SkyView System Installation Guide - Dynon Avionics

SV-BAT-320 Installationo WEAK BATTERY: SkyView detected a low battery voltage condition whenSkyView was last shut down. The battery may be discharged or may needreplacement. SkyView will annunciate a warning if this happens repeatedly.DATE OF LAST TEST: UNTESTED / MM-DD-YYYYo If this date is over a year ago, SkyView will annunciate BATTERY TEST NEEDEDupon startup. Follow the steps in the Initial / Recurrent Backup Battery Testsection below.TEST RESULT:o FAIL: VOLTAGE DROP TOO HIGH: Battery likely needs to be replaced. ContactDynon Technical Support.o FAIL: LASTED xx MINS: Battery likely needs to be replaced. Contact DynonTechnical Support.o PASS BATT LIFE > 45 MIN: The last full test of battery passedBATTERY STATUS: (voltage)CHARGE STATUS: CHARGING/DISCHARGED/CHARGED/STANDBY/NO BATTERYAn SV-BAT-320 is fully charged when it reaches 12.25 volts. Charging a completelydischarged battery may take up to 4 hours. To conserve your aircraft battery, theSV-BAT-320 only charges when SkyView detects that your alternator or generatoris running (whenever your engine is running), which is when SkyView’s inputvoltage is above 12.25V. Alternatively, connecting a battery charger to youraircraft battery will also raise the input voltage to a level that will allow SkyView’sSV-BAT-320 to charge.The SV-BAT-320 must only be charged by SkyView. External charging of the batteryis not supported. External charging of the battery can damage it or cause it toexplode.Initial/Recurrent Backup Battery TestPerform this test to ensure each backup battery in the SkyView system is fully functional uponinitial installation and yearly thereafter. SkyView records the date of the last battery test andwill annunciate, both via a message and by the “needs test” icon in the top bar, when a year haspassed since the last successful battery test.A fully charged SV-BAT-320 should power a SkyView system for at least 60 minutes if primarypower is lost. As your backup battery ages, the length of time that it can keep a SkyView displaypowered up will gradually diminish. When this time is less than 45 minutes, the battery shouldbe replaced. This test tests the actual capacity of your battery by fully discharging it whilerecording the time elapsed.If the SkyView system has more than one display with a backup battery installed, perform thetest for each display individually. Power off all but one display during the test.9-4 SkyView System Installation Guide - Revision O
