take the time to read these sections.

1) DO NOT DISCONNECT THE NEGATIVE BATTERY CABLE TO THE

FREEDOM WITH THE INVERTER OR CHARGER TURNED ON! WHEN

INSTALLING, CONNECT THE INVERTER CABLES BEFORE PLUGGING

THE REMOTE CABLE INTO THE LINK 2000. UNPLUG THE REMOTE

CABLE BEFORE THE FREEDOM INVERTER IS DISCONNECTED FROM

THE BATTERY.

2) Turn the ON/OFF switch located on the inverter to the OFF position.

3) When used in a mixed voltage (12 V and 24 V) system, Battery #1 is the battery that the

LINK2000usesforvoltageregulation.Makesureitisthebatterythatisusedbytheinverter/

charger, or with the alternator regulator option it must be the battery being charged by the

alternator. See Functions Mode F11 on page 13.

VOLTS

WhentheVOLTS switchispressed, thevoltageoftheselectedbatteryisdisplayed.

The measurement range is from 8.5 V to 50 V. The resolution is 0.05 volts. See page 39

for power supply specification.

AMPS

When the AMPS switch is pressed, the current flowing into or out of the selected

battery is displayed. Amps being consumed are displayed as a negative number. Charging

amps are displayed as a positive number (no sign). The resolution below 42 amps is 0.1

amps. Above 42 amps the resolution is 1 amp. The range is from -500 A to 500 A. Over-

range is indicated by OL.

consumed will decrease as the meter counts back up toward zero. The range is + 9,999Ah.

If the battery continues to be charged after the meter counts back up to zero,

overcharge amp hours are accumulated and displayed as a positive number. If there is an

accumulatedpositivenumberinthedisplaywhendischarging begins,themeterautomati-

cally resets to zero and begins counting down. See Overcharge Amp Hours on page 16.

The meter also automatically resets to zero after a discharge/charge cycle that

satisfies the conditions for a recalculation of the Charge Efficiency Factor (CEF). In other

words, if the battery is discharged 10% and then recharged until the charged parameters

have been met, the amp hours consumed display is reset to zero.

TIME

When the TIME switch is pressed, the time which the load can continue to be run

is displayed. The display is in hours with 0.1 hours resolution. The unit may be set up to

calculatethetimeremainingbasedontheinstantaneouscurrent, orarollingaverageofthe

last4,16,or32minutes.Thetimeremainingfunctionalsotakesintoaccountthemagnitude

of the discharge current (see pages 24–27). The maximum time remaining is 255 hours.

If you see this display, it means that the current being consumed could be supplied for

more than 255 hours. During charging, current is a positive (unsigned) number and the

Time remaining display reads C C C.

For the TIME function to operate correctly you must enter your BATTERY

CAPACITY through the SETUP routine (see page 9). You must also set up the correct

PEUKERT'S EXPONENT (see page 13). It is also affected by your selection of

DISCHARGE FLOOR (see page 14).

Caution: The TIME display is an estimate of how long your battery can sustain a

load. Wild variations in battery current, battery condition, erroneously declared battery

capacity, Peukert's exponent, temperature, or discharge floor, and prior charge and dis-

charge history may affect the accuracy of this estimate. Please use this display only as a

guide. The LINK 2000 provides you with several important battery parameters. Using

all of them, including voltage, current, amp hours consumed, and time remaining, allows

you to know about the state-of-charge of your battery. Do not rely on a single value to

determine battery status or performance.

STARTING AND STOPPING EQUALIZE

The Equalize Cycle conditions the battery with a controlled overcharge to remove

Lead Sulfate that is not removed during normal charging. Liquid batteries should be

Equalized every 30 days when in cycling service.

CAUTION! Turn off voltage sensitive DC loads before equalizing battery!

DC Voltage from the charger may go to 17 VDC (34 V for 24 V system) during

equalizing !

Charge batteries fully before equalizing. To start the Equalize Cycle, first be sure

that the Charger is ON, then press the SETUP BUTTON for five seconds until the LED

begins to flash. Now press both the VOLTS and the A hrs BUTTONS simultaneously.

Hold them both down for five seconds, until the Red CHARGE LED begins to flash,

and the "E" in the display goes away.

To terminate the Equalize Cycle and force the charger into the Float mode, repeat

the same procedure as above. The cycle automatically terminates after eight hours, or if

AC power is interrupted.

Equalizing causes the battery to gas. You should check your battery electrolyte

before and after equalization. Do not overfill before equalization as the electrolyte may

expand enough to cause it to flow over the tops. You should be present during this type

of charging. Make sure there is adequate ventilation. Leave the filler caps on or cover the

tops with a folded paper towel. Terminate the cycle if a battery starts to overflow or

overheat.

Gelled batteries are not normally equalized. However, if they have been severely

discharged, it may be the only way to get them to begin to accept a charge. The voltage

is limited to the Accept charging level but the cycle lasts for 8 hours. Be sure that the

battery TYPE # is set to #1 or #2 before using this cycle on gelled batteries (or #3 for

AGM type batteries).

