3 LINK 20 INTRODUCTION Congratulations! Y ou have purchased the world's only Dual W atch tm battery monitor . In order to understand, use, and install it, PLEASE read this manual. It provides important information. Please contact us with suggested improvements. For Link 20 installation, operation, warranty support, and repair questions, please[...]

4 FRONT P ANEL OF YOUR LINK 20 T The exclusive Dual W atch tm light bars give you battery state-of-charge information at a glance. It's easy to train your whole crew , even the kids, to turn off loads and start charging when the light bar shows two yellow lights. When the light bar is green, you've got plenty of energy . With one flashing[...]

5 USING YOUR LINK 20 ST A TUS LIGHTS These green lights tell you what units are displayed. V olts is the electric potential to do work . V oltage is useful to assess the approximate state-of-charge and to check for proper charging. Examples: An at-rest, fully charged battery will show about 12.8 V . A 20-hour rated battery is 100% dischar ged when [...]

6 Four green lights means your battery is nearly full (80–100% charged). A single flashing red light means it's nearly discharged. Light bar scaling is independently settable. As the Link 20 comes from the factory , it is set to show a flashing red light whenever your battery is more than 80% discharged (20% charged). The default setting usu[...]

7 LINK 20 BA TTER Y MANAGEMENT SIMPLE BA TTER Y MANAGEMENT RULE: Recharge When the Battery is 50% Discharged! The Link 20 is a guide to the battery's state of charge. Our Mid-Capacity Rule says you should begin charging when your Link 20 shows that 50% (or more) of battery capacity has been consumed. In marine and R V systems, which are trying[...]

8 BA TTER Y CAP ACITY TESTING Y our Link 20 can be used to conduct periodic capacity tests that tell you the actual amount of energy your batteries can store. A capacity test should start with a battery that has been properly charged and equalized. The objective is to find the maximum available capacity . Many times, deep-cycle battery capacity is [...]

9 SYNCHRONIZING T O YOUR BA TTER Y A charged battery has zero amp hours removed. Synchronizing your Link 20 to read zero when the battery is charged ensures that you always know the net number of amp hours removed. There are two ways to synchronize your Link 20 : 1) Install the Link 20 on a fully charged battery and it will be in sync. 2) If the Li[...]

10 Y our Link 20 comes with default values chosen to work with most systems. Normally the only values that need to be changed are the battery capacity , battery type (liquid or gelled), and high discharge rate compensation (Peukert) exponent. Please be sure you understand each function before changing the factory default values outlined below . Hol[...]

Resets amp hours and allows reset of every- thing to factory default values. See page 22. USING SET AND SEL BUTTONS Pressing and holding the SET button for five seconds e[...]

12 The C The Link 20 depends on correctly set Charged Parameters to stay in sync with battery state-of-charge, to automatically reset to zero, and to automatically calculate the Charging Ef ficiency Factor of your battery . The two numbers which define Char ged Parameters are Charged V oltage and Charged Current Percent. What these Charged Paramete[...]

13 HOW T O SET Y our Link 20 automatically selects an appropriate charged voltage for 12-volt liquid and gel cells when you set battery type. (W e'll cover setting battery type on page 19). If you operate a 24-volt system, or if extremes of temperature are involved, here's how to change charged voltage: 1. Press SET for five seconds. SEL [...]

14 HOW T O SET ( B A TTER Y CAP ACITY) The first time you apply power to a Link 20 , it assumes you have two banks of 200 amp-hours battery capacity each. 200 amp hours is the factory default capacity . If your battery capacity is different (and it probably is) you must change the declared battery capacity . Before you try to set battery capacity ,[...]

15 HOW T O SET There are four different ways the Link 20 can approximate time of operation remaining. Y ou may select present consumption level, 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 four-minute average appropriate. 1. P[...]

25 SETTING PEUKERT EXPONENT When you select Battery T ype (See Function F02 on Page 20), your Link 20 automati- cally sets a Peukert exponent which is generally correct. However , your batteries may have different characteristics than "average" and you may wish to change the exponent so your T ime Remaining and Light Bar displays will be [...]

26 HIGH DISCHARGE RA TES & PEUKERT'S EQUA TION Peukert's Equation describes the effect of different discharge rates on battery capacity . As the discharge rate increases the available battery capacity decreases.

31 READ BEFORE WIRING !!!!! Before wiring the Link 20 , install the shunt as indicated. All wiring should be done before installing the meter power fuse. GENERAL NOTES 1) W ires used should be #16 or #18 A WG. (Larger wire is acceptable, but not necessary .) W iring should be in accordance with the NEC, ABYC, or other applicable standards. 2) The S[...]

32 recommend them. W ith isolated negative output alternators, 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 really the right solution and may be ordered from Xantrex T echnology Inc.[...]

33 The dual shunt is the current sensor for the Link 20 . Its 50 mV @ 500 A rating means that when 500 amps flows through it, 50 mV is generated across it. The millivolt signal is translated into an amps display in the meter . For example: A 50 A load generates 5 mV across the shunt and would be displayed as 050 amps. Caution: In the diagram below [...]

34 Make the necessary wire connections to the Link 20 as shown in the following diagram: WIRING CONNECTIONS T O THE Link 20 1- BLACK 2- GREEN 3- ORANGE 4- BLUE 1 2 3 4 5 5- RED 6 8 7 8- BROWN 7- YELLOW 6- VIOLET NOTE: BE SURE TO USE TWISTED WIRE FOR GREEN & ORANGE AND YELLOW & BROWN SHUNT SENSE P AIRS. 4 twisted pair cable CAUTION Use corre[...]

35 Most failures and problems are due to wiring errors. Please double check the wiring. (Color code shown is for Xantrex cable) # 1 - DC Power (Black Wire) . Start at terminal #1 of the and follow it to the big bolt on the Load side of the shunt. Do not connect this wire to the small screw terminal with the Green shunt sense lead. # 2 Shunt Sense L[...]

36 MOUNTING Surface mounting (Recommended method) . Y our Link 20 is supplied with a nesting-type mounting place which allows suface mounting using our exclusive Thin-Mount technology .

37 REMOVING THE UNIT T o demount the Link 20 from the nesting r eceptacle, insert a small coin, knife blade, or small screwdriver blade and press inward while gently pulling the meter away from the nest. Press in on this tab with a thin metal coin while pulling one side of the unit away from the nesting receptacle.[...]

38 Once you have completed ALL instructions on page 35, insert the voltage sense wire fuses (Blue W ire to fuse holder on battery #1, V iolet Wire to fuse holder on battery #2). LAST , install the meter power fuse—Blue and V iolet wire fuses first, RED wire fuse LAST! The fuse should be in a fuse holder and should be connected in a smooth motion.[...]
