FRONT PANEL SWITCHES

The operation of the front panel is the same as theLINK 2000with the exception

oftheTIMEswitch. Whenthealternatorregulatorison(REGONenergized)andTIME

is selected, the alternator current is displayed. It is preceded with the character "A". For

exampleanalternatorcurrentof100AmpswouldbedisplayedasAI00.

CYCLE STATUS LIGHTS

TheChargeCyclestatuslightsonthe front of LINK2000-R indicatewhichcycle

the alternator regulator is in during charging. The meaning of the lights is the same as

describedintheLINK2000installationmanual. Theonlydifferenceisthatwhenthereis

noACpower available, andthe regulator is turned on, the cycle lights indicate the charge

cycle for the alternator regulator. If AC power is available, the charger is turned on, and

the alternator is also charging the battery, the cycle lights indicate the cycle of both the

charger and the alternator regulator.

SelectingTIMEwhenthealternatorregula-

tor is operating displays the alternator out-

putcurrent. Thecurrentisdisplayedwithan

Charge Cycle status lights indicate which

cycletheregulator(andorthecharger)isin.

The AC light will be off if there is no AC

input and therefore no charger operation.

FRONT PANEL AND STATUS LIGHTS

The front panel operation of theLINK 2000-R is exactly the same as described in

the LINK 2000 owners manual with the exceptions noted below.

AC IN: Green LED on when AC is present.

CHARGE: Red LED on when charger is in bulk Charge mode.

Flashes Red when charger is in Equalize mode.

ACCEPT: Orange LED on when charger is in Acceptance mode.

FLOAT: Green LED on when charger is in Float mode.

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 700F 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

alternatoroutput. TheoutputontheFIELDterminalisincreasedovera20second

perioduntil theAlternatorCurrentLimit(DefaultValue100A)isreached. The

Charge Cycle now begins

CHARGE CYCLE

ACCEPTANCE CYCLE

Behavior: Battery Amps falling, Voltage at 14.4V (Voltage depends on

ambienttemperaturesetting).

TheAcceptanceCycleguaranteesthoroughchargingbycontinuingtocharge

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

AcceptanceVoltage. Duringthe 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

lasted3.5hours,theFloattransitioncyclebegins,evenifthechargedparameters

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.

6/21/96

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

maintainedandchargingcurrentismonitored. BoththeChargedVoltageandthe

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.

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.)

6/21/96

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

batteryiscycledbetween50%charged and the 85%to95%charged levelreachedbythe

normal Charge and Acceptance cycle. Every 30 days, though, the batteries should be

equalized to regain full capacity and extend life.

ToEqualize, firstgothrougha completeCharge andAcceptanceCycle. Checkthe

electrolytelevelbutdonotoverfill. Re-checkandtopofftheelectrolyteafter Equalizing.

Remember, Equalizing is constant current charging with a small regulated

current that allows a higher maximum voltage. The goal is to use a small current,

not a high voltage.

Equalizing and Gelled Batteries

Gelled batteries are not normally equalized. However, if the battery has been

severelydischarged, thevoltageofthebatterymayeasilyreachtheAcceptancelevelwith

averysmall current. Infact,thecurrentmay belessthanthe 2% requiredtoterminatethe

AcceptanceCycle. Thiscancausethesystemtobelievethatthebatteryisfullandswitch

to the Float mode. Equalization may be the only way to get the battery to accept a charge.

BesurethatthebatteryTYPE#issetto#2beforeusingthiscycleongelledbatteries. The

equalizationvoltage is limited to the Acceptance level 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.

SPECIAL SET UP FOR LINK 2000-R

The following is a list of special set ups that may be necessary to tailor the LINK

2000-R to your system. Please see Pages 10-13 of the LINK 2000 Owners Manual for

details on how to use the FUNC mode.

F10 - ALTERNATOR CURRENT LIMIT

DEFAULT = 100 RANGE = OFF, 30 - 220 AMPS STEP = 10 A

This function is only used with the Link 2000-R (Alternator Regulator Model). It

setsasafetycurrentlimitforthealternator. Thislimitsthemaximumamountofcurrentthat

the alternator can ever deliver. This value is reset to 100Amps in the event of a reset to

factorydefaultvalues.