Note: Equalizing voltages for Type #1, #2, and #3 batteries is limited to the

acceptance voltage for the respective battery type.

INVERTERSETUP

IDLE MODE: The default value is 4 watts. This means it takes a 4-watt AC load

to turn the inverter on from its low power idle mode. Setting a value of 0 watts means the

inverter is always on. The low power idle current is about 0.25 amps. When idle mode is

set to 0 W the current consumption goes up to about 0.9 amps. Range = 0 W, 4 W, 6 W,

15 W. (0–15 watts in 5-watt steps in Series 458 units.)

SETUP EXAMPLE: To set the IDLE MODE to 0 watts, first select the INVERT

on, then press the SETUP BUTTON until the Green LED begins to flash. Now, press and

hold the IDLE MODE BUTTON. The present value will appear. The display will scroll

afterthreeseconds.Holdthebuttondownuntil0appears.Releasethebutton.Thenewvalue

will remain in the display for about five seconds. When the display reverts to the normal

monitoringfunctionthenewvalueisstoredinnonvolatilememory. Toseeifthenewvalue

has been successfully stored, repeat the setup procedure but do not scroll to a new value.

PWR SHARE: The default value is 30 amps (or OFF for Freedom 25). The

power sharing feature automatically reduces the charger output, and therefore the AC

power consumption, if the load passing through the inverter's automatic transfer switch

exceeds the setup value. This load management feature helps prevent AC supply breakers

from tripping when boats or RVs are plugged into AC power and the charger, water

heater, and perhaps other loads all come on at once. In "Off Grid" applications the

auxiliary generator often has several jobs—water pumping, running the washing machine,

or heavy power tools—in addition to supplemental battery charging. With Power Sharing,

when a heavy load turns on, it reduces charger output to help supply the heavy load. The

ranges below are for units with serial numbers greater than 100,000:

Freedom 10, 15 & 20 Range = 5, 15, 20, 30 A; Freedom 25 & 30 Range = 5, 20, 30 A, OFF;

Freedom 10E & 20E Range = 2, 5, 10, 15 A; Freedom 25E Range = 2, 10, 15 A, OFF

For Freedom serial numbers below 100,000 use this table to interpret the display.

For Series 458 units, the range is 0–50 amps, settable in 5-amp steps.

ANOTHER SETUP EXAMPLE: To set PWR SHARE to 20 amps on a F10

Model with a serial number below 100,000, first select the CHARGE on, then press the

SETUP BUTTON until the green LED begins to flash. Now, press and hold the PWR

SHARE BUTTON. The present value will appear. The display will scroll after three

seconds. Hold the button down until 1 appears (see table above). Release the button. The

new value will remain in the display for about 5 seconds. When the display reverts to the

normal monitoring function the new value is stored in nonvolatile memory.

MONITORSETUP

Normally the only MONITOR SETUP parameter that must be changed is BATT

CAP (see bottom of this page). Please read the section on selecting charged parameters

(page 21–22) before changing CHARGED V or CHARGED % default values. (See

FUNC SETUP on page 10 for other system values that may need to be changed.)

Setting the following parameters only affects the operation of the monitor, mean-

ing that changing the Charged V parameter does not change the voltage set point of the

charger in the FREEDOM Inverter/Charger. It only sets the point at which the monitor

considers the battery full. To change the charging voltage during the Acceptance and

Float cycles use Ambient Temp. Setup routine. Note also that when the FREEDOM is

the charging source, the Charged % is always 2%.

SELECT BATTERY #1 OR #2: To set up a battery parameter, press the button

for the battery you wish to set up. The LED will light. Do this first as setup changes are

only made to the selected battery.

CHARGED V: The ability to set up a Charged Voltage above which the monitor

considers the battery full allows it to be used with any charging system or battery chem-

istry. The default Charged Voltage is 13.2 volts for 12-volt systems and 26.4 volts for 24-

volt systems. The LINK 2000 automatically selects the correct value based on the

voltage it senses. (If the Alternative Energy function F05 is ON, the default value is 13.5

volts or 27.0 volts. See FUNCTIONS SETUP, page 10, for details.)

To change CHARGED V follow the same procedure as described previously:

Select the battery to be set up. Press SETUP until the LED begins to flash. Then release

the button, and press CHARGED V until the desired voltage appears and then release

the button. The new charged voltage is stored in nonvolatile memory. If the charged

voltage is inappropriate for the sensed battery voltage, Error E14 is displayed (see Error

Codes and Troubleshooting, pages 28–29). Be sure to read the section on selecting

correct charged parameters (pages 21–22) before changing the charged voltage.

CHARGED %: The default value is 2%. This means that the charging current

(amps) flowing into the battery must fall below 2% of the declared battery capacity

before the meter considers the battery full. For example, using the default values of 2%

and 200 Ah means the current must fall below: 4 amps = 2% x 200 Ah.

