  • Page 3: Introduction And Special Notes

    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.

  • Page 4: Monitor Functions

    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. 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.

  • Page 5: Inverter And Charger Functions

    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.

  • Page 6: 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.

  • Page 7: Setup

    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) 2) Ambient Temperature (F03 page 11) The SETUP BUTTON is used to access the functions in small blue text below each button's primary function.

  • Page 8: Inverter Setup

    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.

  • Page 9: Monitor Setup

    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.

  • Page 10: Functions Setup

    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.
  • Page 11 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.
  • Page 12 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.
  • Page 13 (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.
  • Page 14 When this function is ON, the Link 2000/Link 2000-R uses the actual battery temperature reported from the Freedom Inverter/Charger through the temperature probe. If the unit Inverter/Charger does not report a valid temperature reading, the Link 2000 will use the battery temperature declared by F03 (Default: 70 °F) to set charging voltages.

  • Page 15: Data Mode

    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.

    LINK 2000 to 100% charged batteries. You would use battery #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).
  • Page 17 20 hours later, turn off the load and look at the A hrs display on your LINK 2000. The number displayed is the capacity at the test current. If less than 20 hours passed before the battery voltage fell to 10.5 V you can still determine the capacity with some arithmetic.

  • Page 18: Ideal Charge Curve

    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).
  • Page 19 5% or 10% of capacity. The LINK 2000 should be synchronized to whichever of these charge levels is reached in normal operation.
  • Page 20 This will automatically ensure that the Link 2000 stays in sync. Some things that will cause the Link 2000 to not stay in sync are: 1) discharge cycle is less than 10% of battery capacity, 2) battery not fully charged...
  • Page 21 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.
  • Page 22 Feature Summary of LINK 2000 Control Functions Green LED indicates on. INVERTER may be turned On or Off indepen- dently from charger. IDLE MODE sets the load sensitivity while idling, expressed in Watts. Range depends on Freedom inventer being used.

  • Page 23: Rules For Changing The Charged Parameters

    (1) If your charging system only reaches 13.8 (27.6) volts, a Charged Voltage of 14.0 (28.0) volts will not work—it is set too high and the Link 2000 will never know that the battery is charged. Lower the Charged Voltage. Changing the Charged Voltage to 13.7 (27.5) volts should work.

  • Page 25: High Discharge Rates And Peukert's Equation

    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.

    ERROR CODES AND TROUBLESHOOTING The following error codes are displayed when the LINK 2000 detects a problem. The display alternates between the selected monitoring function and the Error Code. The Error Code continues to flash until the error is corrected. (Error codes are the same for all models.)
  • Page 30 The reading at the shunt and at the point where the wires coming out of the meter join the shunt wiring should be the same, and when multiplied by 10 should equal the reading in the amps display of the Link 2000.

  • Page 31: Microprocessor Reset Procedure (Resetting To Factor Defaults)

    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, like all computer products, the unit is sometimes susceptible to power supply dips or surges that can cause erratic behavior or memory errors.
  • Page 32 Follow the procedure outlined on the previous page to first reset the microprocessor. Select Battery bank #1 on the LINK 2000 to reset to factory values for Battery #1. To also reset Inverter and Charger functions to factory defaults, be sure that the INVERT and CHARGE LEDs are lit.

  • Page 37: General Notes

    Before wiring the LINK 2000, install the shunt as indicated. All wiring should be done before installing the fuses. 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.
  • Page 38 remember that instrumentation and other loads grounded directly to the engine block will 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.
  • Page 39 There are three jacks on the back (bottom) of the inverter. Use the one labeled 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.
