SUPPLEMENT TO THE LINK 2000 OWNER'S MANUAL

must be familiar with that manual before using the LINK

For use only with externally regulated

12- or 24-volt "P" Field type alternators.

See "Required Reading," page 8.

FRONT PANEL AND STATUS LIGHTS

The front panel operation of the LINK 2000-R is exactly the same as described in the LINK 2000 owner's manual, with the exceptions noted below.

i4.40

Status lights indicate which cycle the regulator (and/or the charger) is in. The AC light will be OFF if there is no external AC input.

Selecting TIME when the alternator regulator is operating displays the alternator output current. The current is displayed with an " preceding the value.

FRONT PANEL SWITCHES

The operation of the front panel is the same as the LINK 2000 with the exception of the TIME switch. When the alternator regulator is on (REG ON energized) and TIME is

selected, the alternator output current is displayed. It is preceded with the character " For example, an alternator output current of 100 amps would be displayed as AI00.

A".

STATUS LIGHTS

The status lights on the front of LINK 2000-R use LEDs (light-emitting diodes) to indicate which cycle the alternator regulator is in during charging. The meaning of the lights is the same as described in the LINK 2000 installation manual. The only difference is that when there is no external AC power available, and indicate the charge cycle for the alternator regulator. If external AC power is available, the charger is turned the cycle of both the charger and the alternator regulator.

AC IN: Green LED on when AC is present. CHARGE: Red LED on when charger/alternator is in bulk CHARGE Cycle.

ACCEPT: Orange LED on when charger/alternator is in ACCEPTANCE Cycle. FLOAT: Green LED on when charger/alternator is in FLOAT Cycle.

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 the Ideal Regulator Output Module to control the alternator to conform to the Ideal Charge Curve’s four defining cycles; Charge, Acceptance, Float, and Equalize. The following discusses details of each of the cycles.

TURNING THE REGULATOR ON

The regulator is turned on by supplying 12 V or 24 V to the REG ON (brown

wire) terminal.

It must have power only when the engine is running. See page 13.

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 100 A) is reached. The Charge Cycle now begins. If the acceptance voltage is reached before the current limit, the Acceptance Cycle begins.

CHARGE CYCLE Behavior: Alternator current at maximum and battery voltage increasing.

The Charge Cycle ensures fast charging without alternator overload. The alternator current limit will not be exceeded. The FIELD output is varied to hold the alternator at its current limit until the acceptance voltage is reached. When the acceptance voltage has been attained by either battery, the Acceptance Cycle begins.

ACCEPTANCE CYCLE Behavior: Battery amps falling, voltage at 14.4 V for 12 V systems, 28.8 for 24 V. (Voltage depends on battery type and ambient temperature settings.)

The Acceptance Cycle guarantees thorough charging by continuing to charge the battery until the charging current becomes a small percentage of battery

capacity (2% default). 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 Cycle begins, even if the charged parameters have not been met. If the voltage of either battery falls below the acceptance voltage for more than two minutes, the Charge Cycle starts again.

ACCEPTANCE HOLD CYCLE

Behavior: Voltage at 14.4 V (28.8 V for 24 V), battery amps below 2%.

The Acceptance Hold Cycle ensures 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 two minutes, the Charge Cycle starts again.

FLOAT CYCLE Behavior: Battery amps below 2%, voltage constant at 13.5 V (27 V FOR 24 V). (Voltage depends on battery type and ambient temperature setting.)

During the Float Cycle the float voltage is maintained. The alternator will supply up to its current limit to maintain the float voltage and supply DC loads.

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. This will require you to turn off the key switch supplying REG ON or shutting off and restarting the engine if REG ON is supplied by an oil pressure switch.

AUTOMATICALLY: The Charge Cycle is automatically restarted if the voltage of the battery being charged drops 0.2 V (0.4 V for 24 V) below the float voltage (0.3 V when charging with the inverter/charger) for more than two minutes.

RED LED

FLASH

EQUALIZE CYCLE Behavior: Battery amps constant at 4%, voltage is rising to a maximum of 16.0 V when charging with the alternator and 16.3 V when charging with the inverter/charger. (Limited to acceptance voltage for gelled batteries.)

To start the Equalize Cycle press the SETUP 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 cycle, repeat the same procedure. The cycle automatically terminates 3.5 hours after initiation, or when the current drops to 2% of capacity at 16.0 V. (Equalize terminated in eight hours if using the inverter/charger.)

The Equalize Cycle is a controlled overcharge to remove lead sulfate that is not removed during normal charging. Liquid batteries should be equalized about every 30 days when in deep cycling service.

EQUALIZING CAUTIONS!

Turn off sensitive electronics before equalizing.

Equalizing causes the battery to gas. You should check the battery electrolyte before and after equalization. Do not over-fill before equalization as the electrolyte may expand and cause it to flow over the tops. You should be present during this type of charging. Hydrogen and oxygen gas is generated during equalization. Make sure

there is adequate ventilation.

Batteries should not be equalized every charge/discharge cycle. Normally, the battery is cycled between 50% charged and the 85% to 95% charged level reached by the normal Charge and Acceptance Cycle. Every 30 days, though, the batteries should be equalized to regain full capacity and extend life.

To equalize, first go through a complete Charge and Acceptance Cycle. Check the electrolyte level, but do not overfill. Re-check and top off the electrolyte

Remember, equalizing is constant current charging with a small regulated current that permits a higher maximum voltage. The goal is to use a small current and gradually let the battery rise to its maximum voltage.

EQUALIZING GELLED BATTERIES

Gelled batteries are not normally equalized. However, if the battery has been severely discharged, the voltage of the battery may easily reach the acceptance level with a very small current. In fact, the current may be less than the 2% required to terminate the Acceptance Cycle. This can cause the system to believe that the battery is full and switch to the Float Cycle. Equalization may be the only way to get the battery to accept a charge. Be sure that the battery TYPE # is set to #1 or #2 before using this cycle on gelled batteries. voltage but the cycle lasts for 3.5 hours. (Eight hours if using the Freedom charger.) Please consult your battery manufacturer regarding the appropriateness of this cycle for their batteries.

The equalization voltage is limited to the acceptance

after equalizing.