Before changing the CHARGED % from either of these values, be absolutely

sure you understand the section on selecting charged parameters (page 21–22). Setup

and storage to nonvolatile memory is the same as for the function above.

BATT CAP: The default value is 200 Ah. The battery capacity must be set

up if it varies significantly (10–20%) from the default. The battery capacity is used in the

calculation to determine when the battery is full and in the TIME remaining function.

To change the battery capacity, press SETUP until the LED begins to flash, then

release the button. Now press BATT CAP. Scroll until the desired battery capacity is in

the display. If you are unsure of your battery capacity you may first test it as described

on page 17. The battery capacity is stored in nonvolatile memory. If you change to a

different capacity battery you must change this number. Range = 20–2000 Ah in 20 Ah

increments.

FUNCTIONS SETUP

FUNC: The FUNC (Function) mode is used to set up

special functions or features that are not commonly

changed. They might be thought of as internal software

switches that allow the selection of special functions,

or values that, once set, are seldom changed.

Normally the only functions that must be changed

are F02 Battery Type, F03 Ambient Battery Tempera-

ture, and F08 Peukert's Exponent. (See page 9 for how

to set battery capacity.)

The setup process for functions is slightly different because the FUNC button is

used first to scroll to the function to be set up, and then to scroll through the values for

that function. To access the FUNC mode:

1) Press and hold the SETUP button until the green LED begins to slowly flash, then

release the button.

2) Now press the (blue) FUNC button. The letters ꢀ01 will appear in the display and

the FUNC LED will begin flashing, indicating you are in the FUNC mode.

3) Scroll to the function to be set up by holding down the FUNC button.

4) Release the FUNC button and wait for the current value of the function you have

selected to appear in the display. This will take about three seconds.

5) Press the FUNC button now and the display will scroll through the range of values.

Stop scrolling when the value you wish appears in the display.

6) If you wish to continue to set up other functions, press the SETUP button until the

green LED by the FUNC button stops flashing. You may now choose any blue key to

continue setting up the LINK 2000. If you press the FUNC button again the process

will begin at the next function after the one you last set up. Whatever functions you have

set up will become active when the display reverts to its normal mode.

FUNCTIONS TABLE

F01 - AVERAGE PERIOD FOR TIME REMAINING CALCULATION

0 = INSTANTANEOUS (DEFAULT)

1 = 4-MINUTE AVERAGE

2 = 16-MINUTE AVERAGE

3 = 32-MINUTE AVERAGE

There are four averaging periods that the LINK 2000 can use to calculate the time

of operation remaining. You may select present consumption level (instantaneous), a

four-minute rolling average, a 16-minute, or a 32-minute rolling average. Which method is

best for you depends on your installation. Most installations will find the instantaneous

or the four-minute average appropriate.

Operating Tip: Use the longest period of time you can to ensure long term load

variations are considered. If you want instant feedback, use the instantaneous display

(no averaging) "0" display.

F02 - BATTERY TYPE

0 = LIQUID CELL (DEFAULT)

2 = GEL CELL (FAST CHARGE)

1 = GEL CELL (STANDARD)

3 = AGM (Absorbed Glass Mat)

This function (Default: Type 0, standard liquid cells) sets the appropriate charge

and float voltages for the FREEDOM charger (see table below) and sets an appropriate

Peukert exponent. Gel cell owners may use Type 1 or Type 2, but should consult with

the battery manufacturer prior to using the more aggressive charging regimen described

by Type 2. Type 3 sets Acceptance and Float voltages suited to AGM type batteries.

F03 - VIEW OR SET AMBIENT BATTERY TEMPERATURE

THIS FUNCTION DEPENDS ON THE SETTING OF F14 (SEE PAGE 14

)

IF F14 IS ON, F03 VIEWS THE PRESENT BATTERY TEMP. (°F)

If F14 is ON, charging voltage of the Freedom charger and the Ideal Regulator (if

using a Link 2000-R) is based on the TEMPERATURE COMPENSATION TABLE

below. The temperature is displayed until another button is pressed on the Link.

IF F14 IS OFF, F03 SETS A DECLARED BATTERY TEMP. (°F)

DEFAULT = 70 °F

RANGE = 30–120 °F

STEP = 10 °F

The default value for ambient temperature is 70 °F. The ambient temperature of the

battery may be set up to select the appropriate Charge and Float Voltages for the charger.

The temperature may be selected in 10 °F increments. The setup procedure is the same

as previously described.

Setting up a different value should only be done if the battery is at a temperature

significantly different from 70 °F when they are being charged from the FREEDOM.

If the batteries are located in a hot engine room, but are not normally charged from the

FREEDOM when the engine is running, do not adjust the temperature to the engine

room level. High temperatures are destructive to batteries. If your batteries are regularly

subjected to temperatures above 100 °F you should relocate them or supply forced fresh

air ventilation.

Caution! Do not adjust to extremes unless the battery is normally at that

temperature. Destructive over- or under-charging may occur. Multiply values by

2 for 24-volt systems. Voltages are typical, charger regulation + 0.2 volts DC.

