AND LINK 2000-R METERS WITH SERIAL NUMBER ABOVE 5000

INTRODUCTION AND SPECIAL NOTES

The LINK 2000 is an integrated battery monitor and inverter/charger control. It displays
the critical information necessary for 12 V or 24 VDC system battery management and
allows precise control of critical inverter and charger features. The Link 2000-R comes with
an additional manual describing the Ideal Regulator option. The LINK 2000 may be used
as a stand-alone battery monitor or with the following inverter/chargers:

FREEDOM 10, 15, 20, 25, and 30
In order to understand, use, and install the LINK 2000, PLEASE read this manual! It
is as short as possible and provides important information. For installation, operation,
or warranty questions, please call Xantrex.

The following Important Special Notes contain cautions and special considerations that
must be considered during the installation of the LINK 2000. Failure to read and follow these
special notes can lead to damage of the LINK 2000, the inverter, or other electrical equipment.

The Helping Hand is used to draw your attention to very important sections of this

manual or to indicate items that may need to be changed through the SETUP routine. Please
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
THE REMOTE CABLE INTO THE LINK 2000. UNPLUG THE REMOTE
CABLE BEFORE THE FREEDOM INVERTER IS DISCONNECTED FROM
THE BATTERY.

BEFORE PLUGGING

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
LINK 2000 uses for voltage regulation. Make sure it is the battery that is used by the inverter/
charger, or with the alternator regulator option it must be the battery being charged by the
alternator. See Functions Mode F11 on page 13.

BASIC BATTERY FACTS

1) One amp-hour (Ah) is 1 amp for one hour, or 2 amps for 1/2 hour, or 4 amps for 1/4 hour, an d
so on.

2) A liquid battery is generally considered completely discharged when the battery voltage
reaches 10.5 volts for a 12 volt battery.

3) Batteries for cycling service are normally rated with a) a 20-hour discharge rate which
means, for example, a 100 Ah battery will sustain 5 amps for 20 hours, and b) a reserve
capacity stated in minutes for a 25-amp discharge rate.

4) Our Mid-Capacity Rule says that discharge below 50% shortens battery life and charging
more than 85% takes too long with an engine-driven charging system. So, 35% of the battery
capacity is all that is normally available.

MONITOR FUNCTIONS

Please also refer to the one-page summary of features in center of this manual.

The small blue legends indicate Setup functions described later.

BATTERY SELECT

The battery to be monitored is
selected by pressing the #1 or
#2 switch. A Green LED indi­cates which battery is selected.
("Battery" may be a "bank" of
batteries.)

VOLTS

When the VOLTS switch is pressed, the voltage of the selected battery is displayed.
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. Over­range is indicated by OL.

Ahrs

When the A hrs switch is pressed, the amp hours (Ah) consumed from the battery
is displayed as a negative number. During discharge the negative number will grow as amp
hours are consumed and the meter counts down. During charging, the number of amp hours
consumed will decrease as the meter counts back up toward zero. The range is

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
accumulated positive number in the display when discharging begins, the meter automati­cally 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.

+ 9,999Ah.

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
calculate the time remaining based on the instantaneous current, or a rolling average of the
last 4, 16, or 32 minutes. The time remaining function also takes into account the magnitude
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

4

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 dis­charge 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.

LO BAT

When 50% of the declared capacity of either Battery #1 or #2 is consumed, LO BAT
flashes in the upper left hand corner of the display. (This indicator is affected by both the
declared battery capacity and the discharge floor setting.)

INVERTER/CHARGER FUNCTIONS

INVERT

When the INVERT switch is pressed, the inverter is
enabled and the Green LED is lit. The inverter will only provide
output if it is hooked up to the battery and there is no external
AC power available. The inverter ON indicator does not
indicate actual operation, only that the inverter is enabled. The
initial power-up condition is with the inverter turned OFF.

CHARGE

When the CHARGE switch is pressed, the charging
function of the Freedom Inverter/Charger is enabled. The
Green LED is lit when the charger is enabled. The initial power­up condition is with the charger enabled. The charger will only
provide output if it is hooked up to a battery and an external
source of AC power is present (shorepower or generator).

MARINE AND RV OPERATING TIP

When utility power is available, any loads normally supplied by the inverter are
automatically transferred to utility power through the internal transfer switch. When utility
power is not available the loads run on stored energy in the battery. If you have a load such
as an electric space heater running on a circuit that is automatically transferred, you run the
risk of deeply discharging your battery if there is a utility blackout. To avoid this, turn the
inverter function OFF when leaving the boat or RV unattended. Leaving the charger function
ON will ensure a full battery when you return.

5

STATUS LINE

There are four LED status indicators to show the presence of AC power and the charger's
cycle state.

