The Charge Cycle is automatically restarted if the
voltage of the battery being charged drops 0.2V below the Float Voltage (0.3V
when charging with the inverter/charger) for more than 2 minutes.
EQUALIZE CYCLE
Behavior: Battery Amps constant at 4%, (16A max) Voltage is rising to a
maximum of 16.0V. (Limited to Acceptance voltage for Gelled Batteries.)
To start the Equalize Cycle press the SET UP BUTTON for five seconds until
the LED begins to flash. Now press both the VOLTS and the A HRS BUTTON
simultaneously. Hold them both down for five seconds until the Red CHARGE
LED begins to flash and the “E” in the display goes out. To terminate the Equalize
Cycle and force the system into the Float mode repeat same procedure. The cycle
automatically terminates after 3.5 hours initiation or when the current drops to 2%
of capacity at 16.0V. (Equalize terminated in eight hours if using the Freedom
charger.)
The Equalize Cycle is a controlled overcharge to remove Lead Sulfate which
is not removed during normal charging. Liquid batteries should be Equalized
every 30 days when in cycling service.