Turn this mode on if your Link 2000 is used in Alternative Energy Systems.

This function 1) reduces the time necessary to satisfy the charged parameters from five

minutes to one minute; 2) sets Batt #2 discharge floor to 100%; 3) prevents Batt #2 from

doing Ah resets; 4) changes Charged V parameter to 13.5 V (27 V). If you're using a semi-

F08 - SET PEUKERT'S EXPONENT

DEFAULT = 1.25 RANGE = 1.00–1.50

STEP = 0.01

Sets the exponent for Peukert’s equation. A setting of 1.00 defeats Peukert's

calculation. See pages 24–27 for a discussion of Peukert's equation and typical values for

various batteries. Properly setting Peukert's exponent ensures a more accurate display of

timeremainingandpercentremaining.

F09 - Ah OR RATE COMPENSATED % REMAINING MODE

DEFAULT OFF = Ah DISPLAY MODE

ON = RATE COMPENSATED PERCENT REMAINING MODE

Changes the A hrs function to % Remaining mode, which displays the selected

battery's rate compensated state-of-charge as a percentage of the declared capacity. A full

battery is displayed as P100 and a 50% charged battery is displayed as P050. When in

this mode, the battery capacity and Peukert exponent must be accurately set up.

This option is not available when F04 or F05 is ON.

F10 - ALTERNATOR CURRENT LIMIT

DEFAULT = 100

RANGE = 30–220 AMPS, OFF

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

sets a safety current limit for the alternator. This limits the maximum amount of current

thatthealternatorcaneverdeliverwhichinturnreducesheatandwearonbeltsandbearings.

The OFF position turns alternator current limiting off.

F11 - BATTERY #2 USED FOR CONTROL

DEFAULT ON = BATTERY #2 USED FOR CONTROL

OFF = BATTERY #2 IS NOT USED FOR CONTROL

This function is used to defeat Battery #2 as a part of the charger control function

oftheFREEDOM inverter(alsoalternatorcontrolintheLink2000-R). Thisisnecessary

for systems that have both 12 V and 24 V batteries. Battery #1 must be the battery that is

used by the FREEDOM. You may also wish to use this function if the main house battery

(Bank1)issubstantiallylargerthanaseparateenginebattery(Bank2)thatisalsomonitored

by the LINK 2000. This will prevent the LINK 2000 from making a premature transition

to float based on the smaller engine battery meeting the charged parameters substantially

before the house battery.

NOTE: This function is not changed in a reset to factory default values. If you

wish to change this function you must use the setup routine to change it.

HOW TO USE THE LINK

BATTERY MANAGEMENT PHILOSOPHY:

Recharge When the Battery is 50% Discharged!

The LINK 2000 is a guide to the battery's state of charge. Our Mid-Capacity Rule

asadesignandoperatingguidelinetoprovideoptimalbatterylifeandensurethemostenergy

output from the battery over its life, not a law which must be obeyed without exception.

We recommend synchronizing your LINK 2000 to the 100% charged level of the

battery. You should begin recharging when 50% of your battery capacity has been

consumed. When recharging from an engine-driven alternator or generator

suppliedbatterychargeryoudonothavetochargeuntilthemeterreads0amphours

consumed. You may cease charging when the LINK 2000 is displaying that 15% of the

battery capacity is still consumed. See the example below. When you plug back into AC

power, or when your Alternative Energy production exceeds demand, the remaining amp

hours consumed will be replaced.

MANAGINGATWO-BATTERYSYSTEM

With a two-batterysystemwerecommendusing battery#1untilyou consume50%

of its capacity, then switch to battery #2 and use 50% of it. When both batteries are 50%

discharged it is time to charge. You should never leave either battery partially discharged

for more than a few days.

Suppose you have two 200 Ah batteries for a total system capacity of 400 Ah and

youhavesynchronized yourLINK2000to 100%chargedbatteries.Youwouldusebattery

#1 until the LINK 2000 showed that you had used 50% (the display would show -100Ah).

You would then use battery #2 until you had used 50% of it (-100Ah). At this point charge

both batteries up to about the 85% level (-30 Ah on each). If you have other reasons to

continue running the engine or plug back into AC power you may continue charging until

the meter reads zero.

OVERCHARGE AMP HOURS

If the battery is 100% charged, and the LINK 2000 is in sync with the batteries,

overcharge amp hours are displayed as positive. Some accumulation of overcharge amp

hours is normal and harmless with systems continuously connected to a charger. For

example: a 100 Ah battery at the Float voltage will normally have less than 0.1 A flowing

intoit.Thismeansthatamaximumof 2.4Ahofoverchargewouldaccumulateina24hour

of amp hours each day. This is a clear indication that you are destroying your battery by

overcharging.CheckyourLINK2000beforeturning offachargingsourcetoseethatyou

have not accumulated too many overcharge amp hours. When discharging begins,

overcharge amp hours are erased and the LINK 2000 resets to zero.

Systems that have a Conditioning or Equalization cycle will accumulate a few

overchargeamphoursduring equalization.ThisisnormalandensuresthattheLINK2000

stays in sync with the battery state of charge.