CAUTION: OFF defeats this safety feature and the alternator will be ran at

full output until the Acceptance Voltage is reached.

F11 - BATTERY #2 USED FOR CONTROL

DEFAULT ON = BATTERY #2 USED FOR CONTROL

OFF = BATTERY #2 IS NOT USED FOR CONTROL.

ThisfunctionisusedtodefeatBattery#2asapartofthechargercontrolfunctionof

Our Customer Service Manager says, "Be a genius, insure a

successful installation by following our wire by wire instructions

and please do the two progress and final start up tests."

BEGIN WITH THE MONITOR TERMINAL BOARD

Be sure the shunt is installed before proceeding.

The Monitor Terminal board should be secured behind or adjacent to the meter. It

should be accessible and easy to see during hook up. The meter comes standard with an

18" ribbon cable. Ribbon cables 48" long are available.

Wiringissimplifiedbyusingourcustommultipleconductortwistedpaircable

availablefromyourdealer. SeeLINK2000manual. If you supply your own cable we

recommend 16 AWG. Larger is OK but not necessary. Do not use larger than #14 AWG,

it will make terminating the wires difficult. Use twisted pairs where specified.

Begin hooking up from the bottom of the terminal strip toward the top.

Terminal #1 BLACK WIRE (AGND) is the Analog Ground. It is the reference for all

measurements. It must be connected on the BSHG (Grounded) side of the shunt. The

BSHGsideoftheshuntisthesideoppositeofthenegativebatteryterminals.Itmusthave

a good connection to one of the two #10 screws on the top of the battery shunt.

Terminal #2 is not used.

Thesetwocordsarenotinterchangeable.

Terminal #3LITE turns on the display backlighting. It may be supplied from a switch

thatcontrols other instrument lighting or itmaybe connected to Terminal #4 ifyouwish

the lighting to be on all the time. Set at the default lighting intensity the backlighting

consumesabout8mA(.008A). Ifleftonallthetimeitwoulduselessthan.2Ahrsperday.

Consider the options for the next wire.

Terminal #4 theRED WIRE (+12V) is the +12V supply. (In a 24V system supply with

+24V.) Thewiringdiagramshowstwooptions. Thepreferredoptionisto jumpertogether

terminals #4 and #5 as shown. Wired this way, the meter cannot accidentally be de-

powered. It has the disadvantage of always consuming a little bit of power from the #1

Battery. Themeterconsumesabout 28mA(.028A). Ifleftonallthetimeitwoulduseabout

0.7 A hrs per day.

Ifthesystemisleftonfor long periods, (long enough to significantly dischargethe

battery) with no charging sources, then you should consider the option shown with the

dotted line. In this case the RED wire is not jumped to the BLUE but supplied from the

commonof the battery switch. (Be sure toinstall the 2A fuseas near the batteryswitch as

possible.) Whichever battery is selected is the battery that supplies the power.

Caution:Withthisoptionifthebatteryswitchisturnedoffthemeterisde-powered

and resets to zero, therefore battery switch must never be turned off except when leaving

the system for a long period of time. When the system is returned to service you must

resynchronize the meter by fully charging the battery.

Another option for the red wire is to install a separate on/off switch in it before it

landsontheterminal board. Just remembertoturnoffthemeter when leaving thesystem

unattended.

PROGRESS CHECK #1

The wires hooked upso farallow youtocheck thevoltagemonitoring functions.

Install the fuse that supplies Terminal #4 and carefully plug the ribbon cable into the

Monitor Terminal board, make sure the pins are lined up correctly.

Fromnow onyou may de-powerthe meterbyunplugging theribbon cable.If

you remove the fuse that supplies terminal #4, +12V, with the ribbon cable plugged

in youmustbecarefulwhenreinstallingit. Itmustbeadeliberateaction. Ifthepower

to the meter is turned on and off in less than 5 second intervals it can cause the
