6 V olts is electricity’ s poten- tial to do work . V oltage helps assess approximate state-of-charge and to check for proper charging. A 12 V battery is consid- ered 100% discharged when it drops below 10.5 V . Amps is the present flow of current in or out of your battery . For example, a re- frigerator may draw 6.2 amps of current. This is disp[...]

7 Intr oduction Congratulations! The Xantrex Link 10 is the most advanced (Patents Pending) DC power measurement instrument available. It shows you: Battery State-of-Charge on a multicolor light bar . System voltage accurate to 1/20th of a volt ( <20 VDC). System current accurate to 1/10th of an amp ( <40 amps). Amp hours removed from, or put[...]

8 Why monitor a battery? Batteries can be ruined by excessive discharge. They may also be dam- aged by under-charging. A battery (or bank of batteries) may be storing less energy than you think. The Link 10 provides all the key data you, or your technician, need to make decisions about battery use and charging. How does the Link 10 w o r k ? The Li[...]

9 Basic installation of the Link 10 on a 12 or 24 volt system involves only five wires. Because the Link 10 will work on systems up to 500 volts, special high voltage installation techniques are discussed beginning on page 44. Y ou need to read this section if you're working on an electric vehicle or system where more than 50 volts is encounte[...]

10 Mounting Our Patent Pending "Ratchet Ring" makes mounting easy and fast. TIP: When installing from the front of a panel or dashboard slide the Ratchet Ring onto cable with correct orientation and then connnect the wires. Push Ratchet Ring o n until firmly in contact with panel. The gasket around the ring o f the Link 10 should pro- vid[...]

13 Shunt & Battery W ir es The shunt is the current sensor for the Link 10. Its 500 A, 50 mV rating means that when 500 amps flows through it there is 50 mV generated across it. The millivolt signal is translated into an amps display in the Link 10 . For example: a 50 A load would generate 5 mV across the shunt and would be displayed as 50 amps[...]

14 Meter W iring Detail Make the necessary wire connections to the Link 10 as shown in the following diagram: CAUTION Use correct sized screwdriver for terminal screws. T ighten firmly but do not over-tighten to avoid damage Color code shown for Xantrex 4 twisted pair cable. P/Ns below: P/N 84-2014-00 -25' P/N 84-2015-00 -50' 1) For V olt[...]

15 Most failures and problems are due to wiring errors. Please double check the wiring. (Color code shown is for Xantrex wire P/Ns on page 14.) # 1 - DC Power (Black Wire) . Start at terminal #1 of the Link 10 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[...]

16 Once you have completed ALL instructions on page 15, insert the voltage sense wire fuse, then the meter power fuse. (BLUE wire fuse first, RED wire fuse last!) The fuse should be in a fuse holder and should be con- nected in a smooth motion. A "ragged" power-up may cause a meter lockup. Both the bar graph and digital display should com[...]

17 Synchr onizing the Link 10 Synchr onize the Link 10 t o a Full Battery After installing the Link 10, charge the battery until the far right Green LED begins flashing, which indicates the Charged Parameters have been met. Amp hours will have started at 0 and counted up as a positive num- ber . As you begin discharging the battery , the LED will s[...]

18 Although the Link 10 is a very sophisticated device, obtaining basic battery information from it is simple. W ith the unit turned on and the ( V olts) LED on, let's learn how to display the four most important DC system parameters. When you touch the button, you are SEL ecting the display you wish. Each time you touch SEL in normal operatio[...]

19 Reading the Bar Graph Under the LED bar graph are the words RESET RESET RESET RESET RESET, DA DA DA DA DA T T T T T A A A A A, L L L L L OCK OCK OCK OCK OCK, and FUNC FUNC FUNC FUNC FUNC . These words are ignored during normal operation. They are used to indicate programming and advanced function modes which are explained beginning on page 28. S[...]