BATTERYCAPACITYTESTING

Your LINK 2000 can be used to conduct periodic capacity tests that tell you the

actualamountofenergyyour batteriescanstore.Acapacitytestshouldstartwithabattery

that has been properly charged and conditioned. The objective is to find the maximum

availablecapacity.

Deep-cycle battery capacity is usually based on a 20-hour discharge rate. A 100 Ah

battery will provide 5 amps for 20 hours. At discharge rates above 5 amps, the battery will

not supply 100 Ah. For example: If you are drawing 100 amps out of the battery it will last

less than one half hour. This was discovered in 1897 by a scientist named Peukert and is

discussed in detail later. You can see the effect in the following table listing approximate

capacities at different discharge rates.

passed before the battery voltage fell to 10.5 V you can still determine the capacity with

somearithmetic. Forexample:assumea12Vbatteryratedat100Ah. Applya5-ampload.

Suppose it only took 10 hours for the voltage to reach 10.5 volts. The LINK 2000 would

display -50 Ah. This is the 10-hour capacity. Dividing 50 by 89% (10-hour rate) from the

table above, you determine that the actual 20-hour capacity is 56 amp hours. You could

repeat the test at 5% of the tested capacity (2.8A) to verify the actual capacity.

run until the inverter shuts down on low voltage (about 10.2 V). Read the number of amp

hours that have been consumed from the battery. If it is not close to the expected number,

use the procedure outlined above to estimate the capacity.

Caution! Be sure to completely recharge your battery after a discharge test.

IDEALCHARGECURVE

The LINK 2000 transmits critical battery state of charge information to the

FREEDOM Inverter/Charger. This enables the charger to conform to our proven Ideal

Charge Curve with four basic cycles: Charge, Accept, Float, and Equalize. The

CHARGE cycle supplies full charger output current until the battery reaches the Accept

charging voltage (14.4 V typically). The ACCEPT cycle continues until the battery is

acceptingonly asmallamountofcurrent.Thebatteryisnowfull.DuringtheFLOATcycle

the voltage is lowered to maintain the batteries, without water consumption, for long life.

TheEQUALIZEcycleallowsforperiodic"equalization"ofliquidelectrolytebatteriesfor

maximum capacity and life. The batteries should be equalized about every 30 days during

deep-cycling service.

HOW TO TELL WHEN A BATTERY IS

FULLY CHARGED

(CHARGED BATTERY PARAMETERS)

MULTIPLE STAGE CHARGING SYSTEMS

If youareusingthechargerintheFREEDOM,thebatteryischargedwhenthesystem

switches to the Float cycle. If another manufacturer's charging system is being used it

should be adjusted so the transition from Acceptance Charging to Float will occur when

thechargingcurrent,attheAcceptanceVoltage(14.4/28.8Vtypically),dropstobelow2%

ofthebatterycapacity.(SeethedescriptionoftheIdealChargeCurveonthepreviouspage.)

CONSTANTVOLTAGECHARGINGSYSTEMS

Constantvoltagechargingsystemshaverestoredas muchchargetoabatteryas they

can when the voltage reaches the maximum regulation point (a typical 12 V system is set

at 13.8 V) and the charging current drops to less than 1% of the battery capacity. (It can

take more than eight hours for a battery to reach this state of charge.) If you are using an

engine-drivenchargingsystemandtryingtolimitengineruntime,youprobablywillcharge

only until the current drops to 5% or 10% of capacity. The LINK 2000 should be

synchronized to whichever of these charge levels is reached in normal operation.

USINGSPECIFICGRAVITY

Accurate battery current measurement is necessary to determine the charged

parameters in the two previous methods. Specific gravity of the battery can also be used

todetermine thechargelevelofabattery.Regardlessofthechargingsystemused,a battery

is charged when the specific gravity shows no increase for three hours, when measured at

half hour intervals. Typical specific gravity @ 77 °F for a fully charged liquid electrolyte

battery is 1.265 + 0.050.

CHARGE EFFICIENCY FACTOR (CEF)

AND HOW IT IS USED

The CEF determines the rate at which the Link 2000 counts back up during charging

to compensate for the inefficiencies of the charging process. The CEF has a factory

default value of 87%. That means the charger must return 1.15 Ah to the system for the

battery to restore 1.0 Ah.

The CEF is automatically recalculated (and averaged over the last few cycles) after

every charge cycle if the battery has been discharged more than 10% of the declared

battery capacity and the charged parameters for voltage and current (selected automati-

cally or manually in the setup procedure) are met for five minutes (may vary by setup).

Additionally, 100% of the kWh removed must be returned during charging.

Continual CEF compensation ensures that the battery state of charge and the Link

2000 stay in sync. Monitoring the CEF over time helps assess changes in performance of

the battery or charging system.

