HOW THE LINK 2000-R CHARGES
See page 18 of LINK 2000 manual for details of the Ideal Charge Curve.
The LINK 2000-R uses our Ideal Regulator Output Module to control the
alternator to conform to the Ideal Charge Curve’s four defining cycles; Charge, Accep-
tance, Float, and Equalize. The following discusses details of each of the cycles.
NOTES: 1) Terminal number references are for the Regulator Terminal Board.
2) Voltage values given for 70
0
F and liquid lead acid batteries.
TURNING THE REGULATOR ON
The regulator is turned on by supplying 12V to the REG ON (Brown wire)
terminal.
It must be on only when the engine is running. See Page 12.
DELAY START-UP
Behavior: No Output on the Field Terminal (Blue wire).
Two second delay allows time for the engine to start.
RAMPING UP
Behavior: Output of Alternator increases over a 20 second period.
Ramping up the alternator output avoids shock-loading the belts with full
alternator output. The output on the FIELD terminal is increased over a 20 second
period until the Alternator Current Limit (Default Value 100A) is reached. The
Charge Cycle now begins
CHARGE CYCLE
Behavior: Alternator at max and Battery Voltage is increasing.
The Charge Cycle insures fast charging without overloading the alternator. The
Alternator Current limit will not be exceeded. The FIELD output is varied to hold
the alternator at its current limit until the Charged Voltage is reached. When The
Charged Voltage has been attained by either battery #1 or #2, the Acceptance
Cycle begins.

ACCEPTANCE CYCLE
Behavior: Battery Amps falling, Voltage at 14.4V (Voltage depends on
ambient temperature setting).
The Acceptance Cycle guarantees thorough charging by continuing to charge
the battery until the charging current becomes a small percentage of battery
capacity (2%). The alternator output is varied to maintain the battery at the
Acceptance Voltage. During the Acceptance Cycle the alternator current limit
will not be exceeded, even if a heavy load is placed on the system.
When the batteries have reached the Acceptance Voltage and the current is
below 2%, the Acceptance Hold Cycle begins. If the Acceptance Cycle has
lasted 3.5 hours, the Float transition cycle begins, even if the charged parameters
have not been met. If the voltage of the batteries falls below the Acceptance
Voltage for more than 2 minutes, the charge cycle starts again.