20 Pressing and holding the SET button for three seconds enters the Setup and Advanced Functions mode. The word SEL SEL SEL SEL SEL apppears in the display , prompting you to press the SEL button to choose what function you want to SEL ect. Pressing SEL chooses a variable or function . The SETUP mode always begins at the (V olts) function. Each pre[...]

21 The first time you use the Link 10, it assumes you have 200 amp-hour lead acid batteries. If your battery capacity is different you must change the declared battery capacity . Follow these instructions to declare a new capacity: 1) Press and hold the SET button for three seconds to enter SETUP (and Advanced Functions) menu. SEL SEL SEL SEL SEL a[...]

22 The Char ged Parameters The Link 10 depends on the Charged Parameters to stay in sync with the battery state-of-charge, to automatically reset to zero, and to automatically calculate the CEF . The default settings are for 12 V lead acid (liquid or gelled) batteries. They have been carefully chosen to work on most systems, including constant volt[...]

23 Char ged Parameters & CEF If you change the Charged Parameters please use the following rules: 1 ) The Charged V oltage Parameter MUST BE A T LEAST 0.1V BELOW the voltage at which the charging system finishes charg ing. Example: If your charging system finishes the battery at 13.8 volts, a Charged V oltage Parameter of 14.0 volts will not wo[...]

24 Setting Up Five dif ferent displays are available in the T ime function. Y ou may select present consumption level, a 4-minute average, a 16-minute, or a 32-minute average, or display the percent of rate compensated capacity remaining. Which method is best for you depends on your installation. Most installa tions will find four-minute averaging [...]

25 The Link 10 may support an optional two wire temperature sensor . The temperature sensor is activated by turning Advanced Function F16 ON. W ith F16 ON, F03 shows battery temperature in degrees Celsius. When activated, F03 will continue to display temperature after exiting the Setup mode until one of the two front panel buttons, SET or SEL , is [...]

26 Peukert's Exponent is a number which describes how battery capacity shrinks as the rate of discharge is increased. The Link 10 uses a number between 1.00 and 1.50 to describe how fast a particular battery will "shrink" when a heavy load is connected. A more complete technical discussion of the Peukert Exponent, and typical value t[...]

27 Alarms T wo T ypes of Alarms The Link 10 i s equipped with both a visual Power Loss Alarm and a visual Low Battery Alarm. It is important that you understand the difference between these functions. Power Loss Alarm: Shows when power being supplied to the Link 10 has dropped to an unsafe level. Certain display features are turned off as meter pow[...]

28 In addition to reporting primary system values, the Link 10 is capable of many other front panel functions and will also display important historical battery data. The words below the bar graph display indicate which of these functions you are accessing. T o use these functions you must read and understand the following section of this manual. R[...]

33 Advanced Functions CAUTION: If you set the discharge floor high, such as 50%, and continue to discharge well beyond this point, you will notice that the bar graph does not "fill up" until you have charged the battery above the discharge floor . In other words, if you set the dischar ge floor at 50% and discharge 75%, you must recharge [...]

34 F16 TEMPERA TURE SENSOR ON/OFF This function turns the optional external temperature sensor on or off. This feature is only operable when a temperature sensor has been connected between Pin 6 and Pin 8 of the Link 10. T o fully understand this feature, please refer to F03 on page 31.

46 Electric V ehicles (EVs) The Link 10 is the ideal energy meter for EV instrumentation. It not only provides v olts, a mps, amp hours and time r emaining, it adds two impor tant bonuses: kilowatt hours and optional serial computer output. If you design or work with electric vehicles or battery-powered equipment of any type, you should realize tha[...]

47 + - - - + + EV Installations The negative of the Link 10's power supply must be common to the nega- tive of the battery (motive pack) which you are measuring.

50 High V oltage Notes IF YOU USE MOTIVE BA TTERIES TO POWER THE LINK 10: If the HV battery is "tapped" to provide meter power , it is recommended that a 24 V tap, not a 12 V tap, be used. The reason for this is that under heavy acceleration under low battery conditions, voltage may fall to levels low enough to cause the meter display to [...]