AC IN: Green LED on when AC is present.
CHARGE: Red LED on when charger is in 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.

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.
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.

SETUP

I4.35I4.35

I4.35

I4.35I4.35

The LINK 2000 has been set up with default values chosen to work with a typical

system. Normally the only values that must be changed are:

1) Battery capacity (page 9) 3) Battery type (liquid or gel) (F02 page 11).

2) Ambient Temperature (F03 page 11) 4) Peukert's exponent (F08 page 13).

The SETUP BUTTON is used to access the functions in small blue text below each
button's primary function. It is also used for certain advanced functions described later.
To set up a value or function:

1) Select the battery to be set up by pressing Battery #1 or #2, (or Invert, or Charge, when
setting up Idle Mode or Pwr Share).

2) Hold down the SETUP BUTTON until the green LED flashes at one-second intervals.

3) Release the SETUP BUTTON and press and hold the function to be set up. The LED
of the function being set up will also begin to flash at one-second intervals. The present value
of the function will appear in the display.

4) After three seconds, with the button pressed, the display will begin scrolling. When the
desired value appears, release the button. If you continue to hold down the button, the
display will increment to the end of its range, roll over to its minimum value, and continue
to scroll. You may also "bump" a value by repeatedly pressing the button.

You may set up additional values, or functions, as long as the SETUP LED continues
to flash. When the SETUP LED stops flashing, all values that were changed during the setup
routine will be stored in nonvolatile memory.

INVERTER SETUP

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
after three seconds. Hold the button down until 0 appears. Release the button. The new value
will remain in the display for about five seconds. When the display reverts to the normal
monitoring function the new value is stored in nonvolatile memory. To see if the new value
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.

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.

MONITOR SETUP

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

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

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%.

only made to the selected battery.

considers the battery full allows it to be used with any charging system or battery chem­istry. The default Charged Voltage is 13.2 volts for 12-volt systems and 26.4 volts for 24­volt 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.)

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 Tempera­ture, 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
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
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.

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) 1 = GEL CELL (STANDARD)
2 = GEL CELL (FAST CHARGE) 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

F04 - TOGGLE DISPLAY BETWEEN AHR AND KWHR

DEFAULT OFF = Ah DISPLAY MODE
ON = Ah/kWh ALTERNATING DISPLAY MODE

When this function is selected the A hrs display alternates between the normal amp-
hour mode and the kilowatt-hour counter that the LINK 2000 uses to determine if 100%
of the energy consumed from the battery has been returned. A recalculation of the CEF is
not permitted unless this counter is greater than 0.00 kWh. This counter counts down during
discharge and the kilowatt hours consumed are displayed with a negative number. During
charging it counts back up with 100% efficiency. Not allowing a recalculation of the CEF
and an Ah reset until a positive number is in the counter ensures that there will not be
a premature reset. See page 21 for conditions required for a recalculation of the CEF and
an Ah reset.

F05 - ALTERNATIVE ENERGY MODE

DEFAULT: OFF

ON = USE ALTERNATIVE ENERGY DEFAULTS

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 semi­mechanical photovoltaic controller, we strongly suggest you also consider changing

Charged Current to 4%.

F06 - MANUALLY SET CEF (NOT RECOMMENDED)

DEFAULT OFF = AUTO RECALCULATION OF CEF

DISPLAY = A87 OR A90 (DEPENDS ON BATTERY TYPE)

RANGE = 65–99 STEP = 1

Allows manual set up of CEF (Charge Efficiency Factor). Default display A87 or
A90 (depending on battery type selected—see F02) indicates automatic CEF recalculation

feature. Returning to A87 or A90 from a user CEF restores the automatic CEF feature.
If a user-setup CEF has been selected it will appear as a U## ( U preceding a number) in
the DATA mode—see page 15. A different CEF may be set up for each battery; only the
selected battery's CEF will be changed.

F07 - SET TEMPERATURE COEFFICIENT

DEFAULT = 0.5 RANGE = 0.1–0.9 STEP = 0.1

This factor compensates for capacity change with temperature. Typical value 0.5%
Capacity/°C. This coefficient must be supplied by the battery manufacturer. The default
value is typical for lead acid liquid or gelled batteries. Normally this value is not changed.

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
time remaining and percent remaining.

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 STEP = 10 AMPS

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
that the alternator can ever deliver which in turn reduces heat and wear on belts and bearings.
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
of the FREEDOM inverter (also alternator control in the Link 2000-R). This is necessary
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
(Bank 1) is substantially larger than a separate engine battery (Bank 2) that is also monitored
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.

F12 - BACKLIGHTING INTENSITY CONTROL

DEFAULT = 130 RANGE = 0–240 STEP = 10

This function may be used to increase or decrease the intensity of the backlighting
for the display.