SYNCHRONIZINGYOURLINK2000

TO A CHARGED BATTERY

A charged battery has zero Ahrs removed. Synchronizing your LINK 2000 to read

zerowhenthebatteryischargedensuresthatyoualwaysknowthenetnumberofamphours

removed. The charged parameters on the previous page indicate when a charging system

has put as much energy into a battery as it normally can and the battery can be considered

charged.

Your LINK 2000 must be synchronized at this point!

TWO WAYS TO SYNCHRONIZE

There are two ways to synchronize your LINK 2000 to a battery that has met the

charged parameters:

1) Install the LINK 2000 on a charged battery and it will automatically be in sync.

2) If the LINK 2000 is installed on a partially charged battery, simply charge until

the charged parameters are met. The LINK 2000 will begin counting up and will display

chargingamphoursaspositive.When the battery ischarged,turnoffthechargingsource.

AfterdischargingbeginstheLINK2000automaticallyresetstozero,startscountingdown,

and is in sync.

If the LINK 2000 should ever get out of sync with the battery state of charge

it must be re-synchronized. The best way to do this is to be sure the battery is

discharged at least 10% of the declared battery capacity and then recharge until

the charged parameters are met. At this point the meter should automatically reset

to zero.

Remember, a battery should be fully charged, and float charged if possible, when

leaving it for extended periods of time for best battery life. This will automatically ensure

that the Link 2000 stays in sync. Some things that will cause the Link 2000 to not stay in

syncare:1)dischargecycleislessthan10%ofbatterycapacity,2)batterynotfullycharged

to 100%, 3) charged voltage set too high for the charging system, 4) charged current % of

for 100% charge.

MANUALLY RESETTING AMP HOURS TO ZERO

If you want to manually reset your LINK 2000 amp hours display to zero:

1) First select the battery you wish to reset.

2) Press the SETUP button for five seconds. When the LED begins flashing,

release the button.

3) Press and hold the RESET A hrs button for three seconds (until the normal

display returns) to reset the amp hours of the selected battery to zero.

MANUALLYSELECTINGTHECHARGED

BATTERYPARAMETERS

DISCUSSION: HOW THE LINK 2000 USES THESE VALUES

The LINK 2000 allows the setup of specific charged parameters. The factory

default values have been carefully chosen to work on most systems, including constant

voltageandmultiplestepchargingsystems.ThefactoryChargedParametersare 13.2volts

and 4 amps (2% of the default battery capacity of 200 Ah). This means when the battery

is above 13.2 volts and the current falls below 4 amps, for five minutes, the LINK

2000 considers the battery full.

The LINK 2000 learns the Charge Efficiency Factor (CEF) of the battery based on

the Charged Parameters. A CEF of greater than 100% is not allowed. To trigger a

recalculation of the CEF, the battery must be discharged at least 10% of declared capacity.

Afterthisdischarge,atleast100%oftheenergy(kWh)removedmustbereturned,andboth

the Charged Voltage and Charged Current % parameters must be met for five minutes for

a recalculation of the CEF to occur. Amp hours consumed are automatically reset to

zero after a recalculation of the CEF. The new CEF is used during the next recharge

cycle to determine the rate that the meter counts back up toward zero.

The battery must go through several cycles for the meter to learn the CEF.

It will take several (at least six) cycles for the displayed CEF to reflect the actual CEF of

the battery.

SHOULD YOU CHANGE THE CHARGED PARAMETERS?

Pleaseconsiderchangingonlythebatterycapacityunlessyoursystemfallsintoone

of the following categories:

1) Battery chemistry other than lead acid.

If you are using NiCad or other types of batteries you should change your Charged

Parameters to the factory specification. NiCad systems would normally use 15.5 to 15.7

astheChargedVoltage.TheChargedCurrent%canprobablystayat2%ofdeclaredbattery

capacity.

2) Charging normally ends before the current drops below 2% of battery capacity.

If the charging system is shut down before the charging current drops below 2%,

thefactoryChargedCurrent%willhavetobechanged.Examplesmightincludelargesolar

arrays with controllers that shut off the array at a particular voltage and turn it back on at

RULES FOR CHANGING THE

CHARGEDBATTERYPARAMETERS

If you must change the Charged Parameters please use the following rules.

1) The Charged Voltage MUST be at least 0.1 V BELOW the charging system

voltage.

2) The Charged Current % times declared Battery Capacity MUST be

GREATER than the minimum current the charging system maintains the battery at, or

turns off at.

If the charged parameters are not correctly selected,

the LINK 2000 will never recalculate the CEF. For example:

(1) Ifyourchargingsystemonlyreaches13.8(27.6)volts,aChargedVoltageof14.0(28.0)

volts will not work—it is set too high and the Link 2000 will never know that the battery

ischarged.LowertheChargedVoltage.ChangingtheChargedVoltageto13.7(27.5)volts

should work. See Monitor Setup on page 9.

(2) If the Charged Current % times the Battery Capacity is less than the current at which

the charging system switches off, the Charged Current cannot be met and the Link 2000

willneverknowthatthebatteryischarged.Ifthechargingsystemshutsoffwhenthecurrent

is 10 amps, using the factory default value of 4 amps (2% of 200 Ah) will not work.

