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

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 indi- cates 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

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, tempe

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 remo

SETUP I4.35 I4.35 I4.35 I4.35 I4.35 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. T

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. (015 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 pr

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 (page 2122) 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 i

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 slightl

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

See pages 2427 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.

When the discharge floor is set to 50%, the Time Remaining display reports time remaining until the battery reaches the 50% discharged level. You may set the discharge floor from 50% to 100% in 5% increments. When the Settable Discharge Floor is 100%, time remaining to 100% discharge is displayed. You may set a discharge floor for each battery

DATA MODE DATA: The DATA mode is used to recall key historical information about the battery (battery banks). To access the DATA mode: 1) Select Battery #1 or #2 to review its data. 2) Press and hold the SETUP button until the green LED begins to flash then release the button. 3) Now press the (blue) DATA button. Each time you press the DATA button a new piece of data is displayed. You may also hold the button down to scroll through the following data: CEF (Displayed as EXX EXX EXX EXX EXX):

HOW TO USE THE LINK CONTROL PANEL 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 says you should begin charging when your LINK 2000 shows that 50% of battery capacity has been consumed. In Marine and RV systems, which are trying to minimize charging time with an engine driven alternator or generator driven charger, the battery is normally charged only to the 85% level. This means o

parameters. The battery will be gassing and you will see an accumulation of a large number of amp hours each day. This is a clear indication that you are destroying your battery by overcharging. Check your LINK 2000 before turning off a charging source to see that you 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 overcharg

IDEAL CHARGE CURVE 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 accepting only a small amount of current. The battery is now full. Duri

HOW TO TELL WHEN A BATTERY IS FULLY CHARGED (CHARGED BATTERY PARAMETERS) MULTIPLE STAGE CHARGING SYSTEMS If you are using the charger in the FREEDOM, the battery is charged when the system 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 the charging current, at the Acceptance V oltage (14.4/28.8 V typically), drops to below 2% of the battery capacity. (See the descrip

SYNCHRONIZING YOUR LINK 2000 TO A CHARGED BATTERY A charged battery has zero Ahrs removed. Synchronizing your LINK 2000 to read zero when the battery is charged ensures that you always know the net number of amp hours 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