(Changing the Charged Current % to 6% would give a Charger Current of 12 amps, which

would work fine. See Monitor Setup on page 9.)

Ifyouhaveachargingsystemthatcannotsatisfythedefaultvalues,theCEFwillnot

be recalculated and the meter will use the default CEF of 87%. This will work fine in most

systems. You may notice an accumulation of negative amp hours. If so, set up appropriate

chargedparametersorresynchronizeperiodically.(SeeSynchronizingYourLink2000To

a Charged Battery on page 20.)

HIGH DISCHARGE RATES

& PEUKERT'S EQUATION

Peukert's Equation describes the effect of different discharge rates on battery

capacity. As the discharge rate increases the available battery capacity decreases. The

tables on pages 25, 26 and 27 have typical values of "n" for common batteries. Page 25

is a look-up table, pages 26 & 27 have "n" values for common batteries, and page 27 has

the formula for calculating "n" for other batteries.

The LINK 2000 uses Peukert's equation only for calculating the Time Remaining

of operation function. The amp hours display is always the actual number of amp hours

consumed. This means that if you rapidly discharge a battery, your time remaining

number may show zero hours remaining before you see the total number of amp hours

of battery capacity consumed.

If battery Type 0 is selected, the initial Peukert exponent is set at 1.25. This

is an appropriate mid-range value for many common liquid cells. If any other battery

type is selected, the initial Peukert exponent is set at 1.11. This is an appropriate

mid-range value for many common gel and AGM cells. Please note that you may only

declare one battery type using function F02. This is because we strongly recommend

against mixing AGM, gel, and liquid electrolyte batteries in the same system. The

selected Peukert exponent is applied to both battery banks. Set the exponent to the

correct value for the bank which you use most often.

Making two discharge tests, one at a high discharge rate and one at a low rate, that

bracket your normal range of operation allows you to calculate an "n" that will describe

this varying effect. The Link 2000 uses a default value of "n" equal to 1.25 which is

typical for many batteries.

At some low-to-moderate discharge rate, typically a battery's 20-hour rate, the

logarithmic effect of Peukert's Equation is greatly reduced. The effect of discharge rates

smaller than this is nearly linear. Battery manufacturer specifications of battery capacity

in amp hours is typically given at the 20-hour rate. From this description, if a battery is

discharged at this rate for the period of time called out, you will be able to remove the

rated capacity.

The equation for Peukert's Capacity (C ) is:

log t₂- log t₁

n =

C = I t where

log I₁- log I₂

By doing two discharge tests and knowing I₁& I₂(discharge current in amps of

the two tests), and t₁& t₂(time in hours for the two tests) you can calculate n (the

Peukert exponent). You will need a calculator that has a Log function to solve the equation

above. You may also use the 20-hour discharge rate and the number of reserve minutes

as the two discharges to solve Peukert's equation. See example on page 27. After you

solve for your Peukert's exponent you may enter it using Function F08.

CALCULATING PEUKERT'S EXPONENT

Example of using Reserve Minutes @ 25 amps

and the 20-hour rate to calculate "n".

First convert Reserve Minutes to hours, then find the discharge current

at the 20-hour rating. Finally use a calculator to solve the arithmetic.

Trojan T-105:

Reserve Minutes = 447 min @ 25 amps.

t₁= 447 min = 447/60 = 7.45 hrs

I₁= 25 amps

20-Hour rating = 225 Ah

t₂= 20 hours

I₂= 225 amp hours/20 hours = 11.25 amps

log t₂- log t₁

log 20 - log 7.45

log 25 - log 11.25

MICROPROCESSOR RESET PROCEDURE

The LINK 2000 uses a microprocessor to perform all of its calculations and

functions. We have worked very hard to ensure a stable, trouble-free product. However,

likeallcomputerproducts,theunitissometimessusceptibletopowersupplydipsorsurges

that can cause erratic behavior or memory errors. If you detect a problem, please use the

following procedure to reset the microprocessor—you may also need to reset the memory

tothefactorydefaultsasdescribedonthe next page. If you reset to factory defaults besure

and set up appropriate values for battery capacity, battery type, ambient temperature, and

Peukert's exponent as previously described. Please read the entire instruction set before

beginning the procedure.

TO RESET FROM A LOCKUP, ERRATIC DISPLAY, OR ERRATIC BEHAVIOR

REQUIREDREADING

Before wiring the LINK 2000, install the shunt as indicated.

All wiring should be done before installing the fuses.

GENERALNOTES

1) Wiring to the LINK 2000 should be #16 or #18 AWG. (Larger wire is acceptable, but

not necessary.) Wiring should be per NEC or applicable standards.

2) The Shunt Sense Leads should be a twisted pair. Leads up to 1,000 feet long may be

used if they are not run along with other noise-producing conductors. Offset error should

be less than 0.2 amps.

Fortheeasiestinstallationyoumaywishtopurchaseourfourtwistedpaircablewith

thesamecolorcodeasthemeter.Thiscablemayberunbetweenthemeterandthebatteries

to supply all needed signals. This cable is available from your dealer or from Xantrex.

Note: You may make your own twisted pair wire by chucking up two wires in an electric

drill motor and twisting them by running the drill motor until there is a twist every inch. A

wrap of tape every 16" will keep the wires together and make them easier to pull through

the raceway.

3) Caution! If your starter draws more than 500 amps see #5 below.

CAUTION!!!!

The output voltage of the shunt is very small. It is critical that all of the

connections for the shunt sense leads have the highest possible integrity. Every

effort must be made to prevent corrosion that might affect the sense leads.

4) Battery current is sensed with a shunt, which is a very precise, small resistance. It is

insertedinseries(in line)inthenegativewireofthecircuityou wishtomeasure.The current

is measured by sensing the voltage drop across this resistance. The LINK 2000 uses

a 50 mV, 500-amp shunt. When 500 amps flows through the shunt, there is a 50 mV drop

across it. Thus 10 amps equals 1 mV or 1 amp equals 0.1 mV. The display is scaled to read

amps. If you wish to check this you will need a very accurate digital meter (Fluke 87 in

4 1/2 digit mode or better) if the current is below 30 amps (3.0 mV). Above 50 amps most

digital meters can be used for testing.

5) Note for Marine and RV installations: If starter current exceeds 500 amps, the starter

negative must be connected to the battery side of the battery shunt so that starter current

does not flow through it. The problem with this is that if the alternator is of the grounded

case type its current will not be flowing through the shunt. The alternator ground must be

isolatedfromtheengineandruntothe loadsideofthebattery shunt to beable tomeasure

the current going into the battery from the alternator. Isolated negative output alternators

areavailableandwestronglyrecommendthem. Withisolatednegativeoutputalternators,

rememberthatinstrumentation andotherloads groundeddirectlyto theengine blockwill

not be measured unless their negatives are relocated to the load side of the Battery Shunt.

Special high current shunts are also a solution and may be ordered from us. A separate

engine starting battery whose negative is connected directly to the engine also solves the

problem.

6) Wehaveshownseveralwiresconnectedtotheloadsideofthebatteryshuntinthewiring

diagram. If more than a few wires must be connected here, it is best to use a 2/0 jumper

from the shunt to a good negative bus. We recommend that no more than two, or at a

maximum three, connections per large bolt be made on the negative bus side of the shunt.

The negative bus should be a solid copper or brass bar with many threaded screws under

which the negatives for all of the loads may be secured. It should be fed with a conductor

of sufficient size so that there is no appreciable voltage drop even under full load.

WIREBYWIREINSTALLATION

Be sure the shunt is installed before proceeding.

The BLACK WIRE (AGND) is the Analog Ground. It is the reference for all measure-

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

of the shunt is the side opposite of the negative battery terminals. It must have a good

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

The RED WIRE (+12 V) is the +12 V supply. (In a 24 V system supply with +24 V.) The

wiringdiagramshowstwooptions.ThepreferredoptionistojumpertogethertheREDand

BLUE wires as shown. Wired this way, the meter cannot accidentally be de-powered. It

hasthedisadvantageofalwaysconsumingalittlebitofpowerfromthe#1Battery.Themeter

consumes about 28 mA (.028 A). If left on all the time it would use about 0.7 Ah per day.

If the system is left on for long periods (long enough to significantly discharge the

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

common of the battery switch. (Be sure to install the 2 A fuse as near the battery switch

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

theRED wireifyouwishthelightingtobeonallthetime.Thebacklightingconsumesabout

8 mA (.008 A). If left on all the time it would use less than 0.2 Ah per day.

directly from Battery #2. Be sure to install the 2-amp fuse shown in the drawing.

NOTE: If only one battery is to be monitored, connect the VIOLET wire to

the BLUE wire.

The GREEN WIRE (B1SHG) is connected to the SMALL SCREW ON THE GROUND

SIDE, OR LOAD SIDE, of the battery #1 shunt (B1SHG). This wire must be located

exactly as described to ensure accuracy of current measurements. The wires that run

from the battery #1 shunt sense terminals to the GREEN AND ORANGE wires should

be a twisted pair.

The ORANGE WIRE (B1SHB) is connected to the SMALL SCREW ON THE

BATTERY SIDE of the battery #1 shunt (B1SHB). This wire should be located exactly

as described to ensure accuracy in current measurements.

NOTE: If only one current input is used, connect the Green and Brown wires

THE INVERTER REMOTE CABLE

The only connection between the Freedom and the Link Control Panel is a standard

remotecable.Therearethreejacksontheback(bottom)oftheinverter.Usetheonelabeled

REMOTE. It is best to plug the remote cable into the LINK 2000 after it is powered up.

It is supplied with a 25' cable. You may purchase longer cords from any telephone supply

company. You should limit its length to 50 feet. Do not run the remote cable in the same

wireway as very noisy power conductors. This helps reduce noise interference problems.
